The invention relates to coin changers.
As usually constructed coin changers operate on a dollar basis, that is, on the tender of one dollar the appropriate change of from one to ninety-nine cents will the delivered. In some instances special keys provide for returning change from a tender of fifty cents, seventy-five cents, or twenty-five cents. One object of the present invention is to provide mechanism having a shift bar for any tender that may be offered under a dollar by which the proper change due the purchaser is returned.
A further and important object of the invention is to provide a coin changer having mechanism for making change for any tender less than a dollar in which there is only one nickel compartment or stack having one ejector which does what would ordinarily be the work of three nickel compartments with their ejectors, thus keeping the width or size of the machine down to the limits used on the usual dollar tender machines.

7 Claims. (Cl. 133- 2) dollars.
Fig. 15 is a prospective view of the nickel ejector control mechanism.
Referring to Figs. 1 to 9, the machine includes a metal housing having a base [8, sides 19, and back 20. A coin tray 2| is suitably removably mounted at the front end of the housing and is formed to provide coin compartments or chutes for the various denominations of coins. The chutes A, B, and C carry pennies in stacks, the chute D carries nickels, the chutes E and F, dimes, the chute G quarters, and the chute H half The ejector mechanism for the chute A is adapted to eject one penny at a time therefrom, and the ejector mechanisms for the chutes B and C are adapted to eject two pennies each at a time, so that either one penny, two pennies, three pennies, or four pennies can be dispensed from the machine as needed for change. The
- ejector mechanism for the chutes E and F are each adapted to eject one dime at a time while the ejectors for chutes D, G, and H are adapted to eject one coin at a time from each of said chutes.
A keyboard 22 is mounted on the top of the housing in back of the tray and carries change keys 23 numbered from 1 to 99 and special change keys 24 for 10, 25, 50 cents and one dollar and a lock release key 25. The keys 23 are similar to those of the prior U. S. Patent No. 1,850,- 198, of March 22, 1932, to Edward J. Brandt, and are mounted to slide in the keyboard, being pushed downwardly by the operator against the action of a return spring 25 some of which are shown, and each key having a rocker or rockers actuating finger 2'! formed integral therewith or secured thereto and engageable with one or more rockers 28 having arms 29 pivotally mounted on pivots 30 mounted in the sides of the frame. Each rocker 28 carries an arm 3i, some of which are shown in Fig. 2, pivotally connected by a pin 32 to the outer end of a suitably guided pusher bar or ejector operating member 33 or the members 331, 330, or 335 hereinafter referred to. Each of the pusher bars is pivotally or thrust connected at its outer end to an ejector carrying slide or plate 34 which is slotted at 35 and 35 to receive guide rollers 31 and 38 carried by frame upri hts 39 and 40, said plates 34 being similar to the plates 23 of the aforementioned patent. The ejectors each include a coin ejector finger 4i pivotally connected to its slide 34 by a pin 52 and having a second finger 43 pivotally connected to it intermediate its ends by a pin 44 which fingers are yieldingly urged apart by a spring 45 interposed between them and mounted to operate a swingable lock release on a guide bolt 46. The slides 34 with their pusher bars 33 are spring returned in known manner to bring the ejector fingers to an inoperative position, the slide 34 for the nickel ejector, however, having a return spring 34a.
The above construction operates in known manner. The depression of any one of the keys 23 actin through the rockers 28, and pusher bars 33 and slides 34 move the fingers 4i and 43 through the lower slot 47 in the coin tray to eject one or more coins from the coin chutes. As in the aforementioned patent a coin engaging finger or lever 48 is pivotally mounted at its upper end 49 to work in an upper slot 50 in each chute of the tray. Each finger 38 is yieldingly held against the stack of coins by a bell crank locking lever i pivotally mounted on a transversely extending shaft 52 and urged by the greater weight of its roller carrying end 53 into engagement with said finger. During each reciprocation of its associated slide 34 the roller rides on the top of a stop projection 55 on said slide when the finger 48 is in the position shown in Fig. 2. When, however, the coins C in the coin chute becomes depleted to three or less, then the finger 53 is free to swing outwardly, and the roller end 53 of the lever 5| drops downwardly into the path of movement of the stop projection 54 and thus prevents movement of the slide 34 and its ejector fingers to eject a coin.
