HYDRANT-VALVE.

SPECIFICATION forming part of Letters Patent No. 470,571, dated March 8, 1892.

Application filed November 3, 1891. Serial No. 410,742. (No model.)

To all whom t may concern.-

Beit known that l, JOHN D. HOOKER, of the city and county of Los Angeles, State of Galifornia, have invented certain new and useful Improvements in I-Iydrants; andIhereby declare the following specification and drawings forming a part thereof to be a full, true, and exact description of my invention.

M yinvention relates especially to that class of hydrants employed for irrigating land; and it consists in so constructing the valves that they are accessible for inspection, renewal, or repairs without removing or separating the main parts of the hydrant and Without shutting off the water therefrom; also, in acheap and simple construction of the parts, that permits a wider application of such hydrants and adapts them for use by the unskilled.

In the drawings, Figurel is a plan view on top of one of myimproved hydrants, and Fig. 2 is a central section on line of Fig. 1.

Similar letters of reference on the two views are employed to indicate corresponding parts.

A is the main body or casing of the hydrant, formed in one piece, except the removable plate B. The valve C is operated by the screw D, having a nut and bearing at E in the main casing A and a hand -Wheel L at the top. The stand-pipe F extends upward to a convenient height from the underground main conduit and forms a column or support for the hydrant at the top. Water rises through this pipe F and, passing under the valve C when raised, is discharged at the oval spout G. The main caseA is preferably made rect-` angular in shape, as shown at Fig. l, to accommodate a similar form of the valve O (indicated in dotted lines in Fig. l) and to prevent the valveA from turning as it is adjusted up or down. The valve O consists of a main plate H, recessed and grooved on its lower face, as shown at O, to receive a metal plate I, to which plate is'riveted the faces J, made of leather or other lexible material that will fit down closely on the seat K, and thus form a Water-tight joint. The screw D has at its lower end an extension a, fitting loosely in a boss M of the valve-plate H. This extension has around it a groove in which is placed a crosspin e, so that the valve is lifted as well as pressed down or shut by the action of the .screw D. The extension ctof the sc-rewD fits loosely in the boss M of the valve C, so as to permit some oscillation of the valve, thus insuring a uniform and perfect bearing on the valve-seat K. In case the faces J of the valve C need adjustment or renewal, the hand-plate B is removed and the plate I, with the facing J, can be withdrawn from the main plate I'I and taken `out through the aperture N, or, what is commonly more convenient, the pin e is taken out and the valve C is removed through the aperture N, the water in the pipe F escaping mainly at the nozzle G, so as to not interfere with the removal of the valve C. It will thus be seen that my improved hydrant consists of only a few simple parts, all of which are easily accessible, and that no stop-valve is required at the bottom in the case of repairing and adjusting; also, that the construction involves only cutting screw-threads for the pipe F, screw D, and facing the seat K.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a hydrant, the combination, with the main casing having a lateral door or outlet and the horizontal valve-seat arranged within the casing, of a valve consisting of a main horizontal recessed member H, a iiat horizontal plate I, which is received into said member H, afacing J, secured b'low the member I-I and its plate I, and the vertical valvestem which passes upward throughabearing at the top of the main casing and has its lower end connected to the valve member II substantially as described.

2. In a hydrant, the combination of the main casing having at one side a door or outlet and at the other a discharge-nozzle G and having Within the casing a horizontal valveseat arranged at the entrance of the pipe F,

a valve consisting of a main horizontal rel cessed member H, a horizontal plate I, received into said recessed member, and flexible faces secured to the under side thereof, said valve operating in conjunction with the aforesaid valve-seat and the vertical screw-thread- ICO while the upper end is provided with an opaffixed my signature in the presence of two erating-wheel, substantially as described. Witnesses.

3. In a hydrant, the Valve O, composed of the main recessed plate H, the metallic plate 5 I, received therein, and the plates J, secured Witnesses:
