and then mixed together in a container, theb tendencyof such liquids is to foam; and the amount of foam in the successive drinks d1s pensed, varies according to the gas pressure 1n the efervescing liquid used.

` An object of this invention 1s to provide a machine of this character that will dispensev to a liquid container a requisite amount of liquids with due 're ard to the variations of4 pressure under which such liquids ma be delivered, so that each charge of liqui delivered to the container, will, without exception, approximately fill the container to a predetermined level.

Another object is to make provision whereby the liquid delivery mechanism may be adjusted so that the liquid delivered to the Acontainer will invariably be in such quantity as to practically ll the cup without overflowing.

A feature of this invention is a construction and arran ement of measuring mechanism which will be governed by gas pressure from the carbonated water to deliver a less amount of such water under high gas pressure than under lower gas pressures and 5 yet fill the containers when the water is not so highly charged With gas.

With this device Athe amount of carbonated water delivered will be gradually increased as the gas pressure therein lowers so that the combined liquid, syrup and foam will at each operation just ill the container.

I have discovered that it is practicable to combine the forces of gravity, atmospheric pressure and the pressure of gas from the effervescent liquid to accurately measure and deliver a predetermined charge of syrup, and

to employ the buoyant force of the e'erves- I,

cent liquid in conjunction with the abovementioned forces to measure the elfervescent liquid and discharge it with the syrup, into a cup.-

I havediscovered that by filling with syrup a chamber that has an outlet at the top, and applying gas from an efervescing liquid while the eiervescing lliquid is being discharged from its container into a measuring chamber, the syrup may be Jforced out of the syrup chamber in exact quantity and that the etiervescing liquid discharged into the measuring chamber therefor, may be so measured that the liquids and foam will when delivered to a cup, always practically iillffthe cup; there bein a larger discharge of the liquid, and less 0am, when pressure of gas in the eil'ervescing liquid is low, than .when it is high.

An object of the invention is to serve full cups without overflow irrespective of the variationsof gas .pressure in the efervescing liquid.

In this invention I provide a pressure chamber having at the top a vent, and at the bottom a valved outlet, and connect the chamber through an inlet valve with a pres! sure tankI containing carbonated water or other eifervescent liquid under pressure; and I provide a ioat in the chamber to close Vthe vent when the eiervescent liquid from the tank fills the chamber to a predetermined level, and also provide means adapted and arranged to be operated by the pressure in the pressure chamber when the vent and outlets are closed, to cause the inlet valve of said chamber to be closed andthe outlet valve to be o ened; and I also provide a pump operable y the -pressure in the pressure chamber to supply syrup or other quiescent liquid for mixture with the eervescent liquid when the same is discharged from the chamber.

In this invention I provide novel means whereby the vending operation of the machine is started manually and the force thus applied gives tension tc spring means that continues the operation automatically and returns the automatically operated parts to initial or normal'position.

An object of the invention is to provide a novel vendin machine of this character in v which a sing ek manual operation, will first place a cup in position to be filled and made available for use, and second, will properly measure a syrup and eervescent llquid to mix a drink and deliver such syrup and liquid to the available cup without overiiowing the cup.

I have rovided a cup and beverage machine whic may be used as a semi-automatic vendin machine for saving the time of softdrink ispensing clerks.

A -feature of this invention is that at each operation of the machine, an amount of liquid under pressure is dis ensed into a cup that is-made accessible to t e operator and 1s uniformlyv filled, responsive to the variations of gas pressure in the liquid delivered.

The invention .is broadly new, basic and pioneer in that the machine is only started mto operation b a redetermined movement of a hand cran wliich'may be at once returned to initial position while the drink is ybeing delivered and mixed; and the crankl is then free to be operated, or left at rest.

In this invention provision is made whereby the crank may be freely oscillated after any operation of the machine, without again operating the machine, unless connection between the crank and the o erating mechanism is made by an inserted) member which is displaced from its operative position when the crank passes a certain position, and such inserted member is then displaced positively by r1spring actuated means.

e connecting element may bea coin and a further feature consists in means to bar admission of a coin, except when the hand crank is in initial or normal non-operative position.

