SPECIFECATION forming p; of Letters Eatent No. 733,483, dated July 14, 1903.

Application filed February 20, 1902. Seria llo 94,870. (No model.)

To all 112710727, it m/riq cancer/2 Be it known that I, CLAUDE L. Howns, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hydrants, of which the following is a specification.

This invention has relation to'that type of hydrant which is provided with a hollow upright body having one or more lateral outlets, a main valve controlling the flow of water into the hydrant, and a separate valve for each of the lateral outlets.

The present invention has for its object to provide certain improvements in hydrants of the type mentioned, first, for the purpose of simplifying the construction of the same; second, for reducing the cost of maintenance, and, third, for rendering the interior operative parts of the hydrants accessible to enable them to be cleaned or repaired.

Referring to the drawings, Figure 1 represents a longitudinal vertical section through the hydrant embodying my improvement. Fig. 2 represents a section on the line 2 2 of Fig. 1 with one of the valves removed.

I have represented upon the drawings only that portion of the hydrant to which my invention particularly relates.

(0 indicates the body of the hydrant, which is provided with lateral apertures a, into which are screwed hose or steamer connect ing-nozzles Z). Preferably that portion of the nozzle engaging the body of the hydrant is provided with a tapering thread, as shown, and that portion which receives the capb or the hose-coupling has the usual screw-thread.

The cylindrical body a of the hydrant is cast with a plurality of interior walls of, which form elliptical valve-chambers 0, each chamber communicating directlywith an out let a or the nozzle Z) therein. The chambers 0 may be of different sizes, according to the volume of water to be discharged through the outlet, the walls which form said chambers extending from practically the top of the body to a distance somewhat below the out-.

lots. The top of each chamber and the top of the hydrant are closed by a stuffing-box plate (1, which fits snugly against the upper end of the walls a and upon the upper end of the main walls of the body a, said plate having a boss (1 fitting within the walls of the body to center it. The formation of the walls a provides a central chamber for the reception of the screw bar or stem 6 for the main valve. Said screw-bar extends into a sleeve 6, attached to the valve-spindle c and for the purpose of preventing the rotation of said sleeve it is formed with lugs or projections 6", which extend into parallel grooves or guides 0, in two of the walls a as clearly shown. In eaclrof the chambers c is placed a valve f, having at its lower end an elliptical shoe f, which is held in place by the washer f and the screwf- A rubber gasket is held against the shoe by a washer f and ascrewf. The walls which form each chamber are provided with an interior elliptical projection a, which forms a seat to receive the shoe f of the valve,this seat beinglocated'atorimmediately below the outlet a leading from said chamber. The chambers approximate an ellipse in crosssection; but the area of said cross-section is such as to be greater than the area of the outlet ct leading from each chamber, so that there is always a full supply of water delivered to each outlet when the valve is fully opened. The valves and valve-seats are similar in share to said cross-section, and therefore there is practically no reduction or retardation of the supply of water and the valves are prevented from rotating in the chambers. Each valve is provided, as shown, with a valve-stem f, which. is hollow and interiorly threaded for the reception of a longitudinallystationary screw bar or stem 9. The screw bars or stems e and 9 project upwardly through the stuffing-box plate in which they are jonrnaled and are squared at their ends for the reception of a tool by which they may be rotated. There are stufling boxes and glands for the stems to prevent leakage of water throu the apertures in which the said stems are located. By'virtue of this construction the walls of the chambers may be cast integrally with the body of the hydrant and are erfectly alined for the reception of the valves and the valve-spindles. The closure of the chambers by the stuffing-box plate reduces the number of parts very materially and provides for the easy accessibility of the valves for their renewal or for the purpose of cleaning them. Moreover, the plate may be removed to carry bodily with it the various valves supported thereby, and thus expose the entire interior of the casing.

As illustrated, the hydrant possesses the smallest number of parts, is simple in construction, and is of such a nature that the cost of maintenance is reduced to a minimum.-

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that What I claim is 1. A hydrant consisting of a cylindrical bodycast With a plurality of curved interior Walls to form a series of parallel valve-chambers which are elliptical in section with their major axes tangential to circles circumscribed about the axis of said body, the said valvechambers being open at their lower ends and being formed with interior projections to constitute elliptical valve-seats, and also having lateral discharge-ports; elliptical valves in I said chambers adapted to fit said seats; a stuffing-box plate fitting on the top of said body against the upper ends of said curved walls to close the upper ends of said valvechambers; and longitudinally -stationary threaded rods journaled in said plate and having threaded connections with said valves 2. A hydrant consisting of a cylindrical body cast with a plurality of curved interior walls to form a central chamber and a series of parallel valve-chambers Which are elliptical in section with their major axes tangential to circles circumscribed about the axis of said body, said valve-chambers being open at their lower ends and being formed with interior projections to constitute elliptical valve-seats, guides formed on said curved walls and accessible from the central chamher, a fiat stuEfing-box plate fitting the top of said body and engaging said Walls to close the upper ends of said chambers, rods journaled in said stufiing-box plate and having threaded ends extending into said chambers, an elliptical valve in each of said valve-chambers in threaded connection with one of said rods, and a main-valve nut in threaded engagement with the rod extending intothe central chamber, said nut having guides to engage the guides on said curved walls to prevent it from rotating.

3. A hydrant consisting of a cylindrical body cast with a plurality of curved interior Walls to form a series of parallel valve-chambers which are elliptical in section with their major axes tangential to circles circumscribed about the axis of said body, the said valvechambers being open at their lower ends and being provided with interior projections to constitute elliptical valve-seats, a fiat stuffing-box plate inclosing the top of the said body and fitting against the tops of the curved walls to close the upper ends of the said valvechambers, a longitudinally stationary rod threaded at its lower end and projecting into each of the said valve-chambers and having its upper end journaled in the stuffing-box plate, and a valve in each of said valve-chambers, said valve being formed with an elliptical shoe to engage the valve-seat and with an annular internally-threaded flange or boss integral therewith and in threaded engagement with its cooperating valve-rods.

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