In modern days the comb probably reached its most costly and ornamental state at the court of Louis XIV., where hair-dressing was an art more appreciated and often better paid than the higher efforts of genius. Combs of ivory and of tortoise-shell, richly inlaid with gold and pearl, formed an essential adjunct of the toilet of the court beauties. In Great Britain the fabrication of horn into combs was a very ancient process, chiefly in Yorkshire and the midland counties. But towards the end of the last century the increased demand for combs caused makers to establish themselves all over the country; and in Scotland there were one or two houses of some eminence in the trade at the period—some twenty-five years back—at which we have now arrived. It was, however, one of those trades that, as its artificers were concerned, would not stand investigation. Making combs on nearly the same principles as those pursued by their forefathers—that is, by simply cutting out the interspace between the teeth, with various sorts and sizes of saws—its followers, barely entitled to the name of skilled workmen, were dissipated, unsettled, and irregular in their habits.
We come now to treat of the grand era in the comb trade—of the time when it was destined, like the great staple manufactures of our country, to undergo a revolution. The introduction of machinery and steam-power, with the division of labor, is suggestive of an important stride in the progress of the trade. About the year 1828 Mr. Lynn invented a machine of a singularly ingenious design, having for its principal object that of cutting two combs out of one plate of horn or shell; and two years afterwards Stewart, Rowell & Co. commenced the manufacture in Aberdeen. To the first of these circumstances the trade was indebted for the successful idea of a machine, which affected at the same time a saving of half the material, and an increase of produce almost inconceivable. To the latter it is still more indebted for the first application of steam-power to the machinery; and, what we think of infinitely greater importance, the introduction of those true principles in the philosophy of production contended for by Adam Smith—a philosophy which, in its legitimate application, has the invariable effect of elevating alike the character of the produce and the producers.
We shall most appropriately represent the combined effect of these improvements on the trade by taking the reader along with us in a cursory view of the principal departments of the Aberdeen Combworks. Provided with an intelligent cicerone in the person of one of the clerks of the office, we began our investigations, and as an essential preliminary, were first shown specimens of the various kinds of raw material. In the order of its intrinsic value, this consists of tortoise-shells, horns, and hoofs. Ivory, in our day, is reserved almost exclusively for the manufacture of small-tooth combs, which form a branch of the ivory trade distinct from the one before us. Of the first of these materials, tortoise-shell, that best adapted to manufacturing purposes is the shell, or scales of a horny contexture which inclose the sea-tortoise, Testudo imbricata. It is found in all warm latitudes; but the best species are indigenous to Hindostan, the Indian Archipelago, and the shores of the Red Sea. The price we are apt to think excessive. At present it is thirty-five shillings per pound, and ten years ago it was nearly double that price. It forms however a valuable article of importation. There are two chief divisions in horn, buffalo and ox horns, both of which are imported from various parts of the globe. Buffalo horn is for the most part used in the manufacture of knife-handles, and such articles, in the cutlery trade. In comb-making it is chiefly used for dressing-combs, and, generally speaking, all combs of a deep black color are formed of this material. The best buffalo-horns are obtained from the East Indies, and the finest are those of the Indian buffalo from Siam. We were shown a beautiful specimen of Siamese horns, which, on account of their extraordinary dimensions, had been preserved and polished. One of them measured five feet from tip to base, eighteen and a half inches in circumference at the widest part, and weighed fourteen pounds. Some conception may be formed of the size of an animal which can support such a weight on the frontal-bone, if we recollect that an English ox-horn weighs only a single pound.
Ox-horns, the staple of comb-makers, are imported with hides from South America, the Cape of Good Hope, and New South Wales. The imports, however, are chiefly from the enormous herds of South American black-cattle, which have multiplied to such an extent in the Brazilian territories, that they are now slaughtered for the sake of their hides and horns, and their carcasses left to be devoured by the innumerable carnivorous animals which infest the jungles. The ox-horns entered for consumption in Great Britain in 1850 numbered 1,250,000, and the average price is about fifty pounds per ton.
Hoofs are from the German and home markets, and are worth about twelve pounds per ton. They are used generally in the cheapest description of combs, but although the least valuable material, are subject to the most costly and ingenious processes of manufacture.
At the time of our visit the quantity of horns and hoofs in stock amounted to upwards of one hundred tons of each. Enormous piles of different varieties—from the delicate curvature of the small Highland ox to the equally beautiful but enormous cornu of the ferocious buffalo of the Cape; from the Smithfield horns to those of the gigantic buffalo of Thibet and Siam—all lay piled in inextricable confusion.
After a glance at the steam-engine, fifty horse-power, and the largest of the horizontal kind in Scotland, we proceeded to see the first stage of the manufacture, where horns are cut into assorted sizes by a circular saw. A horn is twice cut transversely, and afterwards, if a large one, longitudinally. The tips or extremities here cut off are sent to Sheffield, where they are converted into table-knife and umbrella handles; and for this purpose sixteen thousand horns can be cut up in a week. Instead of being divided in this manner, the hoofs are, after being boiled a certain time, to render the fibre soft, cut into two pieces; or rather the sole is stamped out by vertical punching-machines of the same irregular conformation.
