Application filed March 6,

and 6 is the enclosed core ofthe heel.. 7 is To all whom it may concern:

Be it known that I, EUGENE a citizen of the United States, Chicago, in the eounty'o'f Cook and State of Illinois, have invented certain new and useful Improvements in Resilient Shoe Heels, of which the following is a specification.

The invention relates to improvements in resilient shoe heels.

One of the objects of the invention is to provide a resilient heel for shoes that may be sold at a price in competition with a rubber lift.

Another object is to provide an inside core for a rubber heel, made of cheaper, and preferably lighter material, such for example as cork, ground leather, sawdust or other fibrous, comminuted suitable shape and made homogeneous with a binder which will render the composition a de- L. De Vania,

gree and tenacious.

Another object is to mold a rubber casing and insert the core therein, or to vulcanize the casing around the core.

Another object is to provide perforations for nail holes thru the core, at spaced-apart intervals, to receive the attaching nails and to. provide small nicks in the tread surfaceof the heel, to indicate the position of the respective holes, as guides for driving the nails, thru the structure.

Another object is to shape the core so that a larger quantity of rubber than elsewhere will be included between the rear end and sides of the core and the thread surfaceof the heel,'to produce greater resilience at this part of the heel, and to provide a larger quantity of rubber where the greatest wear occurs and to cushion the impact produced by the foot of the wearer in walking.

Other, further and specific objects of the I invention will become readily apparent from I acters are employed rubber housing or casing a consideration of the following description when taken in conjunction with the drawings, wherein Fig. 1 is an inverted plan view.

Fig. 2 is a section taken on line 2-2 of Fl%. 1; I F ig. 3 is a section taken on line 3-7-3 of ln all the views the same reference charto indicate similar arts.

the rear portion ofthe heel and 8 is the front portion. The rubber casing or housing 5 is provided with an ed e 10 formed by the concave surface 9 to fit t e rounded sole of a shoe. This surface corresponds to the convex surface of the sole ,underlying the heel, so that when the heel is nailed on to the sole of the shoe, the salient edges closely to the sole, being pressed into contact therewith by the more or less resilient eliect oi the rubber of which the housmg is composed. The core 6 is turned upwardly at its ends, as at 11, and the housing is provided with a surrounding rim 12 which holds the core in place when the core and the housing are made separately and the core inserted therein. ized around the core, which it may be, then the portion between the two lines, as at 13', will cover the core and entirely enclose it, a part of this being the bead shown at 12.

The core may be made of granular, or comrninuted fibrous material, such, preferably as cork molded into form by use of a suitable binder which will produce ahomogeneous material, and render the material more or less resilient and light and well adapted for the purpose. Ground leather, saw dust, or other light fibrous substances 10 will- If the. housing is vulcan-.

such, for instance as papier mach, suitably coated, or fibrous asbestos capable of withstanding the tem erature of vulcanization, may be employe when the core is to be entirely enclosed within the rubber casing.

The core may tions 13 at intervals thru which todrive nails to hold the heel in place and the rubber coating on the tread surface of the heel may have nicks or indentations 14 in line with the respective holes to indicate the holes and to be more readily driven thru the structure. i

When the heel is'in place the core as well as the rubber covering will be securely held on the shoe.

When the nails are driven thru the structure, the heads may be submerged in the rubber below the rubber tread surface with their heads resting on the harder and less resilient core.

In making the heel for an insertable core,

have nail holes or perfora necessazy 0 extend or stretch the rugber when lnSQl'tflflQ' the core. This serves to hold the cover more intimately in Contact with the core and ii slightly flares the, vertical edgy-s of i116 heel to make it mnl'umi to the standard typv of likil.

Having (.lQFCIliiEfKl my il'lViIltlOfi, what I claim as new ml desire to sucum by Lattvrs Patent is A heel comprising :1 block of resilient inaiei'ial ha ing; in: upper face (EON-(l out to leave the sillvs and botom relatively thin;

a care of relatively rigid, light: material having its rear and side edges rounded, tapering and sharply bent its immediate e lge$ and leaving its front edge in a horizontal plane and of uniform thickness, said core a lapteil to fit neatly within the cavity 01" the block, and a cover ing of impervious imiiezfial (in top (if the core, aml sealed in the edges Of the black.

In testimony whereof I hereunto subsvr'ibeil my name.
