PLAN No. 1139. OXY-ACETYLENE WELDING

ACKNOWLEDGMENT

Federal Board for Vocational Education, under the direction of Charles

H. Winslow, Chief of the Division of Research. Acknowledgment is due to

Dr. John Cummings of the Research Division for editorial assistance.

WHAT THE WELDER DOES

He handles a torch, or blowpipe, at the tip of which a flame is produced

by the burning of a mixture of two gases--acetylene and oxygen. A high

degree of heat is produced by this flame, which can be concentrated at

any point by proper handling of the torch.

The welder’s activities may be divided into two operations--welding and

cutting.

WELDING

In welding, metals, like or unlike, are joined together by melting them

until they fuse, “adding material” being used where it is required. The

welder also builds up worn parts or adds metal where it is lacking.

Common metals which can be treated by this process include the

following: Cast iron, steel, malleable iron, aluminum, copper, brass,

bronze, lead, and nickel. Precious metals also can be welded. Each metal

has its peculiar characteristics and mode of treatment, and the welder

who would turn out a good job must master the special technique for

handling each metal.

Welding forms the larger part of the welder’s activities. It is much

more difficult than cutting, and also has a wider field of application.

CUTTING

Cutting can be learned in a few hours. It is restricted in its scope, as

it can be used only on steel and wrought iron. The cutting torch is

similar to the welding torch with the difference that it is equipped

with a special outlet for oxygen under pressure. The operator turns on

his usual welding flame until the object is heated to a cherry red, and

then presses a device which turns on the oxygen, causing the metal to

burn away rapidly. The torch is then advanced slowly along the line of

the cut to be made. By practice comes the knack of steadiness and of

moving the torch at just the right speed to cut clear through the

metal--not too fast for complete penetration, nor too slow, causing loss

of oxygen.

WORK IN THE OPEN AND IN THE SHOP

Where the job can not be brought into the shop, welding and cutting are

done out of doors, and may be carried on under all conditions of

weather. Very commonly the process is used in cutting scrap, wreckage,

and piling, and in welding piping and mains.

Inside work varies from shop to shop according as the shop is part of a

manufacturing plant or of a foundry, or is purely a job welding shop.

Some account of the common uses of the processes in different industries

is given in the section below on “Industrial Applications.” In steam and

electric railway shops and yards, in shipbuilding, in the manufacture

and repair of automobiles, in installing pipes and mains, in sheet-metal

and metal plate work, in the manufacture of furniture, containers and

other metal products, and in foundry work, welding and cutting is being

extensively used to-day, and each day the welder’s field of operations

is still further extended.

WHAT LOCALITIES NEED WELDERS?

The answer is: All localities where industrial plants are located, or

where street railways are operated, or where farm machinery and

implements are made or repaired, or where automobiles are used or built.

Such localities will probably include your own home town or some town

not far away from home.

THE WELDER’S TOOLS AND EQUIPMENT

The numerous makes of torches on the market are of two general

types--the medium, or positive, pressure torch; and the low pressure, or

injector torch. Practically all the oxygen used comes in compressed form

in cylinders. Acetylene is more commonly generated on the premises,

owing to the cheapness of this method. It is piped into the buildings

and is always readily accessible. Generators, like torches, are of

various makes, but they vary in type to correspond to the two kinds of

torches, _i. e._, pressure generators, and low-pressure generators.

Generators are automatic in their action, being controlled by the flow

of gas. Where the gas is not generated in the establishment, and

especially in outdoor work, dissolved acetylene is used. This comes in

cylinders which are filled with porous material and contain acetone, a

liquid, in which the gas is dissolved under pressure.

Welding equipment varies according to circumstances. In general a

welding unit includes welding and cutting torches; hose and connections;

oxygen and acetylene regulators and gauges; a supply of various tips;

filler rods; goggles; friction lighters; gloves; asbestos sheets;

fluxes; hand tools, such as pliers, files, hammers and cold chisels;

welding table; preheating arrangement; fire brick; carbon blocks; and

V-blocks. It may include also, hand shear, anvil, hand forge, bench and

pipe vises, emery grinders, drill press, hack saw, jigs, lathe, hoist,

and work bench.

Practically all of the necessary equipment is furnished to the welder,

sometimes with exception of goggles, gloves, and overalls or leather

apron, which the welder may have to obtain for himself.

WHY TAKE TRAINING?

The aim of re-education is to turn out a good welder who has not only

the manipulative skill, but who in addition is well-grounded in the

necessary theoretical knowledge. It can not be too strongly pointed out,

in the view of the highly unsatisfactory method of turning out welders

obtaining in the past, that the course can not be too thorough. The need

is for good welders, not for half-trained men. Really good welders in

this country are not many, and there is in this field a splendid

opportunity for the well-equipped man, but for him only. An employer

will always be looking for a better man if he has a half-trained man on

the job.

OVERCOMING YOUR DISABILITY

The question is not primarily one of the handicap, but rather of the man

behind the handicap. It is not the exception, but rather the rule, that

a partially handicapped person, endowed with ingenuity will, even though

at a disadvantage, beat the sound man who does not possess any

ingenuity. This is borne out by numerous instances of foreign experience

in re-education.

This applies, of course, especially to the less serious disabilities and

not at all to those which are manifestly debarring. In the case of a

welder, the latter would include blindness or defective vision,

paralysis, shell shock and nervous disorders, loss of both arms or

hands, tuberculosis, ankylosis of the upper members, spinal trouble,

stiff neck, and dizziness.

Ankylosis of the knee or wrist might be overcome to some extent.

Amputation of one leg will simply limit the field of activities. Where

both legs are gone it would still be possible to enter some specialized

field where work at the bench is all that is required. In such cases,

however, it might be advisable to take up soldering or electric

resistance welding. Loss of limbs would be an embarrassing handicap for

most jobs, and prohibitive for outside work which necessitates climbing,

crawling, stooping, or getting into abnormal positions. Men who have

trouble in getting about should not enter this field. Only physically

sound men should undertake work in confined spaces, in a boiler for

example. One partially amputated arm would probably not be deterrent.

Indoor work is manifestly unsuited to men with weak lungs, as the air in

the shop is generally more or less heated and vitiated. Outdoor work

might be pursued with benefit. Men with weak backs would generally be at

a disadvantage. Kidney or intestinal trouble might or might not be

deterrent, depending on the gravity of the trouble and the degree to

which physical stamina and general health are affected. Rupture would

not be a handicap except where heavy work is to be done, and in that

class of work there is usually a helper around. Impairment of efficiency

due to loss of one eye, which may make difficult the acquirement of

precision in distancing the flame from the material to be welded, may

nevertheless generally be overcome.

The welder must have one good arm and hand with which to hold and

manipulate the torch, and enough of a stump left in the other arm to be

capable of using the filler rod and of puddling. Amputation, ankylosis,

or paralysis of a finger or two are not prohibitive, so long as the

proper grip and manipulation of the torch can be preserved.

DEVICES FOR OVERCOMING HANDICAPS

Special “automatic pincers” are being used by French autogenous welders,

to take the place of a missing hand, for those who have lost only part

of the forearm. Drawings of this appliance are here given. The upper

drawing shows the opening of the pincers through extension of the

forearm, and the lower two drawings represent modification of the upper

pincers for the use of welders.

Those who are incapable of using their hand through any cause are

equipped with a special tool holder which is attached to the forearm.

Where the handicap consists of the loss of an arm, cutting may be taken

up to advantage. There is restricted field of employment for disabled

men in the operation of automatic welding or cutting machines.

SAFETY AND HYGIENE

As in other occupations, there are in welding, certain safety measures

to be taken to avoid accidents. These are clearly defined and are made

an integral part of the welder’s training until observance becomes

automatic.

This applies, of course, to the man who is physically sound as well as

to the disabled. In the case of the handicapped, the matter becomes one

of ascertaining if the disability interferes with the carrying out of

these safety measures; and if so, if the difficulty can be overcome. If

not, some other occupation must be selected. In the welder’s case,

however, these precautions are mostly “don’ts,” and do not present

serious difficulties to be overcome.

Acetylene is not poisonous and the impurities in the gas which are

poisonous are not present in sufficient quantity in the American carbide

to be dangerous. The characteristic odor of the gas is a protection

against fire, explosion, and suffocation. One cubic foot thoroughly

mixed with 10,000 cubic feet of air can be detected.

HOW PREVIOUS EXPERIENCE HELPS

In selecting any vocation, a man’s former occupation must be carefully

taken into account, and particularly is this true in the case of

welding. Previous experience, training, and education are such important

factors in the student’s success or failure that particular attention

should be paid to them. Experience as a blacksmith, machinist,

boilermaker, patternmaker, sheet-metal worker, molder, electrician, and

in kindred occupations will be in every case of great value.

All experience in handling metals, as well as all mechanical experience

is a valuable asset. For a man who has had such experience, it will be

comparatively easy to become a good all-round welder. It goes without

saying that no disabled man should take up the course unless he feels an

interest in the work or in some special branch of it. It is this

interest coupled with ingenuity which will make it possible for the

welder to handle new problems successfully and to devise better and more

efficient ways of doing things.

In the case of a former welder who is capable of taking up his former

vocation, a short course of training will suffice. A former welder whose

handicap prevents him from taking up his old trade may, with the proper

training and necessary qualifications, become an excellent teacher, a

welding foreman, or a superintendent.

ARE WELDERS GOING TO BE NEEDED?

The process is of comparatively recent application, dating back to about

the year 1904. Its growth has been extremely rapid, especially of later

years, as regards development of technique, extension of its

applications, and perfection of apparatus. Regardless of this progress,

however, it is no exaggeration to state that the process is as yet in

its initial stages, and that in the near future its field of utility

will be greatly extended. As contrasted with the growth of oxy-acetylene

welding, the supply of good welders has lagged far behind the demand.

Unlike European countries, this country has only lately come to realize

the importance of well-grounded, thorough, practical training for

prospective welders. In view of these two factors--the remarkable

expansion of the process and the shortage of welders--prospects look

bright for the future.

