COIN-CHANGING- MACHINE.

Patented June 23, 1914.

Be it known that we, WILLIAM E. MATH- Ews and ERNEST I. vOREM, citizens of the United States, residing at Indianapolis, county of Marion, and ReXville, in the county of Ripley, respectively, and State of Indiana, have invented a new and useful Coin-Changing Machine, of which the following is a specification, reference being had tothe accompanying drawings and to the letters and gures of reference marked thereon.

This invention relates to a machine that is adapted to be used in business houses, such as banks, offices, mercantile houses or other places, for quickly and accurately changing coin into coin of smaller denominations, the invention having reference particularly to a cabinet that is adapted to.

stand in a convenient place, as on a counter or table, and contain quantities of different sizes of coins representing different money values which may be dischargedfrom the cabinet upon the insertion into the cabinet of coins of largersizes and denominations, the cabinet containing suitable coin-controlled mechanism to be operated by an attendant.

The object of the invention is to provide a reliable coin changing machine that may be so constructed as to be adapted to be cheaply produced and which shall be accurate whether or not the coins are of standard thickness; a further object being to provide apparatus of the above mentioned character that will enable business houses to conveniently change coined money without liability of errors and loss in transactions.

A specific object is to provide mechanical apparatus that will enable merchants to `change the money of customers'for them and then receive the exact amount of money from the customer required to cover the purchase of merchandise, so that there can be no mistake in returning the correct change to the customer.

A still further object is to provide a coin changing machine that will be so const-ruoted as to enable the proprietor to readily keep a check on the value of the money i handled.

number of coins controlled by larger coins; and. the invention consists further in the novel parts and combinatlons and arrangements of parts as hereinafter particularly described and claimed. v

Referring to the drawings, Figure lis a perspective view of the improved coin changing machine; Fig. 2, a vertical sectional view taken through the foremost receptacles in the magazines; Fig. 3, a section on the plane of the line A A in Fig. 2 with the lower portion of the cabinet broken away; Fig. 4, a fragmentary section on the plane of the line B B in Fig. 3;Fig. 5, a fragmentary section .on the line C C in Fig. 8; Fig. 6, a fragmentary horizontal section slightly below the. line C C showing parts obscured in Fig. 5; Fig. 7 a fragmentary section on the line D D in Fig. 5; and Fig.

8. an inverted plan view of one of the coin magazines.

Similar reference characters in the different igures of the drawings indicate corresponding elements or features of construction herein referred to and described.

The case constituting a part of the cabinet preferably comprises a main portion and a removable cover portion, the main portion comprisingga bottom l, a front 2, a back 3 and sides 4: and 5.v A suitable number of magazines 6, 6, 6b, 6, 6d, are employed and suitably supported rotatably and inclosed in the case, each magazine being cylindrical and of any desired' length, all being equal in length however and arranged uprightly. Each magazine has a suitable number of coin receptacles 7 and 7 formed therein and extending therethrough longitudinally, the receptacles in the different magazines being of suitable diameter to receive coins of diferent diameters, as for instance the receptacles in one magazine have f the required diameter to receive one-cent pieces, those 1n another magazine to receive ten-cent pieces, and so on. The wall of each cylinder preferably has longitudinal slots 8- zine asv required. The recesses however, inay be formed in the wall elsewhere than in the slots if desired, the number of the recesses obviously depending upon the number of coin receptacles in the magazine.

AThe magazines may .be constructed of wood in a simple and relatively cheap manner, in which case a. suitable number of metallic plates 10 are forced into thel lower end of the cylinder so as to be iiush wlth the end and they are arranged umformly about the axis of the cylinder, one end of each. plate Abeing in contact with the middle portion of an adjacent plate, the plates bemg arranged at oblique-an les each to the other, and recesses 1l are ormed in the -end of the cylinder adjacent the outer sides of the platesv into which a pawl may be projected for periodically rotating the magazine, the plates and recesses constituting the'equivalent of a ratchet-wheel which, however, may be variously formed when the magazine 1s com posed entirely of metal. Eac magazine 1s provided with an axial shaft 12 which extends beyond the ends thereof, the ends of the shaft Preferablyv being pointed.

