FAUCET FOR SODA-FOUNTAINS.

SPECIFICATIONforming part of Letters Patent N 0. 766,420, dated August 2,1904. Application filed July 27, 1903. Serial No. 167,115. (No model.)

To (0 whom, it 'HLILZ/ concern:

Be it known that I, ELIAS J. CALLEY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Faucets for Soda-Fountains; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present invention is designed to provide a faucet simpler of construction, easier of operation, and more durable than the fancet commonly utilized in connection with soda-fountains for the drawing of soda-water, the invention residing more particularly in the construction of the valve means for controlling the flow of the water from the faucettube into the outlet-ports of the faucets.

In order to comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein Figure l is a vertical sectional view of the faucet, the handle being positioned to close the outlet-ports against the escape of liquor from the receiving-chamber. Fig. 2 is an end view of the faucet, the faucet-tube and a portion of the faucet-body being removed. Fig. 3 is a top plan view of the faucet with its cap and retaining-ring removed, the diaphragm-valve and its protecting-plate being partly broken away. Fig. 4: is an enlarged detail broken sectional view of the faucets body, the position of the diaphragm-valve being illustrated when raised to open one of the outlet-ports for the escape of liquor from the receiving-chamber of the faucet. Fig. 5 is a detail plan view disclosing a modification of the retaining-ring and the valve, the valve being illustrated as united to the said ring; and Fig. 6 is a cross-sectional view in elevation of the ring and valve set forth in Fig. 5 of the drawings.

The numeral 1 is used to designate the supply-tube for the faucet, which tube leads from apressure-reservoir, (not shown,) and its free end communicates with the inlet-port 2 in the body 3 of the faucet. This port coinmunicates with a chamber a, formed between the head etof the body 3 and the under face of the flexible diaphragm-valve 5, so that said chamber is'at all times filled with liquid under pressure.

\Vithin the body 3 of the faucet the usual outlet passage- ways 6, 7, and 8 are formed, two of said passage-ways (5 7 leading from the outlet-port 8. Said passage-ways 6 7diverge a slight distance below the port 8 and terminate near the outer edge of the boss 9, so that the liquid flowing thercthrough will strike against the bell l0 and be deflected toa, being held in place within the circular flange 5 of the body 3 by means of the retaining ring 15. Said ring is exteriorly screw-thrczuled and screws into the circular interiorly-screw-threaded flange 5. By means of this retaining-ring the valve is lirmly held in place, the same covering the outlet-ports 8 9. It is necessary that the valve be held to close the ports 8 9, else the pressure within the chamber .t will raise the free portion of the said diaphragm-valve to open the ports and permit the escape of the liquid. The valve is held against the ports 8 9' to close the same by means of the hereinafter-described valve-rods 16 16.

\Vhen the diaphragmvalve 5 is made of leather and separate from the ring 15, which holds the same down onto the shoulder 14, it is required that ainetallic plate 16 be used to cover that portion of the valve not engaged by the heads of the stems or valve-rods 16 16. The purpose of this is to hold the uncovered portion of the valve against being forced upward by the pressure within the chamber at, the tendency of which would be to unduly strain the leather and cause leakage by bursting of the valve. However, the valve 5 may be made of thin metal, such as copper, and united to the retaining-ring, as disclosed by Figs. 5 and 6 of the drawings, in which case the plate 16 may be dispensed with, inasmuch as in such case the strength of the metallic valve is sufiicient to resist the pressure within the chamber 4. I It will be understood that the disk or plate 16 when used is held down onto the valve by the retaining-ring 15.

The valve rods or stems 16 16 work through the cap 17, which cap is attached to the body 3 by means of the coupling 17. This coupling screws onto the flange 5, the circular flange 18 of the coupling engaging with the outwardly-projecting circular shoulder 18 of the cap 17.

The heads 19 19 of the valve rods or stems 16 16 Work through openings 20 in the plate 16 where the plate is employed and bear upon such portions of the valve 5 as cover the outletports 8 9, the heads being held down to press such portions of the valve firmly onto the said ports 8 9 to hold same closed by the tension of the springs 20, which springs surround the lower portion of the valve rods or stems 16 16, being interposed between the under face of the cap 17 and the heads 19 19.

The valve rods or stems 16 16 work through the stufiing-glands a of the cap 17, said rods or stems being connected by links 21 22 to the vertically-movable handle 23, which handle is fulcrumed to the standard or support 23 upwardly projecting from the'cap 17.

In the drawing of soda-water from the fountain the outer end of the handle 23 is raised to lift the head 19, through the valve-rod or stem connection 16, clear of the diaphragm- 'valve 5 and depress the head 19 down onto the said valve to tightly seat same to close the port 9. The valve area covering the port 8 being thus released, the pressure of the liquid within the chamber 4: lifts or raises such portion of the valve clear of the port 8 and permits the liquor to flow therethrough into the passage-ways 6 and 7. The liquor thus escap ing from the receiving-chamber 1 through the passage-ways 6 7 unites within the tip 11, flowing therefrom as a solid stream, commonly termed the coarse or heavy stream. In

order to stir up the contents of the glass and.

give a foam to the liquor discharged therein, itis required that a fine jet or streambe ejected from the faucet. This is accomplished by depressing the handle above its normal or horizontal position, which movement depresses the head 19 onto the valve to close the outletport 8 against the escape of liquor and raises the head 19 clear of the valve 5. The valve area immediately above the outlet-port 9' being thus released, the same is raised or unseated by the pressure within the chamber 4: and the outlet-port 9 uncovered. When thus uncovered or opened, the liquor will flow from the chamber l: into the passage-way 8 through said outlet-port, being discharged from the nozzle 12. This constitutes the fine stream of the faucet.

' To close the faucet, it is only necessary to release the handle 23, when the pressure of the springs 20 will cause the heads 19 19 to bear upon the valve area covered thereby with sufficient pressure to seat the valve to firmly close the ports 8 and 9 against leakage;

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is

In a faucet of the described character, the combination with the body thereof, a receiving-chamber therein, outlet-ports communicating therewith, a flexible diaphragm-valve covering the said ports, a retaining-ring for holding the valve in position, spring-pressed valve-rods for holding portions of the valve pressed onto the outlet-ports to close the same, a fulcrumed handle for actuating said springpressed valve-rods, connection between the valve-rods and the handle so that as the handle is depressed and raised one of said rods is moved away from the valve in order that such area of the same maybe free to rise with the pressure within the receiving-chamber to open the port covered thereby.

In witness whereof I have hereunto set my hand.

ELIAS J. GALLEY.