QUALIFYING AS A TEACHER OF THE WELDING PROCESS

In any occupation where the demand for labor is increasing rapidly,

there is bound to be a demand for men to teach the processes and

practice of the occupation. If you master the trade you yourself may

qualify as a teacher.

GETTING TO WORK AFTER TRAINING

In contemplating placement after training the following factors are to

be taken into account:

Your choice of a field.

Your special fitness.

The industrial demand.

It is the disabled man’s privilege to decide what he will specialize in

and he will be allowed the freedom of choosing which branch of welding

he will take up, such choice being of course subject to the guidance of

the vocational adviser.

Most welders will exhibit a tendency toward some special branch or type

of welding, even while they are learning the art. The instructor will

keep in constant touch with the pupil during the course to determine if

there is such a trend in him, and if so to encourage it. Some take to

one metal in preference to others; some to one operation in preference

to others; some may give evidence of ability as all-round welders.

The demand for welders is so varied that knowing the demands in general

it will in most cases be possible to satisfy preferences and special

aptitudes. This will be the aim always.

If as a trained welder you desire to get started on your own hook,

several questions will arise in your mind?

Where shall I be located?

What are the demands of the locality in which I shall live?

What is my fitness for the work?

How about the necessary equipment?

The locality should be such as to give you ample opportunity to make

good. It might be hard for you to go against much competition at the

start. Likewise, to act as a pioneer of the industry in some locality

which knows nothing about the work, might not be desirable.

In placing retrained welders, local demands will be carefully considered

to the end that no man shall be placed where he may have work coming in

which he is not capable of handling efficiently.

WHAT IF YOU DO NOT TAKE TRAINING?

You will not be a real welder; probably you will not get a chance to try

your hand at manipulating the torch at all. If you do get a chance you

may get hurt or hurt others trying to weld without training for the

trade. Train for it, and then go to it, and if you fail come back for

more training or for training in some other trade.

INDUSTRIAL APPLICATIONS

Some idea of the wide range of application of the oxy-acetylene

processes may be gained from a brief survey of their uses in several

industrial fields.

PLAN No. 1140. STEAM RAILWAYS

Oxy-acetylene welding is used in the shops of practically every railroad

in the country as a means of reducing cost of repair and of reclaiming

worn parts. Each craft usually does the welding of metals that

originates in its department: Blacksmiths handle wrought iron and steel;

boilermakers, boiler plates and flues; machinists, cast iron;

coppersmiths, brass pipe work.

The process is generally used in the reclamation of broken engine

frames, damaged cylinders, broken spokes in driver wheels, cracked valve

chamber bushings, broken steam and exhaust pipes and air pump heads; in

mending cracks, cutting out and welding patches on side sheets of fire

boxes, flue sheets and door collars; in welding front end doors when

damaged, engine truck frames and cradles, frame braces and brackets,

tender bolsters, guides, and pedestals. The process is used to some

extent also in building up worn diamond crossings and frogs. Both

cutting and welding are used in the upkeep and repair of steel cars.

At the scrap yard the welder cuts up old boilers and other scrap for

salvaging.

PLAN No. 1141. ELECTRIC RAILWAYS

Applications of the process by electric railways are similar to those by

steam railways. There are, however, more opportunities for doing welding

at the table. Of such a nature are restoring of armature bearing

housings and frame heads, worn axle seats for motors and axle caps,

journal boxes, pinion seats and keyways, brush holders, trolley bases,

and third-rail shoe castings. Heavy broken parts such as truck frames,

drawheads, brake hangers and body bolsters are repaired. To some extent

the process is used also in bonding rails and in welding steel trolleys.

Most of the work is handled in the shop, where, however, electric

welding is coming into more general use, owing to the availability and

economy of electric power.

PLAN No. 1142. SHIPBUILDING

Extensive use is made of the process in cutting all kinds and shapes of

steel plate. Hydrogen is very generally used, instead of acetylene, and

welding machines have been introduced. Welding proper is more generally

applied in reclamation work, damaged or broken parts of the ship and of

its machinery and propellers being often welded by this process.

Electric arc welding is fast coming to the front in this field, except

for cutting where the gas process can not be replaced.

PLAN No. 1143. AUTOMOBILE INDUSTRY

Oxy-acetylene welding of automobile parts is not in general very

difficult, but as in all other welding mastery of fundamentals is here

also essential to success. The work is varied in character, including

cast iron, aluminum, steel, and wrought iron welding.

The process is extensively used in the repair of automobiles, and to a

lesser degree in their manufacture. Both the industry itself and the

repair work provide excellent fields for the prospective welder.

Repair work is done generally in either a job welding shop, where a

number of welders are employed and where all kinds of welding is carried

on, or else in a garage or automobile repair shop where a welder is

employed to do the necessary work. In small communities the welding shop

is usually run by one man who owns it and who does all the welding. In

the large welding shops acetylene is generated; in other cases dissolved

acetylene is used. A welder who is expert in the welding of aluminum is

particularly valuable in this work.

In manufacture, the work is done in the shop. It is often simple and

well suited to workers who must elect a sedentary employment. The

process is broadening its scope in this field.

Closely related to the automobile is the motorcycle. A number of its

parts, such as handlebars, special jigs and muffler heads, are welded in

manufacture. In repair work the scope is somewhat similar to that of

automobile repairing.

PLAN No. 1144. PIPE AND MAIN WORK

In the welding of pipes and mains, the process is finding increased

application and this field presents good prospects of expansion in the

future. Extensive work in this country as well as in Europe, where it is

more largely used, has demonstrated that welding is not only the most

economical method but as well the most efficient in that leaky joints

are eliminated. Welding does away with threaded joints, and thus makes

possible the use of much lighter pipe, since there is no need for making

allowance in thickness for threading. Moreover, joint couplings are

dispensed with. The expense saved in maintenance alone is tremendous, as

the joint is water-tight and there is therefore little likelihood of

trouble arising from leaks. In making connections, Y’s, T’s, crosses and

drips are made on the spot, being cut out of odd lengths of pipe and

fitted together. This effects an economy in that these odd pieces are

saved.

The process has its greatest application in the welding of gas, steam,

air, oil, water and ammonia pipes and mains, and the work is chiefly

outside work, although it is used to some extent on interior pipe

connections. Special fittings or connections may be welded in the shop.

Outdoors welding is generally performed on sections of pipe while above

the ground, the whole section being finally lowered into the ditch. The

welding of these several sections to each other has to be done in the

ditch or trench, a pit being generally dug in order to give the welder

sufficient room for carrying on the work. Obviously this work requires

suppleness in the worker.

Where there is a large amount of welding, the apparatus most commonly

used is a portable generator, with which is mounted a set of oxygen

tanks. In other cases a small two-wheeled truck carrying one oxygen and

one dissolved acetylene cylinder may suffice.

In this kind of work, the welder is generally assisted by one or two

helpers who do the heavy work, placing, holding, and turning the pipes

while the welder keeps on welding. Some overhead welding is done which

forces the welder to assume a strained position.

PLAN No. 1145. SHEET METAL

Welding sheet metal is an important application of the process, which is

superseding to a large extent riveting and soldering. Very careful work

may be required but in the main the work is not particularly difficult,

and it can be easily mastered if the training given is thorough.

Electric resistance welding, however, is superseding oxy-acetylene in

many manufacturing operations.

PLAN No. 1146. METALLIC FURNITURE

Extensive use of oxy-acetylene welding is made in the manufacture of

metallic furniture and in kindred trades. Welding is an efficient and

economical way of joining various parts together, as well as of making

the parts themselves. The work may be more or less routine and much of

it is done at the bench. This is a comparatively easy type of welding,

in which a man can become proficient in a short time. It would be

eminently suited to the welder who has trouble in going about or who is

easily fatigued, and who would be better off in some sedentary work. The

process is largely used in the manufacture of steel desks, chairs,

filing cabinets, office safes, stepladders, and surgical, hospital and

dental furniture.

PLAN No. 1147. CONTAINERS

Welding is fast superseding old methods in the manufacture of containers

of various kinds out of sheet metal. In this class is included the

manufacture of steel barrels, range boilers, kitchen utensils, light air

tanks, and storage tanks. This kind of work needs a well-trained man on

the job. Except in the case of larger objects, the work can be done at

the welding table, and it is not of a straining nature.

PLAN No. 1148. METAL PLATE

Metal plate welding is quite similar in its scope to sheet metal work.

It is largely used in the manufacture of ammonia and air receivers,

vacuum driers, steam driers, and vats. The process is not used in boiler

work to any extent, as the consequences of a faulty weld might be

extremely serious.

PLAN No. 1149. FOUNDRIES

In steel foundries the process is extensively used in cutting away

risers, gates, and heads from castings. As compared with the old method

of cutting with a saw, the gas process is much quicker and much more

economical. This sort of cutting work is simple and does not require

great dexterity. The welder should be capable of bending over or

assuming more or less cramping positions, as he has to work on the

castings in positions in which they have been left on the floor. Welding

is almost universally used in the reclamation of defective castings, and

by this process castings are saved which for some slight defect would

have been consigned to the scrap heap. The process finds application

also in the welding of blowholes, cold shuts, porous spots, and cracks.

It is used to some extent in manufacture, two parts being cast

separately and joined by welding.

PLAN No. 1150. FORESTRY PURSUITS

ACKNOWLEDGMENT

This monograph was prepared by Capt. S. T. Dana, in the Forestry Service

of the Department of Agriculture, under the direction of Charles H.

Winslow, Chief of the Research Division of the Federal Board for

Vocational Education. Acknowledgment is due to Dr. John Cummings of the

Research Division for editorial assistance.

WHAT FORESTRY IS

Forestry is the business, or the art, or the science, depending on the

point of view from which you look at it, of handling forests for timber

production or stream-flow protection. It does not, as is often

mistakenly thought, have anything to do with fruit trees, or even with

street and park trees. The care of these comes under horticulture and

arboriculture. Forestry is distinct from either in that it has to do

primarily with entire stands of trees, or forests, rather than with

individuals. Forests are really nothing more nor less than tree

societies, or communities, comparable in many ways with human

communities, every member of which has an influence upon and in turn is

influenced by its neighbors; and it is this fact that gives to forestry

its distinctive character.

