VALVE.

SPECIFICATION forming part of Letters Patent No. 635,214, dated October 17, 1899.

Application filed April 12, 1899.

To all, whont it may cancer-rt.-

Be it known that I, HENRY H. WHEELER, a citizen of the United States, residing at East St. Louis, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in valves; and it consists in the novel combination and arrangement of parts, as will be hereinafter more particularly described, and pointed out in the claim.

In the drawings, Figure 1 is a combined section and side elevation of my complete invention, and Fig. 2 is a vertical transverse section taken on the line x 00 of Fig. 1..

The object of my invention is to construct a valve to be used more particularly in connection with water-mains wherein a hose or other pipe is to be attached for directing the water to any given place, and is designed to keep up the circulation of water below the piston of the same when the latter is in a closed position, thereby preventing the water from freezing, the small amount of Water escapin g being conducted to any suitable reservoir or other place. When the piston or valve is in an open position for supplying water, the pressure of the latter is greatly relieved or reduced, and consequently very little of the same is lost.

Briefly stated, the invention consists of a valve-casing of any suitable design, having an inlet and outlet for the passage of the water, a piston which is adapted to be moved to and from a suitable valve-seat for regulating the supply of water through the valve, an annular chamber formed in the casing at a suitable distance from the valve-seat, ports formed in the inner wall of the casing and in communication with said annular chamber, screwthreaded openings formed in the outer wall surrounding the chamber,and screw-th readed plugs adapted to be screwed into said screwthreaded openings for closing any number of the screw-threaded openings, all of which will appear in the detail description now to follow.

Referring to the drawings, 1 represents a valve-casing of any suitable design and pro- Serial No. 712,767. (No model.)

vided with a screw-threaded extension 2, by means of which the said casing may be secured to the water-main in the well-known manner. As shown in the drawings, a screwthreaded cap 3 covers the opposite open end of the valve-casing 1 and is provided with an extension 4 and the usual stufling-box, (not shown,) through which a screw-threaded piston-rod 5 passes, the inner end of which loosely carries a piston 6 or other valve,which cooperates with the annular seat '7, all of Which is constructed in the well-known manner, the said casing being provided with an outlet 8, which is arranged at an incline, through which the water passes when the piston or valve is in an open position .or moved out of contact with the annular seat 7, said outlet being provided with the usual exterior screw-threads 9, by means of which a hose or other pipe is attached for supplying water to any desired place.

Formed in the valve-casing, adjacent to the threads 2 of the same, is an annular chamber 10, which is formed by the inner smooth circular wall 11 and the outer wall 12, the said annular chamber being in communication with the interior of the valve by small circumferentially-arranged ports 13, formed in said wall 11, through which the wateris adapted to pass and into the said annular chamber. Formed in the outer wall12 of the valvecasing are any number of screw-threaded openings 14, which are adapted to receive screw-threaded plugs 15, one of said plugs being usually removed, leaving the screwthreaded opening for the purpose of attaching a pipe, which leads to any suitable reservoir or other place, whereby when the piston or valve 6 is in a closed position a small amount of water is permitted to pass through the ports 13 into the annular chamber 10 and out through one of the larger screw-threaded openings 14, to which a pipe is attached, and thus a small amount of water is permitted to circulate and prevent the water from freezing within the valve-casing and water-main, to which the same is attached.

The object of having a number of screwthreaded openings 1 1 and plugs to close all but one of said openings is for the purpose of being able to place the valve in any position, should occasion require it,whereby the proper plug may be removed to more effectually drain the annular passage or chamber 10.

I do not limit myself to the application of my invention to the particular construction of valve herein shown and described, as-it is evident that the same may be applicable to any design or construction of valve Without departing from the nature of my invention.

Having fully described my invention, what I claim is A valve comprising a suitable casing, an annular valve-seat formed in the same, a valve or piston cooperating with said seat, an annular chamber surrounding the casing, and located adjacent to the valve-seat, said chamber forming inner and outer Walls, thesaid inner smooth wall being provided with small circumferentiallyarranged ports, whereby HENRY H. WHEELER. Witnesses:
