SPEUM WATIGN forming part of Letters Patent No. 617,848, dated January 17, 1899. i

nieuwe ned April 5, 189e.

To ZZ whom, "6 may Gourmet:

lle itknowu that LNV-ILLIAM l?. ZELL, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Hydranis, of which the folis a specification. y,

This invention relates to certain new and useful improvements in hydrants, having for its object to inexpensive means whereby freezing of the delivery-pipes and also to prevent the accumulation of waste water around the said pipes and valve-casing; and with this object in view the inventionconsists in the novel construe-tion, combination, and arrangement of the Darts hereinafter more particularly described.

l tional viewof line 2 2 of Fig. l.

In the accompanying drawings, forming a part of this specication, and in which like letters and numerals of reference designate corresponding parts, Figure l is a vertical sec a hydrantembodying theinven tion. Fig 2 is 'an enlarged detail sectional view of the lower part of the hydrant on the Fig. 3is a'detail elevation of one section of the inclosing casing of the valve-chamber.-

Referring more particularly to the drawings, A designates the body of i the hydrant, which extends above the surface of the ground, as usualgand is provided with a discharge-nozzie l, communicating with the delivery-pipe 2, extending through the body A and below the surface of the ground. At the lower end the delivery-pipe communicates with a valvecasing B, which may be of vany suitable shape or construction, and withthe lower end ofl this casing communica-tes asuppiy-pipe Extending below the valve-casingfl a cylindrical casing Li, of suitable dimensions, having an open lower endand provided at its upper end with a perforated drip-plate 5, which plate constitutes a seat for the valve; casing. The casing or waste-water chamber iis greater in diameter than thevalve-casing,

and the perforations'in the plate 5 are formed outside the edges of the said valve-casing, so

aste be free from all obstruction. It will be obvious that the drip-plate 5 and casing 4 may bc formed in a single piece; but preferg provide simple,4 eiiicient, and to prevent theor to the flange 6 serial Nl. 676,572. [No man.)

ably the plate 'is ilormed separate from thecasing and is supported upon an annular shoulder 6 at the upper end of the said casing, as shown, the shoulder being surrounded by a vertically-extending fiange 6?. It is preferred also to form the casing i at its nlower end with au outwardlyprojectiug,iiange '.7, thereby providing an extensive bearing for the end of the casing and rendering; it less liable to settle.

lower end to thc'surlace of the ground is a frost-jacket 8, whiclrjacketis of greater diameter than the said pipe to leave a space around the same. At its lower end the jacket 8 is formed with one or more perforationsf?, Athrough which an'v imi-,er of'cnndensatinn .or

l upon the drip-plate and waste-water .chamber 4. Inclosing the valve-casing' B and likewise the' lower end of the frost-jacket 8 is a casing 9, preferably formed in two semicon'ical sections, which are bolted or otherwise secured together, and is formed a vertical collar, which rests upon the drip-plate 5 at the outer edgethereof and closely conforms to the inner face/of the flan ge 6, thereby forminga close joint, which will prevent earth from entering the interior of the casing. The casing is likewise formed at its upper edge with a collar 6', which closely hugs the exterior surface of the frostjacket and forms a broad continuous bearing therefor. f As above stated; it is .preferred to form the casing 9 in two sections, and while these may in certain instances be either bolted together' itis usually smilie-lent to from thence into the form one casing with a lip or flange 6c, which projects from the inner face thereof and is adapted thereby forming lap-joints between the sec-i tiene from e. interior ofthe said casing. By thus forming the casing it will be obvious thatposi! tiveV securing devices between the sections are not necessary, as the pressure of the earth upon the exterior to overlapthe edge o ffthe abutting section, i

. Y 95 the casing and serving to excludedirt Surrounding the delivery-pipe 2 from its moisture which collects in the jacket may flow at the lower edges of the casing vertical edge of each section of the foo thereof will tend to force` the collars into close contact with the exterior I for the reason which willl adapted to which isa valve 10,

of the frost-jacketand the nteriorsurface of the flange 6*. This casing9issucientlylarge to leave a space around the valve-casing and in addition to protecting the valve-casing from frost it serves to prevent sand or dirt from entering and obstructing the perforations of the drip-plate.

