t HEEL BASE FOR SHOES.

Appleman meazuiy 7,'

This inventionrelates to a sho'ehaving an attached heel and including aheel base interposed between the heel endportion of the outsole and the heel, and having a flat outer face conforming to the top or inner tace oi the heel,`which is attached to the shoe by nails or like fasteners, extending 'through the heel base.

The object of the invention is to provide, at a minimum expense, an articleof manu,-v

actureconstituting a heel base of strong, durable, and practically non-distortablejconstruction, and including an exposed body portion composed of layers of compressible material, suoli as leather, or a leather substitute, and a reinforcing or stifening layer oit sheet metal, which permits the use of relatively cheap flexible material, such asv low grade leather, or various cheap substitutes for leather, as the, material or 1naterials of which the body portion ot' the base is made. y

My improved heel base includes a lift- 1928. seriiaiNo. a9o,931`..-

shaped body portion composed ot layersof material such as leather, or a leather substitute which is sufliciently compressible to permit the hereinafter described external form to he imparted to said vbody portion by suitable forming instrumentalitics. The base includesalso a stiffeninglayer 17, of sheet metal, entirely concealed by the body portion when the base is incorporatedin a shoe. The layers of whichthe body portion is composed, are formed, assembled, 4

coated with cement, and united under pres sure, to provide at the inner side of the base, a recessed or concaveinner `face formed to bear on the bulging or convex outer face of the heel endportion ofv the outsole 13,

' andfat the outer side of the base a substantiallv flat face. formed to bear on the inner' or top face oi the heel 14. .Y

AThe body portion of the improved heel base includes a body layer v of ,flexible compressible material, such as leather, 0r al leather substitute, having acurved margin 21, and a breast margin 22, the layer being heel-shaped, and its area being less than that of the completed base. Said body portion 'also includes an outer rand 23, .and an innerv rand 24,- saidfrands being of ycompressible.

leathenf The stfening layer. 17 is an ob-..

the body layer 20 and spaced from` the breast edge 22'thereof. The stifening layer is cemented to the body layer, and is provided at its midlength portion with downwardly projecting spurs 27 which are preferably formed byr punching the strip to downwardly ydisplace portions of the metal thereof constituting elongatedgspurs which are pressed into the body layer 2O and increase the stiffness of the strip. The Aend portions of the stit'fening strip are provided with upwardly projecting spurs 26, which are preferably burs formed by punching thek strip lends, and are pressed into the upper v y rand 23, as shown by Figure 3.

The thicker edge lportions of the rands areY cemented together outside the vcurved edge portions overlap and arecemented to portionsv of the sides of said layer, the thin 'edge portion of. the outer rand 23 being cemented also tothe end portions of the stiffbase is provided with a dished face, conforming to the under side of the heel end of the outsole 13, and the inner side is provided with a flat face conforming to the top of the heel 14. The molding pressure some- `what'curves the marginal portion 21 of the body layer and the end portions of the stiffening strip, as shownby Figures 3 and t,

It will now be seen that the stifening strip, engaged as described with the body layer 20, and the outer rand 23, maintains the molded form of the heel base and prevents deformation of the same by warliing or otherwise, while it is carried in stock.

The stiifeni'ng strip is narrow, so that its ends are formed to project between adjacent heel attaching nails 16, the positions of which are indicated by dotted lines in Figure l, so that the strip does not interfere with the nails.

rthe ends of the rands 23 and 24 may be flush with the breast edge 22 of the body layer 20, sufficient surplus material being provided to lpermit the trimming of said ends and edge by a breasting knife. The stifening strip, although narrow, has been found to impart to the heel base such strength and resistance to deformation that the rands and body layer may be made of iess substantial and expensive material than would otherwise be necessary; The described heel base may be sold to shoe manufacturers as an article of manufacture.

I claim: l

l. A heel base formed to be interposed between the convex face of the heel end of an outsole and the top face of a heel, said base comprising a body layer having a curved margin and a breast margin imparting a heel shape to the layer, an outer and an inner rand, the thicker edge portions of Athe rands beingcementedntogether outside breast edge thereof, and overlapped, cov-v ered and concealed at its end portionsby the outer rand, said strip being engaged with the body layer and outer rand, so that the strip maintains the molded form of the heel base.

2. A heel base as specifiedV by claim l, the Y end portions of the stifliening strip being provided with upwardly projecting spurs engaging the outer rand, and its midlength portion with downwardly projecting elongated spurs engaging the body layer and stiffening the strip. V l

3. A heel base as specified by claim l, the

ends of the stiffening strip being narrower thanl the spaces between the nails which attach the heel base and a heel, so that when the base is incorporated in a shoe, the ends of the strip are located between adjacenty nails. A

In testimony whereof Ifliave affixed my signature.
