HYD RANT. i

SPECIFICATION forming part of Letters Patent No. 269,440, dated December 1 9, 1882. Application filed June 24, ISSQ. (No model.)

To all whom it may concern: Be it known that I, WILLIAu MCNAMAEA, of Cleveland, in the county of Uuyahoga and State ot' Ohio, have invented new and useful Improvements in Hydrants, of which the following is, adescription of the construction and operation thereof, reference being had to the annexed drawings, making` a part of this specitication, in which- Figure l shows an external side view otthe machine. Fig. 2 is a transverse longitudinal ysection. Figs. 3, 4, and 5 are detached sections.

Like letters ot' reference denote like partsin the several views. rIhe lower part or s cction ofthe `hydrant consists of a tubular shell, A, having on each ot' two opposite sides a conduit, B and C, respectively, which are in open communication with the shell at a and b, Fig. 2. In said shell is tted, in a water-tight manner, a tubular core, D, a detached longitudinal section .ot' which is shown in Fig. Said `core is made water-tight in the shell by means of packing c; Between said packing the surface otl the core is cut away, forming'an annular recess, e, Fig. 3. atf. Said recesses, when the coreisin theshell, form, with the sides thereof, annular chambers a and Z1', the purpose ot which will presently be shown. "itliin the core is movably fitted a hollow valve-stem, E, made water-tight therein by means of packing c'. To the lower end of the stem is secured a valve, F, having its seat inthe lower end ofthe shell A, t'or opening and closing the water-passage G. To the said valve-stem is secured a rod, H, passing through the tube or dry-pipe l, the lower end ot' which pipe is screwed into the'core, as seen at J, Fig. 2. To the above-described lower section of the hydrant is screwed a pipe, K, inclosing the tube l. The opposite end ot' the pipe is secured to the upper end ct' the hydrant, consisting ot' a shell, A', provided with a discharging-nozzle, B. In said shell A/is a cylinder, C', to the bottom of which is screwed the upper end of the tube I, thereby connecting the core D ot' the lower section of the hydrant with the cylinder C', as seen in the drawings. In said cylinder is fitted, so as to slide therein, a block,D/. 0n two sides ofthe block are ribs m, adapted respectively to fit and Slide in the slots n, made in the sides of the A similar recess is made in the core therein. The block is operated by a screw, E',

attached thereto by a flanged head, N, loosely iitted in the block, and which is prevented from being-pulled out therefrom by the flange of the head, adapted to engage a correspond-4 ing annular shoulder formed in the block,

thereby making a swivel-connection ot' the screw and head, substantially as lseen in Fig. 2. The screw is retained in the block by a nut, i, screwed therein, and to which nut the valve-rod H is attached, thereby connecting the screw E', by means of the rod, to the valve F for operating it. rIhe thread ot' the screw E isa coarseone and works in a nut, F', screwed into the shell A', as seen in Fig. 2.

The core D, above alluded to, is made up in sections 1, 2, 3, and 4,-as seen in Fig. 3, for the convenience of providing the core with 'packing. It will be observed that the several sections are connected to each other by screwjoints, and that between the collars ot' the sections the packing is secured.

I do not contne myself to the construction of the core as above described, as it may be otherwise made or modified without departing from its general structure.

The practical operation ofthe hydrant is as follows: The lower section of the machine is set down in the ground as low as the watermain', and is attached thereto by the pipe O in the usual way. As in ordinary hydrants, the `upper section is near the surt'ace ot' the ground. To this end the pipe K, &c., may be longer or shorter, as the setting of the hydrant may require. As shown in the drawings, the valve F is screwed down upon its seat, thereby shutting olf the water from the hydrant. Now, on turning the screw E in the proper direction the block D is drawn upward in the cylinder C', and with it the connecting-rod H, which, as a consequence, will lift the valve F from itsseat and allow the water to liow from the pipe 0 into the conduits B C, which passes upward therein and outl ofthe openings b b into the pipe K, up which it'passes to the discharging-nozzle B.

The passage of the water is in- I licated by the arrows. On turning down the screw E' the valve closes, shutting off the water from the hydrant. That which may be left in the pipe K and the conduits flows therefrom through the waste-hole u' into the hollow stem E of the valve, up which it passes to the venthole t', and is discharged therefrom into the annular chamber a', from thence to the outside of the hydrant, through the hole i', Fig. 1, in the side of the shell, thus leaving lthe hydrant free of water.

It will be obviousfrom the above that water cannot lodge in the pipe K when shut oi' from entering the hydrant; nor can it find its way into the dry-pipe I to the valve-rod H, the water being excluded therefrom by the close water-tight joints and packing. Hence the rod H is always kept dry, so that it will work easily, and not be liable to freeze up; nor can the water find its way above the discharging-nozzle,

as the packing r at the lower end of the cylinder closes the passage-Way about the pipe I, screwed in to the cylinder, said cylinder being screwed down upon its bearings in section A' by the screw-nut F', making the whole connection Water-tight.

In operating the hydrant the core remains stationary, the valve only beingthe part moved for opening and closing the hydrant. Hence there is but little frictional wearing ot' the parts in Working the hydrant, which may be used either with or without a stock. Should water leak from the pipe K around the upper' end of' the core, it can go no farther than to the annular chamber b', Fig. 2, and will run therefrom to the outside through the wasteholef' in the side of the core and a corresponding hole in the side of the shell, as seen atf' in Fig. 1.

In the drawings the waste-holes are shown as being both on the same side of the shell.

It is preferred to have one on each side, instead of both on one side.

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

1. In hydrants,in combination with the shell A and side conduits in open communication with said shell, the tubular core provided with exterior rings of packing and exterior annular recesses, forming, with the sides of the shell, annular chambers having waste-openin gs, substantially as described, and for the purpose set forth.

2. In hydrants, the core D, providedv with internal packing-rings, c, and annular recesses, in combination with the tubular valve-stem and valve, and shell A', having an outlet, B', substantially as described, and for the purposes set forth.

3. In combination with the tubular core, valve-stem E, and shell, the valve-rod H, pipe I, inclosing said rod, water-pipe K, connecting the shell A and shell A', in the manner substantially as and for the purpose specified.

4. In combination with the pipe I and valverod, the slotted cylinder, screw-stem E', loosely connected to the block D', shell A', and screw nut, substantially as described, and for the pury pose set forth.

5. The core D, consisting of sections connected to each other by screw-joints, and having interior and exterior packing and interior and exterior recesses, provided with wasteholes, in combination with the shell A and valve-stem, as and for the purpose specified.

In testimony whereofI ax my signature in presence of two witnesses.

WILLIAM MONAMARA.
