VALVE.

Application filed May 11,

To all whom it may concern:

Be it known that I, EDWARD J. KILEY, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention relates to valves and more articularly to the disc holder of the valve, y means of which the disc proper is maintained in position.

The object of my invention is to produce a simple, eflicient and economical disc holder whereby the disc proper may be removed from time to time as its face, which comes in contact with the valve seat, may become worn.

My invention resides in the construction, 39 combination and relation of the various parts more fully described hereinafter.

In the drawings accompanying this specification- Figure 1 is a bottom plan view of the cup 85 portion of my disc holder.

Fig. 2 is a sectional view of Fig. 1 on the line 2-2. I

Fig. 3 is a top plan view of the cup portion or member.

Fi 4 is a top plan view of a washer member which I employ.

Fig. 5 is a sectional view of Fig. 4-. on

the line 5-5.

Fig. 6 is a plan view, top or bottom, of 38 the disc proper which is usually of composition of varying properties to meet require ments.

Fig. 7 is a side view of the disc shown in Fig. 6. 4o ig. 8 is a side elevation of my disc holder and disc proper in partial section.

Fig. 9 is a top view of Fig. 8. Fig. 10 is a bottom view of Fig. 8. In the improved construction embodying my invention I employ a cup member 1 which I form up out of sheet metal such as phosphor bronze, brass, steel or copper or other similar or suitable material. The process of forming up the cup member 1 is so that usually employed in similar work of stam ing, spinning, drawing, etc., and

whic operation is brought about b a variet of processes well known to t ose. skills in the art.

The finished member 1 is provided with a' 1922. Serial No. 560,055.

raised boss 2 and having an opening 3 in the face of the boss. The opening 3 s for the reception of the stem 4 of the valve. The boss-2 is so formed as to provide a shoulder 5 against which the flange 6 on the stem 4 engages. The side wall or flange 7 is provided with a plurality of slots 8 thereby cutting the side wall or flange into a plurality of segments forming a circle and each segment having a certain amount of resiliency, which would not be the case if the slots 8 werenot present. The outer edge of the side wall or flange is provided with a turned-in shoulder 9 to engage with and hold the composition disc. 10 in position- I also employ a washer member 11 which is formed up out of steel, copper, brass, etc., which is positioned within the cup member 1 as shown in Fig. 8. The washer 11 takes the downward thrust of the stem 4 when the valve is in a closed position, and as this thrust may be very severe, the member 11 is made quite heavy as compared with thecup member, and in order to reduce the thickness of the material used in the washer 11, but 'to maintain its strength I shape the member 11 as shown in Fig. 5 by producing a boss 12 thereon. This boss being hollow on the under side next to the composition disc, no strain or pressure is exertedupon the center' of the composition disc, but the pressure is transmitted to that portion of the composition disc which is directly over the valve seat and, therefore, the composition disc is not subjected. to any torsional or bending stresses, but only to direct compressive stresses.

In assembling my invention the cup member 1 is first placed upon the stem 4 and in engagement with the flange 6 on the stem. The washer 11 is then laced in position and the composition disc is then sprung into position. If the parts have been properly formed to size, the lip 9 on the various sego ments' forming the side walls of the cup member will engage and press against the edge of the composition disc, thereby holding the parts securely in position and engagement with each other through the resiliency of the segments forming the side walls of the cup.

It will be readily understood that one of the advantages of my invention is the fact that the disc 10 can at any time be readily n removed if necessary and replaced with a new composition disc. It will also be evident that various modifications of my improved disc and holder will suggest them- .selves to those skilled in the art and, therefore, I do not wish to be limited otherwise than by the following claims.

Claims 1. A disc holder for a valve disc comprising a cup shaped member, the side of the cup member formed of a plurality of segments toieldingly grip a disc and maintain it wit in the member, means on the cup member to receive the end of an operating stem and means in the cup member to receive the thrust of the stem in closing the valve.

2. A disc holder for a valve disc comprising a on shaped member the side of which is forme of .a plurality of resilient se ments and having means on the edge of said segments to maintain the disc in position within the cup member and means for attaching the cup member to an operating stem.

3. A valve comprising a cup shaped member having a segmented resilient side wall and having means on the ed e of the wall to engage and hold a disc, a isc ositioned within the cup member and hel by said wall and means, means on the cup member to receive an operating stem and secure the cup member to the stem and means to transmit the thrust of the stem to the disc.

4. A valve comprising a cup sha ed memher having a resilientside wall ormed of a plurality of segments, a disc positioned within the cup member, means on the cup member to receive an operating stem and secure the cup member to the stem and means to transmit the thrust of the stem to the disc, and means on the side wall to retain the parts together.

5. A valve comprising a cup shaped member provided with a recessed boss to receive a headed operating stem and a resilient side wall comprisin a plurality of segments, a disc posltione in the cup member to engage the seat in a valve, means inter osed between the head of the stem ahd disc to impart thrust from the stem to the disc,

meaeoe gage the seat in a valve, interposed means between the stem and disc to impart thrust from the stem to the disc, means on the interposed means projecting into the recessed boss and engaging the head of the stem for applying the thrust from the stem to the outer portion of the interposed means and means on the edge of the segments of the side wall to hold the parts in position, but

permit the disc to be removed from the cup member at will.

7. A valve comprising a cup shaped member, means on the member to receive the end of a valve stem, means on the stem to engage the means on the member to limit the relative movement of the member and stem in one direction, a disc positioned within the member to engage a valve seat, means interposed between the stem and disc to distribute the thrust of the stem over the surface of the disc and turned over means on the member to engage the edge of the disc and maintain the parts in a fixed relative position.

8. A valve comprising a cup shaped member, a disc received in said member to engage a valve seat, means formed up out of the member to receive the end of a valve stem, integrally formed means on the stem engaging the member for moving the member and disc in one direction when the stem is moved in that direction and means within the cup shaped member engaging the disc and stem to move the disc and member in the opposite direction when the stem is moved in the opposite direction and means to main- "tain the parts in an assembled relation.

in testimony whereof I afix my signature.

EDWD J. KILEY.
