Abstract

823,800. Suction cleaning apparatus. HEMSCHEIDT H. [trading as HEMSCHEIDT MASCHINENFABRIK H.]. Nov. 1, 1956 [Nov. 5, 1955], No. 33369/56. Classes 8(1) and 8(2). A rock dust collecting container 2 disposed beneath a suction creating unit 20 and dust separating means located in a detachable container 1 and from which separated dust falls into the container 2 has a funnel-shaped inlet 5 and a system of orificed pipes 8 .... 12, 15 and 16 which on detaching the container 1 are adapted to be connected by a union 7 to a water supply pipe whereby accumulated dust is removed as mud through an outlet 13 adjacent the base 6 of the container 2. The suction unit 20 comprises a compressed air actuated injector and dust is separated by a nest of filters 21. Specification 751,821 is referred to.
