In the above plans the Hebrew Cases nearly resemble those of the English now in use. The alphabets have been classified and arranged so as to facilitate the composing of it; that is, the three different dotted alphabets in the upper case are quite distinct from each other, being separated by a thicker partition, to lead the eye of the compositor to it with greater certainty. The alphabet, with the dot over the letter, appears first in order, or left hand side of the case; the second alphabet, with the dot in the middle of the letter, under that of the first; and the third alphabet, with the dot over and in the middle of the letter, in the small capital, or right hand side of the case; and underneath, the points and accents required in composing Hebrew with points.

The lower case letters are also arranged as near to the English plan as is possible: the א‎ (a) in the a box; the ב‎ (b) in the b box, &c. so that the compositor can go from a pair of English cases to the Hebrew ones with very little perplexity, and a great saving of time, instead of looking over a wide surface of three cases, as is now the case, without any classification or arrangement whatever.

In composing Hebrew without points the lower case only is required, as the final letters and broad letters are brought into it, and quite under the hand of the compositor, which is desirable.

HERALDRY.

The colours of the escutcheon, or of its ordinaries and charges, are:—

The two first being ordinarily represented by gold and silver, are called metals, and named by heralds after the French.

The two last are rarely seen in English coats of arms. The heraldic colours are usually estimated as five,—red, blue, black, green, purple.

High Bearer. See Bearer.

HIND POSTS AND RAILS.

Two upright posts mortised and tenoned into the feet at the back of the wooden press; two rails connect these posts behind; and two rails on the off side and two on the near side connect them with the cheeks, by mortises and tenons; on the top rails a thin deal covering is laid loose, that it may be lifted off, to allow access to the long ribs, and to hang the platen when necessary; it prevents dirt and other matter from falling on the ribs, and serves for a temporary shelf. The ink block is attached to the near rails.

Hither Cheek. Same as Near Cheek, which see.

Holdfasts, for Stereotype Risers. See Risers.

HOLDS OUT, or Holds Not Out.

These terms are applicable to the quires of white paper, to wrought-off heaps, to gathered books, and to sorts of letter, &c. If quires of white paper have twenty-five sheets apiece in them, they say, the paper holds out five and twenties. Of wrought-off heaps, the heap that comes off first in gathering is said not to hold out. Of gathered books, if the intended number of perfect books are gathered, they say the impression holds out: but if the intended number of perfect books cannot be gathered off the heaps, they say the impression holds not out. And so for sorts of letter, either when it is in the founding house, or in the printing house.—M. There is no paper at the present day with twenty-five sheets in a quire, except that used for newspapers, on account of the stamps.

HOLE.

By a Hole, in printers dialect, is meant and understood a place where private printing is used, viz. the printing of unlicensed books, or printing of other men’s copies. Many printers for lucre of gain have gone into Holes, and then their chief care is to get a Hole private, and workmen trusty and cunning to conceal the Hole, and themselves.—M.

Holy-days. See Ancient Customs.

HOME.

This is a term used at Press, and means that the bar of the press is pulled over till it touches the near cheek; it is then said the bar is home, or it is cheeked. See Cheek the Bar.

HOOK-IN.

In poetry it occasionally happens that a line will not come into the measure, in which case, when it is not allowed to turn a line, if it be possible to avoid it, a syllable, or a word, is taken to the end of the preceding line, or, if that be full, to the end of the following one, and enclosed in a bracket; this is termed Hooking-in.

Hooks of Tympan. See Tympan Hooks.

HORSE.

Form or bench pressmen set the heaps of paper on. See also Ancient Customs.—M. In Moxon’s time it appears the pressmen used what was then called a Horse, only, for the paper when working, which we now call a Bank; we have in addition what is termed a horse, set upon the bank; this horse is made sloping down to the fore edge, and the white paper is placed on it; the pressman is thus enabled to draw the sheets down with the nail of his thumb, or a piece of wood, bone, or ivory, with more facility than if it were laid horizontal, and it is more convenient to remove to the tympan, as the horse is raised near to it, and inclines in the same direction.

