SHOE SOLE.

Application filed May 5, 1925. SeralNo. 28,191.

This invention relates to shoe manufacture andhas `particular reference to anim provement in :anxinsole for stitch-down slioes,naiiiely, a shoe structure in which the edge of the upper is turned outwardly and secured to the outer sole.

At/the present time it is the general prac- 1i tice in the manufacture of stitch-down shoes to employ a combined insole and Y middle sole by cutting a strip of leather to pro vide the. saine with a main body formed withv a vrelatively thin marginal .flange or I :welt portion projecting outwardly from and the lining into the slit entails a considerable of the body so as to 'surface of complementary vpermitting upon flexing a separationv of the'` a shoe sole structure which is comparativelyV simple, inexpensive and highly eflicient in extending completely around the shank and .iforepart at the lower portion thereof. The

body. 'is slitted inwardly from its edge in. line with the, upper face of' the flange or welt portion to receive the lower edge of the lining which is worked into the slit vand secured preferably by cement. It is obvious that the working of the edge ofv 'amount of time and labor, precludes a smooth finish and is a generally tedious operation.

fIt is therefore `one of the outstanding objects ofA theV present invention to over` vcome the above recited difficulty by dis-v posing the slit in these combined insoles andVv middle soles at anangle and extending the 'same completely-through the lower surface produce an integral flange` or welt portion provided with an un-V l derlying integral 4rand portion having a skived upper edge,

skivedk marginal portion 'confronting sk'ved faces of the body and rand portion to facilitatejthe placing and securement of the edge of the lining there Qbetween. i Y

The invention furthermore comprehends its purpose. y

' With the Vabove recited and other objects in view, reference is had to the following specification and drawings in which thoreis exhibited one example or embodiment of ythe invention which is in no way intended as alirnitation upon the scope of the apvpedient.

marginal i intersect the Vintegral randv portion the .confronting under the body of the sole having a,A

Fig. 3 is a cross sectional view of the improved sole in applied position iii .acorn pleted shoe. n Referringto the drawings by characters of reference theiinproved sole constituting `the present invention comprises a body 10 formed with an integral relatively thin niarginal flange or welt portion 11 projecting outwardly fromV the lower portion :thereof r and extending around theY shank and forepart thereof. Froinfa point adjacent to vor slightly spaced from the .rear endsof the "aration of the body and flange or welt portion and rand as illustrated in Fig. 1. In

Amanufacturing' a shoe7 the lining A of the upper B has its edges C turned inwardly andl secured preferably by -ceinenting between the complementary

skived edges

14 and 15 whil-ethe free edge D of the upper K is turned outwardly and Secured by stapling stitches orI other means vE to the flange or vThe outsole F is applied to the under side of the body 10 and a mock welt G may if desired be applied over thel outturned edges D of th-e upper after which Athe said mock welt G, outturned edge yD found exof the upper, flange or we-lt portion 11 and outsole F are stitched together by the stitching H. By separating the

skived edges

14 and 15 of the rand and body 10 of the sole, it is obvious that the operation of inserting and securing the lining edges C therebe tween is greatly facilitated, admits of a smoother finish and at the same time minim izes the time and labor required for such operation.

From the foregoing it is obvious'that the following are among the many advantages vderived from the construction, namely: (l)

the integrally connected or permanent] united insole and combined rand and we t facilitates the proper registration and relation of said parts during the process of handling and in the use of them in the making of a shoe; (2) the combined rand and welt will, due to its integral construction, be of a size required by tie size of the `insole and outsole with which it is used and of which it forms an integral part, thus obviating the necessity of selecting from a large number of separately formed rands and welts, a particular size to fit a particular sole; (3) the formation of the rand, welt and insole integral permits the production by a single cutting operation of the under side bevel about the margin of the shank and forepart of the insole .and the corresponding bevel of the rand projecting beneath the sole, thus producing mating, complementary beveled surfaces between which the lining is secured.

It is, of course, to be understood that the blank from which the insole is made, is

formed exactly to the size of the heel at its rear portion to produce a heel seat and that it is laterally enlarged from a. point corresponding to the front of the heel, along v the shank and about the forepart to produce the projecting welt portion or flange. Thereafter the edge of the projecting portion is slit inwardly parallel to the upper and under surfaces about the shank and forepart upon a line correspondingto the marginal edgeof the shank and forepart of the insole and that the upper part of this extension formed by slitting is removed by a cut substantially triangular to the surface,y thus forming a shoulder defining the shank and forepart of the insole rand that part extending beyond the shoulder which constitutes the welt. Thereafter the rand portion is formed by a. cut which extend-s inwardly at an angle from the base of this shoulder to the under surface producing both the under beveled marginal edge of the insole and the upper beveled edge of the rand portion of the welt or fiange.

kI claim: l. An insole for stitch-down shoe structures, comprising a body including a heel portion, a shank and forepart, an integral outwardly projecting welt secured to the opposite sides of the shank adjacent its juncture with the front of the heel portion and extending around the shank and forepart and a rand extending inwardly from and' formed integral with the welt to normally underlie the marginal portion of the shank and forepart.

2. An insole for stitch-down shoe structures, comprising a body including a heel portion, a shank and forepart, an integral outwardly projectingwelt secured to the opposite sides of the shank adjacent its junctionv with the front of the heel portion and extending around the shank and forepart and a rand extending inwardly from and formed integral with the welt to normally underlie the marginal portion of the shank and forepart, the said marginal portion of the shank and forepart and confronting face of `the rand being complementarily skived.

3. An insole for shoes comprising a body member having a reduced outwardly projecting flange or rand from the lower portion of the marginal edge of the 'shank and forepart, the 'said body being slitted inwardly and downwardly from its juncture with the flange or rand from a point adjacent the rear edges of the rand to provide complementary lskived faces permitting of relative separation.

4. A stitch-down shoe, comprising an insole and a combined rand and welt formed integrally and permanently connected at a point approximating the front of the heel seat, the combined rand and welt extending along the shank and about the forepart, with the rand portion extending beneath the marginal edge of the 'shank and forepart of the insole, the whole formedof a single piece of leather, the opposed surfaces of the insole and rand beveled by an inclined cut extending from the edge of the insole to a point within the edge and emerging from the undersurface thereof, a lining turned inwardly and secured between the opposed beveled surfaces of the insole and rand, an upper having its edge turned outwardly upon the upper surface of the welt, means for fastening the upper to the welt on a line closely adjacent the edge of the insole, and an outsole secured to the outstanding welt portion of the combined rand and welt.

5. A combined insole, rand and welt, having a projecting edge forming the welt along the shank and about the forepart from a point approximating the front of the heel seat and formed integrally of a single piece of leather, and a rand portion extending inwardly from the edge of the insole beneath the under surface thereof, the insole and rand having opposed complementary beveled surfaces.

5 from the juncture of the upper 6. In a shoe, an inner sole consisting of a body formed with a marginal projecting 'flange extending around the shank and forepart at tlie lower portion thereof and slitted face of the iange transversely inward and downward through the bottoni to permit of relative separation of the flange and body for Jfacilitating the insertion and `securenient of tlie lining therebetween, the iange constituting ineans for securing the upper to the insole and means for attaching the Welt and outsole to the insole and upper.
