Abstract

922,788. Venting moulds. DUNLOP RUBBER CO. Ltd. Aug. 20, 1959 [Aug. 25, 1958], No. 28444/59. Class 21, [Also in Groups V and XXIX]. A vent peg 15 that is axially and radially displaceable in a mould member 1, comprises a shaft 5 carrying a valve disc 6 at one end and a projection 7 at its other end, the projection 7 serving to retain the valve disc 6 in a countersunk aperture 2 forming a seating surface 4 against which the disc 6 is pressed in an air-tight manner when acted on by the material in the mould, the radial clearance between the shaft 5 and the bore 3 during this sealing period being greater than the radial clearance between the disc 6 and the aperture 2 so that when the vent peg is not acted on by the material in the mould its shaft 5 is inclined with respect to the bore 3 to permit venting to take place.
