Patented Sept. 23, 1947 RIBBED INSOLE Hans C. Paulsen, Medford, Mass, assignor to B. B. ChemicalCo, Boston, Mass, a corporation of Massachusetts Application October 22, 1945, Serial No. 623,696-

16 Claims. 1i

This invention relates-to insoles and, more particularly, to insoles provided with sewing ribs and to strips for use in forming sewing ribs on insoles to adapt them for use in the manufacture of welted shoes.

An important object of the present invention is to provide an improvedinsole of relatively thin material having-a strong'upstanding sewing rib permanently attached to its outer surface. A further object of the invention is to provide improved strips for use informing sewing ribs on insoles.

To the accomplishment of these objects, the invention provides, in accordance with one-aspect, an improved-insole comprising aninsole-shaped body of relatively thin materialprovidedonits outer surface with a sewing ribwhich extends around themarginal portion of said insole body; The sewing rib, as herein illustrated, comprises an integral strip'of flexible sheet material folded to form a four-ply rib having integral flanges extending from opposite sides thereof.

The strip, as illustrated herein; is coated'on one side with cement, preferably a pressureresponsive cement, and the folding is done in a directionto' bring the cemented surface against itself to cause the layers to adhere to each other to form a two-ply layer. The two-ply layer is then folded to produce afour-ply portion" with remaining portions of the strip extending there'- from. In order to hold the plies of the four-ply portion together, stitches are inserted into said portion, the stitches passing through at least three plies thereof. The stitches also establish a lineof division between the four-ply portion and the remaining portions-of the-strip projecting therefrom. The strip is now ready to be attached to an insole body toprovide a sewing rib thereon.

In attaching the strip to the insole body, the four-ply portion is bent upwardly substantially at right angles to the plane of said insole body to provide a four-ply upstanding sewing rib and the remaining portions of the strip, which proe ject from the four-ply portion, aresimultaneously pressed flat against the surfaceof the insole-body at opposite sides of the rib'to form integral inner and outer flanges, the outer flange preferably terminating at, or a short distancesinward'ly of, the edge of' the insole body and the inner flange covering a substantial. portion of. said insole body inwardly of the rib;

The integral ribbed. strip, asherein illustrated, is attached to the outer surface of the. insole body by means of the pressure-responsive cement on the strip and a band of cement, preferably the samekind J of cement, extending around the marginal portionofsaid outer surface. Theattachment ofthe ribbed strip to the insole body is particularly strong by reason of the wide inner flange which not only helps to secure the strip permanently to the insole body butserves also to reinforce said insole body. The outer: flange assists in maintaining the m'ulti-ply rib in its upstanding position orin returning the rib to such position if it is bent outwardly during the lasting orinseamin-g operations in the. manufacture of the shoe. The illustrated rib is well adapted-to receive stitches, staples orother fastening. means which may be used in the operationsreferred to and, owingto the fact that the rib and flanges are integral, there is practically no danger of 'the rib tearing away from the flanges under the strains exerted-by the upper during or after the lasting and inseaming operations.

In accordance with anotheraspect, the invention provides an improved ribbed strip for use in forming sewing ribs on insoles comprising a single strip of flexible sheet material of indefinite length folded toprovide a four-ply portion or rib extending lengthwise of thestrip and having portions extending therefrom whichform integral flangesat opposite sidesof the rib, the lower surfacesof said flanges being coated with cement, preferably a pressure-responsive cement.

The above and other features and aspects of the invention-,- including modifications of the ribbed strip, will appear'more fully from the following detailed description when read in connection with thea'ccompanying drawings and will thereafter-be pointed out in the claims.

In making the integral ribbed strip of the present invention for providing sewing ribs on insoles. a relatively wide strip S of indefinite length is provided composed of a single strip of flexible sheet material, such as Gem duck, canvas or similar fabric, the lower surface of the strip, as viewed in Fig. 1, being coated with cement C, preferably a pressure-responsive cement such as rubber cement, neoprene, latex or other cements comprising synthetic rubber-like materials. The strip is folded, as illustrated in Fig. 1, to form a fourply portion R which is subsequently to form the sewing rib, the portion R extending lengthwise of the strip along one margin thereof. The remaining portions of the strip extend from one side of the four-ply portion after folding, these remaining portions in Fig. 1 comprising a single ply layer I and a two-ply layer F.

After the strip has been foldedas described, a row of stitches is inserted into the four-ply portion R, the stitches passing through all four plies and securing the plies permanently together and also establishing a line of division between the portion R and the remaining portions I and F extending therefrom. As illustrated in Figs. 1 and 2, the strip is initially folded so that the cemented lower surface is brought against itself thereby causing the layers to adhere to each other to form a two-ply layer which is then folded again to form the four-ply layer R which, in turn, is secured together by the stitches 20. The strip S in the condition shown in Figs. 1 and 2 is ready for attachment to an insole and may be wound upon a reel 22, as illustrated in Fig. 3, to facilitate handling the strip or shipping it to manufacturers.

