INNER SOLE Filed May 19, 1928 A W r Patented Ang. 2.7, 1929.
ROBERT r. FRYE, or MARLBORO, MASSACHUSETTS.
INNEB SOLE.
Application filed May 19,
The invention relates to inner soles for welted shoes, and it has for its object to produce a desirably ineXpensive inner sole, having sufcient strength and stability to hold the upper in the form imparted to it by the lasting operation.
Other objec'ts appear description of my improved the statement of the advantages thereof.
Of the accompanying drawings forming a part of this specification,-
Figure 1 is a bottom View of an inner sole embodying the invention, looking toward the side from which the inseam stitch-receiving rib projects, portions of the two flexible strips constituting the rib and the anchoring apron hereinafter described, being shown by 'full lines, and other portions bydotted lines.
Figur-e 2 is a section on line ure 1.
Figure 3 is an enlargement of a portion of Figure 2.
Figures 4: and 5 are fragmentary perspectiVe views, each showing on a much enlarged scale a portion of the inner sole body, and portions of the two fiexible strips, said strips being in approximately the forms they assume and the positions they occupy in relation to the insole body before the completion of the rib, Figure 5 showing a slight modification. I I
Figure 6 is an enlarged fragmentary sectional view, showing the fiexible strips in substantially the positions they occupy during the stitchir'g operation.
The same reference characters indicate the same parts in all of the figures.
The insole body 12 maybeof any suitable material, or combination of materials, and may include an inner layer of leather, and an outer layer of some cheaper material, such as leather board.
The body is provided with aninseam stitch-receiving rib, spaced inwardly from the margin of the body, as usual in insoles for welted shoes. With the body and rib is associated an anchoring apron secured to the body at the inner side of the rib and constituting a feature of my improvement.
The rib is laminated and the anchorng apron is integral with one of the layers of the rib. The rib and apron are composed of two fieXible strips, preferably of teXtile fabrc, such as cotton duck, and each strip may be a length of woven tape having sel- 2-2 of Figfrom the following inner sole and' 1928. Serial No. %79,173.
Vage edges, or it may be cut from sheet material and have a raw edge or edges, one set of the crossing threads being preferably parallel'with the longitudinal edges of the strip, so that the strip diii'ers from one which is cut on the bias.
One of the strips which I call the outer i strip, is folded longitudinally to' form; two Contacting layers 13 and 14 of the laminated rib, and a necl( 15 connecting said layers, and secured by a row of outer stitches 16 to the body, the stitches being spaced from the margin of the body and extending substantially parallel thcrewith. The layer 13 is the outer layer, and the layer 14 an intermediate layer of the rib. The other strip which I call the inner strip, is bent or partially folded longitudinally, so that its cross section is angular, the inner strip including an anchoring apron 17, which is secured to the body 1:2 at the inner side of the rib, and a fiap 18, which Contacts with the intermediate rib layer l l, and constitutes the inner layer of the rib, the latter being therefo re composed of three plies or layers.
The outer edge portion of the anchoring apron 17 is secured to the body by a row of inner stitches 19, extending parallel with the outer stitches 16 and spaced inwardly therefrom. The parallel-rows of stitches 16 and 19 may be 'ormed simultaneously by a suitable two-needle sewing-machine, preferably of the lock-stitch type, the two strips being "guided simultaneously to the body, and located thereon substantially as indicated by Figure 6, so that the two strips are Secured by a single operation. If desired, the bend or neck connecting the portions 17 and 18 of the inner strip, may project slightly into the path of the needle employed in forming the stitches 16, so that said stitches secure the inner portion of the anchoring apron 17 to the body, as shown by Figure 5.
The rib layers are united to each other, so that they form a rib of sufiicient thickness projecting from one side of the body. This union is eflected preferably by providing the outer strip which includes the rib layers 13 and 14-, with an adhesive coatng 20, indicated by heavy black lines in Figures 3, 4, 5 and 6, and by providing the inner strip with a similar coating 21.
The strips may be prepared by spreading on one side of each strip any suitable fluid or semi-fluid material, which is adherent to the strip, and allowing the material to dry,
the nature of the material being such that it is adapted to be rendered substantially nonsticky by drying, and to be softened and rendered Sticky or tacky by hoat. A suitable material is known to the trade as gem coating or guttasiad and nay contain gutta percha, or some other form of rubber.
After the stitching operation, the prevously dried and hardened coatings are rendered soft and Sticky by'heat, and while the coatings are in this condition, the strips are acted on by a lip-setting machine which pressesthe Sticky coatings on the lip layers 13, 14 and 18 together, and the Sticky coating on the apron 17 against the body, so that the lip layers are caused to firmly adhere to each other and form a suitably stili lip, and the apron is caused to rmly adhere to the body.
The layers 13, 14 and 18 are narrower than the apron 17, so that the layers may be tenporarily displaced and lie substantially fiat on the body, as shown by Figure 6, and on a sewing-nachine bed plate to expose the stitch-receiving portions of 'the two strips, during the stitching operation.
The displaced strips are so located on the body 12 while being stitched, that the edge of the apron, which receives the stitches 19 is exposed, to receive said stitches and the neck portion of the outer strip is exposcd to receive the stitches 16, the rb layers 1 1 and 18 partly, but not entirely overlapping the apron.
The inner strip is folded when first applied to the body, the apron hearing;` on the body, and the layer 18 on the apron, and the outer strip is substantially flat when first applied to the body, its rb layer 1 1 overlapping the layer 18, all as shown by Figure 6. The bed or throat plate of the sewingmachine may, therefore, be flat, as usual, it being nnnecessary to provide a bed plate which is specially fornied or recessed to accoinmodate the material being stitched.
The inner sole made as above described, possesses the following conbination of advantages over any others of which I am aware:
The rb is secured to the body not only by the stitches 16, but also by the anchoring apron 17, the latter being so firmly Secured to the body that it may be much narrower than the Width of the body, as shown by Figure 1, a marked saving of material being thus efiected.
The inner row of stitches 19 is ont of the path of the needle used in forming the inseain stitches and cannot be cut thereby. The marginal portion of the under side of the body from which the rib projects, and on which the shoe upper bears, is eXposed, there being no fabric thereon.
The inner row of stitches 19 so confines the outer ed -e portion of the anchoring apron it is not liable to be pulled away from the body during the inseam stitching operation.
The two strips constituting 'the rib and the anchoring` apron are Secured to the body by two parallel rows of stitches simultaneously t'ormed, so that the'time required by the stitching operation is reduced to a minimum.
I claim:
A reinforced insole of the character stated, comprising a body, a tlexible outer strip folded to form an enter and an intermediate rb layer and a neck connecting said layers, outer stitches extcnding approximately parallel with and spaced from the margin of the body and secnring the neck thereto, a flexible inner strip including an apron superinposed on the body, and an .inner rb layer standing at an angle to the apron, and inner stitches eX- tending arallel with and spaced inwardly from the outer stitches and securing the inner edge portion of the inner strip to the body, means for secnring the outer and intermediate rib layers to each other and the inner layer to the intermediate layer, the apron being wider than the several rb layers, so that the intermediate and inner layer may be temporarily located parallel with each other and with the body to expose the stitchreceiving portions of the two strips, and permit the snultaneous :formation of the outer and inner stitches.
In testimony whereof I have afiixed'iny signature.