An object is to kee the machine from be comin untidy throug accumulations of drip from t e discharged drink. l

An object is to positively discharge the coin into the receptacle therefor when it has served its purpose of forming a suitable connectio-n to set the vending machine in motion.

feature of the invention is the employment of the ,coin to tension a spring the force of which serves to knock the coin out of its carrier before the vending mechanism delivers a cup or-a drink.

Another object is to retain the coin in ope" ative position untiltlie vending mechanism has been started into operation.

Objects are to avoid dependance upon the .weight or the impact of either liquid er upon any lever or levers or other mechanism actuated hy such weight or impact to determine any operation of the machine; and to utilize a ioat valve lifted by the eii'ervescent liquid charge to close the gas vent; and tothen utilize the pressure in the pressure chamber to discharge the syrup and to release the valve that controls the flow of efervescent liquid u from the drum or tank to the pressure cham ber and to open a valve to permit the flow of such efervescent liquid from the pressure chamber; and in carrying out the invention I provide a syrup fountain so connected with the syrup measuring chamber as to normall keep such chamber nearly full without bac pressure, so that the work of discharging the char e is minimized, and leakage is avoided.

Ot er objects, advantages and features of invention mayappear from the accompanying drawings, the sub'oined detailed description and the appende claims.

The invention includes the cup and drink vending machine and the parts and combinations o described, and claimed.

It is intended that in common use the machine a will preferably be housed in a cabinet K, not necessary to be shown herein, and that only part of the front of the machine will be exposed to view, while the remainder of the machine is covered by the cabinet to revent tampering with or injury to the mac ne proper.

For the purposes of this description it will be assumed that the drink to be vended shall consist of two components.; viz., a syrup spaced apart and secured to said base and top by cap screws 3a, 3b.

The base casting 1 is provided with a recess 4, which is open at the front side and has a horizontal U-shaped forwardly open lip 4a on which the cup in which the drink is to be vended is hung to receive the drink.

A cup 5 and spout 5 to take care of any drip, and a chute 5 through which to drop the used cups, lead from the frame 1.

to suitable receptacles not shown.

The casting 1 is also formed with a vertical passage 6 opening down to the recess 4, and through which the cups are delivered one at a time from a magazine above tothe lip 4a, by cup dispensing means, when the machine is operated to vend the drink.

The manually operated actuating mechanism comprises a hand crank 7 fixed to a horizontal shaft 8 that is journalled in a rib 1a at one side of the base castipg 1 and projects from the rear facevthereof, and that is there provided with a coin carrier 9 rigidly fixedv to the crank shaft 8 by a pin 8 and -to a bearing 10 that extends to a rib 11 of the frame.

12 is a coin slot open to the front of the frame and of just the cross section to receive and conduct a coin of the denomination required to pay for one of the drinks to be vended.

The coin carrier 9 is preferably U-shaped and the open space 9 between the limbs of the U is of less width than the coin slot '12.

-In the inside faces of the limbs of the U,

ooves 12 are cut to continue the coin slot ownward, and -these grooves are. adapted at their lower ends to unitedly form a coin seat 9a to seat a coin 13 to bridge 'the open space between the limbs ofthe U to bear against and operate a lug 14 and retract a tappet 14 when the crank 7 is turned for the purpose of operatingthe ven 1.ing mecha- The lug 14 and tappet 14 are fixed to, and extend on opposite sides of, a transmittin shaft 15 that is journalled in both limbs o the carrier 9, and also in the bearing 10 and in the rib 11.

A coil spring S is arranged to yieldingly hold the coin carrier against the outside of the frame member 1 `in osition to receive from the coin slot 12 a com 13 to bri e the ace 9 and operate the lug 14 to turn the s aft 15, to which the lug 14 is fixed by pin 15.

Said slot l2 is formed in the frame member 1, and extends from the front face of said member to deliver a coin into the coin seat 9a in the coin carrier when said carrier and other parts of the machine are in coin receivin position. f

en there is no coin in the coin seat 9a the crank 7 ymay be oscillated almost throughout one revolution and the carrier stops against the frame at each end of its arc of travel.

