Abstract

534,401. Hydraulic power transmission. TOWLER, J. M., and TOWLER, F. H. July 5, 1939, No. 19537. [Class 69 (ii)] Hydraulic gear for giving a traversing motion at variable speeds to a machine tool comprises a constant speed pump A capable of supplying and exhausting the various spaces of a differential cylinder B, C containing a differential piston with a rod F operating the tool, the supply and discharge being controlled by a valve G, and check valves 15 being provided. The valve G, shown in Fig. 2 is operable to connect the cylinder spaces either with the supply pipe 1 or the suction pipe 3 of the pump. In modifications, the check valves 15 are omitted, and the pump supplies one or other end of the main cylinder B directly, in addition to its connection with the valve G, the ports of the valve being correspondingly altered.
