. ATTORNEY Patented Sept. 23, 1930 UNITED STATES PATENT OFFICE EDGAR A. GALLESON, OF MERRICK, NEW YORK, ASSIGNOR '1O DRINKOLETTE SALES CORPORATION, OF NEW YORK, N. Y., ACORPORATION OF NEW YORK DRINK-DISPENSING APPARATUS Application filed June 11,1929. Serial No. 370,109.

This invention relates to dispensing apparatus and especially apparatus for dispensing liquids, as beverages. According to the in apredetermined quantity (as a cupful) at a single dispensing operation, whereby the mixture will be fresh when delivered and the entire apparatus may be made quite compact.

One object of the invention is to provide for the dispensing in such manner that the mixing of the two liquids shall occur as-the result of the operation of dispensing; also that such mixing shall be as thorough as possible. Another object is to insure that equal quantities shall be dispensed on successive operations, and that where, as usual, the flavor ing liquid is a syrup the water shall act to cleanse the device by which such syrup is measured. Another object is to provide for the dispensing of a cup with each quantity of liquid, or drink, dispensed, the cup being automatically placed in proper position to receive the drink; in the preferred form the dispensin of the cup and then of the liquid is effecte by operation of means common to both and single in character. Another object is to improve the means by which the dis pensing of the cups is effected.

. Fig. 9 is a vertical sectional view of the part of the apparatus embodying the coincontrolled operating mechanism, which .appears in elevation; and

closed in some suitable way. In this wall, at

about its middle, is a niche structure 6 and within the latter is a cup-shaped cup-receiver 7 provision is made (as will appear) for admission of the cups and also of the beverage to this niche structure, and it may have a small front glazed closure 8 normally held closed, as by a spring (not shown), and free- 1y openable by the customer. Door 5 may also have an opening 9 through which the customers may deposit the waste cups in the bin 3. Liquid dispensing.1n the chamber 4 is a Water tank 10 which is L-shaped in plan (Fig. 5). This is preferably jacketed in heat-insulating material 11, and it may contain a cooling coil 12 adapted to form part of a system for keeping the water. in the tank cool, as by being suitably connected with the refrigerating unit 2. In this tank 10 is a syrup tank 13. The water tank 10 may stantially constant is afforded by an ordinary and the float 16 controlling the valve, closing it on rising and opening it on falling. I (17 is simply a partition to isolate the float from agitation of the water in tank 10 incident to the movement of certain parts, as will appear). The syrup tank receives its supply from the syrup reservoir 18 (Fig. 3) which is placed above the tank 10 and has a discharge tube 19 reaching down into the body of liquid (syrup) in the tank 13; the reservoir being closed to the atmosphere a hying here also its fulcrum or pivot and penetrating a suitable gland or equivalent liquid sealing means 23 in the front walls (here face to face) of the tanks 10 and 13 (Figs. 5 and 6). When the dippers are depressed until submerged and then elevated the discharge of the water takes place via the syrup dipper, so that it does not become fouled with more or less dried syrup.

The discharge of the liquids via tube 21 is into the nozzle 24 which, as shown in Fig. 8, debouches through ahole in the top of the niche structure 6 into the cup deposited therein in receiver 7. The nozzle has a chamber 24 provided with a bottom outlet 24 and with a dam 24. Without this special construction there may be a tendency for the liquids to be delivered to the cup so that there would be a quantum of pure syrup at the bottom of the cup; but with it the flow of pure syrup proceeds more slowly than it otherwise would (through outlet 24") while the body of liquid consisting at first of more or less diluted syrup and ultimately of pure 'water sweeps over the syrup in chamber 24 and over the dam, with the result that the thick syrup, liquid is mixed with water when it reaches the cup and the final flow of clear water washes out the passage entirely.

The two dippers are connected to descend and rise together thus: A bifurcated plunger is formed by thehead 25 and two rods'26 and 27 depending therefrom, these sliding in the fixed guide 28 (Fig. 3) and one being fixed to dipper 20 and the other having a pivotal connection 27 a with one link 21 pivoted to dipper 21 at 21. tional resistance of control may be applied to the plunger by the brake-device 29 held against one rod by a spring 30 subject to an adjusting screw 31 tapped into said guide. The connection is in the example actually such, as indicated, that the dippers both rise and fall by movement of plungers 26 and 27 but due to the link 21, connected as shown, the syrup dipper 21 reaches the discharging position sufficiently ahead of water dipper 20 so as to insure. against water backing up into the syrup supply tank in case the manually operated upstroke of plungers 26 and 27 should not be entirely completed.

other.

