Description

leather turn sole and it is also oi such proportion as' readily to receive a. series of single face stitches such as are ordinarily used to attach a shoe upper to a turn sole. lin order to insure a strong attachment of a shoeupper to the stitch receiving rib 4, a layer of relatively heavy canvas 8 extending across the upper side of the 'orepart and.

- covering the rib is vulcanized to the rubber body 2. The transversely extending rear edge of the forepart 2 is preferably provided with a downwardly and rearwardly inclined bevel vl extending from edge to edge, this bevel being conveniently formed when. the forepart is iirst molded prior to vulcaniaation.

As herein provided the complemental shank part l2 of the sole which also preferably includes a heel portion 14 consists or" a iirm'er and less flexible material than the rubber compound forepart and of a nonstretchable or inelastic fibrous character, a suitable material for this purpose being leather which vmaterial will hereinafter be referred to without limitation as to analogous materials such as leather-board, berboard and the like. This leather shank part 12 is of a suicient thickness to impart iirmness and stiffness to theshanlr portion of the shoe and to be shouldered and vchanneled in a similar manner to that of an allf'leather turn sole. The forward edge of this shank part 12 is provided with a bevel 16 which is adapted-to overlap the bevel at the rear edgeof the 'torepart 2 and both parts land l2 arepreferably permanently secured togetlier to form a unitary sole blank by vulliti canisation, this being conveniently done when the rubber forepart isvulcanized. The upper side of the fibrous shankpart l2 is provided with the usual turn sole channel and shoulder 22, the stitch receiving strueture 20, 22 there formed being a continua tion of the projecting sewing rib e on the 'orepart 2 ot the sole as illustrated in Fig. 2. Preferably the canvas-reinforce 8 on. the

' 'forepart 2 of the sole is extended back on to the shank part 12 to reinforce the connection between the `orepart and shank part as illus trated and9 if desired,it/may also cover me stitch receiving element., the canvas being secured to the shanlry part by cement.

ln the use of the sole of the present invention, it is :first assembled on a last together with a shoe upper in the usual manner. After the upper has been lasted over on to the sole in the customary way, it is secured to the sole by blind or single faced stitches passing through the continuous sewing element 4f, 20, 22, on' the upper side of the sole. The rear end or heel portion of the shank part 14 being of the same material as the part 14 of the sole enables a firm and properly shapedheel seat to be produced for the attachment ot o. heel 32.

menor-r vided for turn shoes has bccn due to the diiiculty in obtaining sullicient rigidity for the shank portion of the shoe properly to 'f support the foot and to the impossibility of conforming the shank portion of a rubber sole to the conformation of the last and maintaining it in such condition owing to the sin `le sole construction of shoes of this type. iowever, by reason of thc inelastic and nonstretchable fibrous character of the material in the shank part of the sole of the invention, this disadvantage is entirely eliminated and the sole may be conformed to the curvature of the corresponding portion ot the last with the same facility as a leather sole and also will maintain its conformed condition after the last is withdrawn from the shoe thereby adding appreciably to the neat and stylish appearance of the shoe in the shank.

lt will be seen that a shoe having a sole as above described has all of the desirable qualities found in rubber solo shoes in general and in addition includes all of the advantages particularly as to appearance and wearing qualities of an all-leather sole turn shoe. Furthermore, the iibrous backing on the rubber body forepart of the sole. provides an eti'ective insulation for the foot -and thus renders the shoe much more comfortable. Also, if desired, a shank piecel may be incorporated in the shoe in the same manner as in a leather turn shoe to provide additional support vfor the foot of the wearer and assist in maintaining the shape of the shoe.
