Abstract

303,473. National Automatic Tool Co., (Assignees of Galloway, R. M.). Jan. 4, 1928, [Convention date]. Hydraulic transmission of power.-Hydraulic operating-means for machine tools comprises a hollow distributing valve given a step-by-step movement and a regulating valve of the kind described in Specification 292,967, [Class 135, Valves &c.]. The regulating valve member 106, Fig. 11, has a bore 115.and a slot 116, the flow through the slot being regulated by movement relative to a shoulder 117 on a bush 101. The apparatus shown in Fig. 6 comprises a cylinder movable over a fixed piston 58, under the control of a hollow distributing valve 68 and the regulating valve in a casing 70. The distributing valve is initially set by fluid pressure means and normally tends to move to the right, this movement being controlled by notches 90 cooperating with a latch member 74 operated by stops 77, 78 carried by the hydraulic cylinder. Specifications 301,481 and 310,288 also are referred to.
