Abstract

185,908. Old, R. G., and Hill, F. W. July 16, 1921. Tyre and like inflating and deflating valves.-- A tyre valve is provided with an inner tubular stem fitted with a valve head and carrying a non- return valve, so that a positive closure of the air passage may be obtained by screwing down the sleeve after inflation. The outer tube a, Fig. 1, is provided with a screwed sleeve b having a collar c by which an airtight joint is obtained against a washer d. A tubular stem e is adapted to slide within the sleeve b, rotation being prevented by a stud h engaging in a groove i. The stem is operated by a nut f which is prevented from moving axially by a collar g rotatably mounted in a recess in the sleeve c. The inner end of the stem e is recessed to receive a non- return rubber valve k, and carries a plug o having a valve disc to close the air passage p. When the tyre is to be inflated, the stem e is raised until the collar l forms an airtight joint with the washer m, and the air passage p is opened. After inflation, the stem e is forced downwards to close the air passage p. In a modification, the valve o may be a conical rubber plug and the valve k of metal. In another modification, Fig. 4, the stem e is rotatable and is operated by a member f, while the valve o is rotatable relatively to the sleeve.
