Still further objects of the invention are to provide an improved coin controlled machine l. which is durable, attractive, versatile, eicient conveyor clutch members and centering wheel lock.

Referring more in detail to the drawings: The invention, in its general aspects, is best illustrated in Fig. 1, wherein it is shown embodied in a housing I of suitable conformation, material and finish, which housing is adapted to encase a plurality of endless conveyors preferably of the character indicated at 2, Fig. 2, the endless conveyors preferably being formed of a series of pockets 3, Fig. 1l. By so arranging a plurality of the conveyors in the housing, it is apparent that the capacity of the vending machine is increased to an extent, for example when two conveyors are employed as is preferable in the present instance, approximately four times the height of the housing.

It is contemplated that the pockets 3 be oi varying sizes to accommodate articles of merchandise, such as candy bars, of different length, width and thickness, to the end that a great variety of merchandise may be vended from the machine.

The machine is entirely selective and provision i A is made for selection of merchandise by providing a cover 4 for suitable engagement with the housing and adapted to be locked thereto by a suitable locking device 5 for cooperating with the housing in enclosing the merchandise filled conveyors. The cover 4 has elongated merchandise viewing panels 6 and 1 for the purpose of permitting a buyer to determine what types of merchandise the machine contains. A suitable grill 8 is mounted behind each panel for the purpose of preventing the panels from becoming soiled, should the candy bars, for example, become soft and tend to smear the panels when they are moved in back of the panels by the conveyors. The grills 8 also tend to prevent the wrappings of the merchandise from becoming damaged during travel, and also prevent theft of articles from the machine, should the panels be broken.

A conveyor actuating machanism 9 is provided as a part of the machine for turning the conveyors, and an auxiliary cover I0 is provided for covering the conveyor actuating mechanism, as well as completing enclosure of the inner operative parts of the machine, the auxiliary cover I0 preferably being hinged, as at I I, to the housing I and being suitably engageable, as indicated at I2, with the cover 4 whereby the casing for the machine, comprising the housing I, cover 4, and auxiliary cover I0, securely houses the machine and prevents unauthorized entrance thereto.

A dispensing outlet or delivery opening I3 is provided, preferably in the lower forward portion of the auxiliary cover I 0, and observation panels I4 and I5 are provided at the upper portion thereof for permitting a customer to determine what brand or type of commodity is in dispensing position in the machine. The dispensing position of articles to be sold is directly in back of each ofthe doors I6 and I1, which may be viewed through the panels I4 and I5.

This vending machine is coin controlled and a suitable coin slot I8 is therefore provided for feeding the machine to make it operate in response to actuation of an operating lever I9.

It is further intended that only one article is to be vended upon acceptance by the machine of a single genuine coin and, for this reason, provision is made for shifting the dispensing mechanism into operative position relative to one merchandise containing pocket in one conveyor, this positioning of the vending mechanism being carried out by manipulation of the: shifting lever 20.

Each article of merchandise is preferably contained in a single pocket 3, Fig. 11, and the pockets 3 are preferably stamped and shaped from a one-piece blank in such a manner as to provide a bottom wall 25, a top wall 26, and end walls 21. The front of the pocket is open to provide for filling the pocket and ejecting an article therefrom, and the rear of the pocket is provided with spaced openings 28 to provide for the passage of article ejecting members, later described. Preferably formed integrally with each of the pockets are spaced pairs of ears 29 and 30 having aligned apertures therethrough for receiving suitable fastening devices as indicated, for example, at 3| and 32 in Fig. 2, for interconnecting a plurality of the pockets to build up each of the endless conveyors 2.

In order to mount the endless conveyors 2 in the housing, the conveyors are each mounted on a framework 33, Fig. 2, adapted to be slid bodily into the housing for enclosure by the same, the framework 33 also supporting and forming a mechanisms embodying the present invention. 'Ihe framework 33 comprises suitable uprights interiorly braced relative to each other preferably by a diagonally disposed brace member 34, a laterally disposed brace member 35, diagonally disposed brace members 36, and a horizontally disposed crown member 31. The crown member 31 has mounted thereon a suitable bracket forming a bearing support for the inner end of spaced horizontally aligned shafts 38. A pair of spaced sprockets or the like 39 is rotatably mounted on the shafts 38, the sprockets being provided on their peripheries with conurations adapted to receive the adjacent portions of the ears of the conveyors formed by the merchandise containing pockets in such a manner as to prevent slippage of the conveyors when moved thereover.

The sprockets 39 on the upper shafts 38 provide an upper run for the endless conveyor, the lower run of each of which is defined by similarly arranged sprockets 4I), Fig. 2, spaced apart a distance equal to the distance between the pairs of ears on the container pockets forming the links for the conveyors.

While the sprockets 40'are themselves substantially similar, and while they are mounted in spaced horizontal alignment adjacent the lower end of the framework 33, Figs. 5 and 10, the arrangement for so mounting them is different from the arrangement for mounting the upper sprockets. The left hand pair of lower sprockets, when the vending machine is arranged as shown in Fig. 1, is mounted on a horizontal shaft 45, Figs. 5 and 10, one end 46 of which is rotatably mounted in upright 41 and the other end 48 of which is rotatably mounted in a vertically disposed supporting partition 49 welded or otherwise secured to the bottom 50 of the framework 33.

