PATENT FFIGE.l
JOSEPH TRENI", OF MILLERTON, NEW YORK.
IMPROVEMENT IN BALANCED STEAM-VALVES.
Specication forming part of Letters Patent No. 59,096, dated October 23, 1865; autedated October 7,1866.
To all whom it may concern:
Be it known that I, JOSEPH TRENT, of Millertou, county of Dutchess, and State of New York, have invented a new and useful nearly even balanced rlubular Slide -Valv'e for Steam and other Engines; and do hereby declare the same is fully described and represented in the following specification and the accompanying drawings, of Which- Figure l is a side elevation; Fig. 2, an end elevation; Fig. 3, a longitudinal section; and Fig. 4, a transverse section.
The nature of my invention consists in so constructing a steam slide-valve that the same shall be made not only to perform at the same time the functions of steam-chest and steam slide-valve in connection with a steam'engine, but in like manner be made the medium of communication between the steam-boiler and the cylinde-r of the steam-engine; and this I accomplish by passing the steam through the valve, thus producing a balanced, or nearly balanced, tubular slide-val ve, as will be hereinafter explained.
In the drawings, A represents a cylindrical stand for reception of the tubular slide-valve. The said stand has on its ends flanges B B, for reception of its heads G C, one of the said heads having connected thereto the steamsupply pipe O'. D is the base or valve-seat, with steam-entrance ports E E, and F the steam-exhaust port. rlhe said stand may be cast on or bolted to the cylinder through its foot or sole plate G. y
H is the tubular steam-valve, with cylindrical exterior, which slides freely within the concave interior of the stand A, and receives the steam through the supply-pipe G in its interior I, from which are steam-outlets K K, or ports of communication with the cylinder; and L is the valve-rod attached to one end of the valve H, for the purpose of directing its longitudinal movements, as shown in the drawings.
To further explain my invention, I will proi ceed as follows:
The steam being let on through the supplypipe O', the interior I of the valve H will be' immediately filled with steam, the tendency of which will be to press nearly with equal force against all parts of the interior of said valve, in consequence of which there will be but little resistance to the longitudinal or back and forward movements of the same.
Besides this, the valve H being fitted to and encircled by the stand A, the valve will not be raised from its seat, (giving the 'steam a chance to take a contrary direction, as Well as binding the valverod against the stuffing-box, incidental and common to the ordinary steamchest and valve,) nor will it (the valve) be pressed with unequal force against the eni trance-ports or valve-seat, requiring more of the power of the engine than requisite to operate it, but will, onthe contrary, be borne with nearly equal force against all points on the interior ofthe stand, in consequence of its being filled bythe steam, and thus will be nearly evenly balanced, tending thereby to give ease and buoyancy to the movements of the valve and valve-rod.
From the above it will be seen that I have produced a nearly even-balanced tubular slide valve of great utility in its application to steam or other engines.
I do not claim a tubular valve'whose moveA ments reciprocate conversely with its length, for such is not new; but
-What I do claim, and desire to secure by Letters Patent, is
The. above-described construction and arrangement of a tubular slide-valve for steam or other engines, substantially as and for the purposes set forth.
In testimony whereof I have hereunto set my signature.
JOSEPH TRENT.
