Abstract

265,361. Hodgson A. E., and Lamplough, F. Jan. 19, 1926. Crank and lever-actuated pumps; stroke, varying-Variable-stroke mechanism for operating a pump comprises a crankshaft 28 or the like conected by two parallel plates 20 and driven through gear wheels 19, 32 by a shaft mounted in the pump casing 10. The small end 30 of the connecting-rod 29 driven by the shaft is pivoted to links 32 swinging on pins 33 mounted in the plates 20, and is connected by a link 34 to the end of a lever 35 which swings on a pin 36 and is connected at the other end to the pump plungers 37. The plates 20 are angularly adjustable round the axis of the driving wheel 19 by hand or automatic means to vary the angle between the path of the pin 30 and the path of the lower end of the lever 35 and thereby vary the throw of the lever between zero and a maximum. When the pins 33 are coaxial with the lower end of the lever, the latter does not move, and when the plates 20 are adjusted to bring the links 29, 34 into alignment, the movement is a maximum. The lever 35 may drive two pump plungers, and a duplicate mechanism may drive another pin. The plates 20 may be adjusted by the delivery pressure of the pumps.