Variable fric- 1, as to brackets 32-on its door 5, is an aunular hopper.33 in which is journaled the vertical shaft 34 having a head 35 seated on the hopper and equipped with several upstanding cylindrical cup-holders 36; below the hopper the shaft has a ratchet-wheel 37 The hopper has a chute 38 debouching downwardly into niche structure 6 so as to deliver each cup to the receiver 7. .The cups A are'of the type having exterior flanges AT at their mouths and their form is such that when arranged in stacks, as shown, their flanges are a trifle spaced from each The rotary turret comprising the shaft, its head and the ratchet-wheel is turned step by step, each stack of on s sliding on the bottom of the annular iopper' except in the region including the downtake 32 of the chute, where the flange of the next from the bottom cup overrides two guides 39 on the hopper and that cup and all above it then slide along on these flanges until the chute entrance or downtake is passed, whereupon what is thus left of the ill) stack again slides on the bottom of the hopper. The lowest cup (i. e., the one below the one which overrode the guides), when it reaches the chute downtake, of course falls therethrough into the receiver 7. Preferably I the bottom of the hopper 33 has a step-down 33 just following the point where each cuppressed pawl 40. Fulcrumed on the shaft 34 is a cup-feed-control member in the form of a pawl-lever 41 carrying a spring-pressed pawl 42 engaged with the ratchet-wheel. said member being adapted on each return or idle stroke to disengage the pawl 40 from the wheel. (Fig. 4.) Thus the cup-conveyor is adapted to be rotated step by step.

Urea-controlled operating means.-In a casing 43 (Figs. 9 and 10) on the door 5 is a sleeve 44 having arms 44 and 44". Arm 44 has pivoted thereto a link 45 which slides in a. guide 46 pivoted in a bracket 47 attached to door 5, and this link has an arm 48 which engages in a horizontal slot 25 of the head 25 of the before-mentioned dipper actuating plunger. Arm 44 is connected by a link 49 with the pawl-lever 41. Therefore each time the sleeve 44 is turned to the right it against backward movement by the spring I dippers are fully elevated and the raises the'plunger and the two dip ers, thus reducing the liquid delivery into t e placed ward stroke is eflected through a coin'which.

interlocks the sleeve and barrel together and which is entered at a coin-slot 52 in the housing 5 and passes through casing 43 into slots 53 in the sleeve and barrel provided all these slots register as in Fig. 10, which shows the parts in the positions they occupy when thle aw lever 41 fully retracted; atthe end 0 this stroke the coin falls through a chute 54 into,

a. coin-box 55. The anti-clockwise or return stroke of the sleeve is effected by the knob-spindle through an arm 56 on the same which abuts the arm 44 of the sleeve when the slotsof the spindle-barrel and sleeve are alined. Of course if-no coin is resent, movement of the knob-s indle is a rtive. It may be desired to stir the syrup in the reservoir 18 to keep it throu hout of uniform consistency. Wherefore 5% is a propeller journaled therein and havin a pinion 58 with which engages a rack 59 aving a stem 60 which reaches down-through tube 19 and then up exterior of reservoir 18, being connected by arm 61 withthe head 25 of the plunger.- Each time the latter descends'and rises the propeller is rotated back and forth. Having thus fully described my invention what I claim is:

- 1. The combination of containers for the liquids to be dispensed, and mechanism to dis-'.

pense the liquids therefrom including di pers immersible 1n and withdrawable from t e respective liquids and means to immerse them into receiving relation to and withdraw them' from the liquids, one of said dippers having means to discharge its liquid content into the other on such withdrawaland'the latter forming the discharge 'of said dispensing mechanism.

2. The combination of containers for the liquids to be dispensed,- and mechanism to dippers immersible in and withdrawable from the respective liquids and means to immerse them into receiving relation to and withdraw them from the liquids, said dip ers being connected to erform together t eir immersing and with rawing movements and one having means to'discharge its liquid content into the other on such withdrawal and the latter forming the discharge of said dispensin mechanism,

4.' e combination of containers for the liquids to be dispensed, dippers immersible in and withdrawable from the respective liquids and one of said dippers having means to discharge its liquid content into the other of said dippers on such withdrawal and the latter forming the discharge of said dispensing means, and a back-and-forth-movas ble plunger operatively connecting said dippers for movement substantially as a unit.

5. The combination of containers for the liquids to' be dispensed, a dipper pivoted to move down into and then from one 1i uid, a dipper movable substantially rectillnealg' down into and then from the other liqui means for discharging from one dipper to the other and a back-and-forth-movable plunger opera'tively connecting the two di pers.

' 6. A liquid delivery device having its dis-- thicker liquid in the chamber and over the dam.

7. In combination,'a supporting structure adapted to'receive a cup in osition-for filling, a back-and-forth-movab e means carried thereby and adapted to receive a liquid on movement in one direction and deliver it to the thus-receivedcup on movement'in the other direction, a cup-feed-control member movable in said structure and having a feed 7 stroke and a' return stroke, and means connecting the first means and said member, to cause the liquid-receiving movement of the former and the feed stroke of the latter to occur substantially simultaneously and. the liquid-delivery movement of the former and return stroke of the latter to occur also substantially simultaneously.

8. 'In combination, a supporting structure adapted to receive a cup in position for filling, a liquid container, means carried thereby to dis ense liquid into the thus-received cup inclu ing a dipper immersible into and withdrawable from the liquid in said container, a .cup-feed-control member. movable in said structure and having a feed stroke and a re turn stroke, and 'means, connecting said dipper and member, to cause'the immersing movement of the former and the feed stroke of. the latter to occur substantially simul taneously and the withdrawing movement of the former and return stroke of the latter to occur also substantially simultaneously.
