Abstract

713,699. Sluice valves. CRANE CO. April 3, 1952, No. 8564/52. Class 135 In a gate valve having a closure member consisting of halves 11, 12 with mating, inclined, plane surfaces 13, 14 and 15, 16 to provide a wedging action, the said inclined surfaces are formed on raised, annular portions so that they may be machined individually in a lathe. The closure half 11 is connected to a screwed actuating stem 18, whilst the other half 12 "floats" but is connected to the half 11 by links 43, 44. Spring-pressed guide plates 24, 25 engage the halves of the closure member.
