As shown on the drawings:

The reference numeral 1 indicates a back plate or mounting plate having a plurality of apertures therein for the purpose of receiving mounting screws to hold the mounting plate in position 'upon a wall or support. Hinged to the upper edge of the mounting plate 1 is a cover 2. Integrally formed along discharge slot 8 the middle portion of which is enlarged as indicated by the reference numeral 9 while the end portions 8 are narrow, Rigidly secured to the inner surface of the container front plate 5 is the flange 10 of a stationary cup guide channel 11. The stationary guide channel 11 is slightly inclined as illustrated in Figure 2 with the upper end of the guide channel nearer the side wall of the container than the lower end of said guide channel. Struck from the upper end of the trough portion of the guide channel 11 is an outwardly and downwardly curved guide finger 12 over which an endless cup feed chain 13 is trained. The chain 13 passes downwardly through the guide channel 11 and near the bottom of said guide channel,

- idly secured to or formed on one end of a shaft 16, one endof which is journalled in a flange formed on the lower end of the guide 11 while the other end of said shaft is journalled in an opening in the guide flange 10. Also mounted on the shaft 16 is a ratchet 17 adapted to be actuated by means of a pawl 18. The pawl 18 is supported on an upwardly directed projection or lug 19 which is integrally formed on one end of a cam plate or bar 20.

The middle portion of cam bar 20 is enlarged at 21 and is provided with an inclined cam slot 22. The cam bar 20 is provided with longitudinal slots 23 and 24 (Figure 6) through which pins 25 project. The pins 25 support the cam bar in position. The pins 25 are secured to the lower portion of the flange 10 and the flange 26 of a movable guide 27. One margin of the flange 26 is turned at an angle to form a side flange 28. The flange 26 of the guide member 27 is provided with transverse slots 29 (Figure 2) through which the pins 30 project with the ends of said pins secured to the front wall 5 of the container. The movable guide 27 is also inclined with respect to the side wall of the container so that the two guides 11 and 27 are spaced farther apart at their upper ends than at their lower ends so that when a stack of flat nested cups is positioned between said guides their downward movement is retarded and the cups are slightly expanded to permit the cups to move downwardly toward their discharge position when advanced by the feed chains. Slidably mounted upon the flange 26 between one portion of the guide 27 and the side flange 28 is a slidable cam plate 31 having a pair of cam slots 32 therein through which the pins 30 project. The upper end of the cam plate 31 is bent over at an angle to form a finger piece 33 to permit the cam plate to be actuated to cause the guide 27 to be moved inwardly or outwardly away from the stationary guide 11.

Struck from the upper portion of the movable guide 27 is an outwardly and downwardly curved finger or lug 34- over which a second endless cup feed chain 35 is trained. The chain 35 passes downwardly and is trained around a sprocket secured on one end of a shaft 37 the ends of. which are journalled in suitable flanges on the lower end of the guide 27. Also mounted on the shaft 37 is a ratchet 38 adapted to be actuated by means of a pawl 39. The pawl 39 is pivotally supported in a downwardly directed lug 40 which is integrally formed on the lower edge of the cam bar 20 (Figure 6 Also secured to the lug 40 is one end of a control spring 41 the other end of which is secured to a pin 42 secured to the inner face of the front wall 5 of the container.

The cam bar 20 is adapted to be actuated angle at 45 (Figure 1) to permit the lower end of the plate 44 to project out through the enlarged middle portion 9 of the cup discharge opening 8-9 of the container. The lower projectin end of the slide plate is shaped to atfor a thumb piece 46 to permit manual actuation of slide plate 44. The slidable thumb plate 44 is provided with longitudinal slots 47 through which pins 48 project. The pins 48 are secured to the inner face of the lower portion of the front wall 5 of the container.

The operation is as follows:

The improved dispenser of this invention is of the feed chain type and embraces the mounting plate 1 which is adapted to be secured by means of screws or other suitable means to a wall or other support. The mounting plate, of course, is secured in position when .the cover 2 is raised and the container 45 is swung into open position. \Vhen the container is in open position an operator may engage the finger piece 33 and pull outwardly on the same thereby causing the cam plate 31 to slide outwardly over the flange 26 of the guide member 27. Outward movement of the cam plate 31 causes the cam slots 32 to pass over the pins 30 thereby causing both the cam plate 31 and the guide 27 to slide transversely or move outwardly away from the stationary guide 11. The slots 29 in the flange 26 permit transverse sliding of the guide member 27. It will thus be noted that the guide 27 is adapted to be readily moved away from the stationary guide 11 to increase the distance therebetween so that a stack of flat nested cups may be readily inserted through the top of the container between the separate guides 11 and 27 with the creased upper corners of the nested cups in contact with the conveyor chains 13 and 35. The container may thus be filled with a stack of flat nested cups after which the operator manually pushes (l(l\\'ll\\'tll'tll on the linger piece 33 thereby causin the movable giiide.27 to be moved toward the stationary guide it to slightly clamp the nested cups between the inner laps of the endless conveyor chains 13 and 35. The two guides 11 and 27 converge downwardly so that the cups in their downward movement through the container are slightly compressed to partially open the cups.

With the container filled with a stack of nested cups and with the movable guide returned to normal position to hold, the cups in position the filled container is swung upwardly into the position shown in Figure l and the cover 2 closed to hold the container in vertical position ready for use.

Normally the mechanisms are as illustrated in Figure 2 with the control spring 41 acting to hold the cam bar 20 in the position shown in Figure 2 with the thumb piece 46 in its lowermost position disposed in front of the projecting tip of the lowermost cup which projects out of the bottom of the container through the restricted slot 8-9.

The container is now in a position ready to be used. To remove a cup from the container the thumb of an operator is pressed against the thumb piece 46 while the forefinger of the operator is engaged against the back of the tip of the lowermost cup. The thumb piece is now pushed upwardly thereby causing the plate 44 to slide upwardly with the pin 43- moving in the cam slot 22 of the cam bar 20. The cam bar 20 is thus moved transversely from the position shown in Figure 2 toward the right hand side of the container looking at Figure 2. With the transverse movement of the cam bar 20 the pawls 18 and 39 simultaneously engage the ratchets 17 and 38 thereby causing rotation of said ratchets and the respective shafts 16 and 37. With the rotationi of the shafts 16 and 37 the sprockets and 36 are simultaneously rotated thereby causing operation of the endless conveyor chains 13 and 35 through a predetermined distance. The inner laps of the chains having engagement with the corners at the open ends of the cups cause the stack of cups to be fed downwardly in the container a predetermined distance towards discharge position. Simultaneous with the pushing upwardly of the thumb piece 46 the thumb of the operator slips downwardly off of the thumb piece into engagement with the front portion of the tip of thelowermost cup so that the tip of the cup is engaged between the thumb and the forefinger to permit the cup to be easily drawn from the container out through the discharge opening 89. As the lowermost cup is removed from the container the spring 41 acts automatically to return the cam bar into the position il-. lustrated in Figure 2 thereby retracting the pawls 18 and 39 and at the same time causing the plate 44 to lee-moved downwardly to again position the thumb piece 46 in front of the next cup which now projects from the bottom of the container.

It will thus be seen that each time the thumb piece 46 is pushed upwardly the chains 13 and are simultaneously actuated to cause downward feeding of the stack of cups'within the container a predetermined distance each time a cup is removed from the bottom of the container.
