SOLE FOR TURNED SHOES Filed June 20, 1950 r f /f 2f w j il /4 wf Zawya fa/725i 7 @Wm @W7 Patented Oct. 4, 1932 CLAUDE E. ADAMS, OF SEABROOK, NEW HAMPSHIRE SOLE FOR TURNED SHOES Application filed June 20,

The object of this invention is to provide a turned shoe of improved construction adaptedto be united to the upper by a continuous line of stitches made by a turn shoe stitcher, the inner or foot-supporting surface of the sole being practically uninterrupted and coextensive with its outer surface and formed in part by a flap integral with the sole, said flap covering the rear portion of the sole and the stitching uniting said portion to the upper, and covering also a shank stihener interposed between the rear portion of the sole and the flap.

A shoe having a sole embodying the invention is characterized by extreme fleribil ity, the sole and flap being made in one piece, and so joined together that all parts of the sole have a desirable degree of flexibility.

Of the accompanying drawing forming a part of this specification,-

Figure 1 is a perspective view showing the sole as originally made.

Figure 2 is a view similar to a portion of Figure 1 showing the sole conditioned to merge together the inner surfaces of the fore and rear portions thereof.

Figure 3 is a perspective view showing the completed sole, the flap being displaced to permit the channeling and shouldering of the rear portion of the sole.

Figure 4 is a sectional view showing the sole temporarily attached to a last and an upper lasted inside out and united to the sole by turn-shoe stitches, the flap being displaced.

Figure 5 is a sectional view of the coinpleted shoe showing the flap positioned to cover the rear portion of the sole and a shank stiffener interposed between said rear portion and the flap.

ner than the portion 13 and constituting a flexible flap.

i The flap 14 includes a portion of the flesh side of the sole when the latter is made. of sole leather, the flap being coeXtensive with the rear portion and oined to the fore portion by sole substance at 15 constituting a hinge.

The flap 14 is cut away at opposite ends` of said hinge as indicated at 16, 16, so that the hinge is reduced in length, its ends being oli'- set inwardly from opposite edges of the sole. rlhe cut-away portions of the flap expose limited areas of the inner surface of the rear portion 13. Limited areas of the inner surface of the fore portion 12 are skived as in-v dicated in Figure 2 by the shaded portions 17 to merge the inner surface of the fore portion into the inner surface of the rear portion, so

that the fore and rear portions have a praci tically continuous inner surface extending across both ends of the hinge portion 15.

The inner surfaces of the fore portion 12 and lower rear portion 13 are next provided, by a turn channeler, with a continuous channel 18 and a continuous shoulder 19, the flap 14 being displaced as shown by Figure 3, while the channel and shoulder are being formed on the rear portion 13, and restored to its original position while the channel and shoulder are being formed on the fore portion 12, so that in the completed sole said channel and shoulder extend entirely around the margin of thesole, and entirely surround the hinge portion 15.

rlhe sole is next temporarily secured as by tacks 20 to a last 21, and an upper 22, turned inside out, is lasted, and united to the fore and rear portions of tie sole by a turn-shoe stitch machine, forming stitches 23 entending through the between substance intermediate the channel and shoulder.

The tacks 2O are then removed, and the shoe is removed from the last and turned right side out. A shank stiffener is then placed upon the inner surface of the rear portion of the sole, said vstiffener preferably including a sheet metal lportion 24 and a nonmetallic 'portion 25 (Figure 6), the flap 14 being displaced.

Finally the flap is laid on the rear portion ot the sole and cemented thereto and to the stiliener portion 25. The flap, integrally united to the tore portion l2 by the hinge l5, constitutes t ie entire rear portion of the tootsupporting surface of the shoe, the fore portion of said surface being provided by the fore portion l2. The tlap therefore prevents injury to the heel of the wearers toot by nails attaching tA e shoe heel 27 to the heel portion of thesole. v Y i It desired, a thin soclr lining may be secured to the fore portion and flap.

lt will be seen that the iiap lll, formed by spli ting the sole from the heel end to the ball portion, is firmly secured to the fore portion l2 by the sole substance at l5, and that the rear portion of the sole including; the heel and shanlr portions, the shank stiflener, and the flap cementec to said rear portion and stiilener, constitute a rigid built-in arch support not Liable to depart from its predetermined form.

The flap lll is of uniform thinness and ilexibility from its heel end to its junction with the fore portion l2, sothat the flap does not impair the flexibility of the sole at the junction of the fore portion and flap.

I claim l.. A one-piece turn shoe sole split from its heel end through its shank portion, the split extending to a solid fore portion, so that the sole includes a fore portion of maximum thickness, a lower rear portion of lesser thiclrness, and an upper rear portion, thinner than the lower rear portion and constituting a flexible fiap adapted to cover the rear portion and stillener superposed thereon, the upper 'lace of he fore and body portions having a Continuous stitch supporting shoulder and a continuous stitch receiving, channel permitting` the attachment ot the solo to an upper by turn shoe stitches, the iiap being oined to the fore portion by an integral hinge composed of fore portion substance, said ilap being cut away to permit portions of said shoulder and channel to extend across the ends of the hi nge, the flap beingv of uniform thinness and flexibility from its heel end to its junction with the fore portion, so that the Hap does not impair the flexibility of the sole at the junction of the fore portion and flap.

2. A turn shoe having a tongue split from the inner side of the sole, said tongue being extended trein the heel end thereof to a point in the ball portion in front of the shank part and entirely across the sole throughout the heel and shank part and having its edges diverged from the Correspendingv adjacent edge portion of the sole at the front end of the shank part to the connected end of the tongue, thereby forming correspondingly diverging shoulders, and the shoe upper being connected to the sole by stitches laid in a channel which opens to the surface from which said tongue was split and to the inner surface of the forepart and extends through said shoulders, and a stiener corresponding in shape to that of the heel and shank part of the sole and secured to the sole on said surface from which the tongue was split, said tongue being adhesively connected to the top surface of said stiffener and to the sole surface in rontthereol from which the tongue was split.

ln testimony whereof l have aliixed my signature. f
