PRITZ, OF GERMAN- TOWN, PENNSYLVANIA, ASSIGNORS OF ONE-THIRD T0 JAMES DELPHIA, PENNSYLVANIA BEVERAGE MIXER ANI) DISPENSER Application filed September 15, 1928. Serial No. 306,240..

The object of the invention is to provide improvements broadly in beverage dispensing means, such as are automatically controlled by the use of a coin of predetermined size or denomination, and which dispensing means is ivholly independent ot anyvoutside agency for its complete operation after being properly supplied with the ingredients of which the beverage or beverages are composed. l

More particularly the invention provides for the proper measuring of definite quantitics ot any desired syrup with such a fluid as carbonated water under pressure, said syrup and Huid being mixed and dispensed into a suitable container such as a :paper cup, which cup has been released from a magazine, and which cup when filled with a predetermined quantity operates to release a door or other element, which until a given point in the operation ot the device bars access to its interior.

Another object is to provide an ingenious arrangement of suitable mechanism, 'whereby the pressure from Within the Well-known carbonated Water or other tank serves as t-he actuating means for the complete operation of the said mechanism. upon its release by the application of the coin above referred to, said pressure no matter Wh at it may be within the tank being reduced to any desired operating pressure. and being operative after the com.- pletion of the cycle of movements to reset the mechanism so as to respond immediately upon the application of a second coin, and so on until the tank is devoid of its fluid contents.

Further objects consist in providing novel means for the rejection by the device ot any under-sized coin. that is for instance a cent or dime when the proper operating coin is a nickel; in providing novel means for the -release of a cup from its magazine into operative position by and during the operation of the fiuid controlling mechanism; in providing door release latch mechanism actuated by the cup upon becoming properly filled; in providing suitable retrigerating means for cooling the syrup and carbonated water; in providingr novel means for measuring` first line 2 2 of Fig. 1 Fig. 3 is a section on the line 3 3 of Fig. 1; Fig. 4 is a section on the line 4 4 of Fig. 1; Fig. 5 is a section on the line 5 5 of Fig. 1; Fig. 6 is a section on the line 6 6 of Fig. 1; and Figs. 7 and 8 comprise sections through a part of the operating portions of the device with the respective elements embodied therein shown in different positions corresponding With diierent phases' in the operation ofthe mixing and dispensing mecahnism.

Referring to the drawings, an outside cabinet may be made of any suitable shape, but in the present instance comprises a front Wall 1, having an -aperture 2, normally closed by means of a door comprising a frame 3 surrounding a preferably transparent panel 4, said door being held normally in closed position by means of a latch comprising an arm 5 which is carried by one end of a rod 6, the central portion 7 of which is curved in a substantially semi-circular shape and adapted to support a cup or' other vessel 8 into which a beverage is dispensed and from which it is drun'k by the patron or purchaser, the opposite end portions of the rod 6 being journalled in opposite portions of a` transversely U-shaped casing 9, having an open side which registers with the opening 2 in the cabinet Wall 1 and a closed bottom 9. This same front Wall 1 is also preferably provided with an aperture 10 through which used cups are thrust after serving the function for vrlii ch they are designed, an L-shaped tube 11 heilig secured to said front- Wall in communication with the aperture 10 and being directed inwardly and downwardly so as to dis charge the used cups into a Waste container 12, removably positioned Within the cabinet and resting upon the lowermost wall 13 of the latter. It will also be noted that a drain tube 14 leads from the lowermost portion of the cup surroundingI casing 9 towards and so to direct liquid which may spill within said casing into said waste container.

