Abstract
815,709. Suction cleaner filter bags. TORNADO A. G. Nov. 7, 1957, No. 34675/57. Class 8(2). The neck 1 1 of a suction cleaner dust bag 1 e.g. of paper is secured e.g. by adhesive to a tube 6 having at its outer end an inturned bead 6 1 adapted to cooperate with a threaded portion 113 of the exhaust duct 5 of the cleaner. The said threaded portion 113 comprises the outlet end of a tapered sleeve 11 and the tube 6 is of cardboard which bites on to the threads. The inner end of tube 6 carries a collapsible pocket 2 having side slits 8 1 , 8 2 through which pressure air passes into the bag 1 and a cavity 10 into which settles dust. A protective envelope 4 is supported by a frame 3 having ends secured by a locking ring 18 in grooves cut in a cylindrical portion 12 of the outlet 5.
