Referring to the drawings in which like reference characters indicate like parts, 1 designates-the cabinet or outer housing of our novel beverage dispensing apparatus, being any suitable shape and formed of a plurality of panels 2, and a front or main panel 3, upon which are mounted the various exposed parts of the apparatus, such as the sight glasses 4 and `5;vthe serving door 6; the trap door 7 leadingtoa waste container for the disposal of all the Waste or used cups; the series of coin .slots 8; the correponding series of operating handles or knobs 9; and the series of name plates 10, corresponding to said series ofcoin slots and op'- erating knobs, for designating the particular flavor of drink corresponding. to any `particular coin slot and operating knob. A

. Within the cabinet l, are disposed the operating parts of our noveldevice, land 1n particular, there is located, preferably in one of the rear corners of the cabinet, a steel storage tank or gas bottle 11, of the usual commercial type, containing a supply of carbonic acid gas, or carbon dioxide, under pressure, and which is hereinafter referred to as the gas. The refrigerator tank 12, located at the bottom of the cabinet 1 and occupying the major portion of the bottom area thereof, is provi-ded for refrigeration of the water A used to prepare the carbonated water :for the mixed beverage, and may also, if so desired, be used for `storage of the water as Well; that is, a mixture of drinking water and pure ice may be placed into the tank 12, and the Water may then be drawn into the carbonating battery directly from such ice and water mixture. If desired, the tank 12 may be merely utilized as a refrigerating chamber, the drinking water being supplied' from the water mains through suitable pipes. In either event, the carbonating battery 13 is disposed within said refrigerating chamber 12, thereby effecting a cooling of the water in either case, as it passes through the battery 13.

The series of syrup tanks 14, corresponding to the series of coin slots 8 and operating knobs 9, are positioned in the uppermost part of the cabinet 1, extending rearwardly alongside of each other, and supported by suitable brackets l15, which in turn are secured to the rear face of the` front panel 3. The cup dropper 16, of any suitable construction, is also mounted upon the rear face of the main panel 3, as shown, in Figures 5, 9 and 13, and is provided with the glass reservoir or container 17 for the storage of a `quantity of nested paper drinking cups. It will be noticed that the glass reservoir 17 is positioned behind and in alignment with the sight glass 5, thereby permitting the visual inspection of the container 17, for the purpose ofascertaining, the quantity of paper cups contained therein at any time. The paper cups .18, as they are released from the cup dropper 16, are jthenv guided by means of the guideway 19 into a cup support 20, positioned yupon the serving platform 21, which is carried by the hinged serving door 6.

The two end frame members or plates 22 and 23, also secured to the main panel 3, are provided as supports for the series of ejectors or pumps 24, corresponding to the series of'syrup tanks 14, and also support the main shaft 25, and thecontrol valve and mixing chamber casing 26.

Referring to the drawings more in detail, our novel mixed beverage vending apparatus is adapted to carry 4out a cycle of operations as ollowsz--upon .inserting a' coin into any one ofthe series of-coin slots 8, the corresponding knob 9 andhence the corresponding operating lever 27 is released from its normal or' locked position, by meanaof the coin control mechanism shown particularly in Figures 2 to 4 inclusive.4 The `operating lever 27 is loosely mounted upon the main shaft 25, and carries .a lug or dog 28 adapted to encounter a suitable pin or other projection 29 carried by said shaft. By suitably adjusting the relative positions of the dog 28 and the pin 29, the lever 27 can be made to engage the control shaft 25 at any desired pointin its downward travel, which adjustment, as will be brought out more. in detail hereinafter, is essential to the proper timing of the control valve, syrup pumps and cup dropping device.

The pivot bolt 30 is mounted upon the lower extension of the lever 27 in an adjustable manner, in thefslot 31 and below the main shaft 25. The bolt 30 carries a connecting rod 32, which is in turn pivotally mounted at its other extremity upon the wrist pin 33 of the piston 34 of the pump or ejector 24. Thus the downward movement of the lever 27 effects an ejecting stroke of the piston 34 ofthe syrup pump.