The operation of the parts of the machine thus far described is the same as that of the aforementioned patent for delivering change of any amount from 1 to 99 cents on receipt of a tender of one dollar by the operation of the proper key 23 whose numbers represent the amount of the purchase price. For example, if a dollar is given for a one cent purchase, depression of the key 23 numbered 1 will through its finger 2'! actuate the rockers 28, bars 33 to simultaneously move the slides 34 carrying the ejector fingers for the chutes H, G, F, E, C, and B to deliver 50, 25, 10, 23, and 2 respectively, or 99 change. The special change keys 24 each have fingers to operate the ejectors which will deliver the amounts appearing on these fingers in the form of loose change in the same amount as received. The lock release key 25 is adapted in known manner bar 55 pivoted at 55a at the sides of the housing and movable upwardly to engage the locking levers 5! to move them out of the path of their slides 34 so as to permit dispensing one or more of the last three coins in a tray whose coins have become depleted to the extent that the finger 48 has swung outwardly into the tray.
As in said prior patent special keys 56 and 5] are provided to take care of tenders of 50 for the key 55 and either 25 or 75 for the key 51. These keys act as ejector cut-out or incapacitating keys and are shown in Fig. 4 slidably mounted in a plate 58 and normally urged upwardly by springs 59. The key 55 has a shank 69 carrying a pin 6! adapted to engage a projection 62 on a U-shaped frame 63 whose legs are pivoted at 64. Depression of key 56 causes pin 6! to swing frame 63 downwardly and thus depress the ejector finger 4| for the 50 piece stack downwardly so as to prevent feed of coins therefrom when a tender of fifty cents is received. This frame has cut outs 56, 6?, and 58 to clear the ejector fingers for the chutes G, F, and E (25, 10, and 10), respectively. The key 51 has a shank 59 V carrying a pin 10 adapted to engage a projection H on a U-shaped frame 72 whose legs are also pivoted at 64. The projection ll extends over the frame 63, so that depression of the key 51 causes pin ill to swing frame '12 downwardly and with it the frame 53 and thus depress the ejector fingers 46 for the 50 stack and 25 stack downwardly so as to prevent feed of coins therefrom when a tender of either twenty-five cents or so enty-five cents is received. The frame 12 has cut-outs i3 and l i to clear the ejector fingers for the chutes E and F for the dimes.
With this construction when a tender of fifty cents for a purcase less than fifty cents is received, the operator presses down the key 56 to prevent ejection of a coin from that chute taking place when she depresses one of the regular keys representing the amount of the purchase to deliver the change to the purchaser. Similarly, when tenders of 75 or 25 are received for purchases less than either of these amounts, the key 51 is depressed so as to prevent ejection of coins from either the 50- or the 25 chutes.
The present invention includes the above keys 5? and 56 and keys l5 and it which take care of operating the machine to give change for any tender less than a dollar of an amount ending in five or zero, that is, five cents or ten cents, or any multiple of these not including 25, 50, and 75 cents. The key '55 numeralled 5 is slidably mounted in the plate 58 and urged upwardly by a spring l7, and the key i6 is similarly mounted. The shanks 78 of each of these keys carry pins 19 adapted to engage one of the projections 80 of a third LJ-shaped frame Bl pivoted at 64, the projections 86 extending over the frames 63 and 72 so that depression of either key 15 or 7 acts to depress all the frames 63, i2, and BI.
During any one change making operation each of the keys 55, El, l5, and 16 is temporarily locked when depressed by engagement of a swinging latch member 82 with a downwardly tapered projection 83 on each key, the member 82 being U-shaped and pivotally mounted at its ends 82a on a bracket 85 secured to the base of the machine and yieldingly urged to a looking position by a spring 85. Aftereach operation any one of the locked keys 56, 51, T5, and i6 is released by means that move the latch 82 to a release position against the action of its spring comprising cam projections 86 engaged by a U-s'haped lock release bar 87 pivotally mounted in the sides of the machine and adapted to be engaged by the front end 88 of any one of the slides 34 and be swung thereby into engagement with said projections 85 so as to swing the latch 82 clockwise as viewed in Fig. 2 to release it from any of the locked special keys as the slide 34 completes its ejection movement when its controlling change key is depressed.
