SHOE` AND METHOD OF MAKING SAME Filed April 50, 1936 2 Sheets-Sheet 2 Patented June 22, 1937 SHOE AND METHOD OF MAKING SAME Harry L. Sutcliffe, Brooklyn, N. Y., assignor to The Del-Mac Shoe Process Corporation, New
York, N. Y.
Application April 30,
9 Claims.
My invention relates to shoes in which an integral marginal rib is formed on a sole member to facilitate attachment of the upper parts of the shoe to the sole. Such ribs are commonly found in welted shoes, the rib being defined by and between the roots of marginal lasting lips erected from the surface of the sole member, or between an edge shoulder or a lip and the leaf of a marginal stitch channel. inseams such ribs are commonly referred to as the between substance through which the stitching passes. When the upper parts of the shoe are secured in inseamed relation to such a. rib, a stiff marginal ridge is formed which greatly detracts from the Iiexible qualities of the shoe.
It is a principal object of my invention, therefore, to provide an improved shoe in which the inseam rib is transversely divided into a plurality of sections or segments to render the shoe more flexible.
During the lasting of the shoe it is necessary, however, that the inseam rib be maintained as rigidly as possible so that it will withstand the strain of the lasting operations. It is therefore a further object of my invention to provide an improved method whereby the inseam rib may be segmented after the upper parts have been assembled in lasted relation to the sole member.
Moreover, where the inseam ofthe shoe is secured by stitching, it is highly desirable to maintain the rigidity of the rib during the stitching operations in order that it will afford proper resistance to the penetration of the awl and the needle. Also, were the rib to be segmented before stitching of the inseam it might easily hap pen that some of the stitches would coincide with some of the slash cuts dividing the rib, thereby weakening the construction. To slash the rib after the inseam is sewn would imperil the stitching.
It is a further object of my invention, therefore, to provide an improved method in accordance with which the inseam rib of a stitched shoe may be slashed progressively between stitches as the inseam is sewn.` Other and further objects will appear from the following specification.
Referring to the drawings which form a part of this specification:
Figure l is a. cross sectional view illustrating 50 an upper tack-lasted to a. lip channeled insole,
the section being taken transversely of the ball portion of the shoe.
Figure 2 is a plan view of the shoe shown in 55 Figure 1 after a welt has been applied and the inseam has been sewn, the inseam rib being transversely slashed between stitches of the sewing thread at the ball portion.
Figure 3 is a perspective view, partly in section and on a larger scale, illustrating the manner In shoes having stitched 1936, Serial No. 77,103
in which the slash cuts may be formed progressively as the inseam is sewn.
Figure 4 is a cross section taken thru slash cuts at or about line 4-4 of Figure 2 and'further illustrates the manner of forming the slash cuts.
Figure 5 is a view partly in section and partly in perspective showing the formation of a progressively slashed seam in a shoe having a shouldered insole.
Figure 6 is a view taken on line B-G of Figure 5.
Figure 7 is a view similar to Figure 6 illustrating a slight modification in which the slash cuts extend obliquely to the surface of the insole.
Figure 8 is a sectional view of the shoe shown in Figures 1-4 after the inseam has been trimmed, the bottom ller` applied, and the outsole attached, the section being taken through a slash cut on the left and exposing a stitch on the right.
Figure 9 is a perspective view of the completed shoe transversely divided at the forepart to disclose the finished relationship of the parts.
The drawings are merely illustrative and disclose my invention as applied to welt shoes only. In making welt shoes it is usual to provide an insole such as I5 having an integral outer lip I6 and an inner lip or channel leaf Il which are erected from the flesh side of the insole forwardly of the heel seat and cemented together to form an integral lasting rib I8, the rib being reenforced by the margins of a layer of fabric I9.
The insole is then secured to a last and the upper 2| and its lining 22 are pulled over the last and secured in lasted relation to the insole as by staples or temporary lasting tacks 23-23 etc. After lasting the upper parts are sewn, t0- gether with a welt 25, to the marginal rib I8, the stitches of the sewing thread extending thru the welt, the upper parts, the inner and outer lips, and the fabric I9, any temporary tacks 23 being removed as the stitching progresses.
In accordance with my invention a plurality of transverse incisions or slash cuts 32--32 etc., are made thru the inner portion of the marginal seam comprising the lips I6 and I'I and the upstanding margin of the fabric I9 to reduce the stiffness of the shoe bottom at the ball portion. These slash cuts are preferably extended to a depth corresponding to the bottom of the inseam thread and may also extend thru the upper parts,
if desired. However, I prefer not to cut through the upper parts at the inseam although the sweep of the slashing blade 33 may pass thru the untrimmed surplus portions of the upper parts as shown.
I have found that it is undesirable to effect the slash cuts before the inseam is formed because the segmented portions of the inseam are then too weak properly to resist penetration by the awl and the needle and, unless the cuts are most carefully spaced and the stitching carefully gauged, the subsequently formed stitches may coincide with the slash "cuts, To form the slash cuts 32 after the inseam is sewn would be impractical because the pre-formed stitches would then be located directly in the path ofthe slashing blade.
Therefore, I have conceived that the slash cuts may be advantageously formed progressively as the inseam is sewn, a cut being made in advance of each stitch. The procedure followed is best` illustrated in Figures 3-7 in which a hand stitched seam is shown in the course of its formation. After completion of a stitch 35, an awl hole 36 is formed for the reception ,of the next stitch; a
' transverse slash cut is then made intermediate the stitch and the awl hole, whereupon the next stitch is formed, and so on entirely about the,
inseam or such parts thereof as may be desired. I have illustrated the slash cutsv as formed only at the margins of the ball portion of the shoe,
leaving the seam comparatively stiff throughout.
the shank and toe portions where great flexibility is neither necessary nor desirable..
From the foregoing it will be clear that the slashed portions of the inseam appear as a pluf ralityof segments or sections linked together in the machine sewn seam is formed. Attachments for a standard inseam stitching machine have been devised for this purpose by Edward Q uinn and form the subject matter of a separate application for patent now in preparation.
The shoe is completed in the usual manner. That is to say the surplus portions of the Welt, the rib and the upper parts are trimmed, ller material 40 is assembled, and an outsole Il is attached to the welt by an outer line of stitching 42. A heel 43 is applied, the last is removed, a sock lining 44 is assembled, and all otherI usual and necessary operations are performed.
My invention is applicable to all types of shoes having a ribbed sole member and Figure 5 illustrates the upper parts lasted and stitched, together with a Welt, to a shouldered and channeled insole l5', a slashed rib I8 being defined between the shouldered edge I6' and the inner face of a channel leaf Il. The slash cuts may be extended obliquely to the surface of the insole rather than perpendicular thereto, if desired, and are so illustrated at 32 in Figure '7. 'I'hey may also be formed to extendv transversely through the inseam rib at any desired angle, all such modifications being within the scope of my invention as hereafter claimed.
In all such cases it will be found that the transverse slash cuts or incisions, formed in accordance with the method above described, will greatly enhance the flexible qualities of the shoe without impairing its structural strength, shape holding or wearing qualities.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