Forestry should also not be confused with lumbering. Lumbering has to do

merely with harvesting the trees on any given area, with cutting them,

transporting them to the mill, and converting them into lumber or other

products. While the chief task of the forester is to manage forest

lands, he has to do with the production of trees as well as with their

utilization. Forestry is concerned fully as much with the future as with

the present. Like agriculture it looks forward to keeping the land

continuously productive by the growth of successive crops. Only in the

case of forestry the crops instead of being wheat, or rye, or corn, are

trees, which in turn can be converted into fuel, fence posts, telephone

poles, railroad ties, wood pulp, lumber, and a host of other wood

products. How much the forests mean to the economic development of a

community through the crops which they produce and the employment which

they offer is evidenced only too plainly by the desolation which has

followed destructive lumbering in many a once prosperous forest region.

In addition to yielding crops which have a commercial value, forests in

mountainous regions perform another important function which is none the

less valuable because its benefits are difficult to measure in dollars

and cents. By decreasing erosion and regulating stream-flow the mountain

forests conserve water for domestic supplies, irrigation, power, and

navigation, and at the same time help to lessen the damage caused by

destructive floods. So far-reaching is this influence and so great is

the population affected by it, that the treatment which such forests

receive becomes a matter of vital interest to the general public. One of

the primary concerns of forestry is to see that they are handled in such

a way as to afford the maximum amount of protection, even if this

involves, as it not infrequently does, the restriction or entire

prevention of lumbering operations.

WHAT FORESTERS DO

In order to handle to the best advantage the area under his charge there

is a wide range of work which a forester may be called upon to do. He

must be able to identify different kinds of trees and must know the uses

to which each can be put and the sites to which they are best adapted.

He must be able to map the area and to determine the amount and value of

the timber upon it. He must be able to draw up a complete plan for

protecting the forest from fire and to carry out the details involved in

its execution. He must know how to control the attacks of destructive

insects and fungous diseases. He must be able to handle the many details

connected with the collection of seed and the production of young trees

in forest-tree nurseries. He must know where and how to plant these, or

how to sow the seed on areas where this is preferable. He must know

whether any given stand is too dense, and if so, what and how many trees

should be taken out to stimulate the growth of those that are left. He

must be able to determine the rate at which trees are growing and the

age at which they should be cut and to make plans for harvesting them in

such a way as to secure natural reproduction. And finally, he must be

able to draw up a “working plan” providing in detail for the handling of

the entire forest in such a way as to keep it continually productive.

All of this obviously involves a good deal of office work in the

formulation of plans, the maintenance of records, and the miscellaneous

administrative work connected with any business enterprise. It also

involves a good deal of practical out-of-door work. The average forester

must take long walks and horseback rides. He must often camp out in a

tent or with no shelter whatever. He must take his part in fighting

forest fires, which means the liberal and energetic use of the axe, the

mattock, and the shovel. He must run compass and transit lines, and make

topographic maps. He must estimate the size and contents of standing

trees by the use of calipers and height-measures, and must scale the

fallen timber. He must mark, or blaze, the trees to be removed in

lumbering and must see that the operations are carried out in accordance

with the approved plans. He must collect tree cones, extract the seeds

from these, sow them in the nursery, care for the young seedlings, and

later set them out in the forest.

He must also do a hundred and one other things which are not strictly

forestry but which are so closely connected with it that they must be

handled by the forester along with his other work. Grazing is a good

example of this, since most of the forest regions in the United States

produce forage as well as trees. In order to utilize this to best

advantage the forester must know how many stock the range will support

and how they should be handled. In regions where mineral deposits occur

he must be familiar with the mining laws and must have at least enough

knowledge regarding mining to enable him to deal intelligently with

prospectors and others. Since most of the forests occur in undeveloped

regions he must know how to open these up by building ranger and lookout

stations and by constructing such other permanent improvements as roads,

bridges, trails, and telephone lines. In short, the average forester,

particularly in pioneer regions, must be a veritable jack-of-all-trades.

WHERE FORESTERS WORK

Forestry is primarily an out-of-door occupation. Some indoor work in the

formulation of plans, writing of reports, handling of correspondence,

and other office routine, is of course necessary, particularly in the

case of those charged with the administration of large areas. But the

average forester must spend the bulk of his time in the open, in the

forests for which he is caring. Sometimes his headquarters may be in a

small town or sometimes in a more or less isolated situation in the

woods themselves. In either case his daily work will ordinarily take him

into the open in sunshine and in rain. Occasionally he may be absent

from home for several weeks at a time carrying his bed and provisions on

his back, or, if he is fortunate, on a pack animal.

So far as geographical location is concerned, opportunities for

foresters have heretofore been mainly in the mountain regions of the

West where the National Forests are located. As forestry comes to be

practiced more and more on State Forests and on private lands, however,

similar opportunities will develop in the East. There is no reason why

large numbers of foresters should not eventually be employed wherever

forests occur, and this means practically throughout the country except

in the Great Plains and in the farming regions of the Central States and

Middle West.

WHAT HANDICAPS ARE SERIOUS

Generally speaking, a forester must be able-bodied and in good physical

health. He must have a strong heart, sound lungs, and a constitution

able to stand exposure to all kinds of wind and weather. Heart disease,

tuberculosis, and other serious organic troubles are handicaps that

point to the choice of another occupation.

On the other hand, there are certain disabilities, and particularly

injuries of various sorts, that do not constitute any serious drawback.

Injuries to the mouth, nose, ears, scalp, and other parts of the head,

for example, do not disqualify unless they interfere to a dangerous

extent with one’s eyesight or hearing. Some deafness is allowable

provided it has not gone so far as to prevent communication or to

endanger one from falling trees or other accidents. Even blindness in

one eye is not a real handicap if the other eye is still sound. The loss

of an arm or a leg incapacitates a man for the physical work required of

most foresters, but minor injuries to these limbs, such as loss of a

finger or a toe, do not disqualify one.

For certain specialized duties one can have sustained even more serious

injuries and still be able to give satisfactory service. One may be

badly crippled and yet be successful in research work provided he is

able to move about more or less freely, has some use of his arms, and

can handle a microscope. Men at fire-lookout stations need little more

than good eyes and sufficient hearing to use a telephone. On the other

hand, one would hardly wish to take up fire-lookout work as a permanent

occupation, and unless his condition can be improved sufficiently to

enable him to resume active physical work his chances for advancement

are poor. Special appliances for handling tools are not necessary, as is

the case with many industrial workers. The average forester must be able

to turn his hand to a wide variety of activities and to use such homely

implements as the axe, the hammer, the shovel, and the mattock.

The danger of further injury is no greater in forestry than in most

other outdoor occupations. Accidents due to forest fires, bucking

horses, falling trees, and rolling stones are always possible, but the

proportion of those seriously injured in such ways as these is not

large. Those employed by the National Government receive compensation in

case of injury incurred in line of duty.

WHAT TRAINING IS NECESSARY

Forestry requires the services of three more or less distinct grades of

workers--the professional forester, the forester ranger, and the forest

guard. The professional forester handles the larger and more technical

phases of forest management. He determines what the forest under his

charge contains, how much it is worth, how fast it is growing, when and

how it should be cut, what kinds of trees should be favored, and other

questions of the same kind; and also exercises general supervision over

the execution of whatever measures are decided upon. The forest ranger

acts as a sort of semi-technical assistant to the professional forester.

He does not need so thorough an education as the professional forester

but must have sufficient technical knowledge to enable him to carry out

intelligently the plans formulated by the latter. His work is to a large

extent “practical” and involves the routine of fire protection and fire

fighting, marking the trees to be removed in timber sales, scaling the

felled logs, handling planting operations, surveying, building trails,

running telephone lines, and doing other work connected with the

administration of the forest. The forest guard is ordinarily a

non-technical assistant who helps the forest ranger in those aspects of

his work which require little or no knowledge of forestry. Forest guards

are frequently appointed for short periods only to help the regular

force during the busy season and particularly in the work of fire

protection and fire fighting. Previous experience in the woods or in

similar occupations such as lumbering and surveying constitutes a

valuable, but not essential, preliminary training for foresters of all

grades.

Twenty-five years ago the professional forester was almost unknown in

this country and there was not a single educational institution at which

he could secure the necessary training. To-day the profession is well

recognized and there are more than 20 schools offering instruction of a

grade similar to that required of civil engineers, doctors, lawyers,

ministers, and other professional men. As a basis for the more technical

phases of his education the man who desires to become a professional

forester must have had courses of collegiate grade in botany, geology,

organic chemistry, mathematics through trigonometry, plane surveying,

mechanical drawing, economics, and either French or German, or

preferably both. With these as a foundation he is ready to go ahead with

the technical subjects such as dendrology, silvics, silviculture, forest

mensuration, forest valuation, forest management, and forest regulation.

Obviously a comprehensive training of this sort can not be obtained with

less than four years of collegiate work, at least two of which must be

devoted almost entirely to professional forestry subjects. If a man has

already had a college education, however, he can readily prepare himself

for the profession by two years of post-graduate work. The degree of

bachelor of science in forestry is usually given on the completion of a

four-year professional course, and of master of science in forestry, or

master of forestry, on the completion of a five-year professional course

or of two years of postgraduate work following four years of regular

college work.

For the forest ranger no such intensive training is necessary. With a

high school education as a background, one year of rather elementary

training in such subjects as fire protection, surveying, timber

estimating and scaling, nursery practice, methods of planting, range

management, and report writing is sufficient to enable a man to qualify.

In general, the course covers much the same ground as that taken by the

professional forester, but in a much briefer and more elementary way.

Those who have already had considerable practical experience along these

lines can secure a sufficient foundation for their work in three or four

months, although even for such men the longer course is preferable if

time to take it can be found. Many of the forest schools of the country

now offer courses of this sort and the opportunities for instruction are

ample.

Since forest guards are engaged almost wholly on nontechnical work no

particular course of training is necessary. No one with any ambition,

however, would wish to remain a forest guard indefinitely when other

opportunities are open to him merely by taking a free course of

instruction. If one wishes to take up forestry, therefore, and is not in

a position to take the professional course, he should by all means

attempt to qualify as a forest ranger. Should lack of other openings

then make it necessary for him to serve as a forest guard for the time

being, he would be in a position to take advantage of the first

opportunity for advancement.

