PERCY WI; VALENTINE, OF NATICK, MASSACHUSETTS ATTAOHZAIBLE RIBBING FOR INNERSOLES AND INNERSOLE EQUII PE D THERCEWITH Application filed. October 18,'1828. Serial No. 313,252.

This invention relates {to material for attachment to innersoles to provide the rib in which the stitches of the inseam are placed for securing the upper, innersole 5 and welt together in the manufacture .of

welt-shoes. It has long beenacoinmonpractiee to make innersole-bodies out of leather of inferior quality, leather-board, andother materials which a-re either not strong enough '1 or not thick enough to permit of the stitch .20 thereof through which the stitches" are passed in. attaching the rib to the body of 'the:sole.' V

The ribs so formed are usually rein-forced,

either by asepa-rate strip of material placed betweenthe folds of the fabric forming "the rib proper, or by an integral part of the fabric strip folded back under one of the *attaching 'flanges and turned up at its edge int'o'the rib proper. Both of-fthese modes of reinforcement provide three thicknesses of material in the rib, and the second one also makes one of 'the attaching flanges a two-ply structure. Both require material in excess of that 'neededto-make merely the rib proper and itsfianges, and alsoa'special operation, that of placing the reinforcing strip or fiap properly within'ithe rib, and the ribbing o f both-these descriptions which is made as a finding for sale to shoe makers, 0 is stitched at the base of the ribproper to hold-the rib-inshape and the reinforcement in place.

My object is to provide a manufactured textile'rib or-ribbing for the use above indicated, containing in its 'woven "structure means for securing together the plies which make the sides ofithe rib proper, andthereby reinforcing the rib. Secondary objects resulting from the "foregoing are the 'saving immaterial andlabor througheliniination-of reinforcing material and of the operations of foldingthe rib and stitching its sides together; and the formation of non-raveling edges on both flanges of the rib.-

The invention comprises a new ribbing for the purpose specified which is woven with binder threads or yarns passing back and forth between the plies of the rib proper and having selvages :a't the edgesof both flanges; and it further comprises a complete innersole consisting of a body combined with an attachedrib 0f the character above set forth.

In the drawings, v

Fig. l is a plan view, and Fig. 2 a crossi651 section on line 2-2 of Fig. 1, of an innersole embodying the present invention;

W Fig. dis a perspective view on an enlarged scale of afragmentofTibbing material embodying this invention; Pg. 4 is a cross-section on line 44 of Fig. 3, drawnon a still larger scale illustrating the woven construction of'the material; h ii) Figs. 5 and 6 are longitudinalsections on lines 5-5 and 6- -6, respectively, of Fig. 4, further illustrating the construction.

7 The innersole comprises abody wand an applied strip of ribbing material having a ribproper b and flanges or flaps c and d, which are attached to the body by sewed seams-e, f and-g. In the elements and mode of connection thus far described, the present invention does not differ from articles of the prior art. Its novelty consists in the structural characteristics of the rib, and in the new combination comprised by the union of such novel rib with an. inners ole body which may be either new'or .old.

Referring now to the structural detail views, Figs. 4, 5 and 6, the ribbing material is seen to be a woven fabric consisting of warp threads 1, l, andweft or filling threads .2. The rib 6 consists of an intermediate part of the fabric doubledto form two plies which lie-contiguous to one another and are securely held in that relationship by binder warps 3, 3.

V The binder warps are interwoven with the filllng threads in the course of original manufacture of the material. By a suitable arrangement of warp threads and harnesses, the shuttle thread is caused to pass between the warps of the flange (Z, for instance, and the adjacent ply of the rib proper, then reverse, to pass between the warps of the op posite ply of the rib proper and those of the flange c. 11 again reversing, with change of the sheds, the filling thread passes in the opposite order between the warps of the flange c and the adjacent ply of the rib proper, and then between those of the other ply and the adjacent flange d. During weaving, of course, the flanges o and (Z are parallel to one another. The binder warps are placed in a width sufiicient to tie together the two lies thus woven for a width equal to the desired hei htof the rib proper, leaving them unconnected for the rest of their width, and therefore in a condition to be separated and spread apart at right anles to the rib proper when applied to the 0d of the innersole.

e weaving method above described is not my invention and is not claimed as such herein. But the application of this or any equivalent method to the production of an innersole rib, and the ribbing material having the resultant characteristics, are my invention, for which I claim adequate protection.

