CHAPTER XXI.

WOOD-WORKING.

In surveying the wonderful road along which have travelled the toiling

inventors, until the splendid fields of the present century have been

reached, the mind indulges in contrasts and reverts to the far gone

period of man’s deprivations, when man, the animal, was fighting for

food and shelter.

“Poor naked wretches, wheresoe’er you are,

That bide the pelting of this pitiless storm,

How shall your houseless heads and unfed sides,

Your loop’d and window’d raggedness, defend you

From seasons such as these?”

--_King Lear III, IV._

When the implements of labour and the weapons of war were chiefly made

of stone, or bronze, or iron, such periods became the “age” of stone, or

bronze, or iron; and we sometimes hear of the ages of steam, steel and

electricity. But the age of wood has always existed, wherever forests

abounded. It was, doubtless, the earliest “age” in the industries of

man, but is not likely to be the latest, as the class of inventions we

are about to consider, although giving complete dominion to man over the

forests, are hastening their destruction.

As in every other class of inventions, there had been inventions in the

class of wood-working through the ages preceding this century, in tools,

implements and machines; but not until near the close of the eighteenth

century had there been much of a break in the universal toil by hand.

The implements produced were, for the most part, the result of the slow

growth of experience and mechanical skill, rather than the product of

inventive genius.

True, the turning-lathe, the axe, the hammer, the chisel, the saw, the

auger, the plane, the screw, and cutting and other wood-shaping

instruments in simple forms existed in abundance. The Egyptians used

their saws of bronze. The Greeks deified their supposed inventor of the

saw, Talus, or Perdix, and they claimed Theodore of Lamos as the

inventor of the turning-lathe; although the main idea of pivoting an

object between two supports, so that it could be turned while the hands

were free to apply a tool to its shaping, was old in the potter’s wheel

of the Egyptians, which was turned while the vessel resting upon it was

shaped and ornamented by the hand and tools. It appears also to have

been known by the Hindoos and the Africans.

Pliny refers to the curled chips raised by the plane, and Ansonius

refers to mills driven by the waters of the Moselle for sawing marble

into slabs. Early records mention saw-mills run by water-power in the

thirteenth century in France, Germany and Norway; and Sweden had them in

the next century. Holland had them one hundred years at least before

they were introduced into England.

Fearful of the entire destruction of the forests by the wood used in the

manufacture of iron, and incited by the opposition and jealousy of hand

sawyers, England passed some rigid laws on the subject in the sixteenth

and seventeenth centuries, which, although preserving the forests, gave

for a long time the almost exclusive manufacture of iron and lumber to

Germany and Holland. Even as late as 1768, a saw-mill, built at

Limehouse, under the encouragement of the Society of Arts, by James

Stansfield, was destroyed by a mob. Saw-mills designed to be run by

water-power had been introduced into the American colonies by the Dutch

more than a century before they made their appearance in England.

William Penn found that they had long been at work on the Delaware when

he reached its shores in 1682.

It was nothing indigenous to the climate or race that rendered the

Americans inventors. The early colonists, drawn from the most civilised

countries of Europe, carried to the new world knowledge of the latest

and best appliances known to their respective countries in the various

arts. With three thousand miles of water between them and the source of

such appliances, and between them and the source of arbitrary power and

laws to hamper efforts and enterprise, with stern necessity on every

hand prompting them to avail themselves of every means to meet their

daily wants, all known inventions were put to use, and brains were

constantly exercised in devising new means to aid, or take the place of,

manual labour, which was scarce. Surrounded, too, by vast forests, from

which their houses, their churches and their schools must be

constructed, these pioneers naturally turned their thoughts toward

wood-working machinery. The attention to this art necessarily created

interest in and developed other arts. Thus constant devotion to pursuits

strenuously demanding labour-saving devices evolved a race of keen

inventors and mechanics. So that when Watt had developed his wonderful

application of steam to industrial purposes, America was ready to

substitute steam for water-power in the running of saw-mills.

Steam saw-mills commenced to buzz with the opening of the century.

