Abstract

503,963. Plug cocks. NORTHERN AIRCRAFT & ENGINEERING PRODUCTS, Ltd., and BRACE, R. E. Oct. 20, 1937, No. 28548. [Class 135] In a plug cock the conical plug member b is provided at its smaller end with an actuating stem and is pressed onto its seat by a spring g acting against its larger end through a round-headed pin f, the head of which enters a rounded recess in the end face of the plug. The spring g is located within a bush k. The plug may be freed from binding by axial movement against the spring.
