431,543. Waste valves for lavatory basins &c. CORNELL, E. S., 17, Campbell Lane, Larchmont, New York, U.S.A. Sept. 25, 1934, No. 27489. [Class 135] A waste valve particularly for use with lavatory basins, tubs, &c., comprises a rotatable valve member 17 of generally spherical shape with a passageway therethrough so that in one position of the valve 17 the passageway registers with an annular valve seat 18<a> to allow fluid to flow therethrough and in another position an imperforate part 17<a> of the member 17 bears against the seating 18<a> to stop the flow of fluid, the member 17 being displaceable towards and away from the seat 18<a> and resiliently urged towards the seat. The seat 18<a> is formed on a part 10<b> shaped to the opening in the basin 13 and screwed into the valve-housing proper 10<a> which is secured to the basin 13 by a nut 14. Two elongated holes 20 in either the part 10<b> or the part 10<a> or a ring clamped between them receive the symmetrically-disposed trunnions 19 of the valve member 17. A ring 21<a> of spring steel is clamped between the parts 10<a>, 10<b> and has curved depending tongues 21 which engage the surface of the member 17 to press it towards the seat 18<a> and also serve to hold it frictionally in any position to which it has been rotated. The imperforate part 17<a> of the member 17 is substantially flat with a spherical annular periphery 17b to engage the valve seat 18<a> The valve member 17 is operated by a fingerknob adjustably attached to a flexible connector 26 fixed to a slidable rod 27 carrying an arm 29 slotted at its upper end 30 to engage a pin 31 on the valve member 17. Specification 12056/15, [Class 135], is referred to.
