LAVATORY FIXTURE. I APPLICATION FILED SEPT-19,1114.

Patented Aug. 6, 1918.

I VZ/M5 includes the usual body or casing 1 having eoperationwith the erown/liandle'as herelos'etlie tubular portion of theb'earing head a ycitizen of the .United States, residing atr 'Be it knownthat I, EARL Chicago, Cook county, Illinois, have invent- 4 ed certain new and useful Improvements inA Lavatory-Fixtures, of which the 'following is a specification.

My invention relates to a lavatoryffixture and the object thereof is to improve the construction and operation of suclrxture, particularly those of the type in which the valve is normally held closed-by spring pressure and opened againstsucli pressure. My invention consists more, particularly in the,

provision of vnovel and simple means for locking the `valve 'steiii'and adjusting nut in" adjusted position and also in the provision of novel and simple cam means for operating the valve by means of the usual crown handle and for preventing the sticking of the handle which frequently occurs in fixtures o'frthis type.` rThe various features of 1 advantage and utility in my new constructionvoflavatory fixture will be apparent from the de scription hereinafter given. I

The'headis provided Vwith an .upwardly extending shell portionhaving three inwardly 'directed ribs" 6 forming stops in inafter described."v Y* y n The crown handle 7'co`nsists of' acentral ylindrical lportion and'fan outer marginal 4shell portion7b adapted to overhang and in- MVATORY-FIXTURE Specicatilon of Letters Patent.

the action ofthe ballsin riding upwardly upon the inclined cam surfaces of theI grooves 6a. Inasmuch as the valvestem is operatively connected f* with the crown haii dlev in the manner hereinafter explained, the valve will be opened. n

TheY crown 'handle can be operated in Veither direction, that isb-y turning to the right or tothe left, but it is desirable that meansbe provided for limiting the niovefn ment of such rhandle in either direction and one featuieof. my invention relates to such means'. yThe stops 6b,`lierein beforereferred to,` are three in number corresponding to theA Y number of cam groovesandrballs employed and any two o f them are adapted'to coper ate with the single stop 7d formedon kthe exteriorA of the Vcylindrical portion of the crown handle .and located intermediate two ofthe grooves 7C. When the partsarein normal position thefstorfi'?d is locatediinidwa'y betweentwo of the stops 6b, with the result that when thehandle isturiiedin one direcf" tion theV stop 7d will contact one" of these two stopsv 6b and when .turned in the 'other direction it will contact the other stop 6b.

They stopsy 6b" arearranged at the end of radial lines passing through the center of the grooves 6` so that, when the' crown handle isturne'd and tlielstops arein con-VV tact, the handle has reached'its eXtreme posi?v tionV of oscillation and 'cannot be oscillated any lfartherby reason of the positive stopping means thus provided.Vv Heretofore when no positive stops were. employed and reliance wasplaced 'uponlthe 'ends`ofthe grooves 6a! for stopping purposes, the-balls would ride upon the intervening space between the grooves 6a and would stick" thereon-,with the result that the valve would `be held open and the waterV permitted to waste. Y

vThe cylindrical portion of vthe crown handle is provided with a central circular recess into' which the outer end of the yvalve steine extends and which receives the adjusting nut9; n By preference/balls 10 acting as bearings are provided between the nut and the bottom ofthe recess off/the crown handle.v The nut screws uponfthe screw-threaded end of the valve whereby the position oi the stem and its valve relative to the handle may be adjusted and provision thereby made for the proper seating ot the valve in case of wear. valve stein and crown handle are held in proper relativeV position by means of` the coiled spring 11 whichnorinally holds the valve seated.

The adjusting nut and valve stem are providedl with' means tor locking them together, constituting another feature of my invention. made tubula1 at its outer end to receive a coiled spring 12 and such end is provided with diametrically opposite slots 5l". The adjusting nut has a central counterbore opening, thelarger of which is screw threaded to screw upon the screw threads of the outer end of the valve stem and the' vid-ing shoulders 13 on its opposite edges.`

The narrower portion ot this plate extends i'ipwardly through the smaller bore of the nut and into the slot 9b thereof. This plate is heldl projected in such normal position as shown in Fig. 1 by means ot the coiled spring lVhen in such position the plate locks the adjusting nut and valve stem together, that is prevents any rotation of the nut that would destroy the said adjustment. lllheinhowever, it is desired to make .a new adjustment the construction is such that the locking device is unlocked as an incident to the act of applying,v a tool such as a screwdriver to the nut and turning the same. TWhen the screw-driventor instance is insertedr in the slot 9b of lthe nut it necessarily contacts the upper end ot the locking plate 13 which is thereby forced downwardly7 against the tensionA of its spring. lllhen the plate has thus been depressed below the planel of this slot the nut is tree to be turned in the proper direction toradjustment purposes, and when the tool is removed from the nut and the latter is in such position that its slot 9B will register with the slots 5a thelocking plate will at once be projected outwardly to locking position by means of its spring. The locking plate 13' is limited or stopped in its upward projection by means of the contact between its shoulders 13 and theinterior shoulders 9Z1 of the nut. lt will be understood that the cavity or recess of .the crown handle is closed by the removable plug 14.

By reason of the provision of the stop stem TheA Yin` the ordinary construction.

l As shown the valve stem is iueiubcrs G" and l the movement of the crown handle in both directions is limited, thereby preventing any binding or wedging action of the balls such as frequently occurs lVhen the parts are in normal` position the stop member 7d" ismidway between two adjacent stop members G" so thatthe handle may be oscillatedl in either direction but stopped when the member 7d comes in contact with either one of said two adjacent stops 6b. By the provision of three eqi'iidistantly spaced stops 6b the crown handle in being assembled maybe placed in any one of three positions so thatfits stop member 7dl will be positioned between any two of the three stops 6b.
