Abstract

127,491. Bliss, J. Nov. 5, 1918. Lift valves; handles and keys.-To prevent tampering with keyoperated rotatable parts, such as screw-down and other valves and cocks, the latches of cupboards, &c., the rotatable part A is provided with a concentric circular recess B at the bottom of which a smaller eccentric recess B, preferably circular, is formed. A key C for turning this part comprises a circular part D and an eccentric extension D<1> which correspond in shape and size with the recesses in the rotatable part.
