  • Chute for controlling the motion of a token moving by gravity through a token-receiving device
    Patent number: 5139128
    Abstract: A token receiving chute for use in a token operated device is disclosed. The chute is designed so that a token inserted therein will fall toward an appropriate location due to the force of gravity. In order to decrease the kinetic energy imparted to the falling token, and thereby increase the accuracy of various coin sensing devices to be subsequently employed, an inclined wall section is provided for imparting lateral momentum to the falling token causing it to bounce back and forth between the side walls.
