Coin dispensing mechanism

Claim 2

Coin dispensing apparatus including first and second plates supported for rotation in stacked overlapping relation, power means for rotating said plates in opposite angular direction about parallel axes normal to the plane of each plate, a plurality of coin receiving apertures formed in each of said plates with the apertures in each plate arranged equidistant from the respective axis of rotation of the plate, the circles formed by a line joining the aperture centers in said plates being tangential, whereby successive apertures in said plates move into registration as the plates rotate to permit a coin in one of the apertures of said first plate to move into one of the apertures of said second plate with each registration of said plate apertures.

Claim 3

The coin dispensing apparatus of claim 1 in which the thickness of said first plate bordering its coin receiving apertures is substantially equal to a whole integer multiple of the thickness of the coins being dispensed.

Claim 4

The coin dispensing apparatus of claim 1 which means are provided for sensing the occurence of a rotation-impeding coin jam at the interface of said plates and providing a signal to said power means reversing the previous direction and continuing rotation of said plates in the reversed direction until the next jam occurence sensed by said means provides a signal to said power means again causing reversal and continuing rotation of said plates in the new direction.

Claim 5

The coin dispensing apparatus of claim 3 in which the thickness of said first plate bordering its coin receiving apertures is substantially equal to a whole integer multiple of the thickness of the coins being dispensed.

Claim 6

The coin dispensing apparatus of claim 1 including a control means for controlling the transfer of rotary motion from said power means to said plates, said control means including switching means for reversing the direction of rotation of said plates upon the occurence of a rotation-blocking coin jam at the interface of said plates and subsequently maintaining said reverse rotation until the next jam whereupon rotation of said plates is again reversed.

Claim 7

The coin dispensing apparatus of claim 5 in which said power means is a reversible electric motor and said control means senses a coin jam by utilizing the resulting abnormal current rise in the stalled reversible motor to thereupon reverse the direction of rotation of said motor and consequently said plates and subsequently maintain said reverse rotation until the next jam whereupon rotation of said plates is again reversed.

Claim 8

The coin dispensing apparatus of claim 5 in which said control means senses a coin jam by means of driving and driven clutch members having mating toothed faces spring biased into engagement but moved axially out of engagement upon a coin jam at said rotating plates, and a motion transfer member for transferring the said axial motion to said switching means.

Claim 9

The coin dispensing assembly of claim 5 having a preset counter component which provides a signal to said power means halting its operation after the preset number of coins fall through the registering apertures in said plates.

Claim 10

The coin dispensing assembly of claim 8 in which said counter component is in dual channel form and in which a comparator and a latch component are provided to latch open until reset the energizing circuit to said power means whenever the counts seen by said comparator component in each of said dual channels are other than equal.

Claim 11

The coin dispensing apparatus of claim 1 in which registering apertures in said first and second plates are circular in configuration and of substantially identical. diameter.

Claim 12

The coin dispensing apparatus of claim 1 in which said power means includes a spur gear rotated with one of.. said plates and a meshed driven gear rotated with the other of said plates said gears being sized to rotate said plates at the same angular velocity.

Claim 13

The coin dispensing apparatus of claim 1 in which a stationary back-up plate underlies said second plate which is the lowermost of the two rotating plates, said back-up plate having a drop-through coin aperture which successively registers with the coin accommodating apertures in said lowermost plate as it rotates, said back-up plate drop-through aperture being outside the overlapping area of said rotating plates.

Claim 14

The coin dispensing apparatus of claim 11 in which said rotating plates take the form of flat discs with said second rotating plate being seated in a recess in said back-up plate.

Claim 15

A coin dispensing assembly comprising a frustoconical hopper containing randomly positioned coins, a circular primary plate forming the lower lesser-diameter end of said hopper, said primary plate being supported for rotation about an axis normal to the plane of the plate, a secondary plate supported for rotation on an axis parallel to that of said primary plate and disposed in partial underlying relation to said primary plate, power means for rotating said plates in opposite angular direction, multiple coin receiving apertures formed in each of said plates with the apertures in each plate arranged equidistant from the respective axis of rotation of its respective plate, the circles formed by a line joining the aperture centers in said plates being tangential, a coin chute having its open upper end disposed adjacent the underface of said secondary plate for receiving coins in stacked relation dropped through the apertures in the secondary plate as they register with the chute, and a dispensing plate moveably supported adjacent the open lower end of said chute for displacing the stacked coins one-by-one sidewardly from said open end of the chute.

Claim 16

A coin dispensing assembly comprising a frustoconical hopper containing randomly positioned coins, a circular primary plate forming the lower lesser-diameter end of said hopper, said primary plate being supported for rotation about an axis normal to the plane of the plate, a secondary plate supported for rotation on an axis parallel to that of said primary plate and disposed in partial underlying relation to said primary plate, power means for rotating said plates in opposite angular direction, multiple coin receiving apertures formed in each of said plates with the apertures in each plate arranged equidistant from the respective axis of rotation of its respective plate, the circles formed by a line joining the aperture centers in said plates being tangential, a coin chute having its open upper end disposed adjacent the underface of said secondary plate for receiving coins in stacked relation dropped through the apertures in the secondary plate as they register with the chute, and a dispensing plate moveably supported adjacent the open lower end of said chute for displacing the stacked coins one-by-one sidewardly from said open end of the chute.

Claim 17

The coin dispensing assembly of claim 14 in which a stationary back-up plate underlies said rotating plates and has an inwardly off-set portion receiving said secondary plate, said back-up plate being provided with an aperture registering with said open upper end of the coin chute.

Claim 18

The coin dispensing assembly of claim 14 in which a stationry base plate is mounted in closely spaced relation to the discharge end of said coin chute, and said dispensing plate is mounted on said base plate and is moveable into the space between the coin chute discharge end and said base plate for edge-engaging coins at the discharge of said coin chute and displacing them one-by-one from alignment therewith.
