Abstract

508,648. Hydraulic machines. ROCKFORD MACHINE TOOL CO. April 1, 1938. No. 33578. Convention date, April 8, 1937. Divided out of 507,363. Drawings to Specification. [Class 69 (ii)] [Also in Group XXII] A hydraulic machine tool has a constant volume pump supplying a motor for reciprocating a ram or carriage under the control of a system including a valve determining the quantity of fluid supplied to the motor, another valve controlling starting and stopping of the motor, and a reversing valve for changing the direction of the ram or carriage. The machine embodiment is the same as that described in Specification 507,363.
