CHANGE-MAKING AND COIN-DISPENSING MACHINE.

Specification of Letters Patent.

Patented June 1, 1915.

Application filed February 7, 1918. Serial No. 746,971.

To all whom it may concern:

Be it known that I, JAMES citizen of the United States, and a resident of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Change-Making and Coin- Dispensing Machines, of which the following is a specification.

My invention relates in general to change making machines and particularly to. that type embodying'means whereby the amount of a purchase will be automatically deducted from the sum rendered, and the correct change returned to the operator.

Among the main objects of my invention is the providing of dependable devices operating in such manner as to impose a minimum amount of work on the part of the operator, thereby eliminating errors to a great extent. Also to eliminate the faulty and incorrect operation of the machine, which errors cause the giving of short change when all of the coins 'in a tube have been exhausted. To this end Ihave embodied means in my machine for preventing the undue wear of the coin ejector bar, also for preventing undue friction .in the action of the latter.-

Also means whereby when a coin tube has been emptied the mechanism related to such tube will be automatically locked against further operation, thus preventing short change'being given. Also a coin guard preventing coins from being jarred outof the I discharge openings of the coin tubes by the operation of the coin ejecting devices of another ooin tube. Also means whereby the mechanism of the machine may be locked against operation. Other features will be more readily understood by the description of the operating parts and the operation of the several mechanisms of my machine as a whole.

' In the accompanying drawings constituting a part of this'specification: Figure 1 is A. PLOPPER, a

key has been depressed; Fig. 3 is a plan or top view of the mechanism shown in Fig. 2; in this view the deducting key, signal bell, most of the casing of the machine, and the delivery trough have been removed and the portions of the casing seen are shown in section; Fig. 4 is a fragmental front elevation of one of the coin tubes, illustrating the adjustable bandcovering the discharge opening of the coin tubes for the half-dollar, quarter-dollar, dimes and nickels; Figs. 5 and 6 are partial details of the devices provided for resetting a key erroneously operated; Fig. 7 shows on a larger scale a side elevation, with parts broken away, of that portion of the mechanism operating to eject half-dollars. In this view the ejector-bar is shown in its initial or normal position, and its position at a certain point in its forward travel, when operating to eject a coin, is also shown in broken lines; Fig. 8 is a perspective detail, on a larger scale, of the pawl provided for preventing an improper action of the ejector bar: Fig. 9 is a detailed side elevation of the rocker lever and adjacent parts of my machine; the full lines of this figure show the parts in their normal position, and the broken lines il ustrate the action of the cooperating parts: Fig. 10 is a top view of said rocker-lever illustrated in Fig. 9, showing, in addition, a portion of 14 is a fragmental side elevation of the mechanismprovided for ejecting coins from the dollar tube: this view details the operation of the parts by which one, two or three dollars mav be deducted from the amount tendered: Fig. 15 is a front elevation of the deducting keys shown in Fig. 14. looking at the latter as pointed by the arrow. and the bracket in which thev have their beara perspective view of my machine showing-Hing; Fig. 16 is a side elevation-of cooperatall the keys in their normal positions; Fig. 1 is a fragmental exterior view of the case showin the exterior parts of the means provided or locking the keys against operation; Fig. 2 is a vertical longitudinal section of my machine, with parts broken away, taken approximately on the line indicated by 2 in Fig. 1'; this viewshows the mechanism for ejecting hal'f dollars, and the broken lines show the positions assumed by the operating parts after the deducting ing. parts of the penny eiector mechanism Fig. 17 is a fragmental'front elevation of the deducting keys and certain adjacent 'parts shown in Fig. 16; Fig. 18 shows other details of construction of parts cooperating with the, devices shown in Fig. 16: Fig. 19 is a fragmental front elevation of the devices shown in Fig. 18:, Fig. 20 is a detail of I construction; Fig. 21 is a plan or'topmew. of a portion of the mechanism used mthe penny and nickel sections; Fig; a side elevation of a portion of the nickel tube, and the nickel ejector mechanism. This view shows in addition a means for preventing the coins from being jarred out of their respective tubes during the operation of the machine; and Fig. 23 is a plan or. top view of the parts shown in Fig. 22.

The mechanisms for actuating the different operating parts of my machine are divided into unit sections corresponding to the number of coin tubes in the machine. .Of these unit-sections, the mechanisms provided for the half-dollar, quarter-dollar, dimes and nickel tubes are all similar in details of constru ction and operation; therefore, in the description of these sections, I shall detail only the mechanism of the half-dollar section. But for the dollar and the penny sections different mechanisms are provided. Ordinarily penny change is not used, and for this reason the penny section is normally in an inoperative state, and is controlled by means whereby such mechanism may be readily thrown into operative position.

