For purposes of orientation inthe art, the machine herein disclosed may beconsidered asan improvement on that disclosed in my copending application Serial No. 341,448, led June 20, 1940.

One general object of the present invention is to provide a novel apparatus fox'- the selective '1o dispensing of articles of diilerent varieties from a single machine. For example, the presently disclosed machine may be used for the sale of a series of diierent kinds of bottled drinks, themachine being arranged for selection by the purchaser of the particular kind of beverage which will be delivered to him when he drops his coin into the machine. Y

A more specific object of the invention is to provide a novel selective type dispensing machine 20 in which butfa single drive mechanism is required for delivering fan article orany of the series of,"

varietiesavailable. l

Another object isjto provide such a selection type dispensing` machine "in 'which the storage V25 capacity of the machine can be proportioned with great ilexibility. at the proprietors option, among a series of diirerent varieties oi articles to be dispensed. For example,` if one .particular brand of coin slot, having a novel interlock' arrangement auch that ii' two or more of the selection buttons are pushed at the same time the machine will not be cheated but will only deliver one articleof Ione of the selected varieties.

' Still another object is to provide a dispensing machine embodying a novel arrangement for stripping from a rotatable carrier in the machine,

successive articles being dispensed.

The invention also residesin various structural improvements in the machine, particularly in the carrier units and associated article-releasing mechanism, by virtue ofwhich low cost, ruggedness and effectual operation are combined. i

Further objects and advantagesoithe invention will become apparent as the following description proceeds taken in connection with the accompanying drawings in which:

system of such character that if a user elects to A40 Figs. 10 and ll are stop-motion views of one .purchase an article from .a carrier which happens to be empty at the time, although a supply of the e same variety of article is available on another carrier, one of the articles of the desired variety willbe automatically delivered to him from such other carrier. In other words, the eilect of his selection manipulation'of the machine is automatically transferred to control aiother part of the machine by virtue of`which heA will receive,

nevertheless, the desired varietyof article.

Another object is to provide a. selective type dispensing machine with a series of selection buttons, one of which should be pushed to condition the machine to deliver the corresponding variety of article when a coin is inserted-in the ,-machine. In its broader aspects, however, the

invention is, as will be readily apparent to those skilled in the art, applicable to other classes or dispensing machines. Consequently even though the particular form of the machinev shown has been described in some detail, there is no intention thereby to limit the invention to this specific embodiment, but on the other hand, I intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

As to the general arrangement of the illustrative machine, it will be seen upon reference to Fig. l that it includes a cabinet il o f rectangular cross section. The cabinet has a pair of 'front doors I I, |2 which are customarily locked, but which, when unlocked by the proprietr,'can be swung open to expose a compartment I3 (Figs. 2 and 3). In this compartment is mounted a unit, designated generally as I4, on which bottles to be dispensed are racked up in storage. To operate the machine, a purchaser punches one of a series of selection push buttons l5 to 2| (Fig. 1)- 0n a coin box 22,2. the selected button corresponding the coin'box are arranged opposite the selection buttons to designate the various kinds of drinks available) and then drops his coin in the coin slot 24 of a coin box.` Thereupon a bottle of the selected variety of beverage automatically pops out of one of the series of delivery doors or hatches 25 on the front of the machine. In the event that the machine is all out of the selected variety of 4drink his c oin is automatically vre turned to him in a return cup 23.

The cabinet III shown herein resembles in gen.. eral construction the familiar refrigerator cabinet and comprises innerand outer steel shells 21 and` 28,'respectively, separated by a layer of heat insulation 29 (Fig. 3). ATo cool to a predetermined temperature the bottled goods in the heat insulated compartment I3, any suitable well known refrigerating apparatus may be used. I'he i one shown in the present instance comprises an evaporator coil 30 (Figs. 4 and 5) in the upper portion of the compartment |34 `This coil is supplied with vaporizable liquid refrigerant from a compressor-condenser unit (not shown) housed in the lower cabinet beneath the compartmentI scribed and claimed in my copending application Serial No.4 341,448 referred to above: In common with the machine illustrated in said copending application, the presently disclosed one is designed to receive the bottles in a series of generally conical groups, each group being seated on one of a series of independently revoluble carriers, and the carriers are nested down one over the other. By virtue of this arrangement a maximum storage capacity is achieved. Also in common with the machine of said copending application, the carriers in the present machine are all connected by individual slip or friction drive connections with a single power driven vertical shaft and are controlled by associated latch mechanisms so that the carriers can be stepped around to present successive bottles b thereon to the delivery stations for the several carriers, where they ar`e stripped from the carrier automatically as an incident to such movement. 'I'he machine disclosed in said eopendlng application was adapted for the dispensing of only one kind to the particular drink he wants (tickets 23 on of drink, however, while the presently disclosed machine is of the selective type and embodies a novel arrangement adapting it for the selective dispensing of a series of different varieties of drinks. Also, in accordance with'another aspect of the present invention, novel forms of carrier construction and article-discharge mechanism have been incorporated in the machine herein shown.