The spring S returns the carrier with considerable force to its sto on the outside of the frame, and there is likely to be more or less batterin of the frame or the carrier, thus misalining the seat with reference to the slot, and to correct this diiculty adjust-able stop lugs 16 in the form of screws are threaded through the carrier to engage the frame so that when the contacting surfaces become battered the coin seat may be again alined with the slot by screwing the stops further through the carrier, thus to cause the carrier to stop in position to receive the coin from the coin slot.

When the coin slot 12 is unobstructed and a coin of required size is dropped thereinto such coin passes down into the coin seat 9a and then upon oscillation of the crank, the coin engages and swings the lug 14 around, thus transmitting motion to the shaft 15, thereby revolving a bevel gear 17 which is fixed on the inner end of the shaft 15.

The bevel gear 17, meshes with a gear 18 fixed to a vertical shaft 19, which is journalled at the rear of the base member 1 in ears 20, projecting from said member, and is connected to operate the cup delivering mechanism detailed in Figs. 16, 17, 18, 21 and 22.

A gear 21 meshes with the gear 18 and is fixed to one section 22 of a horizontal shaft which is formed of two torsionally connected sections 22, 22. A revolvable member in the form of a cam wheel 23 is fixed to the section 22 and is arranged and connected to close the pressure liquid outlet valve'and open the pressure liquid inlet valve and to complete the operation of the cup delivering mechanisms.

The lug and tappet 14 and 14', vertical shaft 19, the cup delivering means, and the cam wheel 23 are thus connected for coordinate operation.

A master spring preferably formed of two coils as at 27, eccentrically connected by crank pin 27 to the revolvable member 23 holds the cam wheel 23 normally in a predetermined position, andthe operation of the lu 14 by the coin is a ainst the resistance of sai master sprin an such resistance affords a friction on t e vcoin that tends to hold the coin in the coin seat while operatino` the lug. The coin enters the coin seat from a ove, and when the coin carrier is revolved suiciently to invert the coin seat, the coin would drop out if it were not for the friction caused by the resistance of spring 27, which is given tension by revolutlon of the cam 23' and when the cam crank pin 27, by which the master spring 27 is ecc'entrically connected to the cam 23, comes'to dead-center asthe spring swings across the axis of the cam, the resistance of the master spring to the advance of the lu under the pressure of the coin carried by t e coin carrier is so reduced that the friction on the coin would be insuiiicient to uphold the coin, andthe coin would drop out of vthe inverted coin carrier, thus leaving no connection between the coin carrier and the cam 23, so that the operation of the machine would notbe carried on.

To overcome this diiiiculty, the cam operating shaft is made in the two alined sections 22 and 22 and these sections are connected to each other by a torsion coupling comprising an intermediate spring 22a the ends of which are fixed to the sections 22, 22',

resgiectively, by means of sleeves 2225 and 22o.

aid intermediate spring 22a is of such strength that when it i's put under tension by the resistance of spring 27 as it approaches .the dead center position, the reaction of such spring against the lug is sufficient not only to frictionally hold the coin until the dead center position is reached, but also to suddenly thrust the cam wheel onward after the spring passes the dead center; and the moment the spring 27'passes such dead center, it is operative to instantly turn the revolvable member or cam 23 to normal or initial position where it comes to rest and is held in such initial position by the tension ofthe spring27.

The intermediate spring 22a is so adjusted by means of said screw d in the collar e on the coupling sleeve 226 which is fixed by pin f to the shaft member 22 that the tension of spring 22a will be suiiicient to accomplish the results above set forth. The cam 23 when returned to normal position also returns the gears 21, 18 and 17 to-a pre-determined nor- 23 by spring 27 revolves shaft 15 and moves the tap et 14 against the coin to positively knock t e released coin ont of the coin seat in the event the coin has not previously fallen therefrom by gravity.

The shaft member 22 is journalled at one l end in a block 24, and the other member 22 is j ournalled in a bearing 25 depending from a casting 26 secured to the bottom ofthe casting 2.