As to the relation of that humble machine, the saw-mill, to the progress

of civilisation, it was once said: “The axe produces the log hut, but

not until the saw-mill is introduced do framed dwellings and villages

arise; it is civilisation’s pioneer machine; the precursor of the

carpenter, wheelwright and turner, the painter, the joiner, and legions

of other professions. Progress is unknown where it is not. Its

comparative absence in the Southern American continent was not the least

cause of the trifling advancement made there during three centuries and

a half. Surrounded by forests of the most valuable and variegated

timber, with water-power in mountain streams, equally neglected, the

masses of the people lived in shanties and mud hovels, not more

commodious than those of the aborigines, nor more durable than the

annual structures of birds. Wherever man has not fixed and comfortable

homes, he is, as regards civilisation, stationary; improvement under

such circumstances has never taken place, nor can it.”

Miller, in England, in 1777, had described in his patent a circular saw,

and Hatton, in 1776, had vaguely described a planing machine; but the

inception of the marvellous growth in wood-working machinery in the

nineteenth century occurred in England during the last decade of the

eighteenth. It was due to the splendid efforts of General Samuel

Bentham, and of Bramah and Branch, both as to metal-working and

wood-working machinery.

General Bentham, a brother of the celebrated jurist, Jeremy Bentham, had

his attention drawn to the slow, laborious, and crude methods of working

in wood, while making a tour of Europe, and especially in Russia, and

engaged in inspecting the art of ship-building in those countries, in

behalf of the British Admiralty. On his return, 1791-1792, he converted

his home into a shop for making wood-working machines. These included

“Planing, moulding, rabbeting, grooving, mortising, and sawing, both in

coarse and fine work, in curved, winding, and transverse directions, and

shaping wood in complicated forms.”

Of the amount of bills presented to and paid for by the Admiralty for

these machines, General Bentham received about £20,000.

These machines were developed and in use just as the new century

approached. Thus, with the exception of the saw-mill, it may be again

said that prior to this century the means mankind had to aid them in

their work in metals and in wood were confined to hand tools, and these

were for the most part of a simple and crude description.

The ground-work now being laid, the century advanced into a region of

invention in tools and machinery for wood-working of every description,

far beyond the wildest dreams of all former carpenters and joiners. Not

only were the machines themselves invented, but they gave rise in turn

to a host of inventions in metal-working for making them.

In the same line of inventions there appeared in the first decade of the

century one of the most ingenious of men, and a most fitting type of

that great class of Yankee inventors who have carved their way to renown

with all implements, from the jack-knife to the electrically-driven

universal shaping machine.

Thomas Blanchard, born in Massachusetts in 1788, while a boy, was

accustomed to astonish his companions by the miniature wind-wheels and

water-wheels that he whittled out with his knife. While attending the

parties of young people who gathered on winter evenings at different

homes in the country to pare apples, the idea of a paring machine

occurred to him, and when only thirteen years of age, he invented and

made the first apple-paring machine, with which more apples could be

pared in a given time than any twelve of his girl acquaintances could

pare with a knife.

At eighteen, while working in a shop, driving the heads down on tacks,

on an anvil, with a hammer, he invented the first tack-forming machine,

which, when perfected by him, made five hundred tacks a minute, and

which has never since been improved in principle. He improved the steam

engine, and invented one of the first envelope machines. He made the

first metal lathe for cutting out the butts of gun-barrels. But his

greatest triumphs were in wood-working machinery.

Challenged to make a machine that would make a gun stock, always before

that time regarded an impossible task, its every part being so irregular

in form, he secluded himself in his workshop for six months, and after

constant labour and experiments he at the end of that time had produced

a machine that more than astonished the entire world, and which worked a

revolution in the making of all irregular forms from wood. This was in

1819. This machine would not only make a perfect gun-stock, but shoe

lasts, and ships’ tackle-blocks, axe-handles, and a multitude of

irregular-shaped blocks which before had always required the most expert

hand operatives to produce. This machine became the subject of

parliamentary inquiry on the part of England, and so great were the

doubts concerning it, that successive commissions were appointed to

examine and report upon it. Finally the English government ordered eight

or ten of such machines for the making of gun-stocks for its army, and

paid Blanchard about $40,000 for them. He was once jestingly asked at

the navy department at Washington if he could turn a seventy-four? He at

once replied, “Yes, if you will furnish me the block.” Of course

infringers appeared, but he maintained his rights and title as first and

original inventor after the most searching trials in court.

