This invention relates to apparatus actuated by tokens, such as machines for vending merchandise, or selling tickets, turnstiles, etc. More particularly, the invention is concerned with a novel token-actuated mechanism for controlling the operation of onev or more machines, which functions, upon receiving a genuine token, to cause suc-h machines to operate and does not respond to counterfeit tokens, so that the machines remain idle. The new mechanism may be employed for controlling machines in various combinations and a typical application of the mechanism for controlling a turnstile and a counting device will be illustrated and described in detail for purposes of explanation. It will be apparent, however, that the utility of the new mechanism is not limited to that particular use.
The mechanism of the invention is intended to be operated by tokens which can be activated by appropriate means so that they give off light. Such a token maybe a body of suitable material having a fluorescent coating which can be caused to glow when exposed to ultra-violet light. Another token that is suitable comprises a hollow body containing a quantity of one of the noble gases which can be caused to emit light by the action of a high frequency field, andsuch a token is described and claimed in our co-pending application Serial No. 545,852. filed July 20, v1944, which issued November l2, 1946, as Patent No. 2,410,845. Certain details of the new control mechanism will vary in accordance with the type of token to be employed but, since the necessary changes for the purpose are simple and will be readily understood, a form of the mechanism suitable for use with the token of our copending application is illustrated in the accompanying drawings.
The new control mechanism comprises a passage into which a token 4may be inserted, the token traveling through the passage by gravity. At one point in its travel, the token is acted on by means which are eiiective to cause a genuine token to emit light, and the light so emitted falls upon a photocell and causes the latter to develop energy. The current ow from the photocell is then amplified and the amplified current actuates a relay in` a power line.'v The line supplies energy to meansfor causing the token to be discharged from the passage and also to any other machine that it may be desired to operate. For example, in a turnstile installation, the line may supply energy, when the relay is closed, to a release mechanism for the turnstile and a counting device. Accordingly, when a genuine token is introduced into the passage, it is activated and gives oii` light as it moves through the passage. The light= so emitted causes a flow of current in the photocell circuit and the amplified current closes the relay so that the token discharge means, the turnstile'release mechanism, and the counting device are all actuated. If a counterfeit token is inserted into the passage, it is not activated and no current flows through the photocell circuit. The turnstile then remains locked, the counting device does not register, and the discharge mechanism remains idle, so that the token continues to the end of the passage Where it is returned to the person who inserted it.
For a better understanding of the invention, reference may be had to the accompanying drawings, in which Fig. 1 is a plan View of the mechanism;
Fig. Z is a View of the mechanism in perspective;
Fig. 3 is an end view of the mechanism with parts broken away; and Fig. 4 is a wiring diagram of the apparatus.
The new control mechanism comprises a passage I0 which is made up of a plurality of sections and may have its opposite ends disposed substantially in the same vertical plane. The mechanism is ordinarily mounted within a cabinet and may be supported by having the endsof the passage attached to the front wall il of the cabinet. For this purpose, both ends of the passage may pass through openings in the wall II and be secured in place by brackets I2, I3 which may be attached to the cabinet wall by screws I4. The upper end section I5 of the passage extends vertically andrhas an opening I5 into which a token I I may be inserted. The token then drops downward through the section I5 to enter an inclined section I 8, through which the token rolls. At its lower end, the section I8 is connected by a vertical section I9 to an inclined section 2! leading to the wall of the cabinet, the lower end 42| of section 2livl being open and terminating flush with the outer face of the cabinet wall.
The lower side of section I8 of the passage is connected to a vertical passage 22 which leads downwardly to a suitable receptacle within the cabinet. Communication between section I8 and passage 22 is controlled by a slide 23 which has a longitudinal opening 24 and is movable through aligned openings in the walls of the section. The slide is normally held in position to close the lower side of section I8 by a spring 25 attached at one end to the slide and at the other end to a bracket 26 secured to a side wall of passage 22. The slide 23 may be moved to bring its opening in alignment with the lower side of section I8 by means of a solenoid 21 having a plunger 28 attached to the slide. The solenoid may be supported in any convenient manner as, for example` on a bracket 29 attached to the side wall of passage 22.
The side walls of section i8 are formed with aligned openings 35, 3| near the upper end of the section, and a pair of high frequency coils 32, 33 are mounted in alignment with the openings on opposite sides of the passage. The coils are wound on forms 34, 35 respectivelyr and a photocell. is mounted in alignment with each coil and' with its sensitive element lying within the coil form.v 'Thef photocell 36 associated with the coil 32 is provided with terminals receivable in sockets. in a base 3l which is heldin place by pins 38, one of which extends through. an opening 39 in a bracket il attached to the side wallV oi passage 22. The other pin 38 passes` through an opening in bracket 25, and by moving the socket outwardly relatively to the brackets. the sensitivey element of the photocell 35 may be removed from within the coil form 3d, so that the photocell can be' freed. from the socket. The base 31 is provided with terminal screws 4I through which connections to its socket terminals may be made. Photocell or phototube 42 isk mounted on a base 43 at the end of coil 33 and. similar to base 31.- Base- 43 is supported on pins 415,. one of which extends` through an opening in bracket 45 attached to the side wall of passage section 22. The other pin 44 ex.- tendsthrough an opening in a bracket 46 attached to bracket 29.
