Title:
BALL THROWING MACHINE
Document Type and Number:
Japanese Patent JPS5397531
Kind Code:
A
Abstract:
A ball projecting device is provided for propelling a ball pneumatically, wherein the speed of the ball projected is, at least in part, determined by utilizing a pneumatically operated, preferably variable, detent in the barrel of the device. The detent holds the ball within the barrel until a predetermined air pressure is built up behind the ball, which then causes the detent to quickly, almost immediately, collapse, permitting the ball to be projected out of the barrel.
