Pool ball
First Claim
1. A pool ball comprising, in combination:
- (a) a cylindrical object having identical numeral designations on its opposite ends;
(b) a colored disc member surrounding in continuous engagement the complete cylindrical surface of said object resulting in a disc-shaped assembly with said numeral designations on opposite sides of said disc-shaped assembly; and
,(c) a solid transparent hemispherical member comprised of polyester resin having a uniform imperforate surface completely covering the numeral designation on each of said opposite ends of said cylindrical object and each of the opposite sides of said disc member thereby forming a sphere with said disc-shaped assembly, the geometric center of said sphere coinciding with the center of gravity of said disc-shaped assembly, and the transparency of said hemispherical members rendering visible said colored disc member and said numeral designations.

Abstract
A transparent game ball particularly useful as a billiard or pool ball is disclosed, along with manufacturing processes and apparatus for producing the ball. The ball includes a weighted opaque object centered within the transparent spherical outer covering of the ball for providing the required weight for the ball as well as a desirable appearance. The transparent portion of the ball is produced bubble free of polyester resin through the use of a special, two-piece mold for forming the entire ball at one time. Into this two-piece mold a centering spider or disk of the same rigid polyester resin is inserted. The spider or disk may be either transparent or opaque, and is used to precisely center the opaque weighted object at the ball'"'"'s geometric center.
