CHANGE-MAKING MAcnrNn.

Specification of Letters Patent.

Be .it known that I, CHARLES AUmana, a

`citizen of 'the United States, residing at- Lisbon, inthe county lof Ransom and State of North Dakota, have invented-certain new and useful Improvements in Change-Mak-V o, finger pieces corresponding to thefactors with entering into the computations.

The ob3ects of the invention are to sim- 'plify the mechanism for making the computations and at the same time increase both the accuracy and the capacity of the machine. .Y l,

The invention consists primarily in a machine embodying a control device or selector having motions in. two intersecting planes, the motion in one plane being controlled and determined by a set of keys corresponding to one set'of factors, and the motion in the other plane being controlled and determined bya set of keys corresponding t-o another set of factors, any of which may be used in the computation, there vbeing means whereby the :position of` the selector will determine the result, such, for instance, as the discharge or indication of the proper change to be given where the purchase price is one factor and the amount deposited the other factor inthe computation. 1 y y More specifically, the, invention may be said to consist in a machine embodying a selector having a rotary movement about its axis and a bodily movement longitudinally of its axis, the two movements being controlled and determined by diderent sets tofkeys, whereby the selector may be positioned.` any portion of its surface 1n proper relation to the cooperating mechanism lthrough which the desired result is effected.

"The invention further consists in certain novel details of construction and combinationsand arrangements of parts all as will .Fig 2 is an elevation vation; and Fig. p

In the machine `adopted for illustration of the present invention, provision is made.

looking at, the left but it will be 'understood that the principles l involvedA in theconstruction of the machine and the mechanism lillustrated may be adapted for handling` fractional amounts, although the number of control keys would have to becorrespondingly increased, and

insome instances additional selectors with provision whereby from the keys, as for instance, a selector might be provided for handling dollars, as

in the machine' illustrated, and another selector provided for handling fractional curthey might be controlledrency, the principles of operation and construction of selectors, however, being simim the accompanylng drawings.

.The machine embodies in its general c onstruction the frame 11 having suitable bear-` ings therein for horizontal and vertical shafts to:loe presently described, and while it may be providedwlth a-cover or casing for t. i the working parts of the machine, such cover or casing has been omitted from the drawings, thus leaving the mechanical parts exposed to view. v

v Journaled nin two parallel upwardly extending portions of the main frame, is a horizontal shaft 12, upon which shaft there is mounted a selector cylinder 13, the connection between the cylinder and shaft be-` ing such that they rotate in unison, but the cylinder is free to slide longitudine ly of kl he shaft, the connection, if desired, bev ing in the form of anordinary spline or key workingv in a groove-or channel 1n the shaft Fheselector cylinder vis provided lgaita face with a plurality of perforations orl apertures vvhichv are so arranged that when brought into proper relation to cooperating parts they will control such parts 1n performing the functions for which the ma- Y chine lis designed.- Mechanism for accomis of novel construction and is so controlled arranged, the d esire in its rotary and longitudinal movements that a large proportion of its area may be utilized and the capacity' for making varied'- computations greatly increased. )ne set of keys, for inst moe, w1ll control the angular positioning of the selector, whlle another set ofk'eys .willy control 'its vposition longiv,tudinally of its axis and by having said sets of keys correspond to the factors entering into the computation, it will be readily understoodv that the selector may be positioned by the operation of any portion of its surface to the desired position, and by havin the a rtures ro e l resulrtwill belefztbd For convenience in positioning the selector angularly about its axis it is provided with a. series of bars oryrbs 15 of progressively vvarying length and extending parallel with the axis. For cooperation with these barsor ofwhich when pressed inwardly lis adapted to arrest the-rotation of; the selector with the appropriate rib restingion the actuated key.

4cylinder at different Theposition with the selectorarrested by a key is well illustrated in Fig. 5, where it will be seen that the front rib 15 of the selector is resting on the inner end of the key bar 66. The longitudinal movement-V of the selector is also determined by a set of keys 65, said keys being arranged fin proper order to arrest the longitudinal movement of the points, thus as shown in said Fig. 5, the movementl of the selector cylinder 13 toward the left has been arrested by the contact of the edge of the Acylinder with the key bar 65, and it will be understood that the other keys and166 would correspondingly determine the position of direct control of yeo k positioning result tojfbe effected.

