DISPENSING MACE-ZINE.

Application filed August 13, 1924.

My invention relates to dispensing machines, and more particularly to a dispensing machine in which a variety of articles can be placed for sale, with means for automatically discharging one of said articles from the machine when the purchase price has been deposited in the machine, but the principal object of my invention is to provide a machine in which a variety of articles of various prices can be placed and into which the required number of coins can be putto make up the purchase price of the article desired and when the last of said coins has been deposited in its proper slot, the machine will automatically operate to discharge the article of that price. For example, if it is desired to secure from the machine an article the price of which is forty-two cents, the'purchaser will deposit a twenty-five cent piece, a ten cent piece, a five cent piece and two one cent pieces, male ing up a total of forty-two cents, each de nomination of coin being deposited in a different coin receiving slot. When the lastof the coins is deposited, no matter which itmay be, making the required purchase price of thatparticular article, the machine will be actuated and the article discharged from the machine. Y

Another object of my invention is to provide in a mac-hine of the character referred to means whereby when a mistake has been made in depositing the coins, or if the pocket in which the desired article is supposed to be is empty, or other reason why the article cannot be delivered, themoney deposited can be returned to the purchaser who has attempted to work the machine.

Another object of my invention is to provide a machine with a series of articlereceiving pockets or chambers adapted to he turned to bring the pocket or chamber containing the desired article around to the discharging position, which automatically relates it to the controlling mechanism so that when the coins have been deposited to make up the purchase price, the desired article will be discharged from the machine Another object of my invention is to pro vide in machine of the character referred to simple setting means for controlling the electrical circuits, or connections, thus mak ing it possible to easily and quickly set the machine to operate on a great variety of different priced articles.

My invention as embodied in the machine illustrated on the accompanying drawings for descriptive purposes may be considered as being built to contain packages of cigarettes. the different priced cigarettes being placed in the different vertical pockets or receiving chambers of the machine. I will now describe the machine illustrated on the drawings. lhe machine is of box-like form, having the base, 1, of'substantially square form, with four corner posts, 2, 2, and the top 3, as seen in Figs. 1, 2 and 7. Rotatahly mounted in said machine is a container 4, shown to be round, and having arranged view therein a series of vertical pockets, or package-receiving chambers, as 5, sixteen of these being shown, as will be clear from Fig. 1, each having a glass front, as 6. Said container has a floor 7, from which extends downwardly a central pedestal or stem, 8. The pockets. or chambers, 5, have floors, with holes, 5", therethrough, as seen in Fig. 2. Packages of cigarettes, C, are shown in place in said pockets. In each pocket, above the packages 0. is a follower, 9, having a stem 9, adapted, when the last package 0 has been discharged from a pocket, to pass through the hole 5 through the floor 5 of the pocket, as will be clear from Fig. 2, for a purpose hereinafter again referred to. The

container cover, designated 10,,is provided with a central pin 11, having a bearing in the top 3, as shown in Fig. 2. Thus it will be seen that said container can be rotated to bring any pocket, or vertical tier of packages to the front, or discharging position, and in register with a discharge spout, designated 12.

Referring to Figs. 2 and 6, and 8, there is mounted on the pedestal or stem 8, a series of contact fingers, as 13, there being eight rings and each ring having sixteen of the contact fingers 13, as shown in 6. Said fingers normally project outwardly, but can be swung inwardly, as shown, for a purpose again referred to. Mounted in the base or box portion of the machine, as on a support, 14, and insulated therefrom in any suitable manner, is a series of eight pair of terminal spring elements, as 15, adapted to receive therebetween the fingers 13, when said fingers are out and said container and its stem 8 are turned. It will be seen that there are eight pairs of terminal spring elements 15, and eight rings of fingers, oppositely disposed, so that as the 'fingg-ers are turned, it out, they will pass between the spring members of a pair and thus connect them. If the fingers are pressed inwardly, they will not engage with said terminal. elements and will not, therefore, close a circuit from one to the otherof the elements of the pair opposite the finger which is in inoperative position. These spring terminal elements are shown in Fig. 8, which also shows some of them connected with the fingers, 13, and others 'open. The circuit wires to said terminal elements are also shown in Fig. 8. Said circuits include an electro-magnet, 16, adapted, when energized, to attract a lever alr rnature, 17, Fig. '6, the outer end of which "lever is slightly tapered, as at 17, so that as said lever is attracted to said magnet, its outer end will. press by a spring member 18, which acts as a catch and will hold said lever in its moved position, as indicated in dotted lines, Fig. 8, until released in a manner hereinafter referred to. Said lever ar mature is pivotally connected at its opposite end, at 17?. Projecting from the underside of sa'id lever, 17. is a wire finger. 67, as seen in Figs. '2 and 8. An ejector. 20, is 'lslidaloly mounted under the container and 'in position to be moved outwardly through the lower end of the pocket in discharging positionto 'push'the bottom packet from said pocket, as will be clear from Fig. 2. Said ejector 20. is operated by a lever, 21, pivoted at 22, and having its lower end in position to be engaged and moved by the armature lever 17, when the latter is moved by the electromagnet, 'as above described. Thus every time the olectroanagnet 16 is energized, it moves the armature lever 17, which engages and moves the ejector lever 21, and discharges a packet from the pocket in discharging position, said armature lever being caught and retained by the spring member 18, as before described, until released, hereinafter described. The discharged packet falls into the discharge spout, 12, and can be picked up by the purchaser in the well known manner, and as will be clear from Fig. 2.

