To all whom ifmay concern:

more expensive than others now in use,

Be it known that we, Hnxnr ML'ELun: which is easily handled and repaired, and is and AxToN U. SClllfl-IRMAXN, citizens of the United States. residing at Decatur, in the county of Macon and State of Illinois, have invented new and u eful Improvements in Self-(l ming Basintocks, of which the following a eipeeitichtion.

Our invention relates to Self-closing faucets. and has to do particularly with the index member of these fau ets. I

.\s is well known the index of faucets which tells the character of the fluid supplied by the faucet isotten located in line with or attached to the valve fstem of the faucet. The index. member of the faucet with which our invention has part cularly to do is 10 located. being associated with an abutment mountd on the valve stem. This abutment is as ociated with an operating member which encircles the valve stem and bears against the abutment when turned to lift the valve stem and open the valve. l usually the operating member by bearing upon the abutment tends to turn the. valve stem angularly so that unless the stem is secured against rotation in some manner, it is liable to become angular-iv displaced. The index member on the. abutment is therefore. liable to be thrown out of its preferred linear position. Likewise in the assembling of the cock when the stem is placed in the casing in many YillYtrl it is diilicult to so place the stem and associated parts that the index member can be placed in the desired position. it is found further that when the parts are constructed and adjusted to overcome in some measure the .litiiculties named. the. abutment on the stem which eooperates with the operating member is subject. to wear, and thatit lost motion is not. present between the. operating member and abutment at the beginning, it soon appears after the cock has been in use. Owing to this fact the abutment cannot be made to fit flush upon the operating member at all times without undue con'iplication of the cock. Dirt, dust and soap very soon collect in the space between the abutment and opcrating member and render the fixture very unsanitary.

It is the object of our invention to overcome the above named diiiiculties and to produce a self-closing cock which is not etlicient and durable.

\Vc showone embodiment of our invention in the accompanying drawings, in whieh Figure- 1 is a central vertical sectionof the cock of this embodiment taken along the plane which passes centrally through the discharge. spout; Fig. 2 is a top plan view of this cock; Fig. 3 is a side elevation of the stem with the disk spring and collar attached, the collar being shown in section on the stem: Fig. 4 is an elevation of one of the parts 2 ssociated with the stem. Fig. 5 is a bottom plan view of the same, and Fig. 6 is a sectional elevation of the operating member and the cooperating abutment which is fixed to the stem showing the parts ready for assembly,

10 is the main casing of the cock, 11 is the valve seat, 12 is the valve disk, and 13 is the stem to which the disk is attached. Mounted on the stem above the valve disk in serial order are a spring 1- a collar 15, a clamping member 16 having cam shaped surfaces 17 (see Figs. 1 and 3), a set of rollers 18 which bear 1:11 the surfaces 17, an operating member 1.) provided with cam surfaces 20 which cooperate with the surfaces 17, and the abutment 21 associated with the operating member 19. All of these elements, except the collar 15 and the abutment 21, are ioosely mounted on the stem. In other words. excepting the collar 15 and the abutment 21, the remaining elements simply surround the stem.

The collar member 15 is shown in section in Fig. 3, in elevation in Fig. 4, and in bot.- tom plan in Fig. 5. This member is splincd on the valve stem by a. pin 22 which passes through the stem and engages the collar in slot 23 cut transversely of the collar from its under side. The depth of this slot is such as to admit. the vertical movement 01' the valve stem through a certain range. In the. bottom of this collar is formed a socket 2t which receives the end of the spring 14. The top of the collar is provided with a flange 25 which bears on a seat 26 formed for it on top of the. casing 10, and against which it. is clamped by means of the clamping member 16. The clamping member 16 ed engaging surface 27 which engages directly in frictional contact the extended top surface of the collar 15. Itis to be oh-- served that the extended engaging surfaces of the gollar 15 and the clamping member 16 respectively. are of much greater area than the small engaging surfaces of the valve seat and valve disk respectively. A rubber or other packing 29 is provided just above the collar 15 and within a recess in the clamping member 16.

