11 claims.

This invention relates to articles of manufacture in which strips are sewed edgewise to sheets and is illustrated herein as exemplified by an insole having strips so attached thereto as to provide ribs to which a shoe upper may be secured.

Objects of the invention are to provide articles of manufacture comprising sheets having strips upstanding from the surfaces thereofv and more y particularly to provide inexpensive insoles for 1o shoes having strips projecting from the'surfaces thereof sufliciently to receive a securing means E for attaching the uppers to the insoles during the lasting operation.

In one aspect the invention consists in an f5" article of manufacture comprising a sheet having a thin strip placed edgewise thereon and a line of stitching the stitches of whichV extend-through the strip from edge to edge and through the sheet. In a, further aspect the invention comprises an insole having a strip projecting from the surface thereof sufciently to receive. the securing means for attaching an upper to the insole during the lasting operation, said strip being secured tothe insole by stitches which eX- 5 tend through the insole and from edge to edge through the strip. As illustrated, one edge face of the strip may be beveled to cause the strip to be inclined toward the median line of the insole.

These and other aspects of the invention will appear more fully from the following description when read in connection with the accompanying drawing and will be pointed out in the appended claims.

In the drawing:-

Figure 1 is a plan of the top side of an insole with the attached upper securing strips according to the invention;

Figs. 2 and 2A are sections, on an enlarged scale, on the lines 2-2 and 2A-2A respectively of. Fig. 1; Y

Fig. 2B illustrates an insole with a modified form of strip, and corresponds to a section on the line 2 2 of Fig. 1;

Fig. 2C is a transverse cross-section of the strip according to Fig. 2B before it is applied to the insole;

Figs. 3 and 4 are sections through the shoe and last, corresponding to the sections on the line 2-2 of Fig. 1, illustrating steps performed in the method of making the shoe;

Fig. 3A is a fragmentary section, corresponding to Fig. 3, showing the modified form of insole and strip according to Figs. 2B and 2C;

According to one form of the invention, the

insole I has secured thereto, at opposite sides (Cl. Sii-22) thereof, strips 3 of suitable material such as leather, or leather substitute such as paper compositions and the like, these strips being of relatively small size, for example, but without limitation thereto, in the order of lg thick and from 1A; to le" high. If desired. the insole may comprisey a heel and shank stifiener which as shown is in the form of a thin sheet 4 of fiber board or the like cemented or otherwise secured to the main portion of the insole before applying the strips. Y

A As illustrated by Figs. 1, 2 and 3, the strips are of rectangular cross-section and are placed edgewise` against the insole and are sewed thereto` byv lines lof stitching 5, the stitches 1 of which preferably'passthroughvthe insole and from edge to edge .through the strip. Bypthis construction rigid abutments are formed for enabling an upper 9 to be drawn over a last li and to be secured to the abutments by staples or other securing means i3.

-In the form of the invention illustrated by Figs. 2B and 2C the strips 3 are inclined inwardly from the edges of the insole, which construction may be desirable to facilitate the stapling operationV When employing certain forms of stapling instrumentalities. For this purpose the edges 8 of the strips contacting with the insole surface are beveled. The strips may be held normally to the insole during the sewing operation and when sewed the tension of the stitches acts .to draw the strips into their inclined positions illustrated.

Before the upper is Worked into lasted position and secured tothe strip 3, forming the insole rib, for example, by staples or the like, cement may be applied to the portion of the insole between its edges and the strips 3, or to the corresponding portions of the uppers, or both, the staples holding the uppers in place until the cement dries. This cementing operation may be facilitated, if desired, by subjecting to pressure that portion of the uppers which overlaps the insole. After the uppers are cemented in position, as indicated in Figs. 3 and 3A, the strips 3 and excess portions of the uppers may be severed by a trimming operation, leaving the shoe in the condition illustrated by Fig. 4 preparatory to apply- Ving the sole. 'I'he method of utilizing my novel insole may be substantially as described in Letters Patent of the United States No. 1,932,545, granted October 31, 1933, on an application of George Goddu.

It will be observed that the stitches passing through the strips edgewise, being under tension and of considerable diameter relative to the thickness of the strips, draw the latter tightly against the insole to form a substantially rigid abutment, which eliminates all substantial tendency of the abutment to bend or tilt during the operation of applying the uppers. Thus is avoided the common defect of prior constructions. Y

It will also be understood that the invention is not limited to insoles or shoes, but comprehends any construction in which a stripI is sewed edgevvise to a sheet or other shape.

The machine for making my novel insole originally disclosed herein is being disclosed and claimed in the divisional application Serial No. 97,839, filed August 25, 1936.

Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. An article of manufacture comprising a sheet having projecting therefrom a relatively thin strip, an edge of which latter lies against said sheet, and a line of stitching, the stitches of which extend through said sheet and from edge to edge through said strip for securing the latter to said sheet.

2. An article of manufacture comprising a sheet having a relatively thin strip projecting therefrom with an edge of said strip against said sheet, the height of said strip being not less than its thickness, and a line of stitching, the stitches of which extend through said sheet and from edge to edge through said strip for securing the latter to said sheet.

3. An article of manufacture comprising a sheet having a relatively thin strip of quadrilateral cross-section projecting therefrom with an edge of said strip against said sheet, and a. line of stitching, the stitches of which extend through said sheet and from edge to edge through said strip for securing the latter to said sheet.

4. An article of manufacture comprising a sheet having projecting therefrom an inclined relatively thin strip, an edge of which latter lies against said sheet, and a line of stitching, the stitches of which extend through said sheet and from edge to edge through said strip for securing the latter to said sheet.

5. An article of manufacture comprising a sheet having projecting therefrom an inclined relatively thin strip formed with a'beveled edge which lies against said sheet, and a line of stitching, the stitches of which extend through said sheet and from edge to edge through said strip for securing the latter to said sheet.

Y

l0. An insole Yhaving, a relativelyhigh and thin strip projecting from the insole surface with an edge of said strip against said surface, said strip being adapted to receive the staples for securing the uppers during the lasting operation and being secured to the insole .by a line of stitching, the stitches of which extend through said insole and strip from the side of said insole opposite said strip to the remote side of said strip. Y
