ater or steam, acting in the reverse direction to a refrigerant, would be adapted to increase the effect of the air as an expansive motor. Alternate expansion and contraction was the whole principle of the M. I. Brunel Gas-Engine Patent, England, 1804. Heated carbonic-acid gas is preferable to air for developing a large force in small space. See gasengine. See also air-engine; compressed-air engine; air as A water-elevator. Air′--cone. In marine engines; to receive the gases which entirs communicating with the cylinder on the respective sides of the piston; the air in said reservoir being alternately heated and cooled to change its expansive force and thus reciprocate the piston. This was the form of Brunel's engine, British, 1804; and Stirling's, British, 1827; and Peters's, 1862. 4th. Those engines in which water or steam is mingled with the air to moisten it and keep the working parts from abrasion; in some cases being introduced in quantity to be positively co-opera
oons were also employed by the French in the Italian campaign of 1859, at Solferino; and subsequently, during our own civil war, a small corps of balloonists was attached to the Army of the Potomac. The celebrated French chemist, Gay Lussac, in 1804 reached the hight of 23,040 feet, and carried up with him the necessary means for making scientific observations on the character and properties of the atmosphere at that great hight. This was for many years considered the most remarkable balloonnd pitching motions of a ship, and has a contraction at the bottom of the tube to obviate oscillations of the mercury. It was introduced about the year 1698-1700. The invention of the aneroid barometer is attributed to Conti, 1798, or to Vidi, 1804. In the aneroid barometer (which, as its name implies, has no liquid) the pressure of the atmosphere is exerted upon an elastic metallic diaphragm above a chamber partially exhausted of air. The motions of the diaphragm, due to changes of press

The flotilla was constructed for the invasion of England by Bonaparte; the floating carcasses wliding bevel guide. He also invented making circular saws of segmental plates. One was patented in England by Trotter, 1804. Brunel's veneer-saw, 1805-1808. The double saw-mill shown in the illustration is of the Blandy pattern, selected from Con′greve-rock′et.

