  • the mechanism of the coin selector accomplishes its purpose in the following manner.
  • the trash eliminator When a coin is inserted in slot 14 it enters a vertical con chute 15 extending toward the rear of the machine and inclined slightly downward so the coin rolls into a trash eliminator 16.
  • the trash eliminator has a rear wall 17 that arrests the horizontal movement of the coin, and a slot 18 in the bottom thereof through which the coin drops against an inclined vane 19 carried by a horizontal pivot 20.
  • the vertical wall 17 In addition to its purpose of diverting coins against the vane of the trash el minator, the vertical wall 17 also absorbs all artificial momentum imparted to coins when they are inserted in the coin slot 14. This obviates all possibility of a person giving a slug an added mo mentum or particular motion that might cause it to pass through the coin selector where it would otherwise be eliminated.
  • the vane 19 of the trash eliminator 16 is carried by the pivot 20 so it hangs in an inclined position between the outlet 18 in the bottom of the trash eliminator 16 and the entrance 21 in the top of the coin chute 22.
  • the vane 19 has sufficent weight and inertia so that all trash coming out of the outlet 18 and striking its inclined surface will be deflected into a trask chute 23 and conveyed to a coin cup 24 on the front of the door 11 within reach of a person operating the machine.
  • the vane 19 is light enough, however, so that a coin, or a slug of approximately the same weight, will deflect it and drop down into the entrance 21 of the coin chute 22. Some light metallic articles, especially those so thin that they are liable to lodge in a coin chute and form an obstruction, will also be thrown out by the trash eliminator.
  • the coin chute 22 is inclined downward so coins roll through it and it is also provided with a curved portion 25 that changes the position of the coins so they enter the curve with an edge toward the front of the machine and emerge with a side toward the front of the machine.
  • the purpose of the magnet 27 is to eliminate slugs of paramagnetic material such as iron and its alloys. Such slugs will be attracted by the magnet 2'1 so they roll over the face 26 and down the side 28 into chute 29 leading to the coin cup 24. Coins, on the other hand, will not be attracted by the magnet 27 so they will roll over it and jump the entrance to chute 29 and also barrier 30 into a vertically disposed chute 31.
  • the barrier 30 is positioned so coins positively pass over it but so slugs, even though they are attracted but a small amount by magnet 27, will strike it and fall back into chute 29.
  • the pole pieces 32 of magnet 33 are positioned close together so there is just room for coins to pass between them, and they are also set at an angle to the direction of coin travel. Furthermore, they are elongated so they extend the full width of the coin chute so coins in passing through these pole pieces must pass at an angle through an elongated or linear magnetic field.
  • This magnetic field offers a resistance to coins and slugs passing therethrough dependent upon the amount and intensity of eddy currents or Faucault currents induced therein. Coins and slugs are affected different amounts in passing through this field, and the retarding action of the field deflects the coins and slugs from their line of travel according to their composition.
  • a separator 34 is placed in the coin chute below the pole pieces 32, and slightly to one side, so coins, and sings affected by the pole pieces as much or'more than coins, are deflected into chute-35; while slugs affected by the magnetic field less than coins pass into chute 36 which leads to the return cup 24.
  • Pole pieces 38 are preferably round and smaller in diameter than the coins, and they are located so one forms part of each side wall of chute 3'1 so there is just. sufilcient space between the opposing faces of the pole pieces for a coin to pass without danger of binding. While there appears to be no critical size, I have secured better results by using pole pieces somewhat smaller than the diameter of the coins so the magnetic field of the magnet is concentrated in an area substantially the diameter of the coins.
  • coins and slugs will be retarded different amounts according to their composition, shape, size, etc. Those retarded less, such as coins, will pass over a separating point 39 located beyond the pole pieces 38 substantially in line with the bottom of chute 37, while those retarded more, such as slugs, will not pass over the separating point 39 but will roll downward into rejection chute 40 that leadsto the return cup 24.
  • the present machine In order to prevent mutilated slugs from being accepted the present machine is arranged so slugs having a mutilated periphery, or any other expedient tending to reduce their rolling speed, will be rejected.
  • any slugs accepted by this portion of the machine must be of substantially the same dimensions and metallic composition as coins.
  • This group of slugs includes Canadian twenty-five cent pieces, French francs, and German marks. As Canadian twenty-five cent pieces are of substantially the same value as the coins for which the machine is adapted, it is arranged to accept them, but francs and marks are rejected by a coin selecting device incorporated with the releasing mechanism.

