Abstract
A device for dissipating the kinetic energy that causes bouncing which might otherwise effect the results of the coin tests in coin handling apparatus. The device consists of a piece of very hard material such as sintered aluminum oxide which is mounted on the frame of the mechanism and is arranged to be struck by coins travelling along a path through the coin handling mechanism.
Claims15
A coin handling mechanism including means defining a coin path through the mechanism, the means including at least one energy dissipating device arranged to be struck by a coin travelling along the path and cause a change in direction of the path, the energy dissipating device comprising a rigidly mounted solid piece of material having a hardness value greater than 9 on the Mohs scale.
A coin handling mechanism for identifying acceptable coins of one or more predetermined denominations including means defining a coin path through the mechanism, the means including at least one energy dissipating device arranged to be struck by a coin travelling along the path and cause a change in direction of the path, the energy dissipating device comprising a rigidly mounted piece of ceramic material having a hardness sufficiently greater than that of any coins of the predetermined denominations that the coin has substantially no bounce when it strikes the energy dissipating device.