Ihile the valve-casing at the lower end of the delivery-pipe may be dispensed with and the valve be located within the lhydrant-body, it is preferred to arrange the valve as shown, presently appear. FormecLin the valve-casing is a valve-seat, supported upon the lower end of a valve-rod 12, which extends centrallyv through the delivery-pipe 2 and is surrounded at its upper end bya coilspring 13, interposed between a stationary guide 14: and a collar 15 upon the rod, the said spring 13 servingl normally to hold the valve firmly to its seat. As a convenient means of operating the valve a lever 16 is provided, which. lever is pivoted at one end within the hydrant-body and has its. rearend projecting through a slot in the said body, and intermediate its ends the lever bears upon the upper end of the valve-rod 12 in such manner that when it is depressed the valve -10 will be forced from its seat againstl the stress of the spring 13.

Obviouslyif water be left within the delivery-pipe between the valve-easingand the discharge-nozzle there is liability of its becoming frozen. In order that this may be guarded against, the delivery-pi pe is provided immediately above the valve-casing with a drip-opening 17'-, through which water in the pipe may fiow out upon the d rip-plate 5 and 'thence into the waste-water chamber l. This drip-opeuing is always open when the valve 10 is closed; but as it. is undesirable that water should escape through it when water is being withdrawn through the dischargenozzle 1 a slide-valve 1S is provided, coinprisinga cylindrical Shell the outer periphery of which i'nalies close contact with the inner' i wall ofthe delivery-pipe. This shell is conncctefl by means of radial arms `2O with a collar 2l upon the valve-rod, the said collar being fixed to the rod to move therewith. Normally the lower edge of the shell is im mediately above the opening 1T, leaving said opening unobstructed'. When, however, the valve-red isdepressed to open the valve 1U, the

.shell isalso lowered, thereby closing the said opening, lYhen the valve is again closed, the

openingis uncovered, allowing the water remaining in the delivery-pipe above the valvexeasing to flow to the waste-water chamber.

It wilhbf course be obvious that the opening l and valvel-S may be dispensed with, if desired; but it is preferred to employ them,

iliefreczing-of the delivery-pp`is precluded thereby.

Various changes in thc,construetion and arrangementxepnrts maybe made without departing from the spirit or scope of the invention, and I therefore do not wish to be limited .to the precise construction and arrangement shown, since What I claim isii. In a 1i ami, nie combinati@ with ii delivery-pilN adapted to extend below the.

surface of the ground provided with a valve and having a drip-opening upon one side of the valve, an inlet-pipe communicating with the delivery-pipe at the opposite side of the I valve, and a casing constituting a waste-water chamber arranged below and away from the inlet-pipe and communicating with the drip-opening, lwhereby the waste waterfrom the delivery-pipe is conveyed away and prevented from surrounding the delivery and inlet pipes.

2. In a hydrant the combination of a de-l livery-pipe, a valve-easing .1itt flle` lower end' of said pipe having a valve for controlling i the iow of water through the pipe, an inletpipe communicating with the valve-casing upon one side of the valve, a waste-water chamber below and separated from the valveveasing, and a jacket surrounding the valvecasing, the space upon the' opposite side of the valve from the inlet-pipe communicating with the chamber of the jacket, and said latter chamber communicating with the waste water chamber, substantially as described.

3. Ina hydrant,the combination of avalvecontrolled delivery-pipe, a frost-J'sck'et sur'-A rounding said pipe,a second jacket surrounding the first and the lower end ofthe deliverypipe and a wastewater-chamber below the second jacket communicating with the chamber of the jacket, substantially as described.
