COIN-CONTROLLED .V ENDING MACHINE Application filed January 19, 1928. SeralvNo. $247,912.`

This invention relates to vending machines, and particularly to an improved coin controlled vending machine, wherein the )arts have been simplified while retaining a number of safety or projecting appliances which prevent the use of most spurious coins without interfering with the proper operation oi' the machine when a genuine coin is used.

The object ot the invention is to provide a simplified toi-m of coin controlled vending machine, wherein the parts are so constructed that there is little liability of getting out `of order, while at the same time functioning properly, notwithstanding alnise through the attempted use of washers or other spurious coins;

Another object of the invention is to profide a coin controlled vending machine which is easy to operate, and which will automatically lock itself against operation when the last article has been vended.

il still further object of the invention is to provide in a coin controlled vending machine, means for permitting the actuation of the machine once after a coin has been inserted, with the parts so arranged as to prevent a second operation.

ln the accompanying drawings-P- Figure 1 is a longitudinal vertical sectional view through a vending machine, disclosing aii embodiment or' the invention, the operating mechanism being shown in elevation.

Figure 2 is a longitudinal vertical sectional view through the lower part ot the vending machine shown iii Figure 1, said view being taken approximately on line 2-2 ot' Figure 6.

Figure l is a fragmentary sectional view through Figure 2, approximately on line 9i- 3.

Figure 4 is a view similar to Figure 2, but showing the parts moved slightly toward an operated position.

Figure 5 is a fragmentaryY sectional view through Figure 2, approximately on line Figure 6 is a horizontal sectional view through Figure 1, approximately on line y 6 6, the saine being on an enlarged scale.

Figure 'T is a fragmentary sectional View through Figure approximately on line i- Roter-ring to the accompanying drawings by numerals, 1 indicates a support of any kind, as for instance, a postor wall. A

screw i2, having a large head, is carried by` the wall 1 and is adapted to tit into the` slot 3 in the back wall 4. Thisback Wall telescopically tits into the casing 5 and the cas` ing is held thereto by reason of the for wardly extending portion 6 having a de-V pending flange 7 engaged by the bolt-8 of the lock 9. At the lower end, the wall 4 is provided with a forwardly extending sec,- tion 10 carrying one or more lugs 11 which are adapted to be thrust through desirable openings 12 in the bottom `13 of casing 5. lVhen` it is desired to move t-lie casing 5 to secure acress to the interior of the casing, lock 9 is unlocked by a suitable key and casing 5 grasped at the upper part and swung outwardly until free of member 6. The casing is then lowered until free of the lug or lugs 11. The `wall 4 is provided Wit-h a forwardly extending flange 14on each side which slidingly fits into the casing 5 and..

thereby prevents any one forcing an instrument into the casing at this point. In

addition, a` curved bracing member 15, is

soldered or otherwise secured to members l and 10 at the lower end. member acts as a chute for guiding articles vended `from the magazine 16 to the bottom 13 near the opening 17. The opening 17 is suliiciently large to permit part of a hand to be inserted so that the chewing gum or `other articles vended may be readily grasped and removed. y

The casing 5 is provided with a. trans verse bar 18 near the top, and this bar cal ries one or more retaining and guiding loops 19 through which the magazine or magazines 16 are looselv forced. As indicated u n in Figure 6, the casing 5 is sufficiently large forthree magazines 16 and -three duplicate actuating mechanism. but only one has been shown completely, but as the others are identical, the description of this one will apply to the others. It is, of course, evident that in a vending machine only one mechanism may be used, or a large number, as each separate mechanism and associated parts, are identical with the other mechanisms and associated parts. The magazine 16 is preferably rectangular because the goods are of that shape, and preferably closed except at the front as indicated in Figure 6. One or a large number of articles Q0 may be placed in tie magazine 16 and then a follower block 21 placed on top.