Turning now to the details of the presently disclosed machine, it will be observed upon reference to Fig. 4 that the unit |4 comprises a series of superimposed carriers (here shown as seven in number) 32 to 33. 'I'hese carriers are arranged for individual rotational indexing movement about a common vertical axis and since they are of identical construction a description of one will suffice for all. By way of example,

the lower carrier '32 (see Fig. 5) comprises a frusto conical sheet metal hood 33 fixed to a similarly shaped peripheral flange 40 on a disk shaped central web 4| integral with a hub 42. Bottle-receiving pockets are defined in a continuous annular series about the exterior surface of the hood 33 by sheet metal barrier strips 43.

These strips are doubled upon themselves in V-shape (see Fig. 3) and have small integral feet 44 on their lower edges which are spot welded or otherwise rigidly fixed to the hood. The spacing between these barrier strips 43 is such that bottles of a maximum width likely to be encountered can be received in the pockets. Of course.- this use of such a maximum width pocket aords some extra clearance for smaller bottles, but, even so, they, are properly supported i and the loss in storage capacity entailed is comholding positions.

pensated by the resulting versatility of the machine.

The bottles b are releasably held in place in the carrier pockets by pivoted detents orgates 45 as shown in Figs. 6 and '7 (see also Figs. 3, 4 and 5). These detents are-fashioned in the form of elongated sheet metal fingers pivoted on brackets 45 on the carrier by pivot pins 41 so as to swing from the bottle-holding position shown in full lines in Fig. 6 to the bottle-release position shown in dot dash lines. Contractile springs 43, each anchored at one endv to its bracket 45 and at the other end 'to a lug 45* projecting from the butt end of a finger 45, serve vto yieldably urge the detent fingers 45 into their bottle- It will be noted that when these detents are 'swung to their released positions that the bottles, which vthey previously engaged.

are freed so that they can slide outward and downward from the hood by gravity, thus affording an easy means of stripping the bottles from the carrier during dispensing.

In order to support the carriers 32 to 33 in the desired superimposed yspaced relation; (see Fig.

5) their hubs 42 are loosely joumaled on a ver'- tical drive shaft 49 having collars 59l pinned to drive 43 isfrevolved and this shaft is. in

provided between the respective carriers and the -drive shaft 4l, these connections being in the v5 present instance.. oi' thei'riction type and constitutedsimply by the i'rictionally engaging surfaces between the tops of the collars 5I) and the opposed bottom end surfaces of the carrier hubs 42. To augment the weight oi the carriers in holding these mating frictional surfaces together, helical compression springs 51 are provided (Fig. 5). between the upper sides of the respective caro riers and the lower sides oi the next adjacent iixed collars. The spring 51, which presses against the uppermost carrier 38,is held in position by an extra collar 50.

As noted above the drive connections 42, 50 serve to yieldabiy urge all of the carriers to ro" tate when the shaft 49 is revolving. In order that the desired selective type of ,operationmay be achieved, latch means is provided forfholding all but a selected one of the carriers against rotation, when a delivery is being made, so that only this selected carrier will turn to deliver a bottle. These latch means also cooperate with the drive mechanism to eect a stepeby-step motion of even theselected carrier so that it will,

upon each actuation of thecontrols, permit 'an advance of only onestep for the selected carrier. In the present instance a latch mechanism 5I is provided for each carrier, these latch mech'- anisms being iixed to an upright angle iron 59 at the rea'r of. the cabinet (see Figs. 5 and 3).