The strip S is attached to an insole 24, as illustrated in Fig. 4, the strip being fed from the reel 22 and applied progressively to the outer surface of the insole by a machine adapted to attach the strip, such a machine being disclosed in Letters Patent of the United States No. 2,383,560, granted August 28, 1945, upon an application filed in my name, although other machines may be used if desired. As the folded strip S is fed from the reel 22, the four-ply portion R passes through a guide on the machine which bends said portion upwardly along the line of stitches 20 substantially at right angles to the body of the insole, the machine simultaneously pressing the integral flange portions I and F of the strip against the insole to provide an insole having an upstanding four-ply sewing rib R having integral inner and outer flanges I and F, the outer flange F terminating substantially at the edge of the insole around the forepart thereof and terminating a short distance inwardly of the edge of the insole at its shank portion. The inner flange I, as shown in Fig. 4, preferably covers a substantial portion of the insole body inwardly of the rib and thus provides a strong bond between the strip and the insole as Well as serving to reinforce the insole body in place of an overall canvas reinforcement which is sometimes used on thin flexible insoles of relatively cheap material. The outer surface of the insole 24 is provided with a band of cement 26, preferably a pressure-responsive cement of the same type as is applied to the lower surface of the strip, so that when the strip is fed to the insole by the ribbed-strip-attaching machine, the flanges F and I will adhere firmly to the insole body as they are pressed against said body by the machine. The ribbed strip extends around the marginal portion of the insole from approximately the heel-breast line at one side thereof to the heelbreast line at the opposite side. The machine is provided with a cut-off knife which severs the strip at the heel-breast line after it has been attached to the insole body as described. As illustrated in Fig. 1, the outer flange F of the strip consists of a two-ply layer while the wide inner flange I comprises a single-ply layer.

Figs. 6 and 7 illustrate a modified form of ribbed strip S which may be used to provide a sewing rib on insoles. The strip of Fig. 6 is folded over, as described above, to form a two-ply layer which, in turn, is folded to form a four-ply layer R having two two-ply layers F and I extending from one side thereof. Stitches 2!] are inserted through the four-ply layer R. to hold the plies together and form a line of division between the portion R and the extending portions F and I. The strip is attached to an insole 24, as illustrated in Fig. 7, the four-ply portion R forming the upstanding rib and the two two-ply portions F and I forming outer and inner flanges, respectively, integral with the rib, the two-ply outer flange F terminating inwardly of the edge of the insole at the shank portion, as shown in Fig. 7, and the two-ply inner flange I. together with a single ply portion K of the strip, covering a substantial portion of the insole body inwardly of the rib R. Pressure-responsive cement C is provided on the lower surface of the strip and, when brought into contact with the same kind of cement on the insole body, causes the ribbed strip to become permanently attached to said insole body.

The strips illustrated in Figs. 8 to 15, inclusive, are modifications of the strips shown in Figs. 1 to '7. The strip S of Fig. 8 has pressure-responsive cement C on its upper surface and is folded over at one margin to form a four-ply layer R, a two-ply layer T being first formed and secured by stitches 28, after which the remaining portions of the strip are folded back upon the two-ply layer to form the four-ply layer R. As shown in Fig. 8, stitches 20 are inserted through the fourply layer R and the remaining portions of the strip extend outwardly from one side of the four-ply layer to form single ply inner and outer flanges I and F integral with the rib R. The ribbed strip S is attached to the insole 24, as shown in Fig. 9.

In Fig. 10, the strip is folded to form a threeply portion R having single-ply portions I and F projecting from the opposite sides thereof. Stitches 20 secure the three plies of the portion R. together. The strip is applied to the insole 24, as shown in Fig. 11, the portion I forming the fourth ply of the rib R and theremaining portion thereof forming an integral single my inner flange I. The pressure-responsive cement C on the bottomsu'rface of the strip' and the same kind of cement '26 on the insole causes the ribbed strip toad-here permanently to the Outer surface of the insole, as shown in Fig. 11.

In 12,'the strip Sis folded to form a fourply layer R having two single-ply'layers F and I projecting from one side thereof. Stitches 20 secure the four plies of the portion R together. The ribbed strip is attached to the insole 24, as shown in Fig. 13, the single-ply portion F forming the outer flange and the wide single-ply portion I formingthe inner flange.

Figs, 14 and 15 illustrate a further modification of the ribbedstrip. As shown in Fig. 14, the strip S is folded to form a three-ply portion R having a single-ply layer F extending from one side thereof and a wide single-ply layer I extending from the opposite side thereof. Pressure-responsive cement C is on the upper or at taching surface of the strip, as viewed in Fig. 14. Stitches secure the three plies of the rib together. The strip is applied to an insole 25, as illustrated in Fig. 15, the single-ply portion F forming the outer flange and the wide single-ply portion I forming the inner flange. The cement C and 26 on the strip and ins01e body, respectively, causes the strip to adhere permanently to said insole body.