WHAT OPPORTUNITIES ARE OFFERED

Opportunities for employment for foresters may be classed as fairly

good. The point has now been passed where the supply is totally

inadequate to meet the demand, but at the same time the war has greatly

depleted the ranks of foresters throughout the country, and there is no

question that many new men will be needed during the process of

reconstruction and afterwards. The National Forests already offer

opportunities for the employment of many men and it can not be doubted

that similar opportunities will soon be offered in State forests as well

as in the case of forests still in the hands of private owners. With the

steady decrease in the timber supply, the Nation will soon be face to

face with the necessity of practicing forestry extensively as a national

safeguard and unless private owners take upon themselves the task, there

is little question but that the Federal and State Governments will take

matters largely into their own hands.

Altogether it is a safe prediction that any one who desires to engage in

forestry and who qualifies himself for the work will be able to find

employment. The entering salary for forest guards in the national

service averages about $900 a year and for forest rangers about $1,100 a

year. Technically trained foresters ordinarily enter at approximately

the same salary as forest rangers, $1,100 or $1,200 a year, but with

greater opportunities for advancement later. In State and private work

approximately the same entering salaries may be expected although some

private owners may be unwilling to pay quite so much to forest guards

and forest rangers at the start.

WHAT ARE THE CHANCES FOR PROMOTION?

Chances for limited promotion are reasonably good. It should be

recognized frankly, however, that one can not hope to get rich in the

profession and that a comfortable living is all that can ordinarily be

looked forward to. In exceptional cases unusually able and well

qualified men will doubtless be able to draw salaries of $4,000 or

$5,000 a year. The average professional forester, however, can hardly

hope to advance much beyond $2,500 or $3,500 a year except by acquiring

an interest in some lumber business or in the forest itself. For the

forest ranger a salary of $1,500 or $1,600 may reasonably be looked

forward to. Moreover, this salary often carries with it a ranger station

which can be occupied as long as he stays in the service, and also an

opportunity to produce some crops for his own use. Forest guards can

hardly hope for more than $900 or $1,800 a year.

In other words, in forestry, as in all other professions, the better

educated you are the better are your chances for promotion. Even at

best, however, the chances for large salaries are small and those who

are bent on getting rich should look elsewhere for an opportunity to do

so. On the other hand, one who is satisfied to make a comfortable

living, to spend a large part of his life in the open, to occupy a

responsible and respected place in his home community, and to enjoy the

satisfaction which comes from having an important share in a work of

great public service, can not look for a more congenial or attractive

occupation than forestry.

APPENDIX ON FORESTRY SCHOOLS AND COURSES

These lists have been compiled by the Forest Service to aid in answering

inquiries as to institutions at which instruction in forestry may be

obtained. While every effort has been made to avoid errors, the Forest

Service does not vouch for the completeness of the lists, their

accuracy, or the relative merits of the courses offered. More detailed

information regarding opportunities for disabled soldiers and sailors to

take training courses in forestry may be obtained from representatives

of the Federal Board for Vocational Education.

PLAN No. 1151. AUTOMOBILE MAINTENANCE AND SERVICE

ACKNOWLEDGMENT

This monograph was prepared by Charles W. Sylvester, under direction of

Charles H. Winslow, Chief of the Research Division of the Federal Board

for Vocational Education. Acknowledgment is due to Dr. John Cummings, of

the Research Division, for editorial assistance.

In no other industry, perhaps has progress been so rapid and marvelous

as in the manufacture and maintenance of automobiles, which to-day

employs hundreds of thousands of men and women in a great variety of

occupations, and represents investment of many millions of dollars.

Two great divisions of the industry may be made, one including the

manufacturing plants which produce new cars, and the other, the

maintenance and service shops and departments which operate and keep

cars in repair and good running order. This monograph deals with

occupations in “Automobile maintenance and service.”

WHAT MEN DO IN THESE OCCUPATIONS

In automobile maintenance and service, specialization is rapidly

creating six principal groups of workers. It is true that in small

garages one man may “tinker” with all parts of an automobile, but it is,

in fact, just as essential to employ, for example, a battery specialist

for a machine as it is to employ an eye specialist for a person.

The six groups include: (1) Repair-shop men, who deal primarily with the

mechanical treatment of the car when it has been disabled; (2) starting

and lighting experts, who repair and adjust electrical equipment,

including wiring, lights, motors, and generators; (3) ignition experts,

who look after the testing, adjustment and maintenance of current

supply, short circuits, contact breakers, vibrators, spark plugs, coils,

condensers, connections, distributors, and magnetos; (4) storage-battery

men in stations where batteries are charged, repaired, rebuilt, tested,

and kept in good working condition; (5) tire-repair men, who take care

of the splicing, patching, retreading, building up, inside repair, and

vulcanizing of casings and tubes that have been disabled by punctures,

blisters, blow-outs, rim cuts, and general wear; and (6) automobile and

truck drivers, who are responsible for operation of cars on the road.

The work of these groups embraces a greatly diversified field of

employment and offers a wide range of occupational choice.

[Illustration: Plan No. 1150. Auto Repair]

WHERE MEN IN THESE OCCUPATIONS WORK

Men are employed in the maintenance and service of automobiles and

trucks in every community. In every village, town, and city shops and

service stations are to be found.

Private garages commonly have some equipment for making minor

adjustments and small repairs, and chauffeurs are expected to keep their

automobiles in good running order. Public garages, which in many cases

are maintained in connection with automobile sales agencies, often

employ several general repair men, and sometimes employ starting,

lighting, and ignition specialists.

The repair shops are established principally for the purpose of

repairing and rebuilding all types of cars with their parts and

accessories. They offer a large field of employment for repairmen and

experts.

Service stations, often referred to as oil and gasoline filling

stations, include shops where special types of work are done. They may

be classified as battery, speedometer, ignition, starting and lighting,

and tire-service stations. Many men, if they have been trained, find

employment in these places.

Chauffeurs and truck drivers find employment in both private and public

service--chauffeurs in driving taxicabs and private pleasure

automobiles; and drivers in the operation of light and heavy delivery

trucks for retail and wholesale houses, and also in hauling materials

for road and building construction, farm produce, and manufactured

products.

Automobile plants and garages employ men as testers in the working out

of new cars, and for the purpose of locating and determining trouble

when a car is not working properly.

Finally, men with a knowledge of automobiles, parts, accessories, and

equipment can find employment as salesmen in garages, sales agencies,

and retail and wholesale stores.

PLAN No. 1152. AUTOMOBILE REPAIR-SHOP WORK

THE OCCUPATION

Repair-shop work consists in overhauling, adjusting, and repairing all

types of motor cars and their parts. In the small garages where only a

few men, often only one, are employed the mechanic must handle all kinds

of work. Some large garages, as has been noted, employ specialists, and

in many localities there are service and repair shops maintained

especially for this work.

Oxy-acetylene welding, a trade separate and apart from repair work,

which is used to a very large extent in the repairing and building up of

broken castings and forgings in automobile repair shops, is taken up in

another monograph.

In some shops there are enginemen, axlemen, transmission men, and other

mechanical experts. All of these may be classified as mechanics. Other

men found in repair shops are known as trouble-finders or inspectors,

helpers, foremen, and carburetor specialists.

The mechanic should be able to do skilled work on all mechanical parts

of any car. His work consists in adjustment, care, overhauling, and

repairing. Adjustment and care include valve, carburetor, clutch-spring,

brake, and steering-mechanism adjustment, and cleaning and lubrication

of parts. Much of this work can, however, be done by the automobile

driver or helper in a garage. Overhauling includes repairing, but refers

generally to the tearing down of the whole machine for cleaning,

inspection, adjustment, and testing, together with replacement of worn

and broken parts. Work on the engine requires in many cases its removal

from the chassis, and disconnection of all attached parts. Some of the

jobs to be done on automobile engines are removal of carbon from

pistons, refitting of pistons, regrinding valves, replacing and scraping

bearings, adjustment of fans and valve rods, setting timing gears,

correcting the firing order of cylinders, repairing and replacing broken

parts.

The mechanic is required to remedy clutch troubles, by adjustment or

replacing of worn leather on the cone. Transmission repairs include

replacement of gears, fitting keys, taking up the wear in the main

bearings, or complete replacement and repair of shifting-rod connections

to overcome looseness. The universal joints in driving mechanisms often

require disassembling and rebushing, while the mesh of the drive pinion

and bevel gear of the differential will need adjusting. Work on the

differential and rear axle may involve tearing down the rear

construction. Such work requires skilled mechanics, especially to

determine the trouble and make the proper reassembly. The play in wheels

needs careful attention and exact adjustment, although it requires no

particular skill or knowledge. Trouble found in the front wheels is

ordinarily due to lack of alignment, and must be remedied to relieve not

only a tremendous wear on tires but to prevent uncertain and difficult

steering. A sagging in the frame, often caused by a fracture, can best

be repaired by welding. Brakes require attention to eliminate noises

and dragging, which causes a noticeable lack of power, and worn brake

linings must be replaced.

The cooling system, made up of pump, fan, radiator, and connections,

will require adjustment and repair, including replacing the rubber hose,

mending broken parts of the pump, putting on new fan belts, and

soldering leaks in the radiator. Cleaning the radiator and taking

cold-weather precautions against freezing also are necessary tasks.

An inspector or trouble finder in a repair shop or garage service

department is the foreman or mechanic, but in large shops men are

employed solely for the purpose of diagnosing trouble. Such a man must

be highly skilled. His work is to locate trouble and determine and

report its nature and extent. Trouble is located by inspection and

examination of the car standing still, by testing at the start and at

various speeds, and by coasting. The trouble-finder expert makes a list

of all worn and broken parts, indicates necessary repairs and

adjustments, and then turns the job over to the men who are to do the

work.