The electric circuits are controlled by the coins placed in the machine and this is accomplished by establishing certain circuits which require certain coins to complete them before the electro-magnet is energized to operate the ejector mechanism. Referring now to Fig. 1, there are four coin slots showi, designated, respectively, 23, 24:, 25 and 26, designed to receive, respectively, a twenty-five cent piece, a ten cent piece, a nickel. and a one cent piece. The coin, when it reaches the bottom of the coin receptacle, la'idges two terminals and completes a circuit. The ten cent receptacle and the one cent receptacle are provided with contacts so that two ten cent pieces can be placed in the ten cent receptacle and eachwill close a circuit, and four one cent pieces will close four different circuits when four one cent pieces are placed in that receptacle, as illustrated in Fig. 8, in which the coins are indicated in dotted lines. The coin receiving receptacles have means for releasing the coins so they will drop out when desired. In Fig. 4, there is shown a pivoted closure, 27, with an operating Wire 28, therefrom to a lever, 29, pivoted at 30, which closure is between. the bottoms of the one cent receptacle and the live cent receptacle, and there is a similar closure between the bottoms of the ten cent receptacle and the twenty-five cent receptacle, operated by a similar cable or wire, 31., Fig. 6, attached to said operating lever 29, as shown. These two closures can be seen in dotted lines also in Fig. 6. The closure 27, it will be understood supports one side of a nickel in the bottom of receptacle 25, and one side of a one cent piece in the bottom of receptacle '26, while the closure 27*, at the bottom of receptacles 23 and 2-1, supports one side of the twentyfive cent piece and one side of the ten cent piece, and when these two closures are opened by the lever 29.. all four or more coins in said four receptacles will drop out. This operating lever 29 has attached theretan opera-tiny rod, 32, extended out through the front of the machine, Fig. 6. so that it can be pulled by the person who has put in the wrong change, or by one who would have the money returned before the machine operates and discharges the article being purchased. There is also attached to said lever a chain. 33.. which passes around pulley,

34:. and thence back to a pivoted ratchetlilre lever or finger. 35, pivoted at 36, in J. l a

the vase of the machine, with a spring, o7, to normally move SE11 d member to a vertical position. The upper end of said finger is rounded and engages with notches, or recesses, 38, in the bottom of the pedestal 8, so that as said pedestal and the container 4, is turned said finger is moved and released by the notches, 38, thus pulling the trip lever 29, each time said container is turned and automatically opening the coin receptacles.

When said closures 27 and 27 are thus opened, the coins in the coin receptacles will fall outside of the guard strip 39, and into the tray 40, as shown in Fig. 4. When the machine operates in the dischargeof a package, or the article sold, the coins are automatically dropped into the inner tray, 41,

n a manner now to be described. Referring to Fig. 6, the partition members, designated 42, 48 and 44, are stationary, and to these the closure members 2Tand 27 are pivotally attached, as indicated in 4. The end portions and the intermediate portions are movable. These are designated 45. 46, 47 and 48, and are pivoted, as at 49, 5, so that they can be swung rearwardly, and as they form the back wall of the coin-receiving receptacles, it will be evident that the coins therein will be dropped into the inner try, 41. These portions are moved by means of pivoted links, 50, Fig. 5, connected thereto and at their other ends connected to a rock bar, 51, shown also in Figs. 6 and 8. Said rock bar is provided with the vertical arms as 52. there being a link for each of said movable portions and they are moved together.

