AUTOMATIC CHANGE-MAKER.

Application filed March 9,1909, Serial No. 482,222.

T all whom it may concern:

Be it known that I, GEORGE W. HOLLINGS- won'rrr, a citizen of the United States, re-

"tional or unintentional, in its operation, as

well as to improve the construction of the various parts and their mechanical arrangement with relation to each other.

The invention consists in the combination with a cash drawer, of a coin tube or magazinc and coin ejecting mechanism therefor, accessible for removal of the coins only from the interior of the drawer.

The invention also consists in the construction and arrangement of parts of the coin receiving and ejecting mechanism, as well as the peculiar arrangement of their combination with the operative mechanism of a cash registering device as will hereinafter he more fully set forth and claimed.

The invention also consists of coin ejecting mechanism adapted to cooperate with a plurality of coin holders to eject coins from the different holders in succession to empty one after another.

be ejected. Fig. 6 is a detail perspective view of one of the slides and part of the operative mechanism'therefor. Fig. 7 is a similar view, illustrating the arrangement of the double slide and operative mechanism therefor. Fig. 8 is a general perspective view of parts of my improved change making apparatus and parts of a cash register and the mechanism for transmitting the operation of the cash register to the change making apparatus. Fig. 9 is a partial cross section on a line corresponding to the line 2 of Fig. 8, more clearly illustrating the arrangement of the key locking device. Fig. 10 is a vertical section on a line extending from the front to the .rear through the coin tubes, illustrating the construction of my improved device with a slide having two coin receiving openings. Fig. 11 is a similar view, illustrating the construction of the device with a slide adapted to eject coins from either of the coin tubes, but constructed and-operating differently than the slide illustrated in the previously described figures.

As illustrated, my improved change making apparatus is installed in the cash drawer 1 of a cash register of well known construction, having the keys 2 on key bars 3, which, when the keys are depressed, serve to register various amounts and also, ordinarily, serve to release the cash drawer and allow it to open for the insertion or removal'of the cash either in the form of coins or paper, but, with the use of my change maker, does not thus automatically open. A bar 4 which extends transversely of the cash register, and, as shown, is mounted on the shaft 4 forming part of the cash registering mechanism, carries the fulcrums 5 common to the selectors 6, 63.6", 6, 6, and 6, and the ejecting mechanism operating trips or fingers 7, 7, 7", 7, 7, and 7, as well as the key locking finger 8.

. A shaft 9 extends transversely of the apparatus, and, as here shown, is journaled in plates 10 and 10, at the sides of the apparatus. These plates 10 and 10 flank the block 11 which contains the current coin tubes or magazines 12, 12 12 and 12, and the auxiliary coin tubes or magazines 13, 13, 13 and 13, designed for receiving nickels, dimes. quarters and half-dollars. respec tively. The current and auxiliary com the surface of the block 11 whic tubes comprise a housing for the coins. .As shown, the shaft 9 passes transversely of the apparatus, as above referred to, and lies approximately over the centers of the current tubes or magazines and below the lan'e of 1s mclined rearwardly in the region of the current coin tubes. Rotatably mounted on the shaft 9 over the current tubes or magazines 12, 12", 12 and 12 are the rotatable sections 14, 14*,14 and 14, respectively, which 1n the aggregate occupy the entire length of the shaft-.9 between its hearings in the plates 10 and 10 and are heldagamst lateral movement thereby. As herein shown, each section has two members extending above the shaft 9 and each member is bifurcated to receive the end of one arm 15 ofa slide operating bell crank 16, this arm being pivoted therein on a pin 17 which thus forms a fulcrum for the bell crank. Each section on the, shaft 9 also has a downwardly extendingarm 14 which is adapted to be en aged by coins inserted in the current tu e to rotate the section on the shaft.