The spring 27 secured to the eccentric cam pin 27 on the cam wheel 23 and to the frame, yieldingly holds said wheel 23 and its connections at the rest position, and it not only operates the tappet to eject the coin, but also operates means to dispense cups to receive the drinks.

The crank is only oscillatable and stops s'hort of acomplete revolution, as indicated in Figs. 1 and 19; and the gears 17, 18, 21 are so arranged that the cam wheel 23 can be turned to a point somewhat more than 180 from rest'by operation of said crank and before the crank reaches the limit of its movement the cam wheel and the tappet are automatically caused by reaction of spring 27 to complete a full revolution and return to rest and to perfect thevvendi'ng of the cup and drink.

Thecup dispensing device comprises a magazine 28 mounted on and stationary to the casting 1 and havin a circular cup-way 29 above and axially ai ed with the passage 6, and having a amfered internal flange'30 below which thin'mutilatedworm rimmed or perilpsherally threaded revolvable cup feeding dis 31, are arranged to support a stack ofvnested cups C in the magazine. Said disks are mounted on shafts 32 and 32 and are arranged to be revolved relative to` the magazine. They are arranged with their `spiral peripheries projecting into the cupway 29 to unitedly support the rim fiange of the lowermost cup at one part of the revolution and the spiral peripheral grooves in. said disks are adapted to receive the rim flange of the lowermost cup and move such rim down and thus cause the cup to drop into the vertical passage V6 when the disks are turned tothe appropriate-position for supportin the next cup rim.

Pre erably there are three of such vdisks symmetrically disposed, as shown, andin fixed relation to respective operating gears.

A gear 33 and its disk 31 are in fixed relation to shaft 32, andthe gear 33 meshes with an annular gear 34, which is journalled on a depending collar. 35 on the fiange 30 and is initially revolved by power applied through the hand crank 7. Disk gears 36 and 37 are fixed to the other disks and mesh with the ring or annular gear 34 to be revolved thereby; so that all three disks revolve alike when the shaft 32 is revolved.

As shown in Fig. 12, the cups C have flanged rims b' and are nested one within another in the chamfered fiange 30, with the fiange b of the bottom cup resting on the disks 31. As these disks rotate, their threaded peripheries receive and engage the flange b of the bottom cup and move it down until the cup drops through the passage and rests on the lip 4a in the recess 4, ready to receive liquid from the outlet 38 as will be Ahei'einthrough a train of gears comprising gear 39- fixed to shaft 19, and meshed with gear 40 that is fixed to shaft 41, to` which 1s fixed gear 42 that is meshed with gear 43, fixed to shaft 32 which turns gear 33 that revolves annular gear 34, by which the disk gears 36 and 37 are revolved. When the crank is turned,-With coin in place, the shafts 19 and 41 will be turned, and also the gear 43 and thus revolve the annular gear 34, and the disks 31 will be simultaneously rotated to dispense a cup. The cam wheel 23 on shaft member 22 is turned through an are to stretch the spring 27 which instantlycompletes the revolution of the shaft 22, when the spring passes dead center.

A counter 44 is operatively connected to one ofthe shafts 32'; and'records the number of cu s dispensed by the machine, and therefore t e number of times it is operated.

- Means are provided to prevent the insertion of a coin when the supply of cups is exhausted, and such means comprise a spring actuated coin stop operatin arm 45 that is pivoted intermediate its en s at 45 and is provided at one end with a part, as finger 46 constructed and arranged to be pressed against the rim of a disk supported cup by aspring 47 that tends to insert a stop 48 mounted at Vthe other end of arm 45 into the coin slot 12 eta point close to the front 'of the frame so that when the stop is in the draw t e finger from lthe cups during the operation of dispensing a cup, and this is effected'by a pin 49 normally retracted by a spring 51, and adapted to be inserted into slot 12 through a hole, and into engagement with the stop 48 to push said stop back to oscillate arm 45 and retract the finger 46 from the cup; a lever 52 fulcrumed to the frame at 53 is voperable by a cam 54 fixed to the crank-shaft 8, to push the pin 50 into the finger retracting position after a coin has been dropped into the coin carrier, and directly after the crank 7 .has been moved to turn the coin carrier and the cup dispensing device` When the pin 50 has been moved into engagement with the stop 48 it has kpassed transversely through the coin slot 12 so that another coin cannot be inserted in said slot and also provides a means for requiring the handle 7 to be in initial position when a coin is inserted and thereby assures correct positioning of the coin carrier relative to the. slot 12 when the coin is inserted.

