LIQUID-DISPENSER.

Application filed. November 26,1915. Serial No. 63,509.

To all whom it may concern:

Be it known that we, WILLIAM HENRY" JOHNSTON and HENRY JOHN VVILLIA s, citizens of the United States of America,residing at New York city, in the State of New York, United States of America, have invented certain new and useful Improvements in Liquid-Dispensers, of which the following is the specification.

This invention relates to dispensing, mixing Or serving apparatus for liquids or the like and general obj ect of the inventionis to enable an exact proportioning, effective mixing and an aeration of a plurality of liquids to be Obtained. The invention is particularly useful or effective to the mixture of a syrup or concentrate in given proportion with water orother suitable liquid.

In this type of apparatus it is important that exact proportion should be maintained between the syrup and water, and that an 3 effective mixture and aeration should take place before the mixed ingredients are dis charged in the formof the finished drink.

Still further object of the invention is to provide such a typeofdevice as maybe readily combined with heating or cooling means in order that the drink to be served therefrom, may be hot or cold as desired.

The invention comprises, generally stated a mixing chamber, means for supplying proportional quantities of liquids thereto, and

producing a swirling mixture therein, means for dlscharging the IIllXGd product under pressure in such a manner as to effect aeration. For complete understanding of the invention, however, reference is made to theaccompanying specification and drawin s. In the drawings, 3

igure 1 is a sectional elevationof an embodiment of the invention.

Fig. 2 is a sectional detail through the measuring cylinders.

Fig. 3 is a plan of the measuring cylinders. i

Fig. lis a sectionalview of one form of nozzle. fl

Fig. 5 is a sectional detail" of an alternative form of nozzle.

Like characters ofreference indicate corresponding parts in all figures.

Referring to the drawings, A represents a casing adapted to contain the principal working parts and also to contain means for which it is heating or cooling the beverage served. In the embodlment illustrated the device may be used as a cooler and ice maybe placed therein, the ice water being drained through a sultable outlet cook 11 B represents the container for the syrup or concentrate and C the container for the water which is to be mixed therewith. These so that they may be fed in uniform proportions, a barometric feeding arrangement is I Specification otLettersPatent. P te t N0 30,

containers are conveniently in the form of in- *verted bottles and in rder to secure uniprovided, consisting of wells 12 and 13 into which the necks of the bottles B and G extend, the said necks extending through the top 14: of the casing and being supported thereby. It will be obvious, however, that other suitable means of support for the bottles may be provided.

From the wells 12 and 13 the liquids and syrup are adapted to pass by conduits 15 and 16 to the cylinders D and E, which are conveniently cast togetherand arranged in co- 3 axial relation as shown. The conduit 15, from the well 13, which supplies water from the container 0, leads through the cooling chamber F and maybe surroundedby ice Said conduit 15opens into a port part of the cylinder D. The conduit 16 therein, and may also beextended to any desired extent in order to securethe requisite cooling.

17 in thejconstrictedneck 18 on the upper opens into the port 19 formed inthe constricted neck 20 at the top Ofthe cylinder E.

The diameters of the respective cylinders D and E correspond with the proportion in desired to mix the syrup and liquid? a Cooperating with the cylinders are plungers G andH which in the embodiment illustrated are formed integral with each other. The smooth outer surface of the plunger G fits the smooth inner surface of; theneck 20,

while the smooth outer surface of the plunger H fits the smooth inner surface of the "neck 18. Escape of any liquid from the cylinder D is insured by a "suitable packinlg t gland 21 at the top. of the cylinder. will be observed that asthe plungers fit the necks 18 and 19, whenthey are in innermost position 3113111111181 space will remain between the plun ers, and the walls of the cylinders, and rom these annular spaces,

. This arrangement ha's'an effect of producing a swlrling motion ofliquid in the chamber K, which will thoroughly mix the constituent parts of the: liquid.

Fromtheoutlet 25, a conduit 26 leads to a discharge nozzle 27. This nozzle is designed. to effect aeration of the product, Which is accomplished by forming a plurality of .fine orifices 28 in the nozzle,

- charged under pressure.

through which the mixed liquid is dis- In the form of nozzle shown in Fig. 5, the fine streams from the orifices are combined by a tapering nozzle member 2,9..and" discharged through the orifice 30 in. a fine stream. Should it be desired to heat the liquid instead of cooling it, an electric or other form of heater L of .well-known design may be attached to or combined with the conduit 26.

The pistons G and Hmay be operated b [any convenientmechanism. As shown, an vopera'tlng lever M'is pivoted to a bracket '31 on the casing and has a link 32 pivoted "near the'end to the same, the opposite end of the link being pivoted to a bracket 33 on the interior of the piston H. V

If desired a suitable-counter N may be provided; which will be operated by the movement of'the link 32 and by which the number of drinks-served by the dispenser may be indicated in a well-known way.

.Tonpreventtheproducing of a vacuum in thecylinder D, an air vent in the form of a msmall conduitO/maybe provided leading from the upper part of the cylinder.

' In operation the containerB-is filled with the syrup orconcentrateand the container Cisfilled withsthe water, with which it is 'to-be mixed. The apparatus is designed for usewith a variety of syrups and liquids. -'I}hewaterfmay be charged with carbon dioxld or not, and the apparatus might even .Jbe'used tomixpastes or-semi-plastic sub- --:S C

1 Thef-normal position ofthe plunger is the raised;positionshown in Fig. 2. It will be "seen; that in --this' position both cylinders D Land E-willbe ,fill'ed by gravity from the containers.B and C. The barometric feed arrangement insuresuniform, atmospheric -.pressure. 21A pressure feed might however "be used if desired.

. Whenit isdesired to serve-a drink from I Qthe-apparatuathelever M is operated in a .downward direction. forcing both plungers downwardly; This movement will at once .eut.ofi th mrtsaflwand. =19, preventing any further flow of liquid or syrup. The continued movement will force the li uid and syrup contained in the cylinders and E through the ports 23 and 24: into the mixing chamber K. Owing to the fact that the liquid and syrup are introduced from the bottom and at one side of the mixing chamber a swirling motion will be produced therein which will effect the mixing thereof.

The further downward motion of the lever will assert a. pressure on the mixed liquid forcing it through the conduit 26 and discharge nozzle 27, under pressure. This will result in the production of a plurality of fine streams, which immediately 011 leaving the nozzle will absorb a quantity of air, thus giving the desired aerated eilect to the drink finally produced.

The amountof pressure which comes from the degree of aeration may be regulated by the pressure on the lever M. It will be observed that the liquids are not only mixed under pressure; but that they are also discharged under pressure. Immediately on raising the plungers G and H on the return movement of the lever M, water and syrup will flow into the cylinders D and E under gravity.
