Fig. 2 'is a cross sectional'view on thelineZ--Z OfFal; f

Fig. 3 is a longitudinal sectionaliview oftheI outsole on the line 3--3 offFig. 1;

e Fig. i isa view similar to Fig. 3, showing..azmod-A iiication;

can be made in accordance with any other suit- .'ablegshoe manufacturing method, for example McKay and Goodyear welt. As the `present invention is concerned more particularly with the constructionl of thek outsoler I4, the latter will now be more vspecifically described. y

`Outsole I4.is formedof solev leather and comprises, ashereshown, the end. sections. I4a, and I4b andthe-intermediate sections I4c, Idd, and ille, all of said sections consisting ofstrips of sole leather. preferably of the thickness of the nishedoutsole, disposed Widthwise of they sole with their opposite sideedges in adjacent sideby siderelation. Eachcf said intermediate sections is provided withlcutfoutfportions at itsopposite. side edges providing at each side edgea recess I8 and av lateral `projection vor. tongue 20, extending continuously forthe full length of the section,

i. e., for thefullwidth of the shoe. vThe yend sections I4a and I4bare provided'at vtheir forward and rear-edges, respectively, withrecesses I8a' and tongues 20a. When said sections are assembled in adjacent, side. by side`.relation,'the adjacent tongues. of Vadjacent sections t in the adjacent recessesfcfy the.adjacent sections, the adjacent: tongues Ofadjacent sections overlap V'ping' each other.V The tongues 4and recesses are I preferablyfdimensioned.so that the freefed'ge 'of tonguesis equalto the full thickness` of' the in-l lFigs. 5 andy 6 areffragmentary..bottornxviews. y

upper -I2 and with aisectionaloutsole. I4 embody. I ingthe present invention. Said uppermaybesof;

' any suitable construction or style for men. women for children .and may. be formed of any suitable mater-mls. As here shown, the shoe is of a well f' known cemented construction, the 'outsole the upper and the insole I6 being adhesively secured "together, all .as well known to shoe manufac-v tuners, but it will ybeunderstood that the shoe throughsaid overlapped po tions.

termediate portion 22 ofthe section, whichv is `prefe'rably the. full 'thicknessof the outsole. I n

thisform cf'theinv'ention the forward yedge of theend section Illa is disposed substantially at' the ballv linebut itwillbe understood that the sole maybecomposed of a larger number'of the narrower rsections and. thatthe latter may be disposed intheshank andheelportions of the outsoleinstead offbeing provided,[as here shown;

only the part of the soleforwardly of lthe'ball line. Also,'it; will. be understoodV that the out-` soleernay terminateat its rear end in the region of, the forward. part ofthe. shank cfthe shoe, asin the caseof a half sole.

Thesections of 4the outsoleare secured'together in` edge to .edge relation by rubber cement or other: suitable adhesive .appliedat the surfaces offthe recesses-.and tongues.las indicated at 24thereby f providing waterprcof joints between said sections, and the overlapping tongues are also preferably stitched together by lines of stitching 26 passing After the outsole sections are secured together.

the outsole is rounded, and thereafter the mock welt 28, consisting preferably of a leather strip, is secured to the top of the outsole at the peripheral edge thereof by a line of stitching 30 extending from a point at the rear of the shank at one side of the sole, forwardly to and around the forward end of the sole, and rearwardly to a similar point at the opposite side of the sole. Then the outsole is attached to the vupper and to the insole in accordance with the selected shoe-manufacturing method. The shoe heel 32 is then applied and the shoe is thereafter finished in the usual way, v l

The sectional vconstruction of the outsole described above rnay be Varied. In the form illustrated in Fig. 7, the construction is similar to that shown in Figs. 1 and 3, differing from the latter in the provision of the tongues with transversely extending lips 32 which fit in grooves 34 in the adjacent ends of adjacent sections, respectively, forming an interlooked joint between adjacent sections. Said lips and grooves extend for the full width of the outsole. of the adjacent edge portions of adjacent sections in this form of the outsole is preferably substantially as described above, rubber cement being applied at the joints, for rendering them waterproof, and the overlapping tongues being stitched together. As here shown, however, the overlapped adjacent tongues are preferably secured together by two lines of'stitching as indicated at 26. In Fig. 7, theend sections are indicated at I4a and Mb and the intermediate sections are indicated at |4c, Md and Me. will be understood that after these sections are secured together, the outsole may be treated in substantially the same way as described above in reference to outsole I4 and that amock welt 28 is preferably attached to the outsole as described above.

