Extending vertically through the base plate 20 of the housing is a rotary drive shaft 47 having fixed thereon a toothed pinion 48.

In one side of the housing is mounted a horizontally extending rod 50 having the ends fitted in slots in the end Walls of the housing to permit transverse shifting of the rod. Tension springs 51 are connected to the ends of the rod 50 and "end to normally retain the same in an outwardly shifted non-operating position.

Slidably fitted on the rod 50 is an elongated rack structure 53 having a bar formed at the inner edge with rack teeth 54 designed to mesh with the teeth of the drive pinion 48. The rack 53 is designed to periodically engage the drive pinion 48 and to slide longitudinally on the rod 50. At the outer end portion of the rack is formed a tapering cam rib 55, the purpose of which will be later described.

On one end of the housing is mounted an enclosed annular casing 5'7 having a drum 58 rotatably supported therein. A helically wound spring 59 is disposed between the drum shaft and the circumferential wall of the drum and is secured to these elements. A flexible strip or tape 60 is wound about the exterior of the drum 58, one end of the tape being secured to the drum while the opposed end extends through a slot in the casing and is fastened to a hook 61 on the outer end of the rack 53. This spring drum mechanism is adapted to normally urge the rack to a starting position at one end of the housing and to restore the rack to this position upon completionof its gear driven movement. A rotatable and transversely slidable member B is adapted to shift the rack to a gear engaging position, this member embodying a shaft 63 and a right angular arm 64 at one end of the shaft. The shaft 63 is rotatably and slidably supported in upstanding bearing sections 65 of a support rack. Rigidly secured on the shaft 63, between the bearing elements, is a tubular sleeve 66 provided at one end with an enlarged shoulder. Coiled about the shaft, between the shoulder and one of the bearing elements, is a coiled compression spring 67 tending to normally urge the shaft to a predetermined position on the bearings.

To an intermediate portion of the shaft 63 is connected a lever 68 projecting radially from the shaft and having attached to the outer end a weight ball 69. A crank 70 is also connected to the shaft 63 and extends radially therefrom, the outer end of the crank being pivotally connected to one end of a link 71.

Secured to the coin receptacle 24 and extending longitudinally in the housing of the mechanism is an actuating bar 73. The intermediate portion of the actuating bar extends through and is fulcrumed on a slotted support bracket '74.

The inner end of the actuating bar '73 is pivotally connected to the end portion of a longitudinally projecting trip bar provided at its intermediate portion with an elongated slot '76. A pivot pin, attached to the bracket 39, extends through the slot '76 to support the bar 75. Adjacent one end, the bar 75 is formed in its underside with a tapered notch 77 operable to engage over the shaft 63. Adjacent the notch '77, the bar 75 is also provided with an upstanding lug '78.

To operate the mechanism, that is, to light a lamp 35 for a predetermined period of time. the patron inserts a coin of specified denomination into the top of the master coin guide or chute 23. During passage through the guide, the coin will drop into the intercepting receptacle 24, and, by force of gravity and the impact of the coin, cause depression of the receptacle. The lowering of the receptacle will cause the actuating bar 73 to swing vertically on the fulcrum 74 and cause elevation of the connected ends of the bars '73 and '75.

This operation will cause the notch '77 to disengage the shaft 63 so that a tension spring will slide the articulated bars 73 and '75 longitudinally to what will hereinafter be termed the rear end of the mechanism. The rear extremity of the bar 75' will force the trip arm 42 rearwardly and cause the'complementary arm 43 to disengage the lug 44 and permit the spring 40 to depress the lever 38 and contact block 33 downwardly. The movable contact 32 carried by the block will engage the switch bar 26 and thereby close the circuit between the source of electrical energy 36 and the electric lamp 35. The tilting of the actuating bar 73 will also, by the elevation of the notch '77 of the complementary bar '75, disengage the sleeve 66 so that the spring 67 is free to slide the shaft 63 transversely in the bearings. When the shaft 63 is thus actuated the arm 64, which assumes a depending position at this period of the operation, will engage and slide the rack 53 inwardly and into contact with the revolving drive pinion 48.

After the coin drops into the receptacle 24, the receptacle is moved forwardly until it assumes a position at one side of the auxiliary coin guide 22 and in registration with a slot thereof. The bottom of the receptacle 24 is inclined so that the coin is transferred therefrom into the chute 22 and dropped into a cash receiving container at the bottom of the guide. It will be apparent that the coin serves to break the pivot joint between the bars '73 and '75 and that the spring 80 immediately presses the joint ends of these bars downwardly on the sleeve 66.

The drive pinion, rotating at a selected speed, will move the rack through a forward timing stroke. As the rack approaches a completion of the timing stroke, the cam rib 55 will engage the arm 64 to slide the member B transversely against the action of the spring 67 so that the pivotally connected ends of the bars '73 and '75 slide off the sleeve 66 and onto the shaft, thereby holding the shaft in an extended arrangement. Upon completion of the timing stroke the arm 64, now disposed in an outwardly extended position, assumes a position against the rear edge of the cam rib so that the springs 51 move the rod 50 and rack 53 outwardly out of engagement with the drive pinion. At this stage of the operation, the spring rotated drum will act, through the medium of the tape 60, to slidably return the rack to its initial starting position at the forward end of the housing. During the restoring movement of the rack the arm 64 will, through the medium of the cam 55, be swung upwardly causing rotation of the shaft 63. As the shaft 63 is rotated, the weight 69 at the end of the lever 68 will be elevated from the bottom of the housing and the crank 70 likewise swung about the axis of the shaft. As the crank swings forwardly, it slides the connecting link 71 in the same direction and a pin 81 is slid along the bar 75 against the lug '78 and thereby forces the articulated bars 73 and '75 forwardly until the notch '77 engages the shaft 63.

As the cam is moved forwardly it releases the arm 64 so that the weighted lever 68 will drop downwardly by force of gravity to restore the arm 64 to its normal vertically depending arrangement.

This operation of the mechanism will enable the spring 45 to elevate the rocker mechanism and, as previously described, result in elevation of the movable contact carrying lever 38 so that the contact 32 is thus automatically moved out of engagement with the switch bar 26, thus opening the electric circuit and extinguishing the light.

Variation in the duration of the switch closing and lighting period may be effected by regulating the operating speed of the rotary drive shaft 4'? so that, upon the insertion of the coin a lamp may be lit for one hour, or other suitable period, and thereafter automatically extinguished. It is also contemplated to employ a plurality of switch operating mechanisms for operation of a series of lights, in which case the mechanisms could be arranged in vertically spaced positions controlled by coins inserted into the master guide or chute 23. As will be noted, the displacement of the coin receptacle 24 will cause a coin to drop uninterruptedly through the master guide at the station corresponding to an operating mechanism and proceed downwardly until it drops into the receptacle of a non-operating mechanism.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from thespirit of the invention or the scope of the subjoined claims.

Having thus described by invention, I claim:--