Each of the bell cranks 16 has two other arms 18 and 19, the arm 18 being short, as is the arm 15, and being adapted to be engaged by the lower end of its corresponding trip or finger 7, 7*, 7", 7, 7, or 7, as the case may be, one of said bell cranks being provided for each trip or finger. The arms 19, as shown, extending into slots 19' in the block 11, are much longer, in order that they may increase the movement of the trip or finger sufliciently to provide the proper amount of movement for the ejector slides 20, to which they are connected by means of links 21 pivoted to their free ends and to upwardly extending lugs 22 on the sides of the ejector slides. These ejector slides are pulled back by springs 20'.

As is described in my former patent, the ejector slide to be operated is selected by means of one of the selectors, which transmits the motion of the key bar 3 to the trip or finger 7, a particular selector being depressed by a particular key only if it has an upward projection under said key and a particular selector depressing its particular trip or finger through its means for engaging with said trip or finger. hen a selector is thus depressed and depresses the trip or finger, the lower end of the trip or finger is carried forward so'that it is over the part of the arm 18 with which it is adapted to engage, and then, upon the further depression of the key bar, coming into contact with the transverse bar fulcrum 5 of the trip or finger is depressed, causing the trip or finger to move downward bodily and to depress the arm 18 and draw the lower end of the arm 19 of the bell crank forward, bringing the ejector slide 20 with it.

The foregoing description of parts being references in 4, and depressing it, the

equally applicable to the device embodied in my former patent, hereinbefore mentioned, is only given for the purpose of facilitating the following description, which has to do with marked improvements, that, in combination with the above-,described parts, accomplish the object of the present invention. It may also be well understood from my previous patent that the bell cranks 16 reachof the. trips or fingers 7 by rotating the sections, as the section 14, in which the bell cranks are eccentrically fulcrumed, this rotation taking place every time a coin is inserted into one of the current coin tubes or magazines, due to the engagement of the edge of the coin with the downwardly proectlng arm of the section over the tube. This feature vent the ejection of a coin of the same denomination as that inserted, or of larger denomination, but not to operate the sections over the tubes receiving coins of lower denomination, and the manner of operation of this feature as it goesto accomplish the obect of making change is fully and clearly set forth in myprevious patent above referred to. It will thus be seen that the section over the half-dollar tube will be operated upon the operation of any of the other sections. It will also be observed that it is desirable to prevent the registering of a sale without the insertion of a coin into the cash drawer. This is insured by providing a key locking bar 23 having a slot 24 through which a pin 25, mounted in the side plate 10, projects. This bar 23 is fulcrumed in the member of the section 14 adjacent to the plate 10 and is thus drawn forward when the section is rotated, as hereinbefore described, and this section being rotated every time any of the sections are rotated, the bar will be drawn forward every time a coin is inserted into any of the coin tubes. This bar 23 is provided with means for engaging with the lower end of the trip or finger 8, and as this trip is fulcrumed on the transverse bar 4 which must be depressed if the keys are operated, it will be seen that when the bar 23 is in its rearward position and the'lower end of the trip 8 engages with it, the keys cannot be operated. However, when a coin is inserted into any of the current coin tubes, the bar will be drawn forward out of the way of the trip 8 and allow the bar to be depressed, the amount of the sale registered, and the ejector slide operating mechanism to be operated in the manner described.

The plate 26, mounted, as usual, over the forward part of the cash drawer, on the cash register, is provided with an opening 27 which may be merely wide enough and long enough to allow access to the current coin tubes or magazines thereunder. As will be may be drawn forward out of is primarily intended to prebecome exhausted, when this is the case, a the raised noted, the entire coin receiving and coin ejecting mechanism is mounted below the upper edges, of the sides of the drawer allowing the drawer to be closed, and thus the cashcontained therein, as well as the means for ejecting it therefrom, is entirely concealed. A plate 28 is mounted over the shaft 9 and the sections mounted thereon, and 0bstructs the entrance to the current coin tubes excepting through slots 29 left between the forward edge of said plate and the upper sloping side of the block in which the coin tubes are contained. Thus, to insert a coin it is necessary for it to engage its edge with the arm on the rotatable section and thus arrange the bell cranks for operating the proper ejector slides, as well as to release the keys of the cash register.

