Claims. (Cl. 36-115) This invention relates to improvements in insoles and more particularly to insoles for use in strap sandals and other shoes the uppers of which comprise portions which are spaced apart lengthwise of the shoe and are inturned between inner and outer soles. The invention relates also to improvements in the construction of sandals and similar shoes.
In the manufacture of sandals it is a common practice to attach the outsoles by means of cement. In some instances the pressure exerted upon the shoe bottom in the outsole cement attaching press is insufiicient to force the margin of the outsole into intimate engagement with the insole in the areas between the inturned ends of the straps and consequently the outsole is improperly attached or is left unattached to the insole in those localities. Such a condition is undesirable not only from the standpoint of securing reliability of attachment of the outsole but also because of the presence of narrow openings between edge portions of the soles in the localities between the straps which impart an unfinished appearance to the shoe.
In other instances, while the marginal portions of the inner and outer soles are cemented together, nevertheless, small gaps are invariably formed between the soles at points immediately adjacent to the opposite edges of the inturned end portions of the straps where the thickness of the strap material renders it practically impossible for the soles to be forced into intimate contact. These small gaps are quite conspicuous and detract from the appearance of the shoe.
One object of the present invention is to avoid such undesirable conditions as those above mentioned and to insure intimate contact of the edge portions of the inner and outer soles in the spaces between the straps including the localities immediately adjacent to the opposite edges of the inturned ends of the straps or other spaced upper members.
To this end the invention, in one aspect, con sists in an insole having a bead extending along its edge at that side of the insole which is to face the outsole, the bead comprising resilient compressible fibrous material supported by a portion of the insole and covered by a binding strip secured to the marginal portion of the insole. The bead is adapted to be compressed in those portions where the straps of the upper are overlasted upon the insole to enable the straps to sink into and become embedded in depressions in the bead while, in each of the spaces between the straps,
the bead will remain upstanding and uncompressed throughout the full width of that space so that there will be no unsightly gaps between the margins of the inner and outer soles near the edges of the straps.
Invention is also to be recognized as residing in certain features of shoe construction hereinafter described and claimed.
The invention will be explained with reference to theaccompanying drawings, in which Fig. l is a plan view of a machine for folding an edge binding strip and applying the strip to an insole. In this figure an insole is shown in process of having an edge binding applied thereto 'and having a padding strip applied between the edge binding and the insole at one side of the shoe;
Fig. 2 is a perspective view of the edge binding folding device shown in Fig. 1;
Fig. 3 is a perspective view of an insole to which an edge binding and a padding strip have been applied in accordance with the present invention;
Fig. 4 is a fragmentary cross-sectional view on an enlarged scale taken along the line IV-IV of Fig. 3;
Fig. 5 is a view similar to Fig. 4, but illustrating the attachment of the edge binding strip to the insole by means of cement;
Fig. 6 is a perspective view of a strap sandal embodying my improved insole, the shoe being shown as it appears before the outsole has been applied? Fig. 7 is a fragmentary view in side elevation of the sandal as it appears after it has been completed;
Fig. 8 is a cross-sectional view'of the forepart of the sandal on an enlarged scale, the section being'taken between two of the straps;
Fig. 9 is a view similar to Fig. 8, except that the section is taken through one of the straps; and
Fig. 10 is alongitudinal sectional view taken in a plane indicated by the line X-X of Fig. 8.
The shoe shown in Figs. 6 to 10, inclusive, of the drawings is a strap sandal the upper of which comprises a forepart consisting of a plurality of cross-straps I4, and a rear part or quarter l6 which is spaced from the forepart. The sandal comprises also an insole I8 and an outsole 20.
The insole I8 is provided with an edge binding 22 consisting of a strip of binding material which is folded over the marginal portion of the insole and which may be secured in place by means of stitching, as indicated at 24, or by means of cement, as indicated at 26 in Fig. 5. The edge binding 22 provides a finished display surface for the edge of the insole where the insole is exposed to view in localities between the straps and along the open shank portion of the shoe.
The insole is is further provided with a compressible padding strip 28 which extends along the marginal portion of the insole at the lower side of the latter, i. e., the side which is to face the outsole. The padding strip 28 is made of resilient cushioning material and it may consist, for example, of a string of loosely twisted yarn. As herein shown, the yarn or padding strip 23 is interposed between the insole and the strip of material which constitutes the edge binding 22 and is held in place by the binding strip. While this arrangement of the padding strip is not essential, it is preferred inasmuch as the binding strip serves to cover the padding strip, although the latter is enabled to function in substantially the same manner as if it were exposed. The binding strip, however, furnishes a finished surface which presents a neat and ornamental appearance and one which is continuous with that which covers the edge face of the insole.
