IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent No. 200,121, dated February 12, 1878 application filed December 15, 1877.

T0 all whom it may concem:

Be it known that I, ALVAH 0. AUSTIN, of Oakland, Alameda county, Oalifornia, have invented an Improved Hydrant, of which the following is a speoification:

This hydrant is designed to improve upon the arrangement and oombinaton of the parts necessary to open and close the valve, the valve itself and the shell or standing column being similar to other hydrants in use.

Figure 1 is a sectional elevation, and Fig. 2 is a plan of sleeve and stuffing-box.

In Fig. 1, A is an elbow. connecting with the street-main. B is the standing column or body of the hydrant. 0 is a cap or cover bolted thereco. Dis a nozzle for the escape of the water when the valve is open, and to which fire-hose may be attached. E is the valve, having a metal seat, F, he1d secnrely in the recess formed to receive it by lead packing. G is the valve-stem, secnred in ordinary manner to the valve, but screwed into the sleeve H above, and afterward pinned by the pin 1). This sleeve H is not made With its exterior perfecfly round, except for about omehalf an inch at its upper end, but should be ootagon-shaped, as shown in dotted lines, Fig. 2, so that it may not revolve in the stuffingbox I when the screw-spindle J is turned around. The stuffing-box I is screwed into the annular fiange K, cast to the interior of the hydrant-oolnmn.

The gland L may be round where it fits the stuffing-box, but partakes of the shape of the exterior of the sleeve H where it rests against it. The screw-spindle J sorews into the sleeve H, and passes out through the cap of the hydrant C, terminating in a entagonshaped end, upon whieh a wrench or spanner may be applied. This spindle J has a collar, M, npon which the gland N is screwed clown, so that it may be held from moving vertically when turned around. About one-half of an ineh of the top of the sleeve H being made round, th us 1nakin g proj ectin g flanges beyond its octagon-shaped sides, it can never entirely pass through the stuffingbox gland, but Will be stopped when these projections strike upon the gland. There is no danger therefore of wi ndin g the screw altogether out of the sleeve.

Near the bottom of the hydrant, at 0, a screw-plug may be provided, to draw off the water from above the valve when the hydrant is not in use. This precaution is only nocessary in cold, freezing climates. V

The sleeve H should be lubricated internally as well as externally. For this pnrpose an oilhole is provided at 0.

The operation of the hydrant is as follows: The wrenoh or spanner being applied to the end of the screw J, the sorew is wound out of the sleeve H. N OW, as the screw-spindle cannot itself move up or down, it follows that the Sleeve H must, oarrying with it the valvestem and valve to whioh it is attached. Thus the valve is retired from or brought bac]; to its scat, and the water admitted to or shut off from the hydrant, as the case may be, without the neoessity of removing the cap.

What I claim as my invention, and desire to secure by Letters Patent, is as follows:

As a means of operating the valve of a hydrant, the oombination, with the sorew-spindle J, acting as prime mover, of a polygon sleeve or nnt, H, guided in a stuffing-box, I, having a gland, L, fitting the exterior of said sleeve H, the said sleeve H being connected with the valve-stem G, as herein set forth, and for the pnrpose described.

ALVAH 0. AUSTIN.
