ABSTRACT:
A mechanism prevents explosion damage to coin pay telephones by providing an almost horizontal offset in the coin path so that a wad of paper cannot be moved by the weight of subsequently inserted coins. For existing phones, a retrofit provides a horizontal offset by locating a horizontal slot to one side of the existing coin chute entrance and having in back of it a relatively horizontal slippery surface for sliding the coin sideways and then downwards into a tunnel in alignment with the existing coin chute. The tunnel has a sloping bottom surface so that the coin rolls therein under the force of gravity into the existing coin chute. In another embodiment, the horizontal slot is further arranged perpendicular to the existing slot and the relatively horizontal slippery surface slides the coin back towards the horizontal slot and then downwards into the tunnel with a bottom sloping surface operative to roll the coin into the existing coin chute. The mechanism may also be integrally incorporated in the design of new telephones.
