Abstract
Conversion mechanism is disclosed for converting a coin-operated dispensing apparatus including an actuating means and a coin-receiving wheel coupled thereto for movement thereof in response to receipt of a single coin, to a mode of operation only in response to receipt of two coins. The conversion mechanism includes a drive plate coupled to the coin-receiving wheel for rotation therewith and carrying a pivotable drive pawl normally biased toward driving engagement with a modified actuating member, and a cam member for moving the pawl out of driving engagement with the actuating member upon rotation of the coin-receiving wheel in response to a first coin, the pawl moving back into driving engagement with the actuating member upon rotation of the coin-receiving wheel in response to insertion of a second coin.
Claims15
Coin controlled apparatus comprising coin-enabled means operative upon receipt of a coin therein for undergoing a predetermined movement, actuating means movable for actuating an associated device, and clutch mechanism coupled to said coin-enabled means and movable between an engaged condition coupling said actuating means to said coin-enabled means for movement therewith and a disengaged condition decoupling said actuating means from said coin-enabled means, operation of said coin-enabled means upon receipt of a first coin therein effecting movement of said clutch mechanism to the disengaged condition thereof so that said actuating means is not moved with said coin-enabled means, further operation of said coin-enabled means upon receipt of a second coin therein effecting movement of said clutch mechanism to the engaged condition thereof for moving said actuating means with said coin-enabled means to perform said predetermined function, whereby said predetermined function is performed only after two coins are received in said apparatus.
In a coin-controlled dispensing mechanism having a dispensing member for dispensing merchandise only upon insertion of two coins, the combination comprising a housing having a coin-receiving slot therein, a coin-receiving wheel mounted for rotation on said housing, a handle connected to said coin-receiving wheel for effecting rotation thereof, means for preventing rotation of said coin-receiving wheel in the absence of a coin therein, an actuating member mounted on said housing and movable for engagement with and actuation of the associated dispensing member, drive means coupled to said coin-receiving wheel for rotation therewith and disposed for driving engagement with said actuating member, bias means urging said drive means toward driving engagement with said actuating member, and a cam member disposed in the path of said drive means for camming engagement therewith to move said drive means out of driving engagement with said actuating member, rotation of said coin-receiving wheel upon receipt of a first coin therein effecting movement of said drive means into camming engagement with said cam member to move said drive means out of driving engagement with said actuating member so that said actuating member is not driven in response to rotation of said coin-receiving wheel, further rotation of said coin-receiving wheel upon receipt of a second coin therein effecting movement of said drive means into driving engagement with said actuating member for driving thereof by said coin-receiving wheel into engagement with the associated dispensing member for actuating same, whereby actuation of the associated dispensing member is effected only upon the receipt of two coins in the coin-receiving wheel.
In a coin-controlled dispensing mechanism having a dispensing member for dispensing merchandise only upon insertion of two coins, the combination comprising a housing having a coin-receiving slot therein, a coin-receiving wheel having two diametrically spaced-apart coin receptacles and mounted on said housing for rotation through a half-revolution upon receipt of a coin therein, a handle connected to said coin-receiving wheel for effecting rotation thereof, means for preventing rotation of said coin-receiving wheel in the absence of a coin in one of said receptacles, an actuating member mounted on said housing for engagement with and actuation of the associated dispensing member and having two equiangularly spaced-apart drive surfaces thereon, drive means coupled to said coin-receiving wheel for rotation therewith and disposed for engagement with said drive surfaces of said actuating member, bias means urging said drive means toward engagement with said drive surfaces of said actuating member, a cam member disposed in the path of said drive means for camming engagement therewith to move said drive means out of engagement with the drive surfaces of said actuating member, rotation of said coin-receiving wheel through a first portion of a first half-revolution upon receipt of a first coin in one of said receptacles effecting movement of said drive means into camming engagement with said cam member to move said drive means out of engagement with one of the drive surfaces of said actuating member so that said actuating member is not driven during movement of said coin-receiving wheel through the remainder of its first half-revolution, rotation of said coin-receiving wheel through a first portion of a second half-revolution upon receipt of a second coin in the other of said receptacles effecting movement of said drive means into engagement with the other drive surface of said actuating member to effect rotation thereof with said coin-receiving wheel through the remainder of the second half-revolution to actuate the associated dispensing member, whereby actuation of the associated dispensing member is effected only upon insertion of two coins in the coin-receiving wheel.
In a dispensing apparatus having a dispensing member and actuating means for the dispensing member and a coin-receiving wheel rotatable upon receipt of a single coin therein to move the actuating means into engagement with the dispensing member for actuation of same, conversion mechanism comprising an actuating member adapted to be substituted for the actuating means and disposed for engagement with and actuation of the associated dispensing member, drive means coupled to said coin-receiving wheel for rotation therewith and disposed for driving engagement with said actuating member, bias means urging said drive means toward driving engagement with said actuating member, and a cam member disposed in the path of said drive means for camming engagement therewith to move said drive means out of driving engagement with said actuating member, rotation of said coin-receiving wheel upon receipt of a first coin therein effecting movement of said drive means into camming engagement with said cam member to move said drive means out of driving engagement with said actuating member so that said actuating member is not driven in response to rotation of said coin-receiving wheel, further rotation of said coin-receiving wheel upon receipt of a second coin therein effecting movement of said drive means into driving engagement with said actuating member for driving thereof by said coin-receiving wheel into engagement with the associated dispensing member for actuating same, whereby said dispensing apparatus is converted to a mode of operation wherein actuation of the associated dispensing member is effected only upon the receipt of two coins in the coin-receiving wheel.