Referring to the latch mechanism 58 for the lower carrier 32 (Fig. 9), which will serve 'as an.

example for all since they are all alike, it includes a sector shaped latch plate 60 pivoted by a pin 8| on the upright 59 to swing into andiout oi engagement with notches 62 in the lower edge of the sheet metal carrier hood i9. Retraction of the various latch plates .60 is accomplished by corresponding solenoids, designated as 63* to.

63' for the respective latch mechanisms(see Flgfj). Each of these solenoids has a vertical armature (not shown) connected to the -outer corner of its associated latch plate by a link 84 (Fig. 9).` When thesolenoid is deenergized the link `5 4 drops down and the latch plate is 5 gravitationally urged into engagement with the y periphery ofthe associated carrier. Upon energization of the solenoid the latch plate is shifted from its engaging position shown in full lines in Fig. 9 toits disengaged position shown in dot vdash lines. After thelatch is thus disengaged the carrier hood 39 can start to rotate, whereupon the nose of the latch plate 60 rides along the" lower edge of the hood. With the presently disclosed controls, the solenoid is again deenergized during the progress of the carrier so that mounted on the pivot pin 6l ofl the latch plate 60, and connected to the latter, and arranged to enter betweena pair 'of stationary jaw c'ontacts 65 insulatingly mounted on theupright 59. 'Ihe blade 85 thus swings with the `latch plate 'I'hese springs are interposed .l A assures 3 tui-n, ari-@ngen teyieidsbly une au of the en?Av riers l! to ll to rotate.V For this purpose in divldual slip or friction drive connections are .so that the switch lsclosed wben'the latch is reand converselyfis 4 `irengsgeii..Iiswillhe appearingreater 'detail, these motor' switches serve to' retain the carrier drive motor. energized so long as one latchesl It is released. Accordingly. in

' starting the 'machineto deliver a bottle,'when any one of the latch-releasing solenoids "Lto, 1 is even substantially` momentarily its corresponding motor switch will be closed the motor started so that the carrier rotation `is initiated and maintained until the released latch reengages. Hence, even 4though the latchreleasing solenoid becomes deenergized after such l5 'momentary .energizatiom the -latch will 'be rez tained disengaged (by the edge' of the hood4 along which ,it rides) and the motor switch will remainA clod, until the next notch 52 on ,the carrier hood reachesthe'latch. Then `as the latch drops into this next notch the motor switch is simultaneously opened and the motor stopped,

thereby arresting further rotation of the carrier. In this `general manner the carriers can be notched around step-by-step upon successive actuations of the control mechanism.

Discharge-*ofthe bottles b from thev carriers 32 to is accomplished at the delivery stations by a series of stationary dogs 81 (Figs. 2, 3 and 5). These dogs are, in general, arranged .to a'ctu-l ate, to their bottle-releasing positions, successive ones oi.'- the detents 45 presented thereto during the rotation ofthe carriers' so that the bottles b are released to slide-from their carrier pocketsr vone by one as the carriers are stepped around.

Upon reference to Figs. 5' and lV it will -be seen that each of the dogs 61 is fashioned. from a strip of sheet metal of distended V-shape and is fixed with its nose portion 67* (Figs. 6 and "l) disposed to project into the path of the for- 40 wardly projecting lugs 45Il on the detent fingers 4I. Innormal operation the .carriers rotate in a clockwise direction (as viewed from the top of the machine). Hence, during each step of advance for a carrier, one of its detentsV 45 will be 45. raised as its lug a rides under thecorresponding dog 61. As the carrier moves on in the next step o i advance', the4 detent linger 45 swings still vfaridfier to the right (as viewed in Fig. 6)', thus sliding under the nose Sltof the dog and moving free of it, to snap back into its normal position while the next detent lug 45 come: into contact with the dog to elevate the correspond'- ing detent.l` Y

By mounting the dogs 6l on'the cabinet door II (See Fig. 2) they are all automatically moved into a position remote from the carriers whenever the cabinet vdoors are'swung open. In this way they are removed from operative relation.

' with the carriers so that the latter can be freely rotated` during reloading without danger Yof having one of the dogs inadvertently strip the bottles fromits carrier. Y effectual interlocking system. Furthermore, this system is one which does notrequire any electrical interlocks between the dogs and the switches which control rotation of the carriers during reloading of the machine since the cab*- net simply cannot be opened for reloading with. out at the same time swinging the dogs 61 into inoperative position.