In the simplified wiring diagram of Fig. 4, the highv frequency coils 32, 33 are illustrated with the token Il lying between them in position to be activated thereby. Current is supplied tothe coils by an oscillator tube 4l, they plate-of which is supplied from a source of direct current 48 at a voltage, for example, of from 90 to 135 volts. A radio frequency chokecoil 49 is placed in the plate circuit to keep radio frequency currents out of the power circuits. The lamentof tube 41 is heated by a suitable source of electric current, indicatedv by terminals U, 5|.
In operation, with no lighton thefphototube 42, there will be no current and thus no potential across Rl. Hence, the grid of the amplifier tube 52 will beV at the negative bus potential. Resistor R3 is adjusted to produce a cathode bias such that insuicient current. for operation will flow thru theA relay coil 53.
When a genuine token, in passing through pas-` sage section i, enters the space between coils 32, 33, the token is caused to emit light, and the light is picked up by phctocell 42. This light causes electron flow through the phototube l2y and resistor Rl will raise the potential of the amplier grid, permitting suiiicient current toi ow to operate relay 53. The setting of R3 and the. cathode bias determines the phototube current.` and the voltage drop across Rl necessary to raise the amplifier grid potential sufficiently to causer relay operation. Y
The duplex type 11'7P'7 (or 117N'7) tube is shown for tube 52. This tube is a combination rectifier and pentode with a cathode heater for operation directly from an A. C. line of approximately 5 117 volts (terminal 54).
The electrodes on the right side of tube 52 comprises a half-wave rectier. Resistor R8 is a small protective resistor in the plate lead. R1 and the two capacitors C2 form a Pi filter to supply direct current to the amplifier side.
Resistors R3, R4, R5 and R5 with capacitor C3 paralleling R3 and R4 combine to form a voltage di'v'ider circuit to furnish proper cathode and screen potentials and also variable grid bias l5= potential.
From the cathode on the left side of tube 52, and thru: the controlling grids and screens i'o its corresponding'. plate, a circuit is set up to the associated coil 5320i the relay. These form the amplier andrelay circuit.
Resistor R2 connected in series with phototube 42 and the control grid and cathode of tube 52 form the control circuit.
Series resistor RI is a contributing factor needed to control the grid of tube 52 in conjunction. with variabley resistor 53.
The phototube protective resistor R2 protects the phototube against overcurrent drawnv via the amplifiercathode-grid circuit in the case of' an extreme amount of light on the phototube. Ca-
pacitor CL protects againstvvery short transient light or electrical surges that might cause false operation or chattering of the relay.
The closing of the top seti ofr contacts, designated 55', of relay 53, connects the power source 54 to the turnstile 56, and thel current operates a solenoid which releases a locking dog and permits the turnstile to be entered bythe depositar of the token. On closingP of the second set o1 n contacts 51, current is supplied to accounting device 58 which registers the. admission. The closing of the bottom set of contacts 59 energizes solenoid 21 which moves the slide 23. The turnstile solenoid, the counting device, and solenoid 21 are allv connected to the common or neutral wire 6l),
With. the apparatus described, when a genuine token is introduced into the passage l5, theY glow which it is caused to emit by the high frequency field through which it passes results in the turnstile being released, the countingv device. actuated, and slide 23- moved so that the tokenr will be diverted from passage I5 and enter passage 22. The person. who deposits may then. pass through the turnstile and his admission is registered on the counter. If a counterfeit token is inserted in the slot, it willl not emit light on eX- lposure to the high frequency field, and relay 53 will, accordingly, remain. open. The turnstile G0 will, therefore, remain locked, no admission will be registered,v and slide 23 will remain in position to cut off communication between passage section I8 and passage 22. The token willl then continue through passage. sections I8, I9, and
20 and be returned to the depositor at the front of the cabinet through opening 2|.y
In the construction shown in Fig. 1, two photocells are employed so that the mechanismy will function even though one photocell: becomes inoperative. Inv the wiringY diagram, only one photocell has been shownV but the use of the other and the connections therefor will beV readily understood. In the event that the apparatus includes only a single photocell andv that photocell bceme inoperative 0r both phetopll bwme inoperative in an apparatus equipped with two cells, a token of any kind inserted in passage I5 will not actuate the mechanism and will simply continue through the passage to be returned at the front of the cabinet.
As pointed out above, the mechanism disclosed is intended to be used with a token which can be activated by exposure to. a lhigh frequency field and thereby caused to give oi light. The particular token for which the mechanism illustrated is intended is that disclosed inour co-pending application and comprises a hollow body containing a noble gas which will glow in a high frequency field. It will be apparent that tokens of other types may be used as, for example, the token may carry a body of fluorescent material which will glow when exposed to ultra-violet light. If the apparatus is used with such a token, the high frequency coils are replaced by means for directing a beam of ultra-violet light upon the token as it passes through passage section The control mechanism may be employed for the control of various machines other than those described as, for example, the mechanism may control a device for printing and delivering a ticket to be used in pari-mutuel betting. In that application, the control mechanism controls not only the printing device, but also ordinarily controls a totalizer or counting device as Well as the means by which a genuine token is retained and a counterfeit token is returned to the depositor.
