UNITED STATES PATENT OFFICE BEVERAGE FAUCET J oseph G. Giuliano, Detroit, Mich.
Application December 8, 1945, Serial No. 633,613
10 Claims. (Cl. 27760) This invention relates to faucets and more particularly beverage faucets.
An object of the invention is to adapt a faucet to selectively discharge any of several beverages, thus greatly facilitating service of mixed drinks and largely reducing the equipment required for dispensing a variety of beverages.
Another object is to provide a faucet in which preselection of a beverage may be effected without inducing actual flow, so that for several consecutive servings of the same beverage, one setting of the selector suifices.
Another object is to provide a faucet adapted to effect a mixture of carbonated water with a beverage in a suitable proportion.
Another object is to provide a faucet suited for selectively serving several beverages, and providing for a rinsing out of its flow passages preliminary to resetting the selector.
These and various other objects are attained by the construction hereinafter described and illustrated in the accompanying drawings, where Fig. 1 is a side elevational view of my improved faucet as mounted for use.
Fig. 2 is a longitudinal vertical sectional view of the same.
Fig. 3 is a front view of the faucet.
Fig. 4 is a cross sectional view taken on the line 44 of Fig. 2.
Fig. 5 is a cross section taken on 5--5 of Fig. 2.
Fig. 6 is a cross section taken on 6-6 of Fig. 2.
Fig. 7 is a perspective view of the aligned stems of the faucet and a lever for reciprocating one thereof.
In these views, the reference characters 2 and 3 designate respectively a front, an intermediate, and a rear casting, jointly forming the faucet casing and rigidly interconnected by four elongated screws 4, having threaded rear ends set into the casting 3 and heads 4a recessed in the front face of the casting I. Integral with or otherwise rigidly connected to the casting 3 is a tube 5 forwardly projecting axially of the faucet and snugly fitting in the castings 2 and to accurately maintain their proper alignment. Slidably and rotatably fitted in the casting 3 and tube 5 is a primary stem 6 whose front end portion projects beyond said tube and into a cylindrical chamber 1 centrally formed in the casting I, said stem having an enlarged annularly grooved head 8 within said chamber. Straddling said head within the groove thereof is the forked lower end 9 of a lever H] for reciprocating said stem. Said lever is accommodated within a slot II of the casting and pivoted on the casting by a pin l2 transverse to the faucet. A ball l3 or other suitable handle surmounts said lever.
Aligned with the stem 6 forwardly thereof is a relatively short rotative stem l4 having :an actuating knob |5 fixed thereon by a set screw I6 close to the front face of the casting I and having on its rear end an enlarged head abutting the front wall of the chamber 1. Thus the knob I5 and head ll jointly restrain the stern M from any material reciprocation. The heads 8 and H are normally closely adjoining and are interconnected for rotation in unison by fitting a tongue IS on one thereof freely within a diametrical slot IQ of the other (see Fig. '7) A pointer 20 radially projecting from the knob l5 provides for indexing the knob with respect to a circular series of numbers or other differential indicia 2| on the front face of the casting As illustrated, these numbers are carried by plugs pressed rigidly into .sockets in the supporting cast- The casting 3 has an enlarged rear portion 22 formed with a circular chamber 23 receiving an arm 24 fixed on the rear end of the stem 6 and a cover 25 for such chamber is secured in place by bolts and nuts 26. Rigidly mounted in the cover 25, coaxially therewith is a circular series of tubular, rearwardly projecting valves 21, euuiangularly spaced and equal in number to the index points 2| at the front of the faucet, and a like valve 28 is carried by the cover at its axis, said valves being preferably screwed into the cover. Centrally slidable in each valve is a stem 29 rigidly carrying a valve member 3|! urged forwardly to its seat by a coiled spring 3|, an unseating device for said member being formed by a forward portion of the stem projecting into the chamber 23 sufiiciently to just clear the rotary path of the arm 24 when the latter is in its normal position against the front wall of said chamber. This position of the arm is maintained by the lever l0, when upright and is further normally maintained by the stem 29 of the central valve 28. To the rear end of each valve 21 and 28 a beverage pipe 32 is connected by a coupling 33, and a pipe 32a is similarly connected to the valve 28, said couplings forming abutments for the rear ends of the springs 3|. Each valve is formed with a restricted beverage passage 34 serving as an inlet to the faucet and controlled by the corresponding valve member and discharging into the chamber 23. Opening from the chamber 23 at its bottom is a beverage outlet 35 leading through the castings 3 and Z to a spout 36 formed as an integral downward extension of the casting 2.
