Abstract
Apparatus to prevent the theft of coins in the coin return channel of pay phones and coin vending machines. Three vanes are pivotally mounted within or adjacent the return channel to provide a bypass path for returned coins so that blocking of the coin return door or the use of a wire attached to a coin for inserting a wad of material will not prevent retrieval by a user of the telephone or vending machine.
Claims2
In a coin operated telephone having a coin retrieval receptacle, a coin return channel for discharging the coin into said coin retrieval receptacle, and a coin return door pivoted at its upper end for swing movement inwardly toward the coin discharge end of said coin return channel for providing finger access to the coin retrieval receptacle for the removal of said coin, the improvement comprising a pair of first and second vane means each pivotally mounted between said coin return channel and said coin retrieval receptacle each having a normal position permitting said coin to pass between said vane means from said coin return channel into said coin retrieval receptacle, said vane means each assuming an alternate position in response to the insertion of a foreign body to block said coin return channel, the alternate positions of said vane means forming a wall between said coin return channel and said coin retrieval receptacle and providing a bypass path for said coin to pass into said coin retrieval receptacle thereby defeating the effort to prevent the normal return of said coin.