Usually the foreman is in charge of all repair-shop work. He should be a

man of clean personal habits, should have a thorough knowledge of

automatic construction, and be able to direct work and handle men with

courtesy and tact, to compute jobs, estimate cost of time and materials,

keep time and stock records, and route work through on repair-order

forms specifying work, parts, and costs for each job. A manager or

superintendent often is in charge of the business end of the work, in

which case the foreman gives his time to seeing that jobs are correctly

done.

Helpers are usually assigned to heavy lifting and pulling, to cleaning

parts, and to general shop sweeping. They run errands, help pull down

and assemble motors, transmissions, and rear axles, and do other work

requiring little skill.

TOOLS, MACHINES, EQUIPMENT, AND MATERIALS USED

A variety of hand tools are used in repair work, including adjustable

and fixed jaw wrenches, hammers, snips, breast and hand drills, screw

drivers, hack saws, center punches, cold and cape chisels, soldering

coppers, pliers, files, brushes, blow torches, vises, and other small

tools. The machine equipment includes lathes, drill presses, grinders,

and forges equipped with motor power and having full sets of tools for

use with each. The shop must be further provided with benches, chain

hoists, motor and rear-axle stands, creepers, and special tools and

devices for special work. An oxy-acetylene welding and cutting outfit of

the portable type is one of the greatest conveniences in any repair

shop.

Most of the parts, supplies, and materials come to the shop prepared and

ready for use. For some jobs, however, it may be convenient and more

satisfactory to construct the necessary parts, such as shims, gaskets,

and small metal pieces, from stock material. It is inadvisable, however,

to make anything that can be secured already prepared.

Automobile repair-shop work is varied and interesting. Jobs frequently

change, with intervals of rest.

DISABILITIES

Hard and fast rules as to availability for this work of men with certain

disabilities can not be laid down. With perseverance, skill, and

inventiveness some men will succeed in lines of work which might seem

entirely unsuited to their disability. For example, a man who has lost

his right arm near the shoulder has been for 30 years doing successfully

all of the repair work and making all of the adjustments necessary on a

thrashing machine, a traction engine, 12 self-binding and 12 mowing

machines on a farm in England. An all-round mechanic must usually be

able to move about easily. He needs at least one good eye, and must be

able to hear well for trouble testing. A man with abdominal, kidney, or

alimentary canal trouble, which prohibits him from stooping, bending, or

squatting, can not do the work. Gas vapors, fumes, and dust in a garage

may affect men with lung diseases. It is very necessary for the worker

to have reasonably good command of neck and head movements.

APPLIANCES

Many devices and prosthetic appliances are in use in all countries by

men with arm amputations, and where previous experience, desire, and

conditions place a man in a position requiring the use of an artificial

appliance for gripping and holding tools one of strong and simple

construction should be selected.

PREVIOUS EDUCATION, TRAINING, AND EXPERIENCE

While general education will help a man in shop repair work, as in

anything else, it is more essential that he shall have had some

technical training acquired either in a school or in a shop. Previous

experience in automobile repair or construction work will, of course,

give the best foundation for re-education. A man who has worked as a

helper in a garage long enough to become familiar with automobile

construction and operation may through a short course of instruction

easily qualify as a mechanic. Experience in other mechanical work such

as machine-shop work, blacksmithing, and boiler making will be also

helpful. Business experience will be a valuable asset for a repair-shop

foreman or manager.

WHERE RE-EDUCATION WILL BE GIVEN

Full-time classes may be given in the shop of a high school, vocational

or trade school, college or university, where the equipment is

sufficient to provide for real instruction of a practical nature.

Re-education classes will be trained also in commercial garages under

actual shop conditions. Part-time classes providing alternate weeks or

months in the school and in the shop may be best in some cases, or the

first or last part of the training period may be spent in the shop and

the other part in school. For example, in an eight months’ course four

months may be spent in a commercial repair shop and the remaining four

months in a school shop.

Evening classes offer a splendid opportunity for the workman who is

employed during the day. These, of course, will be for those men only

who are able to return without re-education or for men who have finished

their re-education course and desire additional instruction.

Correspondence courses may be used in some instances.

WHAT CAN BE LEARNED AND IN WHAT TIME

Although theory and demonstration work will accompany the shop practice,

each man will be required to actually do the work. To say the least, the

course of instruction will be such as will enable the disabled man to

qualify on the job beside his able-bodied neighbor and to command the

prevailing wage after completing his course. His work will include the

overhauling, repairing, and adjusting of various makes and models of

automobiles and parts.

The time required to complete the course of instruction will depend to a

certain extent on the man’s previous education, training, and

experience, but may occupy from six to nine months. It will not be the

policy of the Government to give just enough training to enable the man

to secure a job under good but abnormal conditions or by sympathetic

favor. Sufficient time will be given to prepare each man adequately for

his work.

AFTER TRAINING--WHAT?

Skilled auto mechanics are in great demand, and since repair work is so

diversified and widely distributed over the entire country, it is

comparatively easy for a trained man to find permanent employment. Auto

mechanics as a rule are poorly trained. The trade therefore presents

excellent opportunities for the disabled man with expert training. The

field is also wide open for capable foremen and inspectors in every

community.

Hours of employment for the mechanic depend largely upon location and

amount of work to be done. Shops in large cities have an 8 to 10 hour

day, the total number of hours per week being 45 to 60. In small towns

and communities shops are irregular as to hours, mechanics being

required often to work 9 to 12 hours per day.

First-class mechanics in large shops are paid a prevailing wage of 60

cents per hour. Small shops pay from 30 to 60 cents. A mechanic who owns

his shop may earn more or less. Foremen employed by the hour usually

receive a little more than the mechanic, while in a position as shop

manager he may be paid $125 to $175 per month.

Automobile repair shops doing general work are located in all parts of

the country and usually in many different parts of a city. Work will

therefore probably be available for the trained man near his home or at

least in his home town.

An automobile mechanic may expect to secure a position as foreman or

inspector, which is often more suitable for a disabled man than that of

mechanic. Or he may be able to open up a garage and repair shop for

himself. Because of the increased use of automobiles and the lack of

first-class trained mechanics future prospects in the service are good.

QUALIFYING AS A TEACHER

Teachers for automobile work are in great demand at the present time in

both day and evening vocational schools. A man with a fair general

education, considerable experience in the trade, and ability to impart

knowledge to others, will have a good foundation for vocational

teaching.

ELECTRIC STARTING AND LIGHTING SERVICE

THE OCCUPATION

The principal parts of an electric starting and lighting system are the

electric starting motor, the electric generator, and the storage

battery. The work of the expert in this division consists of the repair,

adjustment, care, operation, and installation of these systems and

auxiliary parts, but usually not including the storage battery which

requires the individual attention of another specialist.

To keep the starting motor in good running condition the expert must be

able to remedy grounds, short circuits, and commutator and brush

troubles. The generator and all connecting parts must be kept clean in

order to insure reliable action. There are many types and varying

features in generators, motors, auxiliary devices, and wiring circuits,

with which the mechanic must be familiar. Automobile manufacturers in

altering the characteristics of their motors from year to year and

manufacturers of electrical apparatus in introducing various

improvements may entirely change their systems.

In addition to being able to locate trouble by tracing and testing

systems for grounds, shorts, and breaks in wiring, it is necessary for

the mechanic to install systems including all the wiring. He must be

able to repair and keep in shape electric horns and gear shifts which

are closely related to the starting and lighting systems. The wiring for

starting, generating, and lighting systems involves the installation of

all necessary wires, many of which must be run in conduit. It also

includes the use of proper sized wire and their connection to the

lights, starter, horn, fuse boxes, switches, generator, and battery. The

repair and adjustment of the lighting system require considerable expert

attention, as does also equipment of cars with lamp reflectors,

measuring instruments, and other devices.

TOOLS AND EQUIPMENT

All tools used in the maintenance and service of automobile starting and

lighting systems are small and light. They will include screw drivers,

wrenches, hammers, files, pliers, and various drilling tools. Some

machines may be required to make or fit metal parts, but as a rule they

will be found in the repair shop.

DISABILITIES

The work in this occupation is highly skilled but light. In working

around the car it is necessary to bend, stoop, reach, and climb, which

might be detrimental to a man suffering from abdominal trouble. The work

ordinarily requires two good hands, although a man with one hand with

the proper training and experience would be able to make repairs and

adjustments. Good eyesight is necessary in testing for trouble, but a

slight deafness will not be a serious handicap for this work. A man with

hernia or lung wounds and diseases would not necessarily be debarred

from this occupation.

PREVIOUS EDUCATION, TRAINING, AND EXPERIENCE

Practical experience and a technical knowledge of electricity will be

very helpful in electric starting and lighting work. Some of the best

men in the field have had considerable electrical experience in some

other field, many of them having been with telephone companies. A man

who thoroughly understands electricity will soon adapt himself to this

new field of work. A general education is always an aid, and

particularly so here where it will be necessary to do considerable

reading to keep pace with new improvements and developments in these

appliances.

WHERE AND WHAT EDUCATION WILL BE GIVEN

The re-education classes for training starting and lighting specialists

will be given in about the same type of schools as for repair-shop men.

It may also be advisable to train men in service or manufacturing shops.

The content of the course will cover the field of both theory and

practice in studying and working on motors, generators, and lighting

systems. That a man is fully qualified to go into a permanent position

will necessarily be shown by his ability to do the work. The time

required to finish the course will depend upon his previous experience

and training, but it will probably be from four to six months.

AFTER THE TRAINING--WHAT?

The demand for skilled specialists is increasing in all parts of the

country. This is true of any specialist in automobile maintenance and

service. Permanent positions will be available in all large

establishments and men employed in the smaller shops will be prepared to

handle other automobile work. The hours of employment will vary from 9

hours in large city shops to 10 or 12 hours in a shop owned by the

mechanic. The prevailing wage for this work will be about 60 cents per

hour.

Employment will no doubt be very stable both for the present and the

future. There is a lack of skilled specialists now, and with the

increased use of trucks and automobiles the demand will grow. The work

can be done in a good, light, dry shop, which will not be detrimental to

health. Because of the character of the work safety appliances are not

necessary, and danger from accidents of any kind is very small. The same

opportunity is open to these men for advancement and success as to the

repair-shop mechanic. They can become foremen, managers, or owners of

service and maintenance shops.

