COIN-CONTROLLED VENDING-MACHINE.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed fi ber 28, 1906. Serial No. 284,868.

To all whom it may concern.-

Be it known that I, FRANK J. Rowsn, a citizen of the United States, residing at Pawtucket, in the county. of Providence and State of Rhode Island, have invented certain new and useful Improvements in Coin-Com trolled Vending-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Like reference numerals indicate like parts.

Figure 1 is a view of my improved vendingmachine as seen partly in top plan and partly in section on line 1) o of Fig. 2. Fig. 2 is a View of the same as seen partly in elevation and partly in section on line ac 9c of Fig. 1. Fig. 3 is a view as seen partly in elevation and partly in section. on line y y of Fig. 2. Fig. 4 is a view as seen partly in elevation and partly in section on line .2 z of Fig; 2. Fig. 5 is a side elevation of my said machine. Fig. 6 shows in side elevation the coin, coincarrier, and rocking cam when the coin is engaged inposition and also the driving-lever operated by said cam. Fig. 7 shows in side elevation the same parts as Fig. 6 at the time when the coin is released from the coin-can rier. Fig. 8 is a perspective view of the case and exterior portions of said machine.

, My invention relates to the class of coincontrolled vending-machines; and it consists.

of the novel construction and combination of the several parts or elements as hereinafter. described, and specifically set forth in the claim.

'-The case inclosing the operative parts of the mechanism consists of the base 1, the front 2,-the back and the two side pieces 3. It has a cover 4,- secured by hinges 5 to the upper end of the back piece. The cover 4 is fastened by means of a hasp 6 and padlock 7 or in any other suitable manner. A drawer 8 is provided at the bottom of the case and'is secured by alock 9. A sideportion or plate 10 of the'frame, which supports the opera-' tive mechanism, extends through the case and is flush with the side piece 3. The plate 10 has a coin-aperture 11 through it. The crank-shaft 12 is rotatably mounted-in the side plates 10 and 13 of the frame, and on the end of said shaft which projects out beyond the plate 10 a crank 14 is fastened, by which said shaft 12 may be rocked. Thestop-pins 15 16 limit the extent of the movement of the crank 14. The shaft 12 has a coin-carrier 1 fastened thereon which has an oscillating Figs. 1 and 3.

on the shaft 12.

movement with the shaft 12 when the crank 14 is turned in the arc of a circle as limited by the stop- pins 15 and 16. This carrier consists of two side plates 17 17 and a front plate 18. The front plate 18 has a vertical slot 19, as seen in Figs. 1, 2, 3, and 5. On each side plate 17 is a sleeve or tubular bearing 20, which is fastened by a rivet or set-screw on the shaft 12. A coin-chute 21 is fastened to the top of the front plate 18 and an opening therein registers with the coin-aperture 11 of the plate 10. At the lower corners of the coin-chute 21. are the coin-rests 24 24'for the coin 23. A spring 25 is fastened at one end to an eye or lug 22 in the upper portion of one of the side plates 17 and at its opposite end to the stud 26, which projects from the frame.

This spring normally holds the coin-carrier inthe position illustrated in Fig. 2 and keeps the crank 14 in contact with the stop-pin 15 when the machine is not in operation. A

coin-ejector 27 extends in a bracket form from the inner side of the plate 10 of the frame, as shown in Fig. 3, and is in alinem'ent' with the slot 19 of the front plate 18 of the coin-carrier. Up to this point the coin mechanism is the same as that shown. in Letters Patent of the United States No. 764,67 9, dated July 12, 1904, and issued to me for improvements. in coin mechanism for vendingmachines.

A tubular sleeve 28 surrounds the shaft 12 and turns with it, being held firmly thereon by means of the set-screw 29. A toe 30 extends from the sleeve or tube 28, as seen in A rocking cam 31 has a tubular bearing 32, by which it is loosely mounted This cam 31 is a sectorshaped plate, having a flange 33, Whose edge is curved, as best shown in Fig. 3, to form aworking or cam surface.- The plate has a stop-pin 34 at its upper corner and a slot, as seen in Figs. 2 and 6. the tubular bearing 32 of the rocking cam 31.

