14,512. Barbey, C. Aug. 31, 1910, [Convention date]. Revolving-cylinder pumps; multiple-acting piston pumps; stroke, varying. - Relates to radial-cylinder pumps &c. with rotary or fixed cylinders, in which the piston stroke is varied by adjustment of an eccentric ring, or equivalent means, to which the piston - rods are connected, such adjustment being effected by liquid-actuated regulating-pistons. Referring to Figs. 1 and 2, three single-acting radial cylinders 1 on a rotary boss 2 are fitted with pistons 6 jointed to an eccentric ring 7. The eccentric collar 8 carries regulating-pistons 10, which are adjusted in cylinders 11 in the framing 3 by pressure fluid admitted at 12. The boss 2 has three ports 21, which register successively with admission and exhaust ports in a flat disk valve which is spring-pressed on the end 20 of the boss 2. This arrangement may work as a compressor, a pump, or as an engine which may be mounted directly on a vehicle wheel. Fig. 8 shows a modification, the piston-rods 5 being jointed to a collar 7 on a fixed axle 8, which is adjusted by the pistons 10. This combination may be used as a group comprising a primary pump and a secondary motor in the transmission of power by means of an incompressible fluid. Fig. 10 shows an internalcombustion engine coupled to a pump for power transmission. A represents the engine cylinders, B the air-compressing cylinders and C the fuel feed-pump cylinders, D the lubricating- pumps, and E the pump cylinders for the power transmission. The groups B, C, D, E are fitted with piston-stroke adjusting-devices of the kind described above with reference to Figs. 1 and 2. The fuel is fed by gravity to the pipe 34, then by centrifugal force along passages 33, 32 to the pump cylinder C, from which it is forced through ports 31 leading to a fixed annular passage 30 opening to the admission port 27 of the cylinder A. The suction to the cylinder B takes place through ports 35, the compressed air being delivered to the driving-cylinders through valved ports 26. The flat valve described with reference to Figs. 1 and 2 may replace the arrangement of ports 26, 35. The mixture is ignited by the heat of compression, the spent gases being swept out at 37. The eccentric collars 8 may be separate, or connected in sets. The cylinders are formed with water-jackets 39 as shown. Fig. 14 shows an adjustable-throw crank adapted to replace the eccentric strokeadjusting devices. The crank 49 is formed with pistons 50, which are adjusted with respect to the shaft 48 by pressure fluid admitted at 51. This device is applicable to engines with fixed or rotary cylinders.
