CHAPTER XV.

_EXAMPLES IN ENGINE WORK._

In the figures from 308 to 328 inclusive are given three examples in

engine work, all these drawings being from _The American Machinist_.

Figures 308 to 314 represent drawings of an automatic high speed engine

designed and made by Professor John E. and William A. Sweet, of

Syracuse, New York. Figure 308 is a side and 309 an end view of the

engine. Upon a bed-plate is bolted two straight frames, between which,

at their upper ends, the cylinder is secured by bolts. The guides for

the cross-head are bolted to the frame, which enables them to be readily

removed to be replaned when necessary. The hand wheel and rod to the

right are to operate the stop-cock for turning on and off the steam to

the steam-chest.

The objects of the design are as follows: Figure 310 is a vertical

section of the cylinder through the valve face, also showing the valve

in section, and it will be seen that the lower steam passage enters the

cylinder its full depth below the inside bottom, and that the whole

inside bottom surface of the cylinder slopes or inclines towards the

entrance of this passage. The object of this is to overcome the

difficulty experienced from the accumulation of water in the cylinder,

which, in the vertical engine, is usually a source of considerable

annoyance and frequently the cause of accident.

Any water that may be present in the bottom finds its way by gravity to

the port steam entrance, and is forced out by and with the exhaust steam

at or before the commencement of the return stroke.

To assist in the escape of water from the top of the cylinder, the

piston is made quite crowning at that end, the effect of which is to

collect the water in a narrow band, instead of spreading it over a large

surface. This materially assists in its escape, and at the same time

presents a large surface for the distribution of any water that may not

find its way out in advance of the piston.

The piston is a single casting unusually long and light, and is packed

with four spring rings of 3/8 inch square brass wire.

The valve is a simple rectangular plate, working between the valve face

and a cover plate, the cover plate being held in its proper position,

relative to the back of the valve, by steam pressure against its outer

surface, and by resting against loose distance pieces between its inner

surface and the valve seat. This construction admits of the valve

leaving the seat, if necessary, to relieve the cylinder from water, as

in the instance of priming, and also, by the reduction of these pieces,

admits of ready adjustment to contact, should it become necessary.

[Illustration: Fig. 311--VALVE MOTION.]

The cover plate is provided with recesses on its inner surface which

exactly correspond with the ports in the valve face, and the

corresponding ports and recesses are kept in communication with each

other by means of relief passages in the valve. From this it will be

seen that the valve is subjected to equal and balanced pressure on each

of its sides, and hence, is in equilibrium.

The valve is operated through the valve motion, shown in Figure 311, the

eccentric rod of which hooks on a slightly tapered block that turns on

the pin of the rock arm, like an ordinary journal box.

The expansion, or cut-off, is automatically regulated by the operation

of the governor in swinging the slotted eccentric in a manner

substantially equivalent to moving it across the shaft, but is however

favorably modified by the arrangement of the rock arm, which, in

combination with the other motions, neutralizes the unfavorable

operation of the usual shifting eccentric, and which, in connection with

the large double port opening, provides for a good use of steam from 0

to 3/4 stroke.

The governor shown in Figure 312 is of the disc and single ball type,

the centrifugal force of the ball being counteracted by a powerful

spring. Friction is reduced to a minimum in the governor connection, by

introducing steel rollers and hardened steel plates in such a manner as

to provide rolling instead of sliding motion.

In order that a governor shall correctly perform its functions, it is

unquestionably necessary that it have power largely in excess of the

work required of it, and also that the friction shall represent a very

low percentage of that power. In respect to this, especial means have

been employed to reduce the friction; the valve being balanced,

requires but little power to move it, while the governor ball being made

heavy for the purpose of counterbalancing the weight of the eccentric

and strap, its centrifugal force when the engine is at full speed is

enormous, the spring to counteract it having to sustain from _two to

three thousand pounds_. Under these circumstances, as might be expected,

the regulation is remarkably good. This is a very important

consideration in an engine working under the conditions of a roll-train

engine.

