To @ZZ whom it may concern.- Beit known that we, JOH J. FITZGIBBON and JOHN M. TRAVIs, citizens of the United States,residingat St. Louis, State of Missouri, have invented certain new and useful Improvements in Faucets, of which the following is a full, clear, and exact description, `reference being had to the accompanying drawings, formlng a part hereof. v

'lof lOur lnvention has relation to improvements in faucets for carbonated beverages; and it consists in the novel details of construction more fully set forth in the specilication and pointed out in the claims.

In thedrawings, Figure 1 is a combined vertical section and elevation of the invention, the section being on the line 1 1 of Fig.

... Fig. 3 isa 3 3 of Fig. section Fig. 2 is a top plan thereof. transverse vertical section on line 2. Fig. 4 is an enlarged combined A and elevation of the valve controlling the syrup-discharge, and Fig. 5 is a bottom plan view of the operating-lever.

The present invention is a modification of the constructions of faucet shown and de-V scribed in our United States Letters Patent 785,869, dated March 28, 1905, and in our pending application, SerialNo. 254,553, led April 8, 1905, and while contemplating the several advantages of the aforesaid construc-n tions the present-device is materially simplified, being in a measure more compact, cheaper to manufacture, and more quickly dispensing the beverage which it is designed to serve. s 11p-receptacles are materially reduced in t at they are no longer depended on for serving measured quantities of the syrup, the latter flowing into and 'filling the receptacles from their respective sources of supply as fast Vas the syrup is withdrawnthat is to say, as long as the valves are in an open position. In the present faucet special provision is made against leakage of the syrup out of the chambered-portions of the body portion, such provision consisting in yielding rubber diaphragms coupled to the reciprocating valve-stems, which pass centrally through thedchambered portions or receptacles aforesai g The faucet consists of other qualifications, whose advantages will be better apparent from a. detailed description of the invention, y

which is as follows:

Referring to the drawings, C represents a suitable casting or body portion, the same In the present modification the chamber is closed by ent case) of chambersor rece tacles 1 1for the influx of syrups, said cham ers bein -disosed on opposite sides of the center o the ody portion, as shown. The top of each a screw-cap 2, below which is dropped a rlng 3, which is forced by the screw-cap vagainst the edge of a. yielding rubber diaphragm 4, bearing onV the shoulder or annular seat 5, formed above the syrupchamber. In this way the edge of the diaphragm is forced against the seat 5, forming a water-tight joint-therewith and preventing the syrup entering the chamber or receptacle from leakin out at the top.

The diap agm is provided with a'central opening for the passage therethrough of the valve-stem 6 .of the syrup to which the stem is screwed', Fi 4, the edge of the diaphragm-opening closing over the valve-stem beneath the terminal head 8 of such stem, when by screwing the stem fully into the valvethe diaphragm becomes snugly and tightlygrip ed between said head and the 'loosely-enve oping sleeve 9. The vdiaphragm being of rubber of course stretches as the head 8 isinserted through the opening thereof, after which the moment the head has passed fully through the opening the edges of.

the latter close snugly over the stem 6, when -discharge valve 7,

being provided withi series 1(two in the presthe connection as described is effected. This central connection likewise makes a tightA joint at this point. The valve 7 is forced against its seat 10 by the spring 11 ,confined in the cavit 124 and resting on the plate 1.3, formed wit 'the discharge-nozzle 14, said plate being secured, by means of screws, to the body portion of the faucet.

Entering each s p chamber or receptacle 1 from the rear 1s agfeedassage 15, into which the syrup is conveye 16, leading to any source of syrup-supp y, (not shown,)l and leading from the chamber at a point below the passage 15 at substantiall ninety degrees removed therefrom is a disclararge lpassage or opening 17, normally closed by the valve 7, but which upon a proper depression of the valve permits the syrup to discharge into the central waterdischarge passage 18, which communicates directly with the passage of the nozzle 14. Directly behind the passage 18 is a chamber 1, with which communicates the carbonated water-supply ipe 19, leading to any source of sup ly. (lgot shown.) This chamber is normally closed by a valve 20, the latter bc- IOO , Y. chargefpassage 24 throu Q the passage. 18am ,.5

A` the passage 18, whence it enters the nozzle f nates in a' .central g forced to its seat` by a spring 21,*confined wi hin the chamber, one end of the spring bearin 'against the valve andthe op ositev end being received by a cu 22, screwe into thel base of the chamber t e plate lbeing formed .vith a suitable depression or pocket "to snugly close over the projecting head of g L 'the cup 22, Fig. 3. i?, with afstern or plunger 151.0

`valve intofthe space 24, and finally into thence into' the passage 1,4. The upper end of the valve 23 termistud 26, over which is passed a cap 27, which may be renewed from time to timeas the same wears away.

