This invention relates to mechanism adapted to be controlled. by an inserted coin or the like, 'preferably through then medium of a switch, which is acted upon by the coin to close an electric circuit. v

The general object of provide an improved devic'eof this character, in which the coin closes the switch and holds it closed until the coin is caused to release the switch bythe action of suitably timed mechanism operated by an electric current passing through said switch. The device is so arranged that a plurality of coins may be -inserted at one time and as soon as the opera- 154 tion initiated by one of these coins has been completed, the 'next coin is in position to hold the switch closed until the completion'of the next operation. If more than a predetermined y'number of -coins are inserted at one time, however, all coins in excess of such number will be immediately returned, to the operator through a supplemental outlet opening from the chute which leads to the switch. The important features `of my invention and its mode of operation will be more specifically explained in connection with the accompanying drawing, in which the single figure is a view partly in elevation and partly in section having a diagram of the wiring associatd therewith. v As illustrated in the drawing, the device to which my Kinvention relates comprises a chute 1 which is Vadaptedto receive a number of coins 2. At one side of the chute near the lower end thereof, is a.v stop pin 3 against whicheach successive coin lodges. The opposite side of the chute terminates some distance above the pin 3 as indicated at 4.

An insulating block 5 is located near the side of the chute and has abracket 6 secured thereto and extendingtoward the chute. An insulating member 7 is pivoted in the bracket A 6 asl indicated at, 8, and carries a switch blade 9 which carries a contact 10 adapted to engage a fixed contact 11 secured in the block 5. The switch 9, however, is adapted to be held normally open by a' comparatively light spring 12 which bears against the block 5. A spring "iinger-13fstronger than the-spring 12, is secured to the insulating member 7 and extends the invention is to nection 24. This timing me a train of speed reduction gearing 25 which 8o downwardly adjacent the open side of the chute, terminating in a curved end 14 which is in opposed relation to the stop pin 3. Vhen the chute 1 is empty, the spring 12 holds the switch 9 open. 'The first coin in- 55 serted lodges between the pin 3 and the curved en d 14 olf-the spring inger and closes the switch against the comparatively light resistance of the spring 1/2. One or more coins, however, up to the capacity of the chute, are 6o not suiicient to overcome thelresistance of the spring 13, so as to' pass the same, unless ejected by some force other than gravity.4

Electric current is 'supplied by wires 15 and 16. When the switchl 9 is closed a circuit 65 is completed from the wire 15 through wire 17, switch 9, contacts 10 and 11, wires 18 and 19, motor 2O and wire 21, which is connect'ed to the wire 16. 'Thus the motor 20 is driven as long' as thezswitch 9 is closed. 70 Branch wires 22 and 23 lead rfrom the wires 18 and 21 respectively to a radio receiving set, phonograph, music' box, or 'other'electrically operated device, which Will be loperated only as long as the closed.

The motor 20 is adapted to drive a'timing mechanism by means of a suitable drive conchanism includes rotates a crank disc 26 in the 'direction indicated by the arrow. This disc 26 is provided e with a wrist pin 27 on which an ejector armV 28 is pivoted. The rearend of this ejector arm isconnected by suitable means, such las the spring 29, to a fixed point 30, sothat as 1t is carried about the axis of the disc 26, the spring 29 has a tendency to'hold the tree end 31 of the ejector arm toward the chute 1. The side ofthe chute above the pin 3 is formed '3U with an opening 32 through' which the free end 31 of the ejector arm is projected.

From the foregoing description, 'it will be seen 'that as a coin is inserted in the chute Y 1, itcloses the switch 9.and sets the motor 20 95 in operation;` After 'a predetermined period of time, the operation of the motor rings the ejector arm 28 into the position shown' in the drawing, in which it engages the lowermost coin 2 and forces the same past the 100 switch 9 remains 75 I i silient portion engageable by the coin, a fixed ystop 3 in opposition to the spring 13, thusV other coin inthe chute,

places the ejected coin and retains the switch.

releasing thel switch 9 and allowing it to open under the influence of spring 12 unless there is another coin in the chute. If there is anit immediately re.-

in closed position, until the motor 2() and ejector army28 are moved through another cycle. This operation continues as long as there is a coinremaining in the chute.

Itwill be seen, therefore, that a number of vcoins may be placed in the chute simultaneously up to the limit of its capacity and the coin controlled mechanism will operate automatically for a period of time in proportion to the number of coins inserted. If,

however, coins are inserted beyond the capacity of the chute, they will be deiiccted from the chute through a branch opening 33 and will lbe returned to the operator.

vWhile I have shown and described in con` siderable' detail the preferred form of lthe invention, it is to be understood that the same may be. modified within the scope of the' through a predetermined cycle and) project it into the e'ect the coin t e switch.
