VENDINGMACHINE.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed November 5, 1910. Serial No. 590,889.

that class of vending machines in4 which articles are fed from the machine in the form of a strip which, if desired, may be divided into tickets or checks, such as stamps, soda checks, or predetermined lengths of strips having any desired identifying characters thereon, although. as is apparent, my novel device may be readily adapted to feed any desired article into a position accessible to the intending purchaser. l

My invention consists of a novel construction of a vending machine wherein novel means are employed for feeding the stamps, novel means for locking the feeding mechanism in inoperative position and novel means for preventing the purchaser from obtaining more than the predetermined number of stamps for the money which has been inserted in the machine.

It further consists of a 'novel construction of a vending machine which may be readily operated to vend stamps of any desired denomination.

It further consists of a novel construction of a detent.

It further consists of a novel construction of a feeding device for the stamps.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings a preferred form thereof, since this embodiment hasbeen found in actual, practical use to give very satisfactory and reliable results, although it is of course to be understood that the various instrunentalities of which my invention consists can be variously arranged and organized and that my invention is not limited tothe precise arrangement and organization of these instrumentalities as herein shown and described.

Referring to thedrawings, l designates a housing frame or casing adapted to carry the various mechanisms which cooperate to cause the stamp or article to be delivered into a position accessible to the purchaser upon the insertion in the machine of a coin or check of proper dimensions. The housing or casing 1 is secured in position in any desired manner and, in the present instance, I have shown the base portion thereof as being provided with the apertures 2, yas shown in Fig. 1, which are adapted to yreceive suitable fastening devices, it being understood that a suitable cover is provided in which the housing or casing 1 is inclosed and in practice a portion thereof, such as for example, the top portion, is preferably constructed of transparent material.

Any desired type of coin mechanism may be employed but for the purpose of illustrating one type of such mechanism, I have preferred to show a construction such as is described and broadly claimed in my former patent for fraud preventative device, No. 852,111, granted April 30, 1907. f

3 designates the inlet opening for the coin or check of dimensions the size of which will vary in accordance with the dimensions of the check or coin which is to be used to 7 the pivoted side 6 being normally maintained in its closed position by means of a spring 8, one end of which is suitably secured to a fixed point while the other end thereof bears against the pivoted side 6. The lower inner edge of the pivoted member 6 is suitably beveled as at 9, in order to form a V-shaped groove at the bottom of the coin slot, the upper end of the slot being provided with a longitudinally extending groove 10 so that when a coin of proper dimensions has been inserted in the inlet opening 3, it will pass directly through the coin slot into one of the slots 11 of coin wheel 12, which latter is fixedly secured on a shaft 13 suitably mounted in the housing 1.

The slots 11 are preferably angularly inclined and the outer face of the coin wheel 12 in proximity to the slots 11 is suitably recessed, as indicated at 14, thereby adapting the same to receive the stop or detent 15, the forward end of which extends into said recess or seat and is normally maintained. therein owing to the manner in which the same is mounted and, in the present instance, I secure the stop 15 to t-he free end of the resilient member 16, the opposite end of which, as most clearly seen in Fig. 7, is secured by means of a suitable fastening device 17 to the housing 1.

In case the machine is to be operated with two coins, I preferably employ a detent or stop such as is indicated in Fig. 8, wherein it will be seen that the forward end thereof is provided with a beveled face 18 which at one end extends completely to the end of the stop, while at the other end thereof it terminates in the shoulder 19, so that two coins will operate the machine. In case the machine is to be operated with a single coin, I employ a detent or stop, such as is seen in Fig. 9, wherein simply a beveled face 20 is employed, which will permit one coin to operate the machine.

In order to operate the machine I provide a manually actuated handle 21 which is carried by a shaft 22 suitably journaled in the housing 1 and the end of the shaft has suitably connected therewith a gear 23, and, in the present instance, I have shown this as consisting of a bevel gear, the same being adapted to mesh with a gear 24 loosely mounted on the shaft 13, as is best seen in Fig. 12. The gear 24 is suitably apertured to receive a container 25 having any desired contour but shown, in the present instance, as cylindrical, said container being adapted to pass through the apertured gear 24 and be secured therein in any desired manner. The container 25 has located therein a spring 26 one end of which abuts against an adjustable stop 27, the other end thereof engaging a plunger 28, the forward end of which is suitably rounded, thereby adapting the same to be seated in the recesses 29, the number of the same preferably corresponding to the number of slots 11 in the com wheel 12. The gear 23 will thus be fric",

tionally connected with the coin wheel 12, so that when the coin wheel. 12 is released the gear 23 and coin wheel 12 may revolve in unison. The cylinder 25, in the present instance, passes through the apertured disk 30, which, if desired, may be integral with the gear 24, as is apparent, but for convenience of manufacture the same is shown as being a separate disk secured thereto by fastening devices 31. The disk 30 near its outer periphery is provided with the cams 32. rlhe shaft 13 has also mounted thereon a sprocket wheel 33 around which passes a sprocket chain'34, said sprocket chain also passing around a sprocket wheel 35 rotatably mounted in the housing 1. Certain of the links of the sprocket chain 34 are formed by or provided with the feeding members 36 which, in the present instance, consist of a plate deflected to form the sides 37 and 38 which are suitably apertured in order to adapt them to be secured with respect to the links of the sprocket chain, the sides being connected by a top portion 39 which is provided with a desired number of upwardly extending members 40, it being apparent that the number and contour of such members may vary in accordance with the varying conditions met with in practice.

41 designates a reel mounted in the housing 1 and adapted to carry a strip 42 which is suitably scored, weakened, apertured or slotted and in the strip which I have illustrated the same is perforated as is indicated at 43 and provided with the slotted portions 44 although, as is evident, the character of the perforations or slots is immaterial in so far as the working of the machine is concerned. rIhe strip 42 passes over a roller 45 mounted in a guide 46 which is carried by or forms a part of the housing 1. The guide 46 is provided with the guide members 47 on which the strip 42 travels, said guide members having an opening therebetween through which travels the sprocket chain 34, t-he parts being arranged in such a manner that the feeding members 40 will extend above the upper surface of the guide members 47. The guide members 47 at their rear end are curved downwardly in order that the feed or contact members 40 will coact with the perforations 43 or 44 at the proper time, it being noted that the forward end of the guide members 47 terminate in proximity to the sprocket wheel 35. If desired, the guide 46 may be provided with the stationary vtable 48 or equivalent means to cause the upper stretch of the sprocket chain 34 to travel in substantially the same horizontal plane.

49 designates a tension member which con- ISU sists of the cross bars 50 adapted to be seated on'athe upper portion of the guide 46 and one of said bars is suitably recessed, as indicated at 51, in order that they may be placed in position without necessitating the complete removal of the screws 52 which maintain the tension device in assembled position. The cross bars 50 have secured there* to the longitudinally extending bars 53 in such a manner that there is a space between said bars 53 and the bottom guides 47 for the strip 42 to freely pass. The forward ends of the strips 53 are resilient 'and preferably deiected slightly downwardly as best seen at 54. The sides of the sprocket wheel 35 are provided with the cams 55 which travel in the path of the spring arms 54, as will be best understood by reference to Figs. 2 and 3. The forward end of the guide for the strip 42 is preferably provided on each side with the ledge 56 which forms a continuation of the bottom guide member 47, in order that the stamp will be accurately guided to a position accessible to the purchaser.

In order to positively prevent the rearward feed of the shaft 13 4the latter has mounted thereon a ratchet 57 with which coacts the free end of a spring 58, the opposite end of which is suitably fixed to the housing, so that the strip may be only fed in a forward direction.

The shaft 22 has mounted thereon a disk 59 which carries a cam member 60 provided with the reversely inclined cam faces 61, as seen in Fig. 11, said cam faces coacting with the roller 62 mounted on the movable member 6 of the coin slot, so that when the lever is actuated in either direction the coin slot will be opened in order to permit any coin, check or counterfeit thereof which has been retained in the coin chute, to drop therefrom into the return passage 63 which will deliver such coin, check, or counterfeit thereof to a position accessible to the purchaser.

The size of the coin slot is adjusted by means of the screw 64 which controls the relative position of the pivoted member 6 in relation to the stationary side 5.

Located beneath the coin wheel 12 is a coin guide 65 whereby the coin or coins in the coin wheel will be carried around with the coin wheel and exposed to view and finally be discharged into the bottom of the device or a suitable coin container therein.

