Application filed October 6, 1925. Serial No. 60,822.

The invention relates to a vending machine and relates more particularly to com control vending machines of the non-selective type wherein the articles are contained 5 in a plurality of compartments which are successively and progressively advanced to alignment or registry with a delivery opening, each progressive movement oi-the compartments being permitted and controlled by the insertion ofa coin ina collection receptacle, thereby permitting the operating handle to be actuated. i 4

An important object ofthe invention is to provide a coin control vending machine Oil the character described comprising a rotary drum having a plurality of radially disposed pockets adjacent its periphery, said pockets being in alignment with corresponding windows in the drum casing for the inspection,

of prospective purchasers, said drum being actuated by a centrally disposed handle to progressively bring saidradial compartments intoregistry with a single dispensing door aperture in the drum casing.

*vide a vending machine of the character described so constituted as to cooperate with a coin control mechanism to permit the dis pensing door to be opened only after thein-" sertion of thepropercoin. v I a A further object of the invention is to provide a machine of the character described which is incapable of actuation except upon the insertion of the proper coin together with means for automatically returning lDOjtllG purchaser any undesired coin ofany size-capable of being inserted in the reception slot provided for the purpose.

A further and important object isto provide a vending machineconstituting a rotary drum having radial article receiving compartments adapted to be moved progressively into registration with anormally closed door, the opening and closing of said door heing controlled by suitable mechanism in turn controlled by the operating handle tomove A further object of the invention is to pro-- operation of opening and closing said door.

The insertion ofthe coin releases the lock-o ing mechanism temporarily to permit the a drum to be advanced one step by theoperat 0 ing handle to bring a filled compartment into registration with the dooropening, said door being automatically opened immediately thereafter by the continued movement of the operating handle, to permit access by the purchaser to the contents of the compart ment. f l

A further. object of the inventions isto provide a machine of the character described a in whichsuitable mechanism is provided to 7 lock the drum and the coin control mechae nism against further actuation after all of the contents of the radially disposed c0111- partments have been sold, together with automatic means for visibly informing subse- 7 quent purchasers thatthe machine has been emptied ofits contents. i

A further object of the invention ism rovide a machine of the character described fwhich may be economically manufactured 8U andassembled, with most of the working parts die-pressed, said parts being capable of beingvassembled rapidly and providing a machine which isextremely durable in its nature, as well as adequately protected against pillage by unscrupulous and unau- 'thorized persons.

'Referring to the drawings, the machine comprises a circular standard or frame 1 having legs 2 which may be suitably secured as at 8 to a table, wall or counter, said frame having a hub portion 4 and radiating legs or braces 5. The hub 4 is provided with a hollow horizontally projecting stud shaft 6 adapted to support externally a corresponding central hollowv spindle or shaft 7 of a rotatable drum 8. The drum 8 is composed of a rear wall 9 centrally apertured to receive the stud shaft 6, a front wall 10 and a plurality of radially disposed, preferably uniform pockets or compartments 11, the walls of the latter being secured in any desired manner to the circular walls of the drum. As illustrated the walls of the radial compartments are shown as provided with integral lugs 12 adapted to be inserted in suitable slits in the circular walls of the drum 8 and thereafter clinched against said walls.

The drum element 8 further includes a gear wheel 13 rigidly secured by screws or bolts 14 to a triangular casting 15, the latter being secured by said screws or bolts to said drum and constituting a support for the central hollow stud shaft 7 adapted to rotatably and externally engage the shaft 6 of the frame or standard 1; The triangular frame member 15 is further provided with a radially eX tending arm16 having a locking projection 17 thereon for the purpose of locking the drum when emptied in a mannerwhich will be hereinafter described.