A rock-shaft 36 is loosely mounted in the frame, as shown at 37 37. A sleeve or hub A toe 35 extends from 38 is fastened on the rock-shaft 36 by a setscrew 39, and a driving-lever 40 extends from the sleeve or hub 38. 'The driving-lever 40 has a pin41 at its upper end, which normally is held in contact with the stop-pin 34 of the rocking cam 31 by force of the spring 42-, said spring being fastened at one end toa' lug 43 of the driving-lever 40 and at the opposite end to a lug 44, extending from theframe s .Another sleeve or hub 45 is fastened on the" rock-shaft 36 by the set-screw 46 and carries a detaining-lever 47, whose upper end is opposite end to the lug 50 from the frame. Two other sleeves or hubs 51 52 are fastened on the rock-shaft 36 by the set-screws 53 These sleeves or hubs 51 52 have the deliverylevers 55 56, which at their upper ends project outwardly, as shown at 57 58. At these bent ends 57 58 are flanges 59 60, extending at right angles and directed toward each other. At the upper ends of the deliverylevers 55 56 are the L-shaped inwardly-directed bends 61, 61 62, and '62. Two brackets or shelves 63 64 are secured to the frame of the machine and extend inwardly, as shown in Figs. 1, 3, and 5. Amagazine or chute 65 contains the articles which are to be delivered, those shown in the drawings being tubes 66, containing a towel 67, and they fit said magazine or chute 65 loosely and are adapted to drop therein by gravity. A piece of soap '68 is shown wrapped up in the towel 67. o The operation of my improved vendingmachine is as follows: The machine must be set up perpendicularly, as illustrated in Fig. 8, because the force of gravity is utilized in the insertion and delivery of the rolls or packages '67 and in the insertion and ejection of the coin. Suppose the magazine 65 is supplied with a number of rolls or packages 66. These lie one upon another in a vertical pile between the flanges of the magazine or chute 65, the lowest one 'of the series resting, as seen in Figs. 2 and 3, upon the top edges of the bent ends 61 and 62 of the deliverylevers 55 and 56.- This is the inoperative position of the machine, the crank 14 being held in contact with the stop-pin 15 by means of the spring 25. I will first explain the movement of the mechanism when there is no coin in position within the machine. An oscillation of the crank 14 from the stop-pin 15 to the stoppin 16 will under those conditions have no effect whatever upon the rocking cam 31, but will have its only effect upon the coin-carrier 17, which is fastened on the shaft 12, the toe remaining in its normal position the meanwhile. When a coin 23 is inserted through the slot or coin-aperture 11,it enters the coinchute 21 and slides by gravity down along the inclined. plate 18 till it comes to the coinrests 24 24, by which it is temporarily supported in position, as illustrated in Figs. 1 and 2. As the coin-carrier 17 is oscillated by the crank 14 in the direction indicated by the arrow 70 in Fig. 2, the sharp point of the toe 35 comes into forcible contact with thecoin 23, and then the continuing movement of the coin-carrier 17 causes the coin 23 to press against and move the toe 35, and so imparts movement from the coin-carrier 17 to the rocking cam 31, because said toe and rocking cam are fastened together and both are loosely mounted on the shaft 12. As soon as the rocking cam 31 begins to oscillate 0n the shaft 12 in the direction indicated by the arrow 71 in Fig. '6 the stop-pin 34 clears the pin 41 of the driving-lever 40. The pin 41 by the movement of the rocking cam 31 is presently engaged by the curved cam edge of the flange 33 and is pressed downward by said cam edge. in this way the driving-lever is moved-, and so rocks therock-shaft 36, to which the hub 38 of the driving-lever 40 is fastened. At the same time this osci llation of the rock-shaft 36 causes a like movement of the detaining-lever 47 whose hub is fastened on said shaft. The detaininglever 47 stands slightly in advance of the drivingdever 46, as's'eein in Figs. 3 and '5, and whereas in its normal position the detaininglever 47 by its U-shaped slot (shown in Fig. 3) loosel receives the toe so through said slot said 'detainih leve'r iq by its oscillatory movement just described comes into the position illustrated. Fig. 5 and allows the toe 30 (which by the'movement of the crank shaft 12 has risen from the position shownin Fig-I3 to the position shown in Fig. 5) to he received into the concave seat of the detaining-lever 47, as seen in Fig. 5. Dining the continuance 'thereatter of the "oscillation of the rocking "cam 31 said too 30 is supported on the detaining-lever 47 in the eoneave seat 48 thereof, and although the detain-ing lever 47 continues its oscillatory movement it engages slidingly the toe 36-. Thus the engagement of the toe 30 with the seat 48 of the detainin -lever 47, so long assaid engage ment oontinues prevents any return'movemerit of the rocking cam '31 by the spring 25. At the same time the rook-ing "of the shaft 36 causes the delivery lev'e'rs 5'6 '(whose'hubs 51 52 are fastened on the shaft 36) to move inwardly in the direction indicated by the arrows 72 in Figs. 3 and 5. During the time of this inward movement of the delivery-levers 5'5 '56 the lowermost roll 66 issnpporte'd on the top edges of the bent ends 61 and 62, but when this inward movement of the delivery-levers 55 56 has proceeded till said levers are in the position indicated by dotted lines in Fig. 5 the lowermost ro'll'66, being no longer'su' ported,falls by gravity into the position indicated by dotted lines 66 In this 'osition the lowermost roll rests on the she ves 63 64, but is prevented from. rolling off by the bent forward ends 59 60 of the projections 57 '58 of the delivery levers 55 56. This displacement of the lowermost roll 66 "from t e position shown in solid lines in Fig. 5 to the position shown 'at 66 in dotted lines in said figure causes the next higher roll in the chute to descend by gravity to the position indicated in said figure by the dotted lines 66 In these movements o'f'the several parts of the mechanism above explained the springs have been put under increasing tensionnamely, the spring of the coin-carrier 17, the spring 42 of the driving-lever 40, and the spring 49 of the detaining-lever 47 These springs when released operate with considerable force. This release occurs when the tip end of the toe is, by the oscillation of the rockingcam 31, carried to the point where it no longer is engaged in the seat 48 of the detaininglever 47. Then the delivery-levers 55 56, the levers and 47, the rocking cam 31, coin-carrier 17, and crank 14 all return to their normal positions. As in the normal position the projections 57 58 of the deliverylevers 55 56 extend outwardly from the case and the roll 66 is no longer supported by them, but has been swept oil the shelves 63 64 by the portions ,61 62" of the deliverylevers 55 56, said roll is ejected forcibly by the springs and descends to the shelf 73, Fig. 8, where it can be taken by the purchaser, as shown at 66. In these return movements the pin 41 of the driving-lever 40 comes again into contact with the stop-pin 34. When thecrank 14 has come to the position shown in Fig. 7, the coin-carrier comes to the position shown in said figure, and the coinejector 27 then extends into the lower portionof the slot 19 of the plate 18 of the coincarrier 17. The coin-ejector 27 then comes into contact with the lower edge of the coin 23 between the two coin-rests 24 24. The continuing oscillatory movement of the coincarrier causes said coin-ejector 27 (which is stationary) to force upward the coin 23. Thus the coin 23 is dislodged from the coinrests 24 24 and being no longer supported falls by gravity, as illustrated at 23 and so falls into the drawer 8. In case a washer is deposited in the coin-chute 21 instead of a coin it descends and is seated on the coinrests 24 24 and is pushed therefrom by the toe 35 just like a coin; but when the sharp point of the toe 35 rises from the shown in Fig. 2 to the position shown in Fig.

. 6 it passes freely through the hole of the washer and so the Washer cannot press the toe 35 inwardly, and thereby move the rocking cam 31. Consequently the machine does position I not operate, and when the crank 14 returns to the pins 15 the washer, being then dislodged from the coin-rests 24 24 by the coinejector 27, drops into the drawer. So, too I when a pasteboard disk is inserted in the coin-chute instead of a coin the second position of the toe 35 punctures the pasteboard disk, because it has not sufficient strength to move said toe and rocking cam as a coin has, and thus the machine remains inoperative and the disk is cleared away by the coinejector 27 and drops into the drawer.

I claim as a novel and useful invention and desire to secure by Letters Patent- In a machine of the class described, the combination of a frame, two pivotallymounted delivery-levers each having a forwardly-extending projection with an inwardly-directed bent flange, the distance between said projections being greater than the length of the article to be vended and the distance between the inward ends of said flanges being less than the length of said article, said levers also each having a rearwardlyextend ing L-shaped projection the innermost ends of which are distant from each other a space less than the length of said article, a magazine-chute supported by the frame and adapted to contain said articles and having an open bottom, a shelf on said frame and located beneath the open bottom of the chute, the said rearwardly-extending projections of the said delivery-levers being adapted to su port the lowermost of the said articles in t e chute when the' machine is inoperative, means adapted to give the delivery-levers an inward oscillation whereby said rearwardlyextending projections of the delivery-levers move out of contact with the lowermost of said articles and allow said articles to drop to the shelf, and means adapted to give a forward oscillation. to said delivery-levers whereby said article on the shelf is thrown from said shelf. v

In testimony whereof I aflix my signature in presence of two witnesses.
