2 Claims.

[his invention relates to manufacture of shoes :1 is herein illustrated in its application to the .nufacture of turn welt shoes and in particular the adaptation of turn welt shoemaking to off- :-last methods of shoe manufacture. in the manufacture of turn welt shoes by tl'iods heretofore practiced the upper is lasted ide out over one last and attached to an ine on the last bottom and the shoe thus conucted after removal from said last is reversed d mounted on another last and completed. e cost of providing and maintaining two comte assortments of lasts constitutes a major item expense in the manufacture of turn welt shoes methods heretofore known and practiced. It is object of the present invention to eliminate a use of the first last and thus effect a sub- .ntial economy in the manufacture of shoes of s type.

With the above object in view the present inntion consists in a method of making shoes rich comprises providing a prefitted upper, ;tening to the bottom margin of the upper inner strip and an outer strip which may be her a sole attaching welt or a platform wrapr, turning the upper inside out, fastening to a bottom margin of the upper a flexible insole less than last bottom area, turning the shoe made right side out, turning the inner strip on itself and arranging it to cover its own ge portion and the adjacent edge portions of e upper, the insole, and the outer strip, secursaid inner strip to the insole, and completthe shoe by securing a sole to said outer 'ip or, alternatively, by mounting a platform ie on the shoe bottom, wrapping the outer strip ound the margin of the platform sole, securing e outer strip to said platform sole and finally :uring an outsole to the shoe bottom. In the drawings, Fig. 1 is a cross sectional view illustrating a rtion of an upper turned inside out and having welt and a cover strip stitched to its bottom argin; Fig. 2 is a cross sectional view similar to Fig. 1 owing a flexible insole stitched to the welted argin of the upper; Fig. 3 is a cross sectional view showing the vrtion of a shoe illustrated in Fig. 2 turned right ie out;

Fig. 4 is a cross sectional view showing the portion of a shoe illustrated in Fig. 3 with the cover strip brought into contact with the insole; and

Fig. 5 is a cross sectional view similar to Fig. 4 showing an outsole stiched to the welt.

In the illustrated construction a relatively wide strip 42 is secured to the inner surface of the margin of a prefitted upper 44 by stitches 46 which also secure a welt 48 to the outer surface of the upper. A flexible insole 5D is secured to the welted margin of the upper by stitches 52, After trimming the substance extending beyond the seam 52 the upper is reversed thus providing the structure shown in Fig. 3. The strip 42 is then turned about its attached marginal portion so as to cover the adjacent edge faces of the insole, the welt and the upper, and is attached to the margin of the insole, preferably by cement as shown in Fig. 4. A last 5 3 is then inserted into the shoe thus constructed whereupon an outsole 56 is laid on the shoe bottom and attached to the outwardly extending margin of the welt 48 by stitches 58.

It will be understood that a platform wrapper could be provided in the shoe illustrated in Fig. 5 in place of the welt 48 and the shoe could be provided with a platform sole.

In the illustrated construction, the welt may be extended around the heel portion of the shoe, or if desired the welt may be omitted from the heel portion of the shoe in order that the upper may be heel seat lasted. It will be understood that if the upper is to be heel seat lasted a heel piece or a conventional insole is mounted on the last before the last is inserted into the shoe. The conventional insole may if desired be provided with any known type of shank stiffening means.

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

1. That method of making shoes which comprises providing a prefitted upper, fastening to the bottom margin of the upper an inner strip and an outer strip, turning the upper inside out, thereafter fastening to the bottom margin of the upper a flexible insole of less than last bottom area, turning the shoe so made right side out, turning the inner strip upon itself and ar- 3 ranging it to cover its own edge portion and the adjacent edge portions of the upper, the insole, and the outer strip, securing said inner strip to the insole, and securing a sole to said outer strip.

2. That method of making shoes which comprises providing a prefitted upper, fastening to the bottom margin of the upper an inner strip and an outer strip, turning the upper inside out, thereafter fastening to the bottom margin of the upper a flexible insole of less than last bottom area, turning the shoe so made right side out, turningthe inner strip upon itself and arranging it to cover its own edge portion and the adjacent edge portions of the upper, the insole, and the outer strip, securing said inner strip to the insole, mounting a platform sole on the shoe bottom, wrapping the outer strip around the mar- 4 gin of the platform sole, securing the outer s to said platform sole, and finally securing outsole to the shoe bottom.