HORSE FLESH.

If any journeyman set down in his bill on Saturday night more work than he has done, that surplusage is called Horse-flesh; and he abates it in his next bill.—M. This surplusage of charge, as Moxon terms it, is now called Horse, and it is not always deducted in the next bill.

HORSE RACES.

By the Act of the 13th of George 2. cap. 19.

So much of the act of 13 Geo. 2. c. 19. “as relates to the Subject of Horse Racing,” was repealed by 3 Vict. c. 5. s. 1.

HOSE.

Two upright bars of iron that connected the garter and the hose hooks, and went through the till. There were screws at each end, by which they could tighten the platen cords, if they became slack.—M.

The hose in wooden presses is now quite different: it is a wooden case for the spindle to work in, made hollow in the inside to fit it, and to which it is connected by the garter; it is square on the outside, and passes through an opening in the till, which it should fit accurately; and is tied to the platen by means of four iron hooks, one at each bottom corner. Its uses are, to guide the platen down to the form in a horizontal position, by its passing through the till; and also to lift the platen from off the form, which it does by the return of the press bar, and its connexion with the spindle by means of the garter.

HOSE HOOKS.

Four iron hooks at the bottom corners of the hose, to which the platen is tied. They are projections from an iron belt that embraces the bottom of the hose, and stand facing the platen hooks.

HOURS.

Pressmen reckon their works by hours, accounting every token to an hours work: and though it be the same effectually with tokens, yet they make their prices of different work by the hour; and it passes current for a token. If two men work at the press, ten quires is an hour; if one man, five quires is an hour.—M. The quires of paper at this time always contain twenty-four sheets, at least the inside quires do, which alone are used for bookwork; and a token is ten quires eighteen sheets, which is still called an Hour, whatever the price may be: thus, if two men at a press print twelve tokens of paper in a day, they say, they have done twelve hours; and if it be fine work, at which, through the care bestowed on it, they can only print three tokens, or four tokens, they say, they do three hours, or four hours, in a day; although it takes the same time in performing that the twelve tokens did.

HYDRAULIC PRESS.

This press was invented and introduced to the public by Mr. Joseph Bramah, of Piccadilly, Engineer. Mr. W. Nicholson, in his Journal of Natural Philosophy, Chemistry, and the Arts, vol. 1. April, 1797, gave an account of it, with engravings, from which the following observations are extracted, which will give a brief description of this powerful machine, that is superseding the common book press with a screw in all extensive establishments.

“Its action is as follows: when the lever or pump handle is raised, it brings up the piston, which would leave a vacuum beneath if the pressure of the atmosphere did not force the water in through a side valve. The lever is then to be pressed down, which causes the side valve to shut, and forces the water through a valve at the bottom, whence it passes through a pipe into the cavity of the great cylinder, and raises the piston or pressing rammer. A repetition of the same process forces more water in, and the pressure may in this manner be carried to a great extent.

“There is no difficulty in computing the force of this instrument. If the diameter of the pump barrel be one quarter of an inch, and that of the cylinder one inch, that is to say, four quarters of an inch; one pound lodged upon the piston rod of the pump will be in equilibrio with sixteen pounds lodged upon the table of the press; the weights of the parts of the engine attached to, and moving with each piston, being respectively included. And if the length of the pump lever be fifteen inches, and the distance between the centres of motion and of action be two inches, one pound at the end of the lever will gain an advantage of 7½ times when compared with that at the piston rod. Instead, therefore, of sixteen pounds upon the table being equal in effect to counterpoise this last action, there will be required upwards of 120 pounds. But a man in this action of pumping by a downward pressure, can without difficulty apply his whole weight, and with great ease one third or one fourth of his weight, suppose 50 pounds. In this case the pressure will be equivalent to fifty times 120 pounds, or 6000 pounds, that is to say, nearly three tons.

