Abstract

533,696. Centrifugal pumps. PARTRIDGE, WILSON & CO., Ltd., and WILSON, H. G, A. R. Nov. 15, 1939, No. 30140. [Class 110 (i)] An electrically-driven apparatus for pumping liquids in which a switch for controlling the current to an electric motor which drives the pump 19 is actuated by a float 33 influenced by the liquid, the electric motor 11 and the switch 29 are enclosed within a liquid-tight chamber 3 and the switch is actuated automatically by the float from outside the chamber. In the form shown, a closure disc 5 is secured by a watertight joint 10 in a cast casing 1 to provide a float housing 2 below a bell-shaped chamber 3, the housing 2 having one or an opposite pair of grating-covered openings 6 terminating below its top so as to provide an air-trap. The spindle 13 of an induction motor 11 is directly connected by a flexible coupling 23 to the spindle 21 of a centrifugal pump 19 the inlet 24 of which is covered by a filter 25. The float arm 34 is pivotally connected by a rod 37 to the tumblerswitch lever 32, the rod 37 passing through a rubber or other waterproof diaphragm, sleeve, or bellows 39 which forms an air-tight connection between the chamber 3 and the air trap. The casing 1 is fitted with a carrying ring 42, and it may be completely submerged in the liquid to be pumped, the chamber 3 being provided with one or more apertures closed by air-tight covers.