In order to make change on a basis of a tender of any amount less than a dollar the keys must be capable of moving the nickel ejector for any amount tendered to and including ninety-five cents. Because of this the usual operation of the nickel ejector for a dollar tender is not sufficient, out the nickel ejector must be capable of operation when any of the regular keys from 1 to 95, inclusive, are depressed though in some instances the nickel ejector is not actually operated. To render the nickel ejector effective for operation from the keys 1 to each of these keys has a finger which when the key is depressed will either act upon the ordinary nickel rocker or supplemental rockers. Referring to Figs. 2 and 3, the rocker 2% for operating the nickel ejector on a dollar basis is connected to the pusher bar 331. In addition a rocker 280 for operating the nickel ejector, on a tender of less than one dollar of ten cents or a multiple thereof excluding fifty cents, is connected to a pusher bar 330 and a rocker 285 for operating the nickel ejector, on a tender of less than a dollar of five cents or a multiple of five excluding twenty-five and seventy-five cents is connected to a pusher bar 335. Each of the pusher bars 331, 33B, and 335 is adapted to be brought into and out of operative position with a pin 38 on the slide 34 for the ejectors associated with the nickel compartment shown in Fig. 2, each bar having a notched pin engaging end 99 which in the raised position of the bar engages said pin 89 and in the lowered position of the bar clears said pin. Since in connection with tenders less than one dollar the ordinary or regular pusher 331' cannot be used, this bar is dropped down when either of the pusher bars 33% or 335 is to be operated, and as a consequence the means for raising and lowering the pusher bars 33, 335i, and 335 are controlled by mechanism associated with the special keys 1% and '13 which are the 5 and special keys on the keyboard.
Referring to Figs. 2 to 7, the key i is provided with a wedge, a cam projection 51 similar to the projection 94 on the key 13 which on the depression of the key engages a roller 92 on a push bar 93 to move said bar inwardly as viewed in Fig. 3. The key 76 is similarly provided with a cam projection 94 which on the depression of the key engages a roller 94a, on a push bar 95 to move said bar inwardly. A pivot shaft 96 is mounted on fixed uprights 96a, and a second shaft 9'! is pivotally mounted in said uprights and forms a part of swinging frame 93 which has spaced arms 93 and IDES and an arm Hll. A raising and lowering lever or finger W2 for the bar 337 is pivotally mounted on the shaft 96 and has a pin and slot connection 1132a with the arm I31. A U-shaped frame member [63 is pivotally mounted on the shaft 35 and has a finger projection I04 for raising and lowering the bar 3313 and an arm m5 which extends up between the rear end 55a of the push bar as and the arm 99 of the frame 98. A U-shaped frame member N is also pivotally mounted on the shaft 96 and has a finger projection It! for raising and lowering the bar 335 and an arm I08 which extends up between the rear end 9311 of the push bar $3 and the arm 100 of the frame 98. The frames 98, lGS, and 306 are each biased to a position in which the finger m2 is in a raised position and the fingers Hi4 and I0! are in a lowered position by tension springs H39, Hi], and Ill, respectively, connected to said frames and to the housing, and Figs. 5 and 8 show the regular pusher bar 331 engaged with the pin 89 for operation of the machine on a dollar tender basis. If now the tender is less than a dollar in any amount except 50 ending in zero, the operator presses down on the 0 key or key 16, and this we have seen depresses all three of the frames 53, '12, and 8!, thus cutting out the.
ejectors for 50, 25, 10, and 10;? and at the same time moving the push bar 95 inwardly causing it to engage the arm I65 and by it swing the frame SE3 counterclockwise and thus swing finger 54 so as to raise the bar 33% to bring its notched bifurcated end 336a into engagement with the pin 89. At the same time since the arm Hi5 abuts the arm 99, the frame 98 swings or turns with its pivot shaft 81 in the same direction and swings arm 10! upwardly which through the pin and slot connection 102a causes the lever 102 to swing down so that bar 331' is lowered to an inoperative position while the bar 33!: becomes effective to operate the slide 34 for the nickel ejector. If the tender is less than a dollar in any amount except 25 and ending in five, the operator presses down on the 5 key or key l5, and this similarly depresses all three of the frames 63, 12, and Si, thus cutting out the ejectors for 50, 25, 10, and 10 and at the same time moving the push bar 93 inwardly causing it to engage the arm I08 and by it swing the frame 156 counterclockwise and thus swing the finger ill? upwardly so as to raise the bar 335 to bring its notched end 335a into engagement with the pin 89. Since the arm I00 abuts the arm I33, under these conditions the frame 98 swings with the frame I05 causing the arm llil to swing the finger Hi2 down in the same way as described in connection with the push bar 95. Thus the slide 34 for the nickel ejector has three push bars 331', 330, and 335 selectively available for operating it so that if the rocker associated with the push bar is then in an operative position relative to the slide, the slide will be operated to eject a nickel from the nickel stack.