A series of coin tubes, a, b, c, are arranged in front of a casing. A,"as shown in Fig. 1. a desi nates the dollar-tube.-b the half-dollar tube, 1) the quarter-dollar tube. b the two dime-tubes. and b the nickel tube, and a the penny tube. In each of the similar sections. a frame member d extends laterally across the interior of the casing A and is removably attached to the latter by the screws e, as shown in Figs. 1 and 2. Said f ame member is formed with a lateral portion f containing a vertical slot f. in which bears the rear end of the ejector bar 9.. A carrier plate it (see Fig. 7)- is movably fastened on the frame member by. headed studs k, m, projecting respectively through the lon itud nal slot i'and the angular slot 7' of said carrier-plate. The plate It has a limited movement on the studs as shown in the broken lines of Fig. 2. A portion of'the carrier-plate h extends laterally so as to form bearings 'n; and the'lower end of the plate is formed with an ear 0. A rotatable stud-pin 7). .ec'centri'cally journaled (see (1 in Fi s. 7 and 20) in the carrier-plate 11, forms a bearing for the ejector bar 9, projecting through the slot 'v'of the stud-pin 1;. .By fa partial rotation of the stud-pin p the ejector-bar may be relatively raised or lowered. and thus adjusted to the thickness of coinsdeposited in the "related tube. A-coil spring r, connecting the ear. 0. to apin s on the frame nember d-normally holdsthe carv rierplate h as shown in Figs. 2 and 7. A stud-pin, t, projecting from the up er portion of the carrierlate h, pivotally connects the shank of the deductin keyry with' said carrier-plate. When the deducting'key is dep essed said carrier-plate will be depressed and rocked on the stud 7a to the position shown in the broken lines of Fig. .2. A

rangements of the other tubes. excepting the dollar and penny tubes, are substantially the same. Said half-dollar coin-tube is preferably made of some thin metal and its upper end is closed by a slotted cap 20, through which the half-dollars (indicated by 21 in Fig. 2) may be inserted. A plurality of vertically alined apertures 22, smaller than the coin, is provided in the front wall of the tube (see Fig. 1) to inform the operator of the approximatenumber of coins contained in the tube. The lower portion of the tube is further provided with an o ening 23, of

such a size that only one coin at a time may be ejected therethrough. I vAs it sometimes happens that coins. particularly dimes, wear very thin,'and the interior of the upper'edge of the opening 23 will wear round, unless made of particularly hard metal, I have provided an adjustable band attachment 24, shown in Figs. 1, 2 and 4, by which the said upper edge of the opening 23 will be maintained in good working condition. Such band attachment 24 is adjustablv held in I place by set-screws 26 inserted through the slot 25. ment 24 is specially hardened so as to hold a clearly defined edge.

The plate segments 27 constitute the base for all of the coin-tubes, said plate segments being spaced apart, as at 28, to permit the ejector bars g of the respective coin-tubesto act. "The lower portion of the back wall of the half-dollar tube 6 is provided with a, registering verticalslot 29 (see Figs. 2 and 3) to accommodate the arm 43 of the rockerlever 41 when the latter is rocked forward. As the ejector bar-g is'thrust forward, its plane of motion will carry it throu h the slots 28, 29, and theupwardly projecting.

nose as '(see Figs. 2 and 7) will impinge against a coin 21, thus ejecting such' coin from the tubethrough the opening 23. In such action the end'ofthe slot '0 will strike the bearing stud p of the carrier-plate h and a further movement of the ejector bar will cause said plate to be reset to its normal position. A covered trough, 30, serves as a receiver for all coins'thus ejected and delivers them through a conveniently sha ed spout (30), as shown in Figs. 1 and 2. This trough fits up snugly around the-coin tubes The lower edge of the band attach-' and prevents any coins from being taken'out j through the "opening 23except through the medium of the e ector mechanism.

- the operator not depressing the operating is offered to the automatic mechanism. An-

other objectionable feature heretofore existing in these devices was, the ejector bars did not receive their full forward throw andthe coins were, in consequence, only partially ejected. Such result was caused by key far enough. In such a case the automatic mechanism caused the ejector-bar to resume its normal position, and the coins were not ejected from the tube, but merely disarranged.

