COIN-HANDLING MACHINE.
Specification of Letters Patent.
Patented Sept. 12, 1916.
To all whom it may concern:
Be it known that I, RICHMOND M. MoGEn, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Coin-Handling Machines, of which the following is a full, clear, concise and exact description.
My inventlon relates'to a coin handling machine, and more particularly to a machine which is adapted to retain a coin deposited in'the machine,-and return, if desired, any amount of change up to the value of the coin deposited.
One of the objects of my invention is to provide a machine which will permit of inspection of a coin tentatively deposited therein; which will, if the coin be acceptable, deposit the coin in the receptacle provided therefor; which will register the amount of a payment to be taken from the coin, and will return as change the diiference between the amount registered-and the value of the deposited coin.
-Another object of my invention is to provide a machine which, in certain instances, is adapted to register the amount of a payment and the denomination of the money or other currency used in making the payment, in order that in such cases it may not be necessary for the money to pass through the machine, but which will, nevertheless, afford a check upon the operator of the machine.
While I have shown my invention as embodied in an electrically actuated machine, there are many features thereof which are entirely independent of such particular embodiment of the invention and which are capable of embodiment in types other than electrically actuated machines.
It will also be noted that my machine comprises a novel combination of elements, some of which in themselves constitute novel sub-combinations.
The machine of my invention is capable of a variety of uses, such, for example, as a fare register for street cars, for handling money paid for admission to a theater or the like, and in general for handling coins tendered in payment and from which change, if required, is to be returned to the person tendering the coin.
In the particular machine hereinaftershown and described, the mechanism is so arranged that normally when a coin is deposited in the machine or a bill is tendered to the operator of the machine, a five-cent fare will be registered and the requisite amount of change will be ejected from the machine. That is to say, if a five-cent piece be tendered, it 'will be registered and deposited, no change being returned, but if a ten-cent piece or any larger denomination of money be deposited, a five-cent fare will be registered and the required amount of change be returned from, ,the .machine. However, the machine is sd'designed that any required number of fares may be registered as taken from a given coin. Thus manually operated means, for example keys, are provided for designating the particular number of fares that are to be registered. For example, if a ten-cent piece is deposited iirrthe machine and it is desired to register two fares, this may be done, in which case no change will be returned. Likewise, with respect to any coin of a still higher denomi-v nation, the required number of fares may be registered and the change, if any, be ejected from the machine. I
My invention will be more fully understood by reference to the accompanying drawings, in which- Figure 1 is a front elevation with the caslng removed and having portions of the framework broken away to more clearly show the working elements; Fig. 2 is an end elevation taken from the left hand side of the machine; Fig. 3 is an end elevation taken from the right hand side of the machine; Fig. 4 is a back view in elevation, with portions of the framework broken away; Fig. 5 is a view in front elevation, with the coin tubes and coin contact box removed showing the mechanism for setting up the change-making combinations; Fig. 6 is a back view showing the mechanism for unlocking or looking one set of combination bars and looking or unlocking another set; Fig. 7 is a central, vertical section taken on the line 77 of Fig. 5; Fig. 8 is a plan view, certain portions having been removed for the sake of clearness; Fig. 9 is a plan,
line 11-11 of Fig. 7; Fig. 12 is a similar view taken on line 1212 of Fig. 7; Fig. 13 is a bottom view of the coin ejecting mechanism; Fig. 14 is a fragmentary, vertical section showing the lower end of the combination plate in section and showing the means for removing all of the coins simultaneously; Fig. 15 is a sectional view taken in the line 1515 of Fig. 7; Fig. 16 is a similar view taken in the line 1616 of Fig. 7; Fig. 17 is a transverse, vertical section taken on the line 1717 of Fig. 16; Fig. 18 is a vertical section on the line 18-18 of Fig. 4; Fig. 19 is a plan view of the mechanism shown in Fig. 18; Fig. 20 is a diagram showing the electrical circuits which control the operation of the machine; Fig. 21 is a front elevation of a modified form of my invention, portions of the mechanism being omitted, showing mechanism for looking the plungers, means for signaling when the coins have reached either the high or low stage in the deposit tubes, and means for loading the machine without'operating the registering mechanism; Fig. 22 is a fragmentary, horizontal section through the deposit tubes shown in Fig. 21, showing the closures for said tubes in an open position; Fig. 23 is a plan section taken through the plunger stems on line 23-23 of Fig. 21; Fig. 24 is a vertical section on line 24-24 of Fig. 21; Fig. 25 is a detailed, perspective view of one of the tube closures shown in Fig. 21; Fig. 26 is a fragmentary, detail of a modified form of combination bar; Fig. 27 is a central, vertical section of a modified form of inspection chamber on the line 2727 of Fig. 28; Fig. 28 is a rear elevation of Fig. 27; Fig. 29 is a plan view of Fig. 27; and Fig. 30 is a vertical section on the line 303O of Fig. 27.
