Claims. (01. 312-35) This invention, as indicated, relates to a vend- 'ing' apparatus. More particularly it comprises an improved type of storage, display and delivery apparatus for vending various articles of merchandise of respectively different sizes and shapes and is adapted for operation by a coin-controlled unit, and by an article selector unit which may be ofthe type herein shown, or ofv other type of construction, such, for example, as is set forth in myco-pending patent application, Serial No. 329,514, filed December 31, 1928, which matured into U. S. Patent No. 2,008,735, on July 23, 1935.

The principal object of the present invention.

' is to provide standardized units adapted .to be assembled in cooperative relation with aslittle duplication of operative elements, as possible, as

an apparatus for vending articles, which units may be combined selectively to accommodate articles of various size and shape, and also-be 20. adapted to handle fragile merchandise.

The units may be so constructed that they may be assembled in groups containing storage and delivery compartments for selected sires and shapes of articles and arranged for operation by g 25 means of one or more coin controlled units, and

a article selector units. Some of the operating elements are common to the entire apparatus, other elements are designed to serve one vertical group of units, and other elements are restricted to the so: individual units.

The apparatus is also adaptable to vending articles requiring refrigeration through the provision of cooling coils suitably placed adjacent to the storage and delivery compartments.

36. The apparatus thus. may be sectional in form and may be built up of selected units to accommodate any desired line or lines of merchandise with a minimum of expense for control apparatus and service requirements and permitting at all 40 times easy replacement, substitution or repair.

is a vertical sectional view of the selector and coin control units; and Fig. 10 is a rear elevation of 10 the apparatus shown in Fig. 9, together with the electric circuits to the operative elements.

The coin control and selector units and the electrical connections of the same, as stated, may be of the type shown in my co-pending applil5 cation Serial No. 329,514, (now U. S. Patent No. 2,008,735) but it is to be understood that still other forms of coin-controlled mechanism may be used instead, and that where very heavy or bulky articles are to be vended, auxiliary relays may be used in the circuit to control the motor and the delivery magnet.

As is clearly shown in Fig. l of the drawings, the apparatus comprises a cabinet i having groups of storage and delivery units 2 arranged vertically in one or more rows and having a selector 'unit 3 and a coin-control unit 5, adjacent one side for controlling the operation of the mechanism.v The details of the selector'unit and coin-control unit will be presently described after t0- the article storage and delivery mechanism are first set forth.

Each vertical group of storage and delivery units may have the individual members thereof formed of identically shaped operating parts,

. although the sizes thereof may be varied to accommodate diiferent sizes of articles.

In the present invention the apparatus includes dispensing units, each having a number of article storage and delivery compartments I associ'ateddil in the form of an endless conveyor or chain I. These compartments are preferably formed of sheet metal, or the like, with elliptical top and bottom members 1, 8, and a curved back wall 9.

The compartments are open at the outer sides and the elliptical top and bottom members are formed with projecting end portions Ii, i1. Connecting pins I3 are provided to be engaged through suitable apertures formed through the projecting end portions of such sheet metal comiii) partments. ,The pins are formed adjacent their lower ends with collars ll which seat'upon the respective bottom compartment walls, and posi- 'tion the pin so as to project above and below the overlapping portions of the sheet metal sections i in order that they may engage notches l5 in the supporting wheels or spools of the conveyor system. These wheels are preferably circular metal discs 46, ll united in spaced relation by a cylindrical hub member l8 freely supported upon front and rearward shafts'2l, 22, respectively extending vertically through the apparatus so that the wheels of the several superposed compartments are all pivotally mounted on a single supporting member.

The articles to be vended are placed within the compartments of the conveyor and are advmced step-by-step about the supporting wheels so that a purchaser may, through the coin and selector mechanism, cause any article appearing behind a. display window 23 at the front of the cabinet to be delivered to him by suitably operating the control mechanism and depositing. the necessary coins.

Each compartment may have a refrigerating coil 24 running through the same so that the articles to be dispensed may comprise other than the usual staples and package goods, and may include bottled beverages or packages of ice cream or any other articles which it is desired to supply in cooled or frozen condition. The margins of the discs of the respective wheels are provided with notches i5 within which the ends of the pins interlocking the compartments engage and provide the means for supporting and moving the entire chain of compartments with their contents.

The forward vertical shaft 2| upon which the forward conveyor wheels are mounted is an idling shaft or pivot rod and supports the wheels by means of suitable collars 26 secured in spaced relation onsaid shaft and engaging the lower side of each bottom disc, respectively, adjlacent its hub member. Bearings or supports 21 for said shaft are provided in the top and bottom walls of the cabinet. The rearward shaft 22 is the operating shaft and is adapted to be connected selectively with any one of the chains of compartments in its vertical series. It is adapted to be oscillated by means of a mechanism presently to be described. The rearward shaft extends freely through the supporting wheels, and also carries collars 28 secured in spaced relation on said shaft engaged therewith beneath said respective wheels. Each collar 28 has secured thereto an operating arm 29 which is substantially of Y-shape, with arms 3| thereof engagingon eitherside of the collar 28 and being pivoted thereto by means of pivot pins 30. A

supporting arm 32 fixed to the collar beneath said operating arm serves to maintain the same in a substantially horizontal position and in a plane slightly below the lugs 33 formed on the under side of each lower disc of the rearward compartment supporting wheel at spaced points adequate to shift such wheels and move the conveyor system the distance of one compartment length. ,The margins of the lower rearward discs are provided at suitable intervals with notches 36 which are shown as being intermediate the notches which receive the pins of the compartment chain. A locking arm 35 is piv-. otally mounted on a support 36 at the side of the wheel and having an angular lug 31 at its forward end is adapted to engage successively into the notches 34 of the disc as it is moved in the course of the operation of the apparatus. A

suitably operated.

cabinet.

The releasing and compartment chain actuating device will now be described. It comprises an electro-magnet 4| suitably supported by a frame member 42 attached to the walls of the ature 43 is provided, said armature having a weight 44 to prevent chattering when alternating current is used, and also to automatically restore the armature to normal position, and said armature carrying at its forward end a downwardly inclinedguide member 45. This guide member is adapted to be rocked downwardly when the opposite end of the armature is attracted upwardly. Thesloping upper surface of the guide member 55 of the armature is thus low- 5 ered into the path of the delivery arm which, when carried through its outward range of motion by the oscillation of the shaft 22, rides over the inclinedtop face of said guide member and is raised through contact with its sloping surface so that it engages against the locking lug 37 and disengages it from the notch 34 in the disc. .As the arm moves further it comes into contact with one of the lugs 33 on the under side of the bottom disc and moves said disc the distance of one compartment. 3 Thus the compartment originally in back of the display 'window will be moved to a position back of the opening 45 through which the article may be obtained by the customer. In the meantime the electric contact will be broken, as will be hereinafter more particularly described, and the armature will rise and the operating arm will be dropped to a horizontal position. The locking arm then enters the next adjacent notch on the lower rear disc when it is brought into registry, thus locking the chain of compartments and placing the article in the succeeding compartment back of the display window.

The chain of compartments carries on one of-the compartments 9. projecting lug 41 which is adapted to contact with a spring 48 carrying a contact 49 forming part of the control circuit, so that when the last article in the chain of compartments has been dispensed, the circuit will be broken, and the further deposit of coins will result in the operation of a refunding mechanism, which mechanism may be of the type setiorth in my co-pending application (now U. 8. Patent No. 2,008,735). 50 The operative mechanism as associated with the selector and coin control apparatus is best shown in Figs. 7, 8, 9 and 10 of the drawings. As heretofore stated, the rearward shafts 22 ex-' tend respectively through the rearward sup- 5 porting wheels of each vertical row of conveyor chains of each vertical series. At their lower ends they areprovided with operating arms 5| connected by links 52 with delivery arms 53 on the universal operating shaft 54 extending horizontally across the rear portion of the cabinet and journaled in bearings 55 formed in supporting arms 56 secured to the frame work of the cabinet. The operating shaft carries an operating arm 51 adjacent one end which is engaged by the lower end of the release rod 53. The release rod at its upper end, is mounted on a pivot pin 61 on the drive disc 82, which is car- 1 ried on the worm wheel shaft 63. The worm wheel 64 of said shaft is adapted to be driven by a worm 65 onthe shaft 66 of an electric motor 61. A beveled gear 68 is also mounted on the worm wheel shaft and through mechanism herev inafter to be described operates the coin-releasing mechanism.

Beneath the electro-magnet an arma- The wheel carries a control pin II for a maintaining switch I! of the electric circuit which will be hereinafter described in connection with the circuit connections.

brush I9 connected with the conductor element of the circuit. The contact finger is adapted to be moved over a plurality of stationary contacts i, each connected with one of the electromagnets 4| positioned respectively adjacent the rearward wheels of the respective conveyor chains.

Beneath the selector mechanism 3 the coin control mechanism 4 is positioned. This mechanism comprises coin chutes 03, 84, shown as two in number and for two diilerent coin sizes. However, it is not intended to limit the mechanism to any specified number or sizes of coinsand a mechanism may be used for this apparatus corresponding to that set forth in my co-pending application (now U. 8. Patent No. 2,008,735) heretofore referred to, wherein one or more coins forming different price combinations may be employed and also refunded in the event of a mistake by the applicant or the exhaustion of any indicated line of merchandise.

The coin chutesare provided with suitable coin slots, 08, or openings on the front panel of the apparatus andterminate in a coin box 91 within the apparatus. At an intermediate point each coin channel is cut away on opposite side edges to provide an opening 80 on each outer edge 'for an insulated switch-actuating lug 90 and an opening 89 on the adjacent inner edges for the plates of the coin arrester and release mechanism, which comprises inclined plate members 92 supported on an arm 99 attached to a rocking bar 94 and normally held by a spring 95 in a position to i'oreethearrester plates inwardly against the front walls of the coin chutes. The rocking bar carries an extension arm 95 at one end having; a projection 91 in a position to be acted on by apin 90 carried on the under side of a rotating disc 99 mounted on a shaft IOI suitably supported on brackets I02 adjacent said extension arm and having a beveled gear I03 at its lower end engaged with beveled gear 90 on the worm wheel shaft 09 heretofore described.