The lower right hand pair of conveyor receiving sprockets is mounted on a tube 5I which is rotatably mounted in suitable bearings in a vertically disposed supporting partition 52, substantially similar to the partition 49, and in a suitable bearing in the upright 53 opposite the upright 41.

In order to turn the right hand conveyor, as in Fig. 10, a shaft 54 is extended through the tube 5I and is rotatably mounted in the outer end of the tube, as by a gland 55. The inner end of the shaft 54 projects beyond-the tube 5I, the shaft 54 having fixed thereto as by lock nuts 56, a centering gear wheel 51, particularly illustrated in Fig. 14. The centering gear wheel has radially extending fingers 60 and an annular series of openings 6I for alternately receiving the pointed ends on the teeth 62 of a clutch member 63 preferably formed integrally with the tube 5I, as shown in Fig. 10, and the pointed ends of teeth 64 on an oppositely disposed clutch member 65 suitably fixed, as shown in Fig. 14, to the innergend of the shaft 45 supporting the lower left hand pair of aligned sprockets.

The shaft 54 is extended outwardly and to the right, Fig. 10, beyond the housing I and terminates in the suitable knob or handle 9 forming the exterior conveyor actuating mechanism.

When, therefore, the machine is in the condition illustrated in Fig. 10, it will be apparent that the centering gear wheel 51 is shifted to the right in such a manner that its openings 6I receive the pointed ends of the tube clutch member 63, and that therefore, rotation of the conveyor acmounting for the various parts of the vending l tuating member 9 not only rotates the shaft 54, but through the centering gear wheel 51 and tube clutch member 63, the lower right hand conveyor sprockets are rotated to move said right hand conveyor.

Engagement of such sprockets with the conveyor pockets moves those pockets in the direction of rotation of the actuating member 9, and the articles of merchandise viewed through the panel 1 are moved in such a manner that a customer may position the desired article in back of the door |1 below the panel |5, which is in dispensing position for that particular article.

It may happen, however, that the article the customer desires to purchase is in a pocket in the left hand conveyor. In order, therefore, for the article to be positioned in dispensing position behind the door I6 below the panel I4, an arrangement is provided, of which the shifting lever 20 forms a part, for shifting the conveyor actuating mechanism into engagement with the left hand conveyor for acting on that conveyor independently of the right hand conveyor.

This arrangement is shown in Figs. 4, 5, 8, 9, 10, and a part thereof in Fig. 14, and comprises a substantially vertically arranged supporting partition 15 disposed between the partitions 49 and 52, the lower end thereof being suitably hinged, as at 16, to the bottom member 50 of the framework. A set screw 11, Figs. 6, 7 and 14, is extended through the partition 15 at a point therein in alignment with a solid annular portion on the centering gear wheel 51 in such a manner that movement of the partition 15 to the left, as in Fig. 10, effects engagement between the set screw and the centering wheel to shift the centering wheel to the left out of engagement with the clutch member 63 on the tube 5| and effects engagement of the pointed teeth on the clutch member 65 on the shaft 45 of the left hand conveyor with the openings 6| in the centering gear wheel. Movement of the partition 15 to the right, as in Fig. 10, returns the centering gear wheel 51 to the position shown in Fig. by means of engagement with the centering wheel of a set screw 18 oppositely disposed in relation to the set screw 11 and mounted in the upper oiset end 19 of an arm 80 fixed to the partition by suitable fastening devices 8|, the olset end of the arm 80 admitting of free rotation of the centering wheel 51 between said arm and one side of the hinged supporting partition 15.

The shifting lever 20 for effecting this movement of the hinged partition 15 and consequent shifting of the conveyor actuating member 9 into engagement with the desired conveyor consists of a rod or bar 85, Fig. 5, suitably fixed preferably to the upper forward corner of the partition 15, the bar 85 extending upwardly behind the cover 4 and between the conveyors to a point in the framework interiorly of the housing above the doors I6 and I1 where said bar is turned laterally outwardly for extension through a suitable slot or the like 86, Fig. 1, to terminate in the shifting lever handle 20.

With the construction thus far described, it is 'apparent that a customer approaching the machine may view a series of articles to be vended and choose a single article in either conveyor and place the chosen article in position to be dispensed by manipulation of the conveyor actuating member 9 and the conveyor actuating member shifting lever 20.

In order to dispense the article or eject the chosen article from dispensing position, it is necessary to drop a genuine coin of proper denomination in the slot I8 in the cover 4 of the machine. A conventional coin selector or spurious coin detector 90, Fig. 4, is mounted within the cover 4 immediately in back of the coin slot I8. This coin selector automatically determines whether or not the coin presented to it is of a type required to purchase a single article contained in the machine and, if the coin presented is spurious or of improper denomination, that coin is dropped into the chute 9|, Fig. 4, through which it travels to an outlet 92 from whence it is dropped into the trough 93 at the front of the machine adjacent the delivery opening I3 in such a manner that the person -presenting the spurious coin may have it returned to him.

