Abstract
123,654. Vickers, Ltd., and Duncan, T. S. May 8, 1918. Leakage-preventing devices.-A hollow impeller shaft B with radial openings B<2> into a chamber L' surrounding the shaft serves to conduct to the suction chamber of the pump any liquid which escapes along the shaft past the washers or packing-rings G, K. The cylindrical face of the cupleather G is forced centrifugally against the boss E' on the casing. The hat-leather washers K, M, are held between the flange E<3>, the loose sleeve L and the plate N which, with the ball-bearing J, is held in place by the cap E<2>. In a modification, the hat-leather M is replaced by a washer of T- section. The pump may be driven by an airdriven screw C, or from an engine shaft.
