This invention relates to shoes and has to do particularly with a shank reenforcement.

It Vhas for its object to produce a simple, ei-

cient and practical device which will function to effectively isupport the shank portion of 1Lhe shoe sole or bottom so as to resist downward pressure thereon and yet be sufficiently yieldable in the opposite direction to give the proper flexibility and elasticity to afford comfort to the wearer in walking.

The invention-'consists in the novel construction and arrangement and-in the combinations hereinafter described and afterwards pointed out with particularity in the appended claims.

In the accompanying drawings illustrating certain practical adaptations ofthe invention and forming partV of this specification,- Y y, i

Figure 1 is a side edee view ofthe reenforcement it being shown in full lines and the heel and sole portion of the shoe being shown conventionally in dotted lines to illustrate generally its application;

Figure 2 is a top face view ofthe reenforcement detached from the shoe;

Figure 3 is an end edge view showing the general cross section of the reenforcemen'tI illustrated in Figures 1 and 2; y

Figure 4f is a top face view of a modification of the reenforcement;A

Figure 5 is an end edge view of the reen-y forcem'ent illustrated in Figure 4, showing the cross section of the end portions ofthe reenforcement;

Figure 6 is a view showing lthe cross section of the portions of the reenforcement between the middle and end portions.

Figures 7 and 8 are views showing cross sections of the middle portion of the reenforcement where the folds are made alternately from opposite sides;

Figure 9 is a plan view of an approximate formation ofthe blank from which the reenforcement illustrated in Figures 4to 8, inclusive, is constructed; and l Figures 1() to 13, inclusive, are views'V illustrating cross sections of further modifications of the reenforcement.

Referring now to the drawings, meral 1 designates generally the shank reenforcement which is preferably formed from sheet metal and possessing more or less resiliency in the character of the metal. Y

As shown in Figures 1, 2 and 3, the rethe nu- 'Y enforcement comprises a strip having a crimped or ribbed Stifte-ning portion 2 eX- tending longitudinally and medially of its upper face. `At intervals this crimped or ribbed portion is'cut crosswise, as at3, to face of the flat body portion, the severed. ribbed or stilfening portions or Segments 4 abutting when the support is in its normal set. This affords'a substantial support under the weight of the wearers foot so as to prevent breaking down of the shank of the shoe, yet it is yieldablein the opposite direction. That is to say, vthe middle portion of the support may be raised or the end portions may be moved downward.

In Figures lto 9, inclusive, a modification of the shank reenforcemcnt is shown. In this modification the reenforcement is formed from a blanksubstantially as shown in Figure 9. At about midway between its ends the blank is slitted, as at, and notched, as at 6, to afford tongues Z in alternate or staggered relation on opposite sides of the blank,`the tongues being somewhat wider than the notches so that when folded over upon the base'- portion and` betweenveach other with their edges abutting the reenforcement is given an arched shape and serve to prevent the arch from collapsing or breaking downward under the weight of the.

wearers foot as in the structure first described. To afford a more substantial support the tongues 7 are provided with raised formations 8 which constitute a vstiffening rib in 'effect when the support is in normal shape. In some cases, however, the formations 8 may be eliminated and the folded tongues 7 alone depended upon to maintain the arch. y

Between the ends of the rib formed by the portions Sand the extreme end portions of the support the marginal portions of the body are rolled, as at 9, to afford rigidity lto that portion of the reenforcement. This, however, may be eliminated in some cases.

The reenforcement may be vsecured in place in the shoe structure in any desirable manner. As shown, ity is kprovided with apertures 10 at its ends to receive rivets or other fastening devices or means. l

The device is. also subject to further modiication in cross 'section vas indicated by Figures 10 to 13, inclusive, as well as in other obvious shapes; and it admits of considerable modification in other respects without depart-ing from the spirit and scope of the severed transversely andthe segments there- 10 invention as defined b v the appended claims. It is, therefore, not limited to the specie constructions and arrangements shown in l'he drawings.

That is claimed is :v

1. In a. device of the character described, sheet-like body having u longitudinal stiffening; rib on its upper Side, said rib being,r

of normally abutting each other.

2. In a device of the character described, a n'xultiplieity of upstanding, abutting', stiiening elements arranged in longitudinal aline-- ment :rnd being; flexibly joined at their bases. whereby to resist downward pressure but })ermiting upward flexion of said device.
