RUBBER HEEL.

Application filed October 12, 1926. Serial No. 141,150.

This invention felates to improvements in lustrating a slight modification in the man- :rubberv heels for boots, shoes and the'like, lner of. securing the rubber heel in place,

When the metal plate 5 is exposed as the resultof the wearing away of the rubber heel 4, it provides a smooth wear resisting surface that will not scratch or otherwise mar floors and floor coverings. The vertical dimension of the bosses 7 is greaterthan the corresponding dimension of the heads of' the elements securing the rubber heel 4 in place. In view thereof, the heads of the securing elements are located above the metal plate 5. All possibility of any projection .of the heads below the metal plate 5 is thus avoided. The heads of the attaching elements cannot scratch or otherwise'mar iioors 5 `and floor coverings, especially when the plate is ex osed as the result of the wearing away of t e rubber heel 4, and there is no possibility of the attaching elements, es-

pecially the nails 11 from being forced up -Wardly into the boot or shoe.

4It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions'. Furthermore, the said drawing is illustrative of a preferred construction, it being my expectation that various changes and modifications may be made Without departing from the spirit and scope of my invention. What is claimed is A .rubber heel having a metal anchoring and reenforcing plate embedded therein, said plate being vprovided withV upstanding hollow bosses provided at their upper ends with interior annular iianges, the bosses termihating short of the upper side of the heel and portions of said side of the heel extending across and contacting with the upper ends of the bosses and their lianges,\and attaching elements for securing'the heel in place passing through the bosses and. having their heads arrangedcompletely above the lowersurface of the said plate and in contact with the under sides of said flanges, said construction preventin contact of thehea'ds with a ioor shoul the plate become eX- posed, and openings being formed in the rubber heel below and-in alinement with the bosses.

In ltestimony whereof I affix my signature.
