Abstract

26,998. Smith, J. W. Dec. 12. Vacuum cleaning-apparatus.-Flexible-diaphragm pumps are employed, operated directly by electric motors, preferably through a pair of eccentrics on opposite ends of the motor spindles. They are provided with flap valves in the form of thin metallic plates, and a motor and pump together preferably form a removable unit of the apparatus. The invention is described in connexion with a portable vacuum cleaning-apparatus as set forth in Specification No. 5759, A.D. 1909. The pump comprises a chamber 21 and a diaphragm 17 clamped at its outer periphery between the flanged end of the chamber and a ring member, and at its inner periphery between the flanges of a diaphragm follower 14. An electric motor 8 operates the pump through a pair of eccentrics on opposite ends of the motor spindle. The eccentrics are provided with ball bearings, and with rods which are integral with the eccentric straps and are directly connected to the diaphragm follower. Thin metallic plates 31 in the chamber and follower serve as suction and delivery valves. The apparatus may be used for pressure as well as vacuum cleaning.