[Illustration: Fig. 312--GOVERNOR.]

[Illustration: Fig. 313--SECTION OF PILLOW BLOCK.]

Figure 313 represents a section of the pillow block box, crank-pin and

wheel, together with the main journal. It will be seen that the end of

the box next the crank wheel has a circular groove around its outside,

and that a corresponding groove in the crank wheel projects over this

groove. From this latter groove an oil hole of liberal size extends, as

shown, to the surface of the crank-pin. Any oil placed at the upper part

of the groove on the box finds its way by gravity into the groove in

the crank wheel, and is carried by centrifugal force to the outside

surface of the crank-pin; so that whatever other means of lubrication

may be employed, this one will always be positive in its action. This

cut also shows the manner in which the box overlaps the main journal and

forms the oil reservoir.

[Illustration: Fig. 314--CONNECTING ROD. (Page 295.)]

Another feature in the construction of this box is the means by which it

is made to adjust itself in line with the shaft. It will be observed

that it rests on the bottom of the jaws of the frame on two inclined

surfaces, which form equal angles with the axis of the shaft when in its

normal position, and that by moving longitudinally in either direction,

as may be necessary, the box will accommodate itself to a change in the

alignment of the shaft. In order that it may be free to move for this

purpose it is not fitted with the usual fore and aft flanges. By this

means any slight derangement, as in either the outboard or inboard

bearing wearing down the fastest, is taken care of, the movement of the

box on the inclined surfaces being for this purpose equivalent to the

operation of a ball and socket bearing.

Figure 314 gives a side and an edge view of the connecting rod, the rod

being in section in the edge view, and the brasses in section lined in

both views.

The cross-head pin, it will be observed, is tapered, and is drawn home

in the cross-head by a bolt; the sides of the pin are flattened somewhat

where the journal is, so that the pin may not wear oval, as it is apt to

do, because of the pull and thrust strain of the rod brasses falling

mainly upon the top and bottom of the journal, where the most wear

therefore takes place. The brasses at the crossed end are set up by a

wedge adjustable by means of the screw bolts shown. The cross-head wrist

pin being removable from the cross-head enables the upper end of the rod

to have a solid end, since it can be passed into place in the crossed

and the wrist pin inserted through the two. The lower ends of the

connecting-rod and the crank-pin possess a peculiar feature, inasmuch as

by enlarging the diameter of the crank-pin, the ends of the brasses

overlap, to a certain extent, the ends of the journal, thus holding the

oil and affording increased lubrication. The segments that partly

envelop the cross-head pin and crank-pin, and are section lined in two

directions, producing crossing section lines, or small squares, show

that the brasses are lined with babbitt metal, which is represented by

this kind of cross-hatching. These drawings are sufficiently open and

clear to form very good examples to copy and to trace on tracing paper.

[Illustration: Fig. 315.]

[Illustration: Fig. 316. (Page 296.)]

[Illustration: Fig. 317.]

