ABSTRACT:
The proper inflation of playground balls is controlled by fixing a strap to a predetermined circumference equal to the circumference of the ball at proper inflation. The strap is then placed around the center of the ball and the ball inflated until the strap is tight. The strap is then removed and the ball is properly inflated. The strap may be secured at any of a plurality of settings equal to the circumference at proper inflation of any of a plurality of different balls. The strap is marked with numbers equal to the diameter at proper inflation of the ball to be inflated. The desired circumference of the strap is preferably maintained with a hook-and-pile type fastener.