Referring particularly to Figs. 2 and 8, therev is a pivoted member 53, having a curved portion, as 54. This member is positioned in a bracket, 21*, on'the side of the ejector lever, 21, as clearly shown in Fig. 8, so that when said ejector lever 21 is moved rearwardly by the lever 17, it will operate to raise said member 53, and in so doing it releases the vertical member 52, notched therein, as shown in Figs. 2 and 8, at its upper end and at its lower end said member 52 is secured to said rock bar 51. This permits said rock bar '51 and said vertical member 52, to rock rearwardly. The end of the lever 17 has been moved rearwardly and has caught behind the spring member 18, as referred to and as indicated in dotted lines in Fig. 8. Also secured to said rock bar 51,

near the vertical member 52, is a second vertical member, 58, pivoted thereto as at 59, and provided at its upper end with a rear Wardly projecting arm, 60. This vertical arm 58 is held against moving laterally by means of a spring hook, 61, secured to a block 62. on said rock bar 51, with its hook around the corner of said member 58. as shown. A cable, 63, is attached to said spring hook, with its end secured to an anchor piece 64, and as said rock bar 51 and said members 52 and 58 move with it, the

hook is held by the cable 63, and consequently said member 58 is released and is drawn sidewise by means of a spring 65. The rearwardly projecting arm 60, strikes the spring member 18, and moves it sufliciently to release the lever 17, which is drawn back to its forward position by means of a spring, 66. Gn the lever 17, is a finger, 67, adapted to engage and move the vertical member 58 toward the vertical member 52, until it catches behind the hook 61 as said members come to their normal vertical position, as shown in Fig. 8. This mechanism is intended to retard the return movement of the back portions of the coin receptacles long enough for all the coins to pass out into the tray 41, that is, when the electro-magnet 16, has been ener ized and draws the lever 17 rearwardly until it catches behind the spring member 18, said lever 17 strikes and operates the ejector lever 21, as before de scribed, operating the ejector 20, to discharge the package. In this movement the member 58 is raised, the vertical member 52 is released from the notch 56, and the rock bar 51, is moved rearwardly, moving the backs of the coin receptacles through the link connections, as shown in Fig. 5, to allow the coins to drop out into the tray 41. The finish of this rearward movement trips the spring member 18, releases the armature lever 17, and the parts are r turned to their normal positions, as before described. Other retarding mechanism can be used in place of these levers and probably a dash pot of well known description and function would be just as effective and more simple, but this is only one feature in connection with the general mechanism shown for illustrative purposes.

Referring to Fig. 2, it will be seen that there is mounted near the hole 5 in the bottom of the package pocket, 5, a vertical rod, 69, in the bearings, 70, 70, with an angle finger, 71 atits upper end, and an outwardly and downwardly projecting bar, 72, near its lower end. The purpose of this member is to operate the closures 27 and 27, by striking the bar 29, when the package containing pocket 5 is empty. If this is the condition, the follower 9 will be at the bottom with its finger 9 projecting downwardly through the hole 5 and when said container is revolved, said finger 9 will engage the angle finger 71 at the upper end of said rod 69, and will turn it until its lower angle rod 72 strikes the bar 29, and operates said closures 27 and 27 and drops the coins which have been deposited in the coin receptacles back into the outer tray 40, for if the pocket is empty, no package can be de livered and the money is returned. This is the third way said closures can be operated to return the money to the purchaser. The three ways are by the rod 32, manually operated, by turning the container, through ratchet finger 35, and chain connection to the bar 29, and by the method above described, when the container pocket is empty. It will be understood, of course, that the purchaser turns the container 4 until the desired tier of articles is in the front, or discharge position. He then deposits the required coins to make up the pur chase price, and when the last coin is thus deposited in its proper coin receptacle, the proper circuits are completed, the electromagnet is energized and the ejecting mechanism is actuated. It will be understood, also, that the switch fingers 13, have previously been set to correspond with the various vertical pockets which contain articles for sale and that when said container is turned to bring any particular container pocket in the discharge position, there is also automatically closed the corresponding circuits by the fingers 13 and contacts 15.

I will next describe the electric circuit connections by means of which my invention accumulatively receives a number of diii'erent coins in different coin receiving receptacles and automatically discharges the purchased article.

