CUSHION-HEELI To a-ZZ 'whom it may concern: i i

Be it known that I, ALFRED BUcoLo, a subject of the King of Italy, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Cushion-Heels, of which the following is a specification; p

The object of my present invention is the provision of a cushion heel possessed of great suction capacity in addition to other practical advantages, and this notwithstanding the fact that the heel is susceptible of cheap production.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof z Figure 1 is an inverted plan view of a cushion heel constructed in accordance with my invention.

Fig. 2 is a top plan view of the heel.

Fig. 3 is a longitudinal vertical section showing the cushion heel as properly attached to the leather heel lifts of a Shoe.

Fig. 4 is a transverse section of the cush ion heel, taken in the plane indicated by the line 4-4 of Fig. l.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In common with cushion heels at present =in general use my novel cushion heel 1 is for-med in one piece of vulcanized rubber or other appropriate resilient material compatible with its purpose.

In its underside my novel heel 1 is provided with a vacuum chanber 2 which is preferably, though not necessarly, of stepped formation and is closed at its top by the wall 3, this provision being advantageous inasmuch as the wall 3 is enabled to prevent water from reaching the lifts 4 of the shoe heel and deteriorating said lifts. The heel 1 is also provided with nail holes 5 and with small suction chambers 6 which reach from the said nail holes 5 to the under surface of the heel. At its underside the heel 1 is provided with integral projections 7 and with an auXiliary suction chamber 8 the said chamber 8 being formed by the curvilinear rib 9 and the transverse rib 10. It will be understood by comparison of Figs. l and 2 that the projectons 7 are arranged slightly in front of the transverse median line of the heel, and the suction Specificati'on of Letters Patent.

chamber 8 is arranged at the rear of the heel, and by particular"referenceto Fig. 3 it will be noted that the. the ribs 9 and 10 are of squarely on the surface.

It

will also be understood that after afew PEATENIT OFFICE,

projections, 7 and i a `,common depth. From this it follows that incident to the use prevent slipping of the weeks of wear, the projections 7 and the ribs t 9 and l0 willbe worn away so that' the surface ll of theheel will pavement or the like. At this latter time the suction chamber 2 will come into play and will effectively prevent slipping of the heel on a wet pavement or other surface.

y virtue of the provision of the projections 7 and the ribs 9 and 10 the heel is adapted to be worn for a material time without any wear whatever of the body of the maj or portion of the heel, and from this it fol* lows that the projections 7 and the ribs 9 and 10 are calculated to prolong the usefulness of the heel considered as a unit. At its upper side the heel 1 is provided with a U-shaped marginal fiange 12, the outer and inner corners of which are rounded as indicated by 13 and 14, respectively, F ig. 4, so that when the heel l is applied to a lift 4 and nails 15 are driven through the nail holes 5 and into the lifts 4, the portion of the heel l within the flange 12 will be carried to and snugly held against the lowermost lift 4, and at the same time the edge portion of the heel 1 will b e snugl y crowded against the lowermost lift, with the result that a neat finish will be produced and at the same time water will be prevented from entering between the cushion heel 1 and the lowermost lift 4. This will be better understood when it is stated that were the corners 13 and 14 sharp right angle corners, the compression of the heel 1 incident to its application to the heel lifts 4 would be attended by spreading of th e fiange 12 so that the uppermost portion of the heel 1 would be of greater area than the portion of the heel 1 below said uppermost portion and in consequence the applied heel would not be as neat and finished in appearance as the heel characterzed by the rounded corners 13 and 14. The edges of the heel l are preferably shaped as shown so that the be presented to a' area of the underside of the cushion heel l t heeli lifts 4 with the result that the` cushion Ifeel will be possessed of a large exposed surace. i v Having described my invention, what I claim and desire to secure by Letters Pat-` psed in rear. of the first-named slotion' d .auxiliary suction 'cham chamber; the sai ber being formed by pendent curvilinear and cross rib's, and the said projections and ribs being of a common height. i

2. As a new article' of manufa'oture, a; cushionheel having in its underside a suction chaiber closed at its top, and also hay ing pendent projectons spaced apart in front of the transverse medianline of the i w article of manufacture, a

heel, and an auxiliary sucton chamber disposed in rear of the first-named 'suotion chamber; the said anxiliary suction ohamber being formed by pendent curvlinear and cross ribs, and the said projectons and ribs being of a common height, and the said heel also having at its upper side a U-shaped -fiangethe outer and inner cornersof which are rounded. i i

3. A cushon heel having'at the underside oi: its real' portion a, su'ction charnbe'r `and alsohaving at its underside and spaced apat and' in front of the sucton chamber pendent proj ections; the said suction Cham ber being defined by a curyilinear rib and a connecting rib and the said ribs andthe said projectionsbeing'ofa commonheight, whereby the ,said suction 'chamber is adapted to serve until the rbs and pendent projections are worn away.

In testimony whereof I afliX my signature.