The different magazines and operating mechanism therefor are structurally; independent of each other and arranged .1n different compartments in the case, as will further appear, so that a description 1n detail of one suilices for the others. In order. to support. each magazine. and its Ioperatlng and cont-rolling mechanism, a pa1r of ' suitable guides 13 and 14 are arranged horlzontally and extend from the back 3 to the front 2 and preferably to the plane of .the outer face of the front, the guides being `supported by the front and the back at a suitable distance apart. A suitable base 15 is fixedly supported on the two guides, and a plate 16 issecured upon the top of the base. The base has a shaft socket 17 therein and sup orts two standards 18 and 19 between w ich a magazine is arranged upon the plate 16, the shaft 12 extending intothe socket through the plate for guidance. A

bar 20 is secured upon the tops of the standards and is provided with a screw 21 having its lower end suitably shaped and seated upon the upper end ofthe shaft 12, constituting an adjustable bearing. The plate 16 has an aperture 22 therein arranged near the front 2 of suitable diameter to receive a coin of the size contained inthe magazine, the plate beingof the same thickness as the coin; or to compensate for inaccuracies the late may be slightly thicker than the coin. lilach base 15 has a guide channel 23 formed therein at the sides of which are vertical guide faces 24 and 25. A suitable number of coin extractors 26, 26, 26", 26e, 26d, are

provided, each of which is mounted slid-- the guide channels therefore being of differ- `ent depths, so that the extractors till ,the

channels andiit closely under the plates 16. Each extractor has an aperture 27 therein which normally is 1n register with the aperture 22, the latter being in register with the 'extractor forward on the base and from under the coin remaining in the aperture 22. TheI extractor has a longitudinal slot 28 therein clearing the lower portion of the shaft 12. The forward ortion of the extractor has two stop projections 29 and 30 thereon which engage the forward side of the base 15 tolimit the inward or rearward movement 0f the extractor and accurately position the aperture 27. The inward or rearward end of the extractor has a downwardly projecting'finger 31 thereon adapted to be engaged by a coin for moving the extractor forward to discharge the coin. In order to operate the extractors a suitable number of operatingbars 32.I 32, 32, 32, 32d, are provided,- each bar being suitably mounted slidingly in the two guides 13 and 14 beneath the base that is mounted upon the guides, the operating bars extending nearly to the back 3 and also forwardly through the front 2, each bar being provided on its forward end with an operating handle and also an upwardly extending lug 34 normally engaging the outer end of the extractor mounted in the base, the lug being adapted to retract the extractor. Each operating bar has an aperture 35 therein which under certain conditions of operation is brought under the aperture 27, to lpermit the coins to fall through the operating bar into a chute 36 secured to t-he front 2 below the bar. The under side of the operating lbar has a longitudinal groove'37 therein which, in the rear end portion of the bar, extends through to the upper side ofthe bar to form a narrow slot, and a suitable ejector arm 38 has one end thereof connected to the front 2 by means of a pivot 39, the opposite end cxtending into the groove and being adapted to be forced upward into the slot by means of plate springs 40 and 40 secured to the front 2 and extending in contact with the under side of the arm, two springs preferably being employed so that the mechanism need not become disabled in case of fracture of one .of the springs. Thefree end of the ejector arm normally rests in the bottom of the groove and can be forced upward into the slot only when the operating bar is'projected forward.4 A As ring finger 41 is mounted on the operating bar and extends upward through the slot 42 formed in the extractor 26 and also through a guide slot 42 formed in the plate 16, the end of the 130 monate finger resting against the under side of the plate when the bar is retracted and is projected upward into a recess 11 kwhen the bar is projected forward to rotate the adjacent magazine. 'Ihe operating bar 32 is forcibly retracted and normally held in retracted position by means of two coil springs 43 and 43 connected to the bar and also to the rearward portions of the guides 13 and 14 and must be pulled forward or projected by hand. A stop finger 44 is secured upon the extractor 26 and when the extractor is moved forward enters a recess 9, for accurately establishing the position of the magazine after it has been rotated, so as to bring a receptacle fair with the. opening 22 in the plate 16.

A convenient arrangement of coins provides for holding one-cent pieces 45 in receptacles of the magazine 6, five-cent pieces 46 in the maga-zine 6, five-cent pieces 47 also in the magazine 6", ten-cent pieces 48 in the magazine 6 and twenty-five cent pieces 49 or quarters in the magazine 6d, the aperture in the extractor 26 holding ve coins, the extractor 26 holding two coins, the extractor 26h holdingve coins, the extractor 26c holding tive ten-cent coins, and the exi tractor 26d holding four coins.

Revert/ing to the opera-ting bar- 32 it will beseen that the upper rear portion thereof has a recess 50 therein in which a coin 46 is inserted in Figs.- 3, 4, 5 and 7 the coin being on edge and in Figs. 5 and 7 is car-` ried forward against the linger 31 and has caused the extractor 26 to be moved forward nearly to the limlt of its forward movement.