. As stated, the switch-actuating lug normally projects into the coin channel, said lugs being carried on movable switch arms I04 of a pair of switches I05 connected in series with a relay I00- shown at the bottom of Fig. 10, and when said "switches are closed, the relay will be energized to noting the number of the window of the article return line I22. The star he desires to purchase and then turns the se-v lector knob IS-until the desired numberappears at the indicator window 10. He then deposits 8. coin of the indicated denomination in each of the slots 85, 86, of the coin chute. The coins move 5 down the coin chutes until they engage the inchned plates 92 of the coin arrester and release mechanism which causes them to engage respectively the insulated lugs 90 of the series switches I05 and hold such switches closed until the coins are released as will behereinafter ex-' plained. In this manner a circuit will be closed through the conductor III attached to one branch H5 of the main line from the power source, through the windings of the relay I06 the conductor H3 and series switches I05 and through the return line II4 to the other branch II2 cf the mainline. The relay I06 when thus energized will attract the armature IIS and the depending arm III thereof will coact with the insulated lugs H0, 9 to move the flexible switch arms of the switches I01, I08, respectively into contact withtheir companion switch elements. V

The closing of the switch I01 will energize the motor 61 through the conductor HI and the ting of the motor will move the control pin II away from the flexible arm of the maintaining switch I2 and will permit the latter to close. The current through the motor will then be maintained through said switch until the motor has moved the driving disc 62 through one complete revolution and reopened the maintaining switch'by again bringing the control pin II against the switch arm.

The driving disc through the release rod 00 and the associated shafts and links of the article delivery .mechanism heretofore described moves all of the operating arms 29 through one complete oscillation. All of the arms move idly adjacent 40 the respective compartment chains excepting the arm adjacent the compartment carrying the selected article, and this arm is moved to an elevated operative position as has been heretofore explained and serves to move the selected compartment chain, one compartment length.

The closing of the switch I00 by the relay I00 closes the circuit through the conductor I23, brush I9. ring 18. contact finger I1, and through the -selected contact terminal 0| through the winding of one of the electro-magnets 4I and return line H4. The selected 'electro-magnet 4I attracts its armature 43 which brings the sloping guide member 45 into the path of oscillation of the adjacent operating arm 29 and moves the compartment chain thus selected in the manner heretofore described.

Before the electro-magnet circuit is broken, the inclined guide member 45'under the selected magnet M will have been lowered and will raise the operating arm" associated with the selected conveyor chain into contact with the locking arm 95 of such chain to release the same and then will drop the operating arm onto a supporting flange of one of the depending lugs'fl on the selected conveyor chain disc. When the relay is de-energized the inclined guide member rises out of the path of return movement of the operating arm which immediately after leaving a position w in contact with a supporting flange on the depending lug falls to a horizontal position and thereafter clears the succeeding depending lugs on the conveyor chain disc and will not again contact therewith the particular electromagnet of such conveyor chain is energized in due course of operation of the apparatus.

At -each action of the device the selected conveyor chain will move one compartment length and when the chain has completed its circuit and all the compartments are empty, the lug i! on one of the compartment discs will contact with I the switch arm 48 mounted at the side of the frame work in the path of such lug and will open the circuit to prevent operation of that conveyor chain by means of mechanism corresponding in detail to that set forth in my co-pending appllcation (now U. S. Patent No. 2,908,735) heretofore mentioned.

The series switches flit will he maintained in contact until the coins are released into the coin icon "at. The release of the coins is brought about by the withdrawal rearwardly of the coin arrester and release mechanism. This is accomplished by the rotation of the iiii through the bevel gears Q39 and ifiit and the bringing of the pin tit? on the disc into contact with the projection i'i on the arm of the rocking bar whereby the rocking bar 98 is oscillated. The lower end of the supporting arm it carrying the inclined plate members 92 is moved rearwardly and the plates are thus withdrawn from the com chutes and permit the coins to fall by gravity into the coin box.

The filling of the compartments of the con-- veyor chain may take place through the dispenslng window 16 or through a door ill! at the rear of the apparatus. The locking lug of any conveyor chain may be withdrawn and held retracted while the filling operation is taking place or suitable means may be supplied for simultaneously withdrawing all the locking lugs at one time so that the compartment chains may be freely rotated and any vacant compartments filled without separate unlocking.

. As has been heretofore stated, the various features shown in my co-pendlng application, since issued as U. S. Patent No. 2,008,735, may be combined with the features of construction herein disclosed. Thus the selection of diflierent coin values as well as dlfierent articles by the selector may be arranged for, and the refunding of the coins under certain conditions may also be provided for as well as many other structural features set forth in said co-pending application, since issued as U. S. Patent No. 2,008,735