7 Claims.
This invention pertains in general to vending machines and in particular to a machine of this type comprising a coin selector, a change maker, and a merchandise magazine.
The coin selector is an improvement over the one described in my earlier patent application filed August 17, 1929, Serial Number 386,582. The merchandise magazine is of conventional construction and, therefore, forms no part of the present invention. Insofar as I know the change maker is new.
During the operation of vending machines equipped with my earlier coin selector the coin chutes were frequently found obstructed by pieces of paper, pins, and other miscellaneous articles inserted therein. Therefore, one object of this invention is to provide a vending machine with means for eliminating all such articles from the coin chute so they will not interfere with the operation of the machine.
Also, in my original coin selector one of the selecting operations was performed by sliding the coins down a chute through a magnetic field. I have found that this sliding action reduces the speed of the coins to such an extent in some instances that the accuracy of the separation is impaired. Therefore, another object of this invention is to provide a coin selector with means for passing coins through this selectingoperation without reducing their speed to a harmful degree.
Another selecting operation was performed by rolling the coins through a magnetic field and then accepting those that emerged at less than a certain speed. I have also found that in some instances such a machine will acceptspurious coins or slugs having the periphery thereof notched or otherwise deformed in such a manner that their rolling speed is reduced. Therefore, another object of this invention is to provide a coin selector with means for rejecting coins having a deformed periphery.
When using a vending machine some persons insert more than one coin in the machine before operating it, and I have found that the subsequent coins frequently interfere with its operation. Therefore, another object of this invention is to provide a vending machine with means for returning all coins that are inserted in it from the time it has accepted one coin until after it has been operated.
In the operation of vending machines it is frequently desirable to handle merchandise selling at an amount different from that of any standard U. S. coin. Therefore, another object of this invention is to provide a vending'machine with means for delivering one or more coins as change with each article of merchandise.
Other aims, objects, and novel features, will be apparent from the following description in 930. Serial No. 471,445
connection with the accompanying drawings, in
which: a
Fig. 1 is a reduced sectional side view of my improved vending machine showing the position of the merchandise magazine;
Fig. 2 is a fragmentary sectional side view of the door and magazine showing part of the operating mechanism;
Fig. 3 is a view of the inside of the door with the coin chute cover and portions of the change maker and coin selector broken away to show the path of the coin and the selector mechanism;
Fig. 4 is a fragmentary view of the door showing the change and the trash chutes; I
Fig. 5 is a fragmentary detail view of the inside of the door showing the releasing, transacting, and change making, mechanism;
Fig. 6 is a fragmentary vertical section of the door showing the lever that causes all coins to be returned while one is in the releasing mechanism;
Fig. 7 is a fragmentary vertical section of the door showing part of the change maker and change chute;
Fig. 8 is a fragmentary horizontal section along the line 8-8 of Fig. 5, and;
Fig. 9 is a fragmentary horizontal section along line 9-9 of Fig. 5.
The present machine is especially adapted to accept twenty-five cent pieces and deliver a package of merchandise such as cigarettes and two five-cent pieces in change. It may be adapted, however, to accept coins of a different size and value; to deliver merchandise without delivering change; or to deliver change without delivering merchandise. The machine as shown is adapted to deliver from one to four coins as change but this number may be increased when the machine is adapted to receive coins of greater value, or when it is used for other purposes, such as delivering change only.
The price range of articles the presentmachine is adapted to handle is unusually large. For instance, when the machine is adapted to receive twenty-five cent pieces it may be caused todeliver articles of merchandise selling for 592, 10, 15, 20, or 25, by adjusting it to deliver the proper number of five-cent pieces in change. It may also be arranged to deliver articles selling from 21 to 24 by adjusting it to deliver the proper number of one-cent pieces in change. As the adjustments necessary to change the number of coins delivered may be easily made by the owner of the machine, he may arrange it to deliver twenty-five cent articles for twenty-five cent pieces and then when desirable run out price sales by arranging the machine to deliver one or more one-cent pieces as change with each article of merchandise delivered. The scope of the machine may be greatly enlarged by ma it to receive and deliver coins 'of other sizes, and by increasng the number of coin magazines so it will simultaneously deliver coins of two or more denominations as change.
I In order to simplify the description of the machine embodying the present invention and, at the same time, make it more definite, the following terms will be used comprehensively as defined:
The term coin" or coins will be used to designate one or more coins which the machine is adapted to receive: In the present case this is U. S. twenty-five cent pieces; it being understood that the present invention covers machines adapted to receive any coin, or any metal check or token having a special monetary value or magnetic quality, and that this defined limitation applies only to the specific embodiment of the present invention described herein.