The drum 8 is rotatably supported on the standard 1 by means of the cooperating hollow shafts 6 and 7, and the drum is mainin thedrum, said'part 18 thus enclosing the drum more or less completely. A plurality of lugs 21 of any desired number are suitably secured on the circumferential orannular part of the casing'lS which lugs are designed to cooperate with and engage behind corresponding lugs or wedges 22 on the circular standard or-frame 1. The casing 18 is assembled by moving the lugs or ears 21 and 22 into transverse alignment and then engaging the same by aslight rotary movement of the casing to theright to frictionally engage the lugs. The latter may be perforated as indicated for the reception of one or more 'padlocks 23 by means of which the machine is locked in its assembled position.

Thefront casing member 18-hasintegrally formed therewith or secured thereto a coin control housing 24 havinga coi-n reception slot- 25, (Fig. Suitable coin control mechanism is contained within the housing2et-which cooperates with the mechanism of themachinc to actuate the latter only when the proper coin has. been inserted. The coin control mechanism ismounted on and actuated by the shaft 19 ro'ectin at its forward end P l a through a hub portion 25 and having an operating handle 27 keyed orotherwise rigidly secured tothe forward end of said shaft. The particular construction of the coin control mechanism within the housing 24 forms no part of the-present inventionand therefore will not be further described indetail. It is sutiicie-nt to state that this mechanism is operated byithe manipulation of the handle 27 and that the coin must be first inserted in the slot 25 provided for the purpose. Any improper coin of a denomination to per; it thesame to be inserted within the slot 25 fa ils to pass through the coin control elements and is returned to the customer through a circular recess 28 (Fig 1) communicahly connected with the coin slot 25.

The casing 18 is further provided with an integrally formed sliding door housing 29 having an aperture 30 therein which is normally obstructed by the door when the latter is in closed position. The casing 18is further provided with a plurality of window apertures 31 which may correspond insize, number andlocation with the radialcome partments 11 of the drum 8 orinay be proportionate in number thereto, so that the contents of said compartments are visible through the window apertures ofthe casing when the machineis assembled. The window apertures 31 have disposed therebetween radially extending ribs 32'preferably integrally cast with the casing 18'. The ribs are designed to haveseatedtherebetwcen a preferably having a covering of yieldable' packing to minimize the danger of breaking the glass when being assembledor during the operation of the machine. The ring section or sections 3% is or aremaintained in p ositio-n against the radially innermost edg i: of the glass sections on the innerface of casing 18 by means of a plurality ofsprnig plates 35 yieldably pressed inengagement against thering gliby means of suitable screws or otherfastening devices threaded into the projections 36,the latter being pref? erabiy integrally formed with the casing-18 (Fig. 12).

The sliding door or shutter is preferably 1 constructed of ametallie rim or frame 8? having a plurality of lugsBS adapted to maintain a glass section assembled in position within said door frame, (Fig. 3). The door frame 37 which may correspond sub stantially in dimensions to one ofthe window sections,terminates'in a depending portion 39 pivoted at lOto a main door operating lever 41, the latter suitably pivot-ally sup ported as at 42 to the inner side of the easing 18. :The depending/portion 39 of the door frame is further provided adjacent its lower end with a pinor projection 4 3 having a limited lateral movement within a slot latformed in the upper end of the main door operating lever 41. The construction described permits limited swinging movement of the door frame 37 relative to'its operating lever ll to permit a certain amount of cushioning action of thedoor during the slidin movement thereof within its housing thereby minimizing possibledamage to the door structure. This described arrangement further permits the door to be swung. radially from opento closed position and vice verse is closed and n the slot 25. The knob 27 and shaft-19 are from the pivot 420i themain operatinglever The main door operating lever 41 is i also. preferably provided adjacent andfbelow the depending portion 39, with a. pin or pro-- jection 45; adapted to engage a depending bi furcated portion of the slide member 45 con trolling the coin slot. By this simple arrangement the slot is maintained closed to obstruct the passage therethrough of a coin when the door is open the movement of said -lide permitting the insertion of a coinwhen the door is swung to closed position.

