Abstract

974,301. Inflating valves. METTOY CO. Ltd. March 29, 1961 [April 1, 1960], No. 11566/60. Heading F2V. [Also in Divisions A6 and B5] A valve 12 used, e.g., in an inflatable ball (see Division A6), comprises a rigid stem 13 having a passage 14, 15 for an inflation tool T screwed in thread 16 and a passage 17 with an aperture 18 at its inner end. This aperture extends to a groove 19 which has a rubber tube 21 expanded on it to prevent the escape of air from the ball. It may be slightly shorter than the groove 19 to prevent buckling. The air passes through aperture 18 expands tube 21 and enters the ball through an air-inlet slit 22. A modified valve (Fig. 5) has the rigid polyvinyl chloride stem 13a which is elongated to 29 and has an outlet 30 at a point centrally of a rubber-like tube 31. Other modifications are a valve (Fig. 7) with a straight inflation passage 36 surrounded by a curved stem 37, 38, 39 and one (Fig. 11) comprising a length of extended polyvinyl chloride split tubing 49 with the elastic tubing 50 expanded on it, mounted on the pin 52, the gap in tubing 49 above and below the aperture 58 being filled with the moulding material when the ball is moulded.
