My invention relates to apparatus for dis- I pensing liquids such as root beer, birch beer,

cream ale, etc. which, either because of the tendency. to foaming due to 'the high pressure.

under which they must be vended or because of the condition of high fermentation as with ale, cannot be drawn and served directly from the' package, tank `or receptacle in which they are stored. lf the liquid be drawn directly from the tank, it is necessary to -wait a long time for the foam to settle so as to secure a sufficient body to form a salable drink, while on the other hand, if the liquid be drawn o5 into a secondary receptacle and left there for a long time so as to settle into a completely -solid condition, it will,

if not soon used, become stale.

The object of my invention is to provide an apparatus of cheap and simple constructionand capable of'rnore ready adjustment and uniform action `than previous forms of vapparatus designed to dispense liquid from a source of charged liquid supply in y two streams by the use of a suitable double draft dispensing faucet, still liquid reservoir and connections direct from the faucet to the charged liquid supply and from the still. liquid reservoir on the one hand to the faucet and on the other hand to the charged liquid supply.

To this end my invention consists in the special combinations of apparatus herein after more particularly described and then specified in the claims. y p

In the accompanying drawings, Figure l is a general vertical section and side elevation `of an apparatus' embodying my invention,

the dispensing faucet being shown in side elevation. form of float controlled valve that may be used for the settling or expansion chamber.

Fig. 3 is a vertical section through a form of7 dispensing faucet which l prefer to employ. Fig. 4 is a general plan of the same showing the relation of the various ports to the disk therein and to the pipes, leading through the shank' of the faucet and adapted. for connec- Fig. 2 is a vertical section of a tion with pipes leading from the settling or expansion chamber and the tank or package containing the charged liquid. Fig. 5 is a horizontal section taken on Athe line 1 1, Fig., 1.

In the preferred form of carrying out my invention, A indicates the outer casingof the apparatus which may be of wood or any other suitable material and in the form of a barrel orfin any other suitable form.

B indicates an inner casing supported on the bottom of the outer casing A. and separated. from the main body portion of the outer casing by a closed air space surrounding the innervcasing B.

C indicates the reservoir containing the liquid in a still condition supported within the upper portion of the inner casing B and separated from the inner casing by a space in which the ice for cooling is stored.

P indicates a double draft dispensing faucet of any suitable character having connections direct to a storage tank or receptacle G containing the charged liquid and to the still li uid reservoir C, the latter being on the ot er hand connected also to the charged liquid. su ply G through an automatic valve controfled by a float and adaptedto replenish the contents of the still liquid reservoir, as will be hereinafter more particularly described. The dispensing faucet F is of suitable character for dispensing liquid directly 'into a "drinking glass or mug and may be made as hereinafter more forth.

H indicates 'a pressure reducing and regulating valve interposed between` the charged liquid supply G and a conduit which passes up through the bottom of the casingA as shown, the conduit being elongated and coiled to form suitable coils E and connects with a 'lV-joint or coupling markedF. From the `latter a branch pipe or connection j' is carried through vthe walls of ythe inner and particularly set outer casings to the faucet and another branch i or connection to an inlet valve I which controls the fiow 'of the liquid from the charged liquid su ly G into the still liquid reservoir C.

The coils E are preferably supported in the space below the still liquid reservoir C, which constitutes-a cooling chamber, by means of a platform secured to the inner casing B somewhat above the bottom ofv the louter casing and forming a supplementary bottom for the .casing B. This refrigerating chamber 'is 1n communication withthe ice storage space tim) between the inner casing B and reservoir C so that the iced water-from the ice storage space will flow into this chamber and surround the conduit D entering the chamber, the coils E and its branches located therein and also envelop the lower part of the reservoir C. As iced water is a better cooling agent than ice itself, all the liquid would remain in a cold state by the use of a compara tively small amount of ice. A suitable over-k flow drain pipe might be used as indicated at Q so that the iced water vwould notl run olf until it had reached a desired level above the liquid in the reservoir C.

M indicates the mouth of the valve l through which the liquid fiows into the still liquid reservoir C, its flow being controlled aun tomatically by the action of a float li. rlhe float L is attached to the arm K by a rod which may be secured in any position on 'said arm by means of a'set screw L to thereby vary the height to which the liquid may rise in the reservoir before the valve shall shut ofi' the flow from'the charged liquid supply G. As shown, the dispensing faucet is located just below the level of the outlet from the reservoir and so that the liquid discharging i from said reservoir under slight liquid head will not be caused to foam excessively in the Aact of passing through the valve-passages and outlet.

O indicates the pipe forming a still liquid .outlet from the reservoir C passing referably through the cooling chamber and t rough the walls of the inner and outer casings and across the space between them to the dispensing faucet located outside the casing A. The outlet O makes connection with the liquid in the reservoir C preferably through the bottom thereof and is of such size as to allow the liquid to flow with comparative freedom. By this construction all the liquid may be drawnfrom the reservoir C and without ex cessive foaming.

