Patent GB-189719069-A (GB)
Title: Improvements in or Applicable to Fluid Pressure Motors.
Inventor: JOST CARL
Filed: 1897-08-18
Granted: 1898-07-16
Abstract: 19,069. Jost, C. Aug. 18. Single - acting engines; valve gear; driving-gear. -Consists of a form of engine suitable for being operated by steam, water, compressed air, or other fluid under pressure for automatically driving punkahs, sewing - machines, lathes, smiths' bellows, &c., or for pulling bells or the like. As applied to the driving of a punkah, the engine comprises a single-acting cylinder and piston with connections for raising the punkah in one direction, the opposing weight serving as a counterpoise for producing the return stroke. Fig. 2 is a vertical section through the cylinder b, showing the piston c, and Fig. 5 is a side elevation showing the lazy - tongs linkage through which motion is conveyed to the punkah by a line attached to the upper end. Admission and exhaust of the motive fluid above the piston are controlled by a piston valve e, which is moved upwards to effect admission by the main piston striking against its underside. At the end of the stroke it is moved downwards to close the admission and open the exhaust ports by pressure on the piston g transmitted by the pipe l, m from the lower end of the cylinder. The piston-rod may be hollow to admit air under the piston during the up-stroke. The effect of the linkage is to imitate muscular action in respect to its greater force at the beginning of the movement than in its continuation. In other applications a flywheel may be used.

Title: Improvements in Steam Generators and Motors applicable to Automobile Vehicles.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1899-11-11
Granted: 1900-11-10
Abstract: 22,526. Thompson, W. P., [Reibaldi, G., and Mazza, C.]. Nov. 11. Instantaneous generators; compound generators; feedwater, supplying.-Steam for use in the respective ends of the high-pressure cylinder of a compound engine is separately generated in distinct parts of an instantaneous coiled-tube generator, composed of two independent pipes coiled in a descending and ascending conical helix as shown in Fig. 8, the ascending portion of the coil serving as a superheater. The supply of feedwater to each part of the generator is effected by a separate pump, the two pumps being operated together by eccentrics and link motion adjustable to vary the stroke. To prevent the water from assuming the spheroidal state, the temperature of the generator is regulated by controlling the speed of the fan supplying air to the furnace of the generator. This is done by means of belt gearing with conical pulleys. To break up water in the generator which has assumed the spheroidal state, perforated conical baffles are inserted in the tubes of the generator, as shown in Fig. 4. The invention is particularly applicable in connection with automobile vehicles.

Incandescent lamps. - An incandescence rod 1, Fig. 7, made of a mixture of rare earths by moulding, has metal beads 3 embedded in its ends, which are preferably enlarged, to receive connecting-wires. For this purpose, the ends of the rod are first thickened by fusion in an arc, optionally first applying additional oxide paste, which may contain metal, or electrolytically depositing oxides on them. A bead of platinum or an alloy of this with copper, nickel, iridium, or other metal is then formed from a wire, on the end of the rod. in an oxyhydrogen flame, and the end heated in an arc until the metal bead sinks into it. The bead is next fused by the oxyhydrogen flame sufficiently to receive the end of a connecting-wire. In a modified process, the connecting-wire is soldered directly to the end of the rod, previously enlarged with paste and baked, using one of the above-mentioned alloys in an oxyhydrogen flame. A long rod may be supported at one or more points between its ends by applying small paste projections, to which wires 10, Fig. 14, are attached by the above-described methods.

Abstract: 13,262. Feix, G. July 23. Brakes.-An air brake, for railway and like vehicles, is supplied with air from a main reservoir a through a pipe 1 controlled by a valve b having ports m, n. This valve also controls two mains 2,3, and a branch 4 open to the atmosphere. Each coach carries a brake cylinder c, having a piston d connected with the brake normally held off by a spring p. The cylinder is connected near each end with a distributing-cylinder f, containing two pistons g, h carrying valves i, k. Pipes 5, 6, 7, 8, and 9 are provided as shown, and by means of a valve l the pipes 2, 3 can be put in communication with the passages 7, 8 or vice versÔ. Normally both of the pipes 2, 3 are in communication with the brake cylinder, or the pipe 2 is closed and the brake is off. By putting the pipe 2 in communication with the atmosphere, the pistons g, hare operated so as to put the left end of the brake cylinder in communication with the atmosphere, while the right-hand side of the piston is subjected to air pressure and the brake applied. A non-return valve q prevents the release of the brake if the train is severed or the main fractured. The brake may be applied, in cases of emergency, by opening a pet valve r. When the brake is to be worked with one main only, an extra passage, having a non-return valve v, is provided. In a modification, in which only one side of the brake cylinder communicates with the distributing- valve, the pipe 8 communicates with an auxiliary air reservoir connected by a pipe to the lower end of the cylinder f. In this case the valve k controls the passage leading to the brake cylinder, while the valve i controls the air outlet.
