SHOE AND METHOD OF MAKING THE SAME.

Application filed January 22, 1921. Serial No. 439,254.

To all whom it may concern:

Be it known that 1, JAMES H. Rani), a citizen of the United States, residing at Swampscott, county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Shoes and Methods of Making theSame, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to the manufacture of boots and shoes and has for its object a shoe which can be more cheaply constructed than shoes heretofore in use and which shall have the durability and ossibilities of repair heretofore found chiefly in so-called Goodyear welt shoes.

Heretofore, machine-made shoes have been chiefly of three types-(1) the turn shoe, (2) the Goodyear welt shoe, and (3) the McKay shoe. As is well understood by those skilled in the art, turn shoes are limited to shoes constructed of light flexible materials capable of being turned inside out during the rocess of manufacture. Goodyear welt s oes are the most durable and satisfactory construction, particularly for heavy shoes, as they wear much longer than either of the other two types and are capable of repeated repair, methods of repairing having been devised by which the shoe can be restored to almost its original condition.

Goodyear welt shoes are, however, relatively expensive to manufacture on account of the number and intricacy of the processes to which they must be subjected during manufacture.

I The McKay shoe can be constructed to have the general appearance of the Goodyear welt shoe and is much cheaper to manufacture but is not durable, and not capable of re eated repair because if resewn the insole is cut b the needle and thread. Furthermore, MZKay shoes are not as comfortable to wear because they are stiff and rigid and the interior of the shoe is not left in a perfectly smooth condition. The chief reason why the McKay shoe is not durable is because the outsole is stitched to the upper and insole by a chain stitch located within the shoe, and the seam is of such a character that as the shoe is worn, the threads composing the stitches are cut off and the repeated bendin of the sole to which the shoe is subjected when worn, soon pulls the ends of the thread through the outsole so that the shoe goes to pieces. This is due in part to the fact that a needle which is large in relation to the thread must be employed in makinga chain stitch. In repairing the shoe, the new outsoleis usually nailed over the old one, but the weakness due to the fact that the ends of the thread have been cut ofl. is still inherent in the shoe, unless the nails are clinched on the inside. The use of nails is of course very ohjectionable. The. chief cause of the stiffness ofMcKay shoes is the chain stitch which always renders the shoe less flexible than a lock-stitch seam.

My invention, therefore, consists in securing together the parts of a shoe constructed like a McKay shoe with a through and through lock stitch seam formed with two threads. the locks of the stitches being located in the outsole so that when the shut tle thread is worn ofi',.the sole is stiil held to the insole and upper by means of the cop thread. In this way a shoe can be manufactured at a saving of expense amount-in to from to cents per pair, which will 0 osc ly approximate in durability a Goodyear welt shoe and which can be re eatedly repaired, because the stitching d oes not out the insole to pieces sufficiently to prevent resewing. A s ecific form of m invention also consists 1n stitching a hal soled shoe with a lock-stitch machine along the rear edge of the half sole.

The invention will be fully understood from the'following description when taken in connection with the accom "anying drawings, and the novel features t ereof will. be

pointed out and clearly defined in the claims at the close of. this s ecification.

In the drawings ig. 1 is a bottom plan view of the toe end of a shoe embodying my invention.

Fig. 2 is a section on line 2-2.

Fig. 3 is a section taken longitudinally of the seam.

In Figures 2 and '3, the parts are exaggerated-and distorted for clearness of illustration.

Referring now to the drawings, at 1 is shown the outsole of the shoe, at 2 a half sole, at 3 the insole, and at 4 the upper. The half sole of the shoe is grooved or scratched in the usual way, as shown at 15,

the shoe will pull'f'ii to assist in setting the stitch below the surface. The stitching 7 is formed with an uipper or cop three and e 10 or or shutt e 6,'and theitwqtliree are interwoven with each o'therigto v form a lock stitch. Thestitchee drown down with tension suflicient to the lock 8 well below the-surface fsole if there is one, or of the outso'lggf no he f sole is employed so thetjthe worn through withoutd v (V g ,.;'f.The-shoe shown in the drawings is sostttdhed with a lockstitching the rear of the he! et 9,"to take t e, lace of the r-.

The results attained by the herein described simple change in construction of the McKa shoe are veryremarkeble, both in the r ueed cost of manufacture .d the improvement in the quality of the es which 1. The herein described shoe havin an insole, an outsole and an upper secure toether by a through-an through, twothreed, lock-stitch seam located inside the s cc.

2. The herein described shoe havin an insole, an ou'tsole, and an. upper wit an inturned e'dge interposed between the edges 'all secured to "stint t. parts or of said insole and outsole, said parts being ether by a through-andthrough, two-t ead, lock-stitch seam located inside the shoe.

3. The herein described shoe having an insole, an outsole, and an upper secured together by a through-and-through, two thread, lock-stitch seam located inside the shoe and the thread locks of which are located within the outer surfaoe of said out- 4. The herein described shoe having an insole, an outsole, and an upper, the edge f portions of all of said parts being secured together .substantially throughout their lengths about the forepart of the shoe by a through-and-through, twwthread, 'lhckstitch seam located inside the shoe.

5. The herein described shoe having an insole, en outsole, and an upper with an in; turned edge interposed between the edges of sei'id insole and outsole, the edges of all of said parts being secured together substentiall'y throughout their lengths about the forepart of the shoes. by a through-andthrough, two-thread, ldck-stitch seam located inside the shoe and the thread locks of which are located within the outer surface of said outsole.

In testimony whereof I'aiiix my signature,

JAMES H. REED.
