Abstract

905,474. Suction cleaner filters. SIEMENSELECTROGERATE A.G. Sept. 28, 1960 [Sept. 30, 1959], No. 33371/60. Class 8(2). A device for indicating when the filter of a suction cleaner is blocked consists of a ball 9, free to move vertically inside vertical tube 8, through which tube a small proportion of the clean air passes. Under normal operation the flow of air through the tube is sufficient to force the ball to the top of the tube, where it is visible to the operator. When the filter is blocked and the air flow is reduced, the ball falls and is no longer visible. The ball may be replaced by a piston from which extends a pin, the pin being visible only when the filter is not blocked. The piston may be restrained by a coil spring.