The described faucet may be supported in any 3 desired manner, there being illustrated a supporting collar 31 screwed on the front end of the casting 3 and attached by screws 38 or the like to a wall 39 apertured to receive the faucet.
In use of the described faucet, the pipes 32 are connected to supply sources for different beverages, and the pipe 32a to a source of carbonated water. To draw off any one of the available beverages, it is necessary merely to index the knob [5 with the number 2| corresponding to such beverage and then pull the lever [0 forward to its discharge position shown in dash lines in Fig. 2. Rotation of the knob registers the arm 24 with the stem 29 of the valve controlling the desired beverage, since the stem 6 carrying the arm is interlocked with that carrying the knob by the tongue [8 and groove l9. Forward'actuation of the lever l0 shifts the stem 6 and arm at rearwardly to retract the stem 29 wherewith the arm has previously been registered... It is to be noted in this connection that the tongue I8 extends sufficiently into the groove, 19 to avoid escape from such groovein the retracted position of the stem 5. When the arm 25' is rearwardly shifted to open one of the valves 21',- it also opens the central valve 28 since the stem of the latter is constantly registered with the pivotal end of the arm, and consequently the discharge of any beverage into the chamber 23 is accompanied by a discharge of carbonated water. Thus the faucet serves for carbonating beverages as well as selecting them and, regulating their discharge. It is evident that the arm 24 functions as a control element for the several valve members.
Obviously such a faucet greatly reduces the necessary amount of equipment for a soda fountain or bar and largely-reduces the space required for an installation dispensing numerous beverages. 7
It is a desirable feature of the construction that in event of two or more consecutive orders for the same beverage, service maybe given without repeated indexing of the knob [5. It is'also highly desirable that the chamber 23 and passage therefrom to the spout may be rinsed out between withdrawals of any two 'diiferent beverages by establishing a momentary flow of carbonated water alone. It is to benoted in this connection that any adjustment of the knob 15 such as to locate its pointer substantially midway between two of the dial numbers 21, will adapt the arm 24 to be retracted between two of the outer stems 29, such retraction therefore beingeifective only on the stem of the central valve 28, controlling carbonated water.
' A faucet as described will'greatly facilitate the serving of mixed drinks, permitting desired quantities of each ingredient to be drawn from the same faucet, the necessary indexing being very quickly accomplished.
What I claim is:
1. A faucet comprising a casing having front and rear ends and having'a liquid flow chamber in its rear end with an outlet therefrom and a substantially circular set of inlets thereto, a plurality of valves respectively controlling the respective inlets and each having a stem forwardly projecting'into said 'fl'ow chamber, a primary stem rotatively and reciprocably mounted in said casing and forwardly extendingfrom said chamher, a control element fixed on the'primary stem within said chamber forwardly of said valve stems, rotatable by the primary stem for selective registration with said valve stems, andreciprocable by the primary stem, to actuate a registering V chamber having a fluid outlet and further having a plurality of fluid inlets disposed in a substantially arcuate series, valve members respectively controlling the respective inlets, a control element for said valve members pivoted at an axis about which said arcuate series of inlets is substantially centered, and reciprocable along said axis, means includingan actuator for rotatingsaid control element about said axis to register such element selectively with any of said valve members, means .includin an actuator for shifting said control element along said axis to unseat any valve member with which said element is registered, and a mixing valve member registered with saidcontrol element in all rotative positions of such element and-opened by actuation of such element along its axis, in any of said positions, the valve members forming said arcuate series being adequately spaced to afford a reciprocation of said control element between said members, whereby the mixing flow valve member may beactuatecl independently of the other valve members, each of said actuators being static while the other is being actuated 4.