At the delivery stations for the various carn riers 32 to 38 hatchways or .discharge openings are provided to receive the successive bottles stripped from the carriers -as they are' stepped 'l around. For *this* purpose a long vertical slot ed when the latch This forms a very simple and Il is formed in the cabinet door Il (see Figs. 2 and 3) and in it is nxed a hollow sheet metal housing 59, which projects from the front of the cabinet (see Fig. 1). Outtumed flanges 19 on the inner edges of the side walls of this housing (Fig. 3) are fixed to the inner face of the door Il to hold the housing in place. The interior of the housing is divided into a series of discharge throats 1l (Fig. 5), one for each carrier, by a corresponding series of inclined partitions or slides 12. These slides are inclined at substantially the same angle as the surfaces of the carrier hoods 99 and form, in effect, continuations thereof down which the released bottles can slip. The trap doors 25 are of simple rectangular form and are pivoted at the lower edges of the corresponding slides 12 by pintles 19. The series of trap doors 25 form, in effect, the front wall of the housing I9.

Each of the trap doors 25 (see Fig. 8) is yieldably urged to its closed position by a torsion spring 14 encircling the Dintle 19.

Whenever a bottle b moves down one of the` slides 12 it thrusts open the corresponding trap door v25 and swings the latter down to the full open position shown in dot dash lines in Fig. 8. Engagement of the lower edge portion of the door with the underside of the slide limits the opening of the trap door to an angle at which it is alined with the slide. As the bottle moves down the opened door it vcomes to rest against a flange 15 at the free edge of the door (see Fig. and remains in thisconvenient delivery position untilpicked up b`y the purchaser. soon as the bottle is removed the door is snapped shut by its spring 1I. Desirably the top surfaces of the slides 12 and doors 25 are covered by rubber mats 16 and 11, respectively, so as to limit the speed of the bottles as they emerge.

In order to disable the carriers 92 to 59 against further rotation after they have been notched around to predetermined stop" positions, a series of carrier switches Sno to Sie is provided (Fig. 5). These switches are mounted on the upright 59, which carriesthe latch mechanisms 59, and are all identical in construction. Upon reference to Fig. 9 it will be `observed that the switch Sm, there shown for the lower carrier 32, comprises a resilient tongue 19 carrying a central double `contact point 19, the tongue being normally flexed downward to maintain this contact point closed against a lower contact point 99. A cooperating pin 9| on the carrier hood 39 is arranged to ythrust the tongue 'I9 upward, upon contacting it, v-so as to open the contacts 19, 90 and close the contact 19 against an upper contact point 92. As will hereinafter appear in greater detail, such actuation of one of the carrier switches serves to disable its carrier against further rotation during` the normal dispensing operation.

Unauthorized removal of bottles from the machine is effectively prevented even though tle trap doors 25 on the front are unlocked and can be easily pried open. In this connection it should be noted that when one of thecarriers is fully loaded (see Fig..10)and in its starting position ready to begin dispensing, it is disposed with the outer end of one of the pocket-separation barriers 43 centered at the discharge opening in the door Il. When in such position there is insufflcient clearance for a bottle to be pulled out 52* is provided in the carrier periphery intermediate two of the regular notches 52 so that the to be released from the carrier.

through the discharge opening. An extra notch y free a bottle b for delivery.

:,srsaiss` latch 5I can hold the carrier effectually in this initial or starting position. Upon the rst release of the latch to notch the carrier around, the latter moves only a half-step, in other words,

u from the position of Ilig. 10 to that of Fig. 11.