PLAN No. 1153. AUTOMOBILE IGNITION SERVICE

OCCUPATION

The ignition system is usually made up of certain electrical devices

which probably give more trouble to the auto man and require more expert

attention than all the other parts on the automobile. To be able to

diagnose a case and submit a remedy for ignition troubles, it is

necessary to be thoroughly familiar with the principles of ignition and

to understand how these ignition systems are operated and maintained.

Ignition primarily means igniting the gas in the cylinders of an engine

by means of an electric spark as the gas mixture is compressed. An

ignition expert should first of all have a practical knowledge of

electricity, know the meaning of electrical terms and the method of

generation and transmission of electric current. Of the two systems of

ignition, high and low tension, the high-tension system is now in use in

nearly all makes of motor cars. The low-tension system was formerly used

to a great extent on boat engines, and is used now to some extent on

stationary engines.

The ignition mechanic deals with the testing, adjustment, and

maintenance of current supply, vibrators, coils, commutators and timers,

contact breakers, spark plugs, condensers, distributors, magnetos, and

connectors. He must be thoroughly familiar with wiring systems and their

connections. Spark plugs will have to be cleaned, adjusted and repaired,

as will the vibrators when they are used. Ignition timing to insure

ignition at the right time requires special attention. The care,

installation, and maintenance of magnetos, which brings in the proper

firing order of the engine, care of the distributor, and attention to

connections, is one part of the ignition expert’s task. The field of

ignition trouble may be covered under three heads: (1) Failure of

current supply, (2) short circuits or grounds, (3) failure of ignition

devices. To keep the ignition system in good working order it is

necessary to locate trouble and make repairs as indicated.

TOOLS AND EQUIPMENT

Because of the many small and complex parts ignition systems require

delicate attention. This involves the use of small hand tools only, such

as will be used by the electric starting and lighting experts. Although

it will be necessary to make certain repairs to broken and worn parts,

it is customary to replace with new parts.

DISABILITIES

The work of the ignition expert is very much like the work of the

electric starting and lighting expert. Bench repairs to magnetos and

other devices can be made by a man whose disability requires him to sit.

The work is not strenuous and consequently could be done by men with

lung disease, hernia, and abdominal troubles, except where it is

necessary to stoop or bend over the job, as would be necessary in

testing for trouble and making connections in the installed system.

Because of the delicate work, a mechanic’s eyesight must be good, but

poor hearing would not debar a man from this occupation. It is quite

necessary for the workman to have good use of his hands and fingers.

PREVIOUS TRAINING AND EXPERIENCE

The same training and experience helpful to the electric starting and

lighting expert would aid the man in training for ignition work. A man

who has been employed previous to army service in any electric work,

such as telephone and telegraph installation and maintenance, or the

making of electric motors and devices, would have acquired electrical

experience which would be of great help to him in this work.

WHERE AND WHAT EDUCATION WILL BE GIVEN

The classes for ignition mechanics will be carried on in both schools

and shops. The time will probably be divided between theory and shop

practice. The proper equipment and practical jobs will be available for

teaching the man to do the work.

The course will be from four to six months in length for about seven

hours per day for five days in the week. Instruction will include all

problems requiring attention of the commercial ignition shop.

AFTER THE TRAINING--WHAT?

The demand for the ignition expert is equally as great as for any other

automobile specialist. His services are required in garages and service

stations, as well as in assembly plants, and in the driving and

operation of motor cars and trucks. The hours of employment are the same

as in other auto repair shops, usually eight hours per day for union

shops, and longer in small unorganized shops and where the mechanic owns

his business.

The prevailing wage is 60 cents per hour, although this may vary from 30

cents to 75 cents per hour, depending upon labor conditions and methods

of employment. It is probable that ignition experts will be employed

only in the larger places, but it is necessary to have expert ignition

service in any shop. This is in small shops usually taken care of by the

repair-shop mechanic who has a general knowledge of the automobile

maintenance and service. Employment for the trained man will be stable.

Ordinarily only the better class of mechanics, those with special

training are retained during the winter season, when the overhauling of

cars is done. The rush season from spring to fall gives employment to a

number of “roustabouts” or helpers, but these “floaters” require no

special training.

Promotion and success will depend largely upon the ability of the

mechanic, but it is possible for him to advance to positions of

responsibility, carrying increase of wages. The field is large and

skilled mechanics are scarce, thus making it possible for the trained

man to find suitable employment and to make changes for promotion.

PLAN No. 1154. STORAGE BATTERY REPAIRMEN

OCCUPATION

The sources of electricity for ignition, starting, lighting, warmers,

horn, shifting gears, and application of brakes in some instances are

the generators and battery. They must furnish the power. The generator

produces electricity only while the engine is running, and the demands

on it are comparatively light and simple. The battery must furnish power

to crank the engine, to light the car, operate the horn and other

electrical devices when the generator is not in motion. It is without

doubt one of the most essential and necessary parts of the automobile.

To be a thorough master of battery problems a knowledge of both

electricity and chemistry is necessary.

A general knowledge of batteries includes the method of construction and

the materials used in the manufacture of batteries. Chemistry deals with

the actions producing electricity and aids in determining the reasons

and remedy for trouble. The expert must know what happens in a battery

standing idle, just what takes place in the charging and discharging,

and what determines the capacity of batteries. A knowledge of battery

diseases will help a man very materially in the proper diagnosis of

battery trouble.

The shop work of the battery man includes caring for, charging, lead

burning, and rebuilding batteries. Caring for batteries includes keeping

the plates covered with distilled water, brushing dirt and dust from the

top, keeping cables and connections tight, cleaning battery terminals

and connections and carefully inspecting and testing it frequently.

Charging consists, figuratively, in feeding it electricity, which when

digested gives it energy. It is necessary for the battery man to be

thoroughly familiar with the charging apparatus and able to operate it

successfully. Lead burning is a process of melting together the plates

and straps or posts and top connectors and terminals with a special

lead-burning outfit. In rebuilding a battery, it is first charged, then

opened and torn down, after which the plates are repaired or replaced,

assembled with the proper separators, replaced in the jars, and then

carried through the charging process. The covers are next put on and

sealed.

TOOLS AND EQUIPMENT

The room for battery work should have a floor such as tile or brick, not

easily affected by acid. The equipment ordinarily includes work benches,

vises, a lead burning outfit, water supply, charging benches and

equipment, shelves, and stoves. Proper tools, including brushes,

scrapers, pliers, nippers, files, hydrometers, putty knife, wrenches,

brace and bit, stock drills, center punches, hack saws, kettles, ladles,

jars, screw drivers, materials and other hand tools are provided. The

work is practically all hand work and consequently requires hand tools.

DISABILITIES

Battery work requires the use of two hands. The loss of three fingers

from one hand would not seriously impair efficiency if some grip with

the remaining finger and thumb is retained. In the use of pliers, screw

drivers, brace and bits, and other tools it is necessary to hold them

firmly. Hearing is not particularly essential, but good eyesight is

necessary. Stooping, bending, and lifting the weight of a battery would

not affect men with slight hernia and abdominal trouble. A man with

artificial legs should be able to do the work if he can get around

without great difficulty.

Danger from lead poisoning and acid burns and fumes is prevalent in

battery work, but occurs only through carelessness. A man with any skin

or lung diseases or wounds probably should not undertake this work.

Gloves are worn in handling lead, but they will not protect against skin

wounds. The eyes may be injured by lead and acid, but by wearing goggles

this can be avoided. A man with any open wounds should not enter battery

service work.

SPECIAL APPLIANCES

No special appliances can be arranged satisfactorily to handle the tools

and equipment, although stools can be provided for the man who is

required to sit.

PREVIOUS EDUCATION AND EXPERIENCE

A knowledge of chemistry and work in a chemical laboratory will help a

man to become a battery expert. Experience in battery construction and

in the care of starting and lighting batteries will also be an excellent

start, as would experience as a helper in a battery-service station.

WHERE AND WHAT RE-EDUCATION WILL BE GIVEN

To a large extent the instruction in battery work will be carried on in

a service station where equipment is available. A school shop properly

equipped will also be made use of.

The course will contain the elements and fundamentals of battery

maintenance and service. The length of the course will be from 4 to 6

months.

AFTER THE TRAINING--WHAT?

Permanent positions as battery experts will be open in battery-service

stations. The knowledge will also be necessary for the man who proposes

to set up a shop of his own. It is a general condition that battery work

be done in an independent and separate shop rather than in a general

repair shop. The hours of employment will not vary from those already

given for other types of maintenance and service work, and the wage will

also be about the same.

In cities and towns of 5,000 or over there will be found work enough for

one or more battery stations employing two or more men. Employment will

invariably be stable for the highly skilled battery expert. Opportunity

for promotion and success will depend upon the man, but there is great

demand for expert service, and there is a good field in many places for

the establishment of service stations. Future prospects are exceedingly

good due to the large increase in the use of storage batteries. It is

also true that the average automobile driver and owner is waking up to

the fact that the battery must have special care and repair to keep it

in good working shape.

PLAN No. 1155. TIRE REPAIRING

THE OCCUPATION

The repair of automobile tires, including casings and tubes, is almost

invariably assigned to a specialist, although many of the minor repairs,

such as patching tubes, are done by owners or amateur repairers. Tires

are probably the most delicate and the most misunderstood part of the

car, as well as being the part receiving the hardest use. To secure the

greatest mileage and the least trouble from tires they must receive

proper treatment and have the attention of a specialist when trouble

develops.

The tire repairman should have a knowledge of tire construction and be

well versed in tire troubles and their causes in order to make proper

diagnoses of the cases. This knowledge is necessary also in making

adjustments on tire mileage, which is, in connection with the tire sales

agency, a business very often established as an adjunct to the repair

business.

