Abstract

486,385. Plug cocks. GERDTS, G. F. Oct. 6, 1937, No. 27089. Convention date, Dec. 7, 1936. [Class 135] [Also in Group XXXIV] In a plug cock a limited relative movement is provided between the handle d and the plug b which movement is transmitted through a pawl and ratchet mechanism k to rotate a screw plug n located in a chamber o and thus force lubricant therefrom to the working surfaces of the cock and to the space s below the plug. The relative play is provided by a pin f on the plug cooperating with a slot h in the handle d, and the movement is ensured by a pin e on the plug casing engaging a notch in the plug, the pin being engaged by a lug g during the period of relative movement. The pawl k can slide on its pivot pin l to render the lubricating device inoperative under excessive pressure. The screw plug n may have a head i for hand operation.
