Abstract

329,928. Lary, A. Sept. 11, 1929. Filtering. - In a dust collector of a vacuum cleaner a filtering lining of wadding or the like f is arranged around a mounting of gauze or perforated sheet a and attached thereto solely by adhesion or by readily detachable fastening means h such as spiral springs. The base may be covered by a layer of wadding b. In a modification, the wadding is located within a tube which is split longitudinally. To fix the filter to the discharge pipe of a vacuum cleaner, a collar is fitted within the mouth of the filter and adapted to fit the discharge pipe.
