METHOD OF MAKING SHOES.

Application filed March 11, 1918, Serial No. 221,586. Renewed February 12, 1923 To all whom 2'25 may concern:

Be it known that I, LAURENCE. E. Tor HAM, a citizen of the United States, residin O at Swampscott, in the county of Essex and 5 State of Massachusetts, have invented certain new and useful Improvements in Methods of Making Shoes; and I do hereby de-' inseam, which begins at the breast line on one side and terminates at the breast line on the other side of the sole. The inseam may be sewed by hand, but is usually sewed on an inseam sewing machine. At the be 'nning of the inseam, a free end of the welt is held by the operator or by a welt holderuntil after the initial stitchesof the seam have been sewed, and at the comple tion of the inseam the welt is severed by the operator or by a welt cutter to leav a free end of welt at this end of the seam. The free ends of the welt are subsequently beveled off or butted by hand or by machines specially constructed for this operation. This method of butting the welt ends requires the services of a skilled operator, or additional equipment in the form of a welt butting machine, and usually results in more or lesswaste of the welting, due to the unequal or'surplus length of the free ends.

The present invention eliminates the usual operation of butting the free ends of the welt after it has been attached to the shoe, thereby reducing the skilled labor and equipment requiredl'and also avoids the waste of welting incident to the usual methods of manufacture. This is transversely skiving the welt after the welt has been partially attached, in such manner andat such a point that upon severing the welt at the completion of the attaching operation a properly beveled or butted free end will be left at. the end of the attached welt, and a proper bevel will also be left on the end of the welting for attachment to the sucaccomplished by ceeding shoe, The transverse skiving should form a depression having gradually sloping sides which converge and pass nearly through the welting midway of the skiving, and it should be so located in the welting that it will be at the end of the welt attaching seam when the seam is completed. 7 When i the welt is severed midway of the skiving, one of the sloping sides will form a proper bevel at the free end of the attached welt, while; the other sloping side will form a bevel at the end of the welting which is to become the free end of the weltat the beginning of the next attachingoperation.

The invention is illustrated in the accom panyi-ng drawing, in which Figure lqis a. diagrammatic view showinga'welt attach ing inseam partially sewn and the .welt transversely skived,.and Fig. 2 is a view showing the end of the inseam and attached welt. I In practicing the present invention as illustrated in the drawing the inseam may be sewed in the usual manner, say by hand or upon an inseam sewing machine in which 7 I the shoe'is manipulated by the operator or automatically. After the inseam is partially sewed, the welt is transversely skived, as indicated at 2. Itis desirable thatthe' inseam be nearly completed before the welt is skived, since inaccuracy in its final location due to stretch of the welt is thusavoid ed. The skiving is done at the point in the welting corresponding to the welt end when the inseam is completed andtheweltsev- I ered at the proper distance from the end of the seam. The skiving may be conveniently) and accurately-done by asuitable skiving: knife arranged to be passed across the welting by the operator or by automatically operating mechanism when the proper point in. the sewing of the inseam is reached, The skiving knife should be arranged to form a transverse depression deep enough to nearly sever thew'elt, and having gradually sloping'sid'es 4e and 6 which converge towards the center of the skiving, A slit 8' is preferably cut midway of the skiving which extends from the inner edgev partially. across the w'elting. This enables the weltin to be severed after the inseam is finishe "with less danger of injury to the upper.

When the inseam is completed it will end at the beginning of the SlOPing surface 4:, as

indicated in Fig. 2, and after the welt is severed midway of the depression 2 this surface will correspond to the bevel formed on the free end of the welt by the usual welt butting operation. The sloping surface 6 which is left at the end of the welting may be so located at the beginning of the succeeding inseam that it will correspond to the bevel formed on this end of the welt by the usual welt butting operation. When the attachment of this welt by the inseam is completed, therefore. the ends of the welt will be properly beveled for the attachment of the outsole without any further manipulation. or subsequent operation. The beveling or butting of the welt ends may also be accomplished without waste of welting, and in case the sewing of the inseam is done on an automatic machine without interrupting the sewing of the inseam.

,Vhat is claimed is:

1. An improvement in the art of making shoes which consists in transversely skiving the welt after the inseam is partially sewed to form a bevel surface ata point corresponding to the welt end of the finally attached welt,. completing the sewing of the inseam, and severing thewelt at the end of the beveled surface.

2. An improvement in the art of making shoes which consists in transversely skiving the welt after the inseam has been partially sewed to form oppositely sloping surfaces which pass nearly through the welt at a point corresponding to the welt end of the finally attached welt, completing the sewing of the inseam and severing the weltmidway of. the skiving.

3. An improvement in the art of making shoes whichconsists in partially sewing the inseam, transversely skiving the welt at a point corresponding to the welt end of the finally attached welt, cutting a slit midway of, the skiving from the inner edge part wa across thewelt, and completing the sewing of the inseam and the severing of the welt.

it. An improvement in the art of making shoes which consists in transversely slriving the welt from edge to edge to form oppositely beveled welt ends when the welt is severed midway the slriving.

5. An improvement in the art of making shoes which consists in cutting in the welt during the sewing of the inseam a transverse depression having oppositely sloping surfaces to provide a butted end for the welt being attached and a butted welt endfor attachment to the succeeding shoe upon severing the welt between the surfaces.

v An improvement in the art of making shoes which consists in producing in a welt .a recess extending from edge to edge and having oppositely inclined sides arranged to. form beveled surfaces at the ends of.

the respective portions of the welt on each severed in the side of the recess when the welt is substantially at the central point recess.

7. An improvement in the art of making shoes which consists in producing in a welt a recess extending from edge to edge and having oppositely inclined sides, and seven ing the welt at substantially the (entral point in the recess.

8. An improvement in theart of making shoes which consists in forming in a welt, at a single operation, an inclined cut extending from edge to edge to form a beveled surface at one end of the portion of the welt to be attached to one shoe, and an oppositely inclined cut extending from edge to edge to form a beveled surface at the opposite end of another portion of the welt to be attached to another shoe.

9. An improvement in the art of making shoes which consists in attaching one end of the welt to a shoe and before the attaching operation is completed making an inclined cut partially through the welt to form a beveled surface atthe end of the welt attached to the sho completing the attaching operation, and severing the welt.