If, however, the coin presented is genuine and of proper denomination for which the machine is designed, the selector 90 drops such coin into the chute 94 through which it is delivered to a receiving channel 95, Figs. 6 to 9, substantially at the upper forward corner of the hinged supporting partition 15.

In order to compensate for hinging the partition 15 and still admit a genuine coin to the receiving channel 95 in either of the shifted positions of the partition, the chute 9| is preferably xed in position by suitable connection with the framework and a bracket 96, Fig. 4, is preferably fixed to the chute 9| and the upper end of the chute 94 is suitably pivotally mounted as indicated at 91, to the bracket 96, the lower end of the chute 94 being in engagement with the receiving channel 95 on the hinged partition. Shifting of the partition 15 is therefore possible without disconnecting the chute 94 from communication therewith.

The proper coin having been presented to the receiving channel 95 and the desired article having been selected and placed in dispensing position, it is then only necessary to actuate the coin controlled dispensing mechanism lever I9 to dispense the desired article.

The numera1 I9, while designating the lever generally, may also represent a handle 0f suitable shape which is fixed at its inner end, as indicated at |00, Fig. 5, to a shaft |0| which has its outer end rotatably mounted in the housing I and right hand framework upright 53, as clearly shown in Fig. 10. The inner end of the shaft |0| is rotatably mounted in the right hand vertically disposed supporting partition 52, said end of the shaft being fixed against sliding movement in its support by suitable spacers and a head |02 on the extreme inner end thereof. Fixed to the inner end of the shaft I 0| is a forked arm |03, Fig.' 13, which extends rearwardly of the shaft |0| and which is normally positioned in horizontal relation to the framework. A spring |04 has one end thereof fixed to the rear end of the arm |03, the other end of the spring |04 being xed to a lever |05 preferably on the inwardly tapering central portion |06 of the lever |05. The upper end of the lever |05 extends upwardly substantially perpendicularly relative to the shaft |0| and is pivotally mounted on said shaft between the tangs of the forked arm |03. The lower end of the lever |05 extends downwardly in substantially perpendicular relation to the shaft I 0I and in inwardly spacedv relation thereto relative to the partition 52, this lower portion of the lever |05 having an elongated slot |01 therein for slidably receiving a laterally eX- tending lug |08 fixed to the lower end of a lever arm |09. The upper end of the lever arm |09 is pivoted, as at I I0, in downwardly spaced relation to the upper rear corner of the hinged partition 15, as shown in Figs. 6 and 1, and has xed thereto a lever arm I I I, which extends forwardly relative to the hinged partition 15 to a point adjacent the forward upper corner of the hinged partition 15, as also shown in Figs. 6 and '1.

Movement of the lever arm |09 is normally in opposition to a spring II2 which is suitably xed, as particularly shown in Figs. 6 and 1, to the lower end of the arm |09 and to the hinged partition 15.

Actuation of the lever handle I9 in the intended downward direction rotates the shaft in an anticlockwise direction to pivot the forked arm |03 upwardly, as shown in Fig. 13, and the slotted lever |05 substantially to the right, as shown in Fig. 13. Movement of the slotted lever |05 to the right pivots the lever yarm |09 to the right to eifect pivoting of the lever arm in a downward direction, the arm III being free to move downwardly from the position shown in Fig. 6 into engagement with a stop lug I I3. This stop ||3 consists of a laterally turned flange on the upper end of a lever II4, Figs. 8 and 9, the lower end of which lever is pivoted, as at ||5, to the forward portion of the hinged partition plate 15 on the side thereof opposite the arm I I I. The stop I|3 is adapted for movement, in an arc of a circle having substantially the radius of the length ofthe lever ||4, in response to pivoting of the lever 4, in a recess ||6 in the edge of the partition plate 15 but is normally retained in retracted position in the recess by the spring I|1 which is suitably i'lxed to the lever ||4 and to the hinged partition 15. The lever ||4 has a rearwardly extending boss |I8 adjacent the stop 3, which boss is provided with an inwardly extending lug I I9, the rear end of which is shown in full lines, Figs. 8 and 9, and the front end of which is shown in dotted lines in Fig. 6. The lug ||9 is adapted for limited movement in an opening |20 formed in the hinged partition 15, the lug ||9 frictionally engaging the inner face of a plate |2| which forms a downward extension of one wall of the coin receiving channel 95, which plate I2| is suitably spaced from the ad jacent side of the hinged partition 15 to provide adequate space for the passage of a coin, such as a nickel, therebetween.

Assuming that the lever handle I9 has been actuated to move the arm III downwardly into engagement with the stop I3, and assuming that the stop is in its normal retracted position, further downward movement of the arm I| I is prevented. It may happen that the operator of a machine is impatient or careless and an attempt might therefore be made to force the lever handle I9 further downwardly. This is permitted to a limited extent by movement of the forked arm |03 in an upward direction against tension of the spring |04, the spring |04 being of substantial strength and forming a shock absorber for protecting the machine against misuse before it is prepared for dispensing merchandise therefrom.

