Abstract

470,841. Hydraulic transmission of power. ROCKFORD MACHINE TOOL CO. Nov. 18, 1935, No. 31904. Convention date, Aug. 27. Drawings to Specification. [Class 69 (ii)] [Also in Group XXII] A reciprocating machine tool such as a shaping machine has a number of hydraulic motors for driving the tool-ram at different speeds, and the control system includes a first valve directing fluid from a pump to one of the motors to reverse the ram and a second valve further controlling the fluid directed to the remainder of the motors to render them selectively operable to drive the ram forwardly at a selected speed. The machine embodiment is the same as that described in Specification 465,809, [Group XXII].