“To compare this engine with a screw, in theory, we must enquire what fineness of thread and length of lever would afford a purchase of 120 to one. Let us suppose the thread of a screw, substituted in the place of the cylinder, to be one tenth of an inch thick; the distance from the top of one thread to the top of the next will in this case be one fifth of an inch. This is the space through which the weight must rise in one revolution. The power must therefore move through 120 times that space, namely twenty-five inches; but a lever or radius four inches long will describe a circle somewhat larger than this, and consequently such an engine would in theory be equal in power to the hydraulic engine we have been contemplating.

“But when the subject is viewed practically, the difference between the two engines appears to be very remarkable. All practical men know how very large a part of the force operating by means of engines is employed in overcoming frictions. Every one is aware of the extreme friction between solids, and the very slight friction which takes place between the parts of fluids. This is seen in the common expedient of oiling the pivots of wheels, and in the very gradual decay of motion in fluid bodies; while solids moving on each other stop at once, as soon as the force is diminished to a certain degree. The screw is an organ peculiarly liable to friction, and this friction is always much greater than the whole of the reacting force; for there are few instances where a screw will return from extreme pressure, when the agency upon the lever is withdrawn. It is also to be considered, that the whole force of the weight or resistance acts directly upon the face of the screw, at which the motion is required to take place. It has not been appreciated in what degree this resistance or friction increases with the weight. In lighter actions the simple ratio has been inferred; but under more severe pressures the two metallic faces extrude the greater part of the half-fluid matter between them, and appear, by the magnitude of their resistance, to be attached to each other by a process of the nature of cohesive attraction. For these and other reasons, it appears nearly impracticable to form any comparison between two engines so different in principle, but such as shall be deduced from immediate experiment of their effects. I am not in possession of numerical data to indicate the actual power of screw-engines or presses; which are perhaps the less necessary, because those who are the most interested in the success of an improvement like the present, are for the most part able to come at these without difficulty.

“In an engine of this kind, the diameter of the great piston was four inches, and of the smaller three-eighths of an inch; and the advantage given by the lever or handle was twelve to one. Above the piston of the great cylinder was applied a long lever, at one end of which was an axis, and at the other end a large scale to hold weights; it contained twenty hundred weight. The distance between the axis of motion of this lever and the part where it acted on the piston was six inches; and the distance from the same axis to the extremity where the scale was hung was 126 inches. Every hundred weight in the scale consequently pressed upon the piston with a force equal to twenty-one hundred weight; whence the whole pressure was twenty-one tons. It was easy to work the lever briskly with one hand, and each stroke raised the scale near one-third of an inch. Forty-seven pounds hung at the end of the lever, carried it down with a moderate swiftness of working; but a weight of only forty-three pounds remained in equilibrio, and did not descend. Now, as the true weight in theory was thirty-two pounds, it follows that less than one-third of the actual power was employed to give velocity and overcome all friction.

“It may be remarked, that the principal frictions in these machines must be at the circumference of the pistons, and that these do not increase in the simple, but in less than the subduplicate, ratio of the power. For if the diameter of the great cylinder were double, every thing else remaining unchanged, the surface of its piston, and consequently the power, would be quadrupled. But the friction would be only doubled, and that merely at the leathering of the greater piston.

“As the pressure in the experiment last mentioned amounted to 47·040 pounds upon the great piston of four inches in diameter, or sixteen circular inches surface, it amounted to 2940 pounds upon each round inch. But the medium pressure of the atmosphere on a round inch is near twelve pounds, consequently the action was equal to 245 atmospheres: and as each of these corresponds with a column of 34 feet of fresh water at a medium, the water in the cylinder was pressed in the same manner as if the whole column had been 8330 feet, or 1⅔ mile, long.

“Large presses of this construction are made with two pumps of 1¼ inch bore, and a cylinder of seven inches. These have been used in pressing hay and cotton for package; and, as I am informed, are effective in producing a greater condensation on the material with a much less application of moving power and consumption of time.”

The following description and figures are taken from Dr. Ure’s Dictionary of Arts, Manufactures and Mines, 8vo. 1839.