The cam 54 extends around the axis of the shaft 8 sufficiently to hold the. lever 52 and pin in finger retracting position throughout all except a limite initial are of the crank oscillation, so that While the cup feeding disks 31 are lowering the cup, the finger 46 is held retracted from the path of the projecting cup rini, but when the crank is returned to its initial position shown in solid lines in Figs. 1 and 14, the-spring 4'? again presses the finger 46 against a cup, the stop 48 is Withdrawn from the coin slot soloug as cups are in the cup receptaclee and n" the cam 54 is withdrawn from the lever the spring 51 withdraws the p in the coin slot 12 leaving said slot 'fito -or the insertion of another coin.

The drink measuring and dispensing mechanism is contained in and supported by a hollow casting 55 having a coverpiate 56s and which is secured to the top member 2 of the machine frame, and the. top of which forms a bottom for said hollow casting.

A fountain or tray 57 is provided on the casting 2,-and a jar 58 is inverted thereon, and may contain a.liquid syrup, iavoring or similar substance to be mixed with another liquid or li uids. A tube 59 leads from the tray 57, an is secured to the cast-ing by screws threaded into flanges 60, and seid f opens into an intake vf 61 opens into a measuring chamber L inder 62 through e. passage at t,... o of said chamber and cylinder and the it. cylinder communicates with an cutie., chainber 64 through a duct 65 and port 65" adje cent the top of said outlet chamber has an outlet at its bottom through lioie 66 that alnes with a tube 67 formed in the caso ing 26. A vent 68 at the top of chamber 64 admits air to prevent syphoning of liquid from the jar 58.

A rod 69 having a valve 70 thereon extends through the castings 26 and 2, and has at its lower end an anti-friction roller 69 that rests on the cam wheel 23 to ride the cam and be raised thereby while the wheel is rotated part way or during the spring tensioning portion of its revolution; and to cause the valve 70 to temporarily close thepassage 71, which leads from the bottom of a pressure and float chamber 72 into the expansion chamber '71 in the casting 26. Near the top of vits upward stroke and after the valve 70 is seated and the cam 28 is moving during the spring retracting portion of its revolution, the valve4 stem 69 lifts a valve stem 78, and unseats a pressure liquid inlet valve 74, and permits the pressure'luid to low from the tting 75 through the cage 76 and slot 76 into the chamber 72, While the outlet 71 is closed by valve 7 O.

A pressure tank or drum 78 containing eiiervescent pressure liquid such-as carbonated Water, is connected to the litting by a suitable pipe 79, so that when valve 74 is opened the chamber 72 is supplied with. a charge of pressure liquid.

' A spring 77 around the stem 73 tends to normally seat the valve 74. The outlet passage 71 from the pressure chamber 72 must remain closed while the pressure duid is filling said chamber and until the liquid lifts the float 80 therein and a stem 81 fixed thereto until said float closes a vent hole 81 in the :over 56 and until sufficient pressure is obtained in the pressure chamber to operate the syrup dispensing mechanism as will be more fully hereinafter described. Said stem 81 extends through the hole 81 in the cover and is guided by said cover and by a spider 82 in the bottoni of chamber 72. The float 8G has a slight movement to cause a valve 83 on the upper end of the lioat to close and open the vent at the hole 81', which communi,- Cates with diverging vent holes to allovv free escape of gas until the float 8G and the vent valve 83 are lifted by the pressure liquid to close the vent when the pressure chamber.

72 has received the required charge of eifervescent liquid.

