SPECIFICATION forming part of Letters Patent No. 657,319, dated September 4, 190).

Application filed March 24, IQOO. Serial No. 10,091. (No model.) v

To all whom it Ina/y concern:

Be it known that I, WILLIAM H. RAWE, a citizen of the United States ot" America, re-

siding at No. 56 Central avenue, in the city.

of Pawtucket, county of Providence, and State of Rhode Island, have invented certain new.

and useful Improvements in Stop and Waste Cocks, of which the following is a specification.

My invention relates to that class ,of stop and waste cocks in which the valve opens and v closes by the reciprocating movement of they terior annular flange, said sleeve-nut having an interior enlargement provided with a centrally-serew-threaded opening, a series of longitudinal openings extending through theenlargement of said sleeve-nut and communieating with an outer inclosed chamberV thereof, an outlet-pipe communicating with `said chamber, a packing-ring interposed between the interior flange of said hub of the valvecase and the inner end of said sleeve-nut, a

reciprocating valve-rod having an exterior screw-threaded portion to engage with the screw-threaded opening of said sleeve-nut, a

valve-disk carried by said valve-rod, With a cap having a central circular aperture of a diameter to receive the annular flange of said sleeve-nut and its circumferential flange screw-threaded on the inside to engage with the screw-threaded end ofthe hub of said `valve case, as hereinafter described and claimed.

Referring to the drawings, Figure l represents a top plan elevation of the waste-cock. Fig. 2 is an enlarged central section of the same, showing the valve closed and the waste opened. Fig. 3 is a cross-sectional View taken in line x n of Fig. 2. Fig. 4 is an elevation of the sleeve-nut. Fig. 5 is a central sectional view of the same. Fig. 6 is a central section ot' the waste-cock, showing the valve open and the wasteclosed. Fig. 7 represents a central section of the waste-cock in a modified form. Fig. 8 is a front end elevation of the same. i

Like letters of reference indicate corresponding parts in the different figures of the drawings.

A designates the body orvalve-case, having a Water-passage divided by apartition b into two parts c and d, respectively. The partition b'is provided with a circular Opeliing e, forming a communication between the parts c and d of the water-passage.

Surrounding the opening e is an annular valve-seat f, against which the circular valvedisk o rests in closing the said opening c.

The valve-case A has a centrally-located hub h, tubular in form and screw-threaded upon its exterior su rface. This hub has an interior flange e', provided with a circular open- Ing cjis a packing-ring which fits the bore of theihub h and rests against the flange t' and is provided with a circular opening Z of a lesser diameter than the opening of' the said iiange. A

B is the valve-rod,having an enlarged screwthreaded section which extends outwardly from the relative position of the packingringk, the inner portion of said rod having a cylindrical enlargement m of a diameter to fit the opening of the flange e' of the hub h. This enlarged portion of the valve rod is turned down at the outer extremity to the diameter of the opening in the packing-ring and forming a shoulder n, which abuts the inner surface of the said packing-ring when the valve is open.

o is the valve-disk, secured upon the end of the valve-rod by the screw p.`

C represents a sleeve-nut of the form as shown in Figs. 4 and 5, having one end portion r mounted in the hub h and adjoining the packing-ring. This sleeve-nut has an exterior flange w. The inner end of thesleevenut is provided with an opening s, corresponding in size and location with the opening in the packing-ring. This sleeve has an inner wall t surrounding its circular ange and integral therewith, and said wall is pro- IOO - end of -thehub h` ofthe valve-case.'

