HYDRANT.

SPECIFICATION forming part of Letters Patent No. 377,357, dated January 31, 1888.

Application tiled September 12, 1887. Serial No. 249,512. (X model.)

To aZZ whom it may concern.-

Be it known that I, EKINS HAND, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Hydrants; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application. to The object of my invention is to prevent water from standing in the hydrant when the supply is turned off, and the consequent freezing of the same in cold weather.

To this end my invention consists in the con- 1 struction and arrangement of the lower part of the hydrant, as hereinafter more fully described aud definitely claimed.

In the drawings, Figure 1 is a central vertical section of the lower portion of the hydrant.

Fig. 2 is a cross-section of the same in line 00 x of Fig. 1. Fig. 3 is an end view of the cut-off piston. Fig. 4 is a View of the screw-guide.

My improvement relates, particularly, to the lower end of the hydrant, where water is admitted from the main and where the waste water is discharged.

A indicates the casing, provided with a nozzle, B, through which the induction'water is admitted from the main.

0 is the cut-elf piston or plunger for controlling the admission of the water. It consists of a circular head, (1, provided with a packing, I), that fits a seat at the inner end of the nozzle, and legs a c, that rest in the nozzle and form guides, and a stem, (1, extending back across the inside of the casing, as shown in the drawings.

G is a screw passing in through the back of the casing, its inner end being smooth and passing into a hole in the end of the stem (Laud serving as a guide to hold the piston in place as it moves forward and backward.

E is a rod or bar extending down vertically through the hydrant, passing through a slot, f, in the piston-stem d, and provided above the slot with a wedgeshaped lug, h. Vhen the rod is forced down, the wedge-shaped lug will force the piston out, so as to seat it against the nozzle B, and thus cut off the flow of water. \Vhen it is raised again, the piston will open to allow the water to flow. The end of the screw G passes into the slot 1 ol' the pistonstem d and serves as the backing or fulcrum for the rod to act against. By turning said screw up or back more or less, the throw of the piston will be correspondingly changed.

It will be seen that the screw performs the double purpose of afulerum for the operatingrod and a guide and support for the piston, which slides freely thereon. The legs 0 c, reaching into the nozzle, serve as guides to the front end of the piston.

H is a valve at the bottom of the hydrant to discharge the waste water. It strikes upward against a seat, at, to cut off the flow and opens downward to discharge the waste.

r is a stern of the valve, that passes down through a bearing, 19, and s is a spiral spring around the stem for throwing the valve up.

I is a collar containing the valve, said collar screwing on a nozzle, 7;, at the bottom of the hydrant, and having a thread at its lower end, on which screws the discharge-pipe. The upper end of valve H extends above the bottom of the hydrant, as shown in Fig. 1, and the rod or bar E projects below the piston, and these parts are so relatively arranged that when the rod E is forced down sufficiently to close the piston G and cut off the ingress of water from the main the lower end of saidSo rod strikes the valve H and opens it, so as to discharge the waste water in the hydrant. By this means the hydrant is always kept free of waste water when the flow from the main is cut off.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s

In a hydrant, the combination, with the casing provided with an inductionopening, 0 of the piston 0, provided with. head a and slot f, the rod E, provided'with wedge-shapedlug 71, passing through the slot of the piston-stem, and the supporting and adjusting screw G, on which the piston slides, as herein shown and 5 described.
