Abstract

297,661. Automatic Telephone Manufacturing Co., Ltd., and Simister, G., W. May 9, 1928. Multi-stage pumps; portable pumping-machines. -An electrically driven two-stage pump for vacuum-cleaning apparatus comprises two runners 10 and a fixed deflector 21 each built up of two saucer-shaped plates with intermediate blades. The deflector has a flange 24 which is clamped between the parts 25, 28 of the casing. The part 28 slides into the part 25 with a substantially air-tight fit. The driving motor is secured to the outer casing 33 by a bayonet joint fitting and being pressed home presses the inner casing up to a rubber ring closure 31.
