Abstract

200,923. Doulton, H. L., Corby, S. F., and Pleace, R. J. April 21, 1922. Piston valves; materials, special. - The cover a of a valve is screw threaded to receive the spindle c which carries at its lower end a cup d of woodite or the like, controlling the flow through openings j. When the valve is raised above the perforations, liquid is prevented from passing along the spindle, so that a stuffing box may be eliminated. Specification 10460/03 is referred to.