The article containing the characteristics above described has numerous obvious advantages, among which may be named the following:

The side plies of the rib, being tied together, not only throughout the length of the rib but also at frequent intervals from base to summit, are not only prevented from separating, but are also reinforced and stiffened, each by the other. Thus the rib requires no additional reinforcement to hold it upright when attached to the sole. The outer edges of both flanges are selvages, wherefore they will not ravel. This is a feature not possessed by ribbing made of strips cut from a sheet of cloth, for both edges of all strips so out, except those out from the extreme edges of the sheet, are raw edges; and even the strips cut from the edges of the sheet are raw at one edge. These useful characteristics are obtained with the utmost economy, for there is no separate reinforcing strip or cord, neither is it necessary to provide the strip with excess width in order to provide material to fold back under one of the flanges and into the rib proper; and the additional operations of placing the reinforcement and stitching the sides of the rib together are obviated. Instead only the minimum of material needed to make a rib of given height with flanges of given widths is used, and the binding together of the sides of the rib is performed in the course of weaving the fabric.

What I claim and desire to secure by Letters Patent is:

1. An innersole comprising a body and a separate attached stitch-receiving rib formed of textile fabric, having contiguous plies forming the sides of the rib, and binder warps interwoven with filling threads of both lies.

2. n innersole comprising a body and a separate attached stitch-receiving rib made of textile fabric; said rib having a rib proper formed of plies of the fabric arranged side by side and flanges projecting oppositely to one another from the base of such rib, and including structural strands or threads interwoven with both plies.

3. Fabric ribbing for innersoles comprising a woven structure having plies arranged side by side to form a rib proper and structural strands woven back and forth between said plies in the rib proper.

4. Fabric ribbing for innersoles comprising a woven structure having plies arranged side by side to form a rib proper and including binder strands woven back and forth between said plies; one of the plies being extended from the part in which said binder strands are located and from the other ply, to form an attachable flange.

5. A rib strip for attachment to innersoles having a rib proper and separate attachin flanges at opposite sides of the base of sai rib proper; said strip being composed of a woven fabric doubled longitudinally in its middle part to form plies extending side by side between the summit and the base of the rib and including structural strands interwoven with both of said plies.

6. A rib strip for attachment to innersole bodies comprising a textile fabric having a warp and filling strands doubled lengthwise throughout a portion of the width of the strip to form a rib proper, and binder strands interwoven with the crossin strands in those parts of both plies which form the sides of the rib proper.

7. A rib strip for attachment to innersoles, having a rib proper and attaching flanges at opposite sides of the base of the rib pro-per; said strip being a unitary fabric composed of interwoven warp and weft strands and binder strands woven through the rib proper, and formed with selvages at the outer edges of both flanges.

8. A textile fabric rib strip for attachment to innersoles, comprising a two-ply ribproper containing binder strands inter-' woven with both plies thereof, and single ply flanges each being a part of one of said plies.

9. A fabric stri 3 adapted to provide the stitch-receiving ri s of innersoles, compris ing textile fabric plies extending side by side and containing interwoven binder strands in a fractional part of their width, which part constitutes the rib proper, and said plies being otherwise unconnected from the rib proper to their outer edges and adapted to form flanges.

10. A fabric strip adapted to provide the stitch-receiving rib of an innersole consisting of interwoven longitudinal warp and transverse weft or filling threads, the fabric so formed having selvages at both edges and being of folded formation intermediate such edges to provide two plies lying side by side from the fold; a part of the warp threads being binder warps passing back and forth between the wefts of said plies in a portion only of the width from the fold to the nearer selvage edge, forming thereby a rib proper; the plies of the fabric adjacent to said selvage edges being separable from one another and providing flanges for attachment to the body of an innersole.

In testimony whereof I have aflixed my signature.

PERCY W. VALENTINE.