Referring more particularly'to Figs. 1, 2, 3, 4, 18 and 19, it will be noted that there is mounted upon the top casing of the machine a coin-receiving box 1, having an operating lever or handle 2, secured to a rockshaft 3, said lever having an arcuate slot 4 which receives a pin 9 carried by a crankarm 5 mounted upon one end of a rod 6. Upon the rod 6 is mounted a pair of brackets 7, 7, which carry a table 8 (see particularly Figs. 1 and 18). When the lever 2 is depressed, the upper portion of the slot 4 engages the pin 9 upon one end of the crank 5 and causes the table 8 to tilt its front end upwardly. The brackets 7, 7, have a fiattened portion 10 (see Fig. 18) which, when the rod 6 is turned, will force the spring pressed plate 11 away from its perpendicular position and provide an opening at the rear of the table 8, allowing any coin which may have been inserted through the chute 12 to fall into the chute 13. The plate 11 is loosely hung upon a rod 14 and is apertured to allow a tension spring 15 to pass over said rod and bear against the rear side of plate 11, the function of spring 15 being to hold the plate 11 against the bracket 7. The plate 11 is provided upon its front face with a guide 11 to guide the coin to approximately the center of the table 8. Upon the rock-shaft 3 is mounted a collar 16, (see Figs. 18 and 19), having a cusp or tooth 17, which, when shaft 3 is rocked, allows the spring controlled lever 18 to thrust a closure plate 19 into the chute 12, thus preventing the user from inserting a coin except when the machine is ready to receive a coin. A glass front piece 20 permits of the operator inspectingacoin which has been dropped upon the table 8; and if said coin appears to be faulty, it may be withdrawn from the machine by raising the lever 2, which will actuate the arm 5 in an opposite direction from that previously de scribed, and the front edge of the table 8 will be depresed and the coin will fall from the machine. This latter operation does not affect any of the interior mechanism of the machine. Referring more particularly to Figs. 2, 3 and 18, upon the shaft 3 is also secured an arm 21, having a down-turned end 22, which is adapted to project through the slot 22 in the cover of the coin box to actuate the lever 127 which engages the upper end of an arm 23 for the purpose of unlocking the combination bars which will be hereinafter described. A coin deposited in the chute 13, in the manner heretofore described, passes through a chute 24 and drops upon an inclined laterally movable track 31, which projects through a panel 25 (see Figs. 1 and 16). Mounted upon said panel above the track 31 are a series of electric contacts 26, 27, 28, 29, 30, which are adapted to caliper coins of varying sizes, as for example, coins of the denomination of a dime, a five-cent piece, twenty-five cent piece, fifty-cent piece and a dollar, respectively. A coin, after reaching the removable inclined track 31, rolls down thereon until it reaches a contact point which calipers it, and the coins are thus sorted according to their denominations. The inclined table 31 is so constructed that it may be withdrawn from beneath the coin, thus causing the coin to fall into one of a series of magazines or tubes which lie directly below the contact at which the coin is arrested, the tubes 32, 33, 34, 35 and 36 cooperating with the contacts 26, 27, 28, 29 and 30, respectively. A coin, when it is arrested by one of the contacts 26, 27, 28, 29, 30, thereby closes a circuit for an electro-magnet or solenoid 37, which circuit will be hereinafter traced. The energization-of said solenoid causes it to draw in its plunger or core 38 (see Figs. 3, 8 and 20).- Pivotally secured to the outer end of the plunger 38 is an arm 39, whose opposite .end is secured to a vertical rock-shaft 40,
to which is also secured .an arm 41. The end 42,.on the arm 41, is of insulating material and engages a slide bar 43, (see Figs. 15, 16 and 17 which is adapted to reciprocate in bearings 44, 44, mounted upon the back of the plate 25. The track 31' has formed upon its rear edge a pair of arms 45, 45, (see Fig. 16) which have depending pins 46, 46, which engage oblique slots 47, 47 in the slide bar 43, so that as the slide bar 43 is reciprocated against the tension of spring 48, it causes the track 31 to be withdrawn from beneath the coin and allow the coin to be deposited in the corresponding coin receiving tube. Upon the inner end of the lever 39 is a spring pressed finger 49, (see Figs. 3 and 8) which engages and shifts a spring retracted switch lever 50 of a circuit changer 51. (See also Fig. 20.) This breaks the circuit through the coin in a manner which will be hereinafter described.
