Abstract
323,969. Jones, A. E. R. March 12, 1929. Closure members, wedging or jamming.-In a rotary plug cock or valve, having a screwed spindle shank adapted to cause a lift of the plug with rotation, the screwed shank h of the plug screws into a cap member h<1>, which is secured to the cock casing a by screwed engagement with a loose collar b itself screwed to the casing a. The parts are secured by grub screws e<1>. A Stauffer grease box b<1>, with non-return valve c<1> supplies lubricant to grooves p in the plug; a stop pin k limits the movements of the plug and prevents exposure of the grooves p to the liquid flow passages a'. Specifications 285,297 and 286,077 are referred to.
