products of combustion are passed through the working-cylinder, the induction and eduction valves being worked in the usual manner. Wilcox, May 16, 1865. This engine is substantially on the principle of the engine of Sir George Cayleys (about 1830). The fire is fed with air, under pressure of a pump, and the volatile products of combustion are passed through the working-cylinder. Messer's air-engine. With each descent of the piston air is drawn through the inhaling valve E, and fillso the water. A bridge arched in this manner is said to have been built near Florence as early as 1530, but their general introduction dates no farther back than the era of the commencement of railroad construction, about or a little previous to 1830. Skew arch. The ordinary method of building a skew arch (Fig. 390) is to make it a portion of a hollow cylinder, the voussoirs being laid in parallel spiral courses, and their beds worked in such a manner that in any section of the cylinder

We find cricket first mentioned in 1719. Croquet was introduced into England from Germany in 1830; its popularity in America hardly dates back more than a decade. 2. (Projectiles.) A missile1841.

eing comparatively short, have pedestals for the axle-boxes attached directly to the bed-frame. The cars constructed in 1830 for the Liverpool and Manchester Railway, England, had four wheels, but no springs; the bodies consisting of sills, to whirs driven by the power of the locomotive. A device similar to that described in Vignoles and Ericsson's English patent, 1830, was adopted by fell in the Mount Washington Railway, whose steep gradients could not be ascended by the ordinary means. Hans Holbein drew portraits in crayon in 1540. Sir Thomas Lawrence excelled in this style of portrait-painting, 1800 – 1830. 2. (Lithography.) A composition formed as a pencil, and used for drawing upon lithographic stones. It is of a soapyeylon graphite ever brought to the United States, and the first known use of foliated graphite for crucible making. About 1830 Mr. Dixon adopted the Dutch pipe-clay to mix with the Ceylon graphite. To ten pounds of ground graphite, seven pounds of

A partial vacuum is obtained in that part of the roller on which the paper rests. Dan′dy-brush. A hard, whalebone-bristle brush. Dan′dy-horse. A velo tried by the celebrated Bernoulli, afterwards by Genevois, a Swiss clergyman, about 1757; then by Earl Stanhope about 1803. It was used on the river Thames about 1830. Dumb-bells.

ass of patterns in calico-printing, is performed by a diamond etching-point on the varnished roller. The points are moved by elaborate machinery, and the effect is analogous to that of the eccentric and rose-engine lathes. 2. An apparatus on the principle of the pantograph, but provided with a cutting device and machinery for causing pressure upon the surface to be engraved, so as to produce lines similar to those made by hand with the graver. Collas (English patent) engraving-machine, 1830. Electro-magnetic engraving-machine used in Germany, 1854; in America, 1858. Guerrant and Field's engraving-machine was patented in 1867, and was in operation in New York City during the year 1868. To engrave by means of this machine the operator sits with a copy of the drawing, photograph, or whatever design is to be engraved, directly in front of him. A small pointer rests upon the drawing, and the whole operation consists in moving the pointer over the several lines of the copy. The

water passes by a hose to a nozzle. C is the English form of hand fire-engine which has brakes h on side-levers p. The suction is united at f, and the discharge is at m; n is the air-chamber. Steam-power for extinguishing fires was in use in manufacturing establishments many years before it was employed on portable machines. Every factory of any pretensions had its steam-driven pump, with hose and other attachments calculated to reach every portion of the establishment. About the year 1830, Captain Ericsson, then of the firm of Braithwaithe and Ericsson, London, England, built and exhibited a portable steam fire-engine. In 1842 or 1843 he produced a similar engine in New York City, and it was tested, but never brought into regular service. The engine delivered 9,000 gallons an hour to a hight of ninety feet through a 7/8-inch nozzle. It was ignited at the station, and drawn by horses to the fire. The time occupied in getting up steam was eighteen minutes. The motion of the

from an eminent member of this firm, the following record of improvements in the glass trade, during the last fifty years:— 1. The substitution, about the year 1830, of carbonate of soda as the alkaline ingredient in glass in the place of kelp, and subsequently, for crown and sheet glass, of sulphate of soda in the place of cag the glass of unequal texture and consequent refracting power. In this consisted the principal difficulty in obtaining object-glasses of large size. So late as 1830, the largest object-glasses of satisfactory performance which were produced did not exceed five or six inches in diameter. Previous to this, however, Guinand, a m by the engine, the combination of wheels and center-rail forming the means of ascending gradients, is first found in the English patent of Vignolles and Ericsson, 1830. Sellers's United States patent, 1835, has a similar device, and it is also used by Fell on the White Mountain Railroad in New Hampshire and the Mt. Cenis Railw

ines the substance which shall be used. Scott's English patent, 1828, describes a mode of catching the deposit which forms the incrustation by placing pans or trays in the boiler; these intercept the falling deposit. Taylor's English patent, 1830, has a sedimenttrough the length of the boiler, and forming a narrow chamber below the same, out of contact with the fire. The contents of this chamber are occasionally blown out, carrying the sediment. To avoid the expenditure of space in sta exterior to the dial-plate of the telegraph. Following the discovery of Oersted, Ampere in 1820 suggested that the needle moved by the galvanic current should be used for conveying signals, and the idea was elaborated in lectures by Ritchie in 1830. Baron Schilling, in Russia, in 1832, contrived a complicated instrument on this principle, in which a separate circuit and needle was employed for each letter and numeral, 36 needles being employed, each being excited by a current of electri

late shuts over a flattened portion of the key-shank to prevent its being turned by an outsider. A pawl acts as a detent for the escutcheon. Key′hole-pro-tect′or. Mitchell and Lawton's English patent, 1815, has a revolving curtain for closing the keyhole. Key-guard. Day and Newell's parautoptic lock has a revolving ring or curtain, which moves with the key and shuts the hole, so that wires and tools cannot be introduced alongside the key. Mordan's keyhole protector (English), 1830, has a short pipe which, after the door has been locked, is thrust into the keyhole; attached to the pipe is a small lock so contrived that, on turning its key, two lancet-shaped pieces fly out laterally and bury themselves in the wood. The escutcheon cannot be removed until the small key has reacted upon the small lock; and until this removal has taken place, the large key cannot reach the keyhole. Key′hole-saw. A long, thin saw. See compass-saw. Key-mod′el. A mode of modeling

the fetlock or foot by interfering or overrcaching; that is, by striking the fore or hind foot against its fellow as they pass each other in motion, or striking the heel or shoe of the front foot by the toe of the hind foot or shoe. 2. To prevent the cutting of the knees in kneeling or falling forward on to the knees. 3. To prevent the unhairing or abrasion of the hide by hopples. See hopple. Rotch's flexible elastic horseshoe, patented in England in 1810, and with improvements in 1830, consisted of a sheet-metal sole and a body of india-rubber made to fit over the crown and upon the pastern. The immediate purpose of the caoutchouc cover was to hold on the sole to which a regular bar-shoe was riveted, if necessary. The india-rubber covering, in the case of interfering horses, was prolonged over the fetlock in order to keep the hide from abrasion by the blows of the other foot, or from being barked or cut by the toe of a hind foot in horses addicted to overreaching.
