Abstract

211,336. Hoffmann, M. G. Feb. 7, 1923. Actuating by foot power; lever-actuated pumps ; double-acting bucket pumps ; regulating delivery by by-passes; valves, arrangement of.-A pump, suitable for supplying pressure liquid to hydraulic presses, winding engines, &c., comprises two coaxial buckets operated by a lever 7 overhanging the cylinders and provided with two pedals 8 and a short arm 5 engaging the buckets. Liquid is drawn from the chamber 1 through the bucket valves 10, and is delivered through passages 14 and valves 12 to a chamber 13 provided with a delivery pipe 15 and a by-pass valve.