Inasmuch as, in the particular embodiment of my invention shown in the drawings, the machine-is designed to retain at least the value of five-cents from the coin deposited, there is no change returned from the five-cent piece. If, however, a coin of a larger denomination than a five-cent piece is inserted, it will follow the same course that the five-cent piece takes except that it will close an electric circuit between its corresponding contact and the table 31. In each case the solenoid 37 is energized and the coin dropped into its appropriate magazine in the manner just described. However, provision is made whereby, when the coin is of a denomination higher than a fivecent piece, change may be returned by the machine. The closure by the coin of the circuit between the track 31 and one of the contacts 27, 28, 29, 30 will, under appropriate conditions, bring into operation the change-making mechanism, which will now be described.
Referring more particularly to Figs. 5, 7, 11 and 12, the panel 52 of the combination setting up mechanism has a series of vertical and a series of transverse channels 53, 54, respectively. In the channels 53 are slidably mounted the vertical bars 55, 56, 58, 59, which carry upon their lower ends the rings 60, 61, 62, 63, 64, respectively, constituting closures for the corresponding magazines. Slidably mounted in said transverse grooves of the panel 52 are combina= tion change-making bars, hereinafter deicribed, which cooperate with said vertical ars.
By way of illustrating the operation of the machine, assume that a dime is inserted and it is desired to return five-cents in change. The dime, when calipered between the contact 26 and the carriage, closes a circuit for the solenoid 65, which circuit is shown in Fig. 20 and will be hereinafter draw down one end of said lever 69. A rod '70 is pivoted at its lower end intermediate the ends of the lever 69 and at its upper end is pivoted to a bell crank lever 71, whose vertical member. 72 is connected to a short combination bar 73 slidably mounted in one of the transverse channels 54 of the panel 52. (See Fig. 5). Said bar 73 has a cam notch 74 cut in its upper edge. A block or stud 75, secured to the vertical bar 56, engages the notch 74, and is adapted to be raised when the bar 73 is moved beneath it. Inasmuch as the block 75 rises, the bar 56 upon which it is mounted also rises and this raises the ring 61 carried by said bar an amount equal to the thickness of a five-cent piece. The tube 33 is cut away on its bottom end. as are likewise the other tubes, as shown in Fig. 7 at 76. Simultaneously with the raising of the ring 61, a pair of changeejecting magnets 77 are energized, the circuit of which will hereinafter be described, thus drawing in their plungers 78-. (See particularly Figs. 4, 7 and 12). The plungers 78, 78, carry upon their rear ends a plate 79, having a series of upstanding fingers 80 which are adapted to actuate a series of change-ejectors 81. Each changeejector 81 is slidably mounted in a rearwardly extending foot 82 of its corresponding bar 55, 56, 57, 58, 59 (see Fig. 7). In order that the change-ejector 81 may be free to rise with the foot 82, it is provided with a depending end 83 which projects through an opening in the inturned end 84 of the finger 80. The ejector 81 is thus free to be lifted with the foot 82 and is at the same time adapted to be actuated by the movement of the plate 79. WVhcn the bar 56, for example, is raised through the coiiperation of the notch 74 and block 75, the change-ejector 81 is likewise raised an amount equal to the thickness of a five-cent piece. The other change ejectors 81 of the series remain, in the case assumed, in their normal position, that is, just clear of the lower surface of the coins in their respective tubes. Therefore, when the plungers 78 are drawn in by their solenoids, the fivecent ejector 81 engages a five-cent piece and pushes it from its tube 33 onto a refunding chute 90, from which it passes through the opening 91, to be returned as change.