'Ihis movement' is, however, sufficient to present a bottle vto the discharge opening and causes it After this bottle is discharged there is, of course, simply' an empty pocket presented in the discharge opening. Upon each succeeding actuation of the carrier latch the carrier is moved around` a full step but after the resultant delivery of each bottle an empty pocket is always presented to the discharge opening'so there is no danger of the machine being robbed through this opening. The initial half-step arrangement takes care of the only instance in which unauthorized removal of a bottle 'leasing solenoid of the corresponding carrier will be released more or less momentarily. Release of the latchcauses the drive motor to be .ener-.- gized through closure of the corresponding motor switch, as heretofore noted, so that the released carrier starts to turn and hence the latch, riding along the edge of the carrier, stays retracted until it drops into the next notch. This reentry of the latch not only positively stops the carrier but also shuts down the'motbr. Each such step of advance causes the corresponding dog 91 to In addition to this general cycle of operation it shouldbe observed, by way of synopsis before proceeding to the details of the controls, that the system also provides for the following special features:

(a) Several of the carriers can be loaded with the same variety of beverage and the circuits pre-- liminarily set up by the proprietor so that when the stock of bottles on one of these carriers is exhausted, the effect of actuating its selection switch, will automatically be transferred to another of the carriers loaded with the same beverage so that atome win be delivered from the latter.

(b) A simple electrical interlock is provided between the,various selection push buttons i5 to 2i so that if an unscrupulous person attemptsgenerally in item (b) above as, for example, by

the well known mechanical interlocks between the push buttons so that only one can be depressed at a time. Thesimple electrical system herein shown has, however, the advantage of cheapness and in addition increases sales somewhat ln that people who would not otherwise purchase a bottle, except for the apparent possibility of defeating the machine by pressing several buttons,l will be goaded into expending at leastone coin. Despite any such unscrupulous action by the purchaser, and it may in fact at times be accidental, themachine delivers a bottle with scrupulous honesty.

Other exceptional features for which provision is made in the present selective type control system, "but which have also been incorassaisa porated in the somewhat simplernon-selective mentioned above, are:

(a) Provision is made for free rotation of the various carriers by the drive motor during reloading so as to speed up thisoperation.

(b) If desired anyone or more of the carriers can be initially cut out of service so that it the bottles on them have not been previously chilled they can be withheld from sale for a suitable length of time in the refrigerated cabinet.

(c) The carriages can be initially positioned so that they can only be stepped around a fraction oi' a revolution. In this way. a portion of the load of bottles on each carrier can be withheld from sale for further cooling or, if only a limited number of -'bottles are available for loading, that condition is taken Icare of by this same type of initial adjustment.

In the control circuits shown (Fig. 12) the motor switches Sio to Sie and the carrier switches Sao to Sie will be familiar, having been previou'sly identified. Also included in this system are a sexies of selection switches Sao to Sie arranged to beactuated by corresponding ones of the selection push bottoms l5 to 2| referred to above. These selection switches are of the twoposition type and each embodies, a movable contact 83 to 89, respectively, which is normally biased into closed position against their back contacts 9|) to 98,`respectively. 'Upon actuation of the selector buttons l to 2| the corresponding movable contacts are shifted to close against what may be termed the forward contacts 31 to |03, respectively. Also included in the control system is a set of combination switches S40 to Sie, these switches being of the double-pole double-throw tumbler type and are mounted on a panel l|04 (see Fig. 4) in the back of the cabinet compartment I3 so as to be inaccessible except when the cabinet doors are open. Also mounted within the cabinet is a set of latch-release switches S50 `to S56, these switches being of the single-pole tumbler type and mounted on a switch box |05 within the cabinet (see Fig. 4). On the same switch box is mounted a refill switch Se which also is a single-pole tumbler switch. The coin box 22 and the associated coin control switches may be of well known standard form. In the present instance the control system in Fig. 12 indicates a coin switchCS adapted to be closed generally momentarily upon the insertion of a coin or check in the coin slot of the .coin box. Also included is a lockout coil LC adapted to be energized when a lockout relay LR picksvup. When the' lockout ,coil LC is energized the coin box is conditioned to return coins, inserted in it, to the coin return cup 26. A pilot light PL, in shunt with the lockout; relay LR. indicates that the lockout coil is on. Current for the drive motor 53 andfor the various control devices, etc., is furnished from supply lines Li, La which may be plugged into any suitable source of current such as an ordinary lighting system.

Operation with different variety of beverage on each carrier As to the operation of the control system (Fig. 12), it will rst be assumed that all of the carriers 32 to 3 8 have been filled with bottles, that all of the bottles are chilled ready for sale and that all of the carriers have been positioned stop positions. Further it will be assumed that the proprietor has placed a different variety of In such casel bottled goods on each carrier.

