E. B. CINTRON S-HOE HEEL Oct. 24, 1944.

Filed July 50, 1943 Y E O T T Patented Oct. 24, 1944 UNITED STATES PATENT OFFICE SHOE HEEL Ezequiel B. Cintron, New York, N. Application July 30, 1943, Serial No. 496,721

7 Claims.

This invention relates to heels for shoes and more particularly to replaceable inserts for both rubber and leather heels.

Applicant is aware that heels with replaceable inserts have been made but in such heels it has been very difiicult to remove the'damaged portion or insert of the heel, and the heel is often damaged in the removal thereof. Furthermore it has been very difiicult for anyone not a shoemaker to either detach or attach such inserts. Also it has been very difficult for a person not skilled to properly position the insert with the remainder of the heel. In addition, it takes a skilled worker to fasten such inserts on to the heel.

It is an object of my invention to make it easy to detach the worn portion or insert of the heel without damaging the rest of the heel.

It is a further object to make it easy to attach a new insert.

Another object is to provide ready means for automatically guiding the insert into proper position on the heel with its wearing surface even with the wearing surface of the remainder of the heel.

Still another object is to provide means for securely fastening the insert on the heel without the use of tools.

These and other objects of the invention will be apparent from the description thereof to follow taken in connection with the accompanying drawing, in which- Fig. 1 is a perspective view of one form of my improved heel attached to a shoe.

Fig. 2 is a bottom plan View of the improved heel of Fig. 1.

Fig. 3 is a bottom plan view of the replaceable insert removed from the rest of the heel.

' Fig. 4 is a bottom plane view of the heel of Fig. 1 with the replaceable insert portion removed, and parts being broken away.

Fig. 5 is a cross sectional view of the replaceable insert taken on the plane of the line 5-5 of Fig. 3.

Fig. 6 is a cross sectional view taken on the plane of the line 6-B of Fig. 4.

Fig. 7 is a plan view of a modified form of leather heel embodying my invention.

Fig. 8 is a, plan view of the form of Fig. '7 with the replaceable insert removed.

Fig. 9 is a cross sectional view of a part of the heel of Fig. 7.

Referring to Figs. 1 to 6, inclusive, an ordinary shoe I0 is shown with an ordinary leather heel or lift il. My improved rubber heel is mounted on the lift l I and comprises a rubber body portion ii. of the usual standard size to fit the standard size heel or lift. It is preferable howslightly thicker than the ordinary rubber heel. This portion I2 is formed with a cut-away portion 13 resulting in a reduced portion 14 extending from substantially the center of the body portion 12 to its rear edge. The forward thickened portion of the body portion I2 has its rear wall i5 cut at a. bevel or slant providing an overhanging edge IG, which edge may be reinforced by using harder rubber material at this point, or in any other suitable Way.

The improved rubber heel is fastened to the lift I i by nails or screws I1 driven through wash-.

er members i8 into the lift 1 I. The washer members it? are joined together by metal strips i9 which strips and washer members form a frame embedded in the body portion 12 and reduced portion l4.

On the reduced portion I4 of the rubber heel is an insert 28 of the same material and of the same shape as the cut-away portion. This insert is detachable and when in position its outer wearing surface is even or flush with the outer Wearing surface of the thickened body portion I2. Its inner wall or edge 2i is beveled or cut on a slant to accommodate and fit the adjacent slanted inner wall i5 of the thickened body portion.

This detachable insert 20 is fastened to the reduced portion M by means of outwardly protruding spaced headless prongs or studs 22 adapted to be inserted into spaced openings 23 in the under surface of the insert 20. The studs 22 may have their surfaces roughened in order to more securely engage the walls of the openings 23. At about the center of the reduced portion I4 is a protruding stud 24 having a knob or enlarged portion at its top end. This stud 24 is adapted to be snapped into a metal snap fastener or socket member 25 on theunder surface of the detachable insert 20. The studs 22 and 24 are connected to the metal frame formed by the strips l9 and with the washer members 18 form a unitary structure which holds the studs and washers rigidly in position.

In attaching the replaceable insert 20 on to the heel, its slanting edge wall 2| is placed against the slanting wall l5 of the thickened portion at which time the openings 23 in the insert will be directly over the studs 22 and the socket 25 will be directly over the stud 2d. The insert is then pressed downwardly with the hand and the studs 22 will be driven into the openings 23 and socket 25 will be snapped over the knob of stud 24. These coacting studs, openings and socket will securely hold the replaceable insert on the rubber heel.

In order to detach the portion or insert 20 after it has been worn at the rear rimor for any other reason, a suitable tool is inserted underneath its inner surface at the rear edge. In

order to facilitate the reception of such a tool and to prevent damage to the adjacent surfaces of the thickened portion and of the replaceable insert, I have provided a metal strip or plate 26 suitably fastened to the outer surface of the reduced portion 14 at its rim. The detaching tool is inserted over the top of the plate 26 and the detachable insert 20 is lifted up and off of the heel.

The outer surface of the reduced portion I4 is provided with grooves 21 for coacting with grooved portions 28 on the inner surface of the detachable insert 20 in order to assist in securing the detachable portion and prevent squeaking of the heel. These grooved and ribbed surfaces are covered with a thin coating of rubber cement in order to assist the studs and sockets in holding the detachable insert on the heel.

In Figs. '7 to 9 is shown an improved leather heel with a replaceable insert. In this form, the heel 30 formed of leather has a thickened portion 3l and a reduced portion 32 of the same shape as the thickened portion [2 and reduced portion M of the form shown. in Figs. 1 to 6, inclusive. In this leather heel, a reinforcing metal strip 33 is fastened on the top of the overhanging edge 34 of the thickened portion 3|. In this form, the leather heel is fastened to the lift and solefof the shoe by nails 35 passing through the thickened portion 3| and nails 36 driven through the reduced portion 32.

The replaceable insert 31 is of the same shape as the replaceable insert or portion 20 of Fig. l and is fastened to the reduced portion 32 in the same manner as said insert 20 by means of the studs 22 and stud 24 engaging in openings 23 and socket 25, respectively.

This leather heel has no washer members l8 or strips l9 as in the case of the rubber heel of Fig. 1.

The coacting surfaces of the reduced portion 32 and replaceable insert 31 may be grooved and these surfaces are coated with rubber cement to insure the holding of the parts.
