Abstract

531,971. Diaphragm pumps. SIMMS, F. R., and JOY, B. C. July 14, 1939, No. 20534. [Class 102 (i)] In a diaphragm pump a substantial central portion of the diaphragm is substantially rigid and functions like a piston, whilst the peripheral portion functions like a valve. The edge of the diaphragm may be thin, beaded, dished, or slotted, and the diaphragm may be made of rubber, with or without canvas, wire, or metal plate reinforcement. In the form shown, the centre of the diaphragm 10 is stiffened by plates 11, 12 and is operated by a spindle 7 which may be actuated by a cam or eccentric against spring action, or by a hand lever. As shown, the plates 11, 12 and the sections 2, 3 of the pump casing may be given a streamline contour, and upward movement of the diaphragm periphery 13 may be restricted by means of radial ribs 26 or a coiled spring. Two parallel diaphragms on a common spindle may operate in a single chamber or in two distinct chambers, or a number of circular or sector-shaped diaphragms in a single plane may co-operate with corresponding holes in a common suction section of the pump casing.
