To all whom it may oonoev' n; I

Be it' known that :I, JoHN H. BA MER, a citizen of the United States of America,

and resident of Maplewood, llftll county ofEss'e: and Sta te of New Jersey; have invented afn'ew" and Improved Anchoring "Shank for Bathroom" Fixtures, of which thefollowing is"afull,"*c 1ear, and exact description.

This "IIIVGHtlOIf relates to-'--anchor1-'ng- "deserted in a recess or pocket formed in the :bathrobnrwall' and maintained in place by 'emb'ednient m a -c'ementit1ous substance within the pocket'or recess;

One *ofthe outstaiiding' objects of "the "invention is to provide an impr'oved anchor ing *slia'nk for fixturesformedor shaped inf suchj amanner "as' 3 to "provide means when embedded 'ina-pocket or 'recess' in a wall filled with a cementi'tious substance whicli"-willfirmly maintain the fixture in place when the substance 'is set and hard-- ened.

As a further object the invention comprehends an anchoring shank which is so constructed as to facilitate the emplacing or embedment of the shank in the pocket or recess filled with the substance.

More specifically the invention embodies an anchoring shank formed with transverse binding grooves within which the ocmentitious substance is received to form a key to positively preclude accidental displacement.

lVith the above recited and other ob}- jects in view, reference is had to the following specification and drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims may be resorted to when found expedient.

In the drawings Figure 1 is a view in perspective of a bathroom fixture having an integrally formed shank constructed in accordance with the principles of my invention.

Fig; 2 is aside view of"thesame showing the shank embedded in cement.

integrally formed with thebase *of 'the I nxture.

Referring to thedrawings' by characters reference 1 designates thebase of adixture which in the-presentinstance is illustrated as atowel bar post or brack t eluding an=arin 2"and a socket 3. The fixture attaching "means consists "of an anchoring shank 4t projecting rearwardly from the center of the base 1 which shank is in'the nature of a fru'strum ofa'pyramid; that 1s, being of gradually i creasing siae' from the reduced end 5 atthe' juncture with'the' base to its outer 'free end. Extending "longitudinally ot the'fshank and formed in opposite "faces thereof, are' arouately shaped grooves 6 which decrease-in depth from the outer free end 7 of the shank to a point'adjacenttheinner reduced end 5. Thelen'gth of the-grooves is'such that they terminate short of the morltlnbr opening of thepocket or recess-8 formed in the wall 9. It'will'benoted'that'whilethe opposing outer"surfaces of the wallsof the relation to the recess, that the grooves 6 converge in the same direction so that the cementitious material C is wedged or urged toward the mouth or open end of the recess or pocket 8 as the shank is forced inwardly.

In order to provide means for further retaining the shank in anchored relation within the cement filled pocket or recess, the opposing faces of the shank provided with the arcuate grooves 6 are also provided with transversely disposed binding grooves 10 and 11 intersecting the grooves 6 and disposed in staggered relation so that the groove 10 is located adjacent the free end of the shank while the groove 11 is located adjacent the inner terminus of the arcuate in fiat contact with the outer surtaceot the wall. In some instances however where it is desirable the outer face of the base may be brought into flush relation with the outer surface of the wall by enlarging the recess or pocket at its outer end for this purpose. It is of course to be understood that the pocket or recess 8 is of sutlicient depth so that when the fixture is properly positioned the inner free end 7 ol the shank will be spaced from the inner wall of the recess.

The cementitious material fills the binding grooves 10 and 11 and when set or hardened produces the keys K which positively preclude displacement of the fixture. ine keys thus formed together with the arrange ment of the larger end of the anchoring shank innermost sets up a double locking action which eliminates any possibility of locseness of the shank when the usual shrinkage of the eementitious material or substance occurs.

I claim:

1. An anchoring device for fixtures comprising a shank connected to a fixture and in the shape of a trustrum of a pyramid, the free end of which having a larger cross sectional area than the end secured to the fixture, a pair of the opposite sides of the shank being provided with grooves transversely disposed 0t said shank and grooves formed longitudinally of the shank and decreasing in depth from the tree end ot said shank to points adjacent the attached end.

2. An anchoring device for fixtures comprising a shank connected to a fixture and in the shape of a. frustrum of a pyramid, the free end of which having a larger cross sectional area than the end secured to the fixture, a pair of the opposite sides of the shank being provided with grooves transversely disposed of said shank and grooves formed longitudinally of the shank and decreasing in depth from the free end of said shank to points adjacent the attached end, one of the longitudinally disposed grooves crossing the transverse groove, the other longitudinal groove terminating at the other transverse groove.

3. An anchoring device for fixtures comprising a shank connected to a fixture, said shank being provided with a. transverse groove adjacent its free end and a transverse groove adjacent its attached end and longitudinally disposed grooves adjacent the transverse grooves and in communication with the transverse grooves.

4. An anchoring device for fixtures comprising a shank adapted to be connected to a fixture, the free end of the shank being longer than the attached end, said shank being provided with spaced longitudinal grooves and transverse grooves extending across the longitudinal grooves.

5. An anchoring device for fixtures comprising a shank adapted to be connected to a fixture and provided with transverse grooves disposed in staggered relation.

6. A fixture having a base, a shank projecting from the base and having its tree end of greater cross sectional area than the attached end, said shank having a groove disposed upon an opposite side of the longitudinal axis of the shank and running transversely of said axis.