vided with a p screw-threaded opening and' forms a .nut to receive the screw -thread of the valve-rod.` Thiswall isfurther provided with a series of longitudinal openings/11 extending through fromv either side thereof, said openings communicating with the cham-1 ber c, ywhich is `tapped to receive a waste-` tubew, adapted to discharge the wastewa- Vter in the placedesired to receive it. y t VD is a cap or flange-union lfor securing the sleeve-nut in any desired position upon the'v Awaste-cock, said .cap having va central circular opening y of a diameter toreceive the lexterior flange wot' the said sleeve-nuinandvits `circumferential flange screw-threadeden theinside vto engage with the screw-threaded In referring Ito' Fig. 2,' which showsl the valve closed, it will beobserved that the en'- largementof the valve-rod is constructedso. that lts outer shoulder extends inwardly'froln the face of .thepacking-ring, which allowsofl aclearance-'s'pace for the waste water to fiow through from the pipe c' andpassing through theopenings u of the sleeve-nut and into the' waste-tube w,`from whence it is deposited in a receptacle tol receive it. I use a coarse pitch of screw-thread on the valve-rod, which. when turned bythe handle d givesaquick,

reciprocating movement, whereby the shoulder n of theenlargement of said valve-rod is brought to .bear against the surface of, the packing-ring, (see Fig. 6,) and thus prevent-V mg the-force of water to escape through the.

waste-tube w.

The sleeve-nut `C extends outwardly fromV the waste-chamber@ and surrounds the valverod to receivea stufting-box s.

This arrangement of parts for a stop and f waste cock forms a construction that is Vvery simple, compact, and durable and possessing the advantage ofhaving no spring to operate and weaken through lapse of time.

drawing out together the valve-rod and sleevenuta new ring can be very readily drawn over the valve and down upon the face of the sleeve-nut, after which the said parts are inserted in the huh of the waste-cock and the sleeve-nut turned to such position that its waste-tube will discharge its water in the direction required. The flange-union is then screwed up tight and firmly securing the sleeve-nut in place.

In Figs. 7 and 8 I illustrate a modified conu struction of my invention by which the sleevenut can be made adjustable to a half-turn upon the, hub oi' the valve-case, said sleeve Should l the waste-cock require apacking-ring, by; simply unscrewing the flange-union Dl and l having a projecting ear 0"' integral upon eitherfside thereof and conforming in size 4and location with ears h"of the hub h of the valve-case, the ears h"'havingscrew-threaded openings to receive the adjusting-screws df',

4which pass through openings in the .ears of VTthe sleeve.

What I claim as my invention,and desire to secure Iby Letters Patent, is Y Y `1..;In combinationwitha valve-case of av sto and waste cockY havinUa circulariano'ed hub integral therewith `andlprovided with an exterior-screw-threaded sur'face,said h ub havfingen-'interior ange, the axis of which is in "alinement with the axis of the valve-seat, of

a' cylindrical 'sleeve-nut. C Vmounted in said `hub and having an exterior annular ange m of alesser diameter thanrthefdiaineter of the hub, said sleeve lhaving an interior wall t providedwitha centrally-screw-threaded openl .'{inga series of longitudinal openings u in said wall and communicating with au t outer 'chamber fu insaid sleeve, an outlet-pipe w commu nicatin g with said chamber, a packing- Vring lc interposed between the interior [lange of the Ihub of said valve-case and the inner face of said sleeve-nut, a valve-rod B having yan exterior-screw-threaded portion to engage with the lscrew.-l threaded opening in said sleeve-nut, said Valve-rod having a circular .enlargement m provided lwith a shoulder 'nl .adapted to bear against the face of said pack- `ing-ring when the valve is open, a valve-disk carried by said valve-rod, with a cap D having a central circular opening of a diameter to Vreceive [the exterior annular flange of said ,sleeve-nut, and its `circumferential flange screw-threaded on the inside to engage with lthe screw-threaded end of the hub of the valvecasef,as shown and described. i 2. In a stop and waste cock, a valve-cas Yhavin'ga circular flanged hub with an interior circular lange the axis of which is in alinefment with the axis of thevalve-seat, a'sleevenutinounted in the aperture vof said hub of the valve-case and provided with a waste-outlet as described, a packing-ring interposed between said sleeve-nutand lthe interior flange of said hub, and adapted, in coperation with the valve, to close the waste-outlet, with means for securing said sleeve-nut to the hub of said valve-case,as shown and described.