Two connected curved guides 51 and 51 are mounted on the guldes 13 and 14 and extend over the coin, the guides having slots 52 and 52 therein respectively, through which the coin will be ejected bythe arm 38 when the rightly and having lugs 54 andA 54 on oppo' site sides thereof, the upper portion above the lugs being connected to two slightl elastic upright rods 55 and 55 whic are secured at their lower ends upon the guides 18 and 14, thc lugs 54 and 54 being in contact with the forward sides of the rods So as to tend to yieldingly hold the lower end of the chute forwardly, the lower end being provided with a lug' 56 adapted to be engaged by the rear end of the operating bar 32 when retracted to push the lowerend of the chute rearward slightly so that the chute `will discharge the coin fairly into the recess 50. The chutes are of different diameters so asto admit only a pref.

guides 51 and 51', and if a coin of too small diameter is admitted it will pass under the finger 31 without operating the extractor. Preferably the forward -side of the chute has a recess 53 therein which may be of proper proportion so as to permit the coin to pass through.

Preferably a guard plate 57 is placed rearward of each magazine and supported on projections 58 and 58 extending from the standards 18 and 19. Also in order to prevent the coins from falling into the-mechanism-when ejected from the operating bar a ldelecting guard 59 is mounted on the guides 13 and 14 and is provided with a coins are thrown, the guard having an opening 61 through which the chute 53 extends, a deflector 62 being secured to the chute and covering the opening 61 forward of the chute, so that'the coins may drop upon the guard 59 and roll or slide off and fall at either side of the operating mechanism below.

The cover portion of the case comprises a front 63, sides 64 and 65 and a-back 66, all being secured toa top 67 in which` are coin receiving guides 68, 68, 68", 68, 68d, for guiding different sizes of coins to the different chutes 53, the guides being designed to receive live-cent pieces 69, ten-cent pieces 70, twenty-ve-cent pieces 71, fifty-cent pieces 72 and one dollar pieces 73, respectively, the designated characters being arranged on the top 67. The top 67 has a suitable number of partitions 74, 7 5, 76, 77, secured thereto and extending down between the different bases and magazines thereon to a distance corresponding to the plane 0f the top of a drawer 78 `which is suitably supported in the case and has partitions 79, 80, 81, 82, therein immediately below the other partitions. The cover portion of the case is suitably iitted onto the upper end of the main portion of the case so as to be removable. Preferably an ordinary or suitable money drawer 83 is arranged on the bottom l of the case in which paper money or a reserve supply of coins mayA be kept. The drawer 78 preferably is inserted through the back 3 115 and provided with a lock 84. Preferably the cover portion of thecase is locked tothe main portion by means of the drawer 78, the sides 64 and 65 of the cover portion being provided with extensions 85 and 86, re- 120 spectively, which project downward at the inner sides of the sides 4 and 5 of the main portion of the case and are provided at the lower ends with guides 87 and 88 adapted to slidingly support the drawer 7 8, so that 125 when the drawer is in normal position in the back 3 the drawer and consequently the cover portion cannot be lifted from the main portion of the case. The cover portion may be removed from the main portion 13o when the drawer 78 is entirely removed' chute-into the recess or holder 50, and then` the attendant pulls the operating bar 32 forward, the bar in its movement carrying the coin against the finger 3l and forcing the extractor 26 forward with four twenty-fivecent pieces or quarters in the aperture 27 until the coins are moved forward beyond the front 2, when they drop through the registering aperture 35 into the chute 36 from \vhich they may be received into the attendants hand. When the extractor has moved the four coins from beneath the coin remaining in the aperture 22 the remaining coin is supported upon the extractor until the latter is returned to normal position, when the pile of coins in the next adjacent receptacle in the magazine which has been brought forward descends so that the four .lower coins in the pile enter the aperture 2l, it being understood that while the operating bar is moving forward the magazine 1s being rotated so as to carry the pile of -coins in the foremost receptacle away from the coins that are in the apertures 22 and 27. When the controlling coin reaches the slots 52 and 52 it is ejected and forciblv thrown up through the guide 60 and falls into the compartment in the drawer 7 8 that is below. the bar 32d. Four quarters having been quickly obtained in exchange for one dollar, if it be desired to change a quarter into fivecent pieces it is inserted into the guide 6Bb and the operating. bar 32" is then manipulated as before described, and tive five-cent pieces are obtained. A {ive-cent piece, if desired, may then be inserted in the guide 68, and having manipulated the operating bar 32 it will be seen that five ono-cent pieces are obtained. If it be desired to change a fiftycent piece it is inserted, in the guide 63 and therefore five ten-cent pieces are obtained. If it be desired to change a ten-cent piece it is inserted in the guide 68 and two five-cent pieces are obtained therefor.
