Abstract

341,550. Tennis balls and other inflatable rubber bodies. WILLIAMS, L. E., 82, Farringdon Street, London, and JAMES, G. E., Norfolk Works, Upper Bristol Road, Bath. Oct. 19, 1929, No. 31839. [Class 132 (ii).] An inflating plug for tennis balls, bladders, and like inflatable rubber bodies comprises outer and inner layers A, C of vulcanized rubber and an intermediate layer B of unvulcanized or less highly vulcanized rubber or its equivalent to form a selfsealing medium. Additional layers may be employed if desired. A sleeve D of rubber, which becomes comparatively highly vulcanized when the ball is vulcanized, encloses some or all of the layers. A projection F protruding into the outer cover indicates the position of the plug. Specification 328,080, [Class 132 (ii), Games], is referred to.
