. No. 543,274. Patented July 23, 1895.




SPECIFICATION forming part of Letters Patent No. 543,274, dated July 23, 1895.

Application filed Tune 18, 1894. Renewed May 27, 1895. Serial No. 550,871. (No model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE F. SPEER, a citizen of the United States, residing at Tyler, in the county of Smith and State of Texas, have invented certain new -and usefulIm- .provements 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 inventionhas relation to valves; and it consists of a new valve and new valve-seat constructed substantially as shown in the4 accompanying drawings, in which Figure l is a side elevation of the valve,

partly in section, showin g my valve and valveseat in section. Fig. 2 is an edge view of the valve, partly in section, showing my valve and valve-seat in section, also the lever and lever-rest. Fig. 3 is an edge view of the lever.

My invention is described as follows: A represents the shell of the valve; B, the

' guide and cap; C, the stuffing-box nut; d, the

valve proper; e, the stuffing. f is the neck of the Vvalve running up through the guide and cap B, stuffing-box nut C, and against the lower face of the stern-nut g, which nut holds the valve down solidly against the upper face of the shoulder h of said valve-stem. Said valve-stem i extends entirely through the valve body and has on its lower end nuts jj to regulate the pitch of the valve-lever k.

In the shell A is my tempered-steel or other hardmetal gable-shaped valve-seat Z, and in the lower face of the valveis my removable soft contact-ring m, which may be made of brass or other material, in which the edge of my tempered-steel or other hard-metal gable-shaped seat may cut a water-tight lit.

The features of my invention which I claim as new and novel are: My tempered-steel or `other hard-metal gable-shaped seat Z, that can be removed and replaced when it begins to valve to seat and prevent it from cooking, the valve-joint being made by the brass ring fm, being pushed hard down on the temperedsteel seat, causing an impression of-seat to be cut in the brass ring of valve, the face of the seat being on line of bottom of'inlet to valve, which forms virtually a straightway valve.

By the seat being of tempered steel or other hardened material,`joint is not made by two perfect faces in contact, but by hardened seat cutting in the softer ring i'n valve.

Having described my invention, what I claim as new, and desire to secure byv Letters Patent, isi 1. The combination of the shell A, provided 'with the usual water-inlet andowater outlet, vand perforation for the valve stem to work -passing up through guide and capB; soft contact ring m, fitted in the face of the valve "d, and adapted to come in contactwith the edge of the gable-shaped seat Z; guide and cap B, fitting on the upper part of said shell; Vstuiiin,; ,'-b0x nut C, fitting on the upper end of said guide and cap; and stem nut g, working against the upper end of the neckf, and holding the valve d, rmly and securely against the upper face of the shoulder h, substantially as shown and described and for the purposes set forth.

2. In a valve, substantially as shown and described,'the valve CZ, provided withz a hollow neck f, adapted to work up and down through the guideB, and stuffing-box nut C; rod c', 'running through said valve d, and holding said valve firmly between its shoulder h, and nut g, vsubstantially as shown and described and'for the purposesy set forth.

In testimony whereof I affix my signature in presence of two witnesses;




any inside wearing parts of shell to guide A ssv
