550,781. Vacuum cleaner dust bags. HOOVER, Ltd. July 21, 1941, No. 9188. Convention date, Sept. 7, 1940. [Class 8 (ii)] To facilitate the manoeuvring of a suction cleaner below furniture, the dust bag is formed with a longitudinal web 7, or longitudinally spaced webs, which resist inflation and provide a longitudinal recess to accommodate the handle which carries the bag. The web may be spaced from the inlet to provide an entrance to the separate sections. As a modification, the bag may be formed of two parallel tubular sections 9, Fig. 4, stitched together.
