WOODLAND E. GILBERT, F ST. PAUL, MINNESOTA.

VENDING MACHINE.

Application led pil 25, 1922. Serial N0. 556,380.

To all whom it 'ma/y concern:

Be it known that I, WOODLAND H. GIL- BERT, a citizen of the United States, resident of St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Vending Machines, of which the following is a specification. This invention relates to new and useful improvements in vending machines more particularlyl of the type which normally maintain a commodity within'a locked container and are adapted to be unlocked by a purchaser Without the necessary` intervention or attendance of the seller. he present commercial type of such machines is usually unlocked to permit removal of the commodity or operated to deliver it, by means of a coin, disk, or other token which usually is received Within and retained by 4the vending machine. Such machines are useful when operating as isolated units, or in batteries or series when an attendant is constantly and conveniently at hand to make change or sell the necessary token. An obvious disadvantage of the present coinoperated machines resides in the fact that purchasers running out of coins of the eX- act denomination needed frequently do not take the trouble to acquire an additional supply. Such disadvantage is aggravated when it is attempted to have the machines actuable by two or more coins of different denominations in order to charge a. fair price for the vendible commodity. Furthermore, in the case of tokens there is the danger of unauthorized duplication and consequent operation of the machines at a loss.

ln this novel invention, the vending ma-v chine is adapted to be operated by means of an instrumentality upon which the` charge for the contained commodity is marked when the machine is unlocked or opened to permit removal or delivery of the commodity. Such type of machine is particm `larly adapted for use in a series or battery where it is desired simultaneously to oiii'er for sale a plurality of different commodities at the same place such for example as in stores, cafes, restaurants, etc. A simple method of employing these machines is to provide each customer entering the selling p-lace with an instrumentality or key member adapted to unlock all of the normally locked filled containers of the vending` machines. Preferably, each container visibly shows its contents and bears a price notation. Thecustomer may insert his key member within a suitable key way whereby the container is not only unlocked to permit removal of the commoditybut also the key member lis marked with the price of or charge for the removable commodity. Thereafter, the purchaser mayinsert the same key member in other machines and likewise remove the contents with the at-i tendant marking of the additional charge upon his key member. The marking mechanisms of the vending machines are so arranged that the different machines mark the key member in dierent places. Furthermore, this novel vending machine-wis pro-` vided with means to indicate a repeated operation of the same vending machine by the same key member whether done in good faith or with fraudulent intent.

The object therefore of this invention is to provide an improved vending machine.

A more specific object is to provide a vending machine. adapted to be actuated by a. device or instrumentality and to mark the charge for the removable commodity upon such actuating instrumentality.

Other objects of the invention will more fully appear from the following description and the accompanying drawings and will be ointed out in the annexed claims.

n the accompanying drawings, there has been disclosed a structure designed to carry out the objects or the invention, but it is to be understood that the invention is not coniined to the exact features shown, as various changes may be made within the scope of the claims which follow.

In this embodiment of the invention which is selected for purposes of explanation, the novel vending machine is illustrated as employed ina battery or series. The machine includes a container adapted to receive the vendible commodity. As here shown the several containers are supported by means of front and rear panels 12 and its rea-rwardly extending shelves 1.3. The shelves are mounted in vertically spaced relation to support the containers. Each container is preferably formed of sheet metal shaped to provide the sides 14 and 15 and the top 16 and bottom 17. As shown in Figure 1, the front of the container is provided with a suitable closure which may be retained in locked container-closing position to prevent unauthorized access to the'contained commodity. Such closure is preferably a door comprising a frame enclosing a. pane 18 of glass to a'ord ready inspection of the container contents by the prospective purchaser. The frame in the form shown in Figure 10, consists of an l sha.ped strip 19. The marginal portions of the pane 18 are held against the inner face of the strip flange by means off a relatively narrow bar 21 suitably secured, as by solder, to the strip 19. The upper transverse edge of the pane terminates short of the strip so as to accommodate a rod 22 which extends across the door frame and is pivotally borne at its opposite ends in bearing brackets 23 secured to the front edge portion of the container. This hinged support for the container door is thus provided at its upper edge so that the door will tend to remain closed by gravitational torce. However, means are provided to maintain the door in the slightly opened position shown in Figures 9 and 10. This is simply accomplished by a leaf spring 24 4secured to the Jfront edge portion of the container and having its upper end outwardly curved whereby the door when unlocked will assume such opened position from which it may conveniently be moved by the purchaser grasping the handle or knob 25.

