VALVE.

Specification of Letters Patent.

' Patented'Aug. 7, 1906.

Application filed July 2,1904. Serial No. 215.172.

To all whom, it may concern: Be it known that I, WILLIAM PAYSON FIREY, a citizen of the United States, residing at Roanoke, State of Virginia, have invented a new and useful Improvement in galves, of which the following is a specifica- 1011. My invention consists of means for carry- 1ng out the above object; and it further consists in the use of novel materials and construction of parts having the general mode of operation as hereinafter more generally set forth in the accompanying specification and drawings, in whioh' Figure 1 is a longitudinal view of my imroved valve, valve-case, and mechanism. ig. 2 is a sectional view on the dotted line Fig. 3 is a detailed view of the several parts constituting the valve-seat container;

the non-metallic hard valve-seat, the nonmetallic hard valve-face piece, the carrier for valve-face piece, and the tension-spring. Fig. 4 is a detailed view of a valve-seat.

Similar numerals refer to similar parts throughout the several drawings.

Referring to the drawings, 1 is a metallic cup or container designed to hold and strengthenthe non-metallic hard piece 2. 1 has a port 15 as shown, corresponding to the port 15, in piece 2.- The cup 1 may be secured to the piece 9 or to the valve-body when -9 is not used by solder 'or any suitable means. It may also be discarded in certain modifications of the invention.

2 is a block of non-metallic hard substance, such as porcelain, stone, glass, hard rubber, or similar substance. It has the port through it and may have the extended bearing-surface, as shown. The object of the extended bearing-surface is to prevent any abrasive material coming into contact with the valve -face, thereby preventing wear, and -also to keep the valve in line'w-ith the valveseat.

3 is a block of non-metallic hard substance, similar to 2. Its general shape is not con- I fined to any particular design, except that it has a plain bearing-surface against the valves'eat. It may be secured to its carrier by cement or any suitable means. The piece 4 is a metallic carrier for the valve-face piece 3 and has a recess into which the iece 3 is held. A valve-stem of any suita le kind may be secured to the piece 4.. It is deemed advantageous that the piece 3 a permanent coning the port 15.

- 6 is a coiled spring through which liquid may pass and by compression serves to keep the valve faceand seat in constant contact and tension.

7 is an annular nut having the port 15. Its outer surface is threaded to engage threads in the valve-case. The nut serves to adjust and maintain tension in the spring 6.

8 is a dome inclosing the valve parts, as shown.

9 is a circular barrel having its outer surface threadedforengaging the valve-case 10 and dome 8. It has an aperture for containing the

pieces

1, 2, 3, 4, and 5 or piece Fig. 4 instead of 1 and 2- in certain modifications of the valve. v v

10 represents a valve-case having the straightway 15, the threaded circular section 16, the recess 13, and the extended threaded section 17. The case-is not limited'to any particular design.

In Fig. 4 is represented a modification of the part 2. in which 2 isshown as a block of metal 11, having a face 12 of vitreousenamel. This same modification applies equally well to the valve-face 3 and holder 4. The advantage of this form of construction is principally in allowing thinner pieces and a somewhat cheaper construction. I

As ordinarily constructed the non-metallic hard blocks would be a certain variety of porcelain. In all cases the valve face and seat are brought to a perfect surface. and are parallel to each other.

Having'thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A tension apparatus for a sliding valvegate, consisting o a plate of metal, in contact with said gate; a waterway throu h said plate a coiled s ring in contaotwith sai plate; a tension-nut having a port through same, said nut being in contact with said coiled spring, and engaging the valve-case substantially as shown.

2. A valve comprising. a casing having a bore and a recess intersecting said bore, a

port 15 through the barrel in said recess and formed with a transverse opening to aline with the bore insaid casing, and a longitudinally-extending recess or opening intersecting-said transverse opening, a valve-seat in the recess in said barrel, and a sliding valve in said recess to coact with said valve-seat.

3. A valve comprising a casing having a bore and a recess intersecting said bore, a

- IO barrel in said recess and formed with a trans verse opening to aline with the bore in said casing, and a longitudinally-extending recess or opening intersecting said transverse opening, a removable valve-seat in said longitudi r 5 nally-extending recess, a sliding gate-valve in said recessto coact with said valve-seat, means for operating said gatewalve, and a spring for forcing said valve against its seat.

\ 4. A valve comprising a casing having a bore and a recess intersecting said bore, said recess being screw-threaded, a barrelscrewed into said recess and havin a transverse opening to aline with the bore in said casing and a longitudinally-extending recess or opening 2 5 intersectin said transverse opening, an apertured va ve-seat removabl mounted in said longitudinal recess, a sli ing gate-valve in said recess to coact with said valve-seat, a

spring for holding said valve upon its seat,

o means for operating said valve and a dome or cap upon the projecting threaded end of said barrel.

5. Av valve comprising a casing having abore and a recess intersecting said bore, said 3 5 recess being screwthreaded, a barrel screwed into said recess and having a transverse opening toaline with the bore in said casingf'and a longitudinally-extending recess or opening -intersecting said transverse opening, an ap 4o ertured metallic valve-seat carrier in said 1011- gitudinal recess, an apertured valve-seat of a non-metallic hard substance in said carrier, a metallic carrier for a sliding gate-valve in said recess, a valve of a non-metallic hard substance seated in said carrier and coacting with said valve-seat, a spring-plate in said recess for holding said valve against its valveseat, means for operating said valve and a dome or cap upon the threaded outer end of said barrel.

6. A valve comprising a casing having a bore and a recess intersecting said bore, said recess being screw-threaded, a barrel screwed into said recess and having a transverse openmg to aline with the bore in said'casmg and a longitudinally-extending recess 0r opening intersecting said transverse opening, an apertured metallic valve-seat carrier 1n said longitudinal recess, an apertured valve-seat of a nonmetallic hard substance in said carrier, a

metallic carrier for a sliding gate-valve in sald recess, a valve of a non-metallic hard substance seated in said carrier and coacting with said valve-seat, a spring for forcing said valve upon its seat, an annular nut in the bore of said casing for varying the tension of said spring, means for operating said valve and a dome or cap upon the outer threaded end of said barrel.

7. A sliding gatevalve comprising a casing having a longitudinal bore therein and a transverse recess mtersect ng said bore, a

-valveseat in said recess. a valve proper slidable in said recess and coacting with said valve-seat, and an apertured spring-metal plate in said recess for'forcing said valve upon its seat.
