CHARLES H. DE WITT, OF WEATHERLY, PENNSYLVANIA.
GAGE-COCK.
SPECIFICATION forming part of Letters Patent N o. 326.022, dated September 8, 1885.
Application mea April 11, rees. (No model.)
To all whom t may concern Beit known that I, CHARLES H. DE WITT,-
a citizen of the United States, residing at Weatherly, in the county of Carbon, State of Pennsylvania, have invented a new and useful Improvement` in Gage-Cocks, which improvemcnt is fully set forth in the following specification and accompanying drawings, in Whichl Figures 1 and 2 represent longitudinal sections of a gageeock embodying myinvention, the valves being in different positions, and Fig. 3 an end view thereof.
The nature of my invention is a gage-cook in which the valve is prevented Vfrom wearing and tearing its seat and forcibly closing against the same.
Referring to the drawings, A represents the shell or body of a gage-cock having a valvechambenB; O, the valve; D, the valve-stem;
E, the inlet, and F the discharge-pipe, said` stem and' valve being loosely or freely connected.
The chamber B hasa valve-seat at each end,
and the valve C is double, or has two headsv located at opposite places so that itl may close against either seat.
Within the chamberB is a spring, Gyvvhichv bears against a shoulder on the valve C for forcing the valve in the direction toward the stem D when there is no pressure in the boiler. As previously stated, the stein and valve are loosely orfreely connected. This is accomplished in the present case by forming an opening in the inner end of the stem, and the adjacent end of the shank of the valve enters said opening; or, if desired, the opening may be in the shank of the valve, and the end of the stem enters the same; but in all cases there is a loose or free connection of the valve and its stem, so that the rotation of the stem does notimpart rotation to the valve, itbeing noticed that the steam keeps the valve properl y against the scat.
When the parts are in the position shown in thedrawings, Fig. 1, the cock is properly closed, the main head of the valve resting against its seat of the valve. In order to open the valve the stem is rotated, and the head of the valve just referred to leaves its' seat, the effect of which is evident, it being seen that the valve moves in advance of the stem Without, however, rotating. n
The valve may be closed by properly rota ting the stem, in which case it reaches its seat, due to the action of the steam. Should there be leakage of the valve at said seat, then the seat on the end of the chamber toward the inlet is brought into service, in which case the stem is rotated until the relative head of the valve is permitted to reach thelast-naincd seat, and the latter is then employed for Vthe purposes of the cock instead of the seat, Where the leakage occurs. l
While the valve operates with certainty in relation to either of its seats, its non-rotating nature prevents it from wearing or tearing the seat, and as the stem is threaded said stem causes the valve to move gradually and easily and the valve is held tight on its seat.
The inlet portion E of the cock which is Within the boiler is perforated around its periphery and at the end ,so that water is permitted to circulate constantly through said portion, thus preventing the openings in said portion from closing and the passage of dirt and scale through the cock.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`- 1. A gage-cock having its valve and valvestem freely connected by having a projection on one of the said parts fitting in a recess of the other, substantially as described.
2. A gage-cock having a double valve, a valve-stem freely connected with thel valve, and a spring, substantially as described.
3. A gage-cock having a double valve, a valve-chamber with two seats, a valve-stem freely connected with the valve, and a spring` bearing against the latter and pressing it toward the stem, substantially as described.
