ATTORNEY COIN COUNTER A large percentage of coin counters available commercially today are basically mechanically operated and use complicated mechanical mechanisms to perform the required job. These counters are subject to numerous breakdowns requiring a considerable amount of service which results in high operating expense as well as lost machine time.

It is therefore an object of this invention to provide a novel coin counter which is simple in construction and reliable in operation.

Another object of the invention is to provide a coin counter which is electrically controlled to provide positive accurate control of the coin count. Other objects and advantages of the invention will become readily apparent as the specification proceeds to describe the invention with reference to the accompanying drawings, in which:

FIG. I is a schematic representation of the new and novel coin counter;

FIG. 2 is a top view of coin-actuated star wheel;

FIGS} 3 and 4 represent two forms of the coin selector cams; and

FIG. 5 is a schematic circuit diagram of the new and novel coin counter. Looking now to FIG. 1, the overall novel coin counter is shown schematically. Coins to be packaged in rolls are supplied from a coin collection container to the transfer tube 12 by a'suitable transfer roll 14 driven by motor 16 through power transmission belts l8 and 20 and clutch 22. Transfer roll 14 is of a fairly soft resilient material and has an outer surface of frictional material to firmly grip the top of each coin as it is delivered from the coin collection container 10 through the deflector members 24 and 26 to the transfer roll 14. The driven transfer roll 14 frictionally engages the top of each coin 28 (FIG. 2) and moves it forward against the star wheel 30 during its path of travel onto the chute 32 and into the transfer tube 12. Located at the bottom of the transfer tube 12 is a pair of pivotally mounted pallet members 34 to retain coins 28 in the transfer tube until a certain predetermined number have been collected in the transfer tube 12. When this predetermined number of coins 28 have been collected inthe transfer tube, the pallet members 34 are pivoted away from each other to allow the coins to drop into the collection tube 36 from whence they are wrapped in any suitable manner. Connected to the star wheel 30 is an elongated shaft 38 to which is rigidly attached and rotating therewith a worm 40 and a star wheel cam 42. The worm 40 engages and drives a worm gear 44 mounted on a shaft 46 to which is mounted count cams 48 and 50. Each count cam 48 and 50 has a plurality of cam surface actuators 52 which engage periodically the switches 54 and 56, respectively, for reasons hereinafter explained. Count cam 48 has four cam surfaces 52 to allow four counts of fifty coins for each complete rotation of the worm gear 44 while count cam 50 has five cam surfaces 52 to allow five counts of 40 coins for each complete rotation of the worm gear 44. The star wheel 30, worm 40 and worm gear 44 are suitably selected to provide the count indicated by the action of count cams 48 and 50.

OPERATION Looking now to the drawings in more detail, especially FIG. 5, the operation of the coin counter will be explained. As explained before, the cams 48'and 50 can be selected to count out either 50 or 40 coins. In FIG. 5, the selector switch 58 is in the position to select a count of 40 coins, thereby placing the cam 50 in operative relation to the switch 56.

Assume now for the sake of discussion, that the counter is in the process of counting and coins are being supplied to the transfer tube 12. When the thirty-sixth or thirty-seventh coin passes through the star wheel 30, coin count cam surface 52 of cam 50 actuates switch 56 to energize solenoid 59 through relay.60. Energization of solenoid 59 causes solenoid plunger 62 (FIG. 1) to pivot star wheel switch support 64 clockwise to place the star wheel switch 66 into the path of travel of star wheel cam 42. Then when the fortieth coin passes through the star wheel 30, the star wheel cam is rotated into a position where it engages the star wheel switch to actuate the relay coil 68 to open the relay switch 70. Opening of the relay switch 70 deenergizes the clutch 22 to break the power train from the motor 16 to the coin transfer roll 14 thusly stopping the supply of coins to the transfer tube 12. To prevent the star wheel cam 42 from overriding, a mechanical stop member 72 is provided to prevent further rotation of the cam 42 and the star wheel 30 connected thereto through shaft 38.

Opening of relay switch 70 also breaks the circuit to relay coil 74, which, after the charge on the capacitor 76 has been dissipated, opens relay switch 78 and closes relay switch 80. Relay switch 78 is in the circuit with the coin-wrapping machine (not shown) and causes the machine to either start another cycle or continue its cycle if the cycle is not complete. Relay switch 80 is in the circuit which controls the opening of the pallet members and either causes the pallet members to open to drop the coins into the coin-wrapping machine if the cycle is complete or presets the pallet member circuit so that the pallet members will be opened when the coin-wrapping machine is ready to receive the stack of counted coins.

Then when a new cycle is started the pallet members 34 close and pallet switch 82 is actuated momentarily to pulse relay coil 84 which closes relay switch 86 and in turn maintains relay coil 84 energized through switch 56. At the same time switch 60 is opened to deenergize solenoid 59.

Deenergization of solenoid 59 causes star wheel switch support 64 to pivot counterclockwise away from the star wheel cam 42 allowing star wheel switch 66 to open to deenergize the relay coil 68. Deenergizing of relay coil 68 closes relay switch 70 to energize the clutch 22 to start the coin transfer roll 14 again on the next cycle. After a few coins have rotated the star wheel 30, the cam surface 52 of the cam 50 will move off of switch 56 to deenergize relay coil 84 which closes relay switch 60 and opens relay switch 86 to set up the circuit once again for the next count.

It can readily be seen that the herein disclosed novel coin counter provides a method of accurately counting and supplying a predetermined number of coins with a minimum of mechanical motions. Further the disclosed apparatus is simple in design and will provide much longer service life than the counters presently being employed commercially.
