Abstract
28,087. Anders, A., and Beckmann, R. Dec. 10. Vacuum cleaning-apparatus.-A portable hand apparatus comprises a wheeled frame a, Fig. 1, carrying an oscillating double - acting pump d operated by a crank driven by spur gearing from the wheel axle. The nozzle g, Fig. 3, has two passages connected by flexible tubing e, f with the discharge and suction orifices of the pump, so that a volume of air is in continuous circulation within the apparatus, being discharged through one nozzle passage and withdrawn, laden with dust, through the other. The air is filtered in a suitable chamber j. For removing dust from hangings &c., additional nozzles and long connecting - tubes are employed ; a hand-operated crank is attached to the wheel axle, the entire apparatus being then inverted and supported by the handle and a strut k carried by the frame, Fig. 4. The connecting- tubes may be led to a common point where a valve &c. may be placed to divert the circulating air from the nozzles not in use. In modified arrangements, the frame may be replaced by a flat box, which supports the pump or bellows and serves as the filtering-chamber.
