IMPRovnD ELASTIG CALK Fon Boo'rs Nn saone The Schedule referred to in theseLetters Patent and making parl: of the um To all whom it may concern:

Be it known that I, GILBERT H. OLnMnns, of the city, county, and State of New York, have invented a new and useful article of manufacture, to be applied to the heelsof either boots or shoes, for the purpose of preventing persons, when Wearing them, from slipping when walking upon the ice or snow; and I do declare that the following is a full and exact description thereof, references being made to the Vaccompanying drawings by gures and letters.

The prominent feature in my invention is in con-` structing an ice-heel-calk, of elastic material, which I propose shall be made of soft rubber, being the most suitable substancernow in use. Y

The said ice-heel-calk is intended to be applied to the heels of either boots or shoes, and moulded or formed to iit the size and shape of any heel, and,'when expanded sufiiciently, can be readily placed upon the heel, and, by the elastic 'compression of the rubber,

adhere firmly to its place, and, to a certain extent,` 'produce'a vacuum, causing the sameto remain .very

firm upon `the heel, but, for additional security against a possibility of the saidn heel-calli being thrown oil' the heel when 4in use, I have attached a band to either side of the'said calli, which passes around the instep of either boot or shoe.

The bottom surface of the elastic calk has a series of unbroken curved corrugations, but there may be square or oblong projections substituted in place of the curved corrugations, The object in brming the corrugations in the manner shown, in the place ci' making them checked, as they are applied to the bottoms of rubber shoes, is to produce a greater adhesion to the ice or snow by the flexible co1'rugations,when pressed upon the ice or snow by the weight of the person Wear ing them, ei'ectually excluding the air, and forming a vacuum which will prevent the possibility Yof the foot slipping. v

For additional security against the person slipping when Walking upon ice or snow, I have inserted, from the inside oi" the elastic calk, a metal calk, which is` concave on the bottom surface, and-when the weight of the person wearing the calli presses uponA onev of the calks, the elastic surface will be compressed sulciently to force the metal calk into the ice, and thereby hold the foot securely against slipping.

These metal calks can be removed from the elastic calli, and bey replaced by others, 'or may be dispensed With entirely, or may be constructed in any other suitable form, or more than one may be used.

The elastic calli may also be secured to the heel of a boot or shoe bya conical-headed screw, passing through the said disk, and screwedinto the heel of the boot or shoe.

rlhe following references to the lettersv and iigures marked upon the drawing will further explainmy invention:

Figure l is a side elevation of a portion of the boot or 1shoe,with the elastic calli attachedto the heel, and the red lines show the band attached to said calk, 'and passing over the instep.

Figure 2 is an end elevation of a boot or shoe, with the elastic calk attached.

Figure 3 is a side elevation; with the calk detached from the heel.

Figure 4 is a bottom view of the elastic calk, showing the series of corrugations,.

A represents a boot, With the elastic calk B applied to it. C represents the metal disk, provided with a flange at its' top face, while the lower end is made concave.

What I claim, and desire to secure by Letters Patent, is-

l. A'rubber heel-calli, moulded or made to it on to `a boot or shoe-heel, in combination With the metallic disk C in the bottom of the same, all as and for the purpose specified.

2. A rubber heel-calli, moulded or. made to t on toa boot or shoe-heel, in combination With a band or bands, strap or straps, to pass around the instep of the boot or shoe, for thef'prpose of holding the heel-calli on the heel oi the same, all as shown and described, and for the purpose set forth.

3. A rubber heel-calk, moulded or made to iit on to a boot or shoe-heel, the bottom of which is made With a series of corrugations, constructed substantially as shown and described, and for the purpose specified.