When, however, a coin, such as a nickel, is dropped in the coin slot I8 and is accepted by the coin selector, the coin drops to the channel 95 and is deflected laterally rearwardly by a boss |25, Fig. 6, which boss is utilized for spacing the plate |2| of the coin channel to provide space through which the coin may travel. De-

flection of the coin brings it into engagement with the inner face of a tapered boss |26 xed to the inner side of an arcuate cam |21 mounted adjacent the forward end of the arm III and traveling when the arm I|| is pivoted downwardly in a path formed by the inner arcuately shaped surface |23 of the coin channel plate I2|. The tapered boss |26 spaces the cam |21 from the partition 15 in such a manner that the cam |21 forms an outer wall to cover the coin and maintain it in its proper downward path.

Travel of the coin in a downward direction is also limited by the lug ||9 which cooperates with the tapered boss |26 in temporarily conning the coin. The coin, however, being in the position indicated at |29 in Fig. 6, and continued pressure in a downward direction being applied to the arm III, the tapered boss |26 engages the coin and tends to force it down-V wardly and the coin therefore forces the lug ||9' outwardly. Outward movement of the lugl I'|9 forces the stop ||3 outwardly out of retracted position since movement of the lug causes' the lever |I4 to pivot outwardly against tension of the spring ||1, the result of which is to remove the stop ||3 from stopping engagement with the arm thus permitting the arm II| to continue its downward movement to force the coin further downwardly, the coin then dropping to the position indicated at |35 in Fig. 9. This position of the coin is maintained by lodgment of the coin on a pair of inwardly turned stop members |36 and |31.

The stop member |36 consists of an inwardly turned flange passing through an opening |38 in the partition 15, which flange is reciprocable in the opening |38 in response to pivoting the arm |39, of which it forms a part, about the pivot point |40, such pivoting being effected by downward pressure on the arm I4I against rotation of the spring |42 which is suitably iixed to a laterally turned shelf 43 formed on the arm |4| of the stop member |36.

The stop member I 31 comprises an inturned flange on a lever |45 which is pivotally mounted. as at |46, on the hinged partition 15 and which reciprocates within a guide |41 suitably fixed to the partition 15. Reciprocation of the lever |45 is effected by actuation of the arm |48, the rear end of which is oiset inwardly into an opening |49 in the partition 15, said end of the arm |48 being xed to the bar |50 on the other side of the partition, as shown in Figs. 6- and '1. The bar |50 is pivotally mounted on the partition 15 by a pin or the like |5I, the upper end of the bar |50 having an arcuate slot |52 therein for receiving an inwardly extending lug |53 adjacent the rear end of the arm With this construction, it is apparent that downward movement of the lever handle I9, while moving the arm downwardly, also pivots the upper end of the bar I 50 rearwardly and the lower end thereof forwardly to move the arm |48 on the other side of the partition forward and also move the stop member 31 forwardly to securely retain the coin in the position illustrated in Fig. 9, assuming that the stop member I 36 is in its normal rearward position in the opening 38 which is occasioned by normal action of the spring |42.

t is desirable that, once actuation of the machine has been started, such actuation should be completed before admitting of another actuation or attempted actuation of the machine. To this end, the rear face of the arcuate cam |21 is provided with a series of ratchet teeth |55 adapted to receive one end of a dog |56 pivoted to the hinged partition 15 in alignment with the ratchet teeth |55 and held in operative position relative thereto by the spring |51 secured to the dog and to the partition 15. The manner of employing this arrangement is illustrated in Fig. 7, wherein the arm is shown in down position and the dog in engagement with one of the teeth of the cam 21 for preventing upward movement thereof without fully completing downward movement of the arm Upon such completion of downward movement of the cam |21, the dog rides over the top |58 of the cam |21 whereupon it is free to pivot upwardly and permit upward movement of the cam |21 on the arm to repeat actuation of the arm. However, after upward movement is started the dog engages the teeth to prevent downward movement until after the lug ||3 has returned to normal locking position.

It was stated earlier in this specification that one of the features of this invention is to provide for collection of the coin only upon delivery of merchandise from the machine and that the coin is returned to the operator when no merchandise is in the pocket in dispensing position relative to the delivery outlet of the machine.

When, therefore, no merchandise is in a dispensing pocket, the stop member |36 remaining in the position shown in Figs. 8 and 9 and forward movement of the arm |48 moving the stop member |31 to the position shown in Fig. 9, rearward movement thereof in response to raising of the operating lever handle I9, moves the arm |48 rearwardly and the stop |31 rearwardly to the position thereof shown in Fig. 8. Such an arrangement forms an incline for the coin and permits it to roll by gravity down the forwardly directed channel |60 and out into the dispensing outlet in the auxiliary cover I of the machine for return to the operator.

