Abstract: 747,740. Coin-freed apparatus. ROWE MANUFACTURING CO., Inc. July 17, 1953, No. 19833/53. Class 27 Coin-freeing mechanism for vending apparatus comprises coin shoots A, B and C for coins of different denominations and pairs of brushes 182 extending into the shoots and bridged by coins supported in the shoots by a rotatable coin shelf 204 to energize the circuits of relays 16, 24 and 32, the relays 16 and 24 controlling change-giving solenoids 22 and 30 and the relay 32 controlling a motor 38 for initiating the vending cycle; each relay controls a pair of armatures, one, such as 20, completing the main operating circuit and the other, such as 18, completing a holding circuit that maintains the relays energized after the coins have been accepted and until a normally-closed switch 84 is opened by a cam operated by the motor 38 at the end of the vending cycle. The coin shoots are formed between a fixed panel 152 and a movable panel 150 carrying the brushes, sufficient brushes being provided in each shoot for operation by five, ten and twenty-five cent coins to obtain goods up to the value of twenty-five or thirty cents; the mechanism is adapted to either ten, fifteen, twenty, twenty-five or thirty cent purchases by fitting one of five interchangeable wiring panels 52. Figs. 1 and 6 show the wiring panel for fifteen cent purchases, in which two pairs of brushes in the ten cent shoot A, three pairs in the five cent shoot B and one pair in the twenty-five cent shoot C, are connected to the relays'and the change-givers 22 and 30 are loaded to give ten cents and five cents change, respectively. Three five cent coins in the shoot B will make the connections 114-116, 110-112 and 106-108 or one ten-cent coin in the shoot A and one five-cent coin in the shoot B will make the connections 94-96 and 106-108 so that the relay 32 only is operated and the vending cycle is begun without the change-givers being energized. However, two ten-cent coins in the shoot A will make the connections 98-100 and 94-96 so that the relay 32 is energized through the relay 24, thus operating the change-giver 30 to return five cents change and similarly a twentyfive cent coin in the shoot C will make the connections 130-132 so that the relay 32 is energized through the relay 16, thus operating the change-giver 22 to return ten cents change. Other wiring panels operate similarly with only the changegiver 30 loaded to give appropriate change, when required by the coin or aggregate coins used. For example, the twenty-five cent panel, Fig. 3, with five five-cent contacts and three ten-cent contacts, operates through the relay 32 without change-giving for five five-cent coins, two ten-cent coins and one five-cent coin (through conductor 141), one ten-cent coin and three five-cent coins (through conductor 142) and one twenty-five cent coin or, if three ten-cent coins are inserted, the relay 32 is operated through the relay 24 so that five cents change is returned. A push-button switch 46 may be fitted for initiating the vending cycle and may be controlled by individual selector buttons in a multicolumn vending apparatus. The inserted coins pass through a slug rejector and correct coins pass through apertures in a member 174 to the coin shoots while rejected coins are diverted by a baffle 178 to a coin return shoot. While passing down the shoots, the coins press back a wiper 192 but if more coins than the number of pairs of brushes in a particular shoot are inserted, the uppermost excess coin of the pile held in the shoot is tilted by the wiper to'fall through a hole 214 into the coin return chute. During the vending cycle, the shelf 204, which supports the coins on its insulated top 202, is rotated counterclockwise, as shown in Fig. 6, to release the coins and divert them forward into a coin box. The shelf may be rotated clockwise by a coin-return member 234 acting on a bracket 232 to return the coins to the user but, once the vending cycle has started, a relay 40 in the motor circuit locks this member by the insertion of a pin 77 in a hole 234. The relay 40 also operates a change-giver which, if it is required to reduce the vending price by one, two, three or four cents, is appropriately loaded to return that number of one-cent coins at each purchase. Clearing-apparatus.-When the coin shelf 204 is rotated counterclockwise to collect the coins, it operates a two-armed lever 222 (not shown) to move the brush panel 150 outwards to open the coin shoots and clear them; when rotated clockwise to return the coins, the shelf bears directly on the brush panel to open it.
