Abstract
A wheel for a ball throwing machine includes a tire-mounting wheel formed of two lateral halves of spun metal each having a central portion and an angularly extending rim portion, the central portions of the two halves being arranged in abutting relation with the rim portions diverging outwardly. A resilient solid polyurethane tire is molded integrally to the outer surfaces of the diverging rim portions, securing the two halves together. The tire is molded to a resilient hardness ranging between about 25A and 75A Durometer, preferably about 40A Durometer. Circumferentially spaced registering holes in the central portions of the two wheel halves removably receive bolts by which to secure the wheel to the hub of a power driven rotary shaft of a ball throwing machine.