Preferably, in the upper portion of the cabinet and adjacent to the rear wall 15 is a compartment surrounded by heat insulation material 16 and divided into two

sections

17 and 18 for the respective cooling of the carbonated water or other diluting agent and the syrup or other base from which the beverage is formed. The heat insulating material 16 maybe of any suitable type such for instance as cork, mineral wool. or the like, and it is confined between the rear wall 15 and the wall 19 of a shell which also comprises end walls 20 in spaced relation with the parallel side walls 21 of the cabinet and an irregular inwardly positioned wall Q2 in spaced relation with-a correspondingly shaped wall 23,

.extending across the interior ot said cabinet between the sides Q1 ot the latter, substantially as shown in horizontal section in Fig. 2. Access'to the compartment Sections 17 and 18y may be gained through one or more double walled closures Q4, including a layer ot' heatl insulating material 25. rlhe lower portion of "these compartment sections is closed by means oele a double walled bottom 26 also embodying a layer ot' heat insulating material 27. i y lllithinthe cabinet, thus described, there positioned'adjacent to the front wall 1 and above theaperture 2, any suitable form of cup magazine 26. adapted to support reserve cups 29 from which the lowermost cup 30 drops into the position shown in l, 2, 3 and 6 by any ,suitable type ot release mechanism actuated by ay lever 31, connected by means ot a; chain 2Q over a pulley 33 with variable positions 34 upon an actuating lever pivotally carried at 36 by a block 27 secured within and by the adiacent walls ot the cabinet and actuated as hereinaiiter described.

pening' through any suitable portion et the front. wall 1 is the receiving end 38 of a coin chute 39. which is provided al; any suit able pointwith a laterally curved portion 4l), having a 'laterally disposed elongated opening 41 adapted to permit coins ot sizes smaller than 'that for which the apparatus is designed to operate to tall from said chute into any desired position or receptacle. whence they can be removed by the one operating the device. @n the other hand. coins of the proper size or denomination continue downwardly through said chute until they pass therethrough and into any suitable {"orm ot receptacle Yl'rom which they too can be re,- moved by the owners or lessors ot the device. after sucn `coins have actuated the arm #l2 of a lever which is pivotally supported at 48 by any suitable medium. and also compri: a second arm 44 having a cutaway portion providing a shoulder 45, said lever being yieldingly maintained in its normal position with the irst arm 42 in raised elevation by means of a spring 46, the tension of which is adjustable in any suitable manner as for instance by means of the set screw 47.

Pivoted at 48 a lever having an arm 4f) which normally engages said shoulder 45, and a second arm having an angular shape so as to provide .a seat 50, in and against which rests a link 51. through the medium ot' an anti-friction roller 52. The lever arm 4f) is vieldingly maintained in its normal position by means of spring 53, while the link 5l. is maintained in extended relation with respect to the arm 5l ot a lever by which it is pivotally supported at by means of a .spring 56, carried by said last-named lever.

The lever arm 54 extends beyond a supporting pivot 57 and is integral with an oppositely extending arm 58. terminating in a flattened extension 59. through which extends an aperture 60 for a purpose hereinafter described. The arm 54 of this last-mentioned lever is provided with an L-shaped rest 61, upon which the lower free end portion of a rod 62 is adapted to move. but is prevented from moving beyond said rest in one. direction by a wall 63. the longitudinal movement ot said rod 62 being freely permitted, while its transverse movement is relatively limited by a bracket 64 through an aperture in which said rod slidably extends. Also. the lower portion ot said rod is vieldingly positioned` adjacent to the rest 61 by means ot a spring 65 carried by the lever arm the arrangement being such that when said lever arm is depressed. the lower free end ot' the rod (El) rides relatively upwardly and over the rest 6l so that the rod is moved upwardly as the lever arm moves in that direction, said rod. however. at a predetermined point in its upward movement being'removed trom engage` ment. with the rest 6l said rod engages one side of the aperture 64 in the bracket 64 4thrfnigli which it extends.

The oppositely extending lever arm 58 is provided with a laterally extending' pin 66 which is adapted to be engaged by a shoulder 67 ot a notched portion ot a lever arm 69. pivotally supported at 69. and provided with oppositely extemlinellattened and weighted portions 70 and 71 respectively. said flattened portion being in alignment with the aperture 60 in the 'flattened portion 5.() ot the lever arm 56 and in spaced relation therewith. Elaid lever arm 58 is also connected adiustably ".vith the. lower end portion ot a rod 72. while upon its l "tened portion .'f

and in axial alignment .th the a portare llt: is a spiral compression spring' 73. through which slidahlv extends a link 74 carrying an adjustably positioned nut or op 75 and supported by the lower end portion ol a niston rod 76. l