Jam-n uts85 screwed onto the float stem 81 are adapted to normally rest on cover 56 and to support the fioat close to the top of the chamber 72, so that only a slight lifting of the iioat is required to cause the valve 83 to close the vent holes 84.

t yThe chambered body formed ci' the casting 55 is provided with a` bore 86 threaded receive a nipple 86 and adapted receive fie valve seat bushing 87 having at its upper end the cage 76, and provided with out- "os 87; and the valve stem 73 extends down through the cage 76 and bushing 87, which is provided with a gland 87 that is shouldered Ill) ' spout 38 wit sucient velocity to .shoot over. into the cup C, but the spout terminates suflil to receive the thrust of the spring 77, which operates between the shoulder of the gland 87 and the collar 73 fixed to the valve stem 73.

When the valve 74 is opened, the efervescing liquid from the drum 78 flows through the slot 76 into the float chamber 72 until shortly after the float 80 is raised suiliciently to cause the valve 83 to close the vent holes 84; and the pressure in the pressure chamber is communicated through a port 88, Figs. 24 and 25, into a cylinder bore 89, that is axially aligned with and is of less diameter than the pump cylinder or syrup chamber 62.

A cylinder headv90 atthe lower end of the bore 89 prevents the pressure in bore 89 from flowing into the syrup chamber 62 and a piston rod 91 extending through such cylinder head is provided below such head in the syrup chamber 62 with a syrup lifting head 92, which normally rests with its top below the top of the syrup inlet 63; and said head is submerged in syrup to the lever f of the fountain tray 57.

A pressure operated syrup pump-piston 93 is fixed-'to the rod 91`above the port 88 which opens into the bore 89, and a weight 91 is provided on piston rod 91 so that normally the syrup piston 92 is submerged in syrup; and as the pressure in the bore 89 becomes sufficient, it raises the piston 93, rod 91, weight 91', and piston 92; and the syrup above piston 92 in chamber 62 is thus forced out through duct 65 and port 65 and flows into chamber 64 and thence through hole 66, and tube 67 into the mixing tube or outlet 94, which extends from the expansion chamber 71 through a hole 95 in the rear of the casting 1, and delivers the uids through the outlet spout 38 into the cup previously delivered to and resting on the lip 4a.

The tube 94 is so steeply aslant that the liquids dischar ed thereinto will flow out of the ficiently behind the front rim of the drip cup to allowany drops which may drip from4 the end of the spout to fall into the drip cup and drain out through the drain 5 without smearing the lip 4a or the rim b of the cup.

The pressure liquidl outlet valve-lock releasing arm 96 fixed by pin 96 to the rod 91, is movable up and down by said rod 91 and is adapted to lift the outlet valve releasing rod 97, which is provided with an adjustable Steg) formed by nuts 97 on said rod 97.

id stop is normally spaced from the arm 96 as indicated in Fig. 2 so that when the power piston 93 is operated by pressure from the chamber 72, the arm 96 will operate with lost motion to lift the rod 97 at the end of a measuring stroke of the syrup pump piston 92. The rod 97 has a collar or tappet 97a which is adapted and arranged to lift the operating arm 9 8 of the rocking valve lock which is pivoted at 99 to the casting 2 adjacent the valve rod 69. Said rod 69 1s provided with a shoulder 100 under which the lock limb 98 of the valve lock may be moved by the spring 101 when the valve rod 69 is elevated by cam 23 to cause the valve 70 to close the outlet 71 as shown in Fig. 15. v

lVhen the arm 98 and its lock limb 98.are in Vloc-king position, as indicated in Fig. 15, the valve rod 69 and valve 70 are held to positively4 close the outlet 71; and when the arm 96 lifts the rod 97 and its tappet 97d to the position indicated in Fig. a, the valve rod 69 is free to be lowered.

The unlocking rod 97 is guided in the cover 56 and the guide '102 which is stationary to the casting 5 5, and the spring 101 operates between the guide 102 resting against the arm 98 and a washer 102 under the spring 101 to normally force the lock into locking position.' 103 is a nuton the rod 69 to clamp a bracket 104 onto the set nut 104 on said rod 69. Said bracket is slidable up and down on the rod 97 so'that when the rod 97 is forced up by pressure on the piston 93 from chamber 72 the spring 105 on the unlocking rod 97 acts through the bracket 104 after lock 98 is released to force down the valve rod 69, thus to open outlet 71 from the pressure chamber and permit the liquid therein to How by gravity into the expansion chamber 71. The roller 69 is thus brought torest on the cam wheel 23 and the parts remain in the position shown in Fig. 150 until another operation'of the crank serves to turn the cam 23 and a ain lift the rod 69, the valve and valve 4.

