Abstract

744,345. Centreless grinding. SCRIVENER, Ltd., A. Nov. 8, 1954 [Nov. 7, 1953], No. 30866/53. Class 60. A hydraulic work feed mechanism for a centreless grinding machine includes a piston valve c operated by a hand lever a against the resistance of a spring j, the valve having an elongated V slot c<SP>1</SP> so that its position determines ,the rate of flow of fluid through the valve. Ports f, g are connected to a pump while parts b<SP>1</SP>, b<SP>2</SP> are connected to opposite ends of a cylinder d having a piston d<SP>1</SP> which through a rack and pinion k. l rotates a screw member e within the limits determined by stops m. The member e is connected to the workpiece on a carrier therefor and is provided with a hand wheel n When the valve c is depressed by the hand lever a fluid flows through ports f, b<SP>1</SP> to the left end of the cylinder d and escapes through port b<SP>2</SP> and slot c<SP>1</SP> from the right end the extent to which the valve is depressed determining the rate of escape and hence the speed of movement of the member e.
