Abstract
A bumper mechanism is disclosed which is adapted to be mounted in a pin ball machine having a playing surface along which pin balls can be projected. The bumper mechanism comprises first and second bumper elements which define a slot therebetween for receiving pin balls projected on the play surface. One of the bumper elements is mounted for sliding movement between a first position adjacent the other of the bumper elements and a second position remote from the other of the bumper elements, in response to entrance of a pin ball into the slot. Downward movement of the bumper element causes it to engage a drive element rotatably mounted in the pin ball machine so that cooperating means on the drive element and the depressed bumper element engage each other and drive the depressed bumper element back towards its first position adjacent the other bumper element in response to rotation of the drive element. In this manner the pin ball which entered the slot between the bumper elements is squeezed by the bumper elements and projected from the bumper mechanism.