On the other hand, when a merchandise containing pocket is arranged in dispensing position,

and the proper coin is in the position shown in Fig. 9, the stop member |36 should be in the position shown in Fig. 9 and the stop member 31 should be moved to the right, relative to Figs. 9, in oppositely disposed relation to the arrangement shown in Fig. 8- to the end that an incline may be formed to permit the coin to roll rearwardly relative to the machine and to the left relative to Fig. 9 for engagement upon the deflecting member |'6|, Figs. 6 and 7, for subsequent passage into the coin box |62.

This collection of the coin is accomplished by the arrangement for ejecting the merchandise from the pocket in cooperation with the dispensing doors of the machine. The article ejecting mechanism is particularly illustrated in Figs. and 10, wherein |65 and |66 each designate ejecting members having forwardly directed fingers |61 projecting therefrom, which are engageable within the openings 28 of a merchandise containing pocket on either of the conveyors when that pocket is aligned with the ejecting member in front of one of the doors |6 or |1 of the machine. The outer end of each ejecting member is slidably mounted in a track |68 mounted on the inner faces of the respectively uprights 41 and 53. The inner ends of both the ejecting members are provided with a boss |69, Fig. 10, having fixed thereto in transverse relation to the ejecting members and in parallel relation to the fingers thereof, a rod |10. This rod |10 on both ejecting members is slidably guided in a bracket |1| and is adapted for reciprocation forwardly and rearwardly insaid bracket when the ejecting members are reciprocated ir a similar manner to force the fingers thereof forwardly to dislodge an article indicated by dotted lines |12, Fig. 5, from one of the pockets which, in this instance, may be designated |13.

In order to move the ejecting members an arrangement is provided which is particularly illustrated in Figs. 8 and 9. This arrangement consists of an actuating plate |15, which has a lower arm |16 pivoted to the hinged partition 15 below a substantially central, upwardly extending opening |11 in the hinged partition. The arm |16 of the plate curves forwardly and then rearwardly around the shaft 54 extending through the hinged partition, as shown in Fig. 10, one side of which arm terminates in a boss |18, and the other end of which arm extends upwardly to terminate in an upstanding ear |19 which is formed by extending the boss |18 upwardly to cooperate in forming the ear |19. The boss |18 and the upper portion of the arm |16 bound a slot in the plate |15, said slot extending diagonally upwardly from the boss |18, then terminating in a. substantially vertically disposed end. This slot 80 is adapted to receive a lug |8| on the inner face of the arm which lug passes through the hinged partition 15 and through the plate |15. The normal position of the arm being in up condition, as shown in Fig. 6, the lug |8| thereon is in position relative to the plate |15, as shown in Fig. 8, that is in the upper end of the slot |80. Under such conditions, the plate is in retracted rearward position, shown in Fig. 5, that is, in engagement with the left hand merchandise ejecting member |66.

Movement of the lever handle I9, therefore, in a downward direction, moves the arm I in a downward direction and pivots the plate |15 from the position shown in Fig. 8 to that shown in Fig. 9, the lug |8| on the arm I riding down the slot |80 in the plate |15 and forcing the plate |15 forwardly. The ear |19 on the plate' |15 is adapted for engagement with the rear face of the inner end of each of the ejecting members |65 and |66, such engagement being shown at the point in Fig. 5.

Depending upon the position of the hinged partition 15, therefore, actuation of the lever handle I9 moves one of the ejecting members |65 and |66 forwardly in the track |68 and the bracket |1| to eject an article of merchandise from out of a pocket on the conveyor aligned therewith.

In order to provide for ejecting the merchandise only in response to actuation of the lever handle |9, a lock is provided for each of the ejecting members which is actuated by the ear |19 on the plate |15 only when the plate is moved in response to actuation of the lever handle |9. These locks are duplicate in character and each of them consists of a pair of arms |86 and |81, Fig. 5, which are pivoted at their juncture |88 to the inner end of each of the ejecting members |65 and |66. The arm |86 of each of the locking members has a. dog |89 extending laterally therefrom and adapted for engagement with an upstanding ear |90 on one side of the bracket |1|. Thearm |81 of each of the locking members extends laterally of the pivot |88 into the path of the ear |19 on the plate |15, engagement of the ear |19 pivoting the arm |81 forwardly to remove the dog |89 from engagement with the ear |90 for permitting the ejecting members to move forwardly in response to actuation by the plate. These locking members are each normally retained in locking position by a spring |9| winch tends to hold the locking memy bers in the condition shown for the left hand ejector mechanism in Fig. 5. The spring is prevented from pivoting the locking member beyond the position shown by a downwardly extending ear on the arm |81 on the locking member which is engageable with the forward face of the ejecting member.

It will thus be seen that should an attempt be made to move the ejecting members forwardly, for example, by attempting to actuate the same without manipulation of the lever arm I9, the ejecting members will be locked against such movement.

As was above pointed out, one of the features of this machine is to collect the coin only when merchandise is delivered, thus providing a fair machine for both purchaser and vendor. This arrangement is illustrated in Figs. 4 and 12 wherein the doors |6 and |1 are illustrated, such doors being shown to be hinged over each of a pair of outlet openings |92, which openings are cut in a bracket |93 having its ends suitably fixed to the framework uprights, the bracket |93 extending forwardly of the conveyors and the remainder of the coin controlled mechanisms.