. the proprietor will have shiftedall of the combination switches Slo to Sie to their left hand positions as shown in l'ig.`12. The cabinet is, of course, closed and locked. For convenience oi' designation, it will be assumed that bevetages A, B, C, D, E, F andG are racked up. on the carriers 32 to 33, respectively.. Underv these circumstances if a purchaser wishes to obtain a bottle of beverage A he presses the selection button 2|, thereby shifting the selection switch Sao to the left (as viewed in Fig. 12) and drops a coin in the coin slot. Thereupon the coin switch CS is momentarily closed, thereby energizing the latch-release solenoid 83'* (through a circuit L1-|08-CS-|01-63'-|08 'Sm |09 Sio- ||||-9'|83 (S30- La) so that'the latch releases the .corresponding carrier 32 and also closes the motor switch Sio to energize the drive motor I3 (through a cincuit L1-S1c-|||-53-'-||2-'L:). The carrier 20 thus starts to revolve and continues this revolving motion until the now deenergized latch drops into the next notch on the carrier, thereby opening the motor switch Su and positively stopping the carrier. During this step of advance a bottle of beverage A from the carrier 32 is, of course, ejected from it by the corresponding dog 6l as .previously described.

It may be that the next purchaser will want a bottle of beverage C from carrier 34. In such case he makes his selection by pressing the corresponding button I9 to shift the selection switch Ssn and then drops his coin in the coin box to close the coin switch CS momentarily. Thereupon the.latchrelease solenoid |53c is energized in the same general manner as described above and the motor switch Si: closed to start the motor. As a result the carrier 34 is .advanced one step to deliver a bottle of beverage C from it. This operation is repeated from time to time for various carriers until they have been notched around to thelrK/,iinal or stop positions. As soon as one of the carriers reache's its stop position it opens the corresponding one of the carrier switches Szo to S28. Since these carrier switches are included in the solenoid energizing circuits previously traced it will thus be Vclear that opening of them disables the latch of the corresponding'carrier against subsequent release so that thecarrier can move no farther.

The operation described above presupposes that the person making a purchase from the machine will understand it well enough to press one of the selection buttons I5 to 2| as a preliminary to inserting a eoinin the coin box 22. AThe control circuits are arranged so that if he should, however, fail to do so, the coin will be automatically returned to him in the return cup 26 (Fig. 1). To this end thelockout coil LC (Fig. l2) is used, this coil being arranged in the coin box in the conventional manner and being adapted when energized, to cause the diversion of a .coin inserted in the coin box to the return cup. Upon reference to the wiring diagram in Fig. 12 it will be' observed that whenever all of the selection a full revolution away from their predetermined 7| switches Sao to Sas are in their normal positions as shown that the lockout relay LR is energized (through a circuit L1| |3LR||4||5 Sao-Sas-Ss-Ssa-San-Sai-Sso-Im Conse.. quently the lockout relay LR remains energized until one of the selection switches Sio' to Su is actu-ated and as a result the lockout coil LC also remainsenersized, being` connected across the l supply lines Li, La by the relay LR. As soon. however, as one of the. selection switches is' actuated the energizing circuit for the lockout relay LR is interrupted so that it drops out and deenergizes the lockout coil LC.

The lockout coil LC also serves to return a prospective purchasers coin to him when the conhas reached its stop" position and its switch v Sie shifted to the right (as viewed in Fig. 12). In such case if the purchaser actuates the corresponding selection switch Saa the lockout relay LR will remain energized (through a circuit L1| |3-LR-S4o-I IS-Sn-I il S4@ ||3 I 03-88 (S36) -S:5S34-S3a-S32-S:1-S3o-1n) so that the coin is automatically returned. In the same way if any of the other carriers 32 to 31 have been revolved to their stop positions the shifting oi' their carrier switches Sao to Sie respectively will have set up energizing circuits for the lockout relay LR. which will be completed upon actuation of the corresponding selection switches, thereby effecting an automatic return of the coin.