Preferably' a door is provided at the rear of the container so that the contained commodity such for example as food, may be covered. This rear door 26, as shown in Figure 2 may be mounted on hinges 27 and provided with a knob 28 by which it may be opened or closed by an operative. This rear.

door is not adapted to be opened by the purchaser. For example, the batt-ery of units may have their front portions accessible to purchasers permitted to pass in front of the front panels whilethe rear portions of the containers are only accessible to operatives employed by the vending machine owner .When this type of vending machine is employed where access may be had by the purchasing public to the rear thereof, then the rear door is provided with a suitable lock of any common type to which the operative retains the key. When public access to the rear of the container or containers is prevented, the rear door is simply held in closed position by means of a common form of latch carried by the rear knob 28.

Means are provided to lock the front closure in container-closing position. As here shown, there may be employed a lever system actuable Jfrom the rear ot the container. Preferably this locking means is such that it may be unlocked by a suitable instrumentality at the front of the machine and may be re-set or locked at the rear ot the machine. The front door is provided with a hook-member 29 preferably formed of stiff sheet metal and rearwardly projecting from one edge portion thereof. This hook member, as shown in full and dotted lines in Figure 9, is provided with an arcuately curved cam surface which upwardly and rearwardly extends and is engagcuble by a pin 31 transversely e\tcndiug r from and carried by the forward end of the arm 32 of a bell-crank lever mounted on the pivot 33 projecting from the side l5 of the container. |The other arm 34 of this bell-crank lever upwardlv projects and is reciprocable vfith- .in a guide 35 preferably soldered to the container side 15. The upper end of this arm 34 is terminally forked to receive a pin 36 transversely extending from the end of an arm 37 of a second bell-crank lever mounted upon the pivot 38 of the top ot the container. This lever is thus mounted for hori- Yontal oscillation. The other arm. 39 of this lever is pivotally secured to one end of a link 41, the other end of which is simi- 30 ing means in, its door-locking position.

screwed to the top and extends beyond the rear of the container to provide a handle 45 whereby this locking mechanism may be manually actuated by an operative to close the front door of the container after the commodity is placedtherein. Thus, movement of the lever handle 45 from the dotted line position shown in Figure 3l to the full line position shown therein causes the pin 31 to move downwardly'from its position 1n Figure 9 to engage the cam surface of the hook member 29 and thus to move the front door to locked closedposition. Preferably, as shown in Figure 9, the lower portion of the cam surface of the hook member is substantially straight and the pivot 33 and and pin and the door is maintained in locked position.

This locking means is normallyadapted to lremain in unlocked position while a detent means is provided to detain the locl tension spring 46 is 4mounted upch theA container top with one end held bysthe pin 47 and its other end secured to the operating lever 42. This constantly tends to pull the lever 42 so that the locking pin 31 is under constant force tending to raise it to door-releasing position.

The detaining means for this operating lever is the mechanism which is operated by an instrumentality in the hands of the purchaser. A rod 48 is pivotally secured at one end to the pin 49 carried by the operating lever and its other end slidably projects through an aperture in the upstanding flange 51 of the bracket 52 bolted to the container top. The detent means here disclosed consists of a pair of apertured metallic slides 53 and 54, although obviously a single such slide may be employed. These slides are mounted within the substantially U-shaped housing orslideway 55 bolted to the-container top. The forward ends of the two slides are formed with oppositely offset heads which may be integral or may be pro- 55 vided by blocks 56 and 57 welded thereto.

These slides are under tension constantly htending to force each to its forward position against a limiting stop on the container top. Such tension is similarly provided for i0 each slide by means of pins 58 and 59 secured to the heads 56 and 57, and by compression springs 61 coiled about the pins and held between the heads 56 and 57 and the apertured bearing brackets 60 and 62 c5 secured to the slideway '55 and flange 51 respectively. Obviously, retraction of a slide places its spring 61 under lincreased compression tending forwardly to thrust the slide. The housing or slideway 55 is provided with alined apertures therethrough so that the rod 48 may extend therethrough.

When the door is in closed locked position,

as shown in Figure 3, the rod 48 extending through its guiding lflange 51 projects through the aperture in the adjacent side of the slideway and abuts against the side of the adjacent slide. A with an aperture therethrough in order that, when the two sides are rearwardly moved so that their apertures are in alinement with the apertures of the slideway, the rod 48 may be projected through the thus-alined apertures under tension of the spring 46 and the operating lever thus ypermitted tensionably to move to door-releasing or unlocking position. Such rod and slide position is shown in Figure 4.

