UNITED. STATES PATENT OFFICE.
CHARLOTTE THOMAS, OF SACRAMENTO, CALIFORNIA, EXECUTRIX OF WILLIAM H. THOMAS, DECEASED.
y IMPROVEMENT m PUMP-VALVES.
Specification forming part of Letters Patent No. 181,497, dated August 22, 1876; application filed April 10, 1876.
To all whom it may concern Be it known that W. H. THOMAS, deceased, late of the cityand county of Sacramento, State of- California, did invent a certain Improved Fump-Valve; and the following specification is a full and exact description of the same, reference being, had to the accompanying drawing, in which Figure 1 is a vertical section. Fig. 2 is a cross-section on line a: w of Fig. 1, and Fig. 3 a bottom-plan view of the valve and its case.
The object of the invention is to provide an improved substitute for puppet-valves heretofore in use.
To this end the invention relates particularly to the valve-seat,composed' of hard metal and having a beveled rim, the metal valve having an annulus of soft metal secured in a suitable cavity, and the vertical guides for causing the valve to seat itself accurately, these elements being conjoined under the particular arrangement hereinafter described.
Referring to the drawing, B is the cylindrical valve-case; A, the valve, provided with.
tailed in cross-section, so that the'metal cannot be removed or displaced by the jarring occasioned by the operation of the valve. The raised valve-seat g is circular in form and beveled to a sharp edge, as shown, so that it will embed itself in the soft-metal annulus b. The stem Hot the valve guides it with considerable accuracy; but to insure a perfectly watertight joint it is necessary to employ the guidebars 0, in order to prevent the valve turning on its axis, and compel it to seat itself in such a manner that each part of the beveled rim will'always strike in the same part of the annulus. If the valve were allowed to turn on its axis a water-tight joint would be seldom formed, since the beveled rim will usually wear unequally, and the soft-metal annulus isordinarily not perfectly homogeneous in quality.
A valve provided with a soft-metal rim is not claimed; but
I claim- The combination of theraised beveled rim or seat 9, the notched valve, provided with the soft-metal annulus b, secured in a dovetail cavity, the vertical parallel guide-bars o a, projectingfrom the head L,as shown and described, to operate as specified.