Similarly if the purchaser actuates the selection switch Ss: and drops a coin in the coin slot the same carrier, namely 34,7will be notched around a step by momentary energization of its latch-release solenoid 53 (through -a circuit `L1-|Il5 -CS bottles on the carrier 34 is finally exhausted, or

in. other words, until it reaches its stop position. Thereupon its switch Si: is shifted to the right (as viewed in Fig. l2) and this conditions the circuits so that actuation of any of the selec- Operation when severalcarriers are stocked with same variety of beverage In some instances the proprietors experience may indicate that a particular brand of beverage is a best seller and in such case it is de sirable to provide an extra amount of that lbeverage in the machine. For example, if beverage C is a' best seller the proprietor may wish to provide three carriers full of bottles of that beverage and only single'carriers loaded with the other v beverages made available. IIn such casehe may,

for example. load the machine V`as follows:

tion by purchaser of any one of the selection switches Saz. Si: and S34 corresponding to the three 'earners designated as being leiden with.

beverage C will cause a bottle of beverage C to be delivered to the purchaser so long as any of it remains on any one of the three carriers 34, 35 or 35 and irrespective of whether or not the purchaser -fortuitously selects the button corresponding to the one of these three carriers which happens still to have a bottle left on it.

. In tracing out ther operation of the machine initially loaded as described above. let it be assumed ilrst of all that all three of the carriers 34, 35 and 35 are fully loaded. In such case if a purchaserA actuates selection switch Sn and drops a coinin the coin slot the carrier 34 will be notched around one step by a-momentary energization of its latch-release solenoid 53 (through a cirtion switches Sn to S34 will thereafter cause the next carrier 35 to b e notched around a step.

As to the operation of the carrier 35 after carrier 34 has been indexed to its stop position, note that when the selection switch Saz is actuated and a coin dropped in the slot the carrier 35 will be notched around a step by virtue of a momentary energization of its latch-release solenoid 53d (through a circuit L1|05CS|||1 63d S23 -\|24S43|25 S22-|20S42|2 99-85 (S32)-Sa1-Sso-L2). On the other hand 4if the purchaser happens to actuate selection switch Si: and drops a coin in the slot the carrier 35 Will again be notched around a step upon energization of its latch-release solenoid 63d (through a circuit Lie-#IOS-CS-Illl-d-Sw- |24 S43 |25-S22-l20-S42-l22-S43-l23* lllll-BB-(SaSn-Sai-Sao--Lzl Finally,l if the third available selection switch, namely, S34 is actuated, still the same carrier 35 will be advanced a notch, its latch-release solenoid 534 response to actuation of any one of the threeV selection switches San to S34. 'I'lius when a pur'-l -chaser actuates the selection switch Saz and drops .the selection switch S34 also causes thisame.

solenoid 53 to be energized (through a circuit Li |35 CS- |01--53-S24|28-S44|29f Sn'- y|24Sizi--IZS--Sz-i--I20-S4n--I22--S4e |25-Sg4--I21-lM-31 (Sai) -Sn--Saz--Sw-v Sao-La). When the contents of the third and last carrier 35 is exhausted it shifts its carrier switch S24 and oi course thereafter the lockout coil LC remains energized whenever any one of the three selection switches Saa-S34 for the beverage C is actuated so that the inserted coin is returned to the prospective purchaser,

. S50-S58 as well as the refill switch So.

In the example of load distribution described above, namely, that in which three of the car- 'riers are loaded with beverage C, ythe description has been conilned tothe operation of these three carriers. It will be understood, however, that the operation for the other carriers to dispense beverase A, B, D and E from them is, of course, the same as that previously described in the rst example of loading for the machine and in which a different beverage was placed on each carrier.

Any desired number of carriers can be loaded with a particular brand of best seller drink and set up for the interdependent type of dispensing operation described above. In such instance the multiplicity of carriers stocked with the same beverage should follow each other in the series, rather than being interspersed throughout the machine, and furthermore the combination switch if assumed that it was desired to dispense-the entire capacity of the machine. In many instances,

however, less than that number of bottles may be available for rlllingthe machine, or vperhaps some of them will not have been in the machine long enough to Vreach the proper temperature. To meetsuch contingencies provision has been made for cutting oit of operation not only desired ones of the carriers, but also for-limiting the number of bottles that can be dispensed from any one,

. of the carriers. To cut out a carrier itis simply for the first 'one of the special group of carriers should be put in its left hand position as shown and the others shifted to the right hand positions as was done with the combination switches S4: and S44 in the example explained in detail above.

