Comb

“ If you moisten the hair with oil, the comb will still be excited and exert attraction; but, if you moisten it with water, the excitement ceases; a comb passed through wetted hair has no power over the lath.
After its passage through dry or oiled hair, balance the comb itself upon the egg; it is attracted by the lath. You thus prove the attraction to be mutual: the comb attracts the lath, and the lath attracts the comb. Suspend your rubbed glass, rubbed gutta-percha, and rubbed sealing-wax in your wire loop. They are all just as much attracted by the lath as the lath was attracted by them. ”

“ Let the Comb now rest, and let the Paper be removed farther from the Prism, and the several Ranges of Colours will be dilated and expanded into one another more and more, and by mixing their Colours will dilute one another, and at length, when the distance of the Paper from the Comb is about a Foot, or a little more (suppose in the Place 2D 2E) they will so far dilute one another, as to become white. ”

“ Every particle appears to have passed into the composition of definite and elegant machinery. A perfect honey-comb now lies upon the bit of rotten wood, the original support, each cell capped with a filmy lid which seems all too fragile, and which, opening here and there, discloses a powdery, fluffy mass within. ”

“ COMB, an instrument made of horn, ivory, or other materials, and used for separating, cleaning, and dressing flax, wool, hair, &c. Combs for wool are prohibited to be imported into England.
A very useful Comb-pot was invented, a few years since, by John Ashman, an ingenious person employed by Messrs. Daniel and Thomas Dyke, of Sarum. It consists of an almost cylindrical furnace for water, which contains a smaller one, keeping the suds of the second washing of the wool, to be used with the next quantity of wool, the first way. ”

“ A comb is a complicated machine. The principal feature is a large metal ring with rows of fine steel pins (pin circles) , which is made to revolve horizontally within the machine. By various devices the [Pg 40] wool is fed into the teeth of the ring in the form of tufts. The fibers of the tufts by an intricate process are separated into long and short lengths, and a set of rollers draws each out separately and winds it into a continuous strand called “tops.” ”

“ It is impossible to state a relationship between combs and spindles, owing to the great variety of the yarns and fabrics made from worsted. Although no radical improvements have recently been made in the comb, the efficiency has been increased about thirty per cent in the last twenty years. In 1870 the product of a comb was from four hundred to four hundred and fifty pounds a day. The same labor will now produce from seven hundred to eight hundred pounds, yielding a better quality of product. ”

“ It is everywhere about you. The cups that hold our honey and our bread are made of it. The cell in which you were born is of wax; and, besides, it is used to stop the holes in our house. Of course there are different kinds of comb, depending on the use to which it is put. ”

“ Carding and one half of the use of the comb, and the other processes of wool-working which separate the composite, may be classed together as belonging both to the art of wool-working, and also to one of the two great arts which are of universal application—the art of composition and the art of division. ”

“ When you have passed the combs over the panel in this way, first the coarse comb straight, next the medium size with a wave, and lastly, in portions, the finest size comb, your panel is ready for the artistic portion of the work.
Combing does not take long to learn if the worker is cleanly in his habits, but to make a natural and pleasing variety in ‘champing’ or veining takes a great deal of practice; indeed, unless the worker has artistic gifts, he will never be able to master this part of the work perfectly. ”

“ There are several other motions of the comb having the same end in view; and by using the gutta-percha or cork combs, in conjunction with the fine steel, an infinite variety of grain may be produced. Steel combs, with one or more folds of thin rag placed over the ends of the teeth are a style of comb which has nothing to recommend it. A natural variation in the grain may be produced by one comb alone, according to the manner in which it is held. ”

“ Again wool is to be treated like hair. Hold the strand in the middle as before. Comb each end with the fine comb. Notice that the fine comb is removing the short fibers and leaving the long fibers between the fingers. This is the second process of combing, and is called combing.
5. The long fibers are called tops and the short fibers are known [Pg 284] as noils. [23] Combing is the process which separates the long fibers known as tops from the short fibers known as noils.
6. The combing machine in the mill is a very complicated one. ”

“ Almost in every comb irregular and unfinished cells are to be found, especially where the several divisions of a comb come together. The small architects do not begin their comb from a single centre, but begin building from many different points, so as to progress as rapidly as possible, and so that the greatest number may work simultaneously ”

“ Which fine-tooth comb ought not to be used at any other time except for the purpose of examination, as the constant use of a fine-tooth comb would scratch the scalp, and would encourage a quantity of scurf to accumulate. ”

“ Sometimes the weakening is inappreciable—when the comb is essentially single; sometimes it is great, and the result is a comb in which the median element is reduced to one-half; sometimes, finally, the determiner of median comb is so completely weakened by its dilution with "no-median" as not to be able to develop, and we have the cup comb with only a trace of the median element. Nevertheless, such a cup comb is heterozygous and produces both single-combed and Polish-combed germ-cells. ”

“ Moreover, judging from observations only, I have discovered that a comb and brush, if securely chained up, can be used on any number of heads without damaging results.
"Observation cannot be considered complete without its being turned upon one's fellow-creatures. ”

“ The exact and uniform size of their cells is perhaps as great a mystery as anything pertaining to them; yet, we find the second wonder before we are done with the first. In building comb, they have no square or compass as a guide; no master mechanic takes the lead, measuring and marking for the workmen; each individual among them is a finished mechanic! ”

“ This is far more severe labour than any subservient to machinery, and is carried on in rooms rendered close and hot by the number of stoves requisite to heat the combs, and so enable them to render the fibres soft, flexible, and elastic. This is a task at which only robust men are engaged. They use three implements: 1. a pair of combs for each person; 2. a post, to which one of the combs can be fixed; 3. a comb-pot, or small stove for heating the teeth of the combs. Each comb is composed either of two or three rows of pointed tapering steel teeth, b, fig. ”