In my invention l have overcome the fault first referred to by causing the impinging face of the ejector-bar to be held away from' the lowermost coin when the bar is being returned to its normal position. The second objectionable feature I eliminate by providing devices which will prevent a partial forward throw of the ejector bar. To this end a pawl P (see Figs. 2, 7 and 8) is pivoted by a pin to the frame member (1. A stop-pin 35 limits the downward move ment of this pawl, and a coil-spring 36, fastened at its up-end to a pin 36' on the pawl, and at its lowerend to the frame member d, holds said pawl yieldingly on said stop-pin. The working end of the pawl P is formed with a lateral head havin a flange 38 provided with serrations 37. s the ejectorbar' is thrust forward, the pawl P will be lifted by the toe 39, and, upon the latter having passed the extremity of said pawl,

will resume its normal position on the stop pin 35. In the return movement of the ejector bar, said toe 39 will ride on the head I 40 of the pawl, causing the tilting of the ejector bar on the stud 72, and the movement of the nose a: of the ejector bar below the bottom of the coin tube, thus preventing the dragging of such nose w against the lowermost coin. If, however, the forward throw of the ejector'bar is not completed, the return movement of said bar will cause the bevel-edge 39 of the toe 39 to engage with the teeth 37 of the awl and lock the device from any further ackward motion. This would then indicate to the operator that the coin had not been ejected, and it would be necessary to again depress that particular operating key.

- I shall now detail the means whereby the ejecting mechanism is actuated. A fixed shaft y extends longitudinally the length of the machine (see Figs. 2 and 3) being mounted in the two ends of the casing A,

and the pay-lever 2 (see Figs. 2, 3, 12, 13 and 21) are fulcrumed on said shaft. As shown in Fig. 12, the pivoted end of said levers 2 is formed U-shaped, and with a supplemental short arm 5, to insure greater stability. The pay-lever 2 is actuated by the depression of its related pay-key 4 to which it is pivotally connected, as shown in Figs. 12 and 13. The portion 6 of the paylever 2 has fastened on it a bar 7, which overlies the portion 6 of theadjacent paylever to the right of it, as shown in Fig. 12, so that when one pay lever is depressed all pay levers to the right (that is, in the direction pointed by the arrow in Fig. 12) of the one actuated will also be operated. The pay levers on the opposite or left side of the one actuated will, however, not be depressed, because the portion 6 of the actuated pay lever would rock away from the bar 7 to the left of it.

Fulcrumed on the shaft y, adjacent to the arms 5 of the pay levers z are the individual coin-levers 8. See Figs. 2 and 12; and spacing sleeves 15 keep the coin-levers 8 in place. Such coin-levers are of bellcrank form (see Fig. 2) and have pivotally attached to the extremity of their arms 9 the shanks of the individual coin-keys 10. A rigid bar 11, shown only in Fig. 2, extends longitudinally the length of the machine. and forms a sop for the arms 12 of said individual coin lever 8. A coil-spring 14, connecting the arm 12 with a stud 14 on the frame-member d, normally holds the lever 8 in the position shown in Fig. 2. It will be seen from Figs. 2, 12 and 21 that the individual coin-levers 8 may be moved independently, by depressing the corresponding individual coin-keys 10; but the movement of an adjacent pay lever 2 will cause the adjacent individual coin lever 8 to be automatically, simultaneously actuated, by reason of the portion 6 of the pay lever bearing against the arm 12 of the lever 8.

Pivotally connected to the upper end of the lever arm 12 is a pitman rod 16. see Figs.

2 and 3. Said pitman rod is provided with a hook-shaped end 17, adapted to hook over a headed stud 18 projecting from the ejector bar g. A coil-spring 19, connecting the lever-arm 12 and a stud 19' mounted on the pitman-rod 16, holds the latter yieldingly to deduct a certain amount from the sum tendered will now be described. If the deducting-key, u, is depressed, the carrierplate It will be lowered to the position shown in the broken lines in Fig. 2; and when the ejector bar 9 is then moved forward, it will be guided by the stud-pin p to pass beneath the space 28 of the coin tube, instead of through such space, and the coin in such tube will not be ejected. Openings 31 are provided in the front face of the casing A (see Fig. 2) ermitting the ejector bar 9 a free forward movement when its line of travel is displaced from the horizontal, as mentioned.

