COCK FOR SODA-WATER. FOUNTAINS.

SPECIFICATION forming part of Letters Patent No. 333,651, dated January 5, 1886.

Application filed May 29, 1885. SerialNo. 166,991. (No model.)

To all whom it may concern:

Be it known that we, JOHN H. MATTHEWS, a resident of Brooklyn, in the county of Kings and State of New York, TnoMAs DYsoN, a 5 resident of New York city, in the county and State of New York, and J OHN ORMEROD, of Brooklyn, Kings county, State of New York, have jointly invented an Improved Cook for Soda-Water Fountains, of which the following I is a full, clear, and exact description, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a soda-water fountain having our improved cock." Fig. 2 I is an enlarged top view of the cock. Fig. 3 is alongitudinal section on theline c c, Fig. 4, of said cock. Fig. 4 is a cross-section of the same on the line 70k, Fig. 3.

This invention relates to certain improve- 2o ments on the soda-water-fountain cock which is represented and described in Letters Patent No. 260,037, dated June 27, 1882.

The principal object of this invention is to so construct the valve in its relation to the spring with which it is connected that said spring shall assist in holding the valve closed,

instead of being made use of for pushing said valve open, as stated in said former patent.

Ourinvention consis ts in locating the spring around the valve within a separate chamber,

' clamp; in so combining the valve with the spring that it will be closed by the pressure of the liquid or gas (if the vessel contains liquid or gas under pressure) and that of the spring; in a clamp to which the liquid-dis- 0 charge pipe is swiveled at one end, and to which the adjustingscrew for the valve is secured at the other end; in a clamp which holds two cushioned seats at one end, all arranged so that the'valve will be opened by causing it to move toward the screw that is turned for opening it, and in other details of improvement, that are hereinafter more fully specified. Inthe drawings, the letter Arepresents the shell of the cock, which is drilled longitudi- 5o nally for the reception of the valve B. This valve is hollow, having a tubular passage, a, that leads from its open end to a series of transverse holes, b, which traverse it near its closed end, the closed end of the valve being shown at d in the drawings. Over this closed end of the valve is screwed a cap, 6, which furnishes the seating-surface f of the valve, said seating-surface being packed with leather or otherwise cushioned to bear against the valve-seat g, which is formed within the shell A. as represented in Fig. 3. That endjof the valve B which we have termed the open end has an outwardlyextending rim or shoulder, h. Between this rim or shou and the inwardly-projecting portion g of the shell A is formed, around the valve B and within said shell, an annular chamber, z',within which is placed the spring G,that holds said valve shutthat is to say, the said spring, hearing with one end against a packing-ring,

j, which abuts against the projecting portion 9 of the shell, and with the other end against the shoulder It, tends to push the valve with its open end forward, therebygicrowding' its seat portion f against the seat g, and holding the apertures I) closed, all as represented in Fig. 3. into that end of the shell A which is nearest the closed end of the valve B is screwed a plug, D, which completes the chamber Z, with which the apertures b communicate whenever the valve is opened. I E is the clamp. It is a rectangular or substantially rectangular metallic frame carrying 8 5 a scre F, in one end, and a swiveled T- shaped block, G, in the other end, said block G being tubular in two of its arms, as at m in Fig. 3, while its third arm, n, constitutes a swivel for connecting it with the clamp E. The chamber Z communicates by a passage, 00, with the soda-water fountain or other vessel, while the bore m communicates with the dischargepipe. As far as we have described the mechanism 5 it operates as follows: When the cock shown is by its threaded end 0 screwed into a sodawater fountain, H, or other vessel, the spring block G at the end nearest the valve B forms- 0 alone, and if saidwessel contains aerated liquid or gaseous contents, the said spring in connection with the gas-pressure from within the vessel, will hold the valve B closed. The open end of the valve communicates with the passage m, that leads to the discharge-pipe, provided the clamp E is placed around the cock. When it is desired to open the valve, so as to discharge from the fountain or other vessel, the screw F is turned. This screw, bearing against the plug D, will, when turned in the threaded clamp, draw the clamp in the direction of the arrow, which is shownin Fig. 3, thereby crowding the hollow block G against the open end of the valve B, and pushing said valve also in the direction of said arrow until the holes 6 of the valve communicate with the chamber Z. The valve is now open and the fountain discharges; but on unscrewing F the spring, aided, if such be present, by the gaspressure from within the fountain, draws the valve closed and brings all the parts back into the position shown in Fig. 3. The hollow a cushioned seat, r, which bears against the valve B in pushing the same open. Back of the seat r is, on said hollow block G, another larger seat, 3, also cushioned, which, when the valve is open, bears against the end of the shell A, and serves the purpose of a stuffing-box or hydraulic washer that would otherwise be required around the valve-spindle. This second seat, 8, also serves as a check to prevent the valve being opened too far and the spring 0 from being unduly expanded. It will be perceived that the spring 0 is always out of con. tact with the liquid that passes through the cock, and is'therefore not liable to contaminate said liquid, nor to be affected by it.