Referring to Fig. 8 in particular, the twenty-five cent slot 23, is arranged for one coin and has two contacts in the bottom thereof, designated 74 and 75, and adapted to be connected by the coin placed therein. The ten cent slot, 241, is provided with two pairs of contacts, designated, 76, 77 and 78, 79, and is adapted to receive two dimes, each connecting a pair 01 contacts in two ditlerent circuits. The five cent slot is arranged to receive one coin and has two contacts, 80 and 81 to be connected thereby. The one cent slot is provided with four pair of contacts, 82, 83, and 84:, 85, and 86, 87, and 88, 89, and will receive tour one cent pieces, each connecting different circuit.

Circuit wires run from each of these con tacts to the spring contacts 15, 15. These circuits are designated with the corresponding reference numerals with a prime aiiix, that is, the circuits "from the contacts 7 1 and 75, are designated 74: and 75, and those from contacts 7 6 and 77 are designated 7 6 and 77. The main circuit wires from the electro-magnet 16, are designated 90 and 91, and come from any suitable source of supply, not indicated. The line 91 extends from the magnet to the lower spring contact element 15, as shown, and one of the supply lines, 92, runs direct to the first, or top spring element, 15, with a branch, 93, run ning to a switch, 94;, whereby a direct circuit to the electromagnet can be established by closing said switch. and without going through any of the circuits controlled by coins and the contact lingers, 13, on the container member 8. This switch enables the proprietor to manipulate the machine by simply closing the switch at will and it would, therefore, be a secret switch, or in a secret location. 1

As before described, the machine is set for automatic operation with the coins by moving the contact fingers 13, Fig. 6, inwardly, or in inactive positions, leaving those fingers out which are to close or connect the spring contact elements 15, 15. The machine as shown in Fig. 8, is set to require one twenty-five cent piece, one nickel, one dime, and two one cent pieces, making fortytwo cents in all necessary to actuate the machine.

Tracing the circuit through the setting used to illustrate the operation, the current passes through wire 92, to the spring element 15". These elements are not connected and the current passes out over line 75 to the contacts 7 5 and 7 1 through the twenty-five cent piece and back on line 7 1 to the next spring contact 15, thence to spring contact 15. Inasmuch as there is no ten cent piece connecting the upper contacts 7 6, 77, the circuit 7 6, 7 7 is open at the coin case, but the finger 13, connects spring contacts 15 and 15", so the current passes to 15, 15, wire 79, contact 79, ten cent piece, contact 78, wire 78 and to spring element 15*, to spring contact 15 line 81, contact 80, five-cent piece, contact 80, line 80, to contactspring 15E thence to spring 15 and through the finger 13 to spring contact 15 the circuit lines 82'83 being open because there is no one cent piece connecting contacts 82' and 83. From spring member 15 the current passes to spring contact 15 thence through finger 13 to spring contact 15, lines 8 1 85 being open because there is no one cent piece connecting contacts 84:85, thence to spring 15, line 87 contact 87, one cent piece and contact 86, and back on line 86' to contact spring 15, to contact spring 15 out on line 89 to contact 89, one cent piece and contact 88, back on line 88 to spring contact 15, and thence over line 91 to the electromagnet 16, causing the same to be energized and the lever 17 to be moved, which moves the ejector lever 21 and the ejector 20, discharging the purchased package. This movement of the ejector lever 21, also raises the lever 53, as before described, releases the vertical lever 52, and permits the rock bar 51 to be moved rearwardly, and in this movement the backs of the coin receptacles are moved and the coins deposited in the inner tray 11, all as hereinbefore described.

Thus it will be seen that the setting fingers 13 can be so adjusted that the proper spring contacts will be connected and when the other circuits are closed with the required coins and all of the required coins are deposited, the circuit to the electro-magnet is closed and the machine is actuated. If any one of the required coins should not be deposited, the circuit would be left open at that point and the machine would not operate. The coin contacts in the circuit must be closed by a coin, or the machine must be so set that the fingers 13, in the corresponding circuit, must be out to complete the circuit. When the coin contacts are to be connected by the proper coin, then the corresponding spring contact elements, or terminals, iii, are left open.

1 am aware that many changes in the details of construction and arrangement can beniade and simplification thereof'can be made, and l do not, therefore, limit my invention to the embodiment thereof adopted for illustrative purposes only, except as 1 may be limited by the hereto appended claims.
