ABSTRACT:
A coin selecting funnel for use in a coin-operated vending machine, for receiving coins inserted into the machine through a slot, for routing coins larger than a certain diameter into a descending a coin chute, and for routing coins smaller than that certain diameter into a coin return passage includes a trough having a wall and a ledge which interest along a vertex oriented so that inserted coins are conducted downwardly from a coin slot to a coin chute, the coins passing along the wall with their faces flush to the wall and their edges supported by the ledge. The wall contains an aperture having an upper edge extending parallel to the vertex of said trough and spaced from the vertex by a distance exceeding that certain diameter. The aperture also includes a lower edge extending parallel to the vertex and spaced from the vertex by a distance less than half that certain diameter. As inserted coins pass along the wall, coins smaller than that certain diameter will topple over the edge of the aperture into a coin return passage and coins larger than that certain diameter will be supported by the upper and lower edges of the aperture so as to be conducted along the trough to the coin chute.