The mechanism next to be described is that which selects the combination bars to make the proper change from any coin which has been deposited in the machine. The means for designating the combination bars to be actuated in the present instance is a keyboard comprising two series of keyplungers 92, 93. These plungers are supported from a vertical panel 94 (see Fig. 7) which carries contact-supporting blocks 95, to which are secured electric contacts 96, adapted to be engaged by contact springs 97, carried by the several plungers. The plungers are held in their normal position by springs 98, which rest upon angle supports 99, 100, said plungers being limited 1n their upward movement by the collars 101,
102, which abut against angles 103, 104. When any key is depressed, for example a key in series 92, its collar 102 will engage a finger 105' mounted upon a rock-shaft 106, the outer end of said rock-shaft being connected through suitable link and gear mechanism with a counter 107, (see Fig. 4), which will register the number of five-cent fares to be taken from any coin inserted in the machine. The end of each of the fingers 105 is so spaced with respect to its coiiperating collar 102 that when the corresponding plunger 92 is depressed, the rock-shaft 106 is turned an amount corresponding to the number of fares or the like to be registered on the counter 107. The series of key plungers 93 actuate the rock-shaft 108 in a similar manner and through link mechanism (see Fig. 2) actuate the same counter 107 as is actuated by the series of keys 92. The series of plungers 92, 93 close electric circuits and set up combinations that will return a given amount of change from the coin deposited in or the currency registered by the machine. Assume, for example, that a fifty-cent piece is to be deposited in the machine and that it is desired to return forty-cents in change. The change to be made in returning fortycents from a half-dollar piece requires, in the particular structure shown, that the bars 56, 57 be raised to allow for the ejection of a ten-cent piece, a five-cent and a twentyfive cent piece. This is brought about in the manner now to be described. The appropriate key top 112 will be depressed to operate thecorresponding plunger 92,which plunger will be locked down in the manner hereinafter described. The fifty-cent piece deposited in the machine is calipered between the track 31 and the contact 29. The depression of the key 112 causes the lever 113 (see Fig. 6), pivoted at 114, to press down the bar 115, which is slidably mounted in the guides 116, 116, upon the back of the combination plate 52, this plate being apertured at 117, 118 (see Fig. 5), to receive the tongues 119 and 120 which project forwardly from the bar 115. The tongue 119 normally engages a slot 121 in a combination bar 122 and also a similar slot in the bar 125 which, at its left hand end, lies back of the bar 122. The tongue 120 normally lies in position to engage a slot 123 in a combination bar 124 and also a similar slot in the bar 126 which, at its left hand end, lies back of the bar 124. When the plunger 112 is depressed, the tongues 119, 120 are depressed, the tongue 119 disengaging itself from bars 122, 125 and the tongue 120 engaging slots 123 in bars 124 and 126, thus permitting bar 125 to be reciprocated in its channel in the plate 52 as will now be described.
Referring more particularly to Figs. 3, 5 and 18, the movement of the lever 2 in depositing the coin causes the rock-shaft 3 to thrust the down-turned end 22 of the lever 21 against a pressure bar 127, which is pivoted at 128, and whose rear end engages the top of the bar 23. The lower end of the bar 23 is connected to a bell-crank lever 129, pivoted in the lug 130 secured to the plate 52. The opposite end of the bell crank lever 129 is bifurcated and straddles a pin 131 secured to the locking bar 132, the bar 132 being held normally in the position shown in Fig. 5, by a spring 133. lVhen the bar 23 is depressed, the bar 132 is carried to the right until the notch 134 is engaged by the dog 135, thus locking the bar 132 in a position such that the pins 136 in the bars 55, 56, 57, 58, 59 may enter the notches 137 of the bar 132. Simultaneously with the shifting of the bar 132 and the movement of the tongue 119 in releasing the combination bar 125, the solenoid 138 is energized, drawing in its plunger 139 in the outer end of which is mounted a lever 140, the other end of the lever 140 being pivotally mounted upon the frame at 141. 011 said lever 140 is secured a clevis 142, which carries a vertically disposed pivoted bar 143, the upper end of which is connected to one end of a link 144, the opposite end of said link being connected to the combination bar 125 at 145. The lower end of the pivoted bar 143 has a similar link connection with the combination bar 126. Since said combination bar 126 is now locked by the tongue 120 against movement, the bar 125 is thrust to the left and its combination notches raise the studs 146, 147, 148, carried upon the bars 57, 56, 55, respectively, which in turn raise the rings 62, 61, 60, permitting one twenty-five cent piece, one five-cent piece and one tencent piece to be ejected from the machine by the ejector bars 81, upon the energization of the change ejecting magnets 77, in the manner hereinbefore described. In a like manner the solenoids 115', 161, 116, 138 and 161' and their coiiperating combination bars act to effect other change-making operations.
