J., acorporation of New_Jersey - Application DecemberïS, 1936, Serial No. 114,036 2 Claims.,-r (Cl. 12-142) cut-out piece has been sewed in place and the This invention relates to a method‘of making shoes and to an insole which is employed in prac ticing the method. In the manufacture of one type of shoe the 5 bottom of the forepart of which is flexible, it channel flaps have been raised to form a rib; Fig. 8 is a transverse section of Fig. 7; Fig. 9 is a transverse section like Fig. 8 but showing in additiona reenforcement of sheet 5 material cemented to the insole; Fig. 10 is a detail showing the lasting of the upper and the fastening of it to the rib of the has been customary to provide a skeletonized in sole having an opening in its forepart into which a projection on the outsole extends, and one ob ject of the present invention is to improve the 10 method of manufacturing such a shoe. Not only is it difficult to attach a skeleton insole firmly to the bottom of a last but, when this insole is cated shoe after the inseam has been trimmed and the cut-out piece removed; subjected to strains as it is, for example during the lasting of the upper, it is liable to be 15 stretched or distorted, with the result that the desired shape of the finished shoe is not at tained. According to the present invention, a piece is out out of the insole to produce an opening hav 20 ing a beveled edge in its forepart in which the projection on the outsole may later be received, and then the cut-out piece is fastened firmly but projection on its forepart; Fig. 13 is a transverse section through the fore part of the outsole; Fig. 14 is a transverse section through the fore part of a finished shoe; and Fig. 15 is a view partially in transverse section and partially in perspective showing the interior 20 of the toe portion of a finished shoe. In carrying out the method, an insole (Fig. l) detachably in place with the beveled edge of the piece in contact with the beveled edge of the 25 opening. This insole, which is practically as is channeled, for example by making the two cuts 2|, 23 commonly employed which produce two thin flaps. A piece l I9 is cut out of the fore strong as before the opening in it was made, is assembled together with an upper upon a last, and the manufacture of the shoe is carried out in any desired manner until the partly fabricated 30 shoe reaches the stage where the outsole is to be part of the insole to provide an opening to re ceive the projection |25 (Fig. 12) on the outsole 25. This projection may be formed in any suit able manner and preferably has a beveled edge 225. Returning to Figs. 2 to 10, a satisfactory 30 mode of cutting out a piece from the insole is by distorting the forepart of the insole and feed ing it to a knife 28 by means of rolls 21, 29 having respectively a matrix 3l and a patrix 33, these members being properly shaped and ar attached, whereupon the cut-out piece is re-' moved from the opening in the insole, and the outsole is fastened in place with its projection extending into the opening. Althoughthepresent 35 invention is applicable to the manufacture of vari ’ous kinds of shoes having skeletonized insoles, it is particularly well adapted to the manufacture of a Goodyear welt shoe. Referring to the accompanying drawings: 40 Fig. l is a perspective of a channeled insole; Fig. 2 is a transverse section of this insole; Fig. 3 is a detail in end elevation of a portion of a machine for distorting the insole and cutting the piece out of the forepart, an insole being shown in process of being operated upon; Fig. 4 is a detail in front elevation of a por tion of the same machine and insole, the cut of the knife being indicated by a dot-and-dash line; 50 Fig. 5 is a transverse section of the insole show ing the bevel edge of the cut~out piece and that of the opening; Fig. 6 is a perspective of the insole after the cut-out piece has been severed therefrom; 55 Fig. 7 is a perspective of the insole after the insole by a staple lasting machine; Fig. 11 is a transverse section of a partly fabri Fig. 12 is a perspective of an outsole having a ranged to cooperate with each other so as prefer ably to provide a beveled edge opening into which the projection 125 on the outsole will fit. The cut-out piece IIS is now detachably fastened in place in the opening so that, at the proper time, it may readily be removed. As illustrated, the piece is sewed in place by chain stitches 35 which pass through the beveled edges of the cut-out piece and of the opening and which may readily be pulled out. The channel flaps are now raised and stuck.together in the usual manner to form a rib 31, the completed insole having the appear ance shown in Fig. '7. It will be noted that the bevel cut by which the piece H9 was cut out is inclined downward and inward from the sole 50 attaching face of the insole so that later this piece may readily be removed from that face. The completed insole is assembled together With an upper, which ordinarily comprises an outer layer 39 and a lining 4I, upon a last 43 and 55 2,124,653 is lasted in any desired manner and fastened to the insole. As illustrated in Fig. 10, this may be accomplished by means of a suitable lasting ma chine which drives staples 45 through the upper into the rib 31. The welt 41 (Fig. 11) is attached by a Welt sewing machine which inserts the stitches 49, and the inseam is trimmed. At this stage, the chain stitch 35 (Fig. 7) which holds the cut-out piece H9 in place is pulled out and the 10 piece is removed, the shoe now having the ap pearance shown in Fig. 11. The outsole 25 is located on the bottom of the shoe with its pro jection |25 extending into the opening in the in sole, with the beveled edge of the projection 15 against the beveled edge of the opening, and is pressed ñrmly into place bythe usual sole-attach ing machine, after which the sole is fastened to the welt by stitches 5l and the sole is leveled. ~ Referring now to Fig. 9, the insole of Fig. 8 20 may be reenforced if desired by a properly shaped piece of sheet material 53, such as canvas or leather, which is cemented to one face of the in sole I9 and to the inner face of the rib 31 over the cut-out piece l I9; and in this- case it will be 25 necessary to cut this reenforcement to permit re moving the cut-out piece. If desired the point of a knife may be forced through the reenforcement and into the cut between the cut-out piece and the rest of the insole, and then the knife may be 30 manipulated to sever the stitches 36 and at the same time cut a piece out of the reenforcement. Although the invention has been set forth as applied to the manufacture of a welt shoe in which the sole is attached to the welt by stitches, 35 it should be understood that the invention is not limited in the scope of its application to use in the manufacture of such a shoe. And valthough the illustrated method has been described as com prising a series of steps performed in a particular order, it should be understood that the order of the steps may in some cases be varied. Having thus described my invention, what I claim as new and desire to secure by Letters Pat ent of the United States is: 1. The method of making a shoe which com prises providing an outsole with a beveled pro jection on its forepart, cutting a piece out of the forepart of an insole to produce an opening hav~ ing a beveled edge in which the projection on the outsole may later be received, detachably fasten ing the cut-out piece in place in the opening by means of stitches extending substantially par allel to the edge of the opening in the insole and capable of being readily pulled out, and employ 15 ing the insole and outsole in the manufacture of a shoe including removing the cut-out piece and fastening the outsole in place with its projection extending into the opening and the beveled edge of the projection in contact with the beveled edge of the opening. 2. The method of making a shoe which com prises providing an outsole with a projection on its forepart, channeling an insole, cutting a bev eled edge piece out of the fcrepart of the insole to 25 form an opening to receive the projection on the outsole, detachably fastening the cut-out piece in the opening by stitches which pass through the k beveled edge of the cut-out piece and that of the opening, raising the channel flaps to form a rib, 30 attaching a reenforcing fabric to the insole over the cut-out piece and employing the insole and outsole in the manufacture of a shoe including cutting out a portion of the reenforcing fabric, severing the stitches, removing the cut-out piece 35 and the cut-out portion and fastening the out sole in place with its projection extending into the opening.
