IMPROVEMENT IN FAUCETS.

The Schedule referred to in these Letters Patent and making of the same.

I, J AMES POWELL, of Cincinnati, HamiZton county, Ohio, have invented a new and useful Improvement in Valve-Cocks, of which the following isa spccilication.

-Nature and Objects of the Invention.

My said invention relates to the class known as valve-cocks; and consists in a peculiar combination of a guarded elastic valve-disk, a yielding-plate, and a valve-head, of metal or other hard material,

The object of my improvement is to produce an elastic valve-seat (or a plug) for cocks, in which compensation is provided-for wear either of the. seat or of the valve-plug, whileat the same time the India rubber General Description with Reference to the Drawing.

The accompanying drawing is a vertical axial section of a valve Bibb cock embracing my improvements, some of the parts being shown in elevation.

The operating-stem C 0, cap D, elastic packing-G Q R, cam F, socket E, spur K, and head I J J of the valve-stem may be similar in construction and operation to the corresponding parts described in the reissue of my patent of March 22, 1859.

S is an annular elastic Ive-disk, composed wholly or partly of vulcanized rub er or analogous material.

.Fltted in a socket between the concentric rims M m in the body or in the shank of the cock L, as shown, is a metallic-plug valve, with a threaded aperture, 1', adapted to fit a male-thread on the rear end of the yalrc-stcni 1L t' is a slot in the back of the plug, by means of which it can be adjusted and fixed to any part of the stem with a common screw-driver; or the head of the plug may have a square or other non-circular end, for use with a common wrench.

P is a flexible plate of metal interposed between the valve and its seat, and having an aperture.

0 is a collar, which slightly overlaps the edge of the plate P.

This collar is adapted to slile upon the outside of the rim M, and is confined by an internal shoulder, t, in the shank of the cock, in connection with which it also acts as a friction-washer.

The valve-head L has an annular enlargement, n,

which in the act of closing bears against the outer edge of tho yielding plate P, and acts a a compressor against the clastic disk S.

Operation.

The valve being advanced by rotating its operatingstcm C 0, its salient or conical portion is forced into the aperture in the valve-seat at the same time that the shoulder n engages with the yiclding-piatc I, and thereby compresses the rubber disk, which, being confined from lateral displacement by the rim M and flanged collar (J, and by the inner rim 'm and valvehcad L, is prevented from ci'icroaching upon the passage-way, and is forced against the valve. so as to form a perfectly fluid-tight joint without exposurein any part to the action of said fluid.

The cylindrical flange of the collar 0 maybe slightly elongated so as to take the place of thcoutcr rim M, and the annular plate I may be in one piece with the said collar, its aperture being-of such size as to afford a bearing for the shoulder a of the valvcdiead L, so as to insure the equable and uniform compression of the rubber disk and the perfect exclusion of the fluid therefrom in the act of closure. 7

It is evident that this invention is equally applicable to every variety of faucet, such as stop-cocks, Bibh cocks, globe-valves, and steam and watcncocks of every description, and also that the valve may be adapted to close either with or against the pressure or flow of the current.

I. do not propose to confin'c myself to the precise arrangement-s above selected so long as I attain the same result by means substantially equivalent for example, the seat of the cock may be of hard material and of conical or conoidal shape, as in the draw ing, while the elasticity sought for can be wholly in the valve-head L by placing the yielding or sliding plate I on the valve-stem H, so that its outer rim may engage with the conical walls of the passageway, so as to confine the rubber disk bet-ween said plate and the false head L, the complete protection of the elastic disk and its compression gainst the sides of the passage in the act of closing being precisely the same in cither case.

It is obvious, also, that the operating-stem C c and valve-stern H may be displaced by the ordinary rotating screw-spindle, as in the common compression-cock, and the projecting enlargement or shoulder a of the valve-head L, and the outer edge of the plate 1- with which it engages, may, if preferred, be cone-shaped on their bearing surfaces.

The following are among description of cocks:

the advantages of this The construction is simple, economical, and exempt from liability to derangement. I

The parts can be separated with great facility for ins tion, cleansing, or repair. he valve-seat or valve is efl'ectually preserved from contact with the fluid while the cock is closed, and as much as possible fromattrition'against any of the moving parts when open or in action; and the elastic disk, whether" in the seat or. valve proper, is readily replaced when worn, vulcanized rubber'in-the sheet be lug an article of general merchandise.

The valve is readily adjustable upon. its stem to expense in repair, such plugs being cast of metal or other hard material, and an elastic cushion behind or in rear of one or more of the bearing surfaces, so as to insure compensation for wear either to 1 the metal plates or to the rubber.

compensate for the general wear of its parts, and this 1 without any perforation through it to cause leakage.

Claims.

I claim as new and of my invention- 1. The elastic annular valve-disk or seat '8 and yielding plate I, in combination with the valve-head L, of hard material, substantially as set forth.

2. The sliding collar 0, in combination with the elastic valve-disk or seat 8 and valve-head L, as and for the purposes set forth.

In testimony of which invention I hereunto set my v JAMES, POWELL.
