Abstract

479,126. Vacuum cleaners. HOOVER HOLDING CO., Ltd. (Hoover Co.) July 24, 1936, No. 20539. [Classes 8 (i) and 8 (ii)] The degree of clogging of the dust bag of a vacuum cleaner is indicated by a device F responsive to the pressure on the exhaust side of the fan. The device shown comprises a bellows operating a pivoted indicator G, the parts of which are successively moved opposite an inspection aperture. It is carried by a ring C between the fan and the dust bag. The signal may comprise a lamp either lit or extinguished at a desired pressure. The Provisional Specification states that a trigger-actuated visual indication or a sound indication may be provided.