The coin entering through the slot falls into the current coin tube, taking up a horizontal position, and the coins lie one over theother-t-herein. The slanting surface in the region of the current coin tubes, while incidentally allowing convenient space for the adjacent operating mechanism, is primarily intended to cut the tops of the current tubes obliquely and thus to permit coins in excess of the capacity of the current tube to slide on backwardly, off the block 11, which contains the coin tubes, to be received into a suitable tray 30 in the cash drawer. However, it will be seen that the current coin tube might receive coins enough to bring the upper side of the upperslug, of marked difference in appearance from the coins, may be placed on top of the coins in the auxiliary tubes and this slug will be delivered by the coin ejecting mechanism in the same manner as are the coins, which, being noticed, will give a signalfor refilling the auxiliary magazine.

It will be understood that a certain key of the cash register, such as the No sale key may be made to operate all of theselee tors, this feature of the operation being advantageous in delivering change. to the full amount of a coin inserted. However, this feature also becomes additionally useful in connection with the use of slugs, as above mentioned, since, when a slug is delivered. as a signal that the auxiliary tube is empty, the slug may be inserted into the current coin tube corresponding to the auxiliary tube from which the slug was ejected and the No sale key, or other key for this purpose, depressed, upon which change equivalent to the coin which should have been delivered, had both of the tubes not been empty, will be ejected for the purpose of. completing the change for that sale.

This will leave the slug in the current tube and this slug will be delivered therefrom upon the next operation of the ejecting mechanism of that tube. In,this way the slug is made to operate in conjunction with the parts of the register and change maker to facilitate the completion of the change and is also made to give an additional signal most coin above the rear edge of the upperwhich will be useful in case the operator,

end of the coin tube, which would result in stopping the next coin inserted and clogging the entrance to the tube, as Well as preventing coins from passing backward into the tray 30. Such a possibility is prevented by providing a rearwardly extending lug 31 on the forward or higher wall of the current coin tube, near its t0p. at such a point as will cause a coin, upon the preceding coin having reached a level which prevents this coin from falling past this projection, to rest with its rearward edge on the upper surface of the uppermost preceding coin and with its forward part on said projection in an inclined position, as shown in section in Fig. 11. Then subsequent coins so engage with this inclined coin that they will slide over it into the tray 30, as required. The auxiliary coin tubes forward of the current coin tubes are for receiving a supply of coins while the cash drawer is open and thus to supply coins when their respective cur rent coin tubes become empty. Thus, the supply of coins of any denomination is rendered more nearly continuous so that the convenience and accuracy of operation of the apparatus is increased.

For the purpose of informing the user that the auxiliary tube or magazine has also during the manipulation of the apparatus with the use of the slug, forgets the fact that the auxiliary tube is empty.

The ejector slides 20 are slidable forwardly and rearwardly in the slide carrier 32 which is secured to the lower side of the block 11. As shown, in Figs. 1 to 8, inclusive, each coin ejecting slide is provided with an opening 33 elongated from the front to the rear of the slide with semicircular ends and straight sides connecting them so that it is practically elliptical in shape. The slide carrier is provided with raised surfaces 34 in the groove 35 in which the slides are carried, and each slide has a recess 36 to fit over a corresponding raised part of the carrier. The elliptical opening 33, however, does not extend completely through the slide throughout its extent, but lugs 37 are left at its sides toward the rear of it, these lugs being so shaped that the opening which is constituted extending entirely through the slide forwardly of them will just pass the coin that is to be ejected by the slide. The normal position of the slide is such that the semi-circular rear end of the opening 33 coincides with the current coin tube or magazine. Thus. the lowermost coin inserted into this magazine will rest partly on surface 31 of the slide carrier and the slide 20 reaches its forward limit of movement, the semi-circular rear end of the opemng 33 coincides with the auxiliar coin tube or magazine. Thus any coins 1n the auxiliary or forward tube will then rest on this coin which has been brought forward.

from the current tube.

