Balls. - An inflating plug for balls, bladders, and other inflatable rubber bodies comprises an outer portion A composed of vulcanized rubber and an inner portion B of less highly vulcanized or unvulcanized rubber, both portions being of substantial thickness. The plug is formed by omitting the accelerator from, and reducing the proportion of accelerator in, the inner portion B. The position of the plug is indicated by a projection E, such a.s is described in Specification 328,047.
