Referring specifically to the drawings, the invention in its illustrated embodiment is composed of a relatively tall and narrow rectangular cabinet I5 of metal, providing a base it, back wall ll, side walls I8 and a front door i9 mounted on a vertical hinge 20, and extending from the base to the open top of the cabinetwhich is closed by a hinged cover 2l, the door l9 and the cover 2| being locked together by a single lock 22.
Supported on the base 16 beneath a horizontal taken on position on the turntable 33 between two adjacent walls 38 thereof.
For an angular distance of 240 degrees, an arcuate guard wall 45 of a height corresponding to that of the walls 38, confines cups on the turntable against lateral displacement therefrom,
' with theremaining 120 degrees at the front of partition 23 is a removable receptacle 24of relatively large capacity in which is stored under pressure a carbonated beverage to be dispensed. A discharge pipe 25 extends vertically downward through the neck of the receptacle to a point close to the bottom of the latter, and is controlled by a regulating valve 26 in the neck of the receptacle as shown in Figure 2. The original pressure in the receptacle 24 may be as high as 240 #/sq. in., and, in any event, must be sufficiently high to elevate the entire contents of the receptacle as required, to an insulated dispensing tank I 21 supported in the upper portion of the. cabinet [5 as shown in Figure 2.
The beverage in the dispensing tank 21 is automatically maintained in acooled state suitable for preservation and palatable drinking, by a conventional type of thermostatically controlled refrigerating unit 28 whose refrigerating coils 29 are horizontally disposed in the tank 21 and are included in the usual fluid circuit of the unit as is well known in the art. 7
The bottom of the dispensing tank 21 is provided with an outlet 3lt connected to a valve which may be in the form of a faucet 3! whose spout 32 is disposed above a cup carrier designated,
generally at C and including a turntable 33 fixed to a vertical shaft 34 journaled in a bearing plate 35 resting upon and fixed to spaced, upstanding lugs 36 on a base plate 31 secured to the partition 23, all to mount the carrier C for rotation about a vertical axis. The carrier C also includes a plurality of vertical partition walls 38 of which three are shown in the present instance equally spaced 120 degrees the turntable through openings 5| in the latter.

that by hand or otherwise, cup a has been placed on'the =turn'tab1e 3-3 in the compartment thereof at th'e'c'up=fil1ing station SI as shown in Fig- "ure 3. Let it also be'assumed thata-receptacle '24 "containing "the beverage to be dispensed, is
connected to "the dispensing tank 21, and that the float I29 has co acted with the levers lal to 'clo'se-the valve I28, thus predetermining the level at which the liquid will stand in the l dislpensing'tank. It Will-be noted that the-loading of the spring I 23 is such that it will remain clos edto maint'am a maximum pressure-of about 4#/sq. in. in the b'everage chamber H9, or a pressure at least sufficient to maintainca-rbon- 'ation of the liquid in "such chambe -and'that the valve 122 will open 'in opposition to the "spring I23 should the. pressure in the beverage chamber exceed this predetermined pressure-so as to vent the'excess pressure -into the chamber I20, whereby'to' insure thata uhifo'rmzpres- "sure will be constantly maintained tin the bevera'ge chamber irrespective of the r'gradual -1ow- -ering of the superior high lpressure used all to :cbviatepossible-jamming-of the ma- ;7 ;provided-in the'receptacle originally yber [Iillxbythe loading-of the'spring of the check valve I25, to insure that carbonation of -;the beverage in the chamber I I9 will be maintained with but a slightly lowered pressure which ,will have only a negligible efiect on the quantityof beverage dispensed from thechamber II9 during the cup filling operation. 7
Upon the deposit of a coin into the slot 60,
current is supplied to the motor 65 to rotate Zthe shaft GI in a counterclockwise direction as viewed in Figures 2 and 4, through exactly one *r'evolution; under the control of the mechanism '('not ts'hown) fully disclosed in my Patent No.
2,370,276; 'During the initial portion of this one revolution of the shaft BI, the cam II co-acts with the roller I2, rocker arm I3 and link I8, -to open the faucet 3|, during which the cam I9 actuates the cup release lever 42 of the cup dispenser 4| to drop a cup in the compartment of the'turntable 33 at the cup loading station S,
as indicated at b in Figure 3.
As the cam 'I'I recedes, from the roller I2, the spring I6 co-ac'ts with the arm I3 and link T8 to close thetfaucet 3i, it being understood that the timingof the mechanism is such that the faucet 3| will be open only so long as to dispense theexact amount of beverage from the uniformly pressured supply in the chamber II9, to fill the cup 11 to a predetermined level. As beverage discharges from the chamber I I9 with the attending lowering of the float I29, the valve I28 will open sufiiciently to replenish the quantity of beverage dispensed, so as to maintain the predetermined uniform level of beverage in the chamber II9.
operation.
In the unlocked position of the dog 91 as shown in Figure 9, the pawl 9| has just ridden over one of the pins I03 on the locking disk I00, and the bill I94 of the pawl is disposed to engage such pin as the return movement of the actuating, bar 86 to the left as viewed in this figure, is now initiated, so as to rotate the carrierC in the clockwise direction as viewed in Figures 3, and '7. The dog 91' is now freed of the pin IIJI so that the spring 99 will urge the lug 98 of the dog into engagement with the periphery of the locking disk N10, for reentry into the next succeeding one of the recesses 99 when 120 degrees of movement of the carrier has been completed to dispose the compartment of the car-v o rier containing thefilled cup or at the delivery station S2, for removal by the customer.
The rounded nose 94 of the cam 93 is engaged by the bill I94 of the pawl 9! so as to raise the latter against the action of the spring 92, clear of that pin I03 being driven by the pawl, thus operatively disconnecting the pawl from the carrier C, and sufficiently prior to completion of 120 degrees. of movement thereof for the inertia of the carrier to be compensated for, and relocking of the carrier by the dog 91 insured.
Should the cup 0. after use, be inadvertently or. carelessly replaced on the carrier C instead of being dropped into thewaste container 53 through the ripening it. at eih rwise diseases of, the stopg|96 and the projection I09 on the vcarrier wall 38 immediately following this cup,
will co-act by a circumferential wiping action upon the cup,.to roll same from the carrier during the next operation of the machine, so as to positively prevent jammin or defective operation of the machine by such cup.
From the foregoing description, it Will be manifest that during each cycle of operation of the machine, an empty cup will be deposited on thecarrier C, concurrently with filling of a previously deposited cup with a predetermined quantity of liquid or other fluid material from a supply thereof,all within'the sanitary interior of the machine, and that following the filling operation, the normally locked carrier will be unlocked for a sufficient interval for the filled cup to be delivered to a delivery station exteriorly of the machine for removal from the carrier by the customer.