The doors are opened and closed by rods |94, Fig. 5, fixed thereto and to the ejecting members |65 and |66 respectively, i. e. in response to actuation of the lever handle I9, the doors are opened ,to permit an article in a pocket aligned therewith to be ejected when the ejecting members are moved forwardly, the doors again being closed when the ejecting members are moved rearwardly.

In order, therefore, to collect the coin immediately -upon opening of either of the doors I6 or I1, a pair of rods |95 and |96 are provided, which rods are rotatably mounted in bearing members |91 and |98 on the bracket |93 above each of the doors. The arrangement is substantially the same for each door and the rod |95, for example, has one end |99, Fig. 2, thereof turned downwardly and adapted to be pivotally moved in response to rotation of the rod through a slot 200 in the bracket aligned with a center partition 20| in each of the panels of the doors I6 and I1. The end |99 of the rod |95 extends downwardly substantially to the bottom of the door and therefore lies in the path of an article of merchandise being ejected from a pocket in back of that. particular door. The rod |95 is therefore rotated when an article of merchandise engages the end |99 thereof and pivots the same in response to pressure applied by the ejecting members. The other end 202 of the rod |95 is turned inwardly relative to the machine and has xed to the inner end thereof a link 203 which extends through one of a pair of aligned openings in a bracket 204 xed as at 205 to the inner face of the bracket |93. The link 203 is pivoted to the end 202 of the rod |95 and a spring 206 is mounted on the link which tends to force the end 202 downwardly when the link is off the dead center position as shown for the companion link 201 in Fig. 12. The bracket 204 has a set screw 204 threaded therethrough to adjustably engage the end of the rod |95 to prevent the mechanism from stopping on dead center.

A yoke 2|0 is pivotally mounted on the adjato the pressure exerted by the springs 206 and 201. An arm 2|2 is pivotally mounted, as indicated at 2|3, on the yoke 2|0 substantially at the outer end of the yoke and adjacent the base 2|| thereof for providing the arm 2|2 with a substantial vertical reciprocation in response to pivotal movement of the yoke. The lower end of the rod 2|2 is illlustrated in Figs. 4, 8 and 9 and is seen to be engaged with the shelf |43 on the stop member |36, as by fastening devices 2|4. A stop 2|5, Fig. 4, is mounted on the arm 2|2 and a spring 2|6 is interposed between the stop 2|5 and the shelf |43 for normally urging the arm 2|2 upwardly in such a manner that downwardly pivoted movement of the yoke in response to action thereof by the merchandise moved ends of the rods moves the arm 2|2 downwardly against tension of the spring 2|6. ,l

It is here pointed out that thef-spring 2|6 is of greater strength than the adjacent spring |42 to the end that a snap action is provided for moving the stop member |31 into coin collecting position as soon as merchandise ejected by the ejecting members pivots the downturned end |99 of the rod |95, thus causing the spring pressed end 202 of the rod 95 to engage the base of the yoke 2|0 for moving the arm 2|2 downwardly in cooperation with the spring 2|6.

Another feature provided for in the present invention is an arrangement for locking the vending machine when the shifting mechanism thereof is in neutral position, that is, when the upstanding ear |19 on the ejecting member actuating plate |15 is positioned between the inner ends of the ejecting members. Such a neutral position is effected when the shifting lever 20 is substantially midway its length of travel in the slot 86 in the cover 4 of the vending machine.

In accomplishing the lock for the shifting mechanism when in neutral position, the -bar |50, Figs. 6 and '1, is provided at its upperend with a recess 220 terminating at the uppervend thereof in a tooth 22| engageable with a cooperating tooth 222 on a lever 223 pivoted as at 224 to the hinged partition 15. The lever 223 is normally maintained in upwardly raised condition out of engagement with the bar |50 by a spring 225, one end of which bears upwardly against an ear 226 on the bar, and the other end of which bears against a ange 221 of an angle bracket, the other ange of which is xed to the hinged partition 15. The movement of the lever 223 is limited in a downward direction by engagement of the ear 226 with the bottom of a recess formed by striking the `securing iiange connected with the flange 221 of the lower angle bracket outwardly from the partition 15 to pro vide a space therebetween for slidably receiving the outer end of the lever 223 therein.

Upward movement of the lever 223 is limited by engagement of the upper edge of said lever within the forked end 230 of a control bar 23|, Fig. 10, which is pivoted at its upper end to an upstanding plate 232 suitably xed and extendlng upwardly from the bracket |1| for slidably receiving the rods |10 of the ejecting members |65 and |66. The control bar 23| is normally positioned at an angle when the partition 15 is hinged in either of its ejecting member contacting positions, one of which positions is shown in Figs. and 10. Since the control bar in the condition illustrated contacts the lever 223 when the partition is moved to the left from its position shown in Fig. 10, the control bar, being pivoted, must travel in an arcuate path and when it reaches a vertical position relative to its angular position illustrated in Fig. l0, the lever 223 is necessarily depressed in opposition to action of the spring 225. Such depression of the lever 223 moves the tooth 222 thereon downwardly into the rearward path of travel of the bar |50 in such a manner that rearward movement of the bar |50 in response to actuation of the lever handle I9 effects engagement of the teeth 22| and 222 thereby locking the machine against further movement of the lever handle I9 until such time as the control member 23| has passed its vertical position and is pivoted upwardly to the left relative to Fig. to permit the lever 223 to raise in response to action of the spring 225 thereby effecting disengagement of the teeth 22| and 222 and permitting effective actuation of the lever handle |9 in dispensing merchandise from the machine.

The upper rear edge of the hinged partition is provided with a notch 233 to permit the locking bar 23| to actuate the lock 223 without becoming bound or interfering with hinging movement of the hinged partition 15.

It is desirable, when the conveyors are so positioned that a pocket thereof containing the desired article is placed in dispensing position in back of one of the door openings I6 and I1 depending upon the shifted condition of the hinged partition 15, that the conveyor and pocket thereof containing that article be maintained in stationary condition during the time the article is being ejected from the pocket. To this end, a stop plate 235 is provided as shown in Figs. 8 and 9, the upper end of which stop plate is pivoted as at 236 between one end of a bar 231 and the upper edge of the hinged partition 15 preferably to the rear of the plate |15. The lower end of the stop plate 235 has an outwardly projecting lug 238 thereon which is engageable between the adjacent pairs of teeth of the centering gear wheel 51, it being apparent that when the lug 238 is between a pair of said teeth on the gear wheel that the wheel is retained against rotation in either direction. In order to move the stop plate 235 in coordinated timing with the remainder of the vending machine, it is provided with a slot 239 for receiving the lug |53 mounted on the inner face of the arm III, which lug eX- tends through the hinged partition and engages the plate 235. The slot 239 is arranged in such a manner relative to the lug |53 that when the lever handle I9 is actuated to move the arm ||I downwardly the lug |53 rides down the slot 239 on the plate 235 and forces the same forwardly in between a pair of the teeth on the centering gear wheel 51.

The bar 231 on which the plate 235 is mounted also cooperates with the hinged plate 15 in providing a runway for the plate |15 and particularly the upstanding ear |19 thereof for limiting forward movement of the ear |19 by engagement thereof against the cross bar formed by the pin 24| connecting the front end of the bar 231 to the hinged plate 15.

As a protection against tearing the wrappers from articles in the machine, and further to prevent smearing of the interior of the machine, should those wrappers become disarranged on the articles o f merchandise, the grills 8 are provided which preferable comprise spaced rods 246 of substantially U-shape and following the contour of the bottom run of the conveyors, the rods 246 underlying the open ends of the conveyor pockets in such a manner as to retain articles of merchandise therein when the conveyor pockets are turned substantially downwardly as illustrated in Figs. 2 and 3. The ends of the rods 246 are suitably fixed to a bracket 241 which bracket is in turn suitably fixed to the uprights of the framework for the actuating mechanisms of the machine.

As a precaution against tampering with the machine, which might be attempted by a person with an implement extended through the delivery opening I3, a shield 248, Fig. 3, is provided which is positioned below each of the doors I6 and I1 behind the auxiliary cover I0 for the housing of the machine, the shields 248 preventing engagement of an implement with the downturned ends |99 of the coin controlling mechanism actuating rods |95 whereby the machine can be actuated only with the deposit of a genuine coin.

The operation of a vending machine constructed as described is as follows:

Assuming the machine to be assembled and in the condition illustrated in Fig. 1, a customer approaching the machine views the merchandise on display and intended for sale through the panels 6 and 1. A particular article of merchandise having been chosen, the selecting mechanism is actuated by actuation of the handle 9 to move the conveyors. If the article of merchandise is in the conveyor positioned behind the panel 6, the handle 9 is turned to position that article of merchandise in back of the door I6 below the panel I4. If, however, the article of merchandise is in the conveyor behind the panel 1, the shifting mechanism 20 is actuated and moved to the right away from its position shown in Fig. 1, whereupon the handle 9 is actuated to position the chosen article of merchandise behind the door I1 below the panel I5.

The article of merchandise having been placed in dispensing position, a coin, such as a nickel, is applied to the coin slot I8 of the machine. Should the coin be spurious the coin selector 90, Fig. 4, drops the coin into the chute 9| to a point 92 in the chute for ejection onto the delivery tray 93 in back of the delivery opening I3 so that the operator may have his coin returned to him. If, however, the coin is genuine, and of proper denomination, the selector drops the coin into the chute 94 where it is delivered to the coin receiving channel 95, Fig. 6. The coin then drops to the position shown in dotted lines at |29, Fig. 6, and it is then time to move the lever handle I9 downwardly. Downward movement of the lever handle I9 rocks the shaft IOI, Fig. 13, in an anticlockwise direction to rock the lever arm |09 in an anticlockwise position on its pivot ||0, Fig. 13, by means of the lever |05 Xed to the shaft |I0.