The horns and hoofs thus cut are then brought in pieces into the pressing department. The first thing that strikes the visitor on entering is the peculiar and easily distinguishable odor of burnt horn, which indeed is predominant throughout the works. This arises from the high temperature necessary to the fabrication of horn, which to a greater or less extent effects decomposition of the material, and is invariably accompanied with the disengagement of the peculiar gases which create the odor. Along the floor of this department are thirty-six furnaces of a peculiar construction, and at each of these a man and boy were busily engaged in shaping the cut horns into flat plates, by heating the pieces, and then cutting them to the required shape with knives. They were then inserted between screw-blocks, and pressed flat. If, however, the plates are required for stained combs, as the greater part of them are, a different mode of pressing is pursued. Into a rectangular cast-iron trough about two and a half feet long by twelve inches wide and deep, a number of iron hot-plates are put; they are then oiled on their surface, and the plates of horn inserted between them; a wedge is next driven into the press by the percussion-force of a weight falling eight feet, producing a force of about one hundred and twenty tons. This pressure on the horn in the iron plates has the effect of breaking the fibre to a certain degree, and forcing it to expand in a lateral direction. Whatever may have been the original color of the horn, it is now of a uniform dark green color, and perfectly soft. This treatment renders the tissues more pervious to the action of acids, and will be better understood when we arrive at the operation of staining.
But there are other means of pressure. Around the apartment were arranged one hundred and twenty iron screw-presses—levers of the second order, and differing only from a common vice in pressing under the screw after the manner of nut-crackers. They are fitted with steel dies, with a variety of engraved designs, and in these braid-combs, the outside coverings of pocket-combs and side-combs are pressed. We were shown a new impression on pocket-combs of the Crystal Palace. A man exerting his strength on one of these presses can produce a force of upwards of fifty tons. But however great, the pressure is still insufficient. The enormous demand for the cheap side-combs of hoof led to the application of hydraulic pressure. The two portions of the hoof, after being boiled a second time in a number of little troughs, with a steam-jet in each of them to preserve the necessary temperature, the excrescences still adhering are pared off. They are then transferred to an adjoining room, where sixteen hydraulic presses, are in operation; and here are subjected to a pressure of three hundred tons, with a degree of speed and precision that is astonishing. They come out of the press in the form of small, semi-transparent, rectangular plates, having on each side the rounded projection or beading observable on most side-combs. To illustrate the resistless force of this pressure, we were informed that the very steel dies which give shape to the hoof are soon crushed and worn out; and it was not without some nice calculation and experiment that the application of hydraulic pressure to the purpose was successfully attained. After having received the necessary formation by the various modes of pressing, the plates are laid aside to dry in a room where a high temperature is preserved by means of steam-pipes, and where they are also assorted into different sizes, and the edges squared with circular saws. The number of such plates, of shell, horn, and hoof, in stock at the time of our visit, was somewhere about four millions and a half.
From this they are distributed to the different processes in order—the first of which is cutting the teeth. Certain classes of horn-plates, however, are subjected to a farther process of planing on the surface preliminary to this operation; but in all plates which have been hot-pressed, and are intended to be stained, this is unnecessary, and therefore they are taken when perfectly dry to the cutting department. On entering this department the visitor is sometimes bewildered. The incessant and peculiar clatter of the machinery, the heat of the place, and apparent confusion, produce together a curious effect. A little observation, however, shows that we have arrived at the basis of all the modern improvements in comb-making. On benches around the apartment, in close proximity to each other, were twenty-four "twinning-machines"—the invention, with its subsequent improvements, to which we have referred. Each of these is worked by a man, with an attendant who keeps up a supply of hot plates from the fires arranged for that purpose in the centre of the room. It is impossible without diagrams to explain the principles and construction of this apparatus; but there can be no mistaking its effect. A plate of horn, after being heated, is placed on a small carriage within the cast-iron frame of the machine, which travels by means of a particular arrangement of gearing on parallel slides. Immediately over this are two angular-shaped chisel-like cutters, which, on the application of motive power, descend on the horn with an alternating motion, and an inconceivable degree of rapidity and force. Before we could well see, far less understand, the rationale of the process, we were shown the horn cut in two pieces—one half literally taken out of the other, and each presenting the well-defined outline of a comb. In this cutting department resides the perfection of that beautiful mechanism that revolutionized the trade and reduced it to mathematical precision. To appreciate this we have only to look at the increase it has effected in the production. A comb-maker of the old school could not perhaps, with all his skill, cut more than eighty or a hundred combs per day; while with this machinery a man and boy will cut upwards of two thousand of the same kind, and with a consumption of only half the material. The finer dressing-combs, and all small-tooth combs, are still cut by circular saws in the next department. Here, however, a moderately curious visitor will not linger. A dense atmosphere of horn dust fills the large apartment, and gives to every thing within its influence the white appearance that distinguishes a flour-mill, to which indeed at first sight it bears a striking resemblance. From the notes we took, we learn that here there are wheels on the fine self-acting machinery, in connection with the cutting and pointing of combs, that revolve 5000 times in a minute, and saws so delicately fine as to cut forty teeth within the space of an inch.
