VALVE CONSTRUCTION.

To all whom it may concern Be it known that I, ERNEST G. WAGNER, a citizen of the United States, residing at 'Lewiston, in the county of Nez Force and the valve may be readily opened, the means for opening the valve being independent thereof, whereby it is impossible for an in.- experienced person to jam the valve against its seat, and means also being provided for independently actuating the valve to pulverize or eject any accumulations of foreign or extraneous matter between the valve and its seat.

The present invention also contemplates the provision of a valve construction of the nature indicated, which will be comparatively simple, substantial, durable, compact and inexpensive, as well as simple, convenient and efiicient in its use.

lVith the foregoing general objects outlined, and with other objects in view, which will be apparent as the nature of the invention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein the figure is a longitudinal central section of the valve construction.

In carrying out the invention, there is provided a cylindrical body or casing 1,

preferably in the form of a casting and.

which has one end open. The body or casing 1 is provided with a lateral inlet port 2 adjoining its open end, and with an opposite lateral discharge port 3 adjoining the other end, the body or casing being provided with an inner annular rib or collar 4 intermediate the inlet and outlet ports and form;-

ing a contracted opening smaller in diameter than the open end of the casing.

Driven into or secured within the annular rib or collar 4:, is a valve seat 5 of suitable material, the same being preferably provided with a conical or beveled face at that side adjoining the inlet 2.

A cap 6 is threaded or otherwise engaged over the open end of the body or casing 1 and a relatively long guide sleeve 7 has one end threaded outwardly through a central tap provided in the cap 6, the guide sleeve 7 projecting axially into the body or casing 1 to a point near the valve seat, and having a counter bore or socket S in its outer end,

forming a stuffing box in which suitable v. packing 9 is disposed. A gland 10 is threaded into the stuffing box 8 to compress the packing.

A smooth stem or spindle 11 is freely sliclable and rotatable through the gland l0 and the guide sleeve 7 and is equipped with a valve 12 at its inner end, between the valve seat and cap and cooperating with the valve seat 5, the face of the valve being preferably conical or beveled about its margin, to seat against the face ofthe valve seat in an The valve stem 11 is slidable through the guide sleeve 7, to permit the valve to be seated by the pressure of the fluid entering the inlet port 2, the valve being of the check valve type.

The outer end of the valve stem 11 is squared or otherwise formed, as at 13, for the engagement of a suitable handle or lever 14, in order that the valve may be rotated and forced inwardly, to pulverize or eject any accumulation between the valve and its seat.

As a means for opening or unseating the valve, a relatively long plug 15 is threaded inwardly through the closed end of the body orvcasing l and projects to a point near the valve seat, and a spindle or screw 16 is threaded through the plug 15 so that its tip or inner end is adapted to be projected respects.

the packing being'compressible against the spindle or screw 16 by means of the cap 19.

The present valve construction may be employed in divers capacities,such as, for attaching a sprinkling hose to .a fire .hydrant for a blow-off for steam boilers, and the like. It will be evident that when the inlet port 2 is connected withv any fluid supply, the pressure of the fluid will normally seat the valve 12, that is, when the screw 16 is retracted. To open the valve, it is merely necessary to run the screw 16 inwardly, which will force the valve from its seat against the pressure of the fluid, in order that the fluid may flow through theannular valveseat and out the. discharge port 3. The valve being of the checkrvalve type, will close automatically when'the screw 16 is retracted, it being noted that the valve cannot be jammed against the valve seat through the medium of the screw 16, which will render it impossible to injure the valve or its seat by inexperienced persons. This is of importance, inasmuch as the amming of a valve against its. seat often results in the destruction or mutilation of the valve or its seat, which is of disadvantage in other A lthough the valve cannot be forced a ainst its seat, through the medium of the screw 16,'the valve may be forced inwardly and rotated properly through the medium of the valve stem 11 and its handle 14, in order that any sediment or accumulation between the valve and its seat, can be pulverized or ejected. The valve stem 11 being smooth and unthreaded, will prevent the valve, however, from being jammed with excessive force against the valve seat, the valve being released, as soon as the pressure is relieved from the valve stem.

Copies ef this patent may be obtained for From the foregoing, taken in connection with the drawing, the other advantages and capabilities of the present device will be apparent to those versed in theart, and-need 'not'be itemized at length, it being observed than said open end of the casing, a capenga'ged over the open end of the casing, a valve seat fitted withinsaid rib, a relatively long plug threaded through the other end of the casing, a relatively long guide sleeve threaded through the cap, a valve disposed between the valve seat and cap and seatable against the valve seat, the valve having a smooth stem slidable and rotatable freely through the guide sleeve, a valve unseating screw threaded through the said plug and adapted to'be projected through the said valve seat and abut against the valve, and packing means carried by the outer ends of the said plug and sleeve and embracing the screw and valve stem, respectively,- said plug and sleeve projecting to points near the valve seat.

In testimony that I claim the foregoing as my own, I have hereto aflixed my sig nature in the presence of two witnesses.
