Abstract

510,985. Vacuum cleaners; filtering air. THWAITES, A. C. Aug. 4, 1938, No. 14659. [Classes 8 (i) and 8 (ii)] [Also in Group X] The dust bag of a vacuum cleaner is removed' and replaced by a filter or purifier 5 containing charcoal, held in the position occupied by the dust bag, so that the cleaner can be used to remove toxic gases and smokes from an atmosphere. The filter shown comprises alternate beds of charcoal and wool separated by gauze partitions, with layers of linen gauze at the inner end, in a corrugated casing. By attaching a cover and hose, air may be drawn from the outside of a building into a room.
