ABSTRACT:
A coin mechanism for a vending machine comprises a cylinder rotatable in a passageway within a housing to release vended product to a purchaser. Operation of the mechanism requires insertion of purchase coins into coin slots accessible when the cylinder partially protrudes from the housing. The cylinder is thereafter substantially completely inserted into the housing and rotated by means of a handle located on one end thereof. Upon rotation of the cylinder, the coins prevent engagement of locking pawls mounted in the housing with either of two separate mechanism-blocking shoulders located on the cylinder. The end of the cylinder opposite the handle is connected to a coupler member, which in turn is fastened to a spiral product coil, rotation of the cylinder causing rotation of the coil and the release of product therefrom. The coupler member also includes a ratchet wheel which cooperates with a pawl in the housing to prevent improper rotation of the cylinder. Changes in the number and kind of coins required to operate the mechanism can be effected by adjusting the degree of cylinder travel into the housing, and by the insertion of coin-altering plugs inserted in the cylinder's coin slots.
