7324. Prosser, A. E. March 23. Drawings to Specification. Balls.-A ball for playing the game of rackets, tennis, or fives consists of the usual core of tightly-wound cloth or thread moulded under pressure, but is provided with an adhesive damp - proof cover of linen, such as surgical binding. The cover is preferably formed from a single star-shaped blank,' and, owing to the adhesion of the cover to the core, stitching of the meeting edges of the cover is unnecessary.