A resetting bar 32 (see Figs. 2, 5 and 6) normally bears against the rear faces of the carrier-plate h. The bent ends or arms of this bar are pivotally mounted on the end members of the casing A, and one of these side arms is formed as a bell-crank 33, to which is attached the reset-key 34; see also Fig. 1. Therefore, when the deducting key u is actuated so as to lower the carrier-plate h, and the resetting bar 32 is correspondingly rocked, a depression of the reset-key 34 will move the resetting bar back into its normal position and cause all the carrier plates to resume their normal position. In this way an error may be easily and conveniently corrected.

In order to indicate to the operator when the number of coins in a tube has been reduced below a predetermined minimum, I have provided auxiliary signaling devices, as follows: A rocker lever 41, provided with upwardly projecting arms 43 and 46-, is pivotally mounted by a stud 41' on the frame member 03, see Figs. 2, 3, 9 and 10. A coil-spring 42, connecting said lever, and a stud 42 on said frame member, tends to rock this lever forward, but the toe w of the ejector bar acts as a stop, being engaged by the arm 46, therefore the rocker lever 41 will rock forward only when the ejector bar is thrust forward. The left end of the rocker lever 41 is bent, as shown at 44 in Figs'. 9 and 10, and a hammer 45 is pivotally attached to the rocker lever near said end. The arm 43 normally assumes the position shown in full lines in Fig. 2, and when operated by forward movement of the ejector bar bears against the coins in the coin tube through the slot 29; and when the number of such coins has been depleted below a predetermined number said arm will be allowed to 'lean still farther forward. When the rocker lever is rotated clockwise, as shown in the broken lines of Fig. 9, the upper end of the hammer 45 will be elevated to such a position that the forward travel of the ejector bar 9 will cause its stud 18 (shown in its different relative positions in broken lines in Fig. 9) to operate said hammer to strike a bell M on the frame member d. By

having bells of different pitches, for the mechanism of the different coin tubes, the operator will know at once which coin tube is depleted. As the ejector bar moves back to its normal position, the toe 10 will bear against the upwardly extending arm 46 of the rocker lever 41, and return the latter to its normal position. Another advantage of this device is that the tapping of the arm 43 of the rocker lever 41 against the coins in the tube will continually agitate the coins and jar any displaced ones back into place. If' any displaced coins should not be replaced by the action of the rocker lever, the deducting keys may be tapped gently and correspondingly actuating the rocker lever 41 for this purpose, when the ejector bar has been depressed and thrust forward.

Means for limiting the clockwise rotation of the rocker lever 41 are provided as follows: A three-armed lever C (see Figs. 2, 10 and 11) is mounted on a stud c in the frame member d. Said lever has a limited movement and is shown in its normal position in Fig. 2; when so positioned its bevel edge 57 will rest against the interior of the front wall of the casing A. An arm 58 of the lever C is arranged so that a small throw of the latter will cause said arm to contact with the laterally bent portion (1* of the frame member d; and a laterally extending arm 59 of the lever C is arranged so that when there is no coin in the tube, the rocker lever 41 will tilt to such degree as to bear on said arm 59. This action will so move the lever C as to bring the toe 59' on the lower end of the lever C directly under, and thus block the action of, the pay key 4. Normally said toe 59 will not interfere with the depression of the pay key 4. Such condit-ion will indicate to the operator that there are no more coins in that tube.

The ejecting and signaling devices used in connection with the dollar and penny tubes are similar to the devices previously described, except in the following particulars. The noses w of the ejector bars g are made longer, in order that they may eject more than one coin at once from the coin tube. In the dollar tube four dollars are normally ejected, and in the penny tube five pennies are normally ejected. I provide means, however, by which one, two or three dollars, and one, two, three or four pennies may be deducted from the amount tendered, and a corresponding lesser number of coins will be ejected. Hence change can be given in any sum from one cent to five dollars.

In the dollar division of my machine the carrier plate It is provided with a stepped opening 7", see-Figs. 14 and 15; and the stud m, fixed in a frame member corresponding to d, bears in such opening. Three deducting keys 47, 4S, and 49 are arranged so that their operation will cause the depresby the carrier sion of the carrier plate h one, two or three steps, for deducting one, two or three dollars, and causing the ejector bar g to eject three or two or one dollars from the tube.

