Abstract

541,842. Pipe couplings. BROOM & WADE, Ltd., and ELWESS, E. June 8, 1940, No. 10040. [Classes 99 (i) and 99 (ii)] [Also in Group XXIX] In a coupling used when re-charging compressed air bottles and the like each coupling half 6, 26, has a valve 7, 28 respectively. The half 6 is attached to the air reservoir and the half 26 to the charging means. The valve 7 which has a guiding stem 14 is normally held closed against its seating 17 by the air pressure and, if desired, by a light spring. A projection 19 through which a bore 18 extends protrudes from the coupling half 6. The coupling half 26, which may be formed of two parts screwed together, has a stepped bore containing a spring-pressed valve member 28 and an internal flange 30 forming a valve seat. Between the flange 30 and another flange 36 is a hat leather 38 and distance piece 39. The valve 28 has a projecting stem 34, 35, so that when the coupling halves are joined the stem 34, 35 abuts the projection 19 so as to open the valve 28 whereupon the pressure of the air supply opens the valve 7 in the other coupling half 6. A cap may be fitted over the coupling half 6 when the coupling parts are disconnected from one another.
