FIR-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 428,578, dated May 20, 1890.

Application filed July 18, 1889. Serial No. 817,913. (No model.)

struct and so hang the valve of a fire-hydrant that said valve when open will swing completely ont of the water-way and will therefore no t offer any obstruction to the free flow.

of the-water from the service-pipe through the goose-neck and up into the stand-pipe of the hydrant, a further object being to provide for the ready fitting of the soft-metal valve-seat to its bearing on the stand-pipe of the hydrant. These objects we attain in the 4 manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure -l is a vertical section of a fire-hydrant constructed in accordance with our invention. Fig. 2 is an enlarged sectional. view of the lower portion of the hydrant, illustrating our improved device for hanging the valve; and Fig. 3 is a sectional view, on a still larger scale, illustrating the method of applying the soft metal valve seat to the flange at the bottom of the stand-pipe of the hydrant.

A represents the usual goose-neck to be applied to the service-pipe of the hydrant, andB is the casing, usually termed the frostcase, this casing being secured at its lower end to the goose-neck, and extending upward therefrom to a point above the level of the roadway or sidewalk, the upper end of the casing being flanged for the reception of a flange a upon the stand-pipe D of the hydrant, and this fiange a being secured to the flange of the casing B, so as to cause a packing-ring b, carried by the lower end of the stand-pipe, to seat itself firmly upon the top of the goose-neck around the opening therein, and thus form a water-tight joint between the goose-neck and the stand-pipe. Around the lower portion of the stand-pipe is formed an inwardly-projecting flange d, which carries a soft-metal ring flforming a seat for the valve F, the latter being constructed in any desired manner, but being provided o n the under side with lugs g, which are connected by a link e to lugs h on the lower end of the stand-pipe. The valve-operating rod G is suitably guided in cross-bars in the standpipe and is threaded at its upper end for adaptation to a nut m, which is vertically confined to the hood or cap at the top of the stand-pipe, but is free to turn therein, so as to effect the lowering or raising of the valverod and the opening or closing of the valve. Owing to the arc of a circle in which the valve swings in opening and closing it is necessary to have a laterally-yielding oonnection between the valve-rod and the valve; hence we connect the valve to the lower end of the valve-rod by means of a link n, which permits the swinging of the valve without imparting any side-thrust to the valve-operating rod. Owing to the swinging movement' of the valve, the latter when open is entirely out of the way of the water passing through the goose-neck and into the stand-pipe, as shown by dotted lines in Fig. 2, the valve, however, closing `inwardly or in the direction of the pressure of water, so as to form a tight joint with the valve-seat and prevent the passage of water when the valve is closed.

The valve-seat f has on its upper face a rib p, which is expanded into an undercut groove s in the inwardly-proj ecting flange d of the stand-pipe, so that said valve-seat is firmly conned to the flange.

In order to permit the ready application of the valve-seat to the flange, said valve-seat is in the first instance formed with the upwardly-projecting split rib p, and the groove s in the under face of the flange d has a central V-shaped tongue t, which as the valveseat is moved vertically in order to apply it to the flange enters the slot in the rib p and expands the same into the undercut groove, as shown in Fig. 2.

It will be observed that the stand-pipe, with` its valve, may on removing the bolts which;

the lower end of the stand-pipe and its valve without disturbing the fixed or permanent portion of the hydrant or necessitating' any break in the pavement or (ligging up ot the street adjacent to the hydrant.

In order to provide for the escape from the stand-pipe of the water remaining therein when the valve has been closed, there is at one side of the standpipe and close to the bottom of the same an opening a', which, when the valve l? is open, is closed by means ot a weighted and pendent valve y, a toe upon the latter being, however, struck by the valve F as it rises to its scat, se as to open said valve y, as shown in liig. 2, and thus permit the water in the stand-pipe to escape into the casing l, and thence through suitable openings in the latter into the earth surrounding the hydrant, so as te prevent freezing ef the water in the stand-pipe of the hydrant when the temperature is below the freezing-point.

`\\"hi1e the use of the link n is preferred, it is not absolutely necessary7 as there may in seme cases be suilcicnt lateral spring in the valve-rod Gto permit of the jointing of the valve directly to the lower end of said rod, and in eases where it is not necessary te remove the standspipe and its valve together the link c may be hung to the goose-neck instead of to the stand-pipe, if desired.

Having thus described enr invention, we claim and desire to secure by Letters Patentl. The combination of the goose-ncck and the stand-pipe of the hydrant, the lai-terhaving a seat at its lower end, with a valve adapted to said seat and closing upward against the same, a valve-operating red extending up through the stand-pipe and connected to the top of the valve, and a link connected to the valve and extending laterally to a pivot-lug on the lower end of the stand-pipe at one side of the valve, substantially as specified.

The combination of the valve-seat bearing having a grooved 'flange and a wedgeshaped tongue projecting point first into the groove, with the valve-seat having a rib expanded into said groove by the tongue, substantially as specified.

The combination of the goose-neck, the outer casing secured thereto at the bottom, the stand-pipe secured to said outer casing at the top and having at lthe bottom a pack ingr-ing seated on the goose-neck, the valve adapted to a seat at the bottom of the standpipe, and a laterally-projeeting link carrying the valve and hung te abearing on the standpipe at one side of the valve-scat, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