The term slug" or slugs will be used to designate one or more genuine coins for which the machine is not adapted; deformed coins of any size or value; foreign coins; metal checks; metal tokens; metalwashers; disks of metal; spurious coins; counterfeit cons; and all other metal articles in the shape of or resembling coins.
The term trash" will be used to designate miscellaneous articles not resembling coins;-such as pins, disks of paper,.cardboard, celluloid, bakelite, and such like, that are inserted in vending machines.
The preferred form of the invention as shown in the drawings comprises a vending machine having a suitable casing 10 and a door 11 closing the front thereof. Supported within the casing 10 is a merchandise magazine 12 of a form well known in the art, and attached to the inside of the door 11 are a coin selector, a transacting mechanism, and a compartment 13 in which one or more articles of merchand se-may be displayed.
The door 11 is provided with a slot 14: in which coins are inserted for the purpose of releasing the vending machine so it can be manually operated to vend or dispense an article of merchandise such as that displayed in compartment 13. Before a coin inserted in slot 14 can reach the releasing mechanism, however, it must pass through the coin selecting mechanism, and the purpose of this mechanism is to allow only genuine coins to reach the releas ng mechanism, and to reject and return all slugs and trash. The mechanism of the coin selector accomplishes its purpose in the following manner.
When a coin is inserted in slot 14 it enters a vertical con chute 15 extending toward the rear of the machine and inclined slightly downward so the coin rolls into a trash eliminator 16. The trash eliminator has a rear wall 17 that arrests the horizontal movement of the coin, and a slot 18 in the bottom thereof through which the coin drops against an inclined vane 19 carried by a horizontal pivot 20.
In addition to its purpose of diverting coins against the vane of the trash el minator, the vertical wall 17 also absorbs all artificial momentum imparted to coins when they are inserted in the coin slot 14. This obviates all possibility of a person giving a slug an added mo mentum or particular motion that might cause it to pass through the coin selector where it would otherwise be eliminated.
The vane 19 of the trash eliminator 16 is carried by the pivot 20 so it hangs in an inclined position between the outlet 18 in the bottom of the trash eliminator 16 and the entrance 21 in the top of the coin chute 22. The vane 19 has sufficent weight and inertia so that all trash coming out of the outlet 18 and striking its inclined surface will be deflected into a trask chute 23 and conveyed to a coin cup 24 on the front of the door 11 within reach of a person operating the machine. The vane 19 is light enough, however, so that a coin, or a slug of approximately the same weight, will deflect it and drop down into the entrance 21 of the coin chute 22. Some light metallic articles, especially those so thin that they are liable to lodge in a coin chute and form an obstruction, will also be thrown out by the trash eliminator.
The coin chute 22 is inclined downward so coins roll through it and it is also provided with a curved portion 25 that changes the position of the coins so they enter the curve with an edge toward the front of the machine and emerge with a side toward the front of the machine.
Coins leaving the curve 25 of the coin chute 22 next pass over the face 26 of a horseshoe magnet 27 forming part of the floor 28 over which the coins roll. The purpose of the magnet 27 is to eliminate slugs of paramagnetic material such as iron and its alloys. Such slugs will be attracted by the magnet 2'1 so they roll over the face 26 and down the side 28 into chute 29 leading to the coin cup 24. Coins, on the other hand, will not be attracted by the magnet 27 so they will roll over it and jump the entrance to chute 29 and also barrier 30 into a vertically disposed chute 31. The barrier 30 is positioned so coins positively pass over it but so slugs, even though they are attracted but a small amount by magnet 27, will strike it and fall back into chute 29.
Coins that jump the barrier 30 into chute 31 drop vertically downward between the inclined pole pieces 32 of magnet 33.
The pole pieces 32 of magnet 33 are positioned close together so there is just room for coins to pass between them, and they are also set at an angle to the direction of coin travel. Furthermore, they are elongated so they extend the full width of the coin chute so coins in passing through these pole pieces must pass at an angle through an elongated or linear magnetic field. This magnetic field offers a resistance to coins and slugs passing therethrough dependent upon the amount and intensity of eddy currents or Faucault currents induced therein. Coins and slugs are affected different amounts in passing through this field, and the retarding action of the field deflects the coins and slugs from their line of travel according to their composition. A separator 34 is placed in the coin chute below the pole pieces 32, and slightly to one side, so coins, and sings affected by the pole pieces as much or'more than coins, are deflected into chute-35; while slugs affected by the magnetic field less than coins pass into chute 36 which leads to the return cup 24.
