Application filed June 26, 1913. Serial No. 776,483.

ticularly to that class of valves that move about a pivot against the end of a pipe, the

object of the present invention being to provide means whereby the valve will always accurately seat when moved about its pivot into contact with the pipe end.

The invention consists primarilyin providing the valve with a tilting disk balanced on a central projection extending upwardly from a bottom plate, said disk being adapted to move on said projection to accommodate itself to the plane of the valve seat.

' The invention further consists in certain novel features of construction and arrangement of partb which will be fully understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure ,1 representsa vertical section of a device embodying the features of the present invention. Fig. 2 represents an enlarged section of the valve itself, and the end of the pipe which it is intended to close. Fig. 3 represents a plan view of said valve, and Fig. 4. represents a plan of the blank from which the chambered portion of the valve is formed.

Similar characters designate like. parts throughout the several figures of the drawings.

In the drawings, 10 is a pipe to the end of which is threaded a casmg 11 having a chamber 12 therein. The lower end of this casing member 11 is provided with an outlet boss 13 to which is threaded a discharge pipe 14. In the end of the pipe 10 is a nipple 15 extending into the chamber 12 and having its outer periphery beveled off to form a suitable valve seat.- Extending laterally of the chamber 12 is a in or stud 16 on which is mounted the mem er 17, having a weight18 at one end and having secured to its opposite upper face a chambered member 19. This chambered member 19 is formed of a. blank such as is'shown in Fig. 4 of the drawing, consisting of a bottom plate 20 and a plurality of extensions 21' subsequently bent upwardly as at 22 and inwardly as at 23, thus forming a means for positioning the self-seating disk 24 resting upon a centralprojection 25 extending upwardly from the bottom plate 20. The disk 2ft is covered with leather or some other yielding material 26 held in position on the disk 24 by means of a ring 27, which is semicylindrical in cross section. Normally the disk 2426'27 T is. balanced on the upward extension. 25 and prevented-from displace ment'bymeansof the inward projections 23. As the member 17 moves about its pivot 16 the disk 24. is adapted to tilt upon the end of the projection 25 to accommodate itself to the plane of the seat on the end of the pipe nipple 15 so that an accurate-closing will always be assured. K

Any inequalities in the edge of the'valve seat will be cared for by the yielding covering 26 to the disk 24. The periphery of the retaining ring 27 of thedisk 24 is curved to facilitate the tilting of said disk, obviating any liability to cramp in/the tilting movement against the uprights 22. This makes a very simple and convenient form of selfadjusting valve which may be manufactured at little expense. 1

It is believed that the operation and many advantages of this invention will be fully understood from the foregoing description.

Having thus described my invention, I claim: 7

1. A device of the class described, comprising a valve seat, a closin disk to coact therewith, and a disk-retaining member formed from sheet metal having a plurality of disk retaining fingers and an embossed central pivotal point pressed up from said metal to support the disk.

2. A device of the 'class described, comprising a valve seat, a valve closing disk, a leather face therefor, a rin'gof semi-circular cross section having a thickness equal to the thickness of the disk and leather adapted to clamp the edge of said leather face to the Signed by me-at Boston, Mass.,this 12th edge of said disk, and a disk retainin memday of J une, 1913. ber formed from a single piece 0? sheet metal having radial fingers bent up to R TRIPP; loosely embrace the disk and a centrally dis- Witnesses: posed projection pressed up from the metal WALTER E. .LOMBARD,

to form a supporting point for the disk. NATHAN C. LOMBARD.
