SHOE HEEL.

l i Application filed April 20,

T 0 all 207mm it mag concern:

Be it known. that I, LANGDON S. BARRON, a citizen of the United; States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Shoe Heels, of which. the. following is a specification. 7

My, invention has relation to improvements in shoe-heels, more particularly to the fastening devices whereby theheel is se cured to the shoe, andconsists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

Heretofore, so far as I am aware, heels (both metallic and non-metallic) have been secured to the shoe by a plurality of nails, which are cast into the metal heels, or by screws. .t is the object of the present invention to dispensewith nailsand screws as fastening means, and substitute therefor suitable cooperating" devices on the heel and shoe that may be pressed into engagementand effectivelvlock the heel to the shoe. A further object isito provide complementary fastening devices on the heel and the shoe that operate by wedging action, one member being expanded Within the other. Further and other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings in which F igure 1 is a side elevation of a shoe with my improved heel applied. parts being broken away; Fin. 2 is a middle vertical section through the heel: Fig. 3 is a front elevation of the heel; Fig". 4 is a top plan of the same; Fig. 5 is a bottom plan of the heel plate; Fig. 6 is an enlarged section through the fastening devices on the heel and the plate; Figures 7 and 8 are middle vertical section and top plans respectively of a heel provided with a modified form of fastening devices; Figs. 9 and 10 show a still further modified form of the fastening; device of the shoe, said device being fixed to a washer; Fig. 11 is a plan view of a reinforcing; strip with the fastening devices secured thereto instead of being on'a separate plate.

Referring: to the drawings. and for the present to Figures 1 to 6 inclusive, S represents a ladies shoe having an outsole 1, insole 2. metallic stiffening strip 8, and heel H, preferably of aluminum. The heel is cast hollow and is provided with a lift L old in the art.

secured against the lower face of the bottom wall 1-. The parts thus far described are However, the heel must be securely fastened to the heel seat of the shoe and it is tothis fastening means that my invention is directed. Projecting upwardly from the inside of the heel shell are a series (in the present case three) of bosses 5. preferablycast integral with the heel, although they. could be otherwise secured; and in the case of a wood or leather heel theywould have to be individual members secured to the heel in any desirable manner. The bosses 5 are substantially cylindrical and each is provided with an annular recess 6 the wall a of which is upwardly inclined. The formation ofthe recess 6 leaves a conical wedge 7 projecting upwardly at the cen ter of the boss 5. The bosses 5 constitute the fastening members on the heel. Complementary fastening members are provided on the shoe as follows: i

A metallic plate 8is inserted in the shoe sole between'the stifi'eninp; strip 3 andinner sole 2, said plate being provided witha series of bosses 9 projecting downwardly through openings 10 in the outer sole 1. The bosses 9 are provided with longitudinal kerfs 11, disposed at right angles to each other, thereby dividing the boss into four finogers 12.

In securing the heel to the shoe it is merely necessary to clamp the heel in a vise and position the bosses 9 over the bosses 5, whereupon the proper amount of pressure exerted within the heel of the shoe will force the bosses 9 into the recesses 6. As soon as the boss 9 begins to enter the recess 6 the wedge 7 will enter at the intersection of the kerfs 1.1 and spread apart the fingers 12. The fingers will be spread the whole while they are entering the recess 6, the wedge 7 maintaining said fingers in contact with the wall a of the recess. From the above it is apparent that the bosses 9 are tightly wedged into the recesses 6 and the heel is securely fastened to the shoe. Of course, the depth of the kerfs 11 and recess 6 should be such that the upper edge e of the heel will fit snugly against the heel seat of the shoe before the fingers 12 strike the bottom of the recesses 6. In practice sufficient allowance should be made so that there will al ways be some clearance between the fingers and the bottom of the recesses.

I the latter is. securely held in a vice where upon a single blow with a hammer is sufficient to wedge the boss 14: into the recess 15.

While the preferred form of fastening devices is as shown in Figures 1 to 6 still I may modify the shape of the bosses as shown in Figures 7 and 8. Here Ishow three bosses 9" projecting from the heel instead of the shoe-while the bosses 5' are on the shoe. The bosses 9 and 5 are rectangular and Qhas but two fingers 12 and bosses 5 have'complementary recesses 6 separated by a flat wedge 7. Instead of the bosses 9 being secured to a plate of the size of the heel seat I may secure them to washers or disks 1? to be placed in the shoe as shown inFigures 9 and 10, or I may secure them directly to the reinforcing strip 3 as shown in Fig. 11.

Obviously a great number of modifications might be devised that would fall with in the spirit of my invention, and I do not wish to be restricted to the particular forms shown herein.

Ha-ving described my invention, I claim:

1. A hollow shoe-heel having a boss projecting upwardly from the inner surface thereof, said boss being provided with a recess and a wedge, and a boss projecting downwardly from the heel seat of the shoe, the last mentioned boss being kerfed so as to divide it ,into a series of fingers, said wedge operating to bind the fingers into the recess on forcing the bosses into engagement thereby securing the heel to the shoe.

2. In combination with a shoe and heel therefor, a set of securing devices formed in the upper surface of the shoe heel, and a set of complementary securing devices projecting downwardly from the heel seat of the shoe, one of said'setsof securing devices beingprovided with recesses having inclined walls, the other set having fingers with parallel sides adapted to be wedged intothe? aforesaid recesses, for securing the heel to the shoe. 7

3; In combination with a shoe and heel therefor, a securing device formed in the upper surface of the shoe" heel, and a com plementary securing device projecting down wardly frointhe'heel seat of the shoe, one of said securing devices being provided with a recess having inclined walls and a conical LANGDON s.