The slide carrier 32 is provided with rear-- wardly downwardly extending slots 38 passing through it in alinement with, and of equal width with, the elliptical openings 33 in the slides. These slots are so located in the slide carrier that when the slide is in its forwardmost position and the coin in the rearward part of the elliptical opening 33 is under the forward or auxiliary tube, the forward part of the coin will be resting on the raised surface 34 of the slide carrier immediately forward of the beginning of the backward and downward inclination of the slot 38. With the coin thus supported forwardly by this part of the raised surface 34, when the slide starts on its return backward movement, the coin, will be left there until the forward semi-circular end of the opening 33 engages with the forward edge of the coin and pushes it through the slot. When the coin passes through the slot it falls into a suitable open receptacle 39 mounted on the under side of the cash register casing.

Should there be no coins in the current tube or magazine, the opening 33 will, of course, pass forward empty, upon which, coming coincident with the forward or auxiliary tube or magazine, it will receive the lowermost coin therefrom and will then, upon its return backward movement, deliver this coin in the same manner as it delivers a coin which it has carried forward from the current magazine. Thus, the uninterrupted delivery of coins of any particular denomination is not dependent upon the rate at which such coins are inserted into the machine during the transaction of business, but may be insured by filling the auxiliary reservoir from the reserve of coins on hand at the beginning of the business, as hereinbefore mentioned. Also, should a coin, at any time, fail to be delivered from the current'tube. due to its taking up a wrong position therein, which positioncannot be readily controlled by inserting the coins through the slots 29, a coin is sure to be delivered from the auxiliary tube. At the same time, this reserve in the auxiliary tube is not drawn upon as long as coins are being h Pa of the device are so proportioned that when complished by of the current tube in which they belong will readily'pas's backward to the tray 30from which they may be taken and inserted into the auxiliary tube should this tube be exhausted. The filling of this tube, should it be exhausted during the day, is readily acmerel opening the cash drawer and inserting t e coins into the open top of the tube. I

As set forth in my former patent, in connection with the making of change for certain coins received, it 1s necessary to discharge two of the coins of like denomination, such as two dimes as change for a quarter, upon a. five cent sale. This is effected preferably by the use of two slides, as the slides 20 and 20", illustrated in Fig. 7 of the drawing. When connected to them by links and fulcrumed adjacent to each other as is best illustrated in Fig. 7 of the drawings. In this case, the upper slide 20" is the auxiliary one, and the slot 33", with which it is provided, has no lugs such as the lugs 37.

One of the other constructions which will accomplish the purpose of discharging two coins of the same denomination at the same operation is illustrated in Fig. 10 of the drawings, where the slide 40 is provided with two openings 33, having lugs 37 therein, similar to the openings 33 hereinbefore described. The current and auxiliary coin tubes 12' and 13, respectively, are located in the same positions as are the two tubes above described, and the slide carrier 32 is provided with an obliquely extending slot 38., as hereinbefore described. However, the slide 40 must move a distance sufiicient to bring its rearward slot 33 coincident with the forward or auxiliary tube 13, which, when the parts are properly proportioned, will be about twice the distance that it should move if it had only one slot as above described. This greater movement is given to it by providing a bell crank 16 of different proportions than the bell crank 16 used where only one slot is provided in the slide. The bell crank is operated by the trip or finger 7' in the manner hereinbefore set forth.

The manner of selecting the parts to be operated to optionally discharge one or two coins, bein fully treated in my former patent, nee not be herein set forth, it bemg suliicient to state that such means may be readily applied either to the selection of the roper bell crank to operate either or both of or to operate a slide with two slots or through its entire stroke two slides are thusprovided, both are provided with bell cranks the slides when two slides are used,

