VENDING Application lledpril 28, 1926. Semi No. 105,541'.

My invention relates to vending machines and has for its object the provision ot a machine from which a plurality of artlcles or packages may be selectively dispensed. The

lnvention seeks to provide a mechanism in which a plurality of articles or packages may be viewed by a purchaser and a selected package or article brought into position to be withdrawn from the machine by the customer. The invention also has for its object the provisionV of means whereby the withdrawal of the article or package Will be )direvented until the proper coins have been eposited, and another object of the invention is to provide novel means whereby after the deposit of thecoins the package or article will be rendered accessible. These stated objects, and other objects which will inci' dentally appear in the course of the following description, are attained in such a mechanism as is illustrated in the accompanying drawings, and the inventionresides in certain novel features which will be particular-1y pointed out in the appended claims.

In the drawings:

Fig. 6 is a horizontal section on the line 6-6 of Fig. 5;

Fig. 7 is a detail showing a corner of the door;

Fig. 8 is a bottom plan view of a portion of the turntable or package carrier.

The casing 1 may be of any preferred formor dimensions and may be constructed with one compartmentor a plurality of comartments each containing a mechanism em iodying the invention so that within a.V limited space a large variety of merchandise may be displayed and vended. The top of the frame or cabinet is covered by a pane of glass or other transparent material 2, and, if desired, the sides of they cabinet may be made of the same material so that the merchandise displayed for sale may be readily viewed by a prospective customer. The merchandise is arranged upon .a turntable ortray 3 upon which are secured a plurality of radial par titions 4 whereby a -plurality of compartments is produced, and this tray is provided at its center on its under side'with a pivotl post or stud 5 adapted to seat within a bearing 6 upon a supporting frame 7 which is engaged u on cleats or other supports 8 within the rame or cabinet so that an empty tray may be readily Withdrawn and a filled tray.; substituted therefor. It. will be un derstood that the back of the cabinet or enclosing frame is provided with a removable wall or a door which is normally locked, so that the insertion Aand removal of the trays will be easily accomplished. The tray is provided on its under side with a circularl gear rack 9 meshing with a pinion 10 on the inner end of a shaft 11 which is journaled in suitable bearings provided therefor in the front wall of the cabinet or frame and equipped Vat its outer end with a turning knob or handle 12, as shown.- When a pur- Chaser desires to obtain some article or package displayed upon the tray, he rotates the shaft 11 t roug manipulation of the knob 12 in an obvious manner so that the tray is rotated about the center 5 until the compartment containing the desired article or ackage is brought into the delivery ositlon.

In order that the tray may move easily, rollers 13 are provided u on the sup orting frame 7, as shown in ig. 3, and t e tray rests upon these rollers so that it will move easily and will be supported in a horizontal position at all times. Within the cabinet at the front' side of the same is a hood 14 of proper form and dimensions to extend over and enclose the particular compartment on the tray from which the goods are to be removed, and this hood communicates directly with the opening 15 in the front wall of the casing, which opening is normally closed by a door 16.

In the illustrated embodiment of the in vention, the door 161is mounted for sliding movement in channels or-tracks 17 provided therefor at the top and bottom of the door opening and is normally held against movement by a bolt 18 mounted vertically in suit able guides provided'therefor below and at one side ofthe door opening and pivotally attached at its lower end to a lever or trigger arm 19 which *is pivoted between its ends upon a bracket or supporting frame 20 secured within the cabinet adjacent the door opening. The inner end of this lever or trigger arm 19 extends upwardly and is equipped with a roller 21 which bears against the under side of the carrier or tray 3 and is adapted-to engage or seat in any one of a series of'recesses 22, provided in the bottom of the tray, as the compartments thereon are brought under the hood14. 1A. spring 23 is attached to therfront portion of the arm 19 and to a. ixedfpoiiit von the frame below the said arm so that it terds constantly to retract the bolt 18 and to swing the roller 21 upwardly. When the tray is rotating, therollere21 bears against the flat uninterrupted surface of the tray and is, consequently, depressed inst the tension of the spring 23 so that t e bolt 18 is projected into the path of the door 16 and revents opening movement of the door. en the rotation of the tray brings a recess 22 over the roller 21', the spring at once swings the roller into the said recess and the tray' is then stopped but if the compartment thus brought under the hood 14 does not contain the articular merchandise desired by the purc aser, the rotation of the tray, may be continued until the proper merchandise has been brought into the delivery osition. As long as turning force is applic to the knob 12, the tray'will be rotated inasmuch as no great amount of force will be required to overcome the seating of the roller 21 in the notch 22, but if the rotation. of the shaft l1 be stopped with the roller en aging a seat or recess 22, the tray will be eld stationary and the bolt 18 will-remain in its retracted position so that the door 16 may be opened.