The generic idea of Blanchard’s lathe for turning irregular forms

consists in the use of a pattern of the device which is to be shaped

from the rough material, placing such pattern in a lathe, alongside of

the rough block, and having a guide wheel which has an arm having

cutters, and which guide follows all the lines of the pattern, and which

cutters, extending to the rough material, chip it away to the depth and

in the direction imparted by the pattern lines to the guide, thus

producing from the rough block a perfect representation of the pattern.

In the midst of his studies in the construction of his inventions

Blanchard’s attention was drawn to the operations of a boring worm upon

an old oak log. Closely examining and watching the same by the aid of a

microscope, he gained valuable ideas from the work of his humble

teacher, which he incorporated into his new cutting and boring machines.

His series of machines in gun-making were designed to make and shape

automatically every part of the gun, whether of wood or metal. His

machines, and subsequent improvements by others, for boring, mortising

and turning, display wonderful ingenuity. A modern mortising machine,

for instance, is adapted to quickly and accurately cut a square or

oblong hole to any desired depth, width, and length by cutting blades;

to automatically reciprocate the cutters both vertically and

horizontally in order to cut the mortise, both as to length and depth,

at one time, and to automatically withdraw the cutters when they have

finished cutting the mortise. They are provided with simple means for

setting and feeding the cutters to do this work, and while giving the

cutters a positive action, ample clearance is provided for the removal

of the chips as fast as they are cut.

From what such inventions will produce in the way of complicated and

ornamental workmanship we may conclude that it is a law of invention

that whatever can be made by hand may be made by a machine, and made

better.

_Carving Machines_ made their appearance early in the century. In 1800 a

Mr. Watt of London produced one, on which he carved medallions and

figures in ivory and ebony. Also subsequently, John Hawkins of the same

city, and a Mr. Cheverton, invented machines for the same purpose.

Another Englishman, Braithwaite, in 1840, invented a most attractive

carving process in which, instead of cutting tools, he employed

_burning_ as his agent. Heated casts of previously carved models were

pressed into or on to wet wood, and the charcoal surfaces then brushed

off with hard brushes.

After Blanchard’s turning-lathes and boring apparatus, appeared machines

in which a series of cutters were employed, guided by a tracing lever

attached to a carved model, and actuating the cutter to reproduce on

material placed upon an adjusting table a copy of the model.

Machines have been invented which consist of hard iron or steel rollers

on the surface of which are cut beautiful patterns, and between which

wood previously softened by steam is passed, and designs thus impressed

thereon. A similar process of embossing, was devised in Paris and called

Xyloplasty, by which steam-softened wood is compressed in carved moulds,

which give it bas-relief impressions.

But in the carving of wood by hand, a beautiful art, which has been

revived within the past generation, there are touches of sentiment,

taste and human toil, which, like the touches of the painter and the

master of music, appeal to cultivated minds in a higher than mechanical

sense. The mills of the modern gods, the inventors, grind with exceeding

and exact fineness, but the work of a human hand upon a manufactured

article still appeals to human sympathy.

The bending of wood when heated by fire or steam had been known and

practised to a limited extent, but Blanchard invented a _clamping

machine_, to which improvements have been added, and by which ship

timbers, furniture, ploughs, piano frames, carriage bows, stair and

house banisters and balusters, wheel rims, staves, etc., etc., are bent

to the desired forms, and without breaking. Bending to a certain extent

does not weaken wood, but stretching the same has been found to impair

and destroy its strength.