as may be required. It will also be understood that such a slide may be provided with more than two openings, and operated through a sufficient distance to discharge a coin from each opening with which it is provided, and from either of two coin tubes or magazines. In any case, the construction of the slide carrier and the peculiar manner of ejecting the coin remains the same. However, the coin may be ejected from the current tube, or, the current tube being exhausted, from the auxiliary tube, by providing a modified ejector slide 40, as illustrated in Fig. 11, which has a rearward opening 41 normally coincident with the current coin tube 12", and a forward opening 42 normally coincident with the forward or auxiliary coin tube 13". The slide is provided with a bell crank 16" connected to the slide by a link 21 and fulcrumed in a section 14" in the usual manner. A downwardly and rearwardly extending groove 41 is provided in the upper surface of the slide 40, beginning adjacent to the rear of the forward opening 42 and extending down to the forward edge of the rearward opening 41. The stroke of this slide 40' is such that the rearward opening 41 will be brought coincident with the forward or auxiliary tube 13". Thus, the lowermost coin in the current tube 12 will be brought under the auxiliary tube 13" when the slide is pushed forward in the operation of the device, while the lowermost coin of the auxiliary tube 13" will be carried forward in the forward opening 42 of the slide and discharged forwardly' of the forward termination 43 of the slide carrier 3'2". A pawl 44 is mounted in a slot between the current tube 12 and the auxiliary tube 13" pivoted at its end, and free to rise and fall at its front end, and when the slide 20" starts backward this pawl 44 drops behind the rear edge of the coin, which has been carried under the auxiliary tube in the rearward opening 41 in thevslide, and prevents the coin from returning with the slide. Then the forward edge of the coin slides up on the incline of the groove 41 in the slide, into the auxiliary tube or magazine 13". A recess 41" is left in the slide at the rear of the opening 40 so that the pawl 44 may fall behind the coin as stated.

lVhile the parts of my improved change maker are shown and specifically described as located in a cash drawer, and while certain of its features of novelty are particularly adapted for combining it with a cash drawer and with the mechanism of a cash register, it will be understood that these features also adapt it for use independently of a cash drawer, as, for, instance, they ma be used in conjunction with a cash registering mechanism, but located in a compartment separate from the cash drawer.

so that it is raised The bell cranks, preferably, are rovided with broad surfaces in the region 0 the terminations of their rearwardly extending arms 18 in the form of push plates 45, these push plates being provided with openings 46 in which the ends of the trips or fingers may engage to operate the bell cranks. By having these push plates, the bell cranks are adapted to be operated by the pressure of the finger, so that the coin ejecting mechanism may be operated independently of the keys of the cash register, when the drawer is open, which advantage is highly desirable in counting the coins or in making change independently of the registering of the sale, if such should be desired. The coins may be counted far more rapidly and accurately with my improved apparatusthan by hand. While thus especially convenient for manipulation independently of the cash registering mechanism when the drawer is open, the operation of the change making mechanism independently of the cash registering mechanism is rendered impossible when the drawer is closed. The drawer may be provided with any well known means for locking or otherwise fastening it in closed position, either to prevent the opening of the drawer or to render such opening so inconvenient as to discourage tampering with the contents by any one so disposed.

l'Vhere change makers have been provided on cash drawers heretofore, the ejector slides have been accessible for operation exteriorly of the drawer. In my improved change making apparatus, in the construction of the ejector slides, the only parts which are accessible from the outside of the drawer are such that they may not be operated to eject a coin by direct engagement of the fingers, the only means for operating them throughout their full stroke, which is necessary to eject a coin, being the bell cranks, which are entirely within the drawer, and inaccessible when the drawer is closed, excepting through the operation of the cash register keys.

Although the ejecting mechanism of the change maker is fully under the control of the cash register mechanism, the opening and closing of the drawer in which the ejecting mechanism is contained is not interfered with. The lower end of each trip or finger such as the trip or finger 7 is bifurcated, having a forward short member. 47 and a rearward longer member 48, this rearward longer member 48 being adapted to engage with the rearward part of the push plate 45 and limit the forward movement of the trip or finger under the action of the keys through the selectors, and thus position it,- so that upon further depression of the key theforward shorter member .47 will enter the recess or opening 46 in the push plate and effect etlicient engagement between the trip or finger and the bell crank to operate said crank and eject the coin.

It will be understood from the above description, that considerable modification of trations and specific description, but