As examples of the method of operation of the above described structure, assume the purchase price of an article to be 65c. When the purchaser tenders a dollar for this article, it is only necessary for the operator to press downwardly on the key, and this will act through its fingers to move the ejectors for the chutes F and G to eject a 10 piece and 25 piece, respectively. .11? now the tender for this 65 article is 75, then the operator first presses down on the special key 5'! numeralled 25, '75 in Fig. 1 of the drawings. This operation incapacitates the ejectors for the chutes H and G and the ejector for the chute E is operative as before to eject 10. If the tender is 70, which is a number ending in zero or one of the multiples of ten, the operator first presses down on the key 76 which is the zero key, thus incapacitating the ejectors for the chutes H, F, G and E and at the same time in doing this operates the pusher bar which as previously explained acts through the frame 99 to move the finger 5&2 down so that the connection from the regular nickel push bar is shifted to the 330 push bar and then on pushing down the 65 button, the ejector for the chute D is operated and 5c in change is delivered.
The key 65 for the dollar tender does not have any element 27 to operate the rocker 2dr, but it does have an element 21 to operate the rocker 285) so that the depression of the special key 76 puts the machine in a condition where the depression of key 55 can operate the nickel ejector bar push bar 339. It is also to be noted that some of the keys are provided with one ormore elements 2? to selectively cooperate with the rockers 2823231 and Assuming the purchase price to be 32 and the tender a dollar, pressing down on the 32 key operates the ejectors for the penny chute A, the two penny chute C, the nickel chute D, the first 16 chute E, and the 50 chute H whereby 68 in change is delivered to the purchaser. Now-if the tender is 50 for this purchase, the operator first presses down on the key 55, thus incapacitating the 50 ejector and then on depressing the 32 key the ejectors for the chutes A, C, D, and E, one penny, two penny, 5c, and 10, respectively,
. are operated dispensing the 18 change. In each of these two transactions the nickel ejector operates in the normal manner. If for the 32 purchase, 40 is tendered, then the zero key 75 is first depressed incapacitating the ejectors of the chutes E, F, G, and H, and at the same time -shifting the drive from the pusher bar 337 to the pusher bar 330, and then when the 32 key is depressed since the key 32 also has a finger '27 which will operate the bar 330, the ejectors for the chutes A, C, and D will be operated to elect 8;? change. If for this same purchase price the amount tendered is 35, then the key l or the 5 key is depressed which incapacitates the chutes E, F, G, and H and atthe same time acts on the pusher bar 93 to shift the drive from the pusher bar 331' to the pusher bar 335, and then when the key 32 is depressed, the ejectors for the 193 chute A and the two penny chute C are oper- 'ated to deliver three cents and the operation of the push bar 93 in shiitingthe drive from the bar 33r to the bar 335 has rendered the regular nickel ejector ineffective, also the rocker 285 which Operates the bar 335 is then not actuated since there is no finger 2'! on the key 32 for opere ating rocker 235.
The machine shown in Figs. to is similar to the first described form except that the coin tray H is arranged at the back of the machine and the keyboard 22 is in front 01 it, and the special keys are adjacent the front side of the machine. This arrangement involves certain changes in some of the parts previously described. Similar parts have been similarly designated.
Referring to Fig. 10, the change keys 23 with their rocker actuating fingers 2'! engage the rockers 28 which have arms 29 pivotally mounted on pivots mounted in the sides of the frame of the machine carry arms 3| pivotally connected by pins 32 to pusher bars 33. Each pusher bar is pivotally connected by a pin 33a to an ejector lever I I2 pivotally mounted on a transversely extending shaft III3 and having an ejector finger I I4 pivotally mounted thereon at I I5 which ejector works through the slot 47 of the coin tray and is yieldingly urged upwardly by a spring I I 6. Unly the ejector for the nickel tray is shown in full in side elevation, but the other ejector levers I I2 and their pusher bars 33 are shown in Fig. 11.
