This invention relates to improvements in change making'devices provided with means for carrying coins and means operable to discharge coins from the carrying means.

An object ofthe invention is to provide a change maker of novel, inexpensive and efiic'ient construction wherein the coins may be caused to fall from the device more nearly in a vertical direction, and wherein the coins may be inverted and stacked one upon another in the hand of the user of the device as the coins are discharged from the device. y

Another object of the invention is to 1 eliminate the use of screws, bolts, nuts and rivets in securing the parts of the device together.

Another'object of the invention is to improve the severalelements of the frame 29 structure and coin ejecting mechanism of the device whereby advantages not heretofore present are gained.

The invention resides'in the elements and the combinations of them hereinafter de- 1 5 scribed and claimed. I I

Figure le is a side view of one of the 56 coin tubes.

Referring to the drawings, the frame structure of. the device comprises a bent sheet metal member 2 and a series of vertically-disposed, spaced tubes}; of varying no sizes adapted to receive and carry coins of varying diameters. Thesheet metal member 2,.as herein illustrated, is formed of a singlepiece of material and it comprises a top plate 7, a bottom plate 8 and a rear plate 9 connecting the top and bottom plates. The forward portion of the top plate 7 is provided with semi-circular cutout portions to conform to the several tubes 3 andto form bearings for the tubes against the plate.

Each tube 3 isformedof a single piece of sheet metal having a I downwardly extending lug 10 formed; onthe central forward portion thereof and two parallel lugs 11 eX- tending rearwardlyfrom the rearward portion ofthe tube in spaced relation to each other and in spaced relation to the top and the bottom of the tube. The rear plate 9 of the frame structure has a forwardly pressed, horizontally extending indentation 12 therein; and the lugs 11 of each'tube extend therefrom to the indentation 12 in the rear wall 9. The rearward ends of the lugs 1.1 have shoulders 13 formed thereon which engage the indentationof the rear wall 9, and the lugs 11,. have lips or projections 14 which extend rearwardly from the shoulders 13 through openings in the wall 9 and the rearward surface of the wall 9 within the indentation 12 therein to connect the lugs 11 to the wall9. V

The downwardly extending lug 10 of each tube 3 is provided with shoulders 15 spaced below the bottom of the tube a distance equal to or slightly in excess ofthe thickness of the coins adapted to be carried by the tube, and the shoulders 15 engage the top of the base late 8 tc-retain the bet-tom f the tube in the proper spaced relation tothe top of the plate 8. Each lug is provided with-a lip or projection 16 which extends downwardly member to stiffen the tubes and the tubes to stiffen the frame member. The base plate 8 is providedwith coin discharging openings 17, one for each tube 3, which correspond in size with the interiors of their respective tubes, and whichhave their centers located rearwardly of-the centers of their respective tubes. These openings 17 are each provided'with a coin interruptingpart or shelf 18 which is formed integral with the base plate 8. Eachpart or shelf 18 extends below the level of the body of theplate 18 and beneath the rearward portion of its opening 17 in close proximity thereto; and each part or shelf 18 is constructed to be encountered by therearwardportion or side of each coin discharged through its opening. 17, during its descent therefrom, for a purpose hereinafter explained.

The base plate8 forms a support for stacks of coins within the tubes 8. The stacksof coins rest upon the base plate 8 and the lowermost coin of each stack is free to be moved rearwardly over the plate 8 and beneath its tube 3, and the coins above it to the discharge opening 17 back of the tube. When the bottom coin of a stack is thusmoved rearwardl the coins above it are prevented from moving with it by the rearward wall of the tube 8 containing them. I shallnow describe the mechanism which isoperable to move the coins from the tubes to the discharging openings 17, one such mechanism being provided for each tube.

Slidable on the base plate 8 and beneath the tubes 3 are coin ejectors.19 one for each tube, and each comprising a bottom part or plate I 20 havin a coinreceiviiw openin 21 therein *1 t: a b 7 a top part 22spaced above and extending over the bottom plate 20 and a rear'part 23 connecting the top and bottom parts 20, and 22,

allbeing formed .of a single piece of sheet metal, as clearly-shown in Fig. 11.

Theseejectors 19are adapted to slide reare wardly and forwardly on the base plate 8 and the sides of the bottom-plates 20 of the ejectors are guided by andbetween walls which project upwardlyfrom the'base plate 8 and which are formedintegraltherewith. The

' walls which guidethe outer sides of the end ejector plates 20 ar'e formed by upturned anges 24 on the ends of the base plate 8, and

the walls which guide the inner sides of the endejector plates20 andthesidesof the intubes 3 and projecting outwardly from the the sides ofthe ejector plates 20.

Each ejector plate 20 rests normally'in the forward position with its opening 21 in registry withthe tube 3 above it to receive a coin tierefroin, as shown full lines in Fig. 5, and when it is moved to this position its further forward movement is stopped by the top part 22 of'the ejector engaging the back of its coin tube 3. v

l The forward end. portionofeach ejector plate 20 is cut out, at 27, to permit each plate 20 to clear the connecting lug 10 of its tube 3 when the plate 20 is moved rearwardly to the position shown by dot-and-dash lines in Fig. 5; and the width of theopening 27 of each plate is less than the diameter of the coinsto be ejected by the plate, so that, when each ejector. plate 20 is moved rearwardly from the position shown by full lines to the posisides of the lower ends thereof directly above tion shown by dot-anddash lines in Fig. 5,.

it will move the coin resting within its open- 21 from its tube 3 to and discharge it through the discharging opening 17 back of its tube. v

The coin ejectors 19 are'adapted to be operated by levers 28, one for each ejector. Each lever 28 is formed of asingle piece of sheet metal, as clearly shown in Fig. 10, comprising two spaced ejectoroperating arms or members 29 connected by apart 80, and a hand operated arm 81 projecting forwardly from one of the ejector operating arms 29.

