I Application lilod Novrmhcrfll, i883.; (No model.) i l To all whom it may concern.'
Be it knownthat I, LOUIS B. FULTON, of
I Pittsburg, inthe county of Allegheny and State of Iennsy1vania,have invented certain new and useful Improvements in Gage-Cocks; and I do hereby declare that the following is a full, clear, and exact description of the invention,
which will enable others skilled in the art tol which it appertains to make and use the same,
reference being had to the accompaning drawings, which form a part of this specification, in which- Figure 1 is a central sectional view of a gage-cock provided with my improvement. Figs. 2 and 3 are transverse sectional views of the box p in Fig. l. Fig. 4 is an end viewof the box. Figs. 5 and 6 are respectively aside view and a central section of modilications.
This invention relates to gage-cocks; and it consists in the construction and combination of parts, substantially as hereinafter fully described and claimed.
My improvement is -applicable to gagecocks, whether closing with or against the pressure and rotating or not. Fig. l illustrates its application to a cock designed to close against the pressure.
A is the body of the cock, having thread b, for attachment to the boiler, and globe or'bulb c. Body A is formed with the nozzle d projecting forward into the globe c, formed cylindrical outside, and at its ends shaped into an outwardly-sloping valve-seat, e, as shown; or the seat c may slope inwardly, like auordinary valve-seat. A stuffing-box cap, f, screws onto the threaded outer end of body A, and admits through its central bore the stem g, having handle h and threaded enlargement fi, w hich screws into the internally-threaded neck k of body A. Enlargement il has at its rear end a central recess, m, with a hard-metal seat, u, in its bottom. In recess m fits the pin o, which carries thecage-valve, consisting of a box, p, whose internal diameter is slightly larger than the external diameter of the cylindrical nozzle d, and at its rear end has the inwardly-turned flange q, substantially fitting said nozzle d. At the front end of the chainber of box-p, I form the valve s. The length of cylindrical portion of nozzle d is such with reference to the movement of the'valve in opening and closing that the flange q does not Vmove off thenozzle d, which therefore constitutes a` guide for the valve and preserves its axial position. The same is true of the pin o with reference to the -recessm In the outer walls of box 12,1 form openings orl ports t,l for the escape of steam and Water when the valve is open. If the'valve is to rotate when opened, I form the openings or ports t at an angle, as in Fig. 2, so that the escaping steam or water will. strike the inclined walls of the ports and drive the valve in a rotary direction, otherwise I make the ports tsimply radial, as in Fig. 3. Y
Instead of the angular ports t, cut or formed in the walls of box p, I may form inclined slits t in the lip or. flange q, as in Fig. 4, for. rotating the valve. In any of these the valve remains the sarge as-before. In case of the closed globe c, the vent v is attached for escape of steam or water; but instead of the closed globe I propose an open cage or skeleton having the thread-fitting b and neck k, threaded as before, joined together by two or more arched bars, w. In this case the stufiing-box may be dispensed with, as the steam escapes directly from valve and box p. itself exposed to inspection while testing for water-level, so that its. operation may be observed. Such construction is fully illustrated by Fig. 5.
Obviously the invention is applicable to a cook shutting with the pressure. Such form is shown by Fig.. 6, where the valve-seat e and valve p s have` their relative positions reversed, and the stem o projects outwardly through the outer portion of the body, as in an ordinary Mississippi @tagte-Cock.7
I claim as my invention- 1. A gage-cock having an annular projecting valve-seat and a box surrounding the saine, and constituting the valve, and -provided with means of rot-ation under the force of escaping steam or water, substantially as described. v
2. A gage-cock having an annular projecting 'valve-seat with cylindrical body externally, and a box having an internal iiange or two or more projections fitting said cylindrical body,.and said box constituting the valve,
substantially as described, whereby the valve is guided and centered.
3.
