  • Patent number: 4437557
    Abstract: In a coin collector of a vending machine including a credit indicator, a swivel plate obstructs, in its rest position a coin return channel. The plate is pivotable in one direction out of its rest position by the stroke of a coin return bolt and is operatively connected to the credit indicator for resetting the same. To ensure that upon actuation of the coin return bolt, the credit indicator is reliably reset, the plate keeps blocking the coin return channel during a first partial stroke of the coin return bolt, and resets the credit indicator. During a subsequent second partial stroke, the plate swivels into the coin return channel.

  • Patent number: 4323147
    Abstract: A coin operated dispensing arrangement in which a plurality of counting cams can be set to reflect the selling price of items to be dispensed. These cams are rotated in response to the insertion of coins into the device, and a blocking rod is movable from a normal blocking position to a release position which permits dispensing of selected items in response to the insertion of coins having a value corresponding to the selected selling price. A plurality of movable sensing members cooperate with the cams, and a slide member holds normally the blocking rod in the blocking position, while being movable to a disengaging position by any one of the sensing members. A plurality of control levers are pivotable in front of the slide member into and out of the path of movement of respective sensing members.
