PLUMBING FIXTURE ADAPTER Filed May 31, 1928 Patented July 26, 1932 UNITED STATES FREDERICK CIKUIINLE, or'oIIIoAeo, ILLINOIS PLUMBING FIXTURE ADAPTER Application led May 31,

My invention is l fixtures. Y

The object of mv invention is the provision of a. simple, inexpensive means for providan adapter for plumbing ing anishing device for plumbing iixtures where the connections are concealed in the wall or partition and the operating mechanism or valve protrudes through the walls. It is peculiarly adapted' to all such plumbing v equipment as is shown in my application-No. 56,399 liledV September 14th1925. f Anillustrative embodiment of my"invenltion isrshown in the attached drawing, but Yit isl only limited thereto as far as Iam l5 limited by the scope of my claims. j

Fig. 1 is an elevation of a valve mechanism with portions exposed to show the internal and external structure1 with a standard porvcelain bonnet. Fig. 2 is a. similar valve structure with my adapter device shown in connection therewith. Fig. 3 is a cross section vof Fig. 2 at the line indicated by arrows.

`In the installation of plumbing fixtures, when a building is being newly constructed the standard process is to install the rough parts in the wall and leave a. protruding portion (with the valve mechanism removed) until after the plastering and finishing work is done. l In the work of the inishers and plasterers the constant tendencyis to not only leave on the iiXture more or less plaster and other injuring iniiuences, but quite orten the portion of the mechanism protruding through the wall becomes injured before the building is complete. `As the exposed portions of plumbing fixtures usually have some nickelingat a point where the fixture comes through the wall the said ixture is oftentimes injured beyond repair; and even if the same could be removed to 'be repaired,'it is ordinarily out of the question. Likewise, in the use of plumbing xtures the nickeled portions are apt towbecome injured in use, and when s uch injury occurs it is impossible to repair it except bv a tearingaway of the wall and removing the entirety of the fixture.

In a large number of cases a porcelain bonying the porcelain bonnet 14are shown 1n my 1928,V Serial No. 281,724.

net orcap is assembled on the valve rod to cover the portionof the fixture extendingout into the room beyond the .Wall finish. As illustrated my device is an adapter for all kinds of valve connections where they extend through thewall, and provides an arrangement .whereby one standard'valve body can f be used and accommodate any type of iinished equipment. 5 kis the body oran ordinary valve combination being the stud por- 50 tion whichextendsfrom the lines running in the partition or the wall out into Athe area designed for service. `At or near the point of the wall connection'I provide a collar or band 6 as an integral/,end portion of thebody extension'orstud 5. I kprovide a shoulder or iianger slightly larger in diameter than the j collar 6 so` that the hereinafter described adapter may snugly pass over 6 and iind its "stopping point at 7. Closely adjacent the an- 6 and bisecting the annular groove 8. ,This

*described member 5` is `made to become a 'standard type in-plumbing equipment ixture Vfor the purposes described; and beingmade a standard casting it can be installed in the processor construction without the danger of suffering any injury from the workmen in rS0 plastering, in finishing, or in the use of their tools The nut 16 for enclosing the valve mechanism, the packing 17, the gland nut 18, and the nipple 13 for attaching andsupportformer pant referred to and are a standard equipment. rVVhen in cases where the porcelain bonnet 14k type of finish is not used, and the other finishes are desired I provide a substantially tubular or adapter shell 1() having a boss or'indent 11 directed inwardly adjacent one end of the shell 10. The purpose of this boss or indent 11 isto form a locking means for the shell; by passing the same down over the collar 6 the indent l'l-follows '95 the groove 9 until it reaches thek annular groove 8 whence by a slight turn the adapter shell is locked upon the body extension. The shell 10 may be any length desired to meet the need. I provide a collar 12 upon a turned CII over portion of the shell to surround the stem of the valve protruding therethrough.

It will be readily seen that this device makes a universally adaptable fixture, as it can be slipped on the fixture after all the building Work has been done and can be made to suit any decoration desired for plumbing work, and the same can be removed at any time at the merest nominal expense by the merest novice, for any changes which may be desired.

This device, though primarily devised to cover the outer end of a fixture having a valve and valve regulating mechanism, is equally adapted to any such plumbing fixture Where the conveying Water pipes are installed in the partition or Wall and an outlet or opening extends from the main line through the partition to a point of accessibility.

I claim 1. A fixture of the character described having on the surface of its outer port-ion an annular band, adjacent said band and approximately near the outlet end an annular groove, adjacent said groove a shoulder of greater diameter than the annular band, a groove in the annular band and communicating with the annular groove.

2. An outlet fixture for the purposes described Wherein the supply pipes are concealed Within a Wall and a protruding portion therefrom extends through the wall, an end portion of said protruding portion having a bearing face, adjacent said bearing face and slightly spaced from the outer end of said protruding portion an annular groove, adjacent said groove and on the opposite side thereof from the bearing face an annular flange or shoulder having a greater circumference than the bearing face, a longitudinal groove in the bearing face extending cross- Wise thereof bisecting the annular groove, and of substantially the same depth as the annular groove.

3. An outlet fixture for the purposes described wherein the supply pipes are concealed Within a Wall and having a protruding portion extending therefronr through the nali, the open end of said protruding portion being internally threaded and having an external annular bearing face, adjacent said bearing face and spaced from the outer end of said protruding portion an annular groove, adjacent said groove and on the opposite side thereof from the bearing face, an annular flange or shoulder having a greater circumference than the bearing face, a longitudinal groove in the face of the bearing extending cross-Wise thereof bisecting the annular groove and of substantially the same depth as the annular groove.

f-l. .ln a device for the purpose described, a. housing having an outlet formed with a bearing surface, an annular groove adjacent to bearing surface, an annular shoulder adjacent the annular groove, a valve stem, nuts threadedly assembled in said outlet adapted to cooperate with the valve stem, packing compressed betiveen said nuts, a covering adapter formed to slidingly operate upon the valve stem and engage said bearing surface and said annular shoulder and having means to engage in the annular groove to loclingly attach the adapter to the outlet of the housing.
