RUBBER HEEL.

Application filed October 19, 1926. Serial No. 142,663.

This invention relates to an improved rubber heel ofthe separable or detachable t e. v

y riefly, the invention'- has reference to a leather lift and a'rubber lift fastened to the leather lift, the rubber lift being composed of main and supplemental sections, and there being novel means between the sections for permitting replacement and removal of the supplemental" section, which, as is obvious, is-the section which is subjected to the greatest wear. 7

My principal aim is to generally improve upon structures of this class by rovidmg one of comparative simplicity an durability wherein the parts are novel and are associated in such, a we as to render the structure practical and c 'aracteristic.

An important feature of the construction is the means for connecting the two sections of the rubber heel together, this embodying a lotted plate carried by one section, and a complemental plate carried by the other section and having headed studs for rece tion in the slots in the first named plate, w ereby to provide a readily separable connection between the two sections of the heel.

Other features and advantages will become apparent from the follow ng description and drawing. a

In the accompanying drawing forming a "part of this application and in which like numerals are em loyed to designate like parts throughoutt e same Figure 1 is a bottom plan view of a heel constructed in accordance with the inven tion.

Figure 2 is a side view of the same.

Figure 3 is a section taken approximate ly upon the plane of the line 3-3 of Figure 2. s

Figure 4 is a transverse .cross section taken approximately upon the-plane of the line 4-4 of Figure l.

Figure 5 is a top plan view of the removable supplemental section of. the. rubber lift, and- Figure 6 is an inside endview of the same.

Referring to the drawing in detail, it will be seen that the reference character 1 designates the leather ly or liftwhich is adapted to be secured to t 0 shoe in any appropriate manner. The rubber lift is generally designated by the reference character 2 and as is fastened by, nails or the like 11.

anchoring plate 10.

before indicated comprises a main section 3 and a supplemental section 4. The main section is of an outline corresponding to the leather ply, and the latter is of the usual outline. It will be noted, however, that substantially one-half of the rear portion of the main section is cut away to provide a shoulder 5 which is inclined as shown in Figure 3 and which forms a relatively thin portion 6. The supplemental removable rubber section 4 is of a shape to fit accu-. rately into the cut away area represented in Figure 3. Moreover, as shown in Figure 6 this section is bowed transversely to render it of cupped formation. In additon, it is provided on its inner side with a recess 7 in which a metal plate 8 is secured. This plate carries a pair of headed studs 9. The

studs are proportioned in length with respect to the depth of the recess 7 to cause the heads to project above the inner surface of the rubber as shown in Figure 6. Formed in the thin portion 6 of the main section of the rubber is a recess. to accommodate a complemental anchorin plate 10 of the configuration indicated in Figure 3. This late t is provided with a pair of elongated slots 12 at the rear ends of which are circular enlargements 13 adapted to permit) passage of the heads on the studs.

In practice, the leather ply 1 is fastened to the shoe in any convenient manner and the shouldered portion or section of the rubber lift is secured thereto as represented in the drawing. Then the portion 4 is placed in osition by inserting the heads of the stu s 9 in. the enlarged entrances 13, whereupon the shank portions of the studs are slid into'the restricted portions of the slots. In this connection it will be noted from Figure 3 that the edge portions of the slots overhang the heads and provide a firm connection between the two sections of the rubber lift. Owing to the inherent resiliency and cupped shape of the section 4 as re resented in Figure 6 it is obvious that t e tendency of the same when flattened as indicated in Figure 4, is to resume its normal concavo-convex state, and hence it exerts an outward pull upon the studs, thus binding the heads of the same firmly against the known that the entire rubber heel does not From practice it is wear equally and it is the portion repre sented by the reference character 4 which is subjected to the greatest Wear. Hence, by simply replacing this and having standardized bonnections, the expense of renewal of rubber heels will be comparatively small. Moreover, it will be possible to renew the heel without requiring the services of a skilled repair man.

It is believed that by considering the description in connection with the drawings a clear understanding of the invention will be had. Therefore, a more lengthy description is thought unnecessary.

\Vhile the preferred embodiment of the. invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described the invention. what 1 claim as new and desire to secure by Letters Patent is As a new product of manufacture, a rubber heel comprising a main section of conventional outline embodying a relatively thick portion and a relatively thin portion providing a shoulder at the juncture of said portions, said shoulder being inclined and disposed transversel across said section, a plate secured to the bottom face of said thin portion, said plate being provided with keyhole shaped slots, and said thin portion being provided with grooves in alinement with said slots, a renewable section of segmental configuration adapted to be placed against the bottom of said thin portion and to abut said shoulder, said renewable section being provided in its top with a recess, an attaching plate located in said recess and passed through said renewable section and carrying headed studs cooperable with the slots in said first named plate.

In testimony whereof I affix m signature.