This bracing This follower block may be of any desired matefial, as for instance, cast iron or brass, whereby ample weight is provided for holding the articles in proper position to be ejected. Preferably the follower block 21 is provided with a pair of depending legs 22, there being one leg on each side whereby the weight is placed on the articles 2O near the respective ends. Pivotally mounted on top of the follower block 2l is a locking plate 23, which plate is rounded at 2st and provided with an aperture 25 adapted to receive a pin 2G as the last article 2O is ejected. lhis will prevent the pin 2G and associated parts, including the plunger 27, from moving back to the position shown in Figure 2.

As the plunger is locked in an inner or operated position, customers will know that the particular magazine associated with this plunger is empty. It tor any reason, a person should drop a coin into the coin slot 28, it will merely drop down in front of the wall 29 and land on the bottom 13 where it may be readily recovered by insorting the hand through opening 17. At the lower end, the magazine 16 is provided with a notch 30 on each side, said notches accommodating the upstanding portions 3l of the wall 32. In this way the magazine is removably placed in position so that whenever the casing 5 is removed, the magazine may he quickly removed so as to supply the same with additional articles 20.

lllhen a coin is dropped through une coin slot 28, it will pass downwardly through the opening 33 and also through the opening Sil into the space or chamber 35. Il the coin is of magnetic material, as for instance, an ordinary iron washer, the magnet 36 will attract the same and hold the coin opposite the magnet so that when the plunger 27 is pushed, the coin will drop down in iront of the wall 29 and strike the bottom 13 without causing an ejection oitx one of the articles 20. It the coin is not magnetic but has a hole in the center, it will pass the magnet 36 and strike the shoulder 37 et what may be termed a weighing mechanism 38. lf the coin is of the usual weight it will svving this weighing mechanism to one side and the coin will drop down until it strikes the wall 39 and pin 40. As indicated in dotted lines in Figure 3, when the plunger 27 is actuated, it will merely push the coin onto the actuating pin l1 as the coin has a. hole therein. If the coin was not magnetic, but not as heavy as a genuine coin, it would rest on the shoulder 3?', and when the plunger 27 is actuated, it would drop pas" the end ot the actuating pin Lil and, the "ore, fail to operate the mechanism. li the coin was, however ot the right kind, as tor instance, genuine one cent piece, it would pass the magnet 86, strike shoulder 37 and swing the weighing mech anism out of the way and move down until it restedon the pin ll0 and against the wall 39. llillien the genuine coin is in this position and plunger 2T is forced inwardly, the actuating wall Lil-2 will push the coin against the end of the actuating pin ill and innove the pin and associated mechanism IGrwaidly as Indicated in Figure el. ritter the first slight movement, the enlarged end or section Lll ol pin ell will move the raclr i3 sutliciently to receive the end ot pawl lll into the lirst notch. lt the pressure on the plunger 2T was released, the parts would not move bach, hough the plunger 27 would move back. However, by the time that the end of pawl engaged the lrst notch in rack d3, the coin would be occupying` a space over but at the left of wall 29, whereby when the wall d2 and associated parts move bach the coin will be dropped into the coin container or receptacle do. This, oit' course, will not eject any oit the articles 20, but by again pushing the plunger 2'5", the parts will be further actuated, and it the plunger is pushed in tar as possible, the ejector lo will Yforce th lowermost article 2O onto the chute l5 as indicated somewhat in Fig ure 4l and this article will slide down 'to a pointnear opening 1T. Alfter this actuation, the plunger 2T is released, and 'the parts aain moved bach to the position shown in Figure 2 ready for a second actuation. lt the plunger 27 was actuated a second time without a coin, it would merely move inwardly without causing an artuation of any ot the parts. rlhis is caused by the tact that the wall Llf2 is really a lil-shaped structure and rigidly secured to the respective walls 39, so that when moved lioiwvaidiy without a coin resting on the pin d0, no movement will bc given to Vthe pin all. The pin Ll1 is guided by raison ot' the tact that it extends through a suitable aperture in an upstanding wall a? carried by the base plate d8, which base plate merges into the wall 32. A web or upstanding flange i9 is formed integral with or rigidly secured to the auxiliary pin or section Ll1, and to this web is rigidly secured or formed integral therewith, the ejector d6. This ejector consists preferably oi" a flat plate 50 having an upstanding flange 51 on each side. The pin 26 is rigidly secured to the plate 5G and extends upwardly through the ld-shajicd magnet 36 so that when spring 52 acts to force the plunger 27 and walls 39 bacl: to

