PATENT OFFICE.
STEAM-COCK.
SPECIFICATION forming part of Letters Patent No. 239,645, dated April 5, 1881;
Application filed July 21, 1880. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM BEoNIQof Albany, in the `county of Albany and State of New York, have invented a new and useful Improvement in Steam-Cocks, of which the following is a specification. l
The object of this invention is to provide a steam-cock with a safe and self-adj ustable check-valve for steam and other purposes.
Figure 1 is a vertical sectional elevation of the device in place on a boiler, showing the check-valve closed.` Fig. 2 is a vertical ele# vation, partly in sect-ion, ot' a p'ortin ot' the device, showing the cbeck-valve opened. Fig. 3 is a transverse section onlinex Fig. 2.
Similar letters ot reference indicate corresponding parts.
In the drawings, A represents a steamcock ofordinary construction, provided with a valve- 2o stem, B, valve (l, and valve-seat C.
Projecting from the under face of the valve C is a pin, D, passing downward through the valve-seatC/.and in contact with the self-adjusting valve E, which valve E projects beyond the end of the steam-cock A and has its seat in the end thereof, as shown at a. The stem of this valve E is slotted longitudinally, as shown at b, into which slot the pin or screur c projects through the side of the cockV A, 3o whereby the said valve E is held in place with freedom to move up and down to open and to close the end ot said cock A.
F represents the boiler, to which the cock A is applied, the end of the said cock projecting 3 5 through the shell of the boiler, as shown in Fig. l.
When the valve C is retracted, as shown in Fig. 1, the steam in the boiler closes the valve E in its seat a, as shown, so that no steam can 4o escape into or through the cock A. When the valve C is but partially closed down to its seat G', the steam from the boilerv will escape through the channels f in the sides of the valve E and out through the exitrot' the cock A, the pin D moving the valve E from its seat a.
The valve G operates the same as in a valve of any ordinary steam-cock, without reference Y to the valve E, in shutting oft or permitting 5o the escape of steam, the valve E being an auxiliary valve of especial advantage in case of accident or when any part of the cock outside of the boiler requires repairs. Should the cock A become broken short ottflush with the outer face ot' the boiler-sheet F, as is not un- 55 frequently the case with steamcocks Where collisions and other accidents occur on railroads, the pressure of steam within the boiler will close the valve E into its seat a, and thereby prevent the escape ot steam to injure 6o those within the cab of the locomotive; or, should it be necessary to remove the valve or. any other part of the cock A that is outside of` the boiler for the purpose of repairs, the valve E will remain closed by the pressure ot' steam 65 within the boiler, thus obviating the usual necessity ot' cooling down the boiler before removing the steam-cock or its ordinary valve for the purpose ot repairing it. Thus it will be seen that in case of accident to a locomotive 7o this valve E may operate as a safety-valve, and when repairs upon the cock are required it will operate to save time and the cost of cooling down the tires and retiring.
As the valve E automatically closes the cock A against pressure from within a boiler or the vessel to which said cock may be applied, itis evident that said cock A may be applied to beer-barrels, gasreservoirs, andi the like with great advantage.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the cock A, having its rear end threaded to screw into the boiler, and provided with the valve-seat a, of the valve E, slotted-atff, and having a groove,
b, workin g on a screw,c, whereby the said valve may be closed by the boiler-steam and opened by a push-pin, for the purpose specified. 9o
2. The combination, with valves C E of a l steam-cock, ofthe pin D', substantially as herein shown and described, whereby the valve E is opened as the valve G is closed, as set forth.