When the bolt 18 is retracted as just described, it removes one obstacle to the opening movement of the door but the door cannot be opened until coins have been inserted inasmuch as the coin chutes 24 and 25 proect into the path of the dooigthese tubes eing pivotally mounted, as at 26 u 'on the front wall of the cabinet and yieldab y held. with their lower ends in the door by a spring 27 disposed etween the u per extremity of the chute and the a )acent portion ofthe front wall of the cabinet. Formed in the wall ofA the cabinet at the side of the door opening 15 4and in such position that they register with the lower ends of the respective coin chutes 24, '25, are

y coin tubes

28, 29 which open at their lower ends into a moneyV compartment 30 in which I may be disposed a coin box .or drawer 31.

Within the cabinet and mounted upon a portion of the bracket or frame 20 are a pair of pivoted

dogs

32, 33 which project forwardly into the

respective coin tubes

28, 29 and serve as stops to arrest the descent of coins inserted through the respective coin chutes. The

dogs

32 and 33 not only extend into different coin tubes but are also disposed at dierent elevations, as will be understood upon .reference to Fig. 4, and the ath of the.

exact position of these dogs may be determined by the coins which it is intended to require for the operation of the machine. In the present instance, the tube 29 requires the admission of two nickels, indicated 8,1234, while the tube 28 is intended to receive a cent as indicated at 35. The

dogs

32 and 33 are held in their operative position by

bolts

36 and 37, respectively, which are disposed vertically and slidable in guides 38 provided therefor in the internal sup rtin bracket 20. The upper en s of

t esebolts

36, 37 are beveled, as shown at 39,.and they project into the path of the door. 16, as will be understood, the length and position of. the bolts being such that normally a straight side or edge will be presented to the door and, consequently, the movement. of the door will be prevented by contact with the said edge. It will also be noted upon reference to Fig. 4 that, when the coins are arrested by the

dogs

32, 33, they will project above the u per ends of the respective coin tubes into t e lower ends of the coin chutes so that the coin chutes will continue to block the movement of the door and prevent access to the interior ofy the casing through the opening 40 which is provided to accommodate the coin chutes and permit the opening of the door. TheV coin chiites are swung out wardly by the action ofthe door 16 and in order that they may move over and away from the coins, they are provi-ded .in their inner walls at their lower extremities with notches 41 whereby they will clear the coins as they swing outwardly. To effect this outward movement of the coin chutes, a .cam 42 is providedI on the door and proyects therefrom in position to ride against the side and inner wall of the chutes and thereby force the same-outward against the strength of the spring 27 in an obvious manner. If coins have been inserted in the machine as re aired, the opening movement of the door wil cause a projection 43 thereon at the lower edge of the same to ride upon the projecting coii and press the same downward within thel respective coin tube so that the bolt 36 017317 disposed at the back 01E-said tube willi'he depressed, it beingI noted that the dogs.I 32, 33 pass through and seat in notches in the respective bolts so that downward pressure upon the coins tending to swing the dogs downward will transmit movement to the respective bolts and impart thereto a suicient depression to bring the beveled edge 439 of the same into the path of the door, whereu on the continued movement of the door wi l cause it to ride on the bolt and depress it to the limit of its movement. Access to the compartment within the hood 14 cannot be had until the door is fully opened and the depression of the first bolt 37 will not permit the door to be full opened inasmuch as it must still clear an operate frame or `the second bolt 36 so that the mechanism cannot be actuated until the proper coins have been deposited. On the inner side of each bolt is a lu 44 which bears upon a rocking arm 45 nlcrumed upon the inner supporting frame 20 and having its free end connected to a link 46 which depends to and is pivotally attached. to a rocking arm or lever 47 also fnlcrumed upon the inner supporting frame 2O and extending lnwardly therefrom. The inner end of this arm 47 carries a bolt or locking pin 48 which is guided by an eye 49 at, the inner end of an arm 50 forming a part of the frame or bracket 20. This bolt or lockingl pin 48 is normally held in its lowered position by a spring 51 attached to its lower end and to a fixed part of the cabinet and has lts upper end arranged toy enga e in one of a series of sockets 52 provide in the bottom of the tray 3. When this bolt 48 engages a socket 52, the tray will be held against further movement and it will be now understood that the

