Abstract

514,140. Vacuum-cleaner dust bags. LEHMKUHL, J. Nov. 26, 1938, No. 34516. Convention date, July 6. [Class 8 (ii)] The filter bag 4 of a vacuum cleaner, into which dusty air is drawn through a suction hose 3, is located in. a casing 1 formed with a hole 5 with a closure 6, so that when the hose is put out of action, by inserting its end in a cup 7, the valve 6 is held open and the air drawn in vibrates the bag and shakes the dust from its surface either by direct impact of the air on the bag, or indirectly, e.g., by operating a turbine 14, Fig. 2, bearing cams 18 acting in springs 21 to shake the bag. In a modification, a rack rod is attached to a heating spring and meshes with the pinion of a throttle valve in the air hole, so that the entering air forces the spring against the bag and simultaneously closes the hole, the spring then being returned by its elasticity and re-opening the hole.