The moment the rod 69 is lowered, its head 103 is withdrawn from the valve rod 73, thus allowing the valve 74 to close and remain closed and the valve 70 to be opened by spring 105 and to remain open until another operation of the cam wheel 23 has occurred, Whereupon the operation just described will be repeated.

The adjustment ofthe set nuts 97 determines the lift of the syrup piston and enables the operator to predetermme the amount of syrup to be delivered at each operation of the machine.

This enables the operator to properly proportion the syrup to the water so that syrup of various degrees of concentration may used. The chamber 62 is of larger dimensions than the amount of syrup usually required for the charge of carbonated water so that the regulation can be to either increase or diminish the charge of syrup.

By experiment I have determined that when the liquid is heavily charged with gas, the actual liquid in the chamber 72 is so increased in bulk by the presence of the liberated gas therein, that the float will be lifted by a less quantity of actual liquid in the chamber 72 than when the pressure in the suppl drum or tank 78 is lower, and as the heavil;7 charged water produces a greater amount of foam than the lower charged water, consequently by this method of cutting oli the flow of charged liquid into the chamber by the pressure in the chamber, the amount of liquid and gas delivered to the cup along with the syrup and the resulting foam will in 'each instance fill the cup tothe pre determined height so that a full cup will be served at each operation.

The cylinder head 90 may be threaded into the power cylinder 89, the weight 91 is fixed to the piston rod 91 by set screw 91 and the arm 96 is fixed to said rod 91 by set screw 96 so that by removing the casting 55 from the member 2 the parts can be easily disassembled,

The piston 93 by which the pressure from the tank 78 and chamber 72 is applied to pump a predetermined measure of the syrup and to release the valves to close the supply Valve and open the outlet valve, is spaced above the pressure port 88 so that there is always a gas pocket 93 below' the piston 93 thus to cushion the' piston against the force of the liquid from the tank 78.

The-cover 56 is recessed at 56a so that the chamber 89 is open to the atmosphere above piston 93 to permit easy reciprocation of the piston.

Ratchet means are provided to prevent retraction of the dispensing mechanism after starting until completion of its cycle. The same comprises wheel 23, and a ratchet wheel 106 integral therewith and a finger 107 pivoted at 108. Said finger is provided with a shoulder 109 thatl engages the teeth of said ratchet and prevents said ratchet. and cam 23 from revolviner in a reverse direction. A Weight 111 mares the finger 107 more positive in its engagement with said ratchet.

The pressure valve chamber 112 formed in the nipple 86 is supplied with efervesccnt liquid through a minute port 113 so as to cut down the flow of the pressure liquid on its way to the pressure chamber, and such valve chamber serves as an expansion chamber to allow the gas to expand on its Way to thev pressure chamber and to seat the pressure liquid inlet valve instantly when it is unlocked. i

The operation of the invention is as follows:

A coin of the required denomination is placed in the slot 12 and runs down into the grooves 12 and seats in the seat 9a of the coin carrier and providing means for connecting the shafts 8 and 15, thus bridging the opening between the limbs of the coin carrier.

The crank 7 is then turned to the right in Fig. 14 and the coin engages the lug 14 and turns the sleeve 10, shaft 15 and gear 17, thereby turning the gear 18, its shaft 19, the gear 21 and its shaft 22, and, acting through the sprin 22a turns the shaft 22 and the cam whee 23.

The oscillation of the crank 7 is sufciently ample to turn the crank pin 27 in the direction'of the arrows on and adjacent the cam wheel in Figs. 10 and 15, until the crank pin has swung down and past a vertical, not shown, drawn from the axis 22 of the cam wheel, when the manually tensioned spring 27 operates with a snap action to suddenly complete the revolution of the cam Wheel to drive the Dear 21 in the direction in which it was turned b the crank, thus completing the revolution of, said gear 21 and the train of gears and shafts connected therewith.