The machine is thus adapted, upon rearward movement of the slide detents by a suitable instrumentality or key member manipulated by the purchaser, to open the door to permit removal of the commodity within the given container.

Such key member is here shown as in the form of a piece of flat sheet material for ,which a relatively stiff paper is suitable such as the card 64. This key card is adapted to be'inserted by the purchaser within a'key way'formed in the machine and` upon rearward movement, to release the locking mechanism. The key way is provided by a fiat metallic base 65 slidably mounted in the opposed angled guides 66 carried by the container top. This base is preferably slidable in order that it may be forwardly moved as a unit in order to ermit convenient access to the mechanism carried thereon for purposes of alteration, adjustment, inking, etc. A mouth 67 is mounted upon the forward portion of the base and projects through the front panel v12. This mouth is formed preferably of sheet metal to provide a flaring upper face rearwardly leading to a relatively narrow elongated aperture of suiiicient. height to permit a guided insertion and rearward passage of a key card. The rear edge 68 of the relatively shortened portion of the base shown on the left rear in Figure 3 providesthe abutment or stop which limits the normal forward tensioned movement of both slides 53 and 54.

As shown in Figures 3 and 4, the key Each slide is provided card is preferably formed with two cutlll push such single slide rearwardly until its aperture is alined with the slideway .apertures to permit passage of the rod 48. Herein, however, two slides are shown and their apertures are, as indicated in Figure 4, offset, that is are at different distances from their respective blocks 56 and 57. Hence, to attain alinement of apertures the slides must be rearwardly pushed different distances. Such is the object of the stepped edge of the key card as is operatively shown in Figure 4. While two such detent slides are shown it is obvious that more may be employed with consequent change inthe key card. Furthermore, the apertures in the slides may be differenty spaced so that the key card must be differently stepped in order to effect unlocking. The card is guided in its rearward working travel by the two angled strips 72 secured to the base 65.

Means are provided to mark the unlockin instrumentality such as the key card 64 wit a charge indicat`on of the commodity which I is thus removably delivered. A convenient form of marking means is type adapted to imprint a numeral or numerals upon the key card. In the type device here shown, the type 73 is peripherally mounted upon a collar 74 loose upon a shaft 75 mounted in bearings provided by alined holes in the opposed bearing plates 76 upwardly projecting from and carried by the base 65. One end of the collar 74 has fast thereon a pinion 77 which is constantly in mesh with the teeth 78 of a rack bar 79 slidably mounted upon the base 65 between the adjacent card guiding strip 72 and bearing plate 76. This rack bar has a rear portion which is offset in the path of a card so that as the card is rearwardly moved the rack bar is simi- `larly moved and the type-bearing collar 74 is rotated. Rotation of the collar 74 causes the peripherallyV borne type 73 to print the card 64 as it is rearwardly moved to unlocking position. It should be noted that the radius of the pinion 77 should be in proportion to the radial distance of the type from its shaft so that the type 73 will be actuated at the same linear rate of speed as the rearwardly moving card. A convenient means of inking the type consists in the provision of a feed` roll 8l mounted upon the shaft 82 loosely borne in the upper set of holes shown in the bearing plates 76. Preferably a leaf spring 83 is mounted upon the base 65 and presents'a convex tension surface to a card so that the card may be held against the type during the printing movement.

When these vending machines are used in a series, they usually contain different commodities of which a purchaser may desire one or more. Hence, the markingl means must be so arranged that each machine will mark the same card in a different place. Such is the purpose of the plurality of holes shown in the two bearing plates 76. For

example, when the type-bearing shaft is moved from the ition shown in Figure 3 and installed within bearing holes to the rear of those shown in such figure, an inserted card will obviously be printed closer to its leading edge than is the case when the shaft is in the position shown in Figure 3. Likewise, the type 73 may be moved longitudinally of the collar 74 so that the card may be thereby printed in a different vertical space. A suggestion of such printingr spaces is shown in Figures 3 an'd4 by the lines defining rectangular spaces upon the upper surface of the key card 64.

