Abstract

489,193. Hydraulic transmission of power. JUNG, K., (trading as JUNG MASCHINENFABRIK, K.). March 24, 1937, No. 8705. Convention date, March 27, 1936. [Class 69 (ii)] [Also in Groups XXIII and XXII] In hydraulic apparatus for effecting the transverse feed of the tool table or the grinding wheel in machine tools or grinding machines, the cross-slide b is operated by a hydraulic motor e under the control of a shut-off valve p connected between the pump P and the motor, the valve being opened by an adjustable stop t, t<1> carried by the longitudinal slide a. The amount of movement of the slide b is determined by the length of the stop. A manuallyoperated reversing valve v is provided. In a modified form, the valve is connected in a byepass circuit so that liquid is supplied to the motor e if the valve is not depressed by the stop. The valve could be controlled from a separate motor instead of from a moving part of the machine, but in any case the operation of the apparatus is such that each stroke of the hydraulic motor is performed in a series of intermittent steps.
