ABSTRACT:
A return coin discharge unit mountable in the box cabinet of a coin operable telephone apparatus has an entry opening into which return coins from the apparatus will drop and it includes a ramp in a passage down which ramp the dropped coins will slide and issue through a horizontal slot at a front end of the unit. An open ended trough having a curved inner bottom surface located on the ramp below the entry opening serves to cause dropped coins moving over its curved surface to obtain horizontal positions for sliding down the ramp. And, a flap gate pivoted in the passage and inclined forwardly with its bottom edge resting upon the ramp functions to allow one coin at a time to pass beneath it to the exit slot. Explosives and blocking material are prevented by the narrow horizontal slot against entry into the unit; and the gate curbs the extent to which damaging wires may be inserted through the slot into the unit.
