Abstract

256,420. Hathorn, Davey, & Co., Ltd., and Lupton, H. R. Sept. 25, 1925. Crank-actuated pumps; multiple-acting piston pumps.-The three plungers of a three-throw pump are replaced by three pairs of smaller plungers 8, 12, 9, 13, 10, 14, each pair working in opposite directions in opposed cylinders. The rear side plungers 8 - - 10 are actuated directly by cranks 2, 4, 6, the others by cranks 3, 5, 7 through crossheads 15, 16 and side rods 17. The pairs of cranks 2 - - 7 are 180‹ apart. Each pair of opposed cylinders use the same inlet and delivery valves 15, 20. The crank-shaft is driven by a shaft 25 through pairs of single helical gear wheels 24, 23. The shaft 25 is mounted in bearings 26 so as to be free to move slightly in the direction of its axis.