The packing gland 35 is threadedly secured upon the end of the cylinder 36, of the pump and effects, a packin of the piston 34 with respect to said cylin er, by the compression of a suitable packing material 38, as shown vin Figure 15. -The pump 24 is provided with a terminal passageway 39, extending transversely of the cylindrical poi'- tion 36 thereof and communicating therewith, and havingthe upper and Y lower threaded ends 40 and 41 respectively. One or the other of these threaded ends is closed up with a suitable plug or other threaded c osure 42, andthe packing 43, while' the Uil Ilm

other threaded end has 'attached thereto, the

ling nipple 47 of one of the check valves 48, a,

which are carried by, and communicate with the mixing chamber 49,.of the controlvalve 26, of our n ovel apparatus, as shown particu- 1n vFigures 5, 9,v 11, 12 and 1'5. The.v

larly check valve 50, threadedly secured to thev tting 44, by means of the threaded end 51 is provided with the valve ball 52, which is adapted to seatnpwardly against the valve ne l seat 53 when raised by a liquid flowing up- 'wardly. The check valve 50 is also provided with a nip le 54, for the attachment thereto of one en of a' flexible hose 55, said hose having its other end similarly attached '.to an outlet nipple 56 on the corresponding syrup reservoir 14. Thus, upon drawing down anyone of the .operating knobs or handles 9, carried by the puter terminalsof vthe correspondingoperating levers-27, inthe direction of the arrow 57, the" lower extension of the lever 27,

tlirou'gbv theconnectngrod 32, 'will aetaxate-v the iston 34 of the corresponding pump 24, in t e direction of the arrow 58, thereby to force out a fixed and predetermined quanti. ty of syrup from the`cylinder'36 thereof, t rough the transverse passageway 39 into the fitting 44. The syrup forced out by the piston 34, rais'es the checkvalve ball 52 against the valve seat 53, thus preventing the retreat of the syrup tothe reservoir 14, and thereby causing the syrup to pass out throu h the nipple 45 and the corresponding iiexillc hose 46, into and through the corresponding -iexible hose 46, into and through the corresponding check valve 48, into the mixing chamber 49, of the control valve 26.

The check valve 48, shown particularly in Figures 11 and 12, consists chieiiyV of the valve member 59, of any suitable shape, such as the spherical valve ball shown in the figures, carried by the valve stem 60, and held against the seat 61 in a direction outwardly of the mixing chamber 49, bym/cans of the helical compression spring 62, interposed between the spring seat 63, on the end of said valve rod and the stationary spring seat 64, carried by the casing 48 of the check valve.

Upon the reverse stroke of the piston 34, into its normal position, shown in Figure 15, the syrup from the corresponding tank 14, gravitates down into the cylinder 36 and the passageways interconnecting it with said cylinders 36, and completely fills the same. Thus, with each operating stroke of the lever 27, a given and predetermined uantity of a. corresponding syrup is forced into the mixing chamber 49. The mixing chamber 49 is provided with the discharge nozzle 65 and the gravity check ball 66, seated upon 'acorresponding valve seat 67, whereby the charge `of syrup forced into said mixing chamber'49 will be retained therein, unt-ilv the valve ball 66V is raised from its seat, by the discharge of the carbonated. water into said mixing chamber under considerable pressure and hence with considerable force. as will be brought out more in detail hereinafter.

The control valve 26, as will be seen particularly in Figures 11 and 12, and Figures 16 to 24 inclusive, consists of a housing 68 having a series of threaded openings 69 in the periphery thereof, for the reception of the threaded ends 70 of the series of check valves 48, through which `the various Syrups are delivered to the mixing chamber 49, within said housing 68. The o ening 71 is provided in one end of the cylin rical casing or housing 68, for 'the reception of the rotary valve stem 72. The outer projection or boss 74 having an enlarged opening internally threaded, is adapted to receive a. suitable packing material 75, and the correspondingly threaded packing gland 73 adapted to compressV said packing material, thereby to ,68 of t make a .perfect sealing joint betweeii the said valve stem 72 and the opening 71. The rotary valveportion or disc 7 6, carried ri idly by, and preferably formed integral, wit the valve stem 72, is seated snugly and is journalled within the corresponding annular opening 77 in the other end of the casing e control valve 26, in such a manner that the cylindrical periphery 78 of the valve disc 76, contacts throughout its entire circumference, over part of its width, with said annular openin 77.

