Abstract

784,606. Vacuum cleaners. ELECTROLUX CORPORATION. April 12, 1956 [Aug. 31, 1955], No. 11131/55. Classes 8(1) and 8(2). Automatic release of a latch 58, Fig. 1, holding a pivoted cover 36 having a central dust-laden air inlet 40 against the open end 26 of the cylindrical casing 10 of a motor-fan suction cleaner of the inside bag type is effected by displacement of a diaphragm 72 and a pin 70 carried by the cover 36 by vacuum on the fan side of the filter bag 118 being transmitted through tubes 84, 112 and past a valve 104 when the latter is unseated by a flexible diaphragm 80 having one side connected by a tube 82 to the dust-laden air inlet 40 and the other side connected by the tube 84 to the fan side of the dust bag ; the valve 104 and diaphragm 80 also being carried by the cover 36. The valve 104 is held closed by a spring 106 the tension of which is adjustable by a knob 102, and release of the cover 36 affords release of a slide 145, Fig. 6, which opens the motor switch 130. A handle 152 has a finger 106 on which may be mounted cleaning tools and the rear end cover of the casing 10 provides a cord reel 194. The dust bag which may be of paper or cloth is surrounded by a perforated metal casing 20 and a final disc filter 192 is located adjacent the rear end cover. Reference has been directed by the Comptroller to Specification 764,512.