Such slugs as are deflected more than coins are separated and rejected by conducting all coins and slugs entering chute 35 into chute 37 that is inclined so the coins and slugs roll down it through the pole pieces 38 of magnet 39. Pole pieces 38 are preferably round and smaller in diameter than the coins, and they are located so one forms part of each side wall of chute 3'1 so there is just. sufilcient space between the opposing faces of the pole pieces for a coin to pass without danger of binding. While there appears to be no critical size, I have secured better results by using pole pieces somewhat smaller than the diameter of the coins so the magnetic field of the magnet is concentrated in an area substantially the diameter of the coins.
In rolling between the pole pieces 38 in the magnetic field of magnet 39 coins and slugs will be retarded different amounts according to their composition, shape, size, etc. Those retarded less, such as coins, will pass over a separating point 39 located beyond the pole pieces 38 substantially in line with the bottom of chute 37, while those retarded more, such as slugs, will not pass over the separating point 39 but will roll downward into rejection chute 40 that leadsto the return cup 24.
In order to prevent mutilated slugs from being accepted the present machine is arranged so slugs having a mutilated periphery, or any other expedient tending to reduce their rolling speed, will be rejected.
Down to this point the coin selector is provided with an eliminator for taking out trash; a magnet for taking out paramagnetic slugs; a magnet for taking out slugsdeflected less than coins; and a magnet for taking out slugs retarded more than coins. Therefore, any slugs accepted by this portion of the machine must be of substantially the same dimensions and metallic composition as coins. This group of slugs includes Canadian twenty-five cent pieces, French francs, and German marks. As Canadian twenty-five cent pieces are of substantially the same value as the coins for which the machine is adapted, it is arranged to accept them, but francs and marks are rejected by a coin selecting device incorporated with the releasing mechanism.
Francs and marks are similar to coins but they are slightly smaller in diameter, and this difference in size is great enough so they may be positively separated by it. This separation is eflected by a pair of pins 43 carried by a release lever 42. Coins coming down chute 41 are conducted to these pins, which are spaced apart so coins will be held by them but so francs and marks will pass between them and then down rejection chute 44 to the return cup 24. Coins held by these pins effect the release of the machine in a manner to be described later.
Sometimes there are inserted two or more coins in the coin slot before operating the machine to eifect a delivery. It has been the practice heretofore to provide vending machines with some means for storing such coins until the machine was operated, but such devices are unsatisfactory because, even under the best of conditions, two coins will frequently become wedged in the coin chute 'side by side and form an obstruction. Therefore, I obviate all possibility of the present machine becoming clogged in such a manner by providing it with means for returning subsequent coins instead of storing them.
This means comprises an interference lever 45 having a hub 46 carried between a stationary pivot 47 and an adjustable pivot 48 (Figs. 5 and 6). The lower end of this lever has an inclined face 49 in the coin path so a coin entering the release mechanism will strike it and move the lever to interference position and hold it there as long as a coin is resting on pins 43 or release lever 42. When in interference position the upper end 50 of lever 45 forms an obstruction in the lower end of coin chute 37 so coins that would ordinarily enter chute 41 and be conducted to the releasing mechanism are deflected into chute 40 and conducted to the coin return cup 24. A spring 51 carried by the vending machine frame presses against the upper end of lever 45 and moves it back to normal position when the machine is operated and the releasing coin is ejected from the releasing mechanism.
The operating or transacting mechanism that is released by an accepted coin and manually actuated to effect the delivery of an article of merchandise comprises a shaft 51 journaled in a bearing boss 52 that forms part of the door 11. Rigidly attached to shaft 51 in front of door 11 is a manually operable handle 53, and rigidly attached to the same shaft at the rear of door 11 are a disk 54 having one or more pins or sprews 55 projecting from the back face thereof for operating the change maker; and a gear 56 having a function that will be'fdescribed later.
The merchandise magazine 12 is driven by-s'haft 51, and in order to maintain the transacting mechanism and the .merchandise magazine in their proper relative position and, at the same time, permit the door 11 to be opened, a'sep arable joint is provided comprising a driving member 57 rigidlyatt ached to shaft 51 and having two pins projecting from the back face thereof at opposite sides of shaft 51, and a driven member 59 carried by shaft 60 of the merchandising magazine and having two receptacles 61 on the front face thereof, in which pins 58 are respectively positioned when door 11 is in closedposition but from which they are withdrawn when the door is opened.