The open end of te casing 68 is provided with a pair of guides or lugs 79 projecting horizontall therefrom and having the right angle mem ers 80, which are provided with suitable threaded openings 81. A stationary valve` block 82, containing the stationary ports of the valve, is provided with suitable channels 83 betweena pair of parallel guideways 84, on each side, which channels are adapted toreceive the guide lugs 79, thereby accurately and rigldly to position the valve block 82' with vrespect to the rotary valve disc 76. The face 85 of the valve block 82 is recessed slightly as shown in Figures 12 and 24 `and isthus adapted to receive and retain a suitable leather packing disc or plate' 8 6, having a series of openings corresponding to and coincidin wlth the ports in the face85 of the valve lock 82, which plate thereby acts as a acking medium between the stationary an the rotary ports of 'the control valve.

In order to retain the stationary valve block 82 in position Vand pressed tightly against the face 87 of the rotary valve disc 76, a yoke bar 88 is secured to the right angle projections 80, by means of the bolts 89,.which yoke is provided with a set screw 91 threaded through the center of the yoke and adapted to enga e and bear against the center of the, valve block, therebyv to exert an even pressure upon said block, and thus to force the same against the face of the rotary valve disc 76. .The collar 92 preferably formed integral with the valve stem 72, is butted up against the inner wall of the valve casing 68, thereby preventing any axial movement of the valve disc 76, due to the pressure of the set screw 91.

The carbonating battery 13 is disposed within the refrigerator chamber 12, thereby to cool the water as it is being carbonated, so that it may absorb the maximum amount of gas. The refrigerator chamber 12, as

mentioned above, may be used in any one of two ways; namely, it may be used mainly for a refrigerating medium through which water is passed from an extraneous source, in which case the chamber'may be filled with ice and salt, brine or any other refrigerayting medium; while onl the other hand it is equally practicable, and under certain conditions more desirable, to utilize the chamllU ber 12, both-`as a refrigerator chamber, as well as a reservoir for the water to be used in the carbonating process. In thislatter case the chamber 12 is filled with potable water to a substantial height and then a suiicient quantity of pure and wholesome ice is added. 'The water used in the carbonating process is then drawn in to the carbonating battery 13 by suction, from this mixture of ice and water Within the chamber 12 and immediately surrounding the carbonating battery. l

The carbonat-ing battery 13 consists of a lower manifold 93, the upper cover plate 94, a series of upright and preferably cylindrical absorption chambers 95, 96 and 97 interposed between said manifold 93 and said cover plate 94 and a mixing chamber 98 carried at the end of said manifold, for the purpose of premeasuring a quantity of carbonated water, to be dispensed with each operation of the apparatus. The water to be carbonated, is drawn either from an extraneous source such as the city water main, or directly from the chamber 12, surround- -ing the absorption battery 13, through the inlet opening 99 at one vend of the manifold 93. The Water is, moreover, drawn into said inlet 99 by suction created intermittently within the chamber 97, and entirely independently of outside pressure, as will be described more in detail hereinafter, in conneet-ion with the detailed operation of the main control valve 26.

The valve 26 of our novel construction,

l shown particularly in Figures 5, 9, 11, 12 and 24, is Inounted upon or secured to the frame' member or end plate 22 in any suitable vmanner, not shown in the drawings. The valve block 82 is provided with the fiveinlet ope-nings or passageways 111 to 11-5 inclusive, to the outer terminals of Which are attached the respective pipes 101 to 105 inclusive, and the inner ends of `which terminate in the stationary ports 121 to 125 inclusive, iny the face of the valve block. A stationary relief port 128 is also provided in the annular opening 77 of -the casing 68 ofthe valve. By means ofthe series of pipes 101 to 105 linclusive, the stationary port 121 is thus in constant and direct communication with the gas storage tank 11; the port 122 is connected with one end of the manifold 93 of the absorption or carbonating battery 13; the port 123 is connected with the inlet end of the absorption battery; the pipe 104 is connected with the top of the measuring chamber 98; while the pipe 105 is connected with the manifold 93, intermediate of the measuring chamber 98 and the series of absorption chambers 95. The relief port 128 opens directly into the atmosphere, through the passageway 118, as shown particularly in Figure 12. 4

vThe rotary or disc portion 76 of our novel after.