“ The comb-like instrument is forced into it about 4 cm. from the end of the base and the teeth are held against the first finger by pressure of the thumb. The leaf length is then drawn up by the other hand and is cut into straws depending in width upon the fineness of the comb used. If the leaves are too young they will break in this process. The stripped segments are then usually tied up into bundles as large around as the fist, and hung in some shaded place exposed to the wind. ”

“ A frame of comb should never be turned horizontally, for in that position the comb is apt to break. The proper way is to lower one end of the frame until it is in a perpendicular position, then swing it round half a turn and lower the other end. ”

“ Combs for dressing and cleansing the hair, are made of horn, shell, bone, ivory, and wood; but it is unnecessary to be particular in describing the manner in which every kind of comb is manufactured. We will only add, that the teeth of fine ivory and bone combs are cut with a buzz, or circular saw, which, fastened to a mandrel, is moved in a lathe.
THE BRUSH-MAKER.
1. There are few manufactured articles in more general use than brushes. This has arisen from their [139] great utility, and the low prices at which they can be purchased. ”

“ There are at least four pairs of drawing-off rollers in a comb, and the fibres drawn off by each—be it noted continuously—are united to form a sliver which is passed through a revolving funnel into a can. ”

“ This has the effect of breaking the wavy combing into short and long straight bits, similar to the pores or grain of the real wood. Both the first and second combing may be varied by holding the comb in a slanting direction, and may be fine or coarse, according to the width of the combs used; now take a soft rag folded, and with this partially clear off the grain which runs over the figure, leaving only a sufficient quantity crossing the light or figure, to be just distinguished, exactly as it appears upon the figure in real oak. ”

“ The middle combs are connected by a rustic colonnade of from forty to fifty of these pillars; the upper and lower combs by a smaller number.
The cells are of different sizes, corresponding to that of the three orders of individuals which compose the community; the largest for the grubs of females, the smallest for those of workers. The last always occupy an entire comb, while the cells of the males and females are often intermixed. ”

“ The rubber combs should be coarse and fine—that is, the spaces between the teeth of the fine rubber comb should measure from one-sixteenth to one-eighth of an inch and the coarse one from one-eighth to one-quarter of an inch. Sometimes a rubber comb with the teeth cut graduated looks well introduced among the other work. Where the work is to be shaded or over-grained it is better to cover the teeth of the rubber combs with a thin cotton rag before using, taking a clean place on the rag for every time the comb is used, but on cheap work this may be omitted. ”

“ Passing over one or two intermediate stages after the combs are thus cut and twinned—such as "thinning" on the outer edge by means of grindstones, and "pointing," by means of peculiarly-shaped bevel-saws—we arrive at the next department, where the finishing is given by the hand. Here we meet with artificers who, with a pertinacious reverence for ancient usages, preserve among themselves the appellation of comb-makers par excellence, forgetting that the very boys and girls in their respective departments play as important a part in the aggregate production. ”

“ The old comber would take a short length of sliver, hang it on a nail by tying one end together and then proceed to comb out the short fibres much as one may comb out the dead short hairs from a dog’s coat. ”

“ When he finds a simple geometrical construction, for instance in the honey-comb, he would fain refer it to psychical instinct or design rather than to the operation of physical forces; when he sees in snail, or nautilus, or tiny foraminiferal or radiolarian shell, a close approach to the perfect sphere or spiral, he is prone, of old habit, to believe that it is after all something more than a spiral or a sphere, and that in this “something more” there lies what neither physics nor mathematics can explain. ”

“ Thus, in a mechanical mixture, we have groups of molecules of one substance mingled irregularly with groups of molecules of another substance, so that the atoms which are to combine are not in close proximity one to another, but, on the contrary, are, many of them, separated by wide intervals. In the chemical compound, however, the atoms are regularly distributed throughout the whole mass of the substance, and are, relatively to one another, in the most favourable position for combining. ”

“ The process of combing consists of subjecting the card sliver to the operations of the automatic wool comber, which straightens the fibers and removes all short and tufted pieces of wool. Combing is a guarantee that every fiber of the wool lies perfectly straight, and that all fibers follow one after the other in regular order. ”

“ The object of combing is to effect an orderly arrangement of the wool so that it is ready for spinning. One method, corresponding to carding, is to draw the wool repeatedly between rows of upright spikes set in a wooden frame until every matted particle has been separated and all the fibres are disentangled. ”

“ The conceptions of “element,” “compound” and “mixture” became more precise than they had been hitherto; in an element all the atoms are alike, in a compound all the molecules are alike, in a mixture there are different kinds of molecules. If we accept the hypothesis that each kind of atom has a specific and invariable weight, we can, with the aid of the above theory, make most important inferences concerning the proportions by weight in which substances combine to form compounds. ”

“ But if we analyze any one of these compound words, Finger-hut, for instance, we shall perceive that while each of the so-called elements of combination, Finger and Hut, has a distinct meaning, which enters into the more specific meaning of the compound, yet they are not, in any true sense, elements, or, in other words, that they are not the ultimate elements of the compound words. ”

“ When two bodies, A and B, combine in multiple proportions; for instance, 10 parts of A combine with 7 of B, to form one compound, and with 14 to form another, we are directed by some authors to take the smallest combining proportion of one body as representative of the elementary particle or atom of that body. ”

“ On the other hand, when elements combine to form a compound, the unit of the new body, composed as it is of two or more atoms of different elements linked together, is known as a molecule. (Probably the elements also exist in the molecular state, the atoms of which they are composed being linked together in groups.) Both atoms and molecules are, of course, very minute in size. ”