.Various mechanisms may be provided for operating the selector and for effecting the the selector by the sets of eyjs so;y that its angular and `lon position may be accuratelyl determined-for surface of 'the selector, which determine;the Infthe simple `form of machine illustrated the keys to bringy is provided a series of keys 66 '66p The shaft 21 gitudinal'.

the forwardzrotation' ofthe kselector about its-axis is yeffected by a spring liwhieh is secured to the cylinder at one end, coiled about the shaft 12 and at the other end held in a slot 17 in a plate 18 carried by the main frame. The spring 16 exerts a constant tendency to rotate the selector toward the front of the machine, as shown by thearrows in sprin to slid the cylinderin its proper normal position and to return the same to that normal position after having been actuated, the shaft 12 is provided at one end with a pinion 19 meshing with a gear segment 2O journaled Figs. 2 and 3,y

while the retention of the outer end of the in the slot 17 leavesthe 'cylinder free. e longitudinallyof its shaft. To hold on a shaft 21. The shaft 21 is provided with an arm 22 having a pin 22a the segment 20 to return or til the shaft 21 is actuated. The shaft 21 at its opposite end is provided with a gear segment 23 with which meshes a pinion 24 rotated by a crank handle 26. They rotation of the crankhandle in the-direction indicated by the arrows. in Figs. 2 and\3 will therefore cause the pin 22to inove away from in front of the'v segment 20 and said segment 20 will be left free to advance in accoperating with' hold the same uncordance with'the rotary movementl of thev selector under the inuenoe of the spring 16 toa point where such rot-ary movement is arrested by the uated key of the series is however free to continue its forward serves to actuate other parts of the mech.- anism, as will be presently described.

The mechanism-for moving the selector longitudinally understood from an inspection of Fig.4 4, wherein it will be seen that-a4 carriage 33 is mounted to slide longitudinally on guide bars or Ways 32 on-the main frame. Said carriage has arms 35 and 36 embracing the selector, the arms 36 however being pivoted on the carriage and held in operative position for moving the selector'byf spring 37, the arrangement being such that if the car- -riage 1s moved toward the right in Fig. 4:

and theA selector is arrested lby one of the key bars 65, the arm 36 will yield, permittm the carriage to continue lts movement, whlle the selector remains at rest. For moving ythe carriage itis provided with a stud or antifriction roller projection 34.working in a groove 30 in a cam cylinder 29 mounted on a shaft 28.v The groove 30 in the cylinder 29 is at theends made substantially circular or in a plane perpendicular 'to the axis of the cylindenwhereby the cam cylinder 29,willmake"a partial orv almost complete rotatiomifnecessary, before the movey ment ofthe l 'uring such time they selectorv may be pocar'rlagepfis inaugurated, and

siti'oned angularly without interference -or retardationby the ymechanism for moving movement of Vnit-ation and` ioo of its axiswill be readily it longitudinally. ,'lihe shaft l28 onvvhich `the cam cylinder 39 is mounted is provided at oneend, see Fig. 2,With'a-pinion 40,`

' connection-` 23,as shown in said Fig. 2.

cont-act with the `actuated key of the group From the 'foregoing description, the op eration of 'setting the selector will be readily understood, for instance, one of the keys of each of the groups 66 and 65 are operated and the crank handle turned inthe directio-n indicated by the arrow with the result that during ,the .initial movement of the crank handle the selector is permitted to turn under `the influence of its spring until arrested by the 'appropriate rib 15 coming `in G6. After the completion of this operation `the rotation of the cam cylinder 29 causes the cam portion of its groove 30 to move the carriage 33 together with the selecto-r longitudinally of the shaftl '12, until the selector is, arrestvedby .engagement with the inwardly projected end of the actuated key of the group 65. Inasmuch as in the longitudinal movementofthe selector the rib 15 would move out of engagement with the actuated key ot vthe group 66, provision is made for retaining the selector in its proper angular position by causing one of the ribs toimmediately move into engagement with a longitudinal guidewayl when' the longitudinal movement of the selector is inaugurated. This longitudinally extending guideway is conveniently the upper Aedge of the plate ,18,v which, as shownin Fig. 2,- lies in position to pass under `lany' one of the ribs which may be in posit on at the time the longitudinalmovement is ina gurated.. The guide thus lformedby the ed le of the plate 18. will prevent any further forward rotation of the selector under the influence of its spring, and while it might be arranged to permit the selector to return to normal position the return movement of these-lector takes placeonlv after it assumed its normal longitudinal position on the shaft and is out of engagement with the aforesaid guide formed by the plate 18.

