Application filed. October 25, 1912. Serial No. 727,692.

To all whom t may concern.'

Be it known that I, JOHN P. FARLEY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri', have invented certain 4new and useful Improvements in `Compresof which the following is a hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure l, is a central vertical section of a compression lfaucet embodying my invention. Fig. 2, is a horizontal section through 'the handle portion of the device.

1n the said,drawing, 1 indicates the base of the faucet, the same having the customary chamber 2, and a stem 3 communicating with said chamber and depending from the base to be fitted in a. lavatory bowlor other fixture. rllhe faucet is provided with-a hollow body 41 above the chamber 2, and a discharge spout 5, and-arranged between the chamber 2 and hollow body is a partition or diaphragm 6 having a central passage 7 and an upwardly projecting wall or valve seat 8 1 marginally of y said passage. Extending upwardly from the body vertically above the base isl a hollow extension 9 which' is internally threaded at 10, and the bore of the extension is enlarged at its upper end to form a recess 11, and seated horizontally on the bottom of said recess, is a metallic washer 12, and a compressible'packing ring 13, the latter resting upon the washer and having a depend-ing boss or extension 14 and said washer and `its boss or 'extension are provided with avertical opening 15.

16 isa valve stem extending through the packing ring and provided at its lower end c with a circular recess 17 wherein lits a thin metallic washer 18 and a fiber or equivalent disk valve 19, and to secure said disk valve and washer reliably in position a screw bolt 20, extends up through them into stem 16, the said bolt having an inverted conical head 21 of such size that it materially re stricts the volume of water which can pass up` through passage 7 when the valve is only partly raised or opened, it being noted that as the valve islifted higher and higher the taperinghead ofthe bolt permits water in greater volume to pass through said passage. By this arrangement therefore, the possibility of the water being turned on suddenly with suiicient forceto cause it to of the bowl, is avoided. lt will also be noted that by having the abutting faces of the valve stern and washer 18 ground smooth, it is possible for' the stem to turn after the disk valve has been pressed against the valve seatl 8, and thus avoid undesirable wear on the said disk valve whereby its period of service is extended.

22 is an enlarged externally-threaded poror annular recess formed in the upper end of said threaded portion of the valve stem, receiving the depending boss of the packing ring, and fitting on the stem 16 at the upper side of the packing ring, is an auxiliary packing ring 24.

25 is the customary internally-threaded cap, screwed upon the upper end of extension 9, and provided with acentral opening 26 through' which stem 16 extends, said opening being of increased diameter at its lower end to snugly receive the auxiliary packing ring 24. rlihe cap is formed with an inwardly-disposed shoulder 27 which engages the upper side of the packing ring and clamps the same and washer 12, iirmly down into the recess 11.

'llhe upper extremity of the stem 16 is ver-A tically corrugated at 28, and socketed on .30 of any suitable material. The upper' end of the socket 31 of said body is corrugated at 32 to fit snugly and non-rotatably upon the corrugated upper end of the stem, the arrangement being such that the handle can be secured upon the stem to point in the same direction as the spout, without regard to how the stern is secured in the body of splash outl tion of the valve stem engaging the threads, of the extension 9, and23 a circular channel said stem is a metallic body-29 of a handle the' `faucet, that is to say, by means of the.

corrugated portions of the stem and handle, a fine adjustment of the latter may be efected and to secure the handle reliably upon the stem, a screw bolt 33 extends through the body, 29 into the upper end of the stem, as shown.

When the faucet is opened by turning the handle in the proper direction to raise the valve from its seat, the water. passes from chamber 2 through passage 7 into chamber l and thence through the s out, the volume increasing gradually as ereinbefore explained, because the downwardly-tapering head of the bolt offers a diminishing obstruction "to the passage of the water through passage 7 Because of this there is no chance for a be suddenly projected through the spout as the opening of the valve takes place.

-The cap 25 by clamping the packing ring 13 tightly in the recess 11: of the extension 9, guards against Lthe passage of water upwardly and around said ring and water is prevented from passing outwardly through the opening of the packing ring because upward movement of thel -stem results 1n clamping the boss of the packing ring tightly upon the stem. The passage of water through the cap is further f guarded against by wedged in the lower end of the opening 26 of the cap around thestem and upon the packing ring 13.

As herein before referred to, the 'stem has -a swivel action on washer-18 to reduce wear on the disk valve and the swivel action may also occur in the initial turning of the handle toopen the valve, there is more friction engendered by the engagement of the disk valve with the valve seat 8 and between the disk valve and the washer 18, than there is between the latter large volume of water to' the use of the 'packing ring 24:

and the bottom of the valve stem. The advantage of givingthe handle a fine adjustment on thestem is mainly one of appearance', that is to say it is desirable especially where there are two similar faucets attached to the same fixture, that the handle of each shall project in the same direction as the spout when the faucets are closed.

From the above 4description it will be aparent that I have produced a compression aucet embodying the features of advantage enumerated `as desirable', and while I have`illustrated and described the preferred embodiment 'of the invention I 'reserve the right to make all changes falling within the spirit and scope of the appended claim.

A faucet. -havingban internally and externally threaded tu ular extension provided with an interior step portion adjacent its outer ed e,a valve stem having an enlarged portion t readed through said extension, said enlarged portion having an annular recess opening in the' direction of the axis of the stem, a cap engaging the external threads of* said extension and fitting around the stem and forming with said stem anl annular recess wedge-shaped in cross section, a packing ring fitting in the first-named annular recess and having a shoulder engaged by said cap and1 seated in said step portion of the extension, and an auxiliary packing ring abutting against said first ring and adapted, as said cap is screwed implace, to

be wedged by said iirstring into the recess in said cap.

In testlmony whereof I aiiix my signav ture, in the presence oftwo witnesses. it being obvious that JOHN P. FARLEY.
