Abstract
381,398. Valve-discharge waterwastepreventers. HIGGINBOTHAM, J., 32, Linden Grove, Stockport. Dec. 12, 1931, No. 34474. [Class 26.] The valve-discharge water-wastepreventer described in Specification 104,558, [Class 26, Closets &c.], is modified by the provision within the cup b of an annular seating b<2>, against which the ball-valve E is raised, by a cam F to close the inlet and discharge the cistern ; in order to provide a small lift of the valve, only sufficient space is left between the ball E and the seating b<2> to allow the flow into the cistern when the ball rests upon the discharge-seating l. The cup b is provided with apertures b<3> communicating with the cistern a and has a flange b<1> secured between the discharge-pipe H and a flange upon the cistern ; and the cam F, which may be of the shapes shown in Figs. 4, 5, 6 and 7, is mounted upon a spindle K operated by a hand-lever M or by a foot-lever N<1>, Fig. 9, through a wire passing around a quadrant N, Fig. 8, having a spring or counterweight W. According to the Provisional Specification, the valve may be operated by two diametrically-opposite handles or a wheel capable of half a revolution.
