. Be it known that I, HERBERT Ha CBAMER, ot Aspen, in.A the, county4 of Pitkin andzState of. Co brado, have invented certain new and..

lusefulA Improvemente inValves; and. I do hereby declarethe following to vbe a full, clear, andiexactfdescription o .the invention, such astwilLenable .othersskilledinthefart to.y which it to;` makeand. usey the same.. The primary o4 ofthis invention is toprovide improve means: forv removably olding a valve seat in place withine its casing; and further objects are to hold such seat by the same means that secures the partsvofl thacasing together i, in'. simplifjr landcheapen y the. valve seat to. be reversed; to protect. the contactin 4or engaging surfaces of ythe valve disk an seat from j by rust. ete.; Yand toallow the inlets allid outlets to kbe positionedl at differes. The mvention will be hereinafter fully'set forth and particularly Vpointed vout in the claims.. j I l 'In' .the accompanying drawings, Figure 1 is.

a vertical. sectional view of v a `valve embodying my-invention... Fig. 2 is a similar view at right angles. Figs. 'g'3 4. :and 5 show slight modifications. V6 is abottom plan view of the valve disk. Fig, 7 1s a section on line 7f3?, elevation.

Referringto the drawings, 1 designates a lcasing which in Figs. 1, 2 and 3 I have shown as being composed of two parts 2 and 3, each having a lateral branch/1, one servin as the inlet and the other as the outlet. 2 of the Casin is formed at its top with a large threadefh openin to accommodate a' nut 5 and packing glan 6 through which o erating stem 7 of the valve-disk 8 is passed. e sai threaded opening is of diameter Fig. 8. is, a fragmentary side 4 about corresponding to-the diameter of the chamber of casing part 2. In this latter part is formed, near the lower edge thereof, 4an inner annular shoulder '9 to accommodate valve-seat. 10. This valve seat is of circular formation and is formed with two ports '12 with which are desig'ned to coincide two corresponding portsA 13 of valve disk 8. The valve seat 10 is shown in Figs. 1 and 2 as formed with a central threaded opening, the ends of which are flared, and into which opening screws one end of a bolt 14, the other T e part the end thereof being projected through an openmodification 1n the to be turned so as to .in'casing part at the axialcenter ofthe it e,fa. nut 15 beingscrewed lon the outer., projecting end. of such boltd By thls meansK thevalve seat andthe two v 'are held in place by the same agencyto wit.:

parts of the .casing the s' le nutted bolt' engaging, the valve seatv an projected. through When Y worn it mal be readily removed-and ledor. immediate y l the sarnemanner `as before. isjof, de-

feasible to immediately file thev worn facegof It isnot necessary, however,

thevalveseat. i that in all instances the valveseatshouldbe. reversible, nor is itnecessary thatthe casing be formed in twoparts. "In-Fig. .4: I `have z shown the casing as formed-'inone part,

the valve-seat as hayingde ending angular lu s 1.6 .to. engage theheadgofanutted. bt 17,` which bolt will, asin the yformer inf stance, removably hold. 4 place. In Fig. 5 -I have-shown a further form ofA a. centrally threaded hub 18, depen Y' tromfthe underside of the valve seat, an withwhi'ch enthe valve seat-fin 5.x

gages the inner threadedend'of'aJ boltlQ'pro.-

'ected inwardly through-the o e inthe, bottom of the casing. -Intliisliitiielfnstance the valve-seat in place by though the'casing isshown'asformed'in one shownmay be employed conjunction with a two-part casing, the arts of which willv beirml held to ether hy whic retains t c val've-seat in place.

I preferably of the two parts of the valve casing with squared portions 20, such squared portions by engaging straight walls 20a vent any accidental turning of the two parts ofthe valve casing,

placethe inlet and outlet branches at different angles. While I prefer' to employ a single bolt engaging the valve seat and extending through an opening in the casing, yet it is manifest that, if desired or necessary, additional bolts may be ein loyed for engaging with the valve seat, suc bolts being-likewise extended through the casing. The valve-seat may be held as against turning by lugs 2Gb engaging some de ending art thereof, as shoiilh in Fig. 5.

l) have shown the valve-disk 8 as formed in 'its working face with countersunk circular and yet allow the parts is not reversible, but it i'sheld l the singlenutted bolt, and al.-

.part,.yet it is manifest that any ofthe meansJ the same means,

serving to pref recesses 21, the diameterb of each of which l equals that of the ports 12 in the valve seat,

' always protected oneby the other.

The advantages of my invention will be apparent. From what has been said it will be seen that by locating the securing means axially of the valve the parts of the casing may be turned so that their laterals will be presented at different anglesz that is to say, they may be located at right angles or face in opposite directions, as shown in the drawings, or at points intermediate these two positions. .It will `also be noted that the parts of the casing are held together by the same means that retains the` valve seat in place; and also that by securing the valve seat by means readily accessible 'from the outside of the casing the'valve seat may be readily removed for the pur. ose of filing, and, in some instances, reverse so as to present its unused face to the valve disk.

I claim as my invention: l

1. valve casing havin an internal annular shoulder, a removabgle valve seat located wholly within the casing resting against such shoulder and constructed so as to be capable of being reversed, and means for securing such valve seat in place comprising a bolt extended through the valve casing.

2. A valve comprising a casing formed in two arts, a valve seat designed to it in one of said parts, and a sin le agency for engaging said valve, seat an projectlng through one of said arts for holding the seat and the two parts ci) the casing together.

3. A valve comprising a casing formed in two parts, one part having an annular shoulder, a valve seat designed to Jrit against such shoulder, and a bolt engaging the valve seat and projecting through one of the parts of the casing for holding the seat and the parts of the casing together.

4. A valve com rising a casing having an internal annular shoulder, a valve seat having a threaded opening at its center extend-` 'ing' therethrough, said valve seat being reversible, and a threaded bolt engaging said valve seat and extended through the casing.l

5. A valve comprising a casing formed 1n two parts, each of the parts having interlocking squared portions, one art vhaving an inner annular shoulder, a va ve seat designed to rest against said shoulder, and means for securing said valve seat and the parts of the casing comprising abolt projecting through one ofthe parts ofthe casing.

' 6. A valve com rising a valve-seat having ports extending t erethrough and countersunk recesses in its face of a diameter'equal to said ports, and a valve-disk having'ports designed to coincide with those of the valve seat and also having countersunk recesses correslponding to those ofthe valve seat.

7. valve comprising a valve-seat having opposite] arranged ports and countersunk recesses in its face on the same circumference as the said orts and midway thereof, and a valve-disk aving ports corresponding to those of the valve seat, and on its face formed with countersunk recesses designed to coincide with the orts of the valve-seat when the valve is c osed, and with the countersunk recesses of the valve seat when the valve is opened.

In testimony whereof I have signed this speciication in the presence of two subscribingwitnesses.

. HERBERTH. CRAMER.