Above operating member 19, the abutment :21 is provided with an engaging SUP face 30. Preferably this' engaging surface is formed on an annular ring of antifrictional metal seated in a socket on the underneath side ofthe abutment. In order to compensate for wear this engaging surface instead of bearing directly upon the top of the operating member 19 is made to bear upon an annular upward projection or ilange 33. Due both to lost motion incident to wear and to need for adjustment of the abutment 21 to the desired position there needs be a space 34 between the abutment 2t and operating member 19. This space soon becomes filled with dirt and soapy materials if it is left opened. '0 provide an annular band or ring 35 seated in a socket 3:? on the underside of the abutment 21 near its outer edge and bearing loosely on the top of the operating member 19, to keep this space 34 closed. We form the socket 35 of a depth sutlicicnt to allow for the adjustment of the index member and the abutment, without clamping the space closing member 35 tightly.

With a cock constructed in the manner described the index member is readily adjusted to any position desired with ease. The adjustment is preferably made. in the assembly of the valve, though it can be done. by a plumber with equal-facility when the lixture is installed. The procedure is as follows: All of the parts of the valve may be removed from the casing by removing first the abutment 2!, which it is to he noted is held in position by a screw 18 entering one of the slots 18 in the upper end of the wtem. and then the clamping member 16.

' All of the parts of the valve associated with spr ng ll causes a relatively great frictional c mta t, greater than the frictional contact of the disk 11 with its seat. The result is her 19.

.that the valve tem through the pin 22 and being screwed down, until the llange 25 of the cellar strikes the seat 26 on top of the casing and rotary motion of the clamping member is stopped. Thcn the rollers 18 and operating member 19 are placed in position on the stem, next the ring'ilfi is placed over the stem 13 resting upon the operating mem- After this the abutment 21 is screwed on the stem so that there is a little lost motion between abutment 21. and operating member 19. Then the abutment 31 is locked to the stem with set screw 18, its point entering one of the slots 18". Assume that the index member is then in the 15 position shown by dotted lines in Fig. 2. This position isohserved by the operator. and noted by him as being 45 from the position at right angles to the spout 10 of the co k. If it is'desired that the index he fixed in the position at'right. angles to the that it be turned counter-chickwise through an'angle of 45". To do this the operator simply unscrews the clamping -memher 1G a few revolutions, just far enough to loosen up the parts and relieve in some measure the upward pressure of the spring 14 through the collar 15 on the clamping mcmher. The clamping member is then held by hand and in fixed position with respect tothe casing ll), illlt; the abutment and stem are turned counter-clmkwise through 45' by hand or by using a wrench on the abutment. Holding the abutment in its adjusted position with respect to the clamping member, the clamping member is then promptly 5 screwed hack into place. and until it clamps the flange 25 to its seat .36 on the casin On account of the extended engaging surfaces and frictional contact of the. collar 15 and clamping member l6 thcl'c is no slip 'iage between them, and the valve stem. and hence the abutment 21 and index member is maintained in the same angular relation with respc t to the clamping member it; to which it is adjusted, and the index'mcmber is altcr this adjustment in the right position when the clamping member is screwed up lirmly. The abutment Ql need n t be held by hand unless it is found that the stem turns within the clamping nu-mhcr. Likewiseadjustment of the index member may be made to any other position, and when so adjusted is held rigidly in position by virtue of the lirm engagement of the llange. 25 of the. collar 15 with its seat. 96.

By virlmof the proiisiou r a plurality f slo s i at the upper cnd of the valve stem the abutment may be locked in any ne of i=\ll'ill angular positions with re pe t to the stem b the Hl screw l This mak it possible to minimize the angular adjustment of the index member and stem with respect to the spout, as the abutment can then he set with the locking screw 18 in the slot 18" which places the index in the position nearest to that desired. and which at same time positions the abutment c.. enough to the operating member 15) to prevent undue lost motion.

The operating member, the space closing member and the abutment are assembled on the stem in the order shown in Fig. and in assembled relation as shown in Fig. 1. As thesocliet' 35 for the space closing member 35 is of greater depth than will allow the member 35' th be clamped tightly between the operating member 19 nd th abutment it. the engaging surface So of the abutment is engaged by the operating menn her when the valve is operated and all wear is taken by the proper surfaces. 'ithin the ordinary limits of wear upon the surface 30 of the abutment. and adjustment of the index member. the space l sing memberlifi remains loose in its socket. and bearing upon the upper surface of the operatim member. effectually excludes dirt and tilth from the space between the abutment and operating member.