The exp-f 76 is provided with a laterally projecting arm 77 in alignment with and adapted to engage the actuating lever 35 to trip the latter and release the cup 30 from the inagazine 28 at a predetermined point in the operation of the device. Said piston rod is also provided with a laterally extending arm 78, said last-named arm as the piston rod rises being adapted to engage the diagonally directed tree end portion 79 ot a rod 80 which. ata suitable locality, is provided with an elongated slot 81 through which slidahly extends a pin 82 by which said rod is carried by a bracket 83, the uppermost free end portion of said last-named rod being ed to engage. the shoulder 85 of a reciprocat-orv rod 80. which in turn is connected to the stem 87 of a normally closed valve 88;

The piston rod 7 (passes into a cylinder 89 through a head 90 and is provided with a piston 91. which with said piston rod is normally maintained in its uppermost position against the stop 92 by means of a spiral compression spring 93 Surrounding said lastnanied rod within said cylinder. The upper portion ot said cylinder extends beyond the stop pin 92 and terminates in a closed end 94, provided with an air escape orifice 95, adapted to be closed normally by a suitable closure 3U 98, carried by a float 97, while the sides of said cylinder are provided with apertures connecting with inlet and outlet tubes 98 and 99, respectively, preferably a slight distance above the uppermost limit of movement of the piston 91.

Within the cabinet is removably positioned any well-known type ol tank 100 which is normally connected at 101 to one end of a coil ol pipe 102, positioned within the cooling compartment section 17, said coil communicating through a pressure-reducing valve 103 with a pipe 104, which leads through a normally closed valve 105, through a pipe 10G, to a T coupling 107 of a special construction, the valve 105'being normally closed by means ol a valve actuating stem 108, which is engaged by a suitably mounted bell riantY lever 109. which latter at its 'free end is oonnected with the rod 72, in turn adjustably connected at its lower end 72 with the lever arm t l lll-fi thin t e;

lili

second, cooling compartment section is positioned syrup tank, 'from winch leads a pipe 110, which communicates through a normally open valve 111 and through a pipe 11i? with 'that c et the rPIi'lJ i" lo TWf l beni, wjt

er por auove reierrct, there is positioned a e interior oi? the through the i, ithin said T ball valve 115i, wliich, 111 is open, is adaptthe entrance to said T trom the i vent syrup trom flow-- S41ed pipe instead oi passdiagonally directed at 84 to form a lug adaptto the pipe 100, said ing through said T and laterally therefrom into the cylinder 89. On the other hand, at aY later time in the operating cycle of the device. when the valve 111 is closed and the valve 105 is open, the pressure in the pipe 106 is operative to force said ball valve 113 upwardly so as to prevent the water within the pipe 100 under pressure from passing up- 'ardly into the syrup supply pipe 1-10, but instead directing said water laterally into the cylinder 89.

The valve 111 is provided with a valve stem 114 which is operated by a lever 115, having its outer end connected by a spring 116 to one end of a lever 117, in turn piv otally supported at 118 upon the bracket 83, the opposite free end ot said last-named lever being adjustably connected with the rod 62. The rod 80 also supported by said bracket is normally held laterally outwardly by means of a spring 119 in such manner that as said rod 80 is raised, its offset 84 engages the shoulder above referred to. 1t will also be noted that the lever 117 is yieldingly maintained in a predetermined position by means of a spring 120 connected with any suitable fixed point, and which last-named spring is of a different degree of tension than the spring 116, extending between the lever 117 and the valve stem actuating'lever 115 ot' the valve 111.

