发明名称 Six ball pool rack
摘要 A six ball pool rack is constructed having a frame defining two separate compartments. Each compartment is generally kidney-shaped and holds three pool balls in tangential relationship on a pool table. The compartments are joined by a center portion of the frame which separates the two groups of three balls and has indicator indicia imprinted thereon. The three balls are arranged in each compartment such that one of the balls is in contact with the center portions of the frame which separates the compartments.