The operation 'of our novel'control valve valve is provided with a second series of ambulatory or 'movable ports 131 to 137 inclusive in its face 87, contiguous to the face 85 of the valve block 82, and the port 138 in the peripheral surface 78 thereof, corresponding to the port 128 inthe valve casing 68, as shown in Figures 12, 17 19, 20, 21, 22 and 23. The rotary or disc portion 76 of the valve is further provided with a series of passageways 141, 142, 144,146, 147 and 149, interconnecting the various ports in said disc in the manner shovvnparticularly in Figures 19 to 23 inclusive. In the Figures 16 and 17 and Figures 18 and 19 there are shown the relative positions of the ports and passageways of the stationary and rotary portions of the valve in the open and closed positions thereof respectively, which two positions are approximately 45 degrees aparts, as indicated by the line 148. Thus in the normal, inoperative, closed or off position of the valve 26, the, gas tank 11 is connected through the pipe 101, the stationary port 121, the movable port 131 the passage-way 141, the movable port 133, the stationary port 123 and the pipe 103, with the upper end ofthe absorption chamberv 97, at the entrance end of the carbonating battery 13. Similarly the ports 132 and 135 are interconnected by means of the passageway 142, as shown particularly in Figures 17, 19 and 22, while the ports 136, and 137 are connected by means of the passage-ways 146 and 147, to an axial passage-way l149 extending into the valve stem 72, and communicating with a series of radial discharge v openings 150. It will here be noted'that the passage-way 146 joins the axial passageway 149, a slight distance behind the point where the passage-way 147 connects with said axial passage-way, so that the fluid passing therethrough, will pass the junction point of the passage-way 146 and the axial v I passage-way 149, with sufficient velocity as to create a suction in the passage-way 146. This suction or jetting action of the water ypassing through the passage-way 147, upon the passage-way 146 is utilized to create' a suction within the first absorption chamber 97 of the carbonating battery 13, when the valve is in thel open or operative position,

thereby to draw in a fresh supply of water, independently of the pressure of such water, as will be described more in detail hereinis as followsz--In the normal, closed or off, position of the valve disc 76, that is, inthe position shown in Figure 17 relative to the stationary valve block 82, as yshown in Figure 16, the gasV tank 11 is connected through the pipe 101 and the stationary port 121, the movable port 131, the passage-way 141, the port 133,"the stationary port 123, and the pipe 103; to lthe first absorption thereof, forces the water within the chamber 97, into and through the manifold compartment .153 and through the upright spray pipe 154, causing it to raise the ball chec valve 155 and thus forcing it out through the upper perforated end of the dispersing funnel 156 at the top of the spray pipe 154, into the second absorption chamber through 'which thewater, admixed with gas,

descends in the form of spray through theA screen 157, thus causing a rapid absorptionof the gas by the water. The water thus continues through the following absorption chambers 95 in a like manner, passing successively through the series of similar manifold compartments 158 and the corresponding series of upright spray tubes 159, posi-` tioned centrally with respect to said absor tion chambers 95, in a manner shown 1n Figure 14, and provided with u per perforated ends 160. Each of the a sorption chambers 95 is similarly provided with the screen 161 to facilitate the rapid absorption of the gas by the water. The lower manifold 93 is further provided with the compartments 162 and 163, and has mounted thereon a measuring chamber 98 in. such a manner that it communicates freely with the last compartment 163, while it communi- Cates-with the compartment 162 throughfa valve seat 1.64, uponl which is seated a ball check valve 165, thereby to limit the passage of the water from the compartment 162 into the measuring chamber 98. The pipes 102,

104 and 105. are connected, in a manner shown in Figure 14, with the compartment 163, the-top of the measuring chamber 98 and the compartment 162 respectively, there-A .by establishing communication between the same and the stationaryports 122, 124 and 125 respectivel There is further provided a checkvalve all 166, normally carried by a; retainer or basket 167, adapted Y.to seat against the upper entrance or o en1ng168 and to be raised bv the liquid in e measuring chamber 98, thereb to prevent the exit "of such liquid throng the pipe 104, but yet to permit the passage of as throughthe same pipe, as w'ill be descri ed more 1n detail hereinafter.