The opening and closing of the door, the coin control, as well as the various mechanisms for eriodically locking and releasing the rotary drum 8 at the proper intervals, is

con-trolledbythe central shaft 19 passing through and'having suitable bearings inthe coin control housing 24L, said shaftbeing roi'uatablygournalled at its inner end withinthe hollow central shaft 6 of theframe or stand ard 1. The several mechanisms described may be controlled and actuated by turning the operating lznob or handle 27,, fixed on the shaft 19 and the mechanism is such that the drum 8 may be actuated only when the door after a coin has been? inserted turned to the right to rotate the drum 8 one step to the left, and substantially simultaneously therewith the sliding door37 is opened by the continued movement of the operating handle toperniit access by the purchaser to the filled compartment which has been moved into registration with the door opening.

Lhemechanismis further of such character that the drum 8 1S securely locked in posi-' tion at alltimes, whether the door is open or closed, except for the brief nterval when it is being advanced one step by the operatin handie at which interval the door is in the act of opening. 7 The mechanism is further of such character that the door 15 closed by a reverse movement of th'e'operating handle orto the left, to render the coin slot free for n the reception or a succeeding coin and to reice set the controlling mechanism for a subsequent partial rotation of the drum to advance the succeeding filled compartment into registration withthe door opening. 'The mechanisin is further of such character that the door is alternately opened and; closed rapidly with a minimum of effort on the part of the operator. until the machine has been emptied of its contents. a

The shaft 19 carries on its intermediate portion. within the coin housing 24a loosely mounted disk member 46 having; a hub. or-

tionfl'?onthe'inner side thereof, said hub' poi n being preferably cut-away'asillus .trater, to provide diametrically opposed notches or recesses 48 and apair of interposed projections ll). "The disk nieinber46 is furj thcr provided adjacentth-e periphery thereof with P21113701? diametrically opposedspins or corresponding rollers 51, 51.

projections 50, to provide journals for The shaft 19 is further provided with a transverse elongated rod 52passing through a suitable aperture in said shaft, and the purpose of which rod is to actuate the mechanism for closing the door as will be hereinafter described.

Each of the rollers 50 and 51 are designed to contact with the cam surface 53 on the main door operating lever 11 to move the latter and the door to open position on the rotation of the operating handle. Said rollers are also designed to contact with a corresponding cam surface 54 of a lever 55, pivotally mounted at 56 to the lever 41 and normally held by a spring 57 against a stop or lug 58 on the lever 41 to maintain the end of the locking lever in engagement with a projection 59 preferably integrally cast with or formed on the casing 18, thereby normally preventing the door 37 from being opened. The main door operating lever d1 has pivoted thereon as at 60 a rocking lever 61 having an upper projection thereon, which projection when the door is closed and partially open is normally held by gravity and by the tension of a coil spring 63, pivoted to the opposite end 64: of said lever, in engagement with an inwardly projecting stationary shelf or bar 65 suitably secured at 65 and 72 to the casing 18. The bar 65 is further pro vided on one edge thereof with a cut-away portion or recess 66 and an upstanding projection 67 for a. purpose to be described. The projection 62 of the lever 61 is adapted to engage the cut-away portion 66 when the door is being 'opened thereby permitting said lever to drop, assisted by the spring 63 and this movement serves to engage a second lug or pro ection 68 thereof with the peripheral teeth 69 of the gear wheel 13, rigidly secured wheel.

to the outer wall of the drum 8, to lock the drum. This engagementis preparatory to moving the drum the requiredmlistance to present a filled compartment thereof in registration with the door opening of the casing, on the continued movement of the operating handleQ Prior to the locking engagement of the projection 68 with the gear wheel 13, the drum is locked in position by a lug or projection 70 on the lower end of one arm 71 of a bifurcated lever pivotally mounted at 72 to the casing 18. The projection 70 normally engages the peripheral teeth 69 of the gear lVhen the projection 68 of the lever 61 drops down to lock the drum preparatory to moving the same as above described, said projection contacts with a. second arm 7 3 of the bifurcated lever, thereby moving the latter and its projection 70 out of engagement with the gear wheel and against the tension of a coil spring 74 secured at one end to the arm '71 and secured at its other end as at 75 to a suitable projection on the casing 18.