The operation will now be readily apparent and is as follows :The reel 41 is provided with a strip 42 which is passed over the roller 45 and thence over the bottom guides 47 and beneath the longitudinal bars 53 so that the end of the strip will be held in position between the resilient end 54 of the. member 53, and the cams 55 on the sprocket wheel 35. The coin slot is now adjusted by means of the set screw 64 so that only a coin of predetermined size will pass therethrough. Having the parts thus adjusted, the machine is ready to be operated. When one or more coins are passed through the coin inlet 3, if they are of the proper dimensions, they will pass comA pletely through the coin slot and be received in one of the slots 11 in the coin wheel 12, as indicated in Fig. 10, and abut against the detent or stop 15 which closes one side of such slot 11. The handle 21 is now rotated to the right, whereupon the gear 24 will be rotated, thereby causing the cam 32 to co-act with the coin and cause the stop or detent 15 to be moved out of its engagement with the seat 14, whereupon the gear 24 and the coin wheel 12 are rotated in unison until the detentor stop 15 comes into engagement with the next successive recess or seat 14 in such coin wheel 12. As the coin wheel 12 is frictionally connected with the gear 24, as soon as the detent or stop 15 moves out of engagement with the coin wheel, the shaft 13 will be rotated, thereby rotating the sprocket wheel 33 `and causing the sprocket chain 34 carried thereby to travel a predetermined distance. The feed members 40 are preferably arranged so that they will contact with the perforations in the strip 42 and, in the present instance, they are arranged so that they will pass through the slots 44 and cause thestrip 42 to be positively fed forwardly, the parts being so arranged that if a stamp or check strip is in the machine when a single stamp or a desired number of stamps have been fed into such a position as to be readily removed from the machine, one of the cams 55 has been moved into the position seen in Fig. 3, in which position the stamp strip is securely held between a cam 55 and the resilient members 54, the end of the stamp strip being at this time exterior of the machine, as indicated in Fig. 5, whereupon when the purchaser pulls on the strip the same will become detached, so that it may be withdrawn from the machine. As soon as the cam 55 passes beyond the resilient strips 54 the same will be relieved from tension and the stamp strip will again be fed forwardly upon the introduction of a proper coin.

In the present instance I have shown the coin wheel as provided with five coin slots, the relation between the parts being such that while the coin wheel 12 is provided with five coin slots, the sprocket wheel 35 is provided with eight teeth while the sprocket wheel 33 is provided with twenty teeth. In the construction which I have sho-wn for thepurpose of illustrating my invent-ion, the slots in the coin wheel are adapted to receive two coins but the pe- :sol

riphery of only one of these coins will eX- tend beyond the side of the coin wheel sufciently to coperate with one of the cam members 32, as seen in Fig. 10.

Particular attention is directed to the fact that in my present construction I have rendered practically all of the movement positive and have eliminated the necessity of employing a large number of springs, it being noted that the only springs employed are the spring S for maintaining the coin slot normally closed, the spring 16 which carries the detent and the spring pressed plunger which causes the frictional engagement between the gear 24 and the coin Wheel 12 as will be readily understood by reference to Fig. 12 of the drawings. Part-icular attention is also directed to the novel manner in which the strip of tickets or other device is positively fed so that a predetermined length of the strip is uniformly fed under all conditions which arise from practice. It is also to be noted that I have devised a device which is practically fool proof, since the handle 21 may be manipulated in either direction without any liability of the operating parts becoming strained or distorted, and there can be n0 undue strain on the working parts owing to the manner in which the coin wheel is frictionally connected with the driving mechanism.

In the present instance I have shown the cams 32 as corresponding in number to the number of coin slots, but the number of cams which are employed is immaterial since the only difference in the operation, in case one or more cams are employed, is that a shorter revolution of the actuating handle 21 is necessary when a larger number of cams are used.

In practice a number of machines constructed in accordance with my invention may be placed in a single ease so that if it is desired to vend articles such as stamps of various denominations, this may be accomplished and as hereinbefore pointed out, my present type of machine may be readily adapted for the feeding of any predetermined length of strip or readily adapted to be operated by any desired type of coin, check or other element with which it is desirable to have the coin mechanism coperate.

Since a number of links of the upper stretch of the sprocket chain travel in substantially the same horizontal plane, the contacts or feeding members will simultaneously engage a number of independent tickets so that a positive feed is eected and it will be impossible to tear off more than the ticket or tickets, in payment of which the proper coin or check has been inserted to work the machine.

-In order to illustrate one manner of forming the feeding or contact members, I have shown the same as being connected with certain of the links, but in actual practice the Contact or feeding members preferably constitute in themselves links of the sprocket chain and as is apparent these feeding members may be spaced any predetermined distance apart.

My present machine may be readily adapted to sell a single one cent stamp, a single two cent stamp, five two or five one cent stamps or any other desired number of stamps or tickets.

The coin wheel disclosed herein is similar in some respects to that seen in my former patent for coin wheel, No. 864,527, granted August 27, 1907, wherein I have described and broadly claimed such type of coin wheel.

It will now be apparent that I have devised a novel and useful construction of a vending machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacricing any of its advantages.
