HEEL RETAINING MEANS FOR SHOES Filed Dec. 2l, 1939 JNVENTOR. ouzls Jaa ATTR/VE'Y.

Patented Apr. 8, 1941 l UNlTED STATES PATENT OFFICE HEEL RETAINING MEANS FOR SHOES Louis Sabo, New York, N. Y., assigner to Delman Inc., New York, N. Y., a corporation of New York My invention relates to the art of shoemaking.

The object of my invention is to provide a shoe which is made with a wooden heel generally known as a Louis heel which is formed to provide a curved extending portion which rests under the shank of the shoe located adjacent to the heel; to add to such a construction, a brace which serves to hold said extending portion of the heel `in iirmly fixed relation with the arched shank portion of the shoe and to prevent relative movement therebetween.

A further object is to provide a shoe with a brace for the purpose stated, which will lie upon and conform to the curvature of the heel and shank at their point of juncture in such a manner as to be inconspicuous and substantially concealed from view by the usual flap portion used in cover- `ing the breast of the heel.

thin strong metal formed with corrugations which extend upwardly from the base line of the under side of the brace and are closely adjacent, to stiffen the brace in the direction of its width while permitting the brace to bend easily in a direction at a right angle thereto.

Further objects of the invention and the advantages gained by the use ofthe improved construction will be further disclosed hereinafter:

Referring to the drawing which forms a part oi the specication:

Fig. 1 is a perspective View of the side and arch portions of a shoe, and having a Louis heel thereon a portion of which is covered by a brace which extends therefrom over a portion of the shank adjacent thereto.

Fig. 2 is a plan View of a brace consisting of a thin metal plate such as hard rolled copper, formed with corrugations which extend across its width, and having apertures thru which cement may flow.

Fig. 3 is a longitudinal sectional view on lines 3--3 of Fig. 2.

Fig. 4 is a top or plan view of a brace formed without corrugations.

Fig. 5 is a longitudinal sectional view on line 5-5 of Fig. 4 showing a brace construction formed with extended apertures.

Fig. 6 isa plan view of a brace plate in which the apertures are omitted; the two holes shown being used to permit brads to pass thru in the act of attaching the brace to the shoe.

Fig. 7 is a longitudinal sectional view on line 1-1 of Fig. 6.

Fig. 8 is a perspective View of a brace in which slots are formed between the corrugations.

Fig. 9 is a View of a portion of a brace having corrugations formed by a` crimping process whereby a greater number of corrugations may be formed in a given length to increase its stiiness, and to increase the area of surface whereby the cement will serve to more rmly unite the brace with the leather or wood over which it extends.

While in most of the views I have shown the brace as extending `in a plane thruout its length, it will b-e understood that in most cases the brace will be curved to conform with the curvature of the extending portion of the heel on which it rests.

Since the use of Louis heels are well known in this art, the extending portion of the heel overlying the shank, will hereinafter be referred to as the flange.

In a former patent granted to myself and anv other, and bearing the patent No. 2,167,526, a heel retaining means is disclosed which functions well for the purpose designed, but its construction has been found to be expensive in first cost, and in time required to attach it to a shoe;l also on account of its thickness it imparts an unsightly appearance to the shank of the nished shoe.

By the use of the present construction a stronger joint is effected, and the leather flap covering the brace effectively conceals it without disclosing its .presence in the shoe.

l0 indicates a shoe having a wooden heel of the Louis type thereon which is formed to provide a curved flange Il which extends over the shank I2 in the usual manner.

lu' indicates a flap formed integral with vthe outsole of the shoe and serving to cover the fiange H and the breast of the heel Il in the usual manner.

I3 indicates a cement used in` shoemaking, which is applied to the flange ll and shank portions |2 and breast Il.

I4 indicates a brace-plate embodying my invention, which is immersed in the cement and extends over the fiange and shank of the shoe at their junction, as illustrated, pressure being applied to the brace-plate to force it into close contact with the surface thereunder while a brad is inserted in the openings l5 to assist in holding the brace-plate in position, and thereafter the flap I0 is cemented to the shank, brace-plate and heel in the usual manner.

The thickness of the brace-plates is approximately one sixty-fourth of an inch, and the corrugations are about one thirty-seconds of an inch high, and the leather of the flap is sufficiently thick and soft to encase the brace-plate and hide completely, as will be readily understood by shoemakers.

Therefore it will be understood that the drawing are made on an enlarged scaley the corrugations actually being in the form illustrated in Fig. 9 and indicated by I6, and extending entirely above the lower side I8 of the brace.

In Fig. 8, I have shown a brace having slots I8 formed in the lower side of the corrugations, thru which cement may pass to insure complete covering of all exposed surfaces in the act of cementing the parts together.

t9 indicates thin depen-ding sharp edge portions of the brace-plate which are found useful when using :a plate made as illustrated in Figures 4, and 5, which may be used Without cement if desired, the apertures I1 .being used as guides for brads which force the circular edges of the depending portions into the wood of the flange or leather oi the shank in the act of securing the brace-plate to the shoe, and prevent the brads from tearing thru the pleite under strain and also prevent any shifting of the plate relative to the flan-ge or shank `to which it is attached.

It will be `understood that the upper side of the corrugations when filled with cement, present a smooth upper surface to the under side of the leather ap I0 `and at the same time serve to impregnlate the .leather of the nap at the points of juncture with the cement, and t-hat the under '2f side of the brace-plate serves the same function in uniting the woo-d or leather `of the shank with the brace-plate.

`Having thus described my invention I claim as new:

l. Means for retaining a Louis heel on a shoe, consisting of a single base-plate of thin strong .flexible material of less length than :the Width of the shank of a` shoe to which it is to be attached and having apertures therein between its ends to serve as passages for fluid 'cement used in securing the heel t-o a shoe.

2. Means ior retaining a Louis heei on a shoe, comprising a hase-plate of thin strong material of less length than the width of the shank of a shoe to which it is to `loe yattach-ed and having a number of transversely extending corrugations formed therein to stiffen the construction.

3. The construction defined in claim 2, together with; said base-plate having apertures therein which form lpassages for fluid cement used in securing the base-plate to the heel and shank ofthe shoe.

4. Means for `retaining a Louis heel on a shoe, comprising a base-plate of thin me-tal of less length than the width of the shank of a sho-e to which it is to be attached, and having apertures therein with side wails which `depend from the under side of the base-plate.

5. In a shoe having a Louis heel ythe flange of which extends over a portion of the shank of the shoe, that improvement which consists in applying ilu-id cement to said flange and the shank Iportion adjacent thereto, -oi a base plate made of thin strong material immersed in said cement and termed with apertures which serve as passages for the -cement to now thru, said base-plate extending over a portion of said flange :and shank a't their junction, and means for covering said base-plate.

6. The construction defined in -cla-im 5, together with; said base-plate having `corrugations eX- tending transversely of the length thereof which serve to hold cement and to form a support for the base-plate covering means.

'7. In .a process for attaching a reinforcing plate to a shoe having a Louis heel the ange of which extends over a portion of the shank of `the shoe, that improvement which consists in applying fluid cement to said flange and the .shank 'portion adjacent thereto, an-d immersing a Ibase-plate made of thin strong flexible material, yof ifess length than the width thereof, in cement, and applying the same over a portion of said ange and the adjacent shank portion of the shoe, and then covering said base-plate With a sole flap.

LOUIS SABO.
