Abstract
486,012. Lathes &c. HASSE & WREDE GES., C., and STUDINGER, E. Nov. 25, 1936, No. 32247. [Class 83 (iii)] In a hydraulic feed for a lathe &c. an adjustment device is provided for keeping the feed per revolution of the spindle constant, the gearchanging device for the main spindle being so coupled with the regulating device of the fluidpressure feed pump as to enable the latter to be adjusted independently of the coupling between the gear-changing device and the pump. The gear-changing handle a may be connected by a rack-bar n through a pinion o with another longitudinal bar or rod p rotatably connected with a further rod g which is screwed into a rack-bar i controlling the valve of the fluid pressure feed pump b. A handle d, carried by the saddle c, has a splined connection with the shaft g through a worm and worm wheel, thus enabling the pump valve to be adjusted to vary the feed of the saddle independent of the spindle speed control, but the connection between the latter and the pump ensuring that with a given setting the feed per spindle revolution remains constant.
