This invention dispensing machines, and

particularly to machines for dispensing actuation of a customer operated means.

Another object is to provide a machlne of this character which will, upon actuation of a plunger or push-rod, place a drinking I cup in ,position to receivey the liquid, and

subsequently deliver Athe charge of liquid into the cup.

Another object is to provide, in a machine of this character, a vcharge measuring device, in association with a liquid container,.

which will effectively .prevent leakage of the liquid from the container, when in liquid receiving position, or when in charge delivering position. Y

Other objects and advantages will be apparent from the following description when taken in connection with the accoman ing drawingsf p 1151r vthe drawings:

Figurev 1 is a top planview of the oper-- ating mechanism 1n normal position.

Figure 2 is a front elevatlon of. the same.V Figure a .vertical longitudinal -sectional viewon the line 3-3 of 'Figure-,1;

Figure 4 is a vertical longitudinal sectional view on the line 4 4 of Figure 1'.

Referring particularly to the accompanying drawings, 10 represents a portion of a tank, which is adapted to contain the liquid to be dispensed. .Formed integrally Awith the lower portion of the side wall- .of the tank,.and projecting outwardly therefrom, is anipple 11, andV formed on the lowerside of the outer en d portion of the nipple is a -downwardly and outwardly inclined spout 12. In thecenter of the'outer end wall of the nipple'there isvformed A.an opening 13.

' Inthe surrounding-wall of the inner end of the 'pple, or where'the 'bore thereof enters the tank, there is formed-a boss 14.

@langem Openings -18 Slidable in the' bore of the nipple is ahollow cylindricalcharge measuring member 15, the' inner end of which is formed with a' beveledhead 16 arranged 'to seat against the boss 14, when the said member is in its outermost position. In the wall of the member r15, adjacent the head 16, are the elongated longitudinally extending openings 17, whlle -circular opening are formed in said relates to new and useful member a' 'suitable distance outwardly'of the i openings 17, but extending circumferentially of the member. These openings 17 and 18 are spaced short distances from each other, so that each circular series of openings is, in effect, an opening or slot, extend- 'V ing completely around the member', whereby to facilitate the entrance of liquid from the tank, into the member, and also to facilitate the discharge therefrom into the spout 12.

.Both'ends of the cylindrical member 15 are the same being held in position on the .stem

by means of theterminal nut 21. Encircling the stem, and bearing against the said collar 20, and the Aend wall of the nipple, is a coil spring 22, which normally urges the cylindrical member outwardly, so that its openings 18 are in registry with the inner endof the spout 12. Mounted onthe outer end of the nipple is a bracket 23, andsupported on this bracket, at one side of said nipple, is. aA holder vfor sanitary pa 'er cups, said holderibeing designated by t e numeral 24. Thisholder is provided with an operatingl arm 25, projecting transversely of the outer endof the nipple, for causing the single delivery ofvthe\-paper.cups. Mounted on the bracket 23, at the other side of the nipple, is a horizontally disposed table 26, said ltable having a longitudinal slot '27 formed therein, Yandat, the forward end of said table there is formed .fa comparatively small 28. Secured to the lower face ofthe table 26, and spaceda short dis- 33, and engaged'on the upper end' ofthe pin is the ongitudinally slotted ortion of a link 34, whileV the longitudinally slotted portion of a similar-link is engaged on the lowerend .of the in. Extending vertically through the ta le and plate, .at

tance'therefrom, is .a plate 29; alsohaving Slidable longitudinally between mo i Y plate, both above and below thereof, is a pin 'side of the slots thereof, adjacent the nipple 11, is a pivot pin 36, and engaged on the upper portion of this pin is the vertical pivot portion 37, of a lever 38, the other end of said lever being pivotally connected with the cup operating arm 25, by means of the link 39. On the lower end of the pin B6 is a centrally mounted rock lever 40 supported on the lower faceof the table is a rock lever 42, one end of which is pivotally connected with the other end of the rock lever 40, by means of the link 43. The other end of the rock lever 42 is formed with a yoke 42', the ends of the arms of which are engaged in the groove of the collar 20, for actuating the stem of the'cylindrical member 15, inwardly, the coil spring 22 serving to restore the stem to its outer limit of movement. a hand-grip 31.

The sliding movements of the plunger 31 ar'e adapted to be controlled by a detent mechanism, represented, as a whole, by the numeral 44, but not described herein, as such details are fully set forth in my application filed of even date herewith.

The plunger is adapted to be pushed inwardly whereby to operate the various levers and links, and accomplish the release of a drinking cup, and the operation of the liquid measuring cylinder, to receive its charge of lliquid from the tank. Releasing the plunger normal outward position, by meansFo the spring 22, so as to register its openings 18 with the spout, and discharge its liquid into the cup placed below the spout.

Mounted beneath the cup delivering mechanism is a chamber 54, theiifront portion of which is open,/as/seen in the drawing, and formed inthe/bottom wall of this chamber is a cup VVreceiving recess 55. In oneend of the upper wall of the chamber there is secured a downwardly tapering spout 56, to the upper end of which is properly secured a downwardly tapering spout 57, forming a part of the .cup mechanism. Leading downwardly, and laterally from the lower end of the spout 56, is a chute 58, in which the individual paper cups slide, to be seated, in an upright position in the recess 55. The lower end of the chute 58 is secured to the ladjacent side of the recess 55, whereby to On the outer end of the plunger is wall 59, against which the cup engages, and

the recess 55, directly beneath the liquid' spout 12, and then the cylinder 15 moved inwardly to receive `a charge of liquid from the tank and outwardly to deliver its charge into the waiting cup. In the, bottom of the recess 55 there is secured a drain pipe 60, to discharge any waste accumulating in the recess, such waste being arranged to be caught by any might be placed therebeneath.

In the center of the upper wall of the chamber there is formed an opening 61 through which the end of the spout 12 projects, to discharge the liquid directly into the cup.

What is claimed is:

1. In a liquid dispensing machine, the combination with a measurin valve and a cup dispensing mechanism, o a support, a plunger slidable on the support, links operatively connected with the plunger, connections lbetween one of the links and the measuring valve, and connections between the other link land the cup dispensingmechamsm.

2. In a liquid dispensing device, the combination with a measuring valve and a cup dispensing mechanism, of a guide vdisposed suitable receptacle which adjacent the valve and cup mechanism, a Y permits the cylinder 15 to be restored to /plungerlmeunted/onthe"`guide, a pin carried by the plunger and extending, above and below the guide, a link connected with the upper end of the pin and with the cup mechanism, and a link connected with the lower end of the pin and with the measuring valve.

3. In a llquid dispensing device, the combination with a measuring valve and a cup dispensing mechanism, of a support adjacent the valve and having a longitudinal slot therein, a plunger slidable in the support, a vertical pin carried by the plunger extending below the plunger and upwardly through said slot, a link pivotally connected to the upper end of the pin above the support and operatively connected with the cup dispensing mechanism, and a link pivotally connected with the lower end of the pin and operatively connected with thc measuring valve.

In testimony whereof, I aix my signature.
