HYDRANT.

SPECIFICATION forming part of Letters Patent No. 681,901, dated September 3, 1901.

Application filed June 13, 1901. Serial NOEBLLASG. (No model.)

To all whom it may concern,.-

Beit known that I, OWEN L. WHITEMAN, a citizen of the United States, residing at Coxsackie, in the county of Greene, State of New York, have invented certain new and useful Improvements in Hydrants, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to hydrants, and par- 1o ticularly to such a structure employing a movable gate-valve.

The invention has for an object to construct this valve and the guiding means therefor so that it shall be adjustable in dierent directions in order to fit upon its seat and be clamped thereto when the valve is closed.

A further object of the invention is to provide mea-ns carried by said movable valvegate for positively and automatically operzo ating a drip-cock to permit the escape of Water from the casing of the hydrant, which is necessary when the valve is closed upon the seat, and which drip-cock should be positively closed when the valve is opened to ad- 2 5 mit water into the hydrant-casing.

Other objects and advantages of the invention will hereinafter appear in the following description, and. the novel features thereof will be particularly pointed out in the ap- 3o pended claims.

In the drawings, Figure l is a vertical section through the hydrant with parts broken away. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a rear elevation of the valve-disk of Fig. 2, with the coverplate at the rear of the casing removed and also the connection with the valve-rod. Fig. 4 is a detail perspective of the nut adapted to be carried by the valve-disk. Fig. 5 is a 4o detail elevation of the drip-valve connection to be operated in the vertical movement ofl the valve-disk, and Fig. 6 is a side elevation of the stem-nut. v

Like letters of reference indicate like parts throughout the several figures of the drawings.

In the drawings the letter A designates the vided with a cap A2, carrying any desired construction of valve-operating means adapted to vertically reciprocate the valve-rod B, which at its upper end is provided with a threaded portion B' and at its lower end is connected with the valve-disk by means to be hereinafter described. For the purpose of reciprocating this rod B the cover has applied thereto a rotatable collar A3, having a wrench-hold at its upper end and a threaded portion A4 at its lower end, adapted to en-` gage the threads B' of the valve-rod, which collar is suitably mounted in a packing-box, as shown. All of these features of construction, however, are well known in the art and have not been very particularly described, as the invention is in no wise confined thereto.

At the lower end of the valve-casing A the elbow O is applied and is provided upon one face with the bearings C' for the valve-disk D and upon the opposite face with an opening C2, adapted to be closed by the' coverplate O3, which may be adapted to carry the drip cock or valve E. The inner face of this elbow is also supplied at opposite sides with4 the guideiianges C4 at the upper portion thereof, tapering toward each other and 4terminating at the upper ends of the guides C5, which are adapted to receive and guide the lugs D' at opposite sides of the valve-disk D, so that the same may be withdrawn or inserted from the upper portion of the casing' and readily guided into position. The coverplate C3 is provided upon its inner face with a beveled or inclined lug O6, which forms an abutment opposite the disk D in order that the same may by the wedging action be forced into rm contact with its seat C'. The valve-disk D is carried by the stem-nut F, particularly shown in Fig. 1t, which nut is provided at its lower portion with a curved face F', adapted to seat in the socket D2, provided one face of the disk D should be secured Vtherein by means of a suitable device-'for instance, a set-screw D3, entering a recess in one end of said nut. Opposite the curved face F' a wedging-face F2 is provided, which is curved longitudinally and at a right angle to the face F', while said face F2 is also beveled slightly inwardly from the upper edge downward in order to coperate in its wedging function with the lug C6. Extend- IOO ing upward from the center of the lower, portion of this nut is the' cylindrical stemkFg, adapted to travel within the socket D4 from the face of the disk D, which stem terminates in the threaded connection F4, by which the valve-rod B is secured thereto. It will be seen that the valve is capable of oscillation in relation to the stem-nut in a horizontal plane by reason ot' the socket D2, and the valve and nut are both capable of oscillation in a vertical plane by reason of the threaded connection between the nut and the valvestem B, while the nut is retained in its relation with the valve at all times by4 a setscrew D3. It will also be observed that the curved face F2 of the nut is adapted to rock upon the wedge-lug C, thus permitting the necessary movement for the valve to accurately iit its seat, while the downward pressure upon this face produces a wedging action to firmly hold the valve in contact with its seat.

For the purpose of operating the drip-valve E, which may be of any desired construction,

but is here shown as a rotating cock, I have provided upon one face of the valve-disk D a track or way G, which at its lower portion extends in a vertical plane and at its upper portion G' is curved into a horizontal plane, while the lower portion of this track or way is suitably tapered, as at G2, to permit the same to pass over an operating arm or lever II, extending from the drip-valve. This lever is provided with a crank-arm H, carrying at its outer end a friction-roller H2, adapted to ride in the way G, while the opposite end of the lever is provided with the 1 perforated sleeve H3, adapted to tit over the apertured drip-pipe E', whereby the aperture in the collar H3 may be brought into alinement with a similar aperture in the drip-pipe lo permit the escape of water from the casing,vor when said apertures are thrown out of alinement the discharge of water through such pipe will be stopped.

In the operation of the valve it will be seen that when the valve is opened by rotating 1 the -collar A3 the disk D will travel upward between-the guides C5, and in its upward movement the lever from the drip-valve will be thrown into a vertical position, as shown by dotted lines in Fig. 3, so as to close this valve and permit the discharge of water only from the hose connection A' of the casing. In the return movement to close the valve the disk travels downward, throwing the lever H into position shown by full lines in Fig. 3, so as to open the drip-valve when the valve-disk D has reached its seat. During this downward movement the inclined face F2 of the stem-nut is riding in contact with the beveled lug C6, thus forcing or wedging the valve-disk toward its seat C. It will be further observed that the stem-nut has the transverse horizontal extension thereof provided with the curved face F extending transversely of the extension and the curved` face F2 extending longitudinally of 'the extension. The first-mentioned face permitsa rocking of the valve upon the stem-n ut, while the latter permits a bodily rocking of the nut and valve upon the wedge-lu g, while a movement of the valve-disk upon the rod B may be effected as before stated.

It will be obvious that chan ges may be made in details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claims.