1n the operation ot this device, the respective elements as shown in Fig. 1 are in a position of rest and are set for the complete operation of the device. The pressure in the tank 100, when the latter is filled, is one hundred and titty (1K0) pounds to the square inch or thereabouts, tnough the effective pressure in the pipe 104 is reduced by the valve 103 to any desired extent as for instance to sixty pounds to the square inch. Ice or other suitable refrigerating medium is placed within the compartment section 17 so as to chill the coil 102, valve 10S, and adjacent syrup tank in the compartment section 18. The cup is not in position, though it is shown in dotted lines, but instead comprises the lowermost cup 30 suspended by and from the magazine :28. The valve positions are as shown in Fig. 7 and the syrup by gravity is assumed to have passed through the pipe 110, valve 111, pipe 112, and T 107 into the upper portion of the cylinder 89 above the piston 91 in its uppermost position` until the float 97 has risen sufliciently to close the air escape aperture. 95 and thereby prevent further syrup from entering said cylinder. i

l coin ot proper denoniination, as for instance a live cent piece, is inserted into the receiving end 38 of the coin chute 39, said coin in passing downwardly finally dropping upon the lever arm 4Q which it trips, with the result that the leve arm 4-9 is released by the shoulder 45 and the link 51 di'ops,4pe11nit ting the lever arm 51 to drop, and raising the lever arm 58 upwardly. The lower end of the rod 62 is thereupon received by the rest 61 and the pin 66 engages t-he shoulder 67 of the lever arm 68, the weighted arm 71 having simultaneously raised the flat-tened portion 70 of said last-named lever. The upward movement of the lever arm 58 raises the rod 72 and thus opens the water supply valve 105, raising the ball 113 to close the syrup entrance 112 at the upper end of the T 107. The pressure of sixty pounds or thereabouts within the line 104-106, forces the piston 91 downwardly to the position shown in Fig. 8, the piston supported arm 77 engaging the lever 35, which, through the chain 32, operates the lever 31 to release the cu 30 to drop into the position 8 supported by the centrally curved portion 7 of the latch rod 6. The nut or stop carried by the link 74 engages the spring 78 as the piston rod moves downwardly, thus storing pressure through the compression of said last-named spring and finally passes and extends through the aperture 60 in the lever arm 58 and engages the flattened portion 70 of the lever therebeneath, with the result that the shoulder 67 becomes disengaged from the pin 66, whereupon the compression of the spring 73 forces the lever 58 suddenly downwardly, so that the upward movement of rest 61 forces the rod 62 upwardly, tilts the lever 117 tensioning the spring 116 and closing the valve 111. Also, the lever arm 58 in lowering depresses the rod 72 and closes the valve 105, thereby stopping the inflow of the diluent such as carbonated water, or other liquid, under pressure, through the T 107 and into said cylin-- der 89.

The lever 117 also lowers the rod 86 and opens the valve 88, thus permitting the combined charge of water and syrup within the cylinder 89 to be ejected yby the piston 91 under pressure of the spring 93 inte the swirl cup 121, whence the mixed fluids pass by gravity through a discharge pipe 122 into the cup 8. The lever 117 in lowering the rod 86 permits the shoulder to be engaged by the notched end 84 of the rod 80, thereby holding the valve 88 open until'the beverage is delivered to the cup. The piston rod 91 in rising carried the projecting arm 78 upwardly and thereby, upon the ejection of the beverage, engages the end portion 79 of the rod 80, which releases the shoulder 85 and permits the valve 88 to close. This movement also permits the valve 111 to open and pass a second charge of syrup into the cylinder 89, the air therein escaping through the port 95, as the float, upon the cessation of the upward movement of the piston 91, drops with the outflow of the syrup upon the stop pin 92. Also with the reopening of the syrup valve 111, the ball 113 drops to its lower seat and permits the syrup to How into said cylinder until again arrested by the float closing the port 95.

As before mentioned, when a predeten.

mined quantity of beverage has entered the cup 8, its Weight tilts the rod 6 so as to raise the arm 5 free from engagement with the door frame 3, after which the purchaser is free to open the door and remove the filled cup from its rack. The door 3-4 is preferably returned automatically by a springhinge 123, or the like, to its closed position and after one hasconsumed the contents of the cu 8, the latter may be deposited through the ca inet aperture 10 and tube 11 into the waste receptacle 12. This operation may obviously then be repeated as many times and as frequently as desired and .until the supply of syrup and carbonated water or other diluent have been exhausted, after which they may be replaced and the operation of the device proceeded with as before described.