It is desirable in order to revent a purchaser ofrom inserting a car twice in the same container with the fradulent intent that the marking mechanism will simply cause the second marking to be accurately superposed upon the first and hence but a single marking to appear. Therefore, means are provided to indicate such a repetition upon the same card. This is conveniently accomplished by successively changing the actuation of the printing shaft in timedL relation to movement of the card. The offset portion,of the rack bar, heretofore referred to. consists of ablock 84 secured thereto and pron jecting Within the key Way or path of a key card. A rotor 85 is mounted upon a stud 86 carried by the block 84. The face of this rotor which is resented in the path of the inserted key card is provided with a plurality of stops 87, in the form of studs, each projecting a different distance from the rotor face. For example, the card 64 is shown in Figure 8 as in engagement with the longest stop 87. Obviously the rack bar will immediately be rearwardly moved by the card. However. if the smaller stop 87, shown at the top of the rotor in Figure 8 were in lowermost position, it is obvious that the card would have lto travel the distance between the ends of these two stops before the rack bar is rearwardly pushed. The result of this slight relative movement between the tvpe and card is that the second printing is slightly offset from the prior printing upon the same card. Of course if onl a single imprint is made on any given car this relative movement is immaterial. Four such stops 87 are preferably provided upon the rotor in order to give three repeated markings upon the same card, in other words, the same card may be marked four times and show each repetition. It is preferable also to provide the type numeral with an additional tell-tale such as a dash 88. A repeated'marking is shown in the fragmentary view of a marked card in Figure 11.

Means are provided automatically to present successively the different stops 87 to a y Thus, when the slides are moved to properk card." This means is automatically operable upon re-locking of the door. The periphery o the rotor 85 is provided with ratchet teeth 89 adapted to be engaged by a device which is connected to the operating lever 42 so that the rotor is turned a quadrant upon each resetting of the lever to lock the door. A rod 91 is provided with a. downwardly offset end which is pivotally mounted in an aperture in the operating lever, the other end portion of this rod is slidably borne by an aperture in the guide 92 upstanding from the container top. A pin 93 forwardly extends in a horizontal plane from the rod 91 and bears an end of the pawl 94 normally downwardly held by the wire spring 95 secured to the rod and pawl. When the operating lever is permitted to move to opening position as shown in Figure 4, the pawl 94 idly moves over the rounded surfaces of the ratchet teeth 89 in position to engage a tooth and turn the rotor a quadrant upon manual re-setting of the operating lever.

The rack bar and itsE rotor are normally held in forward position by the compression spring 96 coiled about the rear portion of the rack bar between a bearing block 97 fixed to the container top through which the bar slides and the rotor block 84. Hence, means are provided to prevent tensioned return of the rotor block and rack bar to normal forward position upon withdrawal of the key card in order that the rotor may be changed by the pawl upon re-setting of the operating lever. To this end, a wire 98 having an upwardly offset end portion rearwardly projects from the rotor block. As is sho-wn in Figure' 4, when the key card has rearwardly moved the block 84 and rack bar, the wire 98 passes behind the path of the rod 91.

alinement and the rod 48 is thrust therethrough, the operating lever 42 moves to project the rod 91 in front of the offset end of the wire 98 whereby the rotor and rack bar are thereafter held in a fixed position. Resetting movement of the operating lever 42 causes retraction of the rod 91 both to cause the pawl 94 to turn the rotor to present a different stop and thereafter to release the'wire `98 to permit the changed rotor to move to forward position.

The rotor 85` is'normally held against the rear face of the block 84 by means of a tension spring. This spring is coiled about the headed stud 86 and has one end bearing against the block and the other end against the head of the stud. This spring is prefure 6. A stop for the tensioned forward movement of the rack bar is provided by the extension 100 of the adjacent bearing plate 76. lPreferably also a stop is provided for limiting rearward -movement of the key card. ch stop consists of a block 70 scoured to the upper face of the container. This stop 70 is shown in card-limitinfr position in Figure 4. The advantage of t e employment of such a stop resides in the fact that the card may thus push the lslides to the desired aperture-alining position and hence prevent the slides from over-running such alined position.

The base and associated parts substantially constitutes a tray which, as heretofore stated, lmay be pulled out the front of the machine for alteration, etc. A latch is provided to retain the base 65 in normal operative position. An angled leaf spring 99 (see Figure 8) is riveted -to the under face of the container top and has its angled portion adapted to be normally seated within holes cut in the top 16 and the base 65.

Preferably, means are provided to prevent the insertion of a key card having a false cover or sheet of paper laid thereon to prevent marking of the card upon unlocking of the container. Such means is provided by a bar 101 of relatively soft material having a high coeflicient of friction with paper, such as rubber. This bar 101 is held (see Figure 8)l by means of a clamp bracket 102 secured to the mouth 67 so as to be positioned-to contact with the surface of an inserted key card.
