Abstract
750,750. Suction cleaner filter bags. HOOVER, Ltd. May 14, 1954 [May 18,1953], No. 14267/54. Class 8(2). [Also in Group XVII] A disposable paper filter bag 30, Fig. 1, for a vacuum cleaner has two sets of longitudinal pleats 33, Fig. 2, extending the full length of the bag between the edges of opposite webs 31, 32 and the inlet opening is formed at one side by one web 32 and at the other side by the web 31 and all the pleats 33. The web 32 is wider than web 31 and the outer and inner fold lines 35, 34 are offset progressively inwards in echelon fashion as shown in Fig. 3. The inlet end 43 of the web 32 is cut straight whereas the ends of the pleats 33 web 31 and a dirt trap strip of cardboard 47 are curved and are secured together to assist the introduction of a filter adapter tube 21 having a groove 24 in which the bag is held by a garter spring 25. When inflated the bag distends below the adapter tube due to the disposition of the pleats and forms with the trap 47 a dirt collecting pocket. An appearance bag 29 protects the bag 30, and the adapter 21 is connected by a flexible bellows 22 to the fan exhaust outlet 12.
