COIN-CONTROLLED MECHANISM.

Application filed December 30, 1920. Serial No. 434,032.

To all whom it may concern:

Be it known that I, Roscoe ROYAL, a citizen of the; United States, residing at Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Coin-Controlled Mechanism, of which the ningto the coin box.

following is a specification.

My invention relates to coin controlled mechanism in which forcing a coin through the coin slot assists the parts in closing an electric circuit for driving an electric motor such as a fan motor when a predetermined number of'revolutions of the shaft of the motor will in turn be assisted by suitable gearing to open the electric circuit in restorin; the coin mechanism to normal.

. The object of m invention is: (a) to furnish an improve means of collecting a coin for use of an electric fan for a predetermined time or number of revolutions of fan; (b) to provide for collecting a number of coins successively at one time for extended use of the aforesaid fan motor for a multiple of the predetermined time in accordance with the number of coins dropped up to a given limit, say ten; and

(c) not to re ister further coins till part or all of the predetermined time has been worked out.

A form in which my invention may be practiced is illustrated in the accompanying drawings in which Fig. 1 represents a general working outlay of the parts. Fig. 2 shows an arrangement of parts to close the circuit of the motor.

Referring to Fig. 1: 4 represents the frame of the coin box, 3 represents the frame of the gear casing at the motor shaft, 6 rep resents a flexible shaft or wire and its flexible housing 7 running between the two frames. Conductors 8 and 9 to complete the circuit of motor M also are shown run- I At .V is shown the last deposited coin in place. The form of coin box I have preferred to illustrate is such that the last coin deposited is held in place forview as to quality if des1redthe preceding coin in each instance being used to operate the circuit closer by the aid of the succeeding coin as will be shown. At Pisa push button projecting through the top of the box normally held upward by rod 14 working through slot 17- and pressure of spring 15 against stop 16; Push button P is arranged to be pushed downward the length of the coin used so when the first coin is passed through slot S into continuation of slot T it will drop as far as permitted by spring 45. Application of pressure from push button P will force the coin past spring 45 into position at V ready ,to engage with projectiug arm 19. As before mentioned, one coin is retained in the coin box so the mechanism is operated not by the first coin but by every coin thereafter. The next coin dropped in slot S represented dotted at 5 will obviously when forced downward by push button P transmit a downward movement to coin V which in passing to coin box will momentarily push the lower end of projecting arm 19 aside from obstructing the coin slot T. The arm 19 pivot- .ed to the frame t at 20 and coupled at its upper end to arm 23 carrying the tooth 24 will when moved against tension of spring 22 out of normal position with lower end obstructing the coin slot T, change the position momentarily of the arm 19, arm 23 and tooth 24 resting against stop 25 to locations represented by dotted lines so that tooth 2 1 is ready to engage a tooth of wheel 10. On forcing the coin V past the lower end of projecting arm 19 and into the coin box 4:7, arm 19 tends to return to normal, relieving theipull from arm 23 so spring 22 tending to retract arm 23 causes tooth 24 to engage a tooth of wheel 10 and move wheel 10 one tooth in direction of arrow, placing a succeeding tooth under lower pellet of escapement 26 under pressure of spring 27 and arm 23 and tooth 24 return to normal against stop 25. This same movement of wheel 10 moves insulation 31 attached thereto under spring 12 bringing it into contact with spring 11 closing the circuit of motor M through rheostat R, conductor 9, spring 11, spring 12, conductor 8 to the mains.

The action of springs 11 and 12 in the circuit closing operation is also shown in Fig. 2. r

As the motor runs, shaft 33 which is the motor shaft and carries the fan, revolves, turning screw 3 f meshed with saw tooth wheel 35 running on pin 37 and carrying pinion 36 in mesh with wheel 38, revolving on pin 4&1 carrying hub 39 and cam 40.

fan a predetermined interval. Pivoted to frame 3 at 43 is arm 41 pressing against hub 39 ready to engage with cam 40. At the upper end of arm 41 wire 6 is attached at eyelet 42. At its further end wire 6 is attached to double escapement 26 by spring 28. Spring 29 applies tension 'to draw wheel 10 to normal. As wheel 38 revolves cam is brought about to force arm 41 outward, pulling wire 6 applying tension on spring 28 to pull upper pellet of 26 to engage with wheel 10, allowing the escapement of tooth by relieving the lower pellet from engagement with wheel 10. On further revolution of'wheel 38 the cam 40 allows arm 41 to return to rest against hub 39, allowing wire 6 to move back relieving tension on'spring 28 which in turn allows spring 27 to draw back double escapement 26 relieving upper pellet thereon from engagement with wheel 10 and allowing the latter to drop back another half tooth. In thisinstance the wheel 10 is at normal, the projection 30 thereon touching stop pin 49. The insulation '31 also moves from under spring 12, breaking the circuit of the motor.

It is obvious from the drawing that the wheel 10 may be advanced a reasonable number of steps by the use of successive coins till the space 50 comes to double escapement 26 when no further advance will be possible regardless of how many coins are deposited.

I do not limit myself to the details as set forth in this description as many changes could be made in the apparatus and arrangement without departing from the spirit of the invention.
