IMPROVEMENT IN 'VALVE-COCKS.
The Schedine referred to in these Letters P-atent and making part o! the same.
To all whom it may conce/m Be it known that I, O. R. VAILLANT, of Whistler, in the county of Mobile,rand State of Alabama, have invented a new and useful Improvement in Valve- Cocks; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art t make and use the same, reference being had to the accompanying draw- A, ings, forming part of this specification.
This invention relates to a new and usefulimprovement in cocks or faucets for discharging liquids or fluids, more especially designed for try-cocks or petcocks for steam-boilers, force-pumps, and similar purposes, and consists in arranging and operating, in a suitably-constructed shell, two valves, by means of a lever, as hereinafter more fully described. A
The accompanying drawing represents a vertical section of a valve-cock, constructed according to my invention. l
Similar letters of reference indicate corresponding parts.
A is the shell, with a base and cap. Bis the valve-stem, in two parts. C is the lowerorpuppet-valve, which closes on to the seat D.. E is the upper aud,pistonvalve, which is. packed tightly in its chamber.
Gis the base of the shell, which is connected, di-
rectly, with a force-pumpror pipe.
H is the cap of the shell, through which the valverod B works..
I is the discharge-tube, which communicates with the main chamber J.
In this chamber J, there is a spiral spring, K, which bears upon the bottom of the chamber, at its lower end, and against the valve E at its upper end, with a const-ant pressure.
The lower valve 1s provided with'wings, (three or more,) which guide it to itsrseat, Vand it forms a part of or is rigidly attached to the 'stem B.
gineer to The upper valve screws on to the lower portion of l the stem-valve B, as seen at L, and is packed, so as to work water-tight in its chamber fm.
This valve works like a piston, in a cylinder, the packingV of which prevents the upward discharge of water, whether the valve closes down on to the seat F or not. f
The upper portion of the valve E formsA the upper portion of the stem B, to the top end of which the power is applied for actuating the cock.
N is the lever, which hasits fulrum yon the arm O,
at P.
The end ofthe lever simply bears upon the/end of the -valve-stem, as seen in the drawing, so that by raising the longend of the lever, the stem (with the valves) vwill be depressed. This action opens the `valve O, and allows water or steam to be discharged.
. When the action of the lever on the stem ceases, the pressure of the steam or water on the valve() will close the valve, the spring K being simply to hold the valve in place,-when Athere is lno pressure of steam or Witnesses:
