iio segmental 'portion ofthe stemV J fis; removed. to provide' a xflat face 1 0. -Thleg end of the stem is threaded to secure alocknut 11 adjustably thereon, and flat side 10 is utilized to secure an anti-friction member 12 against independent rotation upon the stem beneath lock-nut 11. To further this purpose said member has a D shaped opening therein which is not threaded, thereby permitting axial movement thereof in setting and securing the parts together. Further fixed relation of the parts, particularly nut 11,' isl assured by a headed screw 14 which is adapted to screw into the end of stem 6, the pitch of thread of the screw being less than the external thread on the stem to assure permanent locking. It will also be noted that member 12 is rounded at its bottom edge 15, thereby reducing its bearj ing surface to a minimum where seated upon the fiat bottom 16 of recess 17 within the top portion of handle 9. This is of adof stem 6 is obtained by a rotative movement of handle 9 in either direction, and the elimination of frictionV not only makes the operation of the handle easy and aids selficlined grooves 18 and 19, within the bottom and top of handle 9 and nut 5, respectively,

and by balls 20 confined in the pockets pro duced by these oppositely related parts. Thus, when handle 9 is rotated, it will ride upwardly upon the balls, which latter in turn ride also upwardly on inclines 19. lf not checked, the balls will be carried forward into the next adjacent pocket and the valve will suddenly close itself, which obviously would be a great objection; and moreover, if the balls do not travel uniformly and jointly over like distances, there is always danger of one or more 'of them overriding into adjacent pockets to the detriment of operations. When this occurs, say if one ball only over-rides, the parts become jammed and inoperative. If force is now applied to turn, the handle the seat or balls may be crushed or the faucet otherwise imvpaired. These objectionable results are more apt to occur after wear takes place or if the parts become loose or changed from their original setting. This possible contingency is generally understood and the parts are usually constructed toy avoid troubles of this sort when the faucets are first produced, but positive means are not Y always' originally provided to prevent occurrences of this kind after the faucet has been used and worn and when the play between the parts has become excessive. Therefore, in the first instance, I have provided a fixed and positive stop sleeve 21 at the bottom of nut 5 to limit the upward movement of stem 6 by engagement with enlargement 7, and in the second instance, I have provided a disk-shaped carrier and separator 22 for balls 20 to compel a uniform travel regardless of wear. Stop sleeve 21 also serves to hold a packing gland 23 in place within nut 5 and a flange 24k on said sleeve rests against the bottom of the nut and provides a fixed seat for coil spring 25 which encircles enlargement 7 on stem 6 and bears constantly down upon head 8 to effect self-closing thereof. The degree of axial movement of stem 6 is fixed and determined 4by the amount of play between the. bottom of sleeve 21 and the shoulder formed by the difference in diameters of the stem and its enlargement 7. Sleeve 21 and enlargement- 7 are of the same diameter to hold spring 25 central and prevent tilting and buckling, particularly opposite the gap where stop engagement is obtained. vantage in eliminating friction when uplift Now referring to ball carrier and separator 22, this device is preferably made of two thin superimposed layers of light sheet metal suitably secured together and slightly lcupped in a plurality of places for the balls. yThese balls are thus spaced at equal distances radially about a central opening 26 yand are bodily removed with the carrier,

being permanentlyconfined therein for all lpractical purposes, although the balls may be removed and replaced by pressure from either sidee-there being sufficient spring to the cupped Aedges to permit this to be done. `This is of advantage in making repairs. In

general the balls and carrier are jointly removableand replaceable to facilitate assembling and prevent loss of the balls, but in operation and when in its proper place in the faucet, the disk part 22 is actually .supported by the balls and is lifted bodily to different planes as the balls ride up their vrespective inclines. Therefore this device is not strictly a carrier but more like a connecting collar for the balls, with which a 'uniform rotary travel of the balls about the stem is certain to occur when handle 9 is rotated, and if irregularities or unevenness in the opposed inclines should be niet with in any given faucet, no unequal travel of the balls will result to cause a possible bind or check between the working parts, particularly upon a return or self-closing movement of the valve. Thus, even if a perfect fitting and uniform riding of all the balls is not obtained when the parts are first assembled-due to slight imperfections or irregular shrinkage in the castings, the subsequent wear will bring about la truing up of all the parts and the balls will soon ride evenly over the inclines at equidistant radial lines from the beginning to the end of their travel. This obviously is to the benefit of the faucet after its installation.

Then/the faucet is assembled or taken apart, access to lock-nut 11 and screw 14 is n threaded flange 33 integral with handle 9 to Ithreesepara-te and separablel pleces comprislocling 'of the buttony upon" cap "27: is inde- `this form is preferred on` account of. its. sim,-YV

If exposedfhowever, theseparts are` objectionable, both' fronifthe standpoint et appearance y and for sanitary reasons."` Therefore, I provideka suitable covering for the upper end of stem, and this vcovering rotates with handlei), and isconstructed of' ing a cap 27, a screw ringy28, and an 'indeX button 29, the latter of -porcelainyusually, although not necessarily.` Cap 27 may eithery be screw7 threaded or plain, and the., first, co'nstri'ict-ion named `is shown in"liigs. 1 lto 13, Whereas the plain form 27 is vdisclosed in Fig. 14., In any event thewap lbecomes a seat or rest for index ybutton [29" Whenever a Abutton his used. If the button is dispensed with a closed screiv cover is substituted for une 28 and cap 27.' ff f In its threaded orm cap 27 yisadaptedlto; screv7 intothe top handle 9 tto encirele. andvcover `nut 11 andy screw 14, and hasay narrow slot introduce a suitable 'tool such as a screws-l driver toscreW for unsceW the samefeither from above when index buttonf29'is removed as in `Fig. 2, or'frombelovv when theindeX button is in place and the caplfremoved Yfrom handle 9, as in Figs. wand. 7.' Screw ring 28 is secured upon cap2-7` by thumb .engage-i ment with knurled bandlV midwayk aboutl the same, and has a'flaring openingvv32 conl-l forming to the tapering Walls of button 29 to lock the sameimrnovably upon (theftopp. portion of `cap 27. In Figs. 1.to l13, thispendent of handle 9, but rinFig. '14, fscrewj ring 28 has screwy engagement with va fasten button 29 upon cap 27and said capy in turn upon handle 9. l

Als. shown in Figsgll to 11, cap 27-has a plain annular band between itsf threaded ends, and screu7 ring28 has a skirting 34to snugly tit about said/bandsthe object being to make as close a joint as possible to'pref' vent fouling andfalso to make a neat appear-r ing joint. .Skirtin'g 34 in Fig. `l@ is also placed on this screvirv ring y28' for thersame reason, but in this instance said slirtingen'- circles `a flange 33 on the handle. Diiien ences in shape or height of different buttonsv 29 make it quite necessary for screw,V ring28f to have an independent play vvor adjustmentV in respectto cap 27 or handle 9, and the!" skirting allows this Without/leaving an un.- sightly gap for the accumulation of dirt.V