their itormer position as shown in figure 2, themagnet which is secured to these walls will pull pin 2, ejector dit and associated parts bach to their starting point. The walls Sti and and as iciated parts, may be called an actuatini nue as the saine are moved by the plu L.; and c; isc both a 'forward and rearwa d movcnunt ot the Cil llO

other parts. Unel of' the Walls 39 -is provided with a lateral extension 53 through Which plunger 27 extends and to which t e plunger is secured by any suitable means, as for instance, a set screw` The plunger also slidingly tits into a suitable aperture in the Wall 32 and through the front stationary wall 54 as Well as through the front of the casing 5. Walls 32 and 54 are connected by a side plate 55, and in fact, the side plate 55, wall 54, wall 32 and base plate 4S, may be of one solid casting or may be made separate and rigidly secured together. The base plate 48 and Wall 32 are slotted for accommodating the rack 43, auxiliary pin 41' and Web 49.

In respect to the action of the rack 47, it will be noted that the auxiliary pin 41 is provided With a singlenotch 56 which is engaged by the bar 57, which bar has a pair oi supporting arms 58 pivotally mounted at 59 on the Walls 39 of the actuating frame. Ordinarily, the bar 57 is held out of notch 56 by a cam 57', but after notch 56 has been moved through the `insertion of a coin of the proper size, thebar 57 will drop down into this notch as shown in Figure 4 so as to force the auxiliary pin 41 and associated parts, including ejector 46, to a fully operated position before these parts will move back to their starting point.

In case a Washer having an aperture therein, has been pushed onto pin 41, said Washer will remain on pin 41 until the pin 41 has been actuated by a correct coin. As soon as the pin 41 has been pushed inwardly by a correct coin as far as it will go, the

coin will press the Washer against ring 59 so as to slightly compress the spring 60. As soon as plunger 27 is released, the spring 60 will function to force the Washer off of the pin 4l, whereby it Will drop into the coin box along with the genuine coin.

In regard to the Weighing mechanism 38, it Will be noted that the same is made up ot' plates 61 and 62 connected with' a loop portion 63 which accommodates the pintle 64 carried by suitable ears depending from the plate 65, which plate is bolted or otherwise rigidly secured to the extension 66 of the stationary Wall 54. A pin 38 is carried by Wall 39 and when the parts are in the position shown in Figure 2, a pin is spaced a short distance from'plate 61 so that a genuine coin may strike shoulder 38 and then move past the lower part of the plate 61 so as to rest on pin 40. Vhen piece of paper or light coin is stopped by the shoulder 37, it remains at this place until the plunger 27 is pushed. As the plunger moves, pin 3S will strike plate 62 and swing the parts to the position shown in Figure 4, whereby paper or spurious coins held by the shoulder 37, may fall down on to the floor i3. As shown in Figure 4, there is an ample space or chamber' whereby any ofthese foreign articles may readily drop out of the way so that a clean path will be provided torthe next true coin.

When the machine is in the position shown in Figure 2 and a proper coinY is linl serted, it will drop down and strike the shoulder 37 and move the Weighing device to one side and then Will drop down until` it strikes the pin 40 in front of the end of pin 41. The plunger 27 is then pushedin` wardly as far as possible. As the plunger moves inwardly, the coin is slid along the pin 40 and will strike against the `pini41.l From Figure 2 it will be noted that the pin 40 extends beyond the Wall 29 so that whew ever the coin is released it will drop the coin inthe coin box it' the mechanism is beingproperly actuated. As the pin 41 moves, it Will carry the ejector 46, which ejector will strike the lowermost article 2O and torce the same out of the magazine onto the chute 15;` As soon as this has been done, thefplunger 27 will be released and returned bythey spring 52. As the plunger is returned, itiv will carry with it the actuating frame rincluding walls 29, and then in turn will move the magnet 36 back and this magnet will strike the pin 26 and move `the pin 26 and associated parts back to their starting `point so that the parts areagain in position fora second actuation.