The several valves (or rather their stems,

i' `vvhichfor all intents and purposes must be cam formations 28 29,

.2, the cam formations 28 29 Wi 'considered as parts of the valves and which are designated as stems only hy reason of their reduced dimensions) proiect beyond the top of the body portion C., said projecting the paths. of suitable disposed. on the under side of the short arm of the operating lever or handle 30, the same as in our pending application aforesaid. In the present case the ever is likewise connected to a rotatable stem or post 31, received in a socket of the body portion and held in position by a screw 32, whose inner end engages an annular groove formed about the reduced neck 33 of the post, Fig. 3. The upper endl of the post ends being disposed in -passes through the inclined opening of a hollow boss 34 of the lever, a pin 35 being `passed transversely through .the boss and post. This arrangement of course permits the lever to have imparted thereto a slight movement or oscillation in a vert-ical plane apart from Aits rotation in a horizontal planey about the axis'of the post 31,' so that as the lever is swung horizontally in one direction or the other from its normal central position, Fig.

l respectively depress the valve 20 and a valve 7. lVith such depression the syrup' (which is at all times free to flow into the receptacle 1) discharges through the passage 17 into the water-discharge passage 18, and the water likewise flows into the passage 18 through the passage 24, where the two mingle and jointly flow through the nozzle 14. Should it be desirable to draw only Water, the lever is given a slight vertical oscillation, (see dotted position, Fig. 3,) which suffices to depress the valve 20 off its seat and allow the carbonated Water to rush into the passage 18 andnozzle 14. The swing of the lever 30 is limited in either direction by a pin 36 on the body portion engaging the radiating pins 37 37 on the lever. The Word stems as used in the specification and claims herein ofcourse has reference to that portion or extension of a valve beyond the passage or opening which it controls.`

From the foregoing it will be seen that the present faucet operates substantially as oi'ir previous inventions; but the same has been materially sipinpliiied in particulars, Whose advantages must be apparent from the detailed description herein. It may be stated in passing that the heads 8 of the valve-stems being free to ass through the tops of the screw-caps 2 t e diaphra ms 4 are resorted to to prevent leakage of tie syrups through the top of the casting.

Having described our invention, what We claim is*- 1. A faucet comprising a body portion chambered for the passage of syrup and water from suitable sources of supply, a discharge nozzle, discharge passages /leading .from the chambered portions to said discharge-nozzle, feed-passages communicating with the chambered portions and with the discharge-nozzle respectively, valves controlling tlie liquid discharges, stems formed willi the valves and passing through the chambered portions, and yielding diapliragnis spanning the chambered portions receiving the syrup and coupled respectively to the chamber-walls and to the valve-stems, substanti ally as set forth.

2. A faucet comprising a body portion chambered, for the passage of syrup and Water from suitable sources of supply, a disch arge nozzle, dischargepassages leading from the chambered portions to said discharge-nozzle, feed-passages communicating with the chambered portions and with the discharge-nozzle respectively, valves con-l trolling the liquid discharges, stems formed with the valves and passing through the chambered portions, vyielding diaphragms coupled centrally to the valve-stems, seats or shoulders formed on the Walls of the syrup-chambers and means for clamping the edges of the diaphragnis to the seats, substantially as set forth.

. 3. In a faucet, a body portion chambered for the passage of syrup, a valve-stem operating therein, a yielding diaphragm secured centrally to the stein, a walls of the chamber, and a screw-cap enveloping the stem and adapted to force the edges of the diaphragm against the seat, substantially as set forth..

In testimony whereof we aflix our signatures in presence of two witnesses.