The outsole illustrated in section in Fig. 4 .is also of the same construction as outsole I4 except that the recesses and tongues are disposed intermediate the thickness of the strips provided therewith, the recesses being indicated at I8' and the tongues being indicated at 20. The securement of the sections by rubber cement and stitching is substantially as described above, the stitching being indicated at 2G.

As shown in Fig. 5, the outsole sections are provided with interfitting tongues and grooves 36 and 38, respectively, providing dove-tailed joints between adjacent sections, and lines of stitching 40 extend widthwise of the sole for securing the adjacent edge portions of adjacent sections to each other. The joints may be waterproofed by applying rubber cement to the vertical edge surfaces of said tongues and grooves which extend preferably for the full thickness of the sole. The construction shown in Fig. 6 is the same as in Fig. except in the rounded contour of the tongues 36 and the grooves 3B.

While I have shown and described the 'preferred embodiment of my invention, it will be understood that the latter may be embodied otherwise than as herein shown or described. Accordingly, I do not wish to be limited to `the invention as herein specifically illustrated or described except to the extent which may be required by the scope of the appended claims.

The securement Having thus described my invention, what I claim and desire to secure by Letters Patent is..

1. An outsole for a shoe, said outsole comprising a shank part formed in a single piece and a; forward part comprising a plurality of leather strips of the thickness of the outsole disposed in. adjacent side by side relation widthwise of the outsole and extending from one side edge of the outsole to theopposite side edge thereof wherebyA said forward part is more flexible than said shank part, lines of stitching ,running widthwise of the outsole and passing through the adjacent marginal side edge portions of adjacent strips for securing said strips together in said side by side relation in the outsole, the outer surfaces of said strips forming the tread surface of said forward part of the outsole, the rear edge of said forward part abutting the forward edge of said shank part, means securing said forward part to said shank part, and a welt-simulating strip positioned over the peripheral marginal edge of said shank and forward parts of the outsole at the top thereof and concealing the joint between said parts and the joints between said strips at the top marginal edge of the outsole.

2. In a shoe having an upper, an outsole secured thereto, said outsole comprising a shank part extending in one piece from the heel to the ball line of the shoe and a forward part extending from the ball line to the front end of the shoe, said shank and forward parts being secured together in abutting edge to edge relation,

said forward part being more flexible than said shank part and comprising a plurality of strips each extending widthwise' of the outsole from one side edge to the opposite side edge thereof and disposed in abutting edge to edge relation, the outer surfaces of said strips forming the tread surface of said forward part of the outsole, and lines of stitching running widthwise of the outsole and securing adjacent strips to each other at the joints therebetween.

3. In a shoe having an upper, an outsole secured thereto, said outsole comprising a shank part extending in one piece fro-m the heel to the ball line of the shoe and a forward part extending from the ball line to the front end of the shoe, said shank and forwardfparts being secured together in abutting `edge to edge relation, said forward part being more flexible than said shank part and comprising a plurality of strips each extending widthwise of the outsole from one side edge to the opposite side edge thereof and disposed in abutting edge to edge relation, the outer surfaces o-f said strips forming the tread surface of said forward part of the outsole, and lines of stitching running widthwise o`f the outsole and securing adjacent strips to each other at the joints therebetween, the rear edge of said forward part abutting the forwardedge of said shank part, means securing said forward part to said shank part, and a welt-simulatingr strip positioned over the peripheral marginal edge of said shank and forward parts of the outsole at the top thereof and concealing the joint between said parts and the joints between said strips at the top marginal edge of the outsole.