The action ofthe spring74 is to normally maintain. arm 71 of the bifurcated lever against a suitable stop 76 on the casing and the projection 70 of said lever in looking engagement with the gear wheel 13 of the drum. A spacing block 77 may be provided between the arm 71 of the bifuroatedlever and the casing 18 to insure the desired rocking movement of the lever into and out of locking engagement with the gear wheel teeth.

After the projection 68 has dropped into engagement with the gear teeth and projection 70 has by the same described movement become disengaged from said gear teeth, the continued rotation of the operating'handle completes the movement of opening: the door, by reason of the continued engagement of the roller 51 with the cam surface 53 of the pivoted main door lever 41 and this described movement results in the drum 8 being ro tooth yieldingly maintained in engagement with the peripheralteeth of the gear wheel- 13 by means of the coil spring 57, to permit rotation of the drum in one direction only,',or in a clockwise direction as viewed inFig. 3. The pawl 79 is limited in its normal tendency to be drawn toward the teeth of the gear wheel 13 by means of its tail 80 contacting with one of the projections 36 on the inner face of the casing 18. A fixed stop is thereby provided for the spring 57 for its cooperation with the door locking lever 55.

The door is closed as described by reverse rotation of the operating handle which for each successive closing movement, engages succeeding ends ofthe rod 52 with a projection 81 of a suitably weighted lever 82 piw oted at 83 to the casing 18.- The continued reverse movement of the operating handle raises the lever 82 overcoming its weighted portion andbringing a second projection 84' thereof into engagement withthe lower edge of a lever 85 pivoted at 86 to the casing and having an upturned portion 87 disposed in the path of the pro ection 68' of the rocking lever 61 when the door is in open position.

The door 3? is normally locked-in open posi-' tion by the engagement of the shouldered end 88 of a locking lever 89 with a suitable projection 90 on the main lever 41. The lever 09. is also pivotally secured to the casing by means of the pivot 86 and is further provided with an upstanding tail portion 91 to which is secured one end of the spring 63. Thelatter therefore becomes in effect a floating spring. The locking lever 89 is further provided with a cut-away portion or recess 92 disposed in the path of the'projection 84 of the weighted lever 82 so that the locking lethe projection 68 and lever 61 above the bar 65 preparatory to being returned spring 6. 5 intoits normal position with projection68 resting on said bar when the door is in closed position. It will be apparent that the door is closed by the tension of spring 63 after locking lever 89 has been lifted from engagement with projection 90 on main door operating lever 41. V

In the operation of the vending machine and assuming the sliding door37 to be in closed position, a coin is inserted in the slot of the coin control housing 24; and the operating knob or handle 27 is turned to the right or in a clockwise direction as viewed in Fig. 1. The operating handle is keyed to the central shaft 19 and this rotary movement thereof to the left or in av counter clockwise direction as viewed inFig. 3.

I trade the coin control mechanism to v A cam member 92 is rigidly connected to or constructed integrally with the mounted disk member as and serves to ac coin from the slot into its collection recep tacle when the shaft 19 is rotated. The shaft gage its extremity from the locking projeo tion 59 on the casing. This releases the normally locked lever ll and permits the sliding door 37 on the upper end thereof to beopened by further rotation of the shaft 19. i The continued movement of the handle brings the roller 51 into engagement with the curved cam surface 58 ofthe main door operating lever 41 and swings the latter outwardly on its pivot 42 against the tension of the coil spring 63 and to the right as viewed in 3. As the main pivoted lever ll moves to the right against'the tension of the spring 63, this spring tension also tends to swing downwardly the free end of the pivoted lever 61,

p but the latter is prevented from dropping downwi-trdly by the engagement of the projection 62 with the horizontally disposed bar 65. The latter is cut away as describedat substantially its middle portion 66 to provide clearance for the lug 62 after the latter has traveled to this point on the bar 65. There after during the continued rotary movement of the operating handle the lever 61 ispermitted to drop downwardly when thelug 62 p v reaches the recess 66 and the lower portion 68 of the free end of said lever engages the end loosely carry the lower pro against the arm 73 of thelever I .73 of the bifurcatedlever 711to movezthe latter out of locking engagement with-the gear wheel 13"and simultaneously engage thelug 68 with the teeth of said gear wheel; 7 I