I will now describe the mechanism which controls the locking and releasing of the key plungers, reference being had more particularly to Fig. 7. Upon the end of the plate 94, on which the plungers 92, 93 are attached, I provide an inverted U-shaped bracket 149, Which serves as a mounting for the spring-pressed slide bolts 150, which are normally pressed against the plungers. Each bolt 150 is adapted to engage a slot the bolts 150 is provided with a downwardly extending guide pin 152, passing through slots 153 in the stationary plate 154. (See also Fig. 10). The cam-bar 155 is slidably secured to the plate 154 by means of screws 156, 156, passing through slots 157, 157 in the bar 155, and the bar 155 is actuated by an arm 158, (see Fig. 3), secured to the rod 40, and actuated by the link 39 in a way similar to the action already described in regard to the lever 41. This causes the cam surfaces 159 of the bar 155 to engage the pins 152, thus withdrawing the bolts 150 from the notches 151, allowing the springs 98 to return the plungers to their normal position.
Referring more particularly to Figs. 2, 3, Sand 9, inasmuch as the switching mechanism must be operated when any of the change-controlling solenoids 65, 115, 138, 161, 116, 138 and 161' are energized, I have mounted two rock- shafts 162, 163,carrying fingers 164, having depending pins 165, which will be engaged by the levers 140, causing either the shaft 162 or 163 to be rocked whenever any one of the solenoids 115, 138, 161, 138 and 161' are energized, thus causing the levers 168, (see also Fig. 9) to throw the switch 169 into engagement with the contact 170. The shaft 162 also is provided with a finger 164 (see Fig. 2) adapted to be engaged by the arm 72 of the bell-crank lever, which latter is actuated when the solenoid 65 is energized. In this manner also the shaft 162 is rocked to close the switch '169 when the solenoid 65 is energized.
The change ejector magnet 77, which, when energized, moves the plate 79, actuates a knife-switch 171, (see Fig. 14), and closes a circuit at 172 for the solenoid 37, which controls the movement to the track 31 to deposit the,coin in its appropriate tube and also causes the restoration of the depressed key.
The key 109 is an eliminating key and is used only in case a wrong key has been depressed, the depression of the key 109 releasing any key previously depressed.
The keys 110 and 111 are connected by means of levers 112, 113 to registers 114, 114, respectively, which register the number of one-dollar and two-dollar bills, respectively, from which change is 'taken, these being instances in which the money received does not enter the machine, but is retained by the operator. Said keys 110 and 111 operate switch springs controlling circuits which energize the solenoids 115,
'116, respectively. The solenoid 115 operates combination bars which return ninetyfive cents in change, and the solenold 116' operates combination bars which return onedollar and ninety-five cents in change. 151 in one of the plungers 92, 93. Each of The number of coins returned as change in one operation from any given magazine depends upon the height that the corresponding closure ring of the magazine is raised by its vertical bar, this in turn being determined by the contour of the cam-slot in the combination bar which lifts the vertical bar. The coin ejector 81 is raised with the bar in the foot of which it is mounted, and will eject one or more coins at a single operation, depending upon the height to which the vertical bar is raised.
The electric circuits which control the operations hereinbefore described will now be set forth, reference being had more particularly to Fig. 20. When a five-cent piece 1s lnserted and reaches its calipering contact 27 a circuit will then be closed .as follows: from one pole of battery B through conductor 200, switch arm 50, segment 51 conductor 201, track 31, the coin, contact 27, conductor 202, solenoid 37 conductor 203, to the opposite pole of the battery, thus energizing the solenoid, thereby actuating the registering mechanism, as heretofore described. The energization of the solenoid 37 causes the withdrawal of the track 31, allowing the coin to be deposited in its magazine. It also causes the switch arm 50 to be shifted in the manner hereinbefore described, moving said arm from the segment 51 to the segment 51". This opens the circuit of the solenoid 37 through the coin and closes an alternative circuit for said solenoid, said alternativecircuit being from one pole of the battery, through conductor 200, switch-arm 50, segment 51, conductors 212, 202, solenoid 37, and conductor 203 to the other pole of the battery. This alternative circuit is provided so that there will be no arcing between the calipering contact and the coin when said coin is dropped from the track 31. This circuit is established, regardless of the denomination of the coin which is inserted in the machine, for the reason that the solenoid 37 is, in every case, energized to drop the coin from the track 31 into its appropriate magazine tube. The circuit which is established by the introduction of a ten-cent piece where no plunger is depressed and consequently when change is returned, is as follows: from one pole of battery B, through conductor 200, switch arm 50, segment 51, conductor 201, track 31, the coin, coin contact 26, conductor 204, contact strip 96, the contact springs 97 on the plunger, conductor 207, solenoid 65, conductor 208, to the opposite pole of the battery, thus energizing the solenoid 65 which performs the function of shifting the combination bar 73, thereby raising the change-maker bar 56 and allowing for the ejection of five-cents in change