The shop work of the repair man deals with casing troubles from

punctures, blow-outs, rim cuts, blisters, stone bruises, and with the

preparation of the tire for repairing, relining, retreading, and

vulcanizing. Tubes have to be patched, spliced, and vulcanized. Valves

in the tube stem will often cause trouble by leaking, but can be

remedied by replacing with new valves. Sand blisters can be cured by

opening the blister with a sharp knife, cleaning out the dirt and

filling the hole with a self-curing rubber filler. A blow-out caused by

a weak place in the casing usually due to a sand blister or stone

bruise can be remedied by the inside method or a combination inside and

outside method. Both methods consist in removing layers of fabric and

applying fabric patches. When the outside has been properly built up

with fabric and the chafing strips applied the cushion gum unit can be

applied and the whole casing then placed in a sectional mold, where heat

applied to both the inside and out will cure the job. Rim cuts are

repaired in a similar way. Retreading is done by first cleaning down to

the carcase and applying coats of vulcanizing cement upon which the

tread can be built up and vulcanized. Reliners are vulcanized to the

inside of a casing to take care of inside fabric breaks.

The work on the inner tube consists in patching to cover small holes,

cuts, pinched tubes, and minor injuries.

Vulcanizing, which should be done on large patches, is also the best

remedy for any repair. It is done by first cleaning the hole, preparing

the patch, and placing and vulcanizing. Inserting new sections or

splicing tubes is done by removing the damaged section, inserting a new

one, and vulcanizing, one splice being made at a time.

TOOLS AND EQUIPMENT

The equipment of a tire repair shop contains vulcanizers of many sizes

which apply the heat through the use of gasoline, steam, or electricity.

Vulcanizing moulds which are made to fit the tire are necessary for

applying casing patches. Vulcanizing kettles, sidewall and retreading

vulcanizers, benches, vises and holding forms are also to be found. The

small tools required include flat and concave rollers, awls, stickers,

rubber knives, large shears, wire brushes, tread gauges, fabric knives,

pliers, scrapers, tread chisels and cement brushes. Splicing mandrels,

try squares, tweezers, rules, spreaders and other devices and tools may

be found in the equipment.

DISABILITIES

The work in a repair shop is not very strenuous, although it requires

careful attention and speed. It is necessary that the man have the use

of both hands and be able to see his work clearly. Deafness will not

interfere to any great extent with his success. Lifting, stooping, or

bending, while necessary to a small degree, is not common. The weight of

a tire is the heaviest weight to handle around the shop.

There is little danger from poisoning or injury to skin, except as

infection may be brought in with dirt on the tires. A man with leg

disabilities will certainly not be debarred from this occupation if he

can get around without great difficulty. It is possible to do some of

the work while seated. A man having lost the use of certain neck

movements would be able to handle tire repair work.

PREVIOUS EDUCATION AND EXPERIENCE

A general education will be of much help in handling the business end of

the shop, while technical knowledge of automobile tires will be a good

basis for repairing. Experience in a tire manufacturing plant or rubber

industry, and in a repair shop as a helper will be very valuable to a

man entering this field.

WHERE AND WHAT RE-EDUCATION WILL BE GIVEN

Classes for tire repairmen will be carried on in schools where equipment

is available, but probably to a large extent in the commercial repair

shop where actual working conditions exist. Both full-time and part-time

schemes may be used.

The course will include practical work on all kinds of repair jobs.

Tires will be studied to help a man to determine the cause and remedy of

tire trouble and to make adjustments. The time necessary to qualify as

an expert tire repairman will be from 4 to 6 months.

AFTER THE TRAINING--WHAT?

Employment in tire repair shops for a skilled man will be easily found.

The field is large and shops are required in nearly every village, town

and city. With the increased use of cars the year round will come

increased demand for tire repair service and hence year round employment

for the tire specialist. The daily hours of work will be from 8 to 10

depending upon local conditions.

The wage of the skilled workman will be about 60 cents per hour, but a

man owning his business can make it more profitable. Opportunity for

promotion will come through increase of the man’s own business, or

through advancement to the position of foreman or manager in a large

shop.

PLAN No. 1156. AUTOMOBILE AND TRUCK DRIVERS

THE OCCUPATION

Chauffeurs and motor-truck drivers are employed to drive cars and keep

them in good running condition. It is very essential that anyone

operating a car shall know its construction and the function that each

part performs. He should know how to care for the machine and how to

make minor adjustments. Lubrication of all parts properly at regular

intervals is an important task of the driver. The location of trouble

and the detection of its cause and remedy is even more important than

driving upon the highway.

The operation of the car includes starting and stopping the engine,

starting and stopping the car, and driving. One of the first things to

know is how to stop the car. The use of the emergency and service

brakes, as well as braking with the engine, requires considerable skill

and experience. Cranking and starting apparatus must be understood if it

is to be used with ease and without injury. Skill in shifting gears and

in controlling the car is attained by experience.

A good driver must have a knowledge of road regulations and precautions,

and must also be familiar with city ordinances in regard to the driving

and parking of automobiles. He must be cautious, able to see danger, and

to avoid it.

TOOLS AND EQUIPMENT

An automobile should always be equipped with a complete set of tools for

making repairs and adjustments. A tire repair outfit is a valuable

addition to the driver’s equipment. The tools and equipment are of the

portable type, easy to manipulate, and convenient to carry around.

DISABILITIES

A chauffeur or truck driver should have good eyesight and be able to

hear distinctly. It is necessary to locate trouble and remedy it by

seeing or hearing. Danger is averted by carefully watching the road and

things likely to interfere with travel, and also by listening for

approaching trains and cars.

A man in this employment should have two hands, although he might have

lost some of his fingers. It is also well for him to have the free use

of his arms and legs. A man with leg amputation below the knee would be

able to operate the brakes, clutch, and accelerator without difficulty.

Lung diseases and wounds, hernia, and abdominal trouble would not debar

a man from work of this kind. It is necessary that he be able to have

the full use of his neck and head. A man suffering from shell shock, who

is subject to nervousness, loss of memory, or inability to control his

actions should not be employed as a chauffeur.

APPLIANCES

A man so disabled that he must have special devices or appliances to

operate an automobile should not enter the occupation. Artificial legs

which can be properly controlled would not, however, debar him.

PREVIOUS TRAINING AND EXPERIENCE

A man who has had experience in operating or repairing automobiles,

motor boats, motorcycles, or gas engines will have some knowledge

necessary for chauffeurs and motor-truck drivers. A man with ability

along mechanical lines and training, also, enabling him to learn the

principles of motor-car operation and care readily will have a good

foundation for this occupation.

WHERE AND WHAT RE-EDUCATION WILL BE GIVEN

Classes for motor-car care and operation will be conducted very largely

in schools having the necessary space and facilities for work.

Instruction will include class-room instruction and study, shop-repair

work, and driving. Operation instruction will be conducted on the road.

The course will be arranged to prepare a man adequately for successful

motor-car care and operation. He will have an opportunity to come in

contact with all problems usually confronted by the automobile and truck

driver. It will require from two to four months to complete the course,

depending upon the man’s previous experience and ability.

AFTER THE TRAINING--WHAT?

Good automobile and truck drivers are in demand. It has been predicted

that many of the truck drivers now in Government service will take

positions of that type after the war. This condition would probably

cause an excess of men for this work, and it is well to say that the men

who have the best training and qualifications will ordinarily secure the

positions.

The hours of employment will depend upon the man’s position but usually

the time is 8 to 12 hours per day. Drivers of pleasure cars are employed

for a greater number of hours usually, but much of the time while on

duty they are idle. Men in these jobs are paid at the rate of $10 to $35

per week.

Work as driver of light or heavy trucks and pleasure cars is available

in nearly all towns and cities. Employment is stable, except for the

fact that the cars may be out of use during the season of snow. The work

is healthful, inasmuch as the men are out in the air most of the time.

Severe weather may cause inconvenience and hardship to some people.

There is very little opportunity for promotion, except that gained

through changing jobs.

PLAN No. 1157. CONCRETE CONSTRUCTION AND CEMENT MANUFACTURE

ACKNOWLEDGMENT

This monograph was prepared by A. J. R. Curtis, of the Portland Cement

Association, under direction of Charles H. Winslow, Chief of the

Research Division of the Federal Board for Vocational Education.

Acknowledgment is due to Dr. John Cummings, of the Research Division,

for editorial assistance.

Development in the field of concrete construction during the past two

decades has been little short of marvelous. This increase may be

accredited to the wide variety of uses to which concrete may be put and

to the demand on the part of the American public for construction that

is permanent, reasonable in cost, and fireproof. The concrete industry

has brought in to the field of labor a new type of skilled workmen and

its varied phases each call for men with distinct, definite training.

Indications point to a greatly increased demand for men in this line of

industrial activity. If the increase in the production of Portland

cement during the last few years is reviewed one can easily see the

constantly increasing importance with which concrete construction is

being regarded. The shipments of cement leaped from 8,000,000 barrels in

1900 to 92,000,000 in 1917. A vivid imagination will not be needed to

picture a still greater and wider field for its use in the future.

With the cessation of hostilities new construction work of many kinds is

being planned in every section of the country. Millions of dollars will

be spent for new buildings, highways, bridges, and various other types

of public and private improvements. There will be a demand for trained

workmen which will probably tax every effort to supply. A large

percentage of the occupations in this line of work can be filled

efficiently by men who have suffered some disability in the service of

their country. The handicap in the loss of a leg or an arm on the

battlefields of France can be overcome with the aid of a “Made in

America” leg or arm, fitting the wearer to fill efficiently many

occupations in the concrete industry.

A careful study has been made of the limitations imposed by various

injuries. There are many cases on record where injured men have overcome

all handicaps and have made good in positions which from the survey of

the re-educationist appeared quite impossible. Many instances have come

to light which show that the statement, “A handicap is merely a state of

mind,” holds true for a great variety of cases.

The wage question is no doubt one of the first which arises in your

mind. It is natural that one should ask, “What wages or salary does this

job pay?” and, “What are the chances for advancement?” In a review of

the wages of men engaged in concrete construction as compared with the

men engaged in other lines of construction work this fact was noted,

that although in 1913 the average wage for the concrete worker was

somewhat lower, during the year 1916 wages for concrete workers advanced

60 per cent while for workers in the other line the advance was only 20

per cent. For the man with training in this work the salary will average

near $150 per month. As regards opportunities for advancement, few other

lines of activity seem to hold forth comparable opportunities, when it

is considered that a large proportion of competent workers eventually

become partners or managing owners in contracting concerns, while the

demand for construction superintendents is usually greater than the

supply.