with the space above the piston of the larger cylinder, where it was used expansively. Hornblower's engine occupies one notable point in the history of the steam-engine, but was not adopted to any great extent. Wolf, in his English patent of 1804, improved the arrangement, and his may be considered the progenitor of the numerous compound and duplex steam-engines which have proved so successful. See also Tippett's English patent, 1828. This form of engine is extensively used in France, has a succession of buckets on an endless chain, which traverses on a frame whose lower end is vertically adjustable so as to regulate the depth at which it works, like the French chapelet. It was first successfully used in England by Huges in 1804, who succeeded, after repeated trials, in making a machine, costing $40,000, which raised 2,000 tons per day from a depth of water of 30 feet. The machine is driven by a steam-engine through the intervention of gearing, steadied by a fly-wheel.
oduced by the combination of the hydrogen of the gas and the oxygen of the air would suffuse the curtains of a room with moisture, and would render it necessary to wring out the curtains and other linen furniture of the apartments on the morning subsequent to the illumination by the burning of the coal smoke. — Monthly Magazine, London, June 1, 1805. In 1803 – 4, Winsor lighted the Lyceum Theater and took out a patent for lighting streets by gas. He established the first gas-company. In 1804 – 5, Murdoch lighted the cotton-factory of Philips and Lee, Manchester, the light being estimated as equal to 3,000 candles. This was the largest undertaking up to that date. In 1807, Winsor lighted one side of Pall Mall, London; the first street lighting. Westminster Bridge was lighted in 1813. Houses of Parliament, London, in the same year. Streets of London generally, 1815. Streets of Paris, the same year. James McMurtrie proposed to light streets of Philadelphia, 1815. <
aps, we should state the work of the man who has done more than any other one man to make the locomotive what it is: Richard Trevethick of Merthyr Tydvil, in South Wales. He had not got over the idea of the necessity for something more than the weight of the engine to give tractional adherence to the rails, and used a cog-wheel and rack rail. (See locomotive.) He used a blast of exhaust steam in the chimney, patented his locomotive in 1802, and it was in use on the Merthyr Tydvil Railway in 1804. Trevethick and Vivian patented the application of high-pressure steam to engines. Trevethick is described in the Catalogue of the South Kensington Museum, London, as the inventor and constructor of the first high-pressure steam-engine, and of the first steam-carriage used in England. Blackett improved on Trevethick, and used smooth wheels on a plate-way. The multitubular boiler is stated to have been used by Rumsey, and subsequently, in 1790, in England. It was used by John Cox Stev
rn. The lace-making machine for weaving the real twisted lace, like that made on the pillow, was invented by Heathcoat, 1804. The groundwork of the invention is to extend those threads which form the warp of the lace in parallel lines, and dispes to the mile, was finished by Sir Hugh Middleton, and the water was distributed by wooden mains and leaden branches. In 1804, cast-iron pipes were substituted for the wooden mains. Lead-pipe is made by casting, drawing, pressing, and rolling. Lead—pipe Tin′ning. The first attempts in this direction were by Alderson in England, who patented his invention in 1804, which consisted in putting an interior casing of tin pipe within the leaden one. Dobbs, in 1820, gave a coating of res In 1789, Mr. Greathead of South Shields invented his boat, which proved so successful that it is said that previous to 1804 nearly 300 lives had been saved through its instrumentality near the mouth of the Tynemouth Haven. This boat was about
first. On sawing them through, the exterior coat of soft metal is perfectly distinguishable from the remainder. The inventor of the process of rendering articles of cast-iron malleable was Samuel Lucas of Sheffield, by whom it was patented in 1804. As described in his specification, his process was nearly identical with that above described, except that the castings were placed directly in the furnace, instead of being inclosed in boxes. The Siemens regenerative gas furnace is largelyin the stiles and sets the machine in motion, when it does its work, and, having done it, stops. Machine for boring and mortising stiles of blinds. Fig. 3240 shows Brunel's mortising-machine made by Maudslay for the British Admiralty, about 1804, for mortising the shells of ships' blocks. The series of machines for making blocks is described under block-making machine. In the mortising-machine represented, the blocks of wood are clamped in a sliding bed and the mortises are made by verti
-acting paper machine on Robert's plan. He had been employed by Didot and gamble for this purpose, and appears to have made great improvements on the original. 1804. Henry and Sealy Fourdrinier of London purchased the patents of Didot and Gamble. From the improvements made under their auspices and their manufacture of it on afirst to produce a photograph, in the artistic and technical sense of the word. Dr. Thomas Young, the originator of the undulatory theory of light, published in 1804 some important researches on the chemical rays. In 1809, Gay Lussac and Thenard made the exceedingly valuable observation, that a mixture of chlorie and hydrogevanes or wings, and more specifically known as the screw-propeller. The first use of the propeller was by Stevens, of Hoboken, who used twin-bladed screws in 1804. See screw-propeller. The bladed screw-propeller was brought forward by Ericsson in 1836, and the spiral screw in the dead-wood was patented by F. P. Smith.

Stevens navigated his propeller by sea to the Delaware chain-stitch, is Duncan's machine, English. No. 2,769, of 1804. It had a number of hooked needles, which passed through t latter was used to run a saw-mill for a long period. In 1804, John Stevens, of Hoboken, N. J., built a steamboat at his n John Stevens, of Hoboken, had a flueboiler on his boat in 1804. See screw-propeller, pages 2070, 2071. Trevethick had et Metiers at Paris. Cugnot was born in 1729, and died in 1804. In 1769, Moore, a London linen-draper, patented an inveailway-engine employed in the vicinity of Merthyr Tydvil in 1804; of mining-engines and machinery and coining apparatus for imary cylinder. Woolf very much improved this idea about 1804. See double engine; compound engine; duplex engine. Th
