a 6 Claims- While applicable to ordinary valve, structures, our improvements embody particular advantages in bath "supply valves and the like.wherein frequent" valve operation occurs and alsoin which it isfreq'uently necessary to replace valve seats dimensions in roughing-in is conveniently overcome. r

\ As hereinafter described, another important advantage lies in the fact that by the substitution of either a-single one or a -multiplicity of or Closures principally because of abuse, as for 'spacing washers the journalling centerpiece may example, the failure to'close the valve properly,

or because of abnormal wear due to excessive frequency of operation. 7

An important object of the invention lies in the provision that the actuating member may also serve equally well in the capacity of an escutcheon or protective cover for the operat ing parts. This construction, lends itself to an economical installation, permitting greater ease of eleansibility with exceptional compactness re-, sulting from the omissionof the usual separate and protruding valve operating means.

One of the important objects of the invention lies in the fact that all of the operating parts are constructed and assembled in such a manner thatno special types of wrenches or tools are required .to remove any of the parts either for inspection or repair, and therefore the equipment will be maintained in improved condition withless inconvenience than heretofore.

More specifically, an [important advantage lies in the fact that the lower end of the center-.

piece is broached or otherwiseformed polygonally in order to engage a complementary polygonal shape on the upper end of the renewable seat unit, thereby facilitating easy removal of the latter.-

It is a further important object that for concealed bath and shower fixtures which are necessarily mounted within and behind walls, a new and readily expandible construction has been devised which provides for simple adjustment to allow for the many variations which are encountered in the roughing-in dimensions during the course of installation. With more particularity,

/ therefore, an advantage of the construction lies in making the operating stem with an exposed end which is broached for a considerable distance greater than the length of the broaching through the operating handle so that the end of the stem can easily be made to suit the'roughingin dimension required, by the simple expedient of cutting the length of the stem to the desired size. In so doing. the handle can be maintained approximately'the same distance from the face of the wall for'all reasonably variable installations. 'By'such novel arrangement, obviously, the objectionate provision requiring different lengths or sizes of stems to take care of the varying Other objects and advantages of the inven [tion will appear from a reading of the specification which follows in connection with the patent drawing, in which: 1

Fig. l isa central vertical sectional assembly of a preferred embodiment of the valve and its operating mechanism. I

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1, illustrating a preferred form of non-rotatable relation between the centerpiece and the sleeve.

Referring to Fig. 1 of the drawing, the numeral l designates the casing or valve body which is provided with the conventional inlet 2 or 3 or both, as the installation may require, and with the side outlet lb. Centrally positioned within the casing I and dividing the latter into chambers separating theinlet from the outlet, a dividing Wall or diaphragm Ia has its transverse wall apertured for the threaded seat opening' 4* into which the sleeve 5 is threadedly retained. The lower portion of the saidsleeve 5 disc or closure 1 abuts when in seated relation thereto, and, as indicated at 5a, the sleeve is counterbored slightly larger than the bore pr seat opening 20, in reducing objectionable flow noises, and a similar result is accomplished in making the face of the disc 1 flush with the outer edge of the retainer ring .II, as indicated at Ha. Further, and also for this purpose, the disc 1 is recessed as at 1a to receive the shoulder of the lower stem 8. The disc 1 is removably connected in the usual manner to the winged lower stem 8 by means of the threaded extension 9, the retainer ring II and the threaded nut l2. Below the winged guide, as indicated at 8a, the lower stem diameter is substantially reduced so as to provide an adequate flow space as at 20, and thereby also minimizing water-flow noises, The lower stem 8 is preferably integrally provided with the narrow extending shank l3 havis provided with the seat 6 against which the- I to guide the spiral spring l5, as illustrated, serves as a retainer for the spring at one end, while at the other end it is -will likewise be rotated.

It while the shoulder retained by the shoulder ll of the sleeve 5. Beyond the shoulder I5 the shank l3 preferably resumes its narrow nating in the roughened or 19 fitting Within 'the hollow stem or valve actuating means of the knurled end portion 2| of the threaded of the loosened unit 22 is threadedly journalled within the centerpiece 23 so that by its rotation in one direction or the other, it is either moved toward the valve closure or is moved away from the closure. The

centerpiece 23 is held in abutting non-rotatablerelation against the annular threaded end of the casing l bymeans of the threads 24. While only a single gasket isshown interposed at the said threaded'end 24, several superposed spacing gaskets may be provided at this point for the purpose" of maintaining the desired clearance between the: upper and lower stems, .as indicated at l9 and 21a, and within the recess 2lll, so that the said clearance does not permit too much rotational travel of the stem 22 before contactingwith the knurled end l9 and thereafter forcing the disc I from the casing seat 6.

As shown more clearly in the transverse section of Fig. 2, the sleeve 5 is of polygonal cross- ,section in its outer contour and is enclosed with in a similar polygonal-shaped recess. Thus, by the rotation of the centerpiece 23,,as accomplished by the application of an ordinary wrench to the polygonal-shaped shoulder 26, the sleeve By ,so doing, the threaded joint at 4 will be broken, thus allow-V ing for the removal, as a unit, of the disc I, the

- a practical coverto conceal the otherwise exdisc retainer H, the nut 9, and the winged lower stem 8, together with the sleeve 5. Either the fingers or pliers may be used to grip the knurled end l9 and remove the assembly just described.

In order to maintain the centerpiece 23 in fixed and non-rotatable relation with respect to the upper portion of the casing I, the threaded bonnet 25, by means of its screw threads which engage the, complementary casing threads 24, clamps the shoulder 26 therebetween in the preferably adjustable gasketed joint as previously described, and also serving thereby to confine the packing 28 within its inverted recess 21. An annular hollow plate 29 tion against the wall threaded locking ring 32. stem 22 is-provided with section 33 and with relatively long internal threads 34 for engagement by the capscrew 35 which holds the escutcheon handle 36 which is suitably broached as at 31 to fit non-rotatably upon the said stem broaching '33., Thus it will be evident that by the construction just described the broached end portion of the stem 22 may be conveniently cut off to suit the roughing-in variations, and by providing an overhanging or escutcheon type of operating 36, there is provided not only an effective operating means, but at the same time it serves as line 3| by means of the The actuating upper It is further evident that the exposed parts.

Upon reversing the direction of rotation of the operating escutcheon handle, the stem is caused to recede and thus allows-for the disc to return to its seat, under the force exerted by the spring l6 as well as that of the line pressure. Thus.

we have accomplished a relatively quiet valve m the purpose, capable of being easily suited to" variations in installation and capable of repair with minimum of inconvenience and! possessing ease of operation. V i
