Abstract

246,039. Fisker, P. A. July 20, 1925. Filtering.-A vacuum cleaner is provided with a filter bag which extends into the dust container and filters the dust at its outer surface, the bag having means for turning it inside out without removal irom the container, so that the dust may be shaken off. The filter. Fig. 1, is secured to an upper ring 4 provided with a rubber coating 3 and clamped between the dust container 1 and fan casing 2. The bottom of the filter is clamped between two discs 6, 7, which may be starshaped, stays 9 connecting them to a ring 10 by which, when the container is removed from the fan casing, the bottom of the bag may be lifted to invert the bag and shake the dust into the container. The ring may be replaced by a cross,. bar, star, disc, or other device. Fig. 6 shows a filter in the form of a cone, the smaller end of which is inverted, the apex and the stays being secured to a perforated disc 10<a>, the disc being attached to the ring 4 by a bayonet joint &c. The stays may be replaced by a cylinder.
