To all whom z'may concern:

Be it known that I, RICHARD J. HoLznR, citizen of the United States, residing at White Plains in the county of Westchester and State of liew York, have invented certain new and useful Improvements in Double-Seat Faucets, of which the following is a specification.

My invention relates-to new and useful 1e improvements in valves and valve seats, such as are provided'for sink faucets, basin cocks, bath cocks, compound stop cocks, ball cocks, and the like.

The principal object of my invention is to provide in a faucet or cock a double-headed valve and a double valve seat,'arranging the two valve heads and their respective seats in such manner that only one valve head is ordinarily in use, while the other valve head is adapted to be brought into operation when the valve seat of the primary valve head has become worn down to such an extent that leakage occurs.

Another object of my invention is to provide for the primary valve head an adjustable valve seat which may be vertically adjusted to compensate for considerable wear I of both its seating surface and of the primary valve head. f sol A further and more general object of my invention is to construct the faucet valve and valve seats with such regard to proportion, number and arrangement of parts that they ,embody the desired features of sim- 85 plicity, durability, and eiiiciency, and may be cheaply manufactured.

The above and other incidental objects of a similar nature, which will-be hereinafter more specifically treated, are accomplished by such means as are illustrated in the accompanying drawing, described in the following specification, and then more part1cularly pointed out in the claims which are appended hereto andform a part of this application.

Referring now to the drawings, wherein there has been illustrated the preferred embodiment of'thi's invention as it is reduced to practice, and throughout the several vviews of which similar reference numerals designate4 corresponding parts, Figure 1 is a longitudinal section taken medially through the preferred form of faucet embodying my double valve; Fig. 2is a section on the line t5 2--2 of Fig. 1; and Fig. 3 is a detail perspective view of the compound valve head.

member 13 is-of considerably In the embodiment'of my invention shown in the accompanying drawing, the faucet consists in the body portion A having a removable bonnet B, an integrally formed inlet tube C, and an outlet nozzle or spout D. The body ortion A of the valve is, of course, formed withfa valve chamber E which is cut-ofi' from the inlet `passage b an integral web 10. The web 10 1s formecfTwith a passage or opening 11 through which the water may pass from the inlet tube into the valve chamber E, and thence through the outlet nozzle D.

Two concentrically arranged, spaced, vertically extending annular flanges, indicated at l2 and 13, surround the opening 10. The greater height than the flange 12, so that the secondary valve head [may be seated separately from the primary valve head -and at a higher point, as will be hereinafter more fully eX- plained. The iiange 12 is externally screwthreaded to receive a removable valve Seat 14 which, as shown .in Fig. 2 particularly, may be vertically adjusted to dispose its upper edge above the upper edge of the iiange 12 to compensate for wear either of the primary valve seat or of the head, indicated at 15. It will be obvious that the upper edge of the removable valve seat 14: forms the surface with which the lower face of the primary valve head 15 may be-engaged when it is desired to seal the passage etween the inlet C and outlet D.

The valve consists essentially in a stem 16 which is threaded for adjustment within the interiorly disposed internally screw-threaded neck 17 formed integrally with the bon'- vnet B. On the lower terminal of the stem 16 are formed the primary valve head l5 and secondary valve head 18. The primary valve head is of less diameter than the seeondary valve head, and is arranged in parallel spaced `relationl thereto, as shown particularly in Fig. 2. It is 'apparent that the 'member 15 is of considerable less diameter than the annular flan le 13 so that it may be arranged interiorly't ereof for engagement with the primary valveseat 14. The outer ,edge of the upper portion of the member 13 is provided with. a peripheral groove which receives a sealing gasket 19.v

It will now be apparent that in ordinary use the primary valvel head 15 will, by engagement with the primary valve seat 14,

. seal the passage 10 between the inlet C and primary valve f the outlet D. Should the primary valve seat and valve head become worn, however, to such an extent that leakage occurs, the user of the faucet may, without the employment of any tools, quickly repair the faucet by merely threading the valve seat 14 to its lowermostjpoint on the flange 12. When the primary valve seat has been thus disposed, thesecondary valve head 18 may be engaged with the sealing gasket 19 and upper edge of the secondary valve seat or flange 13, thus effectively cutting off communication between the inlet and outlet of the faucet. I t need hardly be explained that, when it is desiredwto adjust the valve seat 14, it is only necessary to remove the bonnet B and with it the valve stem 16.

Upon inspection of Fig. 2 particularly of the drawings, it willl be noted that my faucet valve is so constructed that the primary valve head may alone be seated and the secondary valve head may, at the same time, be arranged in open position. Also, the primary valve seat 14 may be threaded down to its lowest point on the flange 12, so that the-primary valve head 15 will be unseated while the secondary valve head 18 will be seated on the secondary valve seat. The primary and secondary valve heads are also adapted to be simultaneously seated, this result being accomplished by properly adjusting the primary valve seat 14 upon the flange 12.

In reduction to practice, it has been found that the form of this invention illustrated in the drawing, and referred to in the above description as the preferred embodiment, is the most efficient and practical;-

yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in details of. construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of this invention, as defined in the appended claims.

Having thus described the invention, what is claimed as new is 1. In a valve of the character described, the combination with a pair of concentrically arranged annular valve seats, of a valve stem, and a pair of fixed valve heads carriedthereby, one of said valve seats being adjustable with respect to the other whereby the valve heads may be selectively seated.