For convenience, concrete-work employments may be classified in three

distinct groups, namely: (1) Structural group, including the building of

reinforced concrete structures, ships, bridges, dams, retaining walls,

and a multitude of small structures; (2) roads and highway group,

including the construction of concrete roads and highways, pavements,

and alleys; (3) products plant group, including the making of blocks,

brick, tile, sewer and pressure pipe, and ornamental trim work.

PLAN No. 1158. STRUCTURAL GROUP

ENGINEER OR ARCHITECT

In large structural work the man in charge is usually a civil engineer

or an architect, who has specialized during his course of training in

structural or reinforced concrete engineering. He is the designer or the

creator of the proposed structure. Before any work is done he must

picture in his mind the finished product in every detail of its

construction; he must be able to design and lay out the plans for the

work in its entirety; he must be familiar with the cost of labor and

materials, in order that he may know when the contractor is placing a

fair price upon the construction. He must know the building laws and

codes in any part of the country in which he may be working. He should

have business training and experience, as practically all his

associations will be with business men, and he must be able to talk

intelligently and in business terms to them.

A large percentage of his time will be spent in the office or designing

room.

His training is received in one of two ways, namely: By full-time course

of training in the civil engineering department of a university or

college, or by part-time study in a technical school. Many schools of

this last-named type are now giving evening work, which enables young

men to attain the degree of a civil engineer or architectural engineer

while working. Thus, a man who is working during the day, may increase

his efficiency and attain the same end as his brother, who has been more

fortunate in that he has received a full four years’ training.

To reach the position of engineer architect, the training described

above is an absolute necessity. As a usual thing a civil engineer who

has just completed his course starts work in the capacity of draftsman,

foreman, inspector, or assistant superintendent, and as he gains in

experience is given more responsible positions. His wages range from

approximately $100 at the start to $400 or $500 per month as he gains in

efficiency and experience.

Often, after gaining experience an engineer will establish a clientage,

and gradually work up a business of his own. This is a goal toward which

to strive, as it means greater independence and a larger income. His

services are in demand in every part of the country the year round.

PLAN No. 1159. INSPECTOR

After designing a structure the engineer lets the job of constructing to

a contracting firm. He places as his representative on the job an

inspector whose duty it is to see that the engineer’s plans and

specifications are properly carried out. The duties of an inspector are

not difficult, but it takes a man with diplomacy and consideration, yet

one who is sufficiently firm to safeguard his employer’s interests and

make sure that every part of the work is performed in a thoroughly

acceptable manner. It goes without saying that he must be acquainted

with every feature of the construction work as planned by the engineer.

His training is practically the same as that of the engineer or

architect. However, it is possible for a man who can not complete his

entire training at one time to accept a position as inspector, and gain

some very valuable experience in this way. There are also men who work

up from the ranks to this position. The demand for his services is

greatest in connection with large industrial and public projects and in

the general construction work in cities. His wages range from $100 to

$200 per month.

PLAN No. 1160. CONTRACTOR

The contractor or firm of contractors are equipped to handle the

construction work. At such a time as the engineer or architect has his

plans completed he advertises among the contractors for bids on the

construction according to his plans. As a rule the responsible firm

making the lowest bid gets the job.

PLAN No. 1161. SUPERINTENDENT

The first thing the contractor does after accepting the job is to select

a superintendent of construction. Superintendents are usually engineers

who have grown up in the service of the firm. The successful

superintendent must have resourcefulness, technical knowledge, tact,

energy, honesty, and judgment. He must have a personality which drives

to activity several hundred originally unorganized men who are without

special interest in the company they work for or in the results

accomplished, and with tact and judgment he must weld them into a

unified working organization, cheerful and self-respecting, with a high

morale and finally with enthusiasm for the work at hand. He must be able

to build in full size, with permanent materials, a structure the design

of which troubled the engineer or architect to show clearly on paper; he

must be honest, since his company must leave their reputation in his

hands and trust him with funds; he must, through attention and

experience, be so trained that dangerous operations are carried on as a

matter of routine without worry either to himself or his company; he

must have ability to foresee and provide for the problems which are

perhaps to come up months later; he should have his temper continually

under control, even under the most provoking circumstances; he should

have as much pride in the structure he is erecting as the engineer who

designed it; he must be able to handle labor and cope with the various

labor problems that may arise.

His training is practically the same as that of the engineer or

inspector, but he has been fitted by experience for the position of

superintendent. He may have served in various capacities with the same

contracting firm or with other firms. In some cases men with

extraordinary ability have worked up from the ranks by hard work and

home study or night-school training. The salary of the superintendent

varies in different localities and upon different jobs. It usually

ranges from $150 per month upward.

PLAN No. 1162. ASSISTANT SUPERINTENDENT

On the larger jobs the superintendent has an assistant. His duties are

dependent largely upon the man under whose direction he may be working.

From a study of the duties and qualifications of the superintendent an

idea may be gained of the nature of the assistant’s work. The

educational requirements are the same as those for the superintendent,

but his responsibility is less and therefore as great and varied

experience is not required. The opportunity for his services depends

upon the number of large jobs under construction. His salary usually

ranges from $100 to $200 per month.

PLAN No. 1163. TIMEKEEPER

On all large jobs a timekeeper has a position of responsibility. His

duties are clerical in nature; in fact he might be called the

superintendent’s clerical assistant. As his name implies he is keeper of

the time of the men, and each day checks up the men on the job in order

that no mistakes may be made in figuring their time. He handles a large

amount of clerical work in connection with the pay roll, and may also be

called upon to do other work in connection with construction. He must be

a man who is absolutely honest and trustworthy. He has a wonderful

opportunity for observation and study of construction operations, and

can by application and study advance to a position of greater

responsibility and trust. His wage varies somewhat, and is dependent on

the amount of responsibility placed upon him and of work required of

him. Experience is of secondary importance.

PLAN No. 1164. FOREMAN

On a large job there will be several foremen, usually a general foreman,

a concrete foreman, foreman of reinforcing placing, and a

carpenter-foreman.

First and most important a foreman must be able to _handle men_. His

duties are more than just to hire and fire. He must be acquainted with

the problems of his men and spend some time studying their viewpoint of

all questions in which they may be interested. As he is ofttimes a man

who has advanced from the ranks by hard work, study, and superior

ability, he will be acquainted with the men’s side of the various labor

questions. However, he must be fair minded and not see the viewpoint of

the men alone, but must regard that also of his employer. He must be

able to weigh carefully any situation, and to make a fair and just

decision.

He must be able to read designs and put them into operation. He may not

be called upon to perform actual mechanical operations, but he must be

able to tell and to show his men how the work is done. He is, in fact,

the superintendent’s right-hand man on the particular portion of the

work which has been assigned to him. All of his time will be spent out

in the open upon the job. Wherever there are concreting operations in

progress, there you will find him.

The general foreman has active charge of all operations. The other

foremen, as a rule, come directly under his jurisdiction.

The concrete foreman has charge of all concreting operations; the

reinforcing foreman has charge of the placing all reinforcing; and the

carpenter foreman has charge of the building of the forms and erecting

of all staging and hoist towers necessary for carrying on the concreting

operations.

Generally speaking, the foremen gain their training from experience and

study; night schools have been started in some of the cities of the

country, which are giving courses in concrete work, particularly for the

man who is anxious to better his position.

PLAN No. 1165. FINISHERS

The repairing of imperfections in the concrete surfaces and the

finishing or floating of flat surfaces requires the work of the

finisher. He must possess manual dexterity so that he can handle a float

skillfully and must know when a surface has been worked sufficiently.

Skill is also required in pointing up or repairing imperfections in

surface from which forms have been removed. His wages range from 50 to

60 cents per hour. His training is received on the job.

PLAN No. 1166. MIXER OPERATOR

Several things are required of a mixer operator. First he must have some

mechanical skill and be able to handle and to take care of a steam or

gas engine or an electric motor. He should be able to repair the mixer

in case of a breakdown. He must also know something of proportioning and

of consistencies required for different mixtures and under different

conditions. Wherever any considerable amount of concreting is done the

services of a mixer operator are required. The wages are practically the

same as for finishers. His training is gained through experience on the

job.

PLAN No. 1167. FORM BUILDERS

Form builders are carpenters and must have the experience and training

required in that trade.

PLAN No. 1168. REINFORCING PLACERS

Reinforcing placers are very often laborers under the direction of a

skilled foreman. Their duties are to place the reinforcing steel

according to the specifications prepared by the engineer. In some of the

larger cities the Structural Steel Workers’ Union requires that all

placing of reinforcing be done by men from their union. The wages vary

according to locality. Very little training or experience is necessary.

PLAN No. 1169. RURAL CONTRACTORS

Rural contractors comprise a very numerous group, handling concrete jobs

in the smaller cities and towns throughout the country. Endowed with an

ordinary amount of business judgment, the rural contractor usually

becomes a well-to-do business man. He usually acts as his own

superintendent directing his jobs personally. The average rural

contractor is independent and commands the respect of the business men

of his community. His income is variable but always affords a good

living if his business is well managed. His income is often comparable

with that of the larger merchants in the community.

ROAD AND HIGHWAY GROUP

A large number of the occupations in this division are analogous to the

positions in the structural division.

PLAN No. 1170. ENGINEER

On practically all public highways the outlining of the plans and

specifications are left to the county or state highway engineer. His

course of technical training should include specialized work in highway

engineering. He must be thoroughly reliable and of unquestionable

integrity, as his judgment in matters pertaining to the construction of

highways and roads must be faultless.

Only recently the states of Illinois and Pennsylvania voted enormous

bond issues to be used in the construction of permanent hard-surfaced

roads. Many other states are planning to appropriate huge sums for the

same purpose. Never before has the opportunity for the highway engineer

been so great. The training required and the salary paid are very

similar to those of the structural engineer.

PLAN No. 1171. INSPECTOR

As in structural work the building of highways is usually let to a

contractor and the engineer places an inspector as his representative on

the job. The duties of the inspector are practically the same as upon

structural work.