The merchandise magazine comprises a plurality of merchandise receptacles 62 carried by an endless chain 63 that runs over suitable sprocket wheels 64 and 65 respectively supported by shafts 66 and 67 that are in turn carried by the vending machine casing 10. The merchandise magazine is driven by a chain 68 running over a sprocket wheel 69 carried by shaft 66, and sprocket wheel 70 carried by cross shaft 71 that is driven by shaft 60 through a pair of bevel gears 72.
The transacting mechanism also comprises a shaft 73 carried by door 11 and having the following parts rigidly joined and rotatable thereon: a movement stop 74 having two faces 75 that alternately come in contact with a detent '76 depending from release lever 42; a ratchet wheel 77 that coacts with pawl 78 carried by stud '79 and held in contact with wheel 77 by spring 80 so the transacting mechanism can not be moved in reverse direction; and a gear 81 twice the size of gear 56, with which it is enmeshed, so it makes but half a revolution while handle 53, and the mechanism movable therewith, makes a complete revolution.
Release lever 42 is carried by stud 81' so it is free to rotate within the limits of its travel. Its weight, and that of other parts attached thereto, is distributed so that normally detent 76 lies in the path of one of the stop faces 75 thereby preventing the transacting mechanism from being actuated, but so a coin that has come to rest between pins 43 will raise detent 76 above the path of either of the faces '75 thereby releasing the transacting mechanism so it may be manually actuated through its cycle of movement to effect the delivery of an article of merchandise. During this cycle the coin must be ejected from between pins 43, and the release arm 42 must be positively restored to stop position to eliminate all possibility of the transacting mechanism being actuated through a second cycle until it has again been released by another coin.
A coin that has released the transacting mechanism is ejected from between pins 43, and release lever 42 is restored to stop position, by restoring arm 82 rigidly attached to release arm 42 and moved by a laterally projecting pin 83 lying in cam slot 84 cutin the front face of stop disk 74; and an ejector arm 85 carried by stud 86 and having an ejector pin 87 projecting laterally from the lower end thereof, and an operating face 88 near supporting stud 86 that coacts with pin 89 carried by release lever 42. Ejector arm 85 is held in normal position by a retractile spring 90.
A transacting movement of the vending machine rotates stop disk 74 only half a revolution, consequently, cam slot 84 in the face thereof is double so its cycle of movement is twice repeated during a revolution. Each half of the cam slot 84 has an ejector face 91, that moves release lever 42 in release direction beyond release position to eject the releasing coin from pins 43, and a restoring face 92 that positively moves release lever 42 from ejecting position back through release position to stop position.
For the purpose of checking the operation of the vending machine by keeping a record of the number of times it has been actuated, a counter 93 of well known form is attached to the inside of the door 11 by suitable means such as screws 94 so it is operated by pins 95 carried by gear 81 through a push rod 96 carried by bracket 97 attached to door 11 by screws 98. The operating pins 95 are located at opposite sides of gear 81 so each time the vending machine is operated one of the pins 95 will depress the rod 96 and advance the counter. When push rod 96 is not in contact with one of the pins 95 it is restored to normal position by a spring incorporated in the counter 93.
The change maker comprises a bracket or support 99, attached to the inside of the door 11 by screws 100, having a vertical receptacle 101 supporting a removable coin magazine 102, and a horizontal guideway 103 carrying a reciprocable slide 104 for pushing coins out of magazine 102 one at a time. This slide 104 has a depending projection 105 carrying a horizontal pin 106 positioned in slot 107 in the upper end of arm 108 loosely carried on stud 109. Arm 110, also loosely carried by stud 109, has a lower end 111 lying in the path of pins 55, and an upper end 112 carrying laterally projecting pins 113 ad 114. Retractile spring 115 is carried under tension in a partially extended condition between pin 113, carried by arm 110, and pin 116 carried by a stationary part of the mechanism. Pin 114 rests against face 117 of arm 108 and also carries one end of spring 118 having the other end thereof carried by pin 119 in turn carried by arm 108. Spring 118 is carried under tension in a partially extended condition so pin 114 is normally held in contact with face 117 of arm 108. Coin chute 120 is carried by the mechanism of the vending machine in such a position that coins ejected from the coin magazine 102 will be conveyed to the coin return cup 24.