Restocking the machine In replenishing the stock of bottles within the y machine the cabinet doors I I, I2 are swung open,

thereby automatically disabling the delivery dogs 81 as previously described (see Fig. 2). opening of the cabinet makes available to the operator the set of latch-release switches These switches can be manipulated to cause the drive motor 53 to revolve any or all of thecarriers 32 to 38 freely and continuously for purposes of reloading, as distinguished from notching them around step by step as is the case in dispensing. For example if the proprietor wishes to revolve the carrier 32" during reloading, he closes the latch-release switch S50 as well as the refill switch Se. Thereupon the latch-release solenoid This- 63'i is continuously energized (through a circuit- Li-I06-Se--I01-63L-I08-I30-S5o--I3 I-L2)- and the drive motor 53 is continuously energized (through a circuit Li-sm-I I I-ss-I Iz-Li), the motor switch Sio being closed to complete the latter circuit upon withdrawal of the latch from engagement with the carrier 32. It will be observed that the circuit traced just above for the solenoid 63 does not include the associated carrier switch Sao sothat the carrier can be freely revolved around and around past its stop position without this motion being interrupted by the actuation of the carrierswitch S20.' In the same manner any or all of the other carriers 33 to 38 can be freely 'revolved simply by closing the rfill switch Se and the corresponding ones of th latch-release switches S51 to Sse. Loading the bottles onto the carriers is a very simple matter in view of the construction of the latter. In loading a bottle onto the carrier the operatorsimply thrusts it, neck foremost, upwardly into the desired carrier pocket through the lower end of the latter: The nose of the bottle is entered beneath the detent iinger (see necessary to rotate it, during loading, to its "stop" position and in which its carrier switch (Sno' to Sn) is actuated by the stop pin on the carrier. As was previously described such actuation of the carrier switch disables the corresponding carrier against rotation during the subsequent dispensing operation of the machine.' In the same manner, if the operator wishes to deliver, say, only six bottles from carrier 32, he prelimlnarily positions it only six steps away-froml its stop position.V Then when its turn comes vto rotate -during the` dispensing operation it will be indexed only through these six steps and then` the shifting of its carrier switch S20 will disable it against further movement. Hence any other bottles that may be on the carrier 32 will be withheld from sale .and retained in the refrigerating zone. To accommodate additional preliminary storage of bottles, shelves |40 (Figs. 3 and 4) have been provided in cabinet compartment I3 in the clearance space at the side of the unit I4.

Safeguards forunattended machine tor shaft 49 continues to turn, with slippage in A the mating frictional surfaces of the drive connection, sono harm is done. of the carriers, with their initial half-step motion,y was previously described and by means of which unauthorized removal of a bottle through one of the delivery doors 25 is prevented.

t, .The control system is also so arranged as to prevent either an awkward or an uscrupulous 'person from obtaining two or more bottles for a single coin by retaining depressed a plurality lof the selection buttons I5 to 2l simultaneously when he drops a coin in the coin box 22. \Cheat Fig. 6) at the lower end of the pocket and as the bottle is thrust up into the pocket it raises the detent nger to permit the bottle to move freely into the pocket. After the bottle has passed the detent ringer the latter is snapped back downing o f the machine in the manner -noted is prevented by the simple electric interconnections be tween the selection switches S30 to S36. Upon reference to Fig. 12 it will be observed that each of these selection switches has a normally closed back contact to 96, respectively. These back contacts yserve to connect the switches in cascade or series so that for any one of them to be eiective to connect its normally open or forward contact to the source of power (i. e., to supply line La) all of the other switches between it and the source of power must be in their normal or unactuated positions. A review of the operations described above will reveal, however, that only by connection of its forward contact to the source of power-does the selection switch become enectiveinthe control circuit. Speciilcally, actuation agg' 'Ihe arrangement of selection switch Sai is eective only when theV switch ahead of it, namely, switch Sac is innormal position as shown, for otherwise its movable contact- 34 is disconnected from the supply line La and simply dead-ended. In the same way Sm is only effective when Sao and S31 are both in normal position, and so on, down the line.

f Bearing in mind the interconnection of the selection switches Sao to Sas described above, it will be apparent that if a purchaser actuates, say, both switches Sao and S31 when he drops his coin, only .the switch Sao will be effective to unlatch its associated carrier 32. Theother switch S31 does nothing. Consequently, he will receive one bottle from carrier 32 and that is all. In
