HEEL-PROTECTOR FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 354,064. dated December 7, 1886.

Application filed August 21, 1886. Serial "No. 211,555. (No model.)

To (LZZ whom it may concern.-

Be it known that l, ELEAZER KEMPsHALL, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Heel-Protectors, of which the following is a specification.

This invention relates to that class of heelprotectors which are to be inserted in the bootheel, the object being to provide a protector adapted for insertion in the heel of rubber boots, as hereinafter more fully set forth.

In the drawings accompanying and forming a part of this specification, Figure l is a plan view of the under side of the heel of a rubber boot having inserted therein a protector embodying my invention. I Fig. 2 is a side elevation, partially in section, of same. Fig. 3 is a horizontal section on line a, Fig. 2. Fig. 4 illustrates how the protector is placed in the heel-mold before the heel is pressed into shape. Fig. 5 is an enlarged plan view of the preferred form ofprotector before using. Fig. 6 is a side elevation of the same. Fig. 7 is a vertical section in line b b of Fig. 5.

Similar characters designate like parts in all the figures.

The mode of protecting heels made of leather by inserting in them metallic plugs is well known. In that case the plugs or cylindrical or conical pieces of metal are usually forced into holes made in the lower lift or layer of the heel, which lift or layer is afterward fastened into place. By this mode the protectors are readily fixed into place in leather boots; but in rubber boots the same mode is found in-' sufficient. It is desirable in the latter case to secure the regular arrangement of the protector in a heel, while it is considered necessary to place them in the heel-mold before pressing them into shape. To insure, under these conditions, the desired result is one of the objects of my present invention.

My improved heel-protector comprises a series of wear-resisting plugs, preferably three in number, made of hard cast-iron or other hard metal, the several plugs being connected by a malleable bar in such a way as to constitute a single device, and the end plugs being furnished with placingbraces, as hereinafter de- The bar 10 may be shaped to fit the dovetail recess 11, (shown in Fig. 7,) formed intheend of the plugs, 'or it may be round, as at 12 in the same figure. These wear-resisting plugs may be adjnstably secured to the bar and placed thereon at different distances apart, to accommodate the protector to a greater range of heels. The metallic connections are more shallow in a vertical direction than the plugs, so that they are covered by the rubber of the heel when the plugs are so located as to be visible on the surface of the rubber.

One part of my improvement relates to the construction of the wear-resisting plugs used in the protector, whereby the plugs are adapt ed to be set securely in the yielding substance of rubber-boot heels. This improvemeutconsists in making the plug in the form of a hollow cone, or other shape tapering toward the lower face of the heel, and in providing such plug'at or near its base with an arm, 15, which serves a double purpose-as steadyiug-bar and placing-brace. As will be seen, one of these arms 15 is provided for each terminal plug of the series.

The hollow plugs, when in place, are filled with a rubber core, 8, integral with the material of the heel, so that a much greater resistance is obtained against any sidewise displacement than would be with the plug in a separate piece from the heel.

I do not, however, limit myself to a hollow plug, as my invention is present in one of its forms when a series of plugs, either solid or hollow, is used in combination with skeleton connections between the plugs and with placing-braces upon the terminal plugs.

The arms of placing- braces 15 and 13 are formed on the plug at or near its large end, as clearly shown in Figs. 6 and 7. These arms preventthe protector from being driven against the side of the heel-mold while the heel is being formed about the protector, and they resist IOC : adjustable thereon.

any force tending to tip the plug out of its vertical position. In this respect said arm cooperates with the core in the hollow plug when the hollow plug is employed, and the connect- 5 ing-arms also co-operate in discharging the same function. These terminal placing-braces may be made upon the plugs themselves, or in the form of my protector, in which the plugs are dovetailed upon the bar, or otherwise made The placingbraces may constitute continuations of the rod, as shown in Fig. 4.. Whether thea'rms areon the plug or are upon the arms extending beyond the plug. they are so shaped and located as to be driven outward by the plastic material while under pressure in the mold. In this way the properlocation of the series of plugs is secured, while the connecting bars and arms. being securely embedded in the rubber in the finished 2o heel, co operate with the integral core within the hollow plugs in holding the heel-protector firmly and permanently.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent of the United States, is.-

1. A wearresisting plug for rubber-boot heels, consisting of a hollow frustoconical plug having an arm or placing-brace projecting laterally from the base thereof, as set forth.

2. The combination, in a heel-protector, of 0 a series of wear-resisting plugs and a malleable connecting-bar, said plugs havings openings for adjustment on said bar, substantially as described.

3. A heel-protector having a series of wearresisting plugs secured to a malleable bar connecting said plugs, in combination with arms or placing-braces, one at each end of the protector, all substantially as described.

4.. The combination, in a heel-protector, of a series of hollow plugs united by a bar extending through them, said plugs being adjustable thereon and the end ones having placingbraces at their sides, substantially as described, and for the purpose set forth.

5. A heel-protector consisting of aseries of hollow frusto conical plugs united bya malleable bar extending through a recessin the end of the plugs the plugs being adjustable on the bar and the end ones provided with an arm or placing-brace, as and for the purpose set forth.