The preferred construction of the valve l is more clearly shown in FirJr 2. A stem j of 'the valve worksfin the outlet pipe M and is yprovided with a laterally extending pin or pins m for engagement by a hook or extension forming the short arm of pivoted lever K, so that when the float L falls, the stem of the valve will be lifted and liquid permitted to flow from an expansion chamber insaidl valve through the outlets of the valve and into the still liquid reservoir C; The conneqtionof pipef with'the valve body is made N is a suitable adjusting or throttle valve interposed in the connection from f2 to the valve that controls the escape of `liquid through the outlet into reservoir C. By means of this valve the size of the passage 'through which the liquid is supplied to the reservoir may be regulatedvto adjust .or

f vary the flow into the reservoir according in the disk.

sans is to the demand made upon the temporarily accumulated quantity of still liquid by operation of the dispensing. faucet. When the liquid is drawn off more frequently from the reservoir, said valve is opened slightly so that a larger lstream may besupplied to the tank, but as will be obvious the pressure under which said larger stream flows will be the same as with a smaller stream, and

hence there will be no increased tendency to foam in the discharged stream discharging into the reservoir and no excessive foaming therein beyond the capacity. of .said reservoir operating as a settling tank. If on the other hand, the demand at the faucet is small, the valve N may be adjusted to curtail the flow. By adjustment of the float the average amount of liquid stored temporarily in the reservoir may be regulated, so that the height of 4liquid' therein. shall normally stand at a' higher or lower level according to the maximum probablev demand ma'de on the contents of the reservoir by the operator. As will be seen, no practical variation of the head under which the liquid is drawn -from the reservoir will be introduced by these adjustments and under ordinary conditions the liquid will flow out of the reservoir without being subjected to any pressure of gas from the original supply source, whereas in some previous constructions of apparatus employed for a similar purpose not only is it necessary to employ pressure upon the surface of the liquid in the tank used as a settling tank in order to force it to the. higher level at which thev faucet is situated, but the construction necessitates also a pressure which varies with the demand and likewise varies as the level of the li uid falls nearer to the outlet from said ta r through which the liquid passes to the dispensing faucet..

The dispensing faucet in its preferred form comprises a disk W turning on a seat X and' provided `with a suitable operating handle connected. to the stem on which the disk is secured. The seat X is preferably made or provided with some compressible substance in which annular sealingrings on the face of the disk W will impressi-filiera selves, said annular projecting rings'including between their two circumferences an annular space in which includes the several ports disposed in the circumference of a circle in the seat X. The disk W hasin its face ports c', ai connected by a channel b in the face thereof opposite the valve seat X and are of the same or somewhat larger size than the lower lpair of portsv C which pass through the valve seat A and witl which the ports ai', may be' brought into simultaneous-registry by turning the valve to proper position; One port c opens into the lower chamber Y in the spout of the The ports or openings care essere under pressure is drawn from the package' or tank G.

By placing the channel t in connection with the ports c', c of the valve seat X, a i full free stream is secured from the reservoir y C through the outlet pipe @passing along the shank ol the faucet P By placing the channel l) in connection with the ports e', c, a Vtinestrean'i oi high pressure is secured from the main supply through the branch pipe j" passing along the shank of the t'aucet l). By placing the diskchannel b with the ports c, a at the position shown in Fig. l the valve is closed. By locating the ports c', c and e, e at the proper distance apart, no stop is required for governing the disk W for at no time can the channel b form a connection between the channel supply pipes and this absence of a stop greatly lengthens the Wear oi" the faucet. This faucet P is supplied with the usual adjusting sleeve and lock. nut permitting a continual tightening ci' the valve should it leak.

The s out ol' the faucet is an open cham-I ber Y, t e delivery port c for the liquid under lovsT pressure opening directlyinto it to facilitate a free liovv, While the delivery'portl c has a very small pipe Z attached, this pipe Z extending to the bottom oi1 the spout cham-y ber Y, thus instr-ing a steady stream under high pressure to he directed into the receptacle, a glass or mug.

rl`he operation of the apparatus follows: At rest, With the apparatus empty, the ports af", a of the disk W, of the faucet are at a point Where the vfaucet will be closed, While vthe reservoir C being empty, the float L is pendent in the tank C. rlhe adjusting valve N having` previously been tested and set at a point that will prevent the overflow of the reservoir C by reason of an excess of foam, the apparatus is noviT connected to a tankof root beer for instance, under lhs. i ressure, andthe 'lloW turned on. The liquid `will pass through the conduit to the supply Fixture F where it divides one stream passing to the faucet l? at c, the other to the valve l whichlis open and into the reservoir from gentle, though copious, discharge although the initial pressure is 120 lbs. W hen a suilin cient quantity has entered the reservoir C -and has settled, the iioat L rises and closes the valve l. The initial test of the apparatus determines the proper point at which to set the valve hl so as to permit the liquid faam to settle into solid and operate the loat l; to lclose the valve l ifvitho'ff l excess oi foam .lioiv c voir (l and thereby turning the disl` J nects the se large diante. from the reserY to the faucet, 'thi g L channel t', into the spout (arcani thence into the serving glass. the glass ha ig heen lille( f a" are placed in connectie. i gne ports e, c', and these latter being et very small diameter, a vline stream under high pressure will i'lovv along the pipes to thefaucet P througl'i the ports c, c and continuing through the outlet pipe Z, will deliver a highly charged and foamy liquid directly into the liquid already in the glass, imparting to the Whole drink a sparkling condition. The ccntents of the reservoir C being lowered, the dropping of the float L opens the valve l, replenishing the contents, and ifbut one drink be drawn, this' inflow is very slight, as the ull filoat L is very sensitive and acts imniediso that it is physically impossible to draw and serve drinks so often but there will always he solid liquid in the reservoir. li, for

any reason, it may become desirable to dispense 'the contents so as to empty the reservoir C, the throttle valve N may he set so as to lclose the valve l permanently, preventing a further inliow to the reservoir C, even though the float L drops, While still affording a'supply to the fine stream under high pres'- sure through the branch f. rlhis might cccur near the close of a day-s business. 0n a cool day, or under any circumstances where a smaller supply is desirable in thereservoir C, the lloat L may he lowered to any point by adjusting the set nut on the supporting rod, this arrangement permitting the adapting of the apparatus to a large or small volume of vending.