“The framing consists of two stout cast-iron plates a, b, which are strengthened by projecting ribs, not seen in the section, fig. 1. The top or crown plate b, and the base plate a, are bound most firmly together by four cylinders of the best wrought iron, c, c, which pass up through holes near the ends of the said plates, and are fast wedged in them. The flat pieces e, e, are screwed to the ends of the crown and base plates, so as to bind the columns laterally. f is the hollow cylinder of the press, which, as well as the ram g, is made of cast iron. The upper part of the cavity of the cylinder is cast narrow, but is truly and smoothly rounded at the boring-mill, so as to fit pretty closely round a well-turned ram or piston; the under part of it is left somewhat wider in the casting. A stout cup of leather, perforated in the middle, is put upon the ram, and serves as a valve to render the neck of the cylinder perfectly water-tight, by filling up the space between it and the ram; and since the mouth of the cup is turned downwards, the greater the pressure of water upwards, the more forcibly are the edges of the leather valve pressed against the inside of the cylinder, and the tighter does the joint become. This was Bramah’s beautiful invention.

“Upon the top of the ram, the press-plate or table h, strengthened with projecting ridges, rests, which is commonly called the follower, because it follows the ram closely in its descent. This plate has a half-round hole at each of its four corners, corresponding to the shape of the four iron columns along which it glides in its up-and-down motions of compression and relaxation.

“k, k, figs. 1. and 2., is the framing of a force pump with a narrow barrel; i is the well for containing water to supply the pump. To spare room in the engraving, the pump is set close to the press, but it may be removed to any convenient distance by lengthening the water-pipe u, which connects the discharge of the force pump with the inside of the cylinder of the press. Fig. 3. is a section of the pump and its valves. The pump m, is of bronze; the suction-pipe n, has a conical valve with a long tail; the solid piston or plunger p, is smaller than the barrel in which it plays, and passes at its top through a stuffing-box q; r is the pressure-valve, s is the safety-valve, which, in fig. 2., is seen to be loaded with a weighted lever; t is the discharge-valve, for letting the water escape, from the cylinder beneath the ram, back into the well. See the winding passages in fig. 4. u is the tube which conveys the water from the pump into the press-cylinder. In fig. 2. two centres of motion for the pump-lever are shown. By shifting the bolt into the centre nearest the pump-rod, the mechanical advantage of the workman may be doubled. Two pumps are generally mounted in one frame for one hydraulic press; the larger to give a rapid motion to the ram at the beginning, when the resistance is small; the smaller to give a slower but more powerful impulsion, when the resistance is much increased. A pressure of 500 tons may be obtained from a well-made hydraulic press with a ten-inch ram, and a two and a one inch set of pumps.”

In a Report addressed to the Commissioners of Her Majesty’s Woods, Forests, &c., in July 1839, as the result of an inquiry with reference to the selection of stone for building the new Houses of Parliament, it is stated the experiments relating to the cohesive strength of the stones, or their resistance to pressure, were made at the manufactory of Messrs. Bramah and Robinson, with a six-inch hydraulic press, the pump of which was one inch in diameter. According to trials previously made by Messrs. Bramah and Robinson, one pound weight at the end of the pump lever produced a pressure on the face of the cube [two inches square] equal to 2·53 cwt., or to 71·06 lbs. on the square inch; from this datum it may be estimated how immense the pressure is that can be obtained by this press, when the strength of a man is exerted at the pump. I have used the common book press with an iron screw to press printed paper, and I have also used a Hydraulic press of an estimated power of eighty tons: besides the greater expedition in pumping this press up than screwing the other down, I can state from my own observation, that the hydraulic press produced as great an effect upon the paper in three hours as the screw press did in a night, or at least fourteen hours. This may show the great superiority of this press over that which has been in general use in printing offices. The hydraulic press has fully accomplished in practice all that was expected from it, and has established for itself a high character, which it richly deserves.

HYPHEN.

A hyphen, marked thus (-), is employed in connecting compounded words; as, “Lap-dog, tea-pot, pre-existence, self-love, to-morrow, mother-in-law.”

It is also used when a word is divided, and the former part is written or printed at the end of one line, and the latter part at the beginning of another. In this case, it is placed at the end of the first line, not at the beginning of the second.—Murray.
