SHOE.

Application filed Ju1y 25,.1922. Serial No. 577,272.

To all. whom it may concern:

Be it known I, Gnonen C.-VAUGHAN, a citizen of the United States, residing at Hamilton, county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Shoes, of which the following is a specification, reference being had therein to the accompanying drawings.

As is well understood by those skilled in the boot and shoe making art, McKay shoes are ordinarily very stiff and inflexible due to the fact that the parts of which the sole is compbsed act like a truss and prevent flexing of shoes. This fact will be understood when it is considered that in bending the shoe transversely, as occurs in walking, the lower surface of the outsole is stretched while the insole, particularly at its upper or inner surface, is compressed. This stretching and compression of the two layers composing the sole isstrongly resisted by the materials if the shoe is'well made so that the sole as a whole is very stifil. However, if the sole as a whole bends, the compression of the insole causes it to buckle and form transverse wrinkles under the ball of the foot where the weight is chiefly supported. This has been found to be a serious objection to McKay boots and shoes.

The present invention has for its objecta boot or shoe which will be flexible across the ball'of the foot and therefore will be more comfortable and durable; While my invention is particularly applicable to Me- Kay shoes, I do not limit myself to its use in shoes of this type.

The invention will be fully understood from the following description when taken in connection with the accompanying draw,-

pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Fig. 1 is a longitudinal section of the shoe embodying my invention.

, Fig. 2 is an interior view of the shoe shown in Figure 1, the parts of the upper being separated to disclose the construction of the insole.

Fig. 3 is a view similar to Figure 1, but showing the-action of the parts when the sole is bent.

Fig. 4 shows a modification of my invention.

Referring now to the drawings, particularly Figures 1 and 2, at A is shown the outsole, at B the insole, at C the upper,

mgs, and the novel features thereof will beand a 1) the stitchiri g by means ofwhich the outsole and insole are secured together.

In practising my invention in its preferred of the rear of the ball of the foot of the wearer of the shoe. In other words the slot 'F is inclined transversely, the end of said slot which is nearest the inside foot part of f the sole being nearer the toe part of the sole than the other end of said slot. Intercept-- ing the ends of the slot F, are two side or wing slots G and H. These slots may be curved, as shown in Figure 2, i'n which case they are substantially parallel with the line of stitching D by which the parts of the shoe are held together, or they may be given such other shape and direction as seems necessary. I

These slots F, G and H together form a tongue K. This tongue K is not cemented, stuck, nailed or otherwise secured to the outsole, although it is still an integral part of the insole. The tongue is therefore free to slide relatively to the outsole. The inclined arrangement ofthe slot F above described results in an even sliding movement of the tongue K when the wearer of the shoe is walking.

From the foregoing it will be seen that when the sole of the shoe is bent along the line of the slot F, the tongue K can slide slightly on the outsole, thereby narrowing the slot F, the unsevered portions L and M of the insole opposite the ends of the slot F, serving as hinges to connect the toe and heel portions of the insole and materially strengthen the shoe. The slot in the insole permits the outsole to bend easily without compressing the insole and there fore greatly increases the freedom of movement of the parts and the flexibility of the shoe.

In Figure 4 is shown an insole provided with slidable tongues of different forms.

This insole contains two zigzag slots S and T forming tongues U, V, W, X, Y', and Z. This construction gives more extended flexibility than a hinge at the line of the ball and may be more satisfactory for certain classes of shoes.

What I claim is:

1. An improved shoe having an outsole and an insole secured together, the insole being slotted transversely at a point about midway of its length, so as to come in proximity to the rear part of the ball of the foot of the wearer, a narrow piece of stock being removed from said slot and the ends of the slot terminating closely adjacent to, but short of the side seams of the shoe, said insole having other slots at an angle to the first-mentioned slot and which are disposed closely adjacent to and parallel to the'lines.

of stitching at the sides of the shoe, thus forming a tongue which is adapted to move relatively to the remainder of the insole when the shoe is bent, the parts of the insole outside of said tongue and last-named slots affording hin econnections between therear and forwar parts of said insole.

2. An improved shoe-having an outsole and an insole secured-together, the insole being slotted transversely at .a point about midway of its length, so as to come in proximity to the rear part of the ball "of the a foot of the wearer, said slot being inclined transversely so that the end'thereof which is nearest the inside foot part of the shoe is nearer the toe part of the shoe' than the other end of" said slot, a narrow piece of stock being removed from said slot and the disposed closely adjacent to and .of the insole outside of said tongue and last-named slots affording hinge connections between the rear and forward parts of said insole.

3. An insole, for-boots or shoes, having a cut-out transverse slot about midwa of its length" at-a point: in proximity to t e rear part of the foot ball rtion of said insole, said slot being inclin end thereof whicl'ris nearest the inside'foot portion of said insole being nearer the toe part of said insole than the other end of said slot, said .insole having other slots communicat'mg withjandr extending forward from said first-named-slot, thus forming. a loose tongue having-a transversely inclined rear end.

In testimony whereof 1am: in .si ature. GEORGE GQ'VA G AN.