As shown in Figs. 14 and 15, the dollar deducting keys bear in a slotted bracket 50 fastened to the interior of the case portion A. The lower ends of the shanks of the keys 47 and 48 are slotted to accommodate the depression of the carrier plate h by another key without operating either of such keys 47 or 48; and the lower end of the key 49 is curved, as shown in Fig. 14. Each of such key-bars has a stop pin as 51 located to properly limit the movement of said bars. A bar 53 is fulcrumed at one end on a pin 53' projecting on the interior of the case. The opposite end of the bar 53 is movably supported by a headed pin 55, projecting from the lug 52 of the carrier plate h and projecting through the slot 54 of the bar 53. The front end of the latter is made with a band segment 56 which encircles the opening 23 of the dollar coin tube a (see Figs. 1, 14). The lower inner edge of the band segment 56 is case-hardened, and in the normal position of the bar 53 such hardened edge is located alined with the top of the opening 23, as in Fig. 14. As now apparent, the movement of one of the dollar deducting bars, 47, 48 or 49 will position the band 56 as required for controlling the number of dollars ejected by the ejector bar 9'.

As stated before, the penny devices are normally disconnected from the rest of the mechanism. The penny carrier plate h is provided with a stepped opening j in which bears the stud m projecting from a frame member corresponding to d. See Figs. 16, 17 and 18. Said carrier plate h is shown as positioned when five pennies are deducted, as this is its normal position.

To bring the penny section of my machine into action, I provide a shift key 60, see Figs. 1, 16 and 18. A slotted link bar 61, fulcrumed on a stud 62 projecting from the interior of the casing A, is connected by its ends with the lower end of the shank of the shift key 60, and the carrier plate b and when the former is operated causes the latter to be raised. The position then assumed plate k is shown by broken lines in Fig. 16. It now will permit five pennies to be ejected from the tube. A bail 63, pivoted on an ear 64 on the interior of the front wall of the casing A (see Fig. 18) engages with a lug 65 on the shank of the shift key 60, and on the under side of the bar bears a projecting arm 66 of the deducting key u of the nickel tube of my machine, see Figs. 18 and 19. Consequently, when a shift key 60 is depressed. for throwing the penny ejecting devices into action, the nickel deducting key will also be depressed, thereby actuatmg the nickel deducting mechanism. It is to be noted that the latter may be actuated independently of the former. A bell crank 67, fulcrumed on a stud 68, projecting from the interior of the end wall of the casing A, has its lower end pivotally attached to the carrier plate k (see Figs. 16 and 17). A slot 67' in this lever permits the carrier plate b to be thrown into or out of operative position without affecting the penny deducting keys. Penny deducting keys, 69, 70, 71, 2, arranged to deduct one. two, three or four pennies, respectively, are connected to the upper end of the bell crank 67. A bracket 50', attached to the interior of the rear face of the case A, forms a hear ing for these deducting keys. Stop pins 51 limit the movement of said penny deducting keys in a manner similar to the parts detailed withrespect to the dollar section of my machine. Slots are provided in the lower ends of all said penny deducting keys, except 72, to permit the independent movement of the said keys. An auxiliary ear 73 on the carrier plate It (see Fig. 16) forms one bearing for the coin-restraining arm 74, the latter having a construction similar to the arm .53 shown in Fig. 14, and performing the same functions.

The nickel pay-lever z is made with two short arms 5, 5, instead of a long arm as 3. See Fig. 21. The penny pay-le 'erz is made with a curved arm 3 so as to position it alined with the nickel pay-key 4. The individual coin lever 8' is made longer than the lever of the other coin sections of my machine, and is actuated by the penny pay key 4". A lateral member 7', rigidly attached to the penny pay lever 2, extends to the left and bears against the portion 6 of the nickel pay lever 2 In this way when the nickel pay key 4 is depressed, both the penny and nickel pay levers will be actuated, but on account of the penny ejecting mechanism being normally positioned to deduct five pennies, only a nickel and no pennies will be ejected. When, however, the shift key 60 is depressed, the penny ejecting mechanism will be placed in operative position to eject five pennies, and the nickel ejecting devices will be arranged so as to deduct and not eject a nickel. A depression of the nickel pay key 4 will then cause five pennies to be ejected. but the latter could also be accomplished by depressing the penny pay key, which actuates the individual penny coin lever.

