HYDRANT.

SPECIFICATION forming part of Letters Patent No. 247,869, dated October 4, 1881.

Application tiled April :27, 1881. (Model.)

To It whom it muy concern:

Be, it known that I, EDWARD M. ZEuBE, a

citizen ot'the United States, residing at Lewistown, in the count-y ol' )lit'iiin and Slate of Pennsylvania, have. invented certain new and uset'ul Improvements in Hydra-nts; and I do hereby declare the following to be. a full, clear, and exact description ot' the invention, suoli as will enable others skilled in the nrt to which it appertains to makeand use the sai'ne,reerence being had to the accompanying drawings, and to letters or figures ot'ret'erence marked thereon, which form a. partei' this Specification, and in which- Figure l is a front elevation ot the hydrant; Fig. 2, a longitudinal section thereof; Fig. 3, n perspective ofthe vulve and its seat detached from theeasing; Figa, :i cross-section through .r .r of Fig. 2; Fig. 5, a cross section through y y ot' Fig. 2; and Fig. (i a cross-section through ot' Fig. 3, Figs. 5 and G representing the ports as closed. Fig. T is an enlarged view ol' the. lower pai-t ot Fig. 2.

My invention relates to hydrants; and it consiss in the construction and the combination ot'partshereinat'ter particularly described, and then sought to be specifically defined by the claims.

In the accompanying drawings, thelett-er A indicates the top casing, and B the lower casing, one being passed into the other (screwed if desired) and further secured together by a screw, a, passed through thcouterlcasing into or against the lower casing. The recessed top C is fastened by screws or other means to the casin g A, and into its recess the upper end ot'- the hollow valve-rod D tits, that end of the rod being a T, detachable from the other section ot' the rod.

A spout, E, screws into the T-head oi' the rod, communicating with the interior of the saine, and passes through a slot, F, formed in the casing, and in which it is free to pla-y from right to left.

.Ontothelower end of rod D there is screwed the valve G, which is prevented by'a thumbscrew from turning on the rod. This valve has four or more openings in its sides for the escape ot' waste water, and several openings in its bottom for the inlet of water into the hollow valve-rod, and is provided on its outside with two or more lugs, H. The valve Gr tits into the valve-seat J, which is constructed with a threaded lozver exterior, so that it may be screwed into a box or extension, K, and with recesses L at its top, into which the lugs H ot' the valve may t., so that when they are turned till they strike against the shoulders of the recesses they will then turn the valve-seat with the valve,either connectingit to or disconnecting; it from the extension K, according as the parts are being put to their places for operation or taking therefrom for repairs.

The seatis provided with openings in its sides to correspond with those in the sides ofthe valve, tortheescapeot'waste water which passes ott through openings formed in the extension K next to the valve, as clearly shown in Fig. 2 ofthe drawings; and it is also provided with openings in its bottom for the inlet of' water to the valve. It is further formed with atlange, M, that is intended to bear down upon an elastic washer, c, which rest-s upon the seat N of the extension K, so that a close `joint will be made between the extension and valve-seat.

The openings in the sides of the valve and valve-seat are so arranged with reference to each other that when the valve is turned tolet on the supply of water the waste holes in the valve and its seat will be completely closed before any water is let on, so that there will be no waste ot' water while it is being drawn.

The valve and its seat are held together so that the bottom of the former will not come in contact with the bottom ofthe latter, and preferably so that th 0f the recesses in the seat and fapnsof the lugs to the valve will not rub against each other, whereby the friction caused by those parts rubbing together is obviated and the working of the parts made easier. That end I attain by making the outer circumference of the valve and inner circumference ot' its seat slightly tapering, as seen in Fig. 3.

The valve and its seat are held together by a boit, O, cast with the valve and made with a square shoulder, d, to pass through a square opening in the washer P, which has openings corresponding to those in the base of the valve, and a suitable packing to tit against the sides of the seat; a threaded portion, c, to receive a nut, Q, which holds the washer against the valve; a rounded portion, f, which passes through a corresponding opening in the base of the valve-scat and permits the valve to turn without turning` the seat; a square shoulder, 5 g, which passes through a corresponding opening in the valveplatc R, which has openings corresponding' to those in the base of the seat and through a metallic washer, S, whereby the plate and washer are caused to turn with the Io valve; and,fnally,a threaded portion,b,whch receives a nut, T, that presses an elastic washer, t', against the metallic washer' S and holds the plate R against the valve-scat and the valve and its sent together. The washer l) is made with a peripheral recess to receive an elastic tasteiiixxg,j, to make a close joint between the valve and the sides ot' its seat. The washer is detachable in order th at the packing in ay be the more snugly fitted zo in the recess thereof, and he clamped between the washer and bottom ofthe valve.

In operation, when the water is to be turned on, the spout E is grasped and pushed to one side, `which movement turns the hollow rod D z5 and carries with it the valve G and plate R, bringingthe openings in both opposite to those inthe base of seat J, so that the water which is received into the extension K through a lateral pipe from the source of supply, passes up 3o through the valve and hollow rod to and through thc discharge-pipe. Then the water is to be turned otf the spout is pushed back to its Erst position, which movement closes communication between the valve and its sea.t, and

3 5 excludes water therefrom. The waste water now passses off through the openings in the sides ot' the valve-seat and extension K, and this feature renders theh -'drant anti-freezing.

When the hydrant needs repairs the top is detached from the upper easingand the rod D then turned till the valve and its seat are unscrewed from the extension K, when the detached parts are lifted out from the easings A. and B,which remain undisturbed in theirplaces.

The recess in the top of the hydra-ut serves as a guide for the rod D, to steady the same.

IIavingdescribed myin vention, what Iclaim 1s- 1. The valve G, provided with lugs II and bolt O,cast therewith and provided with shoul* 5o ders dg, smooth rounded portionf, and threaded portions c h, in combination with seat J, provided with recesses L, washer P, plate It, and nuts Q T, the valve and its seat having waste-openingsarrangcdasdeseribed,snbstantially as and for the purposes specified.

2. The tapering valve G, provided with lugs H and bolt O, iu combination with tapering seat J, provided with recesses L, plateR, and nut T, substantially as set forth. 6o

3. The combination of seatJ, provided with recesses L and ange M,valve G, provided with lugs H and holt O, plate R., and extension K, provided with seat N, and elastic packing c, interposed between flange M and sent N, sub stantially as and for the purpose speciiied.

In testimony whereof I aix my signature in presence of two witnesses.