The upper end portions of the arms 29 of the levers 28 are fulcrumedon pins 32 which extend through the same and through the lugs 11 of the coin tubes3, one lever 28 being fulcrumed on the-lugs 11 of each tube, and the lower end portions of the arms 29. of each lever 28 extend into openings 33. in the top part 22 of the underlying coin ejector 19. The handoperated arm 31 of each lever 28 extends around one side of its coin tube 3 with its forward free end portion terminating in a convenient position to receive the thumb of the person using the device when it is in service. 7

Each coin ejector 19 is'pressed normally forward with its top' part 22 engaging the back of its coin tube 3, by a bifurcated spring 34 formed of a single piece of flat, resilient metal and constructed as clearly shown in Fig. 12, and comprising a horizontal top plate or part 35 and two spaced, parallel arms 36 extending downwardly therefrom. The connecting member or-plate'35 of each spring 84 engages the lower surface of the upper frame plate 7 and it is'secured thereto by meansof a securingpart or strip of metal over the same as shown in Fig. 5.

.37 Eigs.{ 1{and 5.) .whichextends around the bottom of the plate 35 and embracesthe same and has its end portions extended'up through openings in. the top frame I plate .7 and bent The top plate 35 of each spring 34Lis provided with a projection 38 which extends up through the top frame plate -.7 and is-bent overthe same with; one end portion of itsconnecting part on stripfiil The lower end portions of the spring. arms-:36bear against the backs, of the lower .end portions'of the side arms ormemv bersj 29 of the 'operating levers 28'to restore them-and their coin ejectors 19 to the normal position shown by full lines in Fig. 5, after theyhave beenmoved therefrom and; released by the depression and release of the hand op eratedarms 31 of the levers 28.

. Itwill now be understood that ifcoins be placed within each-tube 3 the stacks ofcoins will resttherein-supported by the base plate Swith the lowermost coins of the stacks within the openings- 21 of the coinejectors, and

thateach timea hand operatedarm 31 is depressed thelowermost coin within the tube 3 governed by the armwill be ejected from the device. by being moved} rearwardly beneath the tube. to and discharged by gravity 1 through the opening 17 ingthehb aseplate 8 rearwardly of the tube 3..

During the-operation of the change maker, the personusing thesame places his right hand infront of the device with the fingers thereof extending beneath the discharge opening 17 of thetube 3'from which he desires a com or coins, and he depresses the lever arm 31 for that tube with the thumb of the same hand, and each time he depresses the lever arm 31 a coin isidisch'argedfrom the opening 17 and intohis hand; As each coin falls. from the discharge opening 17; the rearWa-rdfpon tion or side of the'coin encounters the coin interrupting part or shelf 18. beneaththe rear ward part of theopenin'g 17,"therebycausing the forward portion ofjeach coinlto descend in advance of the rearwardportionthereof.

Each coin interrupting part or shelf 18 is so constructed and related to its coin dischar in o enin' l7 that it not. 0111 causes the forward portions of the coins falling from the opening to descend in advanceof the rearwardportions. thereof but also to invert the coins and cause them to .fall substan tially' through a vertical path down into the hand of the user of the device and tostack the coins oneupon another in the hand of the user. In Fig; 5, I haveshown by dot anddash lines several positions assumed by a coin during its descent from a. discharge opening 17 to the hand of a user ofthedevice.

I have discovered that. this method of ejecting coins 'fro'm'a change maker not only lessens the liability of accidentally; dropping coinsv from the hand of v the user but also increases, the speed. offmaking change and lessens the'time heretoforerequired to ac.-

quire proficiency in using-achange maker. The rear. plate 9 of the frame member 215 Whichare located the vertical members or parts 41 of hooks 42 as a means of pivotally" connecting the hooks t'o theendsof the frame structure ofthe. change maker; The hooks 42 are providedas a suitable means of attaching the device to the belt or other part of the wearing apparel of the user thereof.

Theloc'ationof the ears or projections .14 of the connectinglugs 11 ofthe tubes 3, within thedepression 12 in, the rear plate 9 of the frame structure protects theclothinglof the user of the device from the otherwise wearing effect of the ears-or projections 0nthe clothing; I 7

I Each tube 3 is provided with a suitable re movable cap or cover L3 havinga top providedwith a slot 44 through-which coins may be inserted into the tube, and provided; also with a sleeve 45 surrounding .the tube 3 and provided with an opening e6 therein to receive a projection 47 formed onthetube to prevent accidentaldisplacement of the cap from the tube. When it is desired to remove the cap from the-tube, the tube orcap or. both .may be sprung from normal condition to free portion of which is located between an arm- 29 of the leveranol the adjacent lug 11 of the coin tube and theother end portion-of which is bent around to engage .a head on one end of the pin- 82. By. bending the 1'? part 49 from,engagement-with the head 50 the pin 32 may thereafter be withdrawn from i the lever arms 29 and the lugs 11 for the re moval ofthe lever. The lever arms 29 of each lever 28, embrace the two tube lugs 11 on which the lever is fulcrumed, thereby: pre venting lateral displacement of. the levers.
