Application filed January 24, 1914. Serial No. 814,170.

To all whom it may concern:

Be it known that I, EMANUEL RIoKnRs- BERG, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Self-Closing Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which,

j with anintervening D washer which form it pertains to make and use the same.

This invention relates to self closing faucets and consists in the peculiar construction of the same allowing of the convenient adjustment or regulation of the valve and its seat in relation to each other, said regulation being accomplished by means of an adjusting device located at the upper end of the valve stem which adjusting device comprises means for locking the stem in the adjusted position.

This invention further consists in the combination of valve adjusting means, and operating means with means for preventing the rotation of the valve and valve stem when it is adjusted or when it is opened or closed.

The object of this invention is to produce, first, a faucet of the type set forth which can easily and economicallybe manufactured and then, to produce a faucet in which the valve and its seat do not become worn unnecessarily by working on each other.

Another object of this invention is to produce a faucet which will preventthe usual pounding or rattling when the valve is open.

.Gther objects are apparent and will appear in the specifications and be fully set forth and claimed.

In the drawings, Figure I, is aview in central vertical section of a faucet embodying this invention, Fig. II, is a view in front elevation with a portion of the cap and body removed showing the means employed for opening and closing the valve. Fig. III, is a top plan view of the faucet. Fig. IV, illustrates in section the valve stem and parts contiguous thereto, showing the'means employed for preventing the rotation of the valve stem while at the same time allowing it free vertical movement. Fig. V, is a sectional view of the valve stem and its contiguous parts showing a modification of the means shown in Fig. IV. Fig. VI, illustrates in elevation a valve stem constructed in cross section similar to that illustrated in cross section in Fig. IV, showing the same as provided with the side splines which engage 111 slots or ways in a contiguous part or member of the faucet. Fig. VII, is a view in elevation of a valve stem made in accordance with the cross sectional view in Fig. V. showing the lower portion of the stem formed polygonal in cross section and adapted to have vertical movement in a correspondingly shaped soclret forming part of the faucet. Fig. VIII, illustrates a lower and upper nut the means for adjusting the valvestem and valve hence the tension of the compression spring and also forms themeans for locking theadjustment,the upper'nut acting as a lock nut which is forced tightly against the D shaped washer. Fig. IX, is a detailed view of the packing box bushing which is provided with the collar shown in Fig. X.

In the drawings, 1 represents the main casing of the faucet whichis provided with j the usual; spout 2 and valve seat 3..

4 represents the valve stem having valve 5 located on the lower end, said valve being of any suitable material and adapted to'seat itself on the'valve seat 3 of the faucet is held normally in said seat by means of a compression spring 6, the lower part of said spring resting against the annular shoulder enlargement? of the valve stem 4 and the upper end of said spring 6 resting against a ring 8' which surrounds the lower part of the collar 8. The collar 8 is provided on its upper. end with screw threads and forms a packing box while the lower end of said col lar'8 is provided with a depending slotted flange said slots of the flange forming ways 9, 9, which receive the splines 10, 10 of the stem 4 thus preventing the-valve stem from rotating when the parts are assembled and at the same time allowing the limiting of the upward throw of the valve stem 4 and i the valve 5.

By screw threading the upper portion of the collar 8 is fitted thus forming the stuffing box around the stem 4, and it is this bushing also which rests upon the upper edge 13 of the faucet body and is clamped thereon by means of the cap let. The upper end of the bushing 12 is provided with a suitable number of oppositely inclined ways 15 which receive and form the lower support and runs for a series of balls 16 and which in conjunction with a bushing 17 having correspondingly shaped runs on its under surface form the means for opening the valve of the faucet upon the rotation of the bushing 17. The valve stem being screwthreaded on its upper end is engaged by an adjusting nut 18 which rests upon. the upper end 19 of the bushing 17, thus adjusting of the valve in relation to seat 3 is accomplished by the turning of this nut 18, the spring 6 holding the valve 5 to the seat 3 when the faucet is in its normal position. Above the nut 18 is a D shaped washer 20 which fits over the end of the stem l, the stem at this portion being flattened .to accommodate the D washer. Above D washer 20 is a lock nut 21 which by being screwed down upon the D washer 20, locks the parts in proper adjustment. The upper end of the bushing 17 is formed polygonal and this portion fits into the handle cap 22 which has a correspondingly shaped orifice. The handle 22 is kept in place by means of the indicator nut 23 which is screw threaded to the extreme upper portion of the stem 4. lihe handle cap 22 is formed with a downwardly depending flange 24: which fits over the clamping cap 1-1 thus preventing the accumulation of foreign matter in the working parts of the faucet.

In Figs. I, IV, and VI, I have shown the valve stem as provided with two splines 10,

10 which are guided in ways 9, 9 in the contiguous part of the faucet to prevent the turning of the stem thus causing a perfect vertical movement to the stem in relation to the seat 3.

By referring to Figs. V, and VII, it will be seen that I have shown a modification of the the spline construction and in place of the splines I have illustrated the lower portion of the valve stem 4 being formed polygonal and have at the same time formed the contiguous part of the faucet so as to correspond with the stem 1 thus obtaining the same results as are obtained by the spline construction shown in the other VleVS- By referring to Fig. I, it will be seen that I have so constructed this invention that if it is desired to replace the valve 5 all that is necessary to do is to remove the cap 14:

and the whole working parts of the faucet may be placed in any radial position deired.

In setting forth this invention I have shown and described it as it appears best adapted at the present time but there are details of construction which can be easily changed without departing from this invention hence I do not wish to be limited to the exact construction as set forth.

hat I claim is:

In a self closing faucet, a valve, a valve stem, a rotatable handle, means operated by said handle to lift said valve and stem, adjusting means at the upper end of said stem for adjusting the parts, said adjusting means comprising an adjusting nut and a locking nut with a non-rotatable washer located between said nuts.