Prior to deposit of a coin in the coin slot, the stop member |I3 prevents downward movement of the arm III, Figs. 6 and '1, in response to actuation of the lever arm |09 and lever handle I9, continued downward movement of the lever handle being against tension of the spring |04, Fig. 13, in such a manner as to protect the machine against violent misuse.

When, however, the coin has been properly applied and is in the position illustrated in Fig. 6, downward movement of the arm III forces the coin downwardly by means of the cam |21, the coin at this time engaging the lug II9 to pivot the stop II3 outwardly as illustrated in Fig. 9. The cam |21 is then permitted to force the coin downwardly to the position illustrated in Fig. 9, where it lodges upon the sto-p members |36 and |31.

Downward movement of the lever handle I9 and consequently the arm III effects forward movement of the plate |15 from the position illustrated in Fig. 8 to that illustrated in Fig. 9, this forward movement of the plate causing the upstanding ear |19 thereon to engage with one of the ejecting members |65 and |66, Fig. 10, for moving that ejecting member forwardly in such a manner that the fingers |61 thereof enter a pocket aligned therewith through the openings 28 in the rear wall of the pocket to force merchandise in the pocket forwardly out of the pocket as particularly shown in Fig. 5. In this instance, the merchandise is forced out of the pocket and it engages the downturned end of the rod |95, which is similar to the downturned end |99 of the rod |96 shown in Fig. l2, to pivot the rod |95 clockwise and permit the yoke 2I0 to be forced downwardly by the end 202 of the rod |95 under expanding pressure of the spring 206, the rod 2I2 also moving downwardly. The rod 2I2 is cushioned in its downward movement by the spring 2I6, Fig. 4, yet pivots the arms IIII and |39, Figs. 8 and 9, of the stop member |36 in a clockwise direction in such a manner that the stop member |36 is positioned to the right, Fig. 9, of the coin to permit it to drop by gravity onto the deflector |6I, Fig. 6, for deposit in the coin box |62.

Should there happen to be no merchandise in the pocket aligned with the actuated ejecting member, the rod |95 will not be pivoted and as a consequence thereof, the stop member |36 will not be moved. Therefore, when the lever handle I9 is permitted to move upwardly, the arm III moves upwardly and the bar |50 moves to the right, as in Fig. 6, in response to engagement thereof by the lug |53 with the slot |52 in the bar |50. The arm |48 on the stop member |31 being in engagement with the bar |50, rearward movement of the bar |50 moves the stop member |31 rearwardly to underlie the coin at a position shown in Fig. 8 in such a manner that the coin is permitted to roll by gravity into the chute |60 for delivery to the delivery opening I3 of the machine.

When it is desired to shift the coin collecting and article dispensing mechanisms into coordinating relation to a conveyor other than that with which said mechanisms were first connected, the shifting lever 20 is moved in the only direction of movement left for it, which lever being connected to the hinged partition moves said partition in the direction of movement of the lever 20. If, therefore, the right hand conveyor were operatively engaged with the coin collecting and article dispensing mechanisms, movement of the shifting lever 20 to the left causes the hinged partition to move the centering gear Wheel to the left by means of its engagement with the set screw 11, the centering gear wheel moving into engagement with the pointed ends of the teeth on the clutch 65, Fig. 14.

Shifting movement of the hinged partition moves the central bar 23|, Fig, 10, to a substantially vertical position and causes the lever 223, Fig. 6, to be forced downwardly into the path of travel of the bar |50 to prevent its rearward movement. Since the bar |50 cannot move rearwardly, the arm III cannot move downwardly because of its connection with the bar |50 and the cam |21 therefore cannot be moved downwardly and the coin is held in the position illustrated in Fig. 6 without dislodging the stop H3. When, however, the central bar 23| has passed its center vertical position, the coin collecting mechanism is free to operate in its normal mannel` and the coin is therefore collected and the article of merchandise dispensed.

It is also believed apparent that whichever conveyor having a pocket containing a desired article aligned in dispensing position behind one of the doors I6 and I1 is maintained in that position during dispensing of the article by reason of the fact that the lug 238 on the plate 235, Fig. 14, is lodged between a pair of the centering gear wheel teeth and since the centering gear wheel is engaged with the shaftk on which the conveyor sprockets are mounted',fth,e conveyor is maintained in the chosen position during dispensing of an article from the machine.

Certain of the more important advantages of a vending machine constructed in accordance with the present invention are that the conveyors may be locked in desired position; that the coin collecting mechanism is operative regardless of which of the conveyors is being acted upon to dispense an article in a pocket therein; that a great variety of merchandise may be contained in the machine, which articles may be of different size, shape, and of a number approximately equivalent in height to four times the height of the machine; that the dispensing mechanism is locked when neither of the conveyors is properly engaged thereby; that a coin is collected only upon actual delivery of merchandise to an operator and this only when a genuine coin is presented to the machine; that the shock absorber adequately protects the machine from violent misuse; that an attractive display of large capacity is provided; and that the machine ernbodying the present invention is simply operated and is efficient and substantially foolproof in such operation.