Each lever H2 is urged to a retracted positionbyaspringrl I1.
The coin depletion lever 48 and its associated bell crank lever 5| are shown in Fig. 10 and act in the same way to stop the operation of the machine. Normally a roller -I I8 on the upper end of the lever H2 passes under the lever 5|, but when on coin depletion the lever 48 swings out into the coin chute or compartment, the outer end of the lever 5| swings downwardly into the path of movement of the lever I I2 and strikes spring 12d. 1
Referring to Fig. 10, a bracket I25 mounted on the base of the machine and provided with arms I25a has the lower ends of the shanks of keys I I9 to I22 slidably mounted therein and carries a pivot shaft I26 on which levers 9a. I2.0a,
. s Jo I2Ia, and I221: are pivotally mounted, each of said levers having a cam surface I21 adapted to be engaged by the lower end of the associated key so that when said key is depressed, this lever will. be rocked clockwise as viewed in Fig. 10. The shanks of the keys H9 and I22 are each bifurcated and each bifurcation acts on its associated lever so that there are two levers II So for the key IIS and two levers I22a for the key I22. With th exception of one of the levers I22a, each of the levers N90. to I22a is pivotally connected at I28 to a pull bar or link. In Fig. 11 these links are designated H92), H90, I280, I2Ib, and 122i). The inner lever I22a is directly connected to the inner lever I I9a by a tie bar I220.
Referring to Fig. 12, the ejector fingers II4 (starting from the left) are for the fifty cent coin stack, the twenty-five cent stack, and the two dime stacks, respectively, and a throw out member I29 is associated with the fifty cent ejector finger, a throw out member I30 is associated with the twenty-five cent finger, and a throw out member I3I is associated with the two ten cent ejector fingers. The member I! is shown in side elevation in Fig. 10. A bell crank lever is operatively connected to each of the throw out members and its operating link, and each of these levers is pivotally mounted on hollow spacer sleeves I 32 mounted on the pivot shaft I I3 for the ejector levers H2. The throw out member I29 is guided at its top by a 'pin I33 working in a slot thereof and is pivotally connected at its lower end by a pin 3 3 to an upstanding ear on one arm I35 of the bell crank lever I35 whose other arm is pivotally connected by a pin I 3'! to the end of the pull bar I 2Ib. Thus movement of bar or link I2 I22 by depressing the 50 key I 2I will move the member I29 downwardly and with it the ejector finger to incapacitate it. The throw out member I36 is guided at its top in the same way as the member I29 and is pivotally connected at its lower end by a pin I38 to an upstanding ear on one arm I 33 of the bell crank lever Ill whose other arm is pivotally connected by a pin I4I to the end of the pull bar I20b. As this pull bar is operated by the 25, 75 key the arm I33 has a projection I39a that extends over the arm I35 so that depression of the key I2I will through movement of the bar I231) by the lever I 20a swing the lever I 49 soas to pull down on the member I30 and also by engagement of the arm I38a with the arm I35 move the lever I36 so as to pull down on the member I 28 so that both 56 and 25 ejectors are rendered inoperative. The throw out member I3I is guided like the others above described and is pivotally connected at its lower end by pin I42 to an upstanding ear on one arm I43 of the bell crank lever I44 whose other arm is pivotally connected by a pin I as to the end of the pull bar or link H which due to th tie bar I220 may be operated by depressing either the key H9 or the key I22. The arm I43 of the bell crank I44 has a projection 13a that extends over the arm I39 with the result that when either the key H9 or I22 is depressed, the pull bar or link H90 acting on the lever Md pulls down on the throw out member I 3i to render the two dime ejectors inoperative and at the same time since projections I43@ and I39a connect the bell cranks I 46 and I39 for movement with the bell crank I44, the members I SI and I29 are also pulled down to throw out th quarter and fifty cent ejectors. It will be noted from the above that this arrangement performs the same function as 9 the key controlled frames 63, In and 85 of the first described construction.
