Specification of Letters Patent.

Patented Feb. 28, 19H.

Applcaton'led July 11, 1910. Serial No. 571,443.

To all 'whom 'it may concern:

Be it known that I, OLE O. STORLE, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful improvements in Hydrants, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates more particularly to outdoor service connections with underground water mains. its main objects are to insure and maintain a tight closure of the valve and thus avoid leakage and waste of water and the bursting of the hyd ant by the freezing of water leaking into it; to facilitate the operation of the valve; and genn erally to improve the construction and operation of devices of this class.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and defined in the claims.

ln the accompanying drawing like characters designate the same parts in the several figures.

Figure l is a central vertical sect-ion on the line l l, Fig. 2, of one form of hydrant embodying the invention; Fig. 2 is a horizontal cross section of the same on the line 2 2, Fig. l; Fig. 3 is an inverted plan view of the waste valve; and Fig. t is a partial central vertical section of a modified form of hydrant also embodying the invention.

Referring to Figs. l to 3 inclusive, the hydrant comprises a tubular body preferably formed as shown in Fig. l, of two sections a and 7;, which are flanged and bolted together. The upper section a, which projects above the ground, is provided at or adjacent to its upper end with one or more discharge nozzles or connections c for attaching hose thereto.

The lower section Z) is formed with a lateral inlet connection d opening into an inlet chamber' e between two alined openings, one above and the other below or on opposite sides of said inlet connection by which the hydrant is coupled to the water main below ground. The openings above andbelow the inlet chamber e are formed or provided with coaxial valve seats f, which for the purpose of renewal and to facilitate manufacture, are preferably made separate from the body of the hydrant and are inserted and calked with soft metal rings g or otherwise secured in undercut grooves in the inwardly projecting di aphragms or partitions which detine the inlet chamber c on the upper and lower sides thereof.

An axially movable tapering tubular valve 7L. is itted in the seats f so as to control communication between the inlet chamber e and the passage in the tubular body leading upwardly therefrom to the discharge nozzles or connections c. An operating stem for opening and closing the valve extends therefrom upwardly through the tubular body and projects at its upper end which .is squared or formed with a wrench head, through a. stuffing box at the top of the body, as shown in Fig. l. For convenience in making and assembling t-he parts of the hydrant this stem is preferably 1 ade as shown, in sections. The lower section j, which has central bearings 7G and Z at its upper and lower ends in the body of the hydrant, is threaded and engages with central spider nuts m in the upper and lower ends of the valve. rlhe upper section 11. passing through the stuffing box z', is formed at its lower end with a socket which. engages with the squared upper end of an intermediate section 0, which is squared at its lower end and connected by a sleeve y? with the squared upper end of the threaded section j'. To hold the threaded section y' in place and prevent endwise movement thereof when the sections of the hydrant body are assembled, it is provided just below the bearing lc with a collar or shoulder g.

The valve is prevented from turning with the operating stem by a projection r at the upper end thereof engaging with a vertical guideway s formed in one side of the upper section a of the tubular body, which is enlarged at its lower end to receive the valve when it is opened.

To provide for escape of water from the hydrant when the valve isi closed and to prevent the bursting of the hydrant in cold weather by the freezing of water therein, a waste or drain opening or connection t is provided in the lower part of the body, and a valve u is arranged to close this opening or connection when the main valve t is opened. rlhe valve u, which may be made as shown, to close by gravity, is formed or provided with an arm e, which is fulcrumed on the step bearing Z and'projects into the path ot the main valve 71` so that the closing of the latter will open the valve u. The operating stein ot the main valve passes loosely through an opening in the arm o; to hold it in place and said arm is formed or provided on each side of the opening with tulcrum points orprojections fw, as shown in Fig. 3, and indicated by dotted lines in Fig. l.

In the operationot the hydrant, to open the main valve 7L. the operating stem is turned with a wrench in the prop-er direction to withdraw the valve upwardly into the enlarged lower portion of the upper section a of the body, as indicated by dotted lines in Fig. l. This movement of the valve opens both the ports above and below the inlet chamber e, whereupon water flows first through both ports, the water passing through the lower port into the drain chamber in the lower part of the hydrant and thence through the tubular valve into the upper part of the hydrant. Then the main valve is fully open, as indicated by dotted lines on Fig. l, the water flows directly upward through the upper port, and bot-h through and around the valve into the upper part of the hydrant, as indicated by arrows. When the main valve h is withdrawn from its seats in opening it, the waste valve u is released and closes the opening or passage in the waste connection t. The main valve h being completely surrounded by the inlet chamber c, is balanced laterally to whatever head or pressure it may be subjected in said chamber, and forming an open passage between the upper and lower part-s of the hydrant thro-ugh the inlet chamber, is substantially balanced endwise, so that it is easily opened and closed and subjected to even and uniform wear. l'n closing, the stem is turned in the opposite direction, moving the main valve downward to the position in which it is shown by full lines in Fig. l, the tapering working faces ot' the valve engaging both seats f and closing the upper and lower ports simultaneously. Any wear of the valve and it-s seats is compensated for by a further traverse of the valve in closing, so that a tight closure of the valve is insured under all conditions, and the effective life of the valve is prolonged indefinitely.

Referring to Fig. 4, showing a. modiiication of the hydrant, a by pass x is formed in the upper and lower sections a and o of the body around the inlet chamber e and a chamber g/ above it, into which the main valve 7L. is withdrawn in opening it. In this form the main valve is reduced in diameter between its tapering faces which close against the seats f above and below the chamber c. In other respects the construction and arrangement of parts is or may be substantially like that shown in Fig.

l. The operation ot this form of hydrant is substantially like that of the form shown in Fig. l, except that when the main valve is fully opened, the water iows, as indicated by arrows, from the inlet connection (Z downward through the lower port of the inlet chamber into the lower part of the hydrant, thence upward through the by pass :c into the upper part of the hydrant to the discharge nozzle or nozzles, which may be like those shown in Fig. l. Tith this form ot' hydrant the sweep of the water through the lower partthereof will take up and carry off any sedimentor foreign matter which would otherwise settle and remain in the bottom of the hydra-nt.

Various changes in the minor details of construction and arrangement of parts may be made without depart-ing from the spirit and scope of the invention.
