Abstract

786,362. Reciprocating pumps. EKSTRAND, G. J. Sept. 16, 1955 [Sept. 16, 1954; Feb. 18, 1955], No. 26621/55. Class 102(1). [Also in Group XXX] In a hydraulic jack, oil is pumped from a reservoir 34 to the space 33 by a pump, the stepped piston 36 of which is guided by bores 49, 49a in a member which is screwed into the base 35, and has a bearing portion 50 for a rotatable collar 45 to which is pivoted the pump handle fulcrum link 43.
