ABSTRACT Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals. The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid. An entry slot in an entrance blocker, which is an integral part of the lid, is in substantial alignment with the coin insert slot of the front panel of the machine in normal operation. The lid is connected to a torsion spring and is associated with a coin reject lever. The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine. In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing. Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring. This moves the coin entry slot and the blocker slot out of substantial alignment, preventing the insertion of additional foreign matter or another coin. Removal of the foreign matter allows the lid to return to its normal operating position under the force of the spring.
