I then apply ythe prepared insole tothe cene thereofv in cross-section on line 2, 2,

with, with the .outer soleconnected to the y welt by the outseam.

Referrin to the drawings, as above'referredto, subject the blank for the insole l to anoperation Iby which its marginal por. tion is molded to form the upstanding flange 2. Theangle I which the flange is caused to assume with relation to the plane of the tread-surface of the insole may vary in practice. In producing the insole, I take a blank of proper size, of a thin `iieirible material, and form thefiange thereon by a simple bending of themarginal or edgefportion of the blank so as to cause it to stand at the required angle to the said plane, and by means of the bending operation I caus'el the ange to become set in the desired position.

Along the line of the bend, the insole is without any channel or groove, and consequently the entire thickness of the marginal portion of the insolejalong` the line of the bend is included in the bend. The outer face of theflange is a continuation of that surface of the body-portion, z'. e.,`intermediate portion ofthe insole, which in the lasting operation facesuthe sole of the last 4l, and which during the wearing of the shoe receivesthe rlirect 'pressure of the wearers foot. Cons r "quently, the insole has nol so-called feather.

In Figs. 3, 4, 5, the upper is marked 3,

and 4 is the lastr within the upper, 5 being the welt. A lining isindicated at m. In folA lowing out my method l. apply the prepared insole of Figs. l and 2 Ato the last las in Fio. 3, ydraw the u er and lining inward n a i around and over the marg1n of the last, vand place the margins of the upper and lining directly vagainst the outerl'surface of the.,

molded flange 2, as in Fig. 'Ialsoplace a welt 5 against the exterior of the upper as inA saidV figure, and secure the welt, upper, lining, and insole together by a line o`f stitches 6 passing through the `entire thickness of the Harige and located at the angle or bend of the la'tter, thereby forming the inseam, the result being as shown in Fig. 3.

- The flange serves as a guide during the stitching operation, and preserves or maintains the regularity of the stitching. I thenf trim off the margins of the welt, upper, lining, and molded insole-flange close to the 1nseain, as in Fig. 4L., after which l flatten out f rthe welt so as to cause it to stand out. I

and a feather.

then apply a cushion 7 to the exposed outer surface of the insole, within the trimmed molded flange, and next apply an outer sole 8, fastening said outer sole to the welt by means lof stitches 9 passing vertically through the welt and the sole 8 and constisuitable tough and flexible material, such for instance as cloth, which would not permit a cutting or channeling operation. Soft or chrome-tanncd leathers may also be employed. Bybending the insole without cutting or channeling, I am enabled to retain the entire strength of the material of the insole without diminution, and to get the benefit of the toughness of the grain side of the leather when that remains on the insoleblank, the grain being the toughestportion of the leather.

My method dispenses with the usual operation of channeling the insole to form a lip It omits the feather altogether, but nevertheless enables the same overhan of the upper of the shoe to be attained at heretofore has necessitated the formation of a feather upon the insole of a welt shoe. It renders unnecessary the employment of channel-openers and the like and the sewing machine by which the inseam is sewed. It allows the use of an insole of extremely'fiexible material. The omission of.A a feather secures in the completed shoe the advantage that there is nothing to form a ridgebeneath .the wearers foot, and to curl out of shape and hurt the foot.

As I have; stated above, the flange of the insole serves as a guide hduring the stitching operation, and preserves or maintains the regularity of the stitching. The stitching is gaged from the innerv angle of the bend of the flange with relation to the body of theinsole, and the upper and lining are held close against the outer surface of the flange, thereby securing regularity in the shape of the shoe. s, 1

'shoe made` by my method has extreme fiexibility in the sole thereof, attained by so shaping the insole as to permit a firm inseam to be secured on stock that is unfitted or too thin to be channeled. The shoe is absolutely smooth inside, inasmuch as the edge of the insole is so secured to the welt and upper that the margin of the insole cannot turn up in course of drying after being moistened to forni a ridge to hurt the wearers foot.

l claim as my invention l. The improved method of making a welt shoe which comprises the. steps of taking a thin flexible insole-blank, producing an upstandingedge-Harige or lip thereon by a bend around the margin et' the vvsaid blank delining the. extreme outer boundary of the.
