HYDRANT.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom it may concern:

Be it known that I, EDGAR R. SToDDAnn, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Hydrants, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in hydrants, and especially in hydrants for water systems in which a high pressure is maintained; and its object is to provide a cheap and durable construction in which a doubledisk wedge-valve is used to close the main leading to the hydrant and which permits of the turning of the hydrant to face in any desired direction relative to its connection to the main.

It is also an object of the invention to so construct the hydrant nozzles and their valves that they may be readily detached and to so construct these valves that they will not drag over their seats in opening and become worn.

A further object of the invention is to pro vide suitable means for automatically draining the hydrant and stand-pipe and to provide the device with certain other new and useful features and the particular construction and combination of parts, all as hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a device embodying the invention with a portion broken away to show the drain-valve; Fig. 2, an elevation at right angles to Fig- 1, showing the same partially in section; Fig. 3, a central vertical section on the line 3 3 of Fig. 4 of the upper end of the hydrant, and Fig. 4 is a horizontal section of the same on the line 4 4 of Fig. 3.

As shown in the drawings, 1 is the watermain, opening into a valve-casing 2 forming an elbow, into the upwardly-facing open end of which is screwed one end of a wrought-iron pipe forming the stand-pipe 3, which may be cut the proper lengthaccording to the depth at which the main is laid, and within this oasing 2 is a double-disk gate or Wedge-valve 4,

of the ordinary construction, the stem 5 of which extends upward adjacent to the standpipe 3 and hydrant-casing 6, which casing is screwed upon the upper end of said pipe. On the hydrant-casing is a loose ring 7, which forms a supporting-flange to engage and rest upon the pavement or other support, and through an opening in this ring the valve stem or rod is passed to guide and support said stem, the upper end of the same being extended through an ear 8, detachably se cured to the upper end of the hydrant-casing. By this arrangement the hydrant may be turned upon the upper end of the stanctpipe within the ring 7 to extend the nozzles in the most desirable direction relative to the watermain.

The hydrant-casing 6 is cast in one piece, the dome or rounded upper end bein an integral part of the casing and provided with a hand-hole 9 and suitable openings for the desired number of nozzle members 10, which i are slipped through said openings from the inside, the hand-hole permitting of such insertion, and locked therein by lock-nuts 11 on the threaded outer ends of said nozzles, the nuts engaging the outer surface of the casing, and flanges 12 on the inner ends of the nozzles engaging the inner surface thereof. The screw-threaded outer ends of the nozzle members project some distance beyond the lock-nuts when said nuts are turned up and form nozzles for the attachment of hose.

Formed integral with the inner end of each of the nozzle members are the Ways 13, which extend laterally therefrom at right angles to the axis of said member, and longitudinally movable on said ways is a valve 14, engaged and operated by a screw-stem 15, extending outward through the casing and through a stuffing-box 16. The inner end of each nozzle member is beveled off to form a seat 17 for the valve, extending at an angle to the ways or to the line of travel of said valve, and each. valve is beveled at the same inclination to its line of travel, so that the two surfaces willcorrespond and form aperfect seat. The surface of the valve-seat at its side from which the ways extend being farther from the plane of travel of the valve than the opposite side of said seat,when the valve is moved on the ways to close the nozzle, it does not contact with the seat until it has covered the opening, or, that is, the valve closes the opening and comes to its seat at the same time, and therefore in opening or closing the valve it is not worn by dragging over its seat and is very easily operated.

Each of the valve stems 15 is preven ed from longitudinal movement by an integral collar 18, which lies within a recess in the casing and is held therein by a socket 19, screwed into a recess of larger diameter and engaging the outer side of said collar. Within the socket 19, which is internallys crew-threaded, is a follower 20, loosely sleeved on the stem and provided with a flanged inner end to en gage and compress the packing 21 in the bottom of'the socket, said follower being forced into the socket by a cap 22, which is sleeved on the stem and screwed into the outer end of said socket. Thefollower is of such diameter and length that it is engaged by the cap at its extreme outer end only, and therefore the frictional contact between the cap and follower will not be great enough to turn the cap should the packing and follower be turned by the turning of the stem. 7 To permit the water contained in the standpipe and hydrant to run out after the main valve 4 is closed, a valve 23 is provided in a chamber located adjacent to the main valve and communicating through the valve-casing with the stand-pipe. Said valve 23 is normally held open by a spring 24, said spring being strong enough to hold the valve open against the weight of the water in the stand-pipe and hydrant when the main valve is closed, but not strong enoughto hold it open when the said valve is open and pressure is on the hydrant.

To admit air to the hydrant, so that the water held in said hydrant and stand-pipe by the closing of the main valve will drain out when all of the nozzle-valves are closed, a vent is provided in the top of the hydrantcasing, consisting of a plug 25, which is screwed into an opening in the casing and formed with a chamber 26 and passages 27, leading from said chamber through the sides of the plug. The bottom of, the chamber forms a seat for a valve 28, and in the tops of the plug is a recess 29 for a nut or head on the upper end of the valve-stem 30, which stem extends upward through and is guided in the plug. The outer end of the recess is closed by a screw-plug 31 to prevent tampering with the valve and to keep out the dirt.

When the main valve 4 is opened, the ventvalve 28 will be closed by the water-pressure and prevent the escape of the water through the openings; but as soon as the main valve is closed and the water in the hydrant is no longer under pressure said valve 28 will open and admit air to the hydrant.

Having thus fully described my invention,

what I claim-is- 1. The combination of a valve-casing, a stand-pipe extending upward from said casing, a valve in said casing the stem of which extends upward adjacent to the stand-pipe, a

hydrant attached to the upper end of said stand-pipe to turn thereon, and a ring sleeved on the hydrant and having an opening through which the valve-stem passes.

2. The combination of a hydrant-casin formed with an inte ral closed upper end anc having openings and a hand-hole in its sides, nozzle members screw threaded at their outer ends and provided with flanges at their inner ends to engage the inner side of the easing, lock-nuts on the nozzles to engage the outer side of the casing, ways integral with the inner flanged ends of the nozzle members, valves guided on said ways within. the casing to engage and close the inner ends of said nozzle members and valve-stems to operate said valves extending outward through stufi ing-boxes on the casing.

3. The combination with a stand-pipe and hydrant, of a drain-valve in the lower end of the standpipe, and a vent in the upper end of the hydrant consisting of a plug chambered at itsinner end to form a valve-seat and recessed at its outer end and formed with lateral passages leading from said seat, a valve to engage said seat a valve-stem for said valve uided in said plug and provided with a head- Within said recess, and a plug to close the outer end of said recess.

4. The combination with a valve-casing provided with a lateral chamber, a disk valve in said casing, a valve-stem extending vertically upward from said valve, a drainvalve in said chamber, a spring to normally hold said valve open and to allow the valve to close when the disk valve is opened, a standpipe secured to said casing, a hydrant-casing secured to the upper end of said standpipe and providedwith openings and a handhole, a ring loosely sleeved on the hydrant through which the vertical valve-stem extends, nozzle members secured in the openings in the hydrant-casing, valves to close said nozzles, and a vent in the upper end of the hydrant casing consisting of a plug formed with a chamber and lateral openings, and a recess in the top, a valve to closethe lateral openings, a valvestem extending upward into the recess and provided with a head therein, and a screw-plug to close the recess.

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