FASTENER FOR RUBBER HEELS Filed 001;. 4, 1927 L g/ mu: If

Ill urume 1 I J W ATTORNEY Patented May 5, 1931 PATENT OFFICE LU IGI PIGNANELLI, OF TACOMA, WASHI NGTON FASTENEE FOR RUBBER HEELS Application filed October 4, 1927. Serial No. 223,890.

This invention relates to an improved manner and means for securing rubber-heels to shoes in the manufacture-and repair thereof.

Because glue or other cementitious substance has proved unsatisfactory for securing rubberheels to leather shoes recourse is had to nails for this purpose.

Hitherto the nails have been driven through a rubber heel into the leather heel element of a shoe until stopped by the nail heads encountering metal washers'which are embedded in concealed positions within the body of the rubber heel.

The relative positioning in the heel of such metal washers, or nail stops, measures the extent to which a rubber heel may be utilized for when the rubber below the plane of the washers is worn away to expose one or more of the washers, the heel is rendered unfit for 320 further service. Inasmuch as such washers are embedded in a heel at or about its middepth and expose one or more of the washers, rubber heels are proven short lived and much of its material is wasted.

It is the object of the present invention to provide an improved manner or means for securing a rubber-heel to a shoe which will obviate the objections above referred to and which will enablethe rubber material of a heel to be operative until it is worn entirely through, thus prolonging the life of a heel.

, More specific objects and advantages ofthe invention will appear in the following description.

The invention consists in the provision of a member of leather or an equivalent mate rial formed to couple with the rubber a body portion of a heel and adapted to be interposed between such body and the leather heel ele ment of a shoe.

The invention also consists in a heel fastener secured to the top ofa rubber heel and adapted to serve as a member whereby nails may be employed to secure the heel to a shoe,

said fastener being located outside of the rubber structure thereof, thereby'permitting the heel to be used until it is worn entirely through.

The invention further consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a view partly in side elevation and partly in longitudinal vertical section,

showing a portion of a shoe, including a rubber heel which is illustrated as held in place by means of fastening devices embodying the present invention. Fig. 2 is an underside plan view of the rubber heel shown in Fig. 1. Fig. 3 is a plan View ofthe blank from which a heel fasteneris formed. Fig. 4c is a longitudinal sectional view ofthe fastener and Fig. '5 is a similar View of the heel illustrated in Fig; 1, shown detached. Fig. 6 isan underside perspective View of a heel fastener, the design being modified from that illustrated in the preceding views; Fig. 7. is an upperside perspective view of a rubber heel adapted for use with the design of fastener .or an equivalent material having the shape of a heel and is cut or otherwise formed with incisions 151(Fig. to provide a plurality of tongues 16 which are connected at one end, as 17, ofeachtot-he body of the fastener. 'These tongues 16 are turned downwardly from't'he apertures 18 in such body to provide pin elements 16 disposed at right angles to the plane of the body. Said pins, furthermore, are preferably formed into circular c'ross'sections, or nearly so, and rendered rigid by treating the pins with warm paraifiin or other suitable solidifying material.

The rubber heel 13 is provided with holes 19 disposed "to accommodate the respective pins "of the-coupler. 'The rubber heel 13 and the coupler 14 as described above and illustrated in Figs. 7 and 8 are firmly united by means of a suitable adhesive material applied to the several pins and to the contacting surfaces of the rubber-heel and the body of the fastener 14.

The rubber heel 13 and the coupler thus coupled together are secured as a unit to the leather heel element 12 of the shoe by means of nails 20 supplemented, preierably, by an adhesive material applied to the leather surfaces at the joint. The nails 20 extend through the coupler into engagement with the shoe heel element 12, as shown in Fig. 1; and to accommodate the insertion of the nails, and a suitable punch (not shown) for driving the nails, the rubber heel 13 is provided with apertures 21.

lVith shoes having small heels such, for example, as womens shoes, the construction shown in Figs. 1 to 5, inclusive, is found to be most suitable, while with larger heels as, for mens shoes, the design shown in Figs. 6, 7 and 8, is preferable. These embodiments of the invention, however, are for illustrative purposes only and may be varied as to form, number, and arrangement the coupling pins 16 and also with regard to the disposition of the shoe nails 20 for securing a united rubber-heel and its fastener to the shoe proper.

In practice, a rubber heel and its fastener are secured together by engaging the pins 16 of the fastener l l with the rubber heel 13 in the respective holes 21 of the heel. Preferably, this is done after a coating of adhesive material such as glue or cement-has been applied to the pins and also to the under surface of the body of the fastener which contacts with the rubber heel. The rubber-heel and its fastener thus secured together are connected to the heel element 12 of the shoe by means of an intermediate film of an adhesive material.

Nails 20 are then inserted in the holes 21 of the rubber heel and are successively driven therethrough by means of a hammer and a nail punch so that the nails are forced through the fastener 14 until stopped by the nail heads engaging the fastener as shown in Fig. 1.

The construction and manner of using the invention will, it is thought be understood from the foregoing description.

While I have illustrated and described preferred embodiments of the invention, I do not wish to be understood as limiting the invention specifically thereto as changes may be made therefrom within the scope of the appended claims.

hat I claim, is,-

1. A means for securing an apertured rubber-heel to a shoe structure comprising a leather coupler between the shoe structure and the heel, said coupler being provided with pin elements struck-out from the leather coupler inwardly of the peripheral edges thereof and extending downwardly into some of the apertures of the heel and terminating flush with the lower face of the heel, said struck-out pins providing elongated apertures in the coupler forming cushioning air pockets between the shoe structure and rubber heel, and headed nails inserted in other of the heel apertures and driven through the coupler to engage in the shoe structure, the heads of said nails bearing against the coupler.

2. In a means for securing an apertured rubber-heel to a shoe structure, a coupler consisting of a piece of flexible material adapted to be interposed between said structure and the heel and having pin elements struck-out from the flexible piece of material and protruding therefrom to engage the heel in the respective apertures thereof and terminating flush with the tread surface of the rubber heel.
