SHOE-HEEL.

Specification of Letters Patent.

I Patented Jan. 7, 1919.

Application filed. November '26, 1915. Serial No. 63,353.

To all whom it may concern:

Be it known that I, FRANCIS A. NOLAN, a cltizen of the United States, residing at St.

Paul, in the county of Ramsey and State of permanently secure them to the shoes.

More particularly this invention has to do with that class of resilient heels, which are permanently secured to the shoes or a por tion of the shoe heels. ,With previous devices the fastening means and the particular construction of the heel employed haverendered shoe 'heels of the class stated objectionable due to the fastening means being diflicult to secure in place, rendering the same eflective only part of the time and theshoe heel not preventing slipping at all times and under all conditions- Prior constructions have also in all instances where the cushion heel is fastened permanently by securing fastening devices through the lower surface of the heel, permitted moisture and dirt to collect'in cavitiesor openings which have been provided in the heel. Th'ese objections are entirely overcome by my invention. y invention farther provides an efiiwhich will wear longer and produce more effective results than heretofore. In the accompanying drawing forming part of this specification, Figure 1 is a side elevation of a detail of a shoe, a portion of the heel thereof being shown in section; Fig. 2 is an end view of my improved resilient heel, a portion thereof being broken away and in section; Fi 3 is a bottom plan view; Fig. 4 is a top p an view; Fig. 5 is a section of a detail taken on "the line XX of Fi 4- Fig. 6 is a section taken on the line Y1 of Fig. 4; Figs. 7 and 8 are sections of details, and Fig. 9 is a top plan of an construction. In the drawing A indicates a detail. of a shoe or boot, it being understood that where the term shoe is used throughout this permanent attachspecification and in the claims following, it is intended to be construed as meaning boots, shoes and any other foot wearing apparel h which resilient heels are adapted for use. The shoe A is shown with aportion of the usual heel. portion 2 secured to the lift in the usual manner. B is my improved resilientheel which is adapted for perma nent attachment to the heel portion 2 of the shoe or when desired, it can be permanently secured directly to the lift instead of to the heel portion '2. My improved resilient heel B maybe made out of rubber or other suitable resilient material and is molded or otherwise formed in the shape of the usual heel. The body B of the heel is formed with a cavity 3 in the top side thereof adjacent to the lower surface of the heel portion 2. The rim or margin 4 of the heel surrounding the cavity 3 has embedded in its upper portion a plurality of washers 5, 1

which are suitably spaced apart and through which fastening devices such as the nails 6 are driven from the lower side of the resilient heel upwardly into the body of the heel portion 2 of the shoe. Suitable buttresses'15 are formed on the heel B projecting into the cavity 3 to provide material in which the washers 5 are securely embedded to hold the resilient heel securely on the 5 is dished to shoe. Each of the washers form a recess 8 in its surface through the opening 9 of which the shank 10 ofthe nail or other fastener passes. The recess 8 receives the concave head 11 of the nail, so that the head of the nail will lie flush with the lower side of the washer after the nail has been driven home. By forming the re cess ,in the washer in the manner stated, more wearingmaterial is provided in the body of the heel without wearing the head of the nail and releasing the heel from the shoe. In Figs. '7 and 8, a comparison between the new and old method of construction is illustrated. The recess construction appearing enters. the

' heel portion 2 of through which 'nail 6 or other fastening means is placed in the indenture 13 and the fastening device then driven through the body of the heel toward its upper side. As a result the fastening device is directed so that as it heel it will pass through a corresponding washer and into the body of the the shoe. The wall of the recess 8 which tapers inwardly also acts as a guiding surface-to assist in directing the point of the fastener through the passage the fastener home, a nail set or other instrument or tool is employed which after the home is withdrawn from the resilient heel. The body of the resilient heel thereupon closes the opening which has been made by the nail or fastener, thus sealing the heel and preventing any moisture or dirt collecting in its body, which otherwise would occur were an opening provided in the body of the heel the. nail or fastener is driven. In thismanner the heel is rendered more sanitary which is an advantage.-

The guiding spots formed by the protuberances 12 or other suitable marking means can be of any sutable construction for centering the fastening devices over the respective heel engaging elements formed by the washers 5 or other suitable means. The outer margin of the heel is formed with an upwardly projecting lip 14, due to the upper or heel face of the resilient heel being concave. When the resilient heel is secured with its wear surface outmost upon the shoe, the fastening devices holdthe heel with its margin compressed tightly against the shoeheel or lift, thereby producing a close jomt under compression and causing the heel to compress tightly against the surface upon which it is mounted. The cavity 3 also assists incausing the heel to adhere by suction in place. I

In the manufacture of shoe heels having my invention, the washers can be placed over smooth unshouldered pins for positioning in the resilient material in the mold whereas if the shoulders 9 are not employed like in prior structures the pins must be shouldered to support the washers deep in the mold and the washers are therefore more likely to be upset and ineifectively positioned than by the use of my invention wherein the shoulders take the place of the shoulders on the pins and do not haye objectionable openings. in the finished product.

The body of with columns 7 in the cav1ty 3, which project upwardly and press tightly against the surface 16 which may be of the heel portion or lift upon which the heel is mounted. These columns impressing themselves against the surface 16 of the heel sustain the load in spots or zones, and in turn producea plurality of friction zones on the lower or wear the resilient heel is formedsurface of the heel body to prevent slipping. When desired a single column 17, (see Fig.

9) can be employed instead of a plurality,

the same result being accomplished thereby to a more limited extent.

In fastening my improved heel on a shoe the nails or other fastening devices employed are driven from the wear surface side of the heel through the body, a nail being placed with its point in each of the indentures 13 of the-spotters and driven directly through the heel and the corresponding washer into the heel portion2 or lift of the shoe as the case may be. After the nails have been driven home, the resilient heel is held tightly compressed upon the shoe. The nails are driven home either by hand or machine, and when the driving devices are withdrawn from the body of the heel the openings made by the nails close and seal automatically, thereby preventing any moisture or dirt accumulating in the heel and conditions.

The washers 5 prevent the nails working through the lift and into the shoe after they have been driven into the heel part and lift. The apex ends of the washers also press against the surface of the heel part or lift as the case tearing the washers loose heel.

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which. I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applie to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

'1. A heel construction comprising an elastic body to be secure' upon a shoe surface and a washer embedded therein, said body having a frusto-conical protuberance upon its surface correspon in said Washer, whereby a through said protuberance will enter said washer.

2. A heel construction, comprising, an elastic unperforated body, a washer invisible from the tread surface placed therein and a marker. arranged on the lower surface 0 the heel remote from but indicating the position of the opening in said washer, whereby a fastener'driven through said body at a position indicated by said marker will enter said opening in said washer and the opening made by sa'd fastener in' entering said body will close after the fastener.

3. A heel construction, comprising, an elastic body, and a washer embedded therefrom the rubber ding with the openingproducing unsanitary may be and prevent the nails from is driven through said Washer into said support, the outstanding stop of said Washer Will press against said sup ort. 10

In testimony whereof I have signed my name to this specification.

FRANCIS A. NOLAN.
