Abstract
An anti-stuffing device involves removing the floor at the end of the coin return chute to create a floor opening, placing a wall over the end of the chute to stop coins coming down the chute, pivotally mounting at the bottom end of the wall a compound lever so that its one leg closes-off the floor opening when in a first position towards which it is biased, and attaching one end of a compression spring to the other leg of the compound lever and its other end to the bottom of the pivoted door normally closing-off the front opening to the coin return bucket. The spring is of such length that when the bucket door is closing-off the front opening, it yieldably urges the compound lever to its first position closing-off the floor opening and when the lower end of the bucket door is pushed inward it pushes the compound lever so that its one leg moves away from the floor opening and allows the pay telephone user's coins for uncompleted calls to be retrieved by him. Methods defeat old and new stuffing techniques.
