IMPROVED DRAFT-COCK FOR SODA-WATERAPPARATUS.
Specification formingpart of Letters Patent No. 56.709, dated July 3l, 1866.
To all whom it may concern:
Be it known that I, WILLIAM P. CLARK, of Boston, in the county of Suffolk and .State of Massachusetts, have invented a new and useful Improvement in Cocks for Soda-Fountains; and I do hereby declare that the following is a full, clear, and exact description ofthe mode of constructing and operating the same, reference being had to the annexed drawings, in which- Figure 1 is a side elevation. Fig. 2 is a central vertical longitudinal section. Fig. 3-
is a Similar section, showing the valve partly raised; and Fig. @L a similar section, showing the valve as entirely open.
In the different views the same letters refer to identical parts.
'The purpose of my invention is to so arrange the valve of a stopcock to a soda-fountain that by a simple adjustment of thevalve there may be drawn sharp or fiat Soda, as desired. It will be understood that by the term sharp l? soda I mean soda-water that is drawn under a high pressure passing through a small orifice, and by dat soda I mean the same water drawn through wide openings, relieving it from the pressure.
A is the chamber or body of the cock, into which the soda-water passes through the induction -pipe B, and from which it passes through the mouth C, the flow being controlled by the handwheel D on the stem E, which is attached to the valve. The stem E has a screw-thread cut around it, by which its passage through the top of the chamber A is controlled.
There are two valves, F and G. The former is central and attached to the lower end of the stem E. The valve G is cupformed, Surrounding the stem E, and extending over and around the valve F, so as to rest upon a lower valve-seat. IVhen the valve G is on its seat there is a slight space between the upper part of the valve and the flangeE', on the lower end of the stem E, as will be seen by examining Fig. 2. A spiral spring, G', surrounding the stem E within the chamber, bears down upon the top of the valve G.
To the extent that the space is allowed between the top of the valve G and the ange E' it is obvious that the internal valve, F, may be raised without affecting the valve G, th rough the opening in the top of which the stem E may move up and down, the friction not being equal to the pressure of the spring G'.
The soda-water enters from the pipe B into the pipe H, which leads to and discharges under the center ofthe valve F, and in the middle of the chamber, in` the projection H'. The valve F rests upon this projection when closed. On each side of the projection H' is a small orifice, I, leading downward and into the vertical pipe I', discharging from the center of the cock. The orifices I are through the base K, surrounding the projection H', and within the valve G, which rests upon the outer edge of the base K,.which forms the seat of the valve G. Surrounding this valve-seat are a number of orilices, L, affording the freest possible ilow to the soda downward into the circular chamber L', from which it passes through the annular opening M and mouth C.
'Ihe operation of the cock-vis as follows: The soda-water is under pressure in a fountain or receiver, into which is inserted the pipe B. The ow of the soda through the cock is prevented by the valve F, resting upon its seat H'. By turning the Vhand-wheel D, say, onequarter of a revolution, the valve F is slightly raised, but the valve G is Ilot disturbed. The soda-water now rushes with great force through the opening H under the valve F, and downward through the oriiices I. This is the sharp soda. By turning the hand-wheel still more the valve G is. raised from its seat K, and the soda flowing freely on all sides through the openings L, the pressure is relieved andthe soda iiows flat.
These respective operations are shown in Figs. 3 and 4, the course of the water being indicated by the arrows.
Having. fully explained4 my improved sbdacock, what I claim as my invention, and seek to secure by Letters Patent, is-
A soda -cock constructed with an indue tion-pipe, H, and two sets of eductiox'rpipes, I and L, and two Valves, F and G, actuated successively by a common stem, E, and resting upon different valve-seats, said several parts being respectively constructed, and the whole combined and arranged for operation, substantially as set forth.
In testimony whereof I have signed myv name to this specification in the presence of two subscribing witnesses.
WM. P. CLARK.