A The keys (35 and 66 are preferably' formed by bars mounted to slide in suitable guides on the main `frame-and at their outer ends are provided with finger pieces, 67. They are rusually spring pressed in an outward direction as by springs a, Fig. 2, and they are held inwardly in their operative position spring pressed latches which will coperatewithprojections 69 on vthe keys Whenever the latter are pushed inwardly. For releasing thekeys and permitting 'the-m .4 to return to normal position a trip 71 over.- lying the' latches 70 is provided. Said trip' is pivoted at #2mn the main frame and @basa -link ponnebtfion-73--extending down .to'an arm 74 on a bell crank lever pi'` tied pressure on the fingerpi'ece or key 77', 'it is obvious will depress the inner end of the ,trip 71 vso astov release thecatches '70,"thus providing for' the -release ot'v any key which may/have been incorrectly operated or for Y the manual release of the keys betore the selector is returned to its normal position. Forautomatically 'releasing the keys dur ing the return of the selector to its normal position a third arm'78 is provided on the sha-'tt carrying arms744 and 76, which arm 78 projects into position to coperate with a pawl 79 .pivoted onl the gear segment 23 (Figs. 1 and 2), the relation of the parts being as shown by the dotted and 'full lines in Fig.- 2, Whereby'as the segment-returns toward its normal position, the end of the pawl 79 engaging the arm 78, depressesthej latter and then, owing to the'change inthe angular? relationship of the parts, slips ofi 'offthe end of the arm 78 and the parts assume the position shownin full lines with the keys released, and the catches 70 lagain move into position4 to retain a vkey when actuated.

The mechanism controlled'hy the Selector and'throughwhich the results aimed at are attained, consists generally of a 'seriesof spring pressed pins mounted in a'carriage or carrier adapted tobe advanced atfthe proper time iorl cooperating with the selector, the apertures in the selectorperniitting the `pins toy enter which are to control the actuation of the mechanism, While, if no apertures are in position for the Vpins to enter, the mechanism will not be operated. By the use of comparatively few `pins it becomes possible to` control 4the operation of mechanism fo-r'discharging coins of varying amounts, and if deslred there 1s an alternative arrangement to cont-rol the discharge of paper money-'of equal value.

Asishown in the accompanying drawings the series of. spring pressed p1ns44 are mounted to `slide vertically in` a' vertically movable carriage or carriery 43. Theicarriage or carrier 43 is mounted onthe upper end of a shaft 42 adapted to slide in a bearing 41 in the main frame, said shaft at its lower end being provided with a yoke 102 which passes around beneath the shaft 21 in position to belengaged and depressed by a cam 101 on said shaft. The cam 101 cornes into operation to depress the carrier 43 and pins 44 after the selector` has been posi tioned. The return movement ef the carrier, pins and parts connected therewith maybe effected by a spring, such. for instance, as indicated` at 103 in Figs. l1 and 3.

`control of the coin discharging mechanism.

, brace fractional'currency, as heretofore indicated. y f

The lmechanism for, discharging silver coins up to four dollars, consists essentially of a coin stack 59 in which the silver dollars are piled and having at the bottom four superposeddischargers each adapted to disf charge a single'coin, and, whenall'are actuated-to disharge vfour coins. The discharg- 'ing'slides are indicated in the ldrawings by the numbers '50, 51,- 52 and 53, each provided at its outer end with a lockvy pin 54normally held elevated and with its upper end seated in a ixed'locking bar 49 by a spring 55 (see Fig. 5),v but adapted to be depressed to enter "a groove 56 ,in` afreciprocatory 'driver or bar 56. Obviously when depressed, the upperends of the pins move outof the locking bar 49 and into the driver 56, and the reciprocation of the latter will actuate the ejectors or any one of. them, whose pin is in engagement with the bar to discharge one or more coinsas the case may be. The control of the pi'is7`5'4 is effected from the arms 45, before referred td, through the medium of the rods 46, the lower ends of iwhich extend down 'into the locking .bar 49 in position to' coperate with anddepress the pins' 54, whereby the ins 54 will be moved out of engagement wit the lookin g bar, and into engagement with the reciprocatory driver 56. During the reciprocation ofthe .bar 56, the upper ends of the pins 54. will slide on the under surface of the locking bar 49, as will be readilyunderstood from aninspection of Figs. 1, 2 andv 5.

The coin ejector slides A50, 51,152l and 53 arepreferably arranged soy that theupper slides will operate o r insure the operation of allof the ejectors below it, thus the upper ejectors` are' 'provided with` pins 50 Whichextend down to .en age the lower ejectors as shown in Fig. 5, w ereby the actuation of the ejectorsO, 51 and 52 alone becomes impossible without theactuation of v the ejector 53, although ejector 53 may be actuated' alone to discharge a sin le coin, and'52 and 53 may be actuated to discharge two coins, etc.

