GAGE-COCK.
SPECIFICATION forming part of Letters Patent No.3l0 .90, dated January 6, 1885.
Application filed February 16, 1884. (No model.)
To aZZ whom it may concern:
Be it known that we, JAMES A'rwoon and ALBERT W. SLATE, citizens of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Gage-Cocks, of which the following is a speci lication.
This invention relates to improvements in gage-cocks and other valves intended to be directly connected to a steam-boiler by having a part thereof pass through the shell of thelatter, the object being to provide gage-cocks and valves adapted for such connection with boilers in which the valve-closing parts are within the boiler and open against the steam-pressure, and which are adapted to prevent the dangerous escape of steam into the cab of a locomotive when, owing to accident, the projecting part of the gage'cock and valvespindle are broken off.
In the drawings forming part of this speeiii cation, Figure 1 is aside elevation, and Fig. 2 asimilar view, partly in section of a gage-cock embodying our invention. Fig. 3is a section of the valvespindle.
I11 the drawings, A is the valve-body, having its rear end screw-threaded in the usual manner, to adapt it to be screwed into the boilershell B, and is provided with the usual discharge-nozzle, The valve-body is provided with a longitudinally-central valvestem pas sage, and has a bevel-edged valve-seat formed in its rear end aroundthe end of said passage. The forward end of the body A is screwed to provide for the reception thereon oi the set nut c and the stufling-box nut 1).
Between the part of the body A nearest the outside of the boiler and that part thereof which is screwed into the latter is formed an annular groove, r, around the body, out sufiiciently deep to cause the metal between the base of the groove and the spindlepassage through the body to be of less thickness than any other part of the body, so that when the cook or valve is struck or forced laterally it will break off, if at all, at the point where the body is made thin and weak, as at the groove 1;. The spindle (Z is provided with a conical-shaped valve, (1, on its rear end,which seats against the end of the body A within the boiler, and that part of the spindle between the valve d and the nozzle 00 of the body is grooved longitudinally, so that steam and water may have a free passage from within the boiler along the spindle to the nozzle. A groove, 2, is made around the spindle d, to facilitate the discharge of water through the nozzle as the groove is brought wholly or partly opposite the latter when the valve is opened. The spindle d is made with an annular groove, 10, around it opposite the groove 1) in the body, so as to weaken it at that point, and should the body be broken off, as above described, to also cause the spindle to break off at the same time. Thus it will be seen that if the body A and spindle (Z be broken off while steam-pressure is on the boiler, the screwed part of the body in which is the valve-seat and the part of the spindle on which is the valved remain in the boiler, and, as the steanrpressure holds the valve d close against its seat, no steam can escape to burn and scald any one who may be near. The spindle d is provided with athread, which op crates in the tapped end of the stufiing-box b, and the latter incloses the usual packin 0, which is compressed around the spindle and prevents leaking. The striding-box can, while the steam is on the boiler, be turned off from the end of the body A, for the purpose of repaeking the spindle, without permitting any steam to escape, and when the box is replaced; as in Fig. 1, the set-nut c is screwed against the end of it, to prevent it from being jarred off. A wheel, 0, is placed on the endof the spindle to turn the latter by.
It is obvious that substantially the construction herein shown and described may be adopted for any valve to be used for dis charging steam from a boiler into a pipe, and for similar purposes, by adapting the end of the nozzlex to have a leading-pipe screwed ing from the Volvo-seat to the escape-port, 10
onto it. and a eireun'iferential groove, w, which is in .Vhat We claim as our invention isline with groove win the body when the valve The body A of a gage-cook, having a lonis on its sent, substantially as described. gitudinal passage providedwithunozzle, cap, JAMES B.
