Abstract

622,649. Diaphragm pumps. SELFPRIMING PUMP & ENGINEERING CO., Ltd., GASKELL & CHAMBERS. Ltd., YATES, J. E. N., DAWSON, A. L. B., and MEREDEW, G. C. March 29, 1946, Nos. 9794 and 20382. [Class 102(i)] A diaphragm pump comprises two opposed pumping chambers each fitted with a diaphragm 25 attached to a guide piston consisting of two telescoping parts 16, 20 pressed apart by springs 22, 23, the part 16 being attached to a member 14 actuated by an eccentric 12. As the delivery pressure rises, the springs are compressed to reduce the amount delivered. Suction and delivery valves 55a, 55b respectively are in the form of flexible discs held at the centre and covering a ring of apertures. Each valve is accessible by removing a plug 58 and the valves are carried in covers 10 attached to the pump casing by hand nuts 46. The pump is suitable for dispensing beer and as shown the suction pipe 37 is connected by a tee-piece 60 to the suction valves. Both diaphragms may pump the same or different types of beers. Drip trays 3 are provided and all waste beer may be led to the pipe 37. An electric motor 2 drives the pumps through a reduction gearing and several pump casings may be mounted above the motor. An air vessel may be mounted on the delivery pipe 39 and a cock for priming may be mounted on the suction pipe 37.