The barf56 slides ways 56El in the vmain' frame, see Fig. 4, and is reciprocated bv arms 57en'a shaft60. f The shaft 60 at one end carries a crank 'arm 61 which at its ex- L tremity is joined to a sliding shaft 62 extending, backfalongside of the, main .fran-:e

time the other edge of the and havin struck by t e end 63 of the gear segment 39,

just as thelatter is completing its forwardA movement and after it'has positioned the selector longitudinally of the shaft. By

pushing the. rod yor frame 62 forwardly, the

a projection 62'L adapted to be` bar 56v is actuated to advance any coin ejector which at that time may be in engagement therewith through the medium lof l its in 54. The return movement ofthe bar. 56 1s effected by the spring 64 which at one end may beconnected with the bearing 64a j in which the' end of the rod, shaft or frame 62 takes its bearing, as shown in Fig. 2.

As before stated, the ejectors 50 to 53 are competent to eject coins up to the value of four dollars, and.y in order to permitv of the giving of change in amounts equal in value `to nine dollars, provision 1s made whereby when' the proper pin of the series 44 is operated a five dollar billwill be. discharged.

To accomplish this there isl arranged along one side of the` machine a receptacle 81 which is divided by partitions 82 into compartments adapted for the recept-ionv of paper currency, the currency of theproperv de-y nominationsbeing folded and placed b etween superposed plates 84lin thecompartments of the receptacles. One of the compartments is adapted for the holding of five dollar bills which are folded and placed between t-he -plates 84, and these plates', together with bills which may be located between adjacent platesl are discharged insuccession through the medium of the arm .1 46 connected with the last pin 44 and the rod 48 carried by the arm 46 which extends down into osition to coperate withand .actuate paw 93. The pawl 93 has an inclined face 93L with which the endof the rod 48' engages, whereby the pawl will be moved inwardly so as to enter and engage with a notch in the lowermost plate 84. The plates are supported atone edge on vledges 86 and at the outer edge by short pins 83. The edgesof the'platesare notched at 85, the notches being in such position that upon any'plate being drawnv forwardly it. will bring the notchesrtherein into position to register with the pins 83 and at the same plate will be moved off` of' the ledge 86 with the result that the plate is free to drop, and of course Iwill permit the currencysupported thereby to drop or be ejected from the machine. The pawl '93 is mounted on a reciprocatory carrier 94, preferably receiving its m'otionv from the reciprocatory bar v56. As shown in the diagrammatic view, Fig. .5the carrier 94 is connected directly with the bar 56 by a connection I5'6", but in the machine j as preferably constructed and as shown in -the other views, the shaft 60`carries at 'one' end a crank` armv "56a which is connected through a link 5T with thecarricr 94 whereby when the shaft 60 and reciprocatory .bar

56 are moved, the carrier will be correspondin ly moved, and, if at that time the pawl l 93 has been moved into engagement with the 'bottom plate 84 in the receptacle,as by the depression of the pin 44 and :ii-m46, said bottom plate will be moved in a direction to effect its release from the receptacle and the discharge of both the pla-te'and the -ci'irrency held thereby.

y In some instances itis desirable to pro? vide for the payment of change either' in coin o1' in paper currency, and this may be vaccon'iplished by providin l a series of cur rency compartments 'in t e receptacle 81,

i such currency compartments being adapted to contain bills, which will be discharged by the operation of the selector controlled pins which as heretofore described Will e-Eectthe discharge of coins of like value, it being understood ofl course tthat provision lis made for checking the `discharge ofcoins when it is desired to make change in paper currency.` For operating the currency holding and discharging mechanism, the bills of proper denomination are folded between plates 84,