Oftentimes the vibrations of a machine will cause coins to be jarred out of the open ngs through which they are to be ejected. To prevent this action, I have provided an automatically actuated coin guard-bar R: see Figs. 22 and 23. Sa d bar R is pivotallv mounted on a stud'87. in the frame member d. and is made at its forward end with a finger 86, which normally will be projected in front of the opening 23, and thus bars the coins 21. A hole 90 in the frame and a slot 91 in the front face of the casing. A allows the guard bar R to be placed conveniently without interfering with any of the other mechanism. The length and weight of the material in the rear end of said bar are sufficient to hold the latter against a stop pin 88 on the frame member a when no coin is being ejected from the related tube, and a coil-spring 89, connecting said bar to a stud 89' on the frame member further aids in retaining said bar in this position. An inclined lug 92 projects laterally from the bar R, and the ejector bar 9 is provided with a-lateral toe 93, lying in the plane of action of the ejector bar, and slightly above the lug 92. When the ejector bar moves forward lts toe 93 will bear on the lug 92, thereby tilting the bar R, thus moving its finger 86 ofit of the way for the ejecting of a coin. When a coin has been partially ejected, as shown by the broken lines 21 in Fig. 22, the toe 93 will have passed the lug 92 and the action of the spring 89 will throw the front end of the arm R up; and as soon as the coin 21" has been completely ejected, the finger 86 will bar the next coin of the tube. While the ejector bar 9 is being returned to its normal position, it will swing away from the bottom of the coin tube, as previouslyexplained, and the toe 93 will pass beneath the lug 92 of the bar R. When the ejector bar has been lowered by reason of the deductin key being depressed, the toe 93 will pass orward under the wing 92 without affecting the guard bar R. In the event that the operator desires to leave the machine, a

locking device is provided which will pre-' vent unauthorized operation of the machine.

A pair of lugs, 75, 76 (see Fig. 2 are mounted on the floor of the casing for each coin section. A shaft 77 is journaled in the lugs and extends the len h of and through one end of the casing.

rovided with a head 78 (see Fi 1) whereby the shaft 77 may be rotate Arms 79 are firmly fixed on the shaft 7 7, and arms 80 are journaled in-the lugs 75. The rods 81 connect each pair of arms 78 and 80. By rotating the shaft 77, the arms 79 become so positioned under the shanks of the pay keys as to prevent the latter from being actuated, and the arms 80 become so ositioned under the shanks of the individua coin ke'ys 10 as to prevent them from being actuated. A simple form of, locking arrangement is shown in Fig. 2. A pawl 82 is normally held against a stop lug 83, by a spring 84. A lockin arm 85, rigid on the shaft 77, is engaged v thepawl 82 when the shaft 77 is rotated into contact with the stop lug 77. A key-hole K in the casin A (see Fig. 1') permits the insertion of a icy for engaging his end is.

the shank end of the pawl 82 for turning the latter and releasing the arm 85, so that the coil-spring 85' will act to return the shaft 76 and the locking bars 79 and 80 to their normal position, as shown 1D the full lines of Fig. 2.

I shall now explain the workin 's of my machine in actual operation. It 15 a well known fact that a coin of any denomination is equal in value to the total sum of the coins of lower denomination which are normally used in my machine. As an example, five dollars is e uivalent to the sum of four dollars, a halfollar,'a uarter-dollar, two dimes and a nickel, an if'de ired, five pennies could be substituted for the nickel. Likewise, one dollar is equal to the sum of a half-dollar, a quarter-dollar, two dimes and a nickel, or five pennies instead of the nickel. Therefore, by depressing any pay key corresponding to the amount of the coin tendered an e uivalent amount of change will be delivere from the machine. However, if the amount of a urchase is deducted from the aggregate change, the purchaser would be returned his true chan A specific example of the working of the machine is as follows: Let it be assumed that the amount of a purchase is forty-five cents, and the coin tendered in payment thereof is a dollar. The operator will drop the coin in the dollar tube, a. depress the deducting keys, u, for deducting forty-five cents, namely: the the two dime keys, and then depress the pay-key 4 of the dollar tube. A total of fifty-five cents would then be ejected from the half-dollar tube b and the nickel tube 1), through the delivery trough 30. In case a wrong deducting key u is depressed inadvertently, the reset key 34 is operated to return such deducting key to its normal position. If, however, the amount of a purchase is not a multiple of five cents, a portion of the change delivered will be in penny units, and for this reason it will be necessary to bring the penny mechanism into operative action. As an example, let it be assumed that the amount of a purchase is one dollar and eleven cents, and the coin tendered in payment thereof is five dollars. The shift key 60 is then depressed, which will throw the penny ejecting mechanism into operation, and simultaneously actuate the nickel deducting mechanism. The one dollar, one dime, and one penny deducting keys are then depressed, thereby deducting the amount of the purchase, and upon the actuating of the pay key marked five dollars, the aggregate change, amounting to three dollars and eighty-nine cents, will be delivered from the machine.
