Abstract

723,465. Reciprocating pumps. LAWLER, AYRES & CO., Ltd. Aug. 7, 1953. [Aug. 11, 1952] No. 20175/52. Class 102 (1). [Also in Group XXII] A pump for 'supplying fluid to an actuating piston B of a pipe bending machine includes a pump cylinder E extending within a fluid reservoir F, a piston L reciprocated by a manuallyoperated lever P, and a spring- loaded outlet valve O. The piston L is formed with a longitudinal bore M<SP>1</SP> open at one end, through ports M and a filter gauze L<SP>1</SP>, to the reservoir F and provided at the other end with a ball N adapted to close the bore on the forward, operating, stroke of the piston. Manually controlled valves I and K, or in a modification a single valve, control the supply of fluid to the piston B.
