Abstract

411,917. Playing balls. WEBBER, F. G., 19, Station Road, Norwood Junction, London. Dec. 16, 1932, No. 35774. [Class 132 (ii).] In a football, netball, punchball, water-polo ball, or the like, the inflatable bladder h is inserted in the usual lacing aperture d, and attached to a leather or other flap a, stitched to the outer casing b at b <1>, by forcing the flange g<1> of an inflator valve g, formed integral with the bladder, through a hole a<1> in the flap. The flap may be radially slotted from the hole a<1> to facilitate this operation. The outer casing is apertured at e for the insertion of an inflator nozzle or deflating tool, and after inflation, an elastic plug f is forced through the hole e into the valve stem, being retained in position by its flange f <1>.
