COIN CONTROL DEVICE n INVENTOR. (mm .5: .7. #044,

L0 LIN- j filin s 5x2 'The coin arresting arm claw a 36 there is a coin retaining lever provided at one end thereof with a follower 31 engageable with the cam 33., At ,the other end .of said lever which extends downwardlyand under the coin box |0 there is provided a coin arresting arm having a claw with a plurality of laterally and upwardly extending tynes 38. Said tynes are arranged to extend under the coin slots to receive the re spective coins therebetween. The coin receiving spaces between the tynes are of such depth relative to the diameter of the respective coins that although said coins will be received therebetween and permitted to drop sufficiently far to engage and rest upon their respective fingers 2.9,they will not be permitted to entirely pass therethrough.

flhus, when the claw is in its normal forward position; the coin will be restrained thereby to rest upon its finger 29"and by it weight cause its switch lever to hold its switch contacts in closed position.

to the housing 3| and' the other end to the downwardly extending claw arm. Thus, upon rotation of the] cam by the motor, said cam through the 7 action ofthespring will retract the claw after a"" ,coin arresting arm fulcrumed on said mechapredeterrnined interval of time, to permit the restrained coin to'drop free. of itsswitch closing finger 29, whereupon the actuated switch will spring to openposition. Afterthis lapse of time,

the cirouitcontrolled by said switch will have completed its function. V l

diagrammatically The motor control, circuit is illustrated in Fig, 3 as applied to a multlcoin selectivephonograph. Closing of any one of the coin switches 2|,22, or 23, completes a circuit from ground through one of the contact arms,

a, b, or .gand arm d, all rotatably mounted on a common mountingplate 40, then through the coin, relay coil H to a 24 volt relay, supply 42.1 This energizes the relay coil 4| which is then '45 maintained in an 'operating condition by the interlockcontacts t3 which are in series with the ing-.of the isolation registration contacts 41 by 'relay 4| controls the phonograph accumulator not here involved.

.As thejmotor '3llrotates, the contact arms, a, 5 o, and d,'relay llimit switch 35 and motor limit switch 3I4 r o tate withiit on shaft 32, As the contact armsrotate, the short arm d moves from contactv segment No. [and contacts segment No. 2. I K

At the same timethe long contact arms, a, 1), 6

and 0, move into engagementwith the small contacts, 6, l, andB, wired, in parallel with contact ,segments 3,, 4, and 5. .This provides a pulsing circuit to the accumulator 00114!) which evaluw atesthe coin to register the number of record' plays corresponding tothe closed coin switch 2|,

22, or 23, After the contact arms 'have'passed the last 'coin registering contactin the circuit, the coin retainingtynes 38 release the coin, open- ;ing the coin switch and shortly thereafter the Q relay limit switchi35opens and releases the coin relay 4|. Followingthisaction the motor limit "switch- 34 opens and stops the motor 30 which hasc'ompleted one full 'cyc'le.'

The follower ill "is biasedagainst the cam 33 5 'by'a tension spring 39 having one end connected m1 likewise the 73 switches 2|, 22 and 23, according to the coin oi coins deposited, will be respectively held in retaining and closed positions, as shown in Fig. l, for such interval as is required for the follower 31 to move over the outer dwell of the cam 33. The follower will then drop to the inner dwell of the cam, causing release of the coin and retaining the claw in its retracted position for a time interval, whereupon the follower will ride to the outer dwell which will reset the claw to its coin retaining position.

Whereas the above described structure is illustrative of one embodiment of the invention, it is believed obvious that various devices may be employed in place of the motor driven cam for moving the restraining claw to coin releasing position after a predetermined interval of time;

similarly electromagnetic means may be employed, all to the end that upon a circuit being initiated by the coin, the coin will be restrained I in circuit closing position for such time interval as to permitof electrical saturation of the circuit and the magnetically actuated devices thereof.

The invention claimed is: v I

1. In a motor controlled coin arresting mechanism having a plurality of adjacent coin passages each adapted to receive a coin of a different denomination, atiming motor and an electric circuit therefor, the combination therewith of a nism intermediate its ends, one end thereof terminating in a plurality of laterally extending tynes below said passages for receiving the respective coins therebetween, a cam driven by said motor engageable with the opposite end of said arm, a series of control switches in said circuit biased to normally open position, and aswitch control lever associated with each switch normally biased toa position under one ofthe spaces between said tynes for receiving and supporting a coin between said tynes, the weight of which is adapted to close its associated switch, said. cam being operable to swing said arm from coin arresting position after a, predetermined time interval determined by said motor to permit said coin to drop from its supporting lever and the return of its associated switchto normal open position; v a

2. In a motorcontrolled coin arresting mechanism having a plurality of. adjacent coin passages each adapted to receive a coin of a different denominatioma timing motor and an electric circuit therefor the combination therewith of a coinarrestingarm .fulcrumedon said mechanism intermediate its ends, one end thereof terminating in a' claw having a plurality of spaced tynes extending below said passages between which said'coins are received, a cam driven'by said motor engageable with a cam follower on the opposite end of said arm, a series of spring leaf control switches in said circuit normally sprung to. open position, and a 'switch'control lever fulcrumed on said. mechanism; intermediate its ends associated, with each switch with one end thereof normally biased to a position under one of the spaces between said tynes for receiving andsupportinga coin inassociation with the claw of. the'coin' arresting arm, the weight of the coin on said lever forcing the opposite end thereof against itsassociated switch to move one ofits spring leaves to circuit closing 'position and thereby cause said motor to be driven, said cam beingfloperable' by said motor to swing said arm from coin arresting position after passages for receiving the respective coins therebetween, a normally open spring leaf switch in 15 said circuit associated with each space between said tynes, the depth of the space between said switch and said tynes in relation to the diameter of the coin received therebetween being adapted to arrest the passage of the coin therethrough and hold it in switch closing position, a cam driven by said motor engageable with the opposite end of said arm for retaining said tynes in coin arresting position with respect to said switches and permitting said tynes to be withdrawn from coin supporting position for coin release therefrom after a predetermined time interval determined by said motor, the release of said coin by the withdrawal of said tynes relieving the coin pressure on said switch to permit it to open the circuit to said motor.
