ELIAS J. EMERY, 01E PORTSMOUTH, NJEW HAMPSHIRE.

To all witom it may concern:

Be it known that l, ELIAS-J. EMDERY, a citizen of the United States, residing at Portsmouth, in the county of Rockingham and State of New'Hampshire, have invented Fit new and useful. Improvements in Rubber Heels, of which the following is a specifioation.

This invention relates to rubber heels, and embodies certain new and useful improvements in the type of heel disclosed in my former application, allowed August 26, 1915 and bearing the Serial Number 2,725.

In the construction of the heel covered by my application hereinabove referred'to,

useis made of reversible plugs constituting the wearing surfaoeflof the heel, and which plugs are individually and detachably associated therewith, while my latest improvements embody a wearing surface consisting of plugs adapted to be permanently fired to the body of the heel, and wherein two or more plugs as a unit can be quickly and easily associated therewith in a manner to prevent lateral movement of the plugs with relation to the body of the heel.

The nature and advantages of the invention will be better understood when the following description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

Tn the drawing forming part of this specification like numerals of reference indicate similar parts throughout the several views and. wherein Figure 1 is a view showing my improved heel fastened to a shoe. Fig. 2 is a top plan view of the heel. Fig. 3 is a sectional view therethrough taken on line 33 of Fig. 2.

Fig. 4 is a bottom plan view. Fig. 5 is a sectional view taken on line 55 of Fig. 4.

Fig. 6 is an enlarged detail View of a double plug. Fig. 7 is a bottom plan view of the modified form of heel.

Before entering into a detail description of what is herein shown, I desire to have it understood that do not limit myself to this precise construction, as various changes may be resorted to when desired as fall within the scope of the appended claims. Referring more particularly to the drawing 10 indicates the body portion of the heel, which may be constructed from any suitable resilient material preferably rubber, and of any desired dimensions. The upper Specification of Letters Patent.

Application filed December 1, 1915. Serial No. 6t,522.

surface of the heel, or that side which is arranged adjacent the upper ofthe shoe when the heel is secured to the latter, is cut away to provide an enlarged recess or pocket 11, the vertical wall 12 of which is scalloped around two sides and one end in any suitable manner, preferably in a manner to provide segments of a circle such as indicated at 13. The bottom 14 of the heel is provided with a plurality of. recesses 15, each of which communicates with the pocket 11 by way of a restricted bore 16, to permit the plugs constituting the tread surface of the heel to be easily and quickly associated with the body portion 10 in the manner to be presently' described. As hereinabove stated these plugs can be individually associated with the heel 10,- or two or more plugs as a unit, such as shown in Fig. 6 may be united with the body portion 10. A single plug consists of relatively large end portions 17 and 18 respectively, which are connected by a reduced shank 19, the plugs being constructed-from any suitable resilient material, preferably rubber possessing a high degree of resiliency. The plugs are associated with the body portion 10 by insertlng the end 17 into the pocket 11 from the underside of the heel through the restricted bore 16, the said end being of such dimensions as to snugly fit within one of the segments 13, and lie flush with the upper surface of the heel. The lower end 18 is preferably beveled as at 20, and during the operation of associating the plug with the body portion 10 in the'manner hereina-bove stated, the lower end 18 is partiallyfitted within one of the recesses 15 the walls of the latter being correspondlngly beveled with respect to the beveled portion 20, which construction together with the manner in which the end 17 is connected with the heel, eliminates all lateralrmovement of the plug with respect ,tothe body portion 10. It is of course to be understood that the end portions 17 and 18 respectively may be of any cross sectional configuration, to accommodate themselves to the particular formation of the recesses in the heel 10 which receive the same. However as shown in Fig. 6 ll propose to manufacture two or more plugs as a unit, in which instance the attaching end portions 21 of the respective plugs are connected by means of reduced shanks 22 to a single tread portion 23. The ends 21 are adapted to be inserted within the pocket 11 from the under side of the heel in the same manner hereinabove described in connection with a single plug, and snugly fitted within the proper segments 13 formed in the wall 12 as shown, while the tread portion 23 is adapted to be received within -a suitable recess formed in the bottom of the body portion 10. The tread portion 23 is preferably beveled as at.24, as is also the wall of the recess in which the tread portion 23 is partially fitted.

Obviously a single heel may be provided with a' number of single plugs and also a plug constructed in the manner shown in Fig. 6, that is to say a single tread having two or more plugs integrally connected in the manufacture of the article. Subsequent to the insertion of the plugs within the body portion 10, the heel in its entirety may. be secured to the shoe in any suitable manner, such as for instance by means of the fastening elements 25. It is of course to be understood that the duplex plug such as disclosed in Fig. 6 can be detached when worn and a new one inserted in lieu thereof. The plugs provide a plurality of independent gripping surfaces for the ground, and collectively produce a' non-slip heel. The combined elasticity of both the-heel 10 and the plug produces a heel of the-character disclosed which possesses a high degree of resiliency and maximum efiiciency.

It is believed that from the foregoing description the nature and advantages of the invention will be apparent without requiring a more extended explanation, it being understood that any number of plugs may be employed as found necessary or desirable.

What is claimed is e '1. As a new article of manufacture, a heel comprising a body having a recess on one side, and aplurality of undercut recesses on the opposite side, said recesses being comthe plug and head respectively and arranged in one of said openings.

2. As a new article of manufacture, a heel comprising a body having a recess on one side, and a plurality of undercut recesses on the opposite side, the walls of said recesses being beveled, said recesses being communicative by openings through the body of the heel, one of said recesses communicating with more than one of the openings, a plug fitted in one of said undercut recesses on one side of the heel and including a head fitted in said recess on the opposite side of the heel, and having a portion spaced from the walls thereof to permit of its expansion within said recess, and anintegral stem connecting the plug and head respectively and arranged in one of said openings.

p 3. As a new article of manufacture, a heel comprising a body having a recess on one side, and-a plurality of undercut recesses on the opposite side, said recesses being communicative by openings through the body of the heel, one of said recesses communicating with more than one of the openings, the wall of the first mentioned recess being formed with spaced depressions, a plug fitted in one of said undercut recesses on one side of the heel and including a head arranged in the recess on the opposite side of the heel and fitted in one of said depressions, and an integral stem connecting the plug and head respectively and arranged on one of said openings.

In testimony whereof I aflix my signature in presence of two witnesses.

ELIAS J. EMERY.
