SELECTIVE MIXING FAUCET.

Application filed January 13, 1925, Serial No. 2,181, and in Australia October 7, 1924.

This invention provides an efiective and conveniently operated machine for dispense ing those kind of beverages from the bulk which are composed ofsoda water and different flavoured syrups and said machine is adapted to be installed on a counter or the like. It is obvious that the reservoirs for'the soda water and the flavouring syrups may be connected to-the machine in any approved manner. The dispensing of the difi'erentflavoured beverages is effected by .the same handle, which latter, through a push plate, simultaneously operates the inlet valves for the supply:- of the soda water and the selected syrup.

In some machines made in accord with this invention I employ only that portion and those members which are requisite for the sole dispensing of the soda water.

An essential feature of this invention resides in the structural means and formation made and provided whereby the soda water at high pressure is directly fed from the bulk into an expansion or relief chamber formed there-for in the casing of the machine and in said chamber the soda water is given instant relief and expansion and its initial pressure is; thiereby effectively broken up and reduced to enable it to flow at such approved and reduced pressure into the drinking glass through the outlet of .the chamber-said outlet having a greater transverse area than the transverse area of the inlet for the soda water. The soda water upon its entry into the said expansion chamber strikes against the front in ner wall of the latter and said wall is'preferably formed with an overhang shoulder whose object is to prevent undue upward splash of the inflowing soda water which would otherwise baflle the entry of the selected syrup into the said chamber and soda water.

angle and I do not limit or restrict myself to the exact or precise angle of alignment of said inlet and outlet. The structural features and use of the lnvention will now be described with the aid of the attached drawings wherein Fig. 1 1s a sectional elevation showing the op erative members in their idle position, the respective valves being closed. In said view for sake of clearness one syrup valve is shown and the working'position of the hands is indicated by broken lines. Fig. 2 is a front elevation of same.

In this specification the. description of the construction andoperation of a selected syrup,.valve and its related parts is also applicable to each of the plurality of syrup valves.

Beferring to said drawings, the invention comprises a casing as w'a adapted to be installed on a standard bracket or other like anchorage as a This casing may be made in one integral piece or made in two portions as a and a as shown in -which latter case the front portion at, is

made with a rear stem at adapted to pass through the rear portion a of the casing and be thereat secured by lock nut a further said portions may be secured together by holding flanges and studs as a Within said casing are housed the inlet valves for the supply of the soda water and the plurality of syrups or flavouring essences.

Within this casing. a-a is formed the chamber 72 whose throat 6 acts as the outlet for the beverage said chamber providing relief or expansion for the high pressure soda water upon its entry thereinto from its bulk container (not shown). The inner *front wall of said chamber is made with an overhang shoulder 12 which minimizes any upward splash of the inflowing The soda water is led from its container by pipe 6 to said chamber I) the inlet for same being controlled by the horizontally operative valve 0 of a selfsealing type which works in its seat 0 formed in the rear portion a of the casing. The stem 0 of said valve 0 extends forwardly and is formed therein with a duct or passage 0 which allows of the entry of air to destroy vacuum in the chamber 6 erative spiral spring f said spring 1s to retire said platefrom conas soon as the beverage is dispensed and the handle returned to its idle positlon as seen in full lines in Fig. 1.

During the dispensing action the push plate hereinafter mentioned when 1n its operative position seals this duct 0 and prevents any outward escape of liquid. On

the front portion of the valve stem 0 is secured a cap 0*, which is guided and held within a cavity 0 formed therefor 1n the portion a of the casing, sa d cap 0 being fitted with an internal spring 0 whose duty is to return the soda water nlet valve to its closed position as seen in Flg. 1. The plurality of syrup valves as (Z are also of a self sealing type and work in sea-ts d formed on the rear portlon of the casing and have forwardly extending stems n? which at their terminals are fitted wlth caps d held within cavities (Z formed therefor in the front portion a of the cas ng, said caps being also provided with splral springs (Z which operate to return the valves d to their closed position as shown in Flg. 1.

The cap of each syrup valved 1s fitted with a screw threaded adjustable plug 03 in order that the opening of said syrup valve (5 may be retarded or advanced relatively to the opening of the soda water valve to vary the flavour of the beverage.

The rear casing a is made with a plurality of passages as 6 each of which by plug controlled pipe as e communicates "with a syrup reservoir each of said passages 6 being provided with an upper and rear removable plug as e to allow of the cleanlng and rcplacen'ient of a syrup lnlet valve as d. From each of said passages 6 any selected syrup is led through the valve controlled inlet into a cavity a and thence into the central or mixing chamber 6. The front casing a is formed with an outwardly extending fixed stem f on which is freely and slidably carried a push plate 7 approximately of semi-circular shape. Said plate 7 is made with a boss 7 and provided with a rear op- The function of tact with the cap as c' and inset plug d of the respective valves as soon as the working handle 9 is returned to its idle position as seen in full lines in Fig. 1. The front portion of the boss f of said plate 7 is made with two flat or nut faces as Seen in Fig. 2 to receive and be operatively engaged by the jaws g of the handle 9 whereby the desired degree of rotation is given to said plate. This plate 7' is made with the projecting lug g to contact with the adjustable plug (1 of the selected syrup valve, said plate simultaneously having contact at a lesser radius with the cap 0 of the soda water valve.

To dispense soda water alone the plate 7 is sufliciently rotated to bring said lug 9' beyond the lowest positioned syrup valves at either end of the casing and as shown in broken lines in Fig, 2. The handle. g is pivoted to a block le by a pin 70, the said block being freely held on the fixed stem f by cotter pin is and fitting closely between the front of the handle 9.

The jaws g are eccentrically positioned with relation to the hinge pin and have cam shaped faces an which are adapted to engage and exert an inward pushing movement on the slidable plate f.

The operation of the machine in connection with a soda water inlet valve and a selected syrup inlet valve is as follows then the handle 9 is moved block 70 on the fixed stem 70 the desired degree of rotation necessary to bring the projecting lug g of the plate 7 immediately in front of-the adjustable plug 03? of the selected syrup valve d, the said handle 9 is then pulled outwardly, to the position seen in broken lines in Fig. 1 on its pivot pin 70, thereby causing the cam faces m of the jaws g to effect inwardly pushing contact against said plate f which in turn makes like contact at a lesser radius against the cap a of the soda water inlet valve 0, said plate b its lug 9 having like pushing action against the adjustable plug d of the selected syrup valve d. By the operation of the parts just specified, the valves (Z and 0 permit a simultaneous supply of the soda water and syrup from their respective containers into the expansion and mixing chamber Z)the beverage flowing through the throat 6 into a glass 10. As soon as the handle 9 is returned to its normal position the faces m of the jaws g are released from contact with the plate 7, the latter being returned to its normal position by the spring f as shown in full lines in Fig. 1.

What I claim as my invention and desire to secure by Letters Patent is 1.
