To all whom it may concern:

Be it known that we, MELVILLE BLBAIRD and GEORGE A. WALLS, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have in- ;vented certain new and useful Improvements in Vending Machines; and we do dedlare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac-companylng drawings and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates I to coin-controlled vending machines and particularly to a machine for vending paper cups capable for use at drinking fountains and the like.

The invention contemplates the provision .of means whereby the paper cups may'be contained within a receptacle and rendered inaccessible unless a coin, check or token of authorized denomination is introduced into certain novel ejecting mechanism, which constitutes one of the novel features of our invention, there being means provided whereby the insertion of an illegal coin, check or token through the discharge open ing in the receptacle will cause the opening to be closed so that access to the cups cannot be had.

In the drawings,

Fig. I is a perspective view of a vending device constructed in accordance with our invention, parts being broken away to show the interior construction thereof.

Fig. II is a fragmentary, vertical, longitudinal, sectional view of a device embodying our invention.

Fig. III is a view, showing a part of the floor and a portion of the ejector.

Fig. IV is a bottom perspective view of the ejector and the coin-receiver inejecting position.

Fig. V is a similar view showing the ejector in cup-engaging position and the coin being released.

Fig. VI is a detail view of one of the cups.

Fig. VII is a fragmentary, perspective fragmentary, perspective and, Fig. VIII, is a detail viewof the slotted guideon the ejector.

View of the jaw end of the ejector actuator,

swinging gate or door9, the inward swinging movement .of which is; adapted to be opposed by the stop 10, struck up. fromthe floor 3, asv shownin FigL III, sothat in the event that an. illegal T instrument .is forced through the slotted hood 8 from the exterior of the receptacle. its passage will be arrested by. the gate 9 although the ejection of the cups in an authorized manner, will not be seriously opposed.

The floor 3 of. he receptacle is shown providedwith a slot 11 over which is adapt-v ed to slide an ejector bar 12 having an up,

wardly curved front end 13 and, a hooked end 14: at its rear, the parts 13 and 14 being designed toengage parts of the cups. 7, as will appear hereinafter.

Suspended from-the bar 12 and'slidable along the under face of the floor 3 is a plate 15 fastened to the bar between theedges of.

the slot 11 so the movements of the plate 15 and bar 12 will be synchronous. The plate 15, which constitutes part of the ejecting or delivery device, isprovided' at one side edge witha vertically extendingguide member 16 having a flange. 17 provided with a slot 18 :through which a set, screw passes into the plate 15 whereby the guide may beadjusted with relation to the plate. Bv reference to Figs. IV, V and VIII it will be observed that the guide is provided with a lateral groove 20. parallel with the slot 11 and that in the floor of the groove 20 is a through slot 21 adapted to align with the coin slot 22, the inlet of which is at the front of the receptacle, as shown at 23, there being a return slot 24 provided in which is the; rear end of the guide when the bar- 26 y 26, the front end of which the 'frontpanel of the receptacle and is provided with a stop pin 27. The rear end of the bar 26 is cut away to provide a coin engaging jaw 28 of a length substantially the length of the slot 21 and adapted to register therewith, but the rear end of the bar 26 extends beyond the rear end of the guide 16 and 'carr'ies'a stop shown as a cross pin 29 so that the stop may engage against is pulled out and therebycausethe ejector to move Ito ejecting position. WVhen, however, the bar 26 is pushed inwardly, its movement will be independent of the guide unless opposed by a coin, check or token introduc'ed through the to be held in the guide by a coin support coin slot 22 adapted 30, carried by the plate 15.

The coin support or retainer for the. coin receptacle is shown as consisting of a lever pivoted to the plate 15 at 31 and normally urged by aspring 32 to coin-releasing position but the spring will be opposedby a cam rail 33, along'the edge of which the arm 341maytrav'el toward the end of the inward stroke ofthe bar 26am the ejector, Therefore, it will be seenv that when the cheek, coin or token is introduced into the machine, it will pass into the slot 22 and drop iiito the receiver, passing partly through the lot 21 where its movement will bearrested by the coin support 30. During this time the parts will" be in substan tially the position shown in F ig. IV. Up on a rearward movement of the bar 26 the jaw28will be caused to engage the coin because the coin will fill the gap between the movement has been sufficient to cause the a lever arm 34 to ride eff theedge 33, where upon the spring 32 will urge the coin re .tainer 30 away from the slot 21, permitting the coin to' d rop into the coin receptacle 5. The ejector nd its actuator thereupon become disconnected for movement in one di-f rection but the return movement, that'is, an outward movement of the bar 26 will cause the stop, shown as a cotter p'in'29,-to engage the rear edge of the guide 16 so that the ejector and its actuator must move together in an outward direction or toward the slot 6. The movement of the ejectortoward the slot will cause the lip 13 to engage the outwardly curled 513236 of p 7 and the upturned end 14L to engage the edge 37 of the cup 7 o that the cup will be moved up the spring stop 10, between it and the finger 38 and pass the outwardly opening gate 9 so that its end will protrude through the slotted hood 8, whereupon it maybe removed. i

It is to be'understood that the cups will be introduced into the receptacle in stacks, the portions 36 extending downwardly and rearwardly so that the end 39 will be disposed toward the ejecting slot of the machine, enabling the cups to be easily engaged bytheslidel2. W 7

The ejection of the cup will be effective in bringing the plate 15 and its appurtenances to the front ofthe machine and it cannotyagain be retracted to, cup-engaging position unless the guide j-is oconnected to the actuator 26 by another, coin, check or token of appropriate denomination. Upon the presentation of a proper coin, the ejector and its actuator may again be locked together and the machine permitted ,to function. a 7 Iran unauthorized coin, check or token is inserted through the opening 23, the magnet 25 will deflect it to the return slot 24 so that it will be returned to the customer.

WVhat we claim and desire to secure by Letters-Patent is p In combination, an article container, a reciprocatory-ejector, a coin receiver carried by the ejector, an ejector actuator having a part to abut against the coin receiver,.depending lugs adjacent to the coin receiver. and spaced apart to provide guides, a. piv; otedmember having one end Weighted and the other end movable between the lugs and normally lying in a position to obstruct the passage of a. coin through the coin receiver, and means for tilting the pivoted member to release the coin.

In testimony whereof we aflix our signatures. v v I MELVILLE B. BAIRD; GEORGE A. WALLS.