The principal problems which the inventors of the century have solved in

the class of wood-working have been the adaptation to rapid-working

machinery of the saw and other blades, to sever; the plane to smooth,

the auger, the bit and the gimlet to bore, the hammer to drive, and a

combination of all or a part of these to shape and finish the completed

article.

It was a great step from the reciprocating hand saw, worked painfully by

one or two men, to the band saw, invented by a London mechanic, William

Newbury, in 1808. This was an endless steel belt serrated on one edge,

mounted on pulleys, and driven continuously by the power of steam

through the hardest and the heaviest work. Pliable, to conform to the

faces of the wheels over which it is carried, it will bend with all the

sinuosities of long timber, no time is lost in its operation, and no

labour of human hands is necessary to guide it or the object on which it

works.

At the Vienna Exposition in 1873, the first mammoth saw of this

description was exhibited. The saw itself was made by the celebrated

firm of Perin & Co., of Paris, upon machinery the drawings of which were

made by Mr. Van Pelt of New York, and constructed by Richards, Loudon

and Kelly of Philadelphia. The saw was fifty-five feet long, and sawed

planks from a pine log three feet thick, at the rate of sixty

superficial feet per minute. The difficulty of securing a perfectly

reliable weld in the endless steel band was overcome by M. Perin, who

received at the Paris Exhibition in 1867 the Grand Cross of the Legion

of Honour. Now gangs of such saws may be found in America and elsewhere,

and circular saws have also been added. Saws that both cut, form, and

_plane_ the boards at the same time are now known.

_Boring tools_, both for hand and machinery, demanded improvement.

Formerly augers and similar boring tools had merely a curved sharpened

end and a concavity to hold the chips, and the whole tool had to be

withdrawn to empty the chips. It was known as a _pod_ auger. In 1809,

L’Hommedieu, a Frenchman, invented an auger with two pods and cutting

lips, a central screw and a twisted shank. About the same time Lilley of

Connecticut made a twisted auger, and these screw-form, twisted, cutting

tools of various kinds, with their cutting lips, and by which the

shavings or chips were withdrawn continuously from the hole as the

cutting proceeded, became so improved in the United States that they

were known as the American augers and bits. The planing machines of

General Bentham were improved by Bramah, and he and Maudsley also

greatly improved other wood-working machines and tools in

England--1802-1810.

We have before, in the chapter on metal-working, shown the importance of

the _slide-rest_, _planer_ and _lathe_, _when combined_, and which also

are extensively adapted to wood-working. In Bramah’s machine, a vertical

spindle carried at its lower extremity a horizontal wheel having

twenty-eight cutter blades, followed by a plane also attached to a

wheel. A board was by these means perfectly trimmed and smoothed from

end to end, as it was carried against the cutters by suitable moving

means. William Woodworth of New York, in 1828, patented a celebrated

planing machine which became so popular and its use was regarded so

necessary in the wood-working trades, that the patent was looked upon as

an odious monopoly. It consisted of a combination of rollers armed with

cutters, attached to a horizontal shaft revolving at a great speed, and

of means for feeding the boards to the cutters. With Bentham’s,

Bramah’s, Blanchard’s, and Woodworth’s ideas for a basis, those

innumerable improvements have been made in machinery, by which wood is

converted with almost lightning rapidity into all the forms in which we

see it, whether ornamental or useful, in modern homes and other

structures.

Some machines are known as “Universal Wood Workers.” In these a single

machine is provided with various tools, and adapted to perform a great

variety of work by shifting the position of the material and the tools.

The following operations can be performed on such a machine:--Planing,

bevelling, tapering, tenoning, tongueing and grooving (grooves straight,

circular or angular), making of joints, twisting and a number of other

operations.

The later invention by Stow of Philadelphia of a _flexible_ shaft, made

up of a series of coils of steel wire, given a leather covering, and to

which can be attached augers, bits, or metal drills, the tool applied to

its work from any direction, and its direction varied while at work, has

excited great attention.

_Shingles_ are as old in the art as the framework of buildings. Rome was

roofed with shingles for centuries, made of oak or pine.

