Abstract

416,417. Pressure gauges. JABLONSKY, B., 19, Belsize Crescent, Hampstead, London. March 7, 1933, No. 6895. [Class 106 (ii).] A press-on connector for use in inflating pneumatic tyres comprises a double valve g adapted to be unseated when the connector is pressed-on and thereby connect the compressedair supply tube b with the tyre valve and also with a chamber v leading to a spring-loaded escape valve l which opens when a predetermined pressure is exceeded. The loading of the spring n for the valve b is adjusted by rotating a cam o, the pressure being indicated by a pointer r. The outlet passage for the escaping air is obstructed by the sharp edge of a rim u on the valve seat k so as to produce a whistling sound. A ball valve may be used instead of the needle valve l.