The charging or carbonating operation,

' as described above, takes place during the oiv or closedposition` of the valve, by-

the direct -action lof the lgas from the tank 11 .u on the water contained and trapped within the first absorption chamber 97. In this oip position ofthe valve, shown in Figures 16 and 17, the stationary ports 122 and125 are interconnected by means of the movable ports 132 and 135 and the passageway 142, thereby establishing an equilibrium of pressure between the compartments 162 and 163; While ythe port 124 communicates with the movable port 134 and hence connects the measuring chamber 98, through the passage-way 144 and the movable port 138 with the stationary port 128 and the passage-way 118, with the atmosphere. In this position any gas contained within the measuring chamber 98 is thereby relieved through the passage-way 118 since the force ofthe gas alone passing through the open- 96, ing 168 and the pipe104 is not suiiciently strong to raise the ball check valve 166. Thus, as the gas in the measuring chamber 98 is displaced bythe carbonated water, urged by the pressure of the gas in the absorption chamber, vit rises until it raises and seats said ball 166 upwardly, against the exit opening 168, thereby shutting of the measuring chamber 98 from the relief passage-way and opening 118. Thus, agiven `quantity of carbonated Water is now contained and retained within the measuring chamber 98v during the oii:', closed or inoperative position of the valve.

Upon turning the valve, however. into the operative, open or on position.' shown in Figures 18 and 19. the stationary port 121, heretofore connected with thel absorption chamber 97, is shunted through the passage way 141 to the stationary port 124 and hence to Ythe top of the measuring chamber 98 fthrough the pipe 104. In this position` .moreover, the stationary port 125. shut of by the blank surface. in the face of the valve disc 76, while the stationary port 122 com.- municating'withy the pipe 102 and the com-V partment 163 in the manfold v93', is met by the .port 137 and connects through the passage-way 147 with the axial passage-way .149' andr hence with the radial discharge Aopenings 150. Thus, the pressure of` the gas from the tank ,11, acting upon the surface of Vthe Water in the-measurlng chamber 98. forces the same lout through'the compartment 163 and the pipe 102 out through the passage-ways 147 and 149' and the disf charge openings 150, into the mixing chamber 49; theball check valve 165 preventing the retreat ofthe water from the measuring chamber 98 back into the compartment 162. In the open or operative position of the valve, moreover, the stationary port 123,`1s connected through the movable p ort 136 and the passage-way 146 with the axlal passage# way 149 at a` point slightly back of zthe passage-wayV 147 as brought out 1`n detail lll) hereinbefore and shown particularly in 'Figure 23, thereby the suction or jetting action created by the water passing through the passage-ways 147 and 149 creates a suction within the absorptionchamber 97, suliicient to raise the check valve ball 151 and to draw into said chamber a fresh supply of water. Upon again returning the valve into the normal position, shown in Figures 16 and 17, the cycle of operations is again commenced, that is, the gas remaining within the measuring chamber 98 after the displacement of the carbonated` water therefrom, is relieved through the opening 118.

a and the carbonation of the fresh charge of water is then carried on through the various absorption chambers until the measuring chamber 98 is again filled completely with the carbonated water.

In ord-er to obtain the desired mixing of the syrupl and the carbonated water, it is necessary to deposit the syrup into the mixing chamber 49, substantially prior to lthe discharge of the carbonated water thereinto.

This is readily obtained by an adjustment of the relative positions of the dogs 28 and the pins 29 throughoutthe main shaft 25,

so that the main shaft will notbe operatively engaged by any of the levers 27, until such levers 27 have actuated the corresponding pistons 34 of the pumps 36 through the major portion oftheir stroke, so that the discharge of the syrup into the mixing chamber 49 will precede the discharge of the carbonated water thereinto; although the two discharges may overlap each other.

In lorderto effect an automatic return of the` levers 27 and the operating knobs 9` anyone of several means may be resorted to. Thus,` if desiredfthe levers 27 may be provided with .lower horizontal extensions 169, upon which may be adjustably mounted the counter weights 170 located in any` suitable position by the set screw 171, as shownf particularly in Figures 12 and 15. If desired, however, .the levers 27 may be returned by the pendent counter Weights 172 supported by the iexible cords or chains 173 passing over the idler pulleys 174 and 'engaging the levers 27 at a suitable point 175 as shown in Figure 7.. Still another means of returning the levers 27, is shown in Figure 48, wherein a tension spring 176 is.