As indicated in Fig. 1, the edge binding may conveniently be supplied as an unfolded strip and progressively folded and applied about the edge of an insole by a sewing machine provided with a suitable folder through which the binding strip is drawn. Any suitable sewing machine may be employed, the throat plate of the illustrated machine being indicated at 30, the presser foot at 32, and the needle at 34. The folder 35, a perspective view of which is shown in Fig. 2, is so formed that when a binding strip is drawn through it the strip is progressively bent or folded into a U-shape such as to fit about the edge and over both marginal faces of the insole. A padding strip supplied in the form of a string of yarn or the like is introduced beneath that portion of the binding strip which is to overlie the outsole-facing side of the insole. The binding strip, together with the padding strip, passes progressively beneath the presser foot 32 (which is shaped to accommodate the bulge of the padding strip) and the binding strip is stitched to the insole, as shown, the stitches 24 assisting in holding the padding strip in place as well as securing the binding strip to the insole. At the completion of the operation of applying the edge binding and the padding strip to the insole, the insole appears as best shown in Fig. 3, wherein it will be seen that the padding strip provides a compressible bead which extends continuously about the margin of the insole except at the heel end of the insole.
Referring now more particularly to Figs. 6 to 9, inclusive, the insole I8 is assembled with the parts of the upper upon a last 40. The lower margin of the quarter or back part 16 is lasted over upon the heel seat of the insole and is secured in place by means of tacks 42. The crossstraps l4 constituting the forepart of the upper are lasted over upon the forepart of the insole and fastened by means of staples 44. As indicated in Fig. 6, thetension which is exerted upon the straps during the lasting operation is ordinarily sufiicient to cause the marginal bead formed by the padding strip to become compressed beneath the straps so that the latter will become embedded in depressions in the bead. The overlasted portions of thestraps are trimmed and roughed in the usual manner, a shank stiffener 46 is secured in place upon the insole, and a, suitable filler piece 48 is applied to the central portion of the forepart of the insole. A coating 5,01 Qf a. sui ab e adhesive, such-as py ozs lin ment, is applied along the margin of the bottom of the shoe throughout the shank and forepart, i. e., to the overlasted end portions of the straps and to the marginal portion of the insole in the localities between the straps and along the openshank portion of the shoe bottom. A previously applied coating of dry cement on the margin of the shank and the forepart of the outsole is activated, the outsole is properly located upon the bottom of the shoe, and the shoe and outsole are put in a press and subjected to pressure in the usual manner. After a suflicient interval of time has elapsed, the shoe is removed from the press. The heel seat of the outsole is then fitted and a wood heel 52 is attached. As shown, a sock lining 54 may be applied to the foot side of the insole.-
As a result of the outsole attaching pressure the overlasted ends of the straps I4 will become embedded even more deeply within the bead formed by the padded edge binding of the insole, the padding being compressed until it is Very thin and the binding itself stretching sufficiently so that depressions or pockets conforming to the crossesecticnal contour of the straps are formed therein as indicated at 56 in Fig. 10. Thus the outsole will be firmly secured by the cement to the overlasted end portions of the straps and to the beaded edge binding in the localities between the straps where the bead is not substantiall depressed and where the padding strip remains substantially uncompressed. The outsole will'also be secured by cement to the bound margin of the insole along the open-shank portion of the shoe. These uncompressed portions of the padded edge binding serve to fill in between the margins of the inner and outer soles in the localities between the straps. Because of the resilience of the padding strip the edge binding will closely overlie the opposite edges of the over lasted strap ends and prevent the formation of undesirable gaps between the edges of the straps and edg binding so that no openings are left at the edge of the shoe bottom in the corners 1 between the edges of the straps and the outsole. As a result there will be a continuous cement bond between the outsole margin and the margin of th shoe bottom and, as indicated in Fig. 7, the edge appearance of the shoe bottom will be unmarred by openings or gaps of any sort between the inner and outer soles in the 10- calities between the straps.
Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1, An insole having a bead extending along its edge at th side of the insole which is to face the outsole of a shoe, said bead comprising resilient compressible fibrous material supported by a portion of said insole and covered by a binding strip secured to the marginal portion of the insole.
