Application filed December 24, 19724. ySerial No. 757,838.

To all whom t may concer/rt.'

Beit known that l, VViLuAM F. RYAN, a citizen of the United States, residing at Florence, in the county of Hampshire and State of Massachusetts, have invented certain new and useful improvements in Stop Cocks, of which the following is a speciiication, reference being had to the Y.accompanyng drawings.

This invention relates yto improvements in stop cocls and more particularly to la stop cocl, the plug of which is so constructed as to veliminate excessive wear.

Anirnportant objectof the invention is to provide a stop cock, a portion'of theplug of vwhichiremains stationary and a second portion 'of which rotates, one of said por-- tions lbeing provided with a seat which is removable -andirenewable so that-,the life of thecock may be extended.

A further object o-f the invention is to produce a. device offthis character in ywhich the fplug is so constructed that turning of the sameis rendered a Av-.eryieasy roperation ias compared with the ordinary ftype of stop cock ,where the plu-g tit-s 'tightly against the walls of `the chamber.

These and other objects `l". attainby the construction vshown in the accompanying drawings, wherein for-the purpose ofillustration is shown apreferred embodiment of my invention and wherein Figure 1 is a perspective view of a sto-p cock 4constructed in accordance-with my 1nvention, thefcap of the valve body'being removed to show the v`limit mechanism employed;

v,Figure 2 is a vertical sectional view through the cock;

Figure 3 is a sectional view taken through the cock at the channel 28;

,Figure 4de a perspective view Aof the upper or body section of the rotating part;

Figure 5 is a perspective view of the seatingsection of the rotating part;

Figure 6 is a perspective view of the stationary part; and

yFigure 7 is-:a lcombined perspective View showing theV arrangement of the seating sec- .tion andstationary part where a plurality vof outlets are desired. v

Referring nowimore particularly to the dra-wings, 'the numeral 10 l.generally indicates a body of a stop cock having `a vertical f tapered bore 11 terminating at its lower end in a threaded bore 12 and having an inlet 13, and an outlet 14 communicating with the tapered portion of thebore adjacent thel'owerend thereof. The upperwend of the exterior of the body is threaded, asatl, forthe reception of aicap 16, this threaded portion having formed Vtherein a notch 17 extending circumferentially Ythrough a distance Vequal to that Vthroughy which thevalve plug,her e i nafter referred to,riota`tes. V'The cap 16 has a central opening 18. i

VThe valve plug is formed in two sections 19 and 2 0, the section 1 9"be ing `hereinafter referred to as the `stationary"sectionwhile the Vsection 2O will"be'refe'rred to as the f rotatable section. The stationary vsection has atits lower end a threaded portion, `'the Clllelldspf which engage the threaded portion 1 2 of Ithe bore vof 'the Ivalve `bodywand by Vthis,1ncans is heldin stationary posi-` tion. The stationaryV section has inletand Aoutlet ports 21 and 22 aligning with the ports lofthe inlet 13 ,and outlet l14t a'ndj'has vertical 'bores 23., 24,*'communic'ating with the ports 21,22 and opening through the upper end of thestationary section. This stationary section is lfurther provided fcentrally withv a socket25, the purpose of which vvill`-presei1tly appear. 'The rotatable section of vthe plugicomprises two sections 26 and 27, the section 26 forming the blo'dyot therotatableportion ofthe plug while the section 27 forms the yseating section thereof. The body section isprovi'de'd'in its bottom with an Aannular groove 28A and has yaxially thereof a threadedaperture-29. Through the side wall of the section 26.i s formed ,a Aport? ,0 connecting the youter surface of this side wall with the ygroove 28, the outer edges'of the side wall having downwardly extending portions or lugs 31 entering ,notches 32 formed in theseating section 27,

preventing rotation with relation to the section l26 .of the rotatable section of theplug.

This seating section is held in position bylva retaining element- 33 extending therethrougl'i and engaging in the threaded bore 29 of the section 26. "The head of this retaining element, indicated at 33, is received witliinithe socket 25 `of the stationary section of the plug. The seating sect-ion may be formed of liber, `rubber, soft metal or any suitable `materlal andinayrbe replaced as 1t wears.

The rotatablesection 20 of the: plug is `l provided. with a stem.

All

In operation, the cover of the cock is a means for forcing the lower surface of the seating section into engagement with the upper surface of the stationary section'19 so as to provide a water tight connection therebetween. rIhe cock plug may be Inade sufficiently loosely fitting that there is littleor no friction between the side wall of the rotating section and the bore 1 1 and "accordingly this body will be relatively easy to turn when the ports 27a of the section 27 are in alignment with the ports 23, 24 of the stationary section 19. The fluid is led intothe groove 28 and passes from this groove through the port 24 to the outlet. The body of the valve is preferably provided with a drain outlet port 35 with which the port 30 aligns when the ports v27at are outY of register with the ports 23, 24 so that this channel may be properly drained at all times.

It will be obvious that the construction hereinbefore set forth may be employed for multiple distribution valves such as are employed in water works or the like by simply providing a plurality of outlet ports $4 1n the lower section 19 as suggested in Figure 7. i It will also be obvious that while in the present instance, the section 19 is shown as formed separately from the valve bottom and while this is the preferable construction this may also be modified and this section maybe produced integrally with the valve bod Clertain Y other changes and modification being possible without in any manner departing from the spirit of my invention, I accordingly do not limit myself to such specific structure except as hereinafter claimed.