As compared with the apparatus shown-in Letters Patent No. 260,037, this contrivance possesses sundry important advantages. In the first place it has fewer openings, and is therefore less likely to leak; secondly, it is composed of a less number of parts, making the instrument simpler, so that there is less liability of disarrangement or injury; thirdly,

' the fastening of the clamp to the cock andthe opening of the valve are both effected by a single screw, while in the former patent two screws were needed for this purpose. The clamp itself is simpler and less expensive in construction than that shown in said patent, the spring is not in the beverage passage, and the beverage itself comes in cont-act with nothing but the block-tinor White metal with which the shell A, plug D, and pipe G are lined, and of which the valve itself is or may be constructed. The pressure of the spring serves to close the valve, thereby'greatly diminishing the chance of leakage, while in the former patent it was needed to open the valve, and also counteracted by the pressure of gas in the fountain. The clamp is stronger than that shown in the former patent, and there are recesses formedone, p, in the plug 1) for the reception of the screw F, the other,

the clamp still remain fixed in its place on the cock. This is clearly represented in Fig. 3, where the valve is shown closed, although the clamp E, with its attachments, is still support-ed by the shell A. 1

In the lower part of Fig. 3 thereis also represented the additional valve,B which is of the same construction as the valve B, and which is embraced by a spring, 0 and moved open by a clamp, E and screw F, in the same manner as has been described with reference to the valve B, spring 3, clamp E, and screw F, this additional valve being intended to control the admission of gas to the fountain, and taking the place of the second valve shown for the same purpose in said former patent. The only difference between the clamps E and E is, that the gas-inlet pipe at is rigid on the clamp E while it is swiveled on the clamp E. Moreover, the clamp E, as appears from Fig. 2, is only three-sided, while the clamp E, by preference, is rectangular, as already stated; but the clamp E may also have only three sides, if desired, the same as IE We claim- 1. The combination of the tubular valve B, having apertures 6 near one end and enlarge.- ments f and h, with the shell A, having inwardly-projecting valve-seat g,whioh is adapted to close all the apertures 12, and with the spring O,which embraces the valve, and which is kept from contact with the liquid in the chamberi' of the shell between the enlarge+ ment h, fixed seat 9, unperforated part of the valve and outer shell, A, substantially as herein shown and described.

2. The hollow valve B, combined with the shell A, plug D, clamp E, and screw F, the clamp carrying the pipe m, all arranged so that when said parts are in operative connection the tube m is in contact with the open end of the valve, substantially as herein shown and described.

3. The hollow block G,having annular seats r and s, in combination with the valve B and shell A, against which said seats are caused to bear successively, as set forth.

4:. The combination of the shell A, which is closed at one end and open at the other end, and which has the inwardly-projecting valveseat 9 near its middle,and the separated chambers i and Z, with a hollow valve placed into the open end of said shell, and with the spring O,surrounding said hollow valve and kept from contact with the liquid in the chamber 2', said spring being adapted to hold the valve against its seat, substantially as herein shown and described.

5. The combination of the clamp E with the screw F and swiveled block G, having tube in, and with the shell A and valve B, substantially as specified.

6. The combination of the clamp E with the screw F in one end thereof, block G in the too the recessed parts of the shell and plug will x0 still hold the clamp in position on the shell, as specified. 1
