Specification of Letters Patent.

' ratentea nov. 26,1907.

Application filed November 22 1906; Serial NO. 3441525;

Be it known that I, WILLIAM C. STEWART, a subject of the King of Great Britain, and a resident of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Boot and Shoe Soles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings represcnting'lil e parts. I

This invention aims to provide a novel and highly flexible or pliable sole for b'oots, shoes or other foot wear.

The nature of my invention will be best understood from a description of one embodiment thereof selected for illustration herein and illustrated in the accompanying drawing.

In this drawing; Figure 1 is a plan view of one face of an insole illustrating one embodiment of my invention; Fig. 2 a longitudinal section on the line 22, Fig. 1, showing in dotted lines a portion of theinsole bent or flexed; and Fig. 3 a transverse section on the flex or bend when in use.

line 3-3, Fig. 1, on an enlarged scale, showing in dotted lines the relation of the slitted portion of the insole to the marginal portion, when the insole is flexed.

In the particular embodiment of my invention selected for illustration herein, and shown in the drawing, the sole illustrated and marked Sis what is commonly known as a welt insole, that is, an insole adapted for use in the manufacture of what is known as a welt boot or shoe, it being understood, however, that my invention is not restricted to such a sole.

The sole illustrated is rovided with a marginal shoulder 5 fol owing approximatel the outline of the sole and, within said s ioulder a shoe channel 6 to receive the welt or inseam stitches that secure the upper or welt to the insole. Within the channel 6 and, in the vicinity of the fore part or ball portion of the sole the latter is shown rovided with a series of transverse sits, slashes, or incisions 7 shown as oblique (see Fig. 2) and extending from one surface of the sole through nearly to the opposite surface thereof, leavin an unslitted portion of rela-' tively slight t ckness such as will readily I Preferably the oblique slits will overlap each other slightly,

as shown, thereby to reduce the thicknessof the intervening portions. The slits preferably open toward the heel end of the sole although excellent results may be had where they 0 en op ositely or toward the toe. I have ound, owever, that the transverse slits or incisions are much less eiiective 1n flexing thesole if the intervening portions near the endsthereof are permitted to remain oined integrally to the marginal or un- A gitudinal slits 0r incisions in the sole shown is to leave the sole portions lying between the transverse slits free to throw outwardly as indicated in dotted lines Fig. 2, when the sole is flexed or bent in use, thereby giving to the sole the greatest flexibility or pliability possible to be derived from the transverse slits unrestrained by any tying or uniting of the intervening portions with the unslitted marginal portions of the sole. Inthe sole shown these longitudinal slits or incisions extend at their bottoms also oblirl uely downward following in this respect't 1e planes of" the transvcrseslits formin substantially,

tongue or partially separate portions 9, the effect being that the entire portion of .the

sole'lying above each transverse slit, is leftfree'or separated at its ends from-the marginal ortion of the sole.

Or inarily it is suilicient to provide the intersecting or longitudinal slits or incisions at the ends only of the transverse slits, but,- if desired, the said'intervening sole: portions may be longitudinally slit at other points between their ends, as, .for instance, as indicatedatlO. l

I have rciierred to the flexibilit T of the sole being secured by. slitting or slas ing it, but obviously my invention contemplates any method of providing the sole with lines or planes of weakness/as defined in the claims Whether by slitting, slashing, scoring or other- Wise to produce the desired effect.

' WVhile it is convenient to arrange thetransverse and longitudinal slits as here indicated, yet obviously the directions thereofmay be changed relatively or otherwise as desired without detracting or departing from my invention.

Having described my invention by means of one embodiment thereof as an illustration of the same What I'clairn in addition thereto and desire to secure byLetters Patent of the United States is 1. Asole for boots and shoes provided with a series of substantially transverse incisions extending inwardly obliquely to one surface stantiallv transverse incisions of less length than the width of the sole, and longitudinal incisions disposed in planes intersecting the planes of said transverse incisions adjacent the terminal portions thereof."

. 4. A sole for boots and shoes having Sllb'. stantially transverse incisions disposed obliquely t0 the surface of the sole, a portion of one transverse incision overlapping a portion forming integral tongues.

A 6; A sole for boots and shoes characterized of another, and longitudinal incisions intersecting the transverse incisions.

5. A sole for boots and shoes characterized by substantially transverse incisions extend- 40 ingpartiallyflacross the sole forming transverse portions separated from the sole atone edge, said transverse portions each having terminal parts separated fromthe sole and by substantially itransverse incisions disposed obliquely to the surface of the sole and forming transverse portions separated from the sole at one edge, terminal partsof said'transverse portions being also, free from the 'sol-e material.

7. A sole for boots and shoes incised transversely and obliquely with relation to the surface of the sole, and incised longitudinally in planes intersecting the plane of the transverse incising and adjacent the terminal portions thereof. I

8. A sole for boots and shoes provided with a series of transversely extending inci- 6O sions disposed obliquely to the surface of the sole and opening toward the heel, and longitudinal incisions disposed in planes intersectthe planes of the transverse incisions. in testimony whereof, I have signed my name to this specification, inthe presence of .tWo subscribing Witnesses.
