STANLEY SOLARZ, OF ST. PAUL, MINNESOTA.

DETACHABLE SHOE-HEEL.

Application T 0 all whom it may concern:

e it known that I, STANLEY SoLARz, a citizen of Poland, residing at St. Paul, in the county of Ramsey and State of Minnesota, have-invented certain new and useful Improvements in Detachable Shoe-Heels, of which the following is a specification. This invention relates to new and useful for detachably securing heels to shoes, its main object being the provision of heel fastening devices, requiring .in their application absolutely'no cutting away of parts of the shoe proper, such as sinking large cavities, or embedding parts to render them flush with the surface of the shoe.

hen devices of this kind require careful fitting, skilled labor is'required thereby precluding its popular use. 7

An-object of my invention, is to provide a rubber heel which may be purchased and be applied by any unskilled person, the device being. so simple in construction that it may belaid' flatly on the heel portion of the shoe to bring its edges even with those of the latter, and then betapped gently'with a hammer, whereby the shoe'is caused to be plainly marked or indented, so that the part of the device to be secured to the shoe, may be positively located and simply pegged directly" upon the top surface of the shoe, which concludes the operation. 1 A further object of the invention is to provide an element to be cast into the rubber heel, which-will have no large fiat surface areas such as flat plates, whereby the rubber, as is well known, becomes easily separated from the metal and tends to tear the heel asunder, the heel anchor shown in the present invention being of spider design and of springy metal so that it will retain its shape but yield to the bending of the rubber.

A designates a shoe, and B a shallow heel thereon, C designates a to cooperate with the shoe element D to lock the rubber heel to the shoe. E designates a rubber heel of usual contour having in its under face a circular recess 1 having a flat bottom 2, said recess being of slightly increased diameter, at its top. Buried in the rubber beneath said bottom, and having a centrally disposed upwardly extending shank or stud 3, protruding centrally throughthe rubber, is This anchor element is made of springy steel plate, and is formed with a plurality of short radial arms i, and a long radial arm 5, bent upwardly'at its outer extremity to form a lug 6. The shank 3 is capped with a horizontally disposed T head 7, extending at right angles to the arm 5 and in parallism with the lug 6. The T head is curved upwardly at its ends, so as to form curved under surfaces 8 (Fig. 7). As illustrated in Fig. 3, the element'is slightly spaced from the bottom 2 of the recess 1. the arm extending forwardly longitudinally of the shoe and the tip of the lug 6 protruding slightly above the flat under surface 9, of the rubber heel at a position adjacent the breast '10 of the heel, as is best shown in Fig. 2 of the drawings.

Fitting into the recess 1, so as to be revoluble therein without too great frictional engagement, is the pan shaped element D, the pan portion thereof being of a height measured from its rim edge 12 to the outer side of its bottom 13, equal to the depth of the recess 1, see Fig. 3. Centrally, in the bottom of the pan, is the elongated aperture 14, adapted to receive loosely, the T head 7 so that the latter may be projected therethrough.

heel element adapted the anchor element D.

- the fixed heel and extendingforwardly to 13, from the edge 12, and in longitudinal alinement, with the aperture 1 1, is the arm 15, said arm having near its outer end an opening 16, adapted to receive the tip ofthe lug 6. The lug 6 and the opening 16 lie in a circle concentric with the recess 1, so that when vthe T head 7 of the heel, is inserted 1nto5 the aperture .14 of the element on the shoe, (as by placing the heel as indicated by dotted lines tip of the lug will enter the opening 16. Along the edge12 of the element D are a plurality of upstanding teeth bring its edges flush with, a heel portion on the shoe. A

17.7 The'process of mounting the-element D maybe described as follows.

The element is inserted in the heel as above described, bringing the arm 15 to a position indicated in Fig. 2. The heel is nowheld positioned by hand on the shoe to the edges of the ahammer on the top of the rubber heelwill cause the teeth 17 to slightly indent the leather of the shoe. Theelement D. is now removed from the rubber heel andplaced back-on the shoe, care being taken to havethe teeth engage their respective indents in the leather. Pegs or other suitable nails are now inserted in the nail holes 18 and 19 of the element and firmly driven into the leather, the teeth thereby also being driven to bring the edge 12 into engagement with the top of the shoe heel B. Obviously, by

employing the teeth 17, the element is easily and quickly correctly positioned, and as the metal of the element-is very thin the arm 15 need not be sunk flush into the leather, as the nails in the holes 19 drive the armcinto the leather, or mother words, the leather is compressed sufliciently by the blows of the hammer at that'point so as to form a hollow place, with respect to the corners a-a of the heel; Thus no cutting of the heel; is, re-

' quired.- By using a T head as shown, the

curved under sides 8 thereof, operate like a wedgeagainst the edges 20 of the apertures 14, when the heel is turned into alining position. As the .alining position is approached, the rubber-heelis slightly flexed upwardly hand, to permit the lug '16. to pass over the shoe heel, the spring in the metal of the arm 5 imparting a strong spring stress to the heel.-