Tiles, plain and fancy, and slates, have to a certain extent superseded

wood shingling, but the wood will always be used where it can be found

in plenty, as machines will now turn them out complete faster than they

can be hauled away. A shingle is a thin piece of wood, thicker at one

end than at the other, having parallel sides, about three times as long

as it is wide, having generally smooth surfaces and edges. All these

features are now given to the shingle by modern machines.

A great log is rolled into a mill at one end and soon comes out at the

other in bundles of shingles; the logs sawed into blocks, the blocks

split or sawed again into shingle sizes, tapered, planed in the

direction of the grain of the wood, the complete shingles collected and

bound in bundles, each operation by a special machine, or by a series of

mechanisms.

_Veneering_, that art of covering cheap or ordinary wood with a thin

covering of more ornamental and valuable wood, known from the days of

the Egyptians, has been vastly extended by modern machinery. The

practice, however, so emphatically denounced centuries ago by Pliny, as

“the monstrous invention of paint and dyes applied to the woods or

veneers, to imitate other woods,” has yet its practitioners and

admirers.

T. M. Brunel, in 1805-1808, devised a set of circular saws run by a

steam engine, which cut sheets of rosewood and mahogany, one-fourteenth

of an inch thick, with great speed and accuracy. Since that day the

veneer planing machine, for delicately smoothing the sheets, the

straightening machine, for straightening scrolls that have been cut from

logs, the polishing machines for giving the sheets their bright and

glossy appearance, the pressing machine for applying them to the

surfaces to which they are to be attached, the hammering machine for

forcing out superfluous glue from between a veneer and the piece to

which it is applied; all of these and numerous modifications of the same

have been invented, and resulted in placing in the homes everywhere many

beautiful ornamental articles of furniture, which before the very rich

only could afford to have.

Special forms of machinery for making various articles of wood are about

as numerous as the articles themselves.

We appear before the house and know before entering that its doors and

sills, clapboards and window frames, its sashes and blinds, its

cornices, its embrasures and pillars, and shingles, each or all have had

a special machine invented for its manufacture. We enter the house and

find it is so with objects within--the flooring may be adorned with the

beautiful art of marquetry and parquetry, wood mosaic work, the

wainscoting and the frescoes and ceilings, the stairs and staircases,

its carved and ornamental supporting frames and balusters, the charming

mantel frames around the hospitable fireplaces, and every article of

furniture we see in which wood is a part. So, too, it is with every

useful wooden implement and article within and without the house,--the

trays, the buckets, the barrels, the tubs, the clothes-pins, the

broom-handles, the mops, the ironing and bread boards; and outside the

house, the fences, railings and posts--many of these objects entirely

unknown to the poor of former generations, uncommon with the rich, and

the machinery for making them unknown to all.

It was a noble array of woodwork and machinery with which the nations

surprised and greeted the world, at each of its notable international

Expositions during the century. Each occasion surpassed its predecessor

in the beauty of construction of the machines displayed and efficiency

of their work. The names of the members of this array were hard and

uncouth, such as the axe, the adze, and the bit, the auger, bark-cutting

and grinding machines, blind-slat boring, and tenoning, dovetail,

mortising, matching and planing, wood splitting, turning, wheeling and

planing, wood-bending, rim-boring dowelling, felly-jointing, etc., etc.

These names and the clamour of the machines were painful to the ear, but

to the thoughtful, they were converted into sweeter music, when

reflection brought to mind the hard toil of human hands they had saved,

the before unknown comforts and blessings of civilisation they had

brought and were bringing to the human race, and the enduring forms of

beauty they had produced.

To the invention of wood-working machinery we are also indebted for the

awakening of interest in the qualities of wood for a vast number of

artistic purposes. It was a revelation, at the great Philadelphia

Exposition of 1876, to behold the specimens of different woods from all

the forests of the earth, selected and assembled to display their

wonderful grain and other qualities, and showing how well nature was

storing up for us in its silent shades those growths which were waiting

the genius of invention to convert into forms of use and beauty for

every home.
