PIRE HYDRANT.
Patented June 1'7 UNITED STATES PATENT OFFICE.
WILLIAM T. Y. SCHENCK, OF SAN FRANCISCO, CALIFORNIA.
lFIRE-HYDRANT.
SPECIFICATION formingpart of Letters Patent No. 430,301, dated June 1'7, 1890.
Application filed November 15, 1889. Serial No.3301465. (No model.)
To a/ZZ whom it may concern,.-
Beit known that I, WILLIAM T. Y. SCHENCK, a citizen of the United States, residing at the city and county of San Francisco, State of California, have invented an Improvement in Fire-Hydrants; and I declare the following to be a full, clear, and exactdescription thereof.
My invention relates to that class of hydrants intended for cities, towns, and villages for attaching fire-hose; and it consists in the novel construction of valve movement and minor details hereinafter fully described, and. specically pointed out in the claims.
Referring to the accompanying drawings, Figure is a vertical section of my hydrant. Fig. 2 is a plan view to show the two-part ring H. Fig. 3 is a horizontal section of the valvecarrier C. Fig. 4. is a perspective view of the same. y
A is the hydrant shell or pipe, having the exit-opening a.
B is the hydrant-cap. From the under side of this cap depends an arm b, which lies to one side of the centerof the cap. To the lower end of this arm is pivoted at b the elbow or bell-crank lever, which forms the valve-carrier C. To one arm of this is connected the valve D, and in the other arm is carried the nut E. This carrier is formed of two separate plates secured together. The ends which carry the valve are thickened, and in these is made a spherical socket c, in which the spherical-ended stein d of the valve is mounted, so that said valve is connected freely and is adapted to find its seat accurately. This lconstruction enables me to readily secure and as easily remove the valve when necessary, as it is simply caught between the two side plates of the carrier when brought and secured together. The nut E is carried between the other ends of the carrierplates, and it is not only pivotally mounted, but is ad] ustably secured by a sliding mount, formed by fitting its side pins e in elongated slots c', made in the carrier-plates. Through cap B passes centrally the operating-screw F, the lower threaded end of which is seated in nut E.
A point of arrangement to be noticed is this: The valve-seat a of the exit-opening a.
.is carried inwardly into the shell very slightly,
and the arm b of cap B is close to the inner wall of the shell, so that the pivotal center h of the valve-carrier is as nearly in the vertical plane of thevvalve-seat as possible. The object of this is to close the valve to its seat at that portion of its arc movement which is nearest the horizontal, its deiection being less at that point than at other points, and therefore the valve is enabled to come up to its seat perfectly true, and prevents any great sliding or scraping motion of the valve on the seat. By raising the screw F the valve is withdrawn from .its seat, rising through a backward arc (the sliding and pivoted nut permitting) until it reaches an inclined position. (Shown in dotted lines.) In this position it has fully opened the exit a, and at the saine time serves as a deiiector to better direct the stream into and through theexit. Then upon closing it will not catch any debris, pebbles, sand, or other extraneous matter having a tendency to wear it out or injure it, for it closes squarely and perpendicularly to its seat.
In order to properly hold the screw in the cap B and to avoid having to make or secure to it an expensive bearing-collar, I have the following construction: On the under side of the cap is formed around its central hole, but of larger diameter, an internally-threaded iange G. Into the socket formed by this iiange I drop the two-partor divided ring H, which seats itself in an encircling groove f, made in the screw-body. Then into the flange is screwed the externally-threaded gland-nut I, the inner end of which passes behind the ring, while an internal flange/ of said nut bears up under the ring, whereby said ring is held in its seat. Then upon the lower end of this nut is screwed the cap-nut J, between the head of which and the flange@- a suitable packing K is confined.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a nre-hydrant, and in combination with the hydiant-cap and the valve-operatin g screw having an encircling groove, the means for holding the screw in the cap, consisting of the two-part or divided ring fitting the groove of the screw, the housing-fiange on the under side of the cap, and the gland-nut with internal ilange fitting in the housing-ilaiige and IOO confining the ring to its seat, substantially as ring to its seat, the cap-nut on the gland-nut, 1o described. and the intervening;VV packing, substantially 2.