The drum 8 carrying the articles to be dispensed in its several radial compartments, is

now free to be rotated by lug 68 on the continued movement of the operating handle,

to move a filled compartmentintov registry with the door opening covered by sliding door 37: lt will be noted that the downward. movement of the lever. 61 to move the lever arm 71 out of lockingengagement with the gear 13 of the rotary drum occurs when the' sliding door 37 has been moved only partially open and, while the drum is freeto he -rotated by a continued'movement of theoperating handle at the time it is unlocked, an empty "compartment is still in registry with-the par tiallyopen doc-in, It might be further stated that in this position ofthe mechanism the coin has been carried around within the coin I control housing out'of alignment with the slot" 25 in which it was inserted. It will; be furi ther noted that in theodescribed positionof the elements, the door is prevented from being closed h-y the' pull of the'spring 27.

by means of'a depending projection 1980f the sta'tionary'bar 65 now disclosed in the path of the lug 62 of the lever 61 when the 'ection 68 of the latter is resting The continued, rotation of he operating handle carries the roller 51 further along the curved cam surfaces 54 and 53 of the levers 55 and 41 thereby projecting the :main operating lever 41 further to the right. This produces a corresponding bodily movement in the same direction ofthe lever 65 carried by the lever ll. As the projection 68 of the lever 65 is now engaged between the peripheral teeth ofthe gear 13, this described movement tothe rightof the lever 41 partially rotates the drum 8 a "sufficient distance to bring a filled compartment thereof into reg istr with the sliding door 37 which by this same movement is now completely open for of said filled compartment; As above described the door is moved toopen positlonby the customer to obtain 'access to the contents the engagement of theroller 51 with the cam surface 53 of the pivoted lever 41. i

At this time when the roller 51 clearsfth cam surface 53 of the lever 41 said lever and the door carried thereby are locked in open position by'the shouldered end 88 of the lever 89 dro'pp'inginto engagement With the pro- ,jection'90 on the'le ver 41 and mainta ned in locking position by the tensionof the floating coil spring 68. The spring 63 exerts tension on the arm 91 which is preferably an integral upstandingportion of the pivoted lever 89. l

At substantially the time when the door has been moved completely open against the tension of the spring63 and looked as described in open position, the roller 51 clears jection 68 of the/lever 65 is still in engagement with the teeth of the gear wheel 13 of thedrum and the latter can therefore be rotated a succeeding step only after the door has been closed. The engagement of the notch 99 of the lever with the projection 59 looks the sliding door against further "movement in the direction of the rotary drum 8 while the door is open, and therefore it is only possible to remove the contents of the compartment which has been presented in registry with the door aperture during the operation of moving said door to open position.

In order to further insure the rotation of the drum carrier'in one direction only (in. a clockwise direction as viewed'in Fig. 1), the pawl 78; pivoted at 50 to the casing, is normally pressed into engagement with the peripheral teeth of the gear 13 by means of the coil spring 57 secured to said pawl. The tail 80 of the pawl is-normally engaged by said spring with the stop 36 on the casing to limit the movement of the pawl in one direction and to further insure a working engagement of the spring 57 with the pivoted lever 55. It will therefo-re be apparent that the pawl 78 permits the carrier drum to be rotated in one direction only and the engagement of its tooth with the gear 13 prevents reverse movement of the drum, which is of special utility when the machine has become partially. emptied of its contents while in use, resulting in the drum having a tendency for retrograde movement due to the weight of the articles carried thereby.

As heretofore stated in order to obtain access to the next succeeding compartment of the drum carrier it is first necessary to close thedoor 37, which action uncovers the slot 25 of the coin cont-ro l housing and places the coin reception mechanism in position to receiveanother coin. The door is'closed by the same or a. succeeding customer by reverse movement of the operating handle 27 or in in a counter-clockwise direction as viewed in opposite end of the rod 52 engages a projection 49 of the loosely mounted disk member 46. The subsequent.rotation'of the disk member in a reverse direction serves through connected spring actuated mechanism rotat- CESS- ing therewith onshaft- 10 to reset the coin control mechanism to receive a subsequent coin. At the time this reverse rotation is commenced one end of the rod 52 engages the projecting lug 81 of the rocking lever 82 pivoted at 83 to the casing. The continued rotation of the operating handle and shaft 19 in reverse direction raises the projection 8d of the rocking lever82 thereby successively raising the pivoted levers 85 and 89 respectively from their position at rest against the fixed stop 85 on the casing. The rearmost lever 89 as viewed in Fig. 3, is provided with a cut-away portion or recess adjacent the projection 8st of the lever 82, the presence of whichrecess permits the outer lever 85 to be first raised independently of lever 89 a dis tance corresponding to the depth of said re- This independent movement of lever 85 engages the upturned end 87 thereof with the'lower lug 68 of the pivoted lever 61 to move the latter upwardly against the tension offloating spring 63. This movement -permits tension spring 74 to again move locking projection 70 on arm 71 of lever pivoted at (2 into engagement with the teeth 69 of gear 13 to once more lock the drum 8 against rotation in either direction. The stop 76 serves as an auxiliary limit to inward movementof the arm 71. At tie time the drum is again locked by the projection 70 engaging the gear teeth, projection 84 of lever 82 engages the rear wall of recess 92 and thereafter pivoted levers 85 and 89 are moved upward simultaneously. The further function of lever 85 is to lift rocking lever 61 until projection 62 thereof passes through the cutaway portion 66 of stationary bar and is lifted above and clear of a downturned projection 66- (Figs. 8, 7 and 8) on said bar 65, and said projection 62 is therefore in position to be moved to. the left as viewed in Fig. 3 to again support lever, 61 in raised position by the engagement of projection 62 thereof with the bar 65. This desired and described re-eugagement ofprojection 62 with bar 65 is ofyfected'by the door being closed imi'nediately by. spring 63 upon the described lifting of lever61. This movement f the door to closed position permitted by lever bcing lifted by projection 84- on lever after said projection has reached the inner wall of the recess 92 on said lever. The upward movement of lever 89' releases the notched or cut-away portion 88, thereof from engagement with projection 90 on the main door operating lever 41, thereby permitting the latter and thedoor carried thcreby to be rapidly moved to the right (Fig. 7) to closed position by'the tension of coil spring 63. All of the elements of the mechanism are now in position to permit the door to be again opened and rotary drum 8 rotated another step, upon the insertion of a coin and through the rotation of the operating handle 27 to.

the right as viewed in Fig. 1 and to the left as viewed in Fig. 7, upon which occasion the various elements cooperate and perform their respective functions as has been hereinabove described.

T he function of the upstanding projection 67 on bar 65 is to positively engage lug 62 at the timethe latter. reachesthe'cut-away portion 66 of the bar when the door is being opened and to insure the lever (:31 dropping downwardly assisted by spring 63 to.

- cut-away portion 66, and the consequent failure of the lever 61 to drop down might capse the lower projection 68 of the'lever 61 to skip or fail to engage the proper tooth of the gear wheel 13, thereby'resulting in the failure of projection 68 to serve its further function of releasing gear wheel 18 through its engagement with arm 73 of lever 71 with probable jamming of the mechanism.