In operating the vending machine a coin is inserted in coin slot 14 where it rolls back and enters the trash eliminator. In passing through the trash eliminator it drops downward striking the inclined vane 19, which it deflects, and then passes on down into the coin chute 22. This chute changes its direction of movement so it travels parallel to the face of door 11 in a downwardly inclined direction over magnet 27 and the entrance to chute 29 to chute 31 where it drops downward through pole pieces 32 and the magnetic field of magnet 33 which deflects it into coin chute 35. In this chute it is rolled in a downwardly inclined direction through pole pieces 38 of magnet 39, over the entrance to chute 40, and into chute 41 which conveys it to the release lever 42 where it comes to rest between pins 43.
Other articles inserted in coin slot 14 are taken from the chute through which coins travel and returned to coin cup 24 where they may be reclaimed. Trash is eliminated by the angular vane 19 of the trash eliminator 16 and deflected into chute 23.
Paramagnetic slugs are attracted by magnet 27 and caused to enter chute 29. Non-magnetic slugs deflected by the magnetic field of magnet 33 less than coins enter coin chute 36. Nonmagnetic slugs whose movement is retarded by the magnetic field of magnet 39 more than coins enter chute 40. Slugs smaller in diameter than coins but of similar metallic composition pass between pins 43 and enter chute 44. Chutes 23, 29, 36, 40, and 44, all lead to coin return cup 24.
When a coin comes to rest between pins 43 its weight moves the release lever 42 into release position in which detent 76 is raised out of the path of stop faces 75 of movement stop 74 so the transacting mechanism can be manually operated. This transacting operation is effected by the vendee who grasps the handle 53 and rotates it one complete revolution. This operation advances the merchandise magazine so the next merchandise receptacle 62 is brought opposite merchandise delivery opening 121 where the merchandise in receptacle 62 may be grasped and removed by the vendee.
This transacting movement also operates the change maker. As the transacting movement is operated each of the pins 55 makes a complete revolution and strikes the lower end 111 of lever 110 thereby moving it, together with arm 108 and slide 104, so the slide ejects a coin from coin magazine 102 into coin chute 120. After each of the pins 55 have passed the lever 110 the parts are restored to normal position by spring 115.
The purpose of spring 118 is to allow the transacting mechanism to be operated in case the change maker should become obstructed by a deformed or misplaced coin. In such a case arm 110 will be moved as usual but instead of moving arm 108 and slide 104 it will elongate spring 118 which is strong enough to normally drive the slide but will stretch when the slide is obstructed.
During the operation of the transacting mechanism the parts mounted on shaft 73 make but half a revolution. Therefore, one of the pins 95 depresses rod 96 and advances the counter 93 one position. Also, during this operating movement, cam face 91 of 0am slot 84 strikes pin 83 carried by arm 82 and depresses the end of release lever 42 carrying pins 43 considerably below release position. At the same time, pin 89 carried by the release arm 42 strikes face 88 of lever 85 and raises its lower end so pin 87 carried thereby strikes the under side of the coin resting between pins 43 and ejects the coin from between the pins so it falls down coin chute 122 which conveys it to coin receptacle 123 within the vending machine. After the coin has been ejected from pins 43 of the release lever, cam face 92 of the cam slot 84 moves the release lever'42 back to stop position where the detent 76strikes stop face 75 as the movement is continued and prevents further movement of the transacting mechanism until it is again released by-another coin. As the release lever is moved to stop position by the cam, coin ejecting arm 85 is restored to normal position by spring 90. When in stop position there is sufficient room in the cam slot so the release lever can move to release position before pin 83 of ejector arm 82 strikes the wallof the cam slot. Therefore, when the cam slot 84 is in stop position the release arm 42 is free to move between stop and release position. Then, during a transaction movement, the cam slot moves the release lever first, to ejection position, and then back to stop position where it is released so it is again free to move to release position under the influence of a releasing com.
When the last merchandise receptacle 62 containing merchandise is moved opposite the delivery opening 121, a pin 124 carried by one of the merchandise receptacles moves an arm 125 on a pivot 126, suitably carried by a stationary portion of the mechanism, so the word, empty, or other suitable inscription, appearing on target 12''! is visible through opening 128 from the front of the vending machine. During its movement to empty position, an inclined face 129 moves pin 130 across coin slot 14 thereby preventing a coin from being inserted in the vending machine while it is empty. A suitable spring, not shown, restores pin 130 to normal position when the merchandise magazine is filled with merchandise and moved back to start position. The target and its supporting lever are moved back to normal by gravity.