'such as before described, and the carrier 94 vis provided with 'pawls 93, correspond1ng to the pawl 93 before described. `Each of the pawls 93 is provided With-an inclined face `92, and with each there is adapted to cooperate a spring pressed pin v91 mounted in bearings on the side of the receptacle 81 and `adapted when depressed tomove the paivls int-o engagement With the'plates. vAbove the spring pressed pins 91 there is arranged a series of dogs 88, one dog foreach pin and all of the dogs are mounted ona carrier 87 movable longitudinally of the receptacle and adapted when in one position to bring the dogs into proper position for depressing the -pins 91 Whenever the branches 90 of the rods 47- are depressed. Conveniently, the dogs 88 are provided with heads 89 which are moved .beneath the arms 90 by the longitudinal movement of the dog carrier 87, said dogs thus acting as interponents between the arms 90 and the pins 91. i The dog carrier 87 may' bemovedby hand, and heldin posit-ion by a locking pin 9S, Fig. ,5, and its movement may simultaneously closeya door 97 for the discharge opening in the bottom plate 53 of l the coin stack 59, such simultaneous closure of the door 97 being effected through suit-` able connections indicated atv 95, 96, in. Fig. 5.` In the preferredconstruction, the door 97 ,for closing the-co1n discharge opening and prevent-in the ejection of coins is controlled y a han le,V 99, Figs. 1 and 3 which ,when

swung from the position shown in full lines to thatshown in dotted lines in Fig. 3, will close the coin discharge and by engagement vvith. the in 99"(` on t e dog carrier 87 will move the atter into position for thedogs to operate in the manner heretofore described.

The handle 99 Will be retained in its position for preventing lie discharge of coins and holding the parts ready for the discharge of ing adapted to discharge or cooperate with the two vbottom pla-tes, and the other with a single bottom plate. The paWlcoper-'ating with the two bottom plates is actuated by an arm of the rod 47 which controlsthe 'discharge of four coins and Will etl'ect the discharge of four dollars in currency of four dollars in coin as the case may be. The

pawl cont-rolling the bottom plate of the two dollar bill compartment is itself'l controlled by the arm 90 of the rod 47 which coperates with the coin ejector 52,- and consequently when actuated will discharge two dollars, as will be readilyr understood.V With this arrangement one, two, three orv'four dollars in either bills or coin may'bevdischargedl at the option of the person using the machine.

` The operation of the machine may be briefly described as follows. representing the value of a purchase is pressed inwardly' until latclied and held in its operated position. 'A key 66, representing the amount received from the customer' and which of course is more than the value of the purchase is also pressed in until A key 65 caught and held in its operated position. y

The handle 26 is now rotated the direction indicated by the arrowin Figs. 2 and 3 whereby the shaft 21 is rotated through the medium of the -pinion 24 and segment The arm 22 moves away from `tlv-f regu-ier.. 20 or allows the segment 20 to advance as the selector is rotated under-t eI influence of its im elling/ spring until the selector is arrested y the operated key 66. "the continued rotation of thev shaft ai, ltogether rwith the se ment 39 .meshing with the pinion 40 on t e shaft 28, causes the cam' cylinder to rotate and advance the carrie 33 and selector longitudinally of the sha t 12 or until srch movement of the selector is arrested by the operated key of thagroup 65.l The selector is now.positioned reis.,1 the proper apertures in position for`A controlling the mecianism for egectmg the 'pro er amount of change. The continued rotation of the "shaft 91 brings the cani arm 101 into engagement with the yoke 102, whereby the yoke, shaft to which it is secured'anv .The ,Proper carrier 43 will be depressed` llo i pins finding'apertures' to receive them in the selector, will continue to move downwardly vwith `the pin carrier 43, while .the movement of the other pins will be arrested. Those pins 44 which continue to move downwardly carry withthem the arms 45 or 46,

. and by so doing the handle 99 will havev together with the rods 48 and the arms 90 on the rods 47. The actuated rods 47 will,

-through the pins' 54, cause the engagementv case it is not desired to discharge coins, the

doorl 97 will have been previously closed moved the dog carrier into position for the dogs l88v to form interponents between the arms 90 and the ins 91, whereby paper currency will be dlscharged instead of coin.

. As soon as the discharge of either the paper currency or coin is effected, the parts are returned to their normal positions -by arevers'e rotation of the handle 26 .and during such reverse rotation the pawl 79 will co operate with the arm 78 to release the o erated keys .and restore them to their normal position. -As the carriage 33 returns to its normal position shownin Fig. 4, the spring pressed arm 36 will be invariably returned to its normal-position by striking a projec-v I claim as new and tion' 4or shoulder 38 on 4the frame, but it will be understood that this spring-pressed arm 36 is but one of manyforms of: looseA connection which may -be interposed'v be-y tween the carriage and the selector whereby the carriage may be permitted to make a -full stroke while the selector is arrested at an intermediate point. v Having thus described my invention what ing a cylindrical surface and movable both angularly and axially, of two corresponding separate sets of keys each set comprising a plurality of independent keys with means whereby the keys of one set determine the angular movement, and the keys ofthe other set determine the axial n'iovementofy i the selector.
