Abstract

1462873 Reciprocating pumps Z BIEGANSKI and H BIEGANSKI [trading as AB ENG CO] 22 April 1974 [27 April 1973] 20028/73 Heading F1A A pump for operating the ram 36 of a crimping or cutting tool comprises a piston 15 reciprocated by hand-operated levers 33 acting via toggle links 34 and a sleeve 32 to give a fast, initial, low-pressure movement and a slow, final, high-pressure movement. Piston 15 draws liquid into the pumping chamber from a reservoir 17 enclosed by a rubber sleeve 16, via points 20, 19 and ball-valve 22, and delivers to ram chamber 23 via ball-valve 25, and adjustable, pressure-relief valve 28 controls connection 26 between chambers 23 and 17, another connection 27 being controlled by a ballvalve 29 operated by a rod 30. Brackets 35 limit outward movement of the levers 33. The tool may comprise a pair of relatively movable members dismountable as a unit from the casing 24, e.g. using a bayonet coupling, one of the members being actuated by the ram 36.