When all of the radial compartments 11 of the drum 8 have been emptied of their contents, the machine is designed to become automatically locked with the door in open position. lVhen the door is in open position the coin slot is obstructed by-the sliding shutter 45 controlled by the pin 45 on the lever d1, the position of said slide to obstruct or on pose the coin slot depending on the position of said lever. The drum filled with merchandise has been inserted in the casing in a predetermined position so that a definite compartment is first relieved of its contents, and the other compartments are subsequently emptied progressively and in succession. When the drum has been rotated to present the last compartment containing merchandise to bevended into registry with the door aperture, the locking projection 17 on the radially projection arm 16 mounted rigidly with the gear wheel 13 and drum, comes in contact with a corresponding projection 93 rigidly secured to the pivoted lever This engagement prevents the usual reverse movement of theoperating handle to lift levers 85 and 89 as'heretofore described'in order to, close the. door. Said lever 85 cannot be rocked upwardly by lever 82 because, of the contact of stop 98 thereof with projection 1'? carried by the drum. The drum cannot be rotated in the opposite direction, or forward", to release engagement of projections 17 and 93 by reason of the described engagement of locking projection 68 of lever 61 with the peripheral teeth of the gearwheel 13.

In this position of the machine, and as a further notice to the public 'that all of the contents have been sold, the last remaining filled receptacle is preferably providedwith a flap 94: (Fig. 4) preferably suitably hinged to the drum periphery and which is normally maintained pressed inwardly in unexposed position by the contact against it of the merchandise to be vended. When this merchandise is removed the hinged flap 94 drops down by gravity to the position shown in Fig. ltO display the word Empty or the like through the door aperture 30 to indicate 'to subsequent purchasers that the contents of the machine have been sold out.

'It is now necessary to restock the machine; which operation is effectedbyunlocking the padlock 23 and removing the casing from the drum thereby exposing all of the radial compartments to view. After the compartments have been filled with the merchandise to be sold the casing 18 is replaced but with the last compartment to be again emptied immediately to the right of the door opening as viewed in Figs. land 4, which act of positioning places the cooperating lugs or projections 17 and 93 in reverse position to permit a complete rotation of 860 degrees of the drum before said projectionsagain'come into locking engagement (Fig. l); It will be apparent that the replenishment of the drum with merchandise serves'too'nce more swing back to unexposed position the flap 9% bearing theword Empty or the like.

In order to insure the proper positioning of the cooperating lugs 17 and 93 to permita rotation of360 degrees of the drum, the easing 18 may be positioned over the filled drum with the aid of any suitable pointed implement which is inserted through an aperture 95 in the circular frame 1 (Fig. 2), and through a corresponding aperture 96 in the drum 8 which has been positioned upon the central spindle 6 carried by the frame 1. The

ment. 'VVhen the apertures 95 and 96 and:

notch 97' are aligned as described, the peripheral cars 21 on drum 18 occupy their proper position to the left or and in a plane within the circumferential plane occupied by the cooperating ears 22 on the frame 1. The positioning pin or implement is removed and a slight rotary movement of the casing to the right serves to securely engage the peripheral cooperating lugs 21 and 22 as illustrated in. Figs. 1 and 2, and the padlock 23 is attached through one pair of the cooperating lugs to securely lock the machine in assembled relation.

Thepre'sent application is designed to cover more particularly the improved and simplified mechanism for actuating a normally closed and locked vending machine of the til non-selective drum type, after the coin controlled mechanism is released by the insertion of the proper coin. Any desired and suitable form of coin controlled mechanism may be used in conjunction with the present improvements to permit the main operating shaft to be rotated by its operating handle.

For example, a coin control may be utilized such as is fully described in my co-pending aplication Serial No. 413%,? 70, filed iiipri l 27, 1921 for coin controlled device. An examination of the coin controlled mechanism described in my said co-pending application will aid in a complete understanding of the present machine and said other application is hereby made a part hereof so far as it is necessary to the understanding and operation of the invention herein claimed.