interposed between a suitable point 177 on said levers 27 and a fixed stationary support Inorder to deposit a new and unused cup 18 from they cup dropper 16 into the cup support 20 carried by the serving platform 21, as mentioned hereinbefore, there is provided a rocker arm 179 pivotally mounted 'upon the pivot 18() and having one arm 181 Y thereof in alignment with the actuating lever 182 of the cup dropper and having its other arm 183 extending into 'operative alignment with an actuating arm 184 carried rigidly by either the main shaft 25 or the valve stem 72, which is a continuation thereof and which is coupled thereto by suitable means such as the coupling ends 231 and 232. By this means the actuating lever or arm 182 will be turned in the direction of the arrow 185 with the movementv of the main shaft 25, and by so positioning'the arm 184 as to engage said rocker arm 179 during the first part of its movement and by so proportioning the relative lengths of the arm 181, 183 and 184, the cup 18 is released and deposited on the serving platform beneath and in vertical alignment with the nozzle 65, before the valve disc is moved into the lfull open or operative position shown in Figure 19, hence, prior to the discharge of the carbonated Water into the mixing chamber and prior to the discharge of the mixed beverage through said nozzle 65. As mentioned above, the serving platform 21 is carried b the door 6, pivotally mounted upon the hinges 186 and provided with the glass panel 187 so as to expose to view the cup positioned upon such serving platform. Suitable means may be provided for yieldably retaining the door 6 in the closed position. Such means may consist of a spring, counter weights or the like. A vertical flange- 188 is further provided, surrounding said platform 21 for the purpose of damming any liquid that may be spilled or that may over-flow from the cup, and is further provided with a small drain pipe 189 in one corner of said platform 21 which extends.

'f ing of the mixed beverage produced within the apparatus' as` described above, there are provided a series of coin control devices interconnectedwith the actuatinflr levers -27 in such a manner as to normally retain the same locked in the upper or inoperative position and to release the same only when a suitable coin is inserted into the correspondinv' coin slot 8. Thus, therel are provided suitable uprightl elongated apertures in .the frontpanel 3 of the cabinet, over which are fitted the plates 196 carrying the guide-ways 194. The guide-ways 194 support and guide the 'upright slide 195, which is also provided with a corresponding movable coin slot 8. The slide 195 is provided with a slot or 'aperture 197 through which the operating' lever 27 passes, so that the slide 195 will CTI necessarily be l'drawn ldovs'nwardly in its guide-way 194, when-the lever 27 is moved downwardlv during the -working stroke of the same. hus, in order-to lock the operating lever 27 in itsu per position, suitable means is provided orf locking the slide against the downward movement. This lock comprises a catch 198 Bivotally mounted upon the slide 195 upon t and an upright rack 200 rigidl carried'by one of the guide-ways 194 an having its teeth provided with substantially horizontal edges 201 and lower upwardly inclined edges 202. The-slide 195 also supports a co'in plate 203, shown particularly 1n Fi res 3 and 4, which coin plate is'positioned irectly above the coin slot 196 and a small auxiliary coin guide bracket also carried lby the slide 195. The coin plate 203 is-also provided at its farthermost edge with anv overhanging and horizontal nose piece or support 205 adapted to enga e the edge of the coin as it is passed throng the coin slotl 8 and thereby to retain said coin in a horizontal position. The catch 198 is further provided with a downwardly extending linger 206 (projecting down below the coin plate 203 an adaptcd to oscillate to and fro in a direction parallel to the slide 195 within a slight recess 207 in one edge of said coin plate 203 adapt- I ed toreceive such finger l206. There is further provided a second `tube rack 208 provided with teethv 209 and lower horizontal edges 210 and the upper inclined edges 211.l The spring 212, pivotally supported upon the pivot screw 199, is interposed between the catch 198 andtheupper surface of the coin plate 203 in a manner shown in Figure 2, so as to retain said catch in operative enjgagernent with the teeth of the rack 200.

