ABSTRACT:
A unique hybrid shop-style and continuous-duty vacuum collector of reasonable size offers the advantages and capabilities of both specialized types, by substantially multiplying the conventional shop vacuum effective filter surface area, while preserving machine portability. The preferred embodiment employs three cylindrical pleated-paper filters to collect a wide range of sizes and weights of mixed dust and particulate debris. It is intended for both the hobbyist and the commercial shop operator who desire extended runs between filter cleanings. The filter cleaning mechanism efficiently breaks away the filtered accumulation, but protects the filter material from damage, by the carefully oriented application of mechanical shocks to generate cleaning oscillations of the filter surfaces only in their own planes. A mechanical sail interlock prevents additional filter damage by precluding accidental activation of the filter cleaning mechanism during the dirt collection process. The arrangement has special purpose applicability as a reliable filtering component in various gaseous systems, including those of low-gravity space.