bolts

36, 37 are so located that, when the door 16 is opened to permit Vwithdrawal of the article or package within the hood 14, both bolts will be held in their lowered position and the bolt 48 will, consequently, be held in engagement with the tray and the tray cannot be moved to bring another article or package opposite the door opemng until the door has been again closed and the mechanism thereby reset for the insertion of additional coins. When the door is returned to closed position, the spring 51 withdraws the bolt 48 from the tray andprojects the

bolts

36, 37 into their upper posltions so that the door'cannot be agrazin opened until coins have been inserted.. o .facilitate the movement-of the door 16, it is provided with a knob 53.

It is thought the operation will be fullyy understood rom the foregoing description, taken in connection with the accompanying drawin After the tray has been set by Y manipu ation of the knob 12 and the coins Y the corner of the have been inserted, the door is pushed toward the opening position and the cam 42 thereon will ride against the coin chutes and swing them outwardly, the continued movement of the door bringing the lower edge thereof and the presser 43 onto the upper projecting edge portion of the respective coins so t at they will be depressed and an initial lowering movement imparted to the

bolts

36, 37 sufficient to bring the beveled edges thereof into osition to be engaged by oor, whereupon the continued movement of the door will depress said bolts and the lowering movement of the bolts will be transmitted through the roeking arm 45 and its connections to the bolt 48 so that the tra will be locked against movement. The 4oor will, of course, extend across the upper ends of the bolts and will maintain the locked position of the tray until the door has been moved toward the closed position and, in order to clear the bolts, the door must be moved until it is nearly closed. If it be not fully closed, the cam 42 will prevent the return of the coin chutes to their inner operative position and the bolts will-project upward into the path of the door so that the door cannot be again moved into open position and access to the hood 14 will be, consequently, prevented. When the tray is moved so as to bring a second compartment into the discharge position, the roller 21 will be depressed and, consequently, an upward movement will be imparted to the bolt 18 so that, if the door` be not fully closed, the upward movement of this bolt will be prevented and, therefore, further movement of the tray cannot be had. When the

bolts

36, 37 4are depressed by the door, the dogs or coin rests 32, 33, are swung downwardly and inwardl out of the paths of the coins which then dlop into the coin box.

It will be readily noted that l have pro vided a simple and compact mechanism whereby merchandise may be vended nutoniatically or without the services of a salesman, and the parts are of such construction and arrangement that they are not apt to get out of order. A great variety of merchandise ma be dispensed through the use of my mac ine and the articles may be changed from time to time as may be deemed desirable. The size of the coin tubes and coin chutes and the relative arrangement of the mechanism directly operated by the coins may be varied as may be necessary to adapt the machine to merchandise of any particular value. f

In order that the tray 3 may be held firmly tothe pinion 10 and the roller 21, a presser roller 60 is preferably mounted upon the bracket or inner supporting frame 20 to ride upon the upper surface of the tray and thereby prevent the forward ortion of the same tilting or rocking in snc a manner as will interfere with the successful operation of the mechanism.

Having thus described the invention, I claim:

l. In a vending machine the combination of a casing, a tray movahl mounted in the casing, a door mounted in t e casing and controlling access to the tray, a bolt mounted in the path of the door, and coin-controlled means whereby opening movement of the door will retract said bolt and positively lock the tray against movement.
