Abstract
An improved billiard ball is provided comprising a major portion and a minor portion together forming a solid, spherical body. The minor portion is preformed with inclined surfaces which define an interlock adapted to cooperate with associated surfaces of the major portion to form a mechanical bond between the major and minor portions after the major portion is formed about the minor portion. When the minor portion is molded in the shape of a bracelet, a slit may be provided therein to relieve stresses caused by shrinkage during cooling.
Claims5
A billiard ball comprising:
- a major portion formed of a thermosetting plastic and a minor portion of thermosetting plastic together forming a solid spherical body;
- said minor portion comprising a bracelet having surfaces thereon defining a mechanical interlock adapted to cooperate with associated surfaces of said major portion in forming a mechanical bond between said major and minor portions, said bracelet having an outer surface, a substantially flat inner surface, a pair of opposed circular openings extending through the bracelet perpendicular to the bracelet axis, each of said openings extending on opposite sides of a diameter of said ball from said inner surface toward said outer surface to a first position and then flaring out at a taper from said first position to said outer surface, a pair of sides connecting said inner and outer surfaces, a pair of recesses intermediate said inner and outer surfaces formed by a pair of diametrically opposed surfaces extending toward each other from said sides, and said interlock comprises two surfaces extending between said opposed surfaces and said flat surface inclined toward each other and converging away from the center of the ball.