By this novel construction, as the coin is inserted into the coin slot 8, it encounters the fingers 206, forces .the same outwardly against the force of the spring 212 and thereby withdraws the catch 198 from engagement with the teeth -of the-rack 200. As the coin is fully4 inserted into the coin slot 8, moreover, thelinger 206, urged by the force of the spring 212, moves the coin to one side inthe direction of the rack 208, thus forcing the -edge of the coin against such rack. 'The' coin thus inserted, having withdrawn the catch 198 from engagement with the rack 200, ermits the downward movement of the slide 195 and thus permits the operation of the lever `27 and hence of the dispensing apparatus. As the slide 195 is thus moved downwardly by the lever 27, the edge of the coin carried by the guide bracket 204 and the nose .piece 205, successively engages each of the teeth 209 of therack 208 1n its downward travel, and since the lower edges 210 of said teeth are substantiall horizontal, it will interlock vwith such e dges in such a manner as to prevent the sli e 195 e pivot screw 199, l

and the lever4 27 from being moved -upwardly andhence from being returned to its upper normal position beforethe lever has beenV moved .into its lowermost or operative position. Hence, after the slide hasl been moved down to its lowermost position, that is, when the edge of the coin has passed,v the lowermost tooth 209 and has passed the lower end of the rack 208 the coin is ejected from its I osition beneath the'coin plate 203 by the 1 orce of the finger 206; `The coin being thus the coin slot 196.v Suitable means may be provided for-receiving the'coins as they are ejected from beneath the coin plate 203, such not being shown in the ydrawin s.

In order further to lock any particu ar opera-ting lever 27 and knob 9 in an inoperative position and to prevent the insertion of a coin into the corresponding coin slot 8, when the'v correspon-ding syrup, reservoir 14 does not contain a suiiicient quantity of syrup to produce the beverage, there is provided novel l syrup control locking means shown particularly in Figures 2 and 10. Thus, as shown vin Figure 2, there is provided a dog' 213 carried by a vertical sliding rod 214, guided by suitable guides215, whlch sli-ding rod is extended out horizontally as at 216 and is,

provided with a second vertical sliding portion- 217 extending into thev corresponding syrup tank 14 and guided by the guides 218.

vThe vert-ical slide 217, carrying a oat 219 at the lower extremety thereof,`which in its uppermost position, and hence in: the uppermost position 4of the dog 213 is in close proximity to the bottom of the reservoir 14. Thus, so long as the level of the syrup 220 within the tank 14 is above the predetermined low level, it will retain the float 219 and hence the dog 213 in the raised position shown in Figure 2. lWhen, however, the level of the syrup falls below the predetermined low limit, tliedog 213 is lowered into a position between .the'f edge 221- of the catch 198 and the straight edge 222 of the rack 208.

In this drawn osition, thef catch can not be withinserted 'into the coinslot 8, being obstructed by the finger 206. Upon refilling of theparticular reservoir, the rod-219 and hence theI` rom engagement with the teeth'ofthe rack 200 and hence the coin can not be over, the operation of the apparatus controlled by such device is limited to a coin of the proper denomination, as determined by its dimensions. Thus, if a coin of a smaller size is inserte-d, it will either fall through without being retained by the nose piece 205, or if it is retained beneath the coin plate 203 by the nose piece 205 and yet falls slightly short of the required diameter, it will not entirely clear the catch 198 from the teethof the rack 200 and therefore will not release the slide 195. On the other hand, if the coin is too large it will, naturally, not enter the coin slot, which is purposely made of exact size.

In Figure lOthere is shown almodified form of a float controlled locking device' for locking the slide 195 in an inoperative posi-` tion and for preventing the insertion of a coin into the coin slot when the level of the syrup within the tank 14 is below the pre determined low limit. In this modification the float 223, upon the lowerend of the rod 224, is carried by one end of the rocker arm 225 pivotally mounted at the point 226. A p'awl 227 is-pivotally mounted at 228 in align-` ment with the catch 198 and is interconnected with the other end of the rocker arm 225 by means of the rod or cord 229, so thatl as the float 223l is lowered it raises the outer end 230 of the pawl 227, thereby moving said pawl 227 down into engagement with the catch 198, thereby locking the same in an inoperative position in a manner similar to that sh'own in Figure 2 and with like effect upon the insertion of a coin into the coin slot 8..

It will now be apparent that we have devisedda novel and useful mixed beverage vending apparatus which embodiesy the features of advantage enumerated as desirable in the statement of the invention and. the above description, and while I have, in the present instance, shown and described apreferred embodiment thereof which 'will give in practice satisfactory and reliable results,