When the cam wheel 23 has revolved to the top of the cam or tooth 23', the rod 69 has been lifted to such point that the shoulder 100 is above the tip of the loclr limb 98 of the locking rocker or support and the spring 101 acting on the arm 93 throws the top of the lock limb under the shoulder 100, thus holding the outlet valve 7 0 in closed position as shown in Fig. 17.

The snap action revolution of the gearv21 operates the gear 17, shaft 19, gears 39 and 40, shaft 41, gears 42 and 43 and completes the revolution of the cup delivering wheels 31, so that when the cam 23 comes to rest, a cup C has been delivered so that it hangs by its rim b on the lip lla.

When the cam is revolved from the normal position in which it is held by the springs 27, the periphery of the cam lifts the roller 69, the rod 69 and the valve 74 against the pressure of the pressure liquid in the pipe 79, thus allowing the pressure liquid to liow through the slot 76 into the chamber 72, while the outlet 71 from such chamber is closed by the lifted valve 70.

As the liquid rises in the pressure chamber and after the vent holes 84 are closed by the float 80 the pressure in chamber 72 is communicated through the port 88 into the bore 89 and lifts piston head 93 and the pump piston 92 which in turn lifts the syrup 1n the syrup chamber 62, thus forcing the syrup u through duct and through port 65', until a charge of syrup has been delivered to syrup outlet chamber 64 from which it flows by gravity through the port 66 and pipe 67 into the conduit 94.

t the close of the upward movement of the piston 93 and its rod 91, the arm 96 is carried upward by the rod 91 end acting against the stop 97', lifts the rod 97 and collar 97a which lifts the arm 98 and rocks the valve lk on its pivot 99 and this withdraws the lock limb 93 from under the shoulder 100 which is normally supported by the lock limbv '3l-"he eervescent liquid2 from the supply tank 78 is normally so highly charged with gas that it is necessary to allow a. portion of the gas to escape from the pressure chamber in order to establish a sufficient charge of liquid in the pressure chamber to afford requisite water for the drink, which is ordinarily in the proportions of about five ounces of water to one ounce of syrup, and therefore, I make provision in the form of the vent holes 84 to permit escape of some of the gas.

The inlet 63 into the fpump cylinder extends from the bottom o said cylinder to a sufficient clearance above the top of the pump piston 92 to allow theiip-thrust of the piston to cut off the inlet with suflicient quantity of the liquid above the port to supply the maximum amount of syrup for a drink, and the upward travel of the piston being limited by the position of the stop formed by the nuts 97', the amount of syrup expelled from the pump cylinder and caused to overflow through the port 65 can be accurately determined by adjusting said nuts.

When the pressure below the power piston 93 is relieved by o ning/the outlet valve 71 at the bottom of)e the preure chamber the piston rod 91 and the pump piston hea 92 are lowered by gravity, and the weight 91 assures completion of this operation. The piston head 92 is allowed to descend because the syrup which has flowed from the fountain into the space underneath the pump piston, flows back toward fountain 57 during the descent of the pump iston head and re turns again to cover the piston with the syrup flowing from the fountain to fill ump cylinder 62 to the level f as shown in igs. 24, 25 and 26.

The charged water from pressure chamber 72 is emptied into expansion chamber 71 so that the water delivered from chamber 72 will be retarded before flowing into the conduit 94 until the gas pressure in chamber 72 is relieved and the water permitted to flow by gravity from the chamber 71'.

The liquids flowi down the conduit 94 are mixed therein an projected over the drip cup into the cup C where they are finally mixed by the force of the discharge; and any drip from the spout 38 falls vertically into the drip cup 5 so as to avoid smearing the drinking cup.

An advantage of my device is that the piston rod 91 when moved u wardly by the pressure in the pressure cham r through the cylinder head into the bore 89 will be thoroughly cleansed by the water from the chamber 72 entering the bore 89, and thus remove any syrup that ma have adhered thereto and passed throng the cylinder head 90.

The pressure in bore 89 also exerts a force around the rod 91 at the opening in head 90 where said rod passes through t e head and tends to prevent the syrup from being pulled through such opening with the bore 89.