Figures 315, 316 and 317 represent, in place upon its setting, a 200

horse-power horizontal steam-boiler for a stationary engine, and are the

design of William H. Hoffman. The cross-sectional view of the boiler

shell in Figure 315 shows the arrangement of the tubes, which, having

clear or unobstructed passages between the vertical rows of tubes,

permits the steam to rise freely and assists the circulation of the

water. The dry pipe (which is also shown in Figure 316) is a perforated

pipe through which the steam passes to the engine cylinder, its object

being to carry off the steam as dry as possible; that is to say, without

its carrying away with the steam any entrained water that may be

held in suspension. Figure 316 is a side elevation with the setting

shown in section, and Figure 317 is an end view of the boiler and

setting at the furnace end. The boiler is supported on each side by

channel iron columns, these being riveted to the boiler shell angle

pieces which rest upon the columns. The heat and products of combustion

pass from the furnace along the bottom of the boiler, and at the end

pass into and through the tubes and thence over the top of the boiler

to the chimney flue. There is shown in the bridge wall an opening, and

its service is to admit air to the gases after they have passed the

bridge wall, and thus complete the combustion of such gases as

may have remained unconsumed in the furnace. The cleansing

door at one end and that lined with asbestos at the other, are to admit

the passage of the tube cleaners. The asbestos at the top of the boiler

shell is to protect it from any undue rise in temperature, steam being a

poorer conductor of heat than water, and it being obvious that if one

side of the boiler is hotter than the other it expands more from the

heat and becomes longer, causing the boiler to bend, which strains and

weakens it. The sides of the setting are composed of a double row of

brick walls with an air space of three inches between them, the object

being to prevent as far as possible the radiation of heat from the

walls. The brick-staves are simply stays to hold the brick work together

and prevent its cracking, as it is apt, in the absence of staying, to

do.

[Illustration: Fig. 318. (Page 299.)]

Figures from 318 to 330 are working drawings of a 100-horse engine,

designed also by William H. Hoffman.

Figure 318 represents a plan and a side view of the bed-plate with the

main bearing and the guide bars in place. The cylinder is bolted at the

stuffing box end to the bed-plate, and is supported at the outer end by

an expansion link pivoted to the bed-plate. The main bearing is provided

with a screw for adjusting the height of the bottom piece of the

bearing, and thus taking up the wear. The guide bars are held to the bed

in the middle as well as at each end.

Figures 319 and 320 represent cross sections of the bed-plate.

[Illustration: Fig. 322--100 H.P. HORIZONTAL STEAM-ENGINE--END VIEW OF

CYLINDER--SCALE 1-1/2" = 1 FOOT. (Page 299.)]

Figure 321 represents a side elevation of the cylinder, and Figure 322

an end view of the same, the expansion support being for the purpose of

permitting the cylinder to expand and contract under variations of

temperature without acting to bend the bed-plate, while at the same time

the cylinder is supported at both ends. The cylinder and cylinder covers

are jacketted with live steam in the steam-spaces shown.

[Illustration: Fig. 330--100 H.P. HORIZONTAL STEAM-ENGINE--CONNECTING

ROD. (Page 303.)]

A view of the steam-chest side of the cylinder is given in Figure 323,

and a horizontal cross section of the cylinder, the steam-chest and the

valves, is shown in Figure 324. The main valves are connected by a right

and left hand screw, to enable their adjustment, as are also the cut-off

valves.

Figures 325 and 326 show the cam wrist plate and the cut-off mechanism.

The cam wrist plate, which is of course vibrated by the eccentric rod,

has an inclined groove, whose walls are protected from wear by steel

shoes. In this groove is a steel roller upon a pin attached to the bell

crank operating the main valve stem. The operation of the groove is to

accelerate the motion imparted from the eccentric to the valve at one

part of the latter's travel, and retard it at another, the accelerated

portion being during the opening of the port for steam admission, and

during its closure for cutting off, which enables the employment of a

smaller steam-port than would otherwise be the case.

The shaft for the cam plate is carried in a bearing at one end, and fits

in a socket at the other, the socket and bearing being upon a base plate

that is bolted to the bed-plate of the engine; a side view of the

construction being shown in Figure 327.

Figure 328 represents the cross-head, whose wrist pin is let into the

cross-head cheeks, so that it may be removed to be turned up true. The

clip is to prevent the piston rod nut from loosening back of itself.

Figure 329 represents a side view; and Figure 329 _a_ a section through

the centre of the eccentric and strap.

[Illustration: Fig. 327--WORKING DRAWING OF 100 H.P.

STEAM-ENGINE.--WRIST PLATE.--3" = 1 FOOT.]

The eccentric is let into the strap and is provided with an eye to

receive a circular nut by means of which the length of the eccentric rod

may be adjusted, a hexagon nut being upon the other or outer end of the

eye.

Figure 330 shows the construction of the connecting rod, the brasses of

which are adjustable to take up the wear and to maintain them to correct

length, notwithstanding the wear, by means of a key on each side of each

pair of brasses, the keys being set up by nuts and secured by check

nuts.