As in the first construction, the nickel ejector is adapted to be operated by either one of three separate key-controlled rockers whose connections with the nickel ejector lever are controlled by the operations of the keys iii; and H2 and their pull bars or links 15% and A push bar 331cc connected to the rocker 237 has a forked end engage-able with a pin Hit on the ejector lever I I2 for the nickel compartment. The rocker 288 is pivotally connected to one of the push bar 333m whose forked end H ll may engage the pin ME. The rocker pivotaliy connected. to one end of the push bar 335m whose forked end 548 may engage the pin I46. For selectively controlling the positioning of the push bars 331m, 336m, and 335m by the keys H8 and 122 which correspond to the 5 key and zero key of the first construction the mechanism best shown in Fig. is used. This mechanism includes a. base frame Hit having upstanding ears 58 for a pivot shaft ME and having upstanding ears 152 for a pivot shaft he shaft I54 has U-shaped frames and E55 pivotally mounted thereon, both of which nor mally moved to the position shown in Fig. 15 by a spring I55 acting on a lever 5'] which carries a pin i58 that engages one of the arms of each frame i5 5, i535. The other arm of the frame is pivotally connected at 59 with the pull bar or link ilsb. The other arm of the frame I55 is pivotally connected at filial with the pull link 1222;. An elevating finger it! for the bar 335m forms one arm of a bell crank lever it?! pivoted on the shaft I53 and operativeiy connected by a link I53 with one arm of the frame An elevating finger 164 for the bar 3351a forms one arm of bell crank lever 155 pivoted on the shaft [53 and operatively connected by a link its with one of the frame l55. An elevating finger i6? for the bar 33rm forms one arm of a plain lever 6&8 pivoted on the shaft :53 and operatively connected at IE9 to one arm of the lever l5? which is a bell crank lever. From Fig. 15 it will be noted that the a'rangement of these levers is such that when the finger i6? is up so that the regular nickel pusher strip is operating, the fingers it! and let are down and the push bars 33fim and 335m are in inoperative position. When, however, the frame is ti. ted counter clockwise by the depression of the key i is acting through th link H927, the finger iili is raised while simultaneously the lever i5; turns to swing the lever 553 clockwise and depress the finger I61. Similarly, when the frame i55- is tilted counterclockwise by the depression of the key 1'22 acting through the link i227), the finger 56s is raised while simultaneously the lever 35'? turns to swing the lever I98 clockwise and depress the finger 167. Thus the selective keys HS and E22 act to control which of the pusher bars are positioned to actuate the nickel ejector lever.
As the first described construction the keys H9, 526, 12!, and i22 are adapted to be locked in by the engagement of a latch member Elli, similar to th member 32, pivoted at ill and normally urged. to a locking position by a spring l 72, each of the keys having one or more projections H3 engageable with said latch. After each paying operation under the control of any one or more of the keys above mentioned, the latch is released on the return of any one of the operated change keys 23 by a connection of a change key operated U-shaped release bar H4 pivoted 10 on the base of the machine and shown in Fig. 11 as projecting over the free end of a release lever H6 pivoted at Ill on one of the arms i25a and having a latch throw out cam surface H8 engageable with an arm of the latch to shift said latch out of locking position when said free end of th lever H6 is tilted downwardly by the depression of the bar fill by any of the rockers 28 for any of the change keys 23. The lever H6 ireturned by a spring 119.
The method of operation of the modified forn is the same as the first form. The modified form is preferred because the ejector operating means is simpler and the coin tray is above the keyboard. In this connection, the coins are ejected by the ejectors into a trough 18 3 which has a side outlet I34.
In each instance while two additional rockers for operating the nickel ejector mechanism have been added to the changer of the patent previously referred to, this does not act to increase the length of the machine and its width stays the same since the one nickel tray with th ejector link shifting mechanism above described takes care of what would ordinarily be taken care of by three separate ejectors and trays.
It will be noted that by the hold down mechanism controlled by the keys l5, l, 55, and i6 in the first form and H9, I26, i2 l, and H2 in the second form any key in the keyboard will deliver from every possible tender, these keys cting as previously noted to render one or more the ejectors inoperative.
I desire it to be understood that this invention i. is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
What I claim as my invention is:
1.
