Claims. 1

This invention relates to improvements in the manufacture and construction of shoes, and more particularly to a shoe construction to facilitate the proper positioning of the upper of a shoe relative to the bottom thereof and at the same time provide an arrangement whereby the upper may be securely fastened to the bottom of the shoe.

In the manufacture of shoes the pre-cut upper of the shoe must be located very exactly relative to the bottom members of the shoeother wise a defective article results. In the manufacture of shoes, it is desirable to eliminate the use of a last or to render the lasting process less exacting; and to assist the operator in the assembling of shoes the prior art has suggested the arrangement wherein the lasting allowance of the upper is in the form of a plurality of tabs or tongue-like portions extending beyond the lower margin of the upper and a sole member is provided with a plurality of slots therethrough for the reception of the tabs, the tabs on the upper and slots in the sole member being selectively positioned so that when the various tabs on the upper are pulled through the corresponding slots in the sole, the upper is properly located relative to the sole, andthe parts are ready for the next step in the manufacturing process.

However, such shoe constructions have been limited to the manufacture of various types of inexpensive shoes for the reason that when-the tabs on the upper are spaced from one another, and the tabs are pulled through the slots until the lower edge of the upper engages the upper surface of the sole, the lower margin of the upper between the tabs is visible from the outside of the shoe, and the said lower margin being unsupported is free. to. move relative to the slotted sole member. When the tabs are formed con tinuously along the lower margin of the upper, the. upper ends; of, the tabs and the upper ends of the cuts between the tabs are visible from the outside of the shoe.

Another disadvantage of such shoe constructions is that in view of the limited area of the tabs. and their spaced locations, it has been difficult to fasten the tabs to the sole of the shoe so as to. retain the upper in the proper position relative tothe sole. throughout thelife of the shoe.

The objects, of this invention are two-fold in nature: first, in conjunction with-shoes of the type mentioned to provide means whereby the lower margin of. the upper and the upper ends of the tabs; may becovered, at thesame: time iving to the shoe a conventional appearance; andseoond, to arrange and attach the tabs as well as the covering means relative to the upper and sole members so that the lower margin of the upper will beheld againstmovement and the-upper will be securely fastened to the sole members in the normal course of completing the manufactured the shoe, whereby a. strong construction may be economically produced.

One of the objects of this invention is accomplished by providing a strip attached to at least one of the other shoe elements and extending along the outer lower margin of the upper to cover the same. This strip may take the form of a welt of the usual type, or it maybe of the prewelt form. When appliedto a shoe of the platform type, the strip is in the form of a platform cover.

The invention also contemplates, in part, the turning outwardly of some of the tabs on the upper, in which case stitching may be passed through the welt, outturned tabs and outer margins of the inner and outer sole members to obtain a strong attachmentof. the upper to the bottom shoe parts.

A'slip sole may be inserted inside the shoe to give the interior thereof a usual appearance, and the upper may be attached to the slotted sole member with or without the aid of a last.

Other features of this invention will be disclosed in the ensuing description of the constructions shown in the various drawings, in which,

Fig. l is an exploded perspective view of an upper with a lasting allowance in the form of a plurality of spaced tabs, together with an inner sole member having a plurality of slots passing therethrough near the edge of the member for the reception of the tabs;

Fig. 2is a perspective view of a portion of a shoe embodying the construction of Fig. 1, certain parts thereof being broken away to disclose the position of the tabs relative to the inner and outer .sole members of the shoe, together with a conventional welt placed around the outer lower margin of the upper.

Fig. 7 is a cross-sectional view of one construction of a shoe embodying the construction shown in Fig. 6;

Figs. 8 and 9 are perspective views of the outside and inside, respectively, of a shoe embodying the construction of Fig. '7, certain parts being broken away for the purpose of illustration;

Fig. 10 is a fragmentary cross-sectional View of a shoe embodying the tab arrangement shown in Fig. 7, employed in conjunction with a shoe having a welt with an upstanding flange;

Fig. 11 shows the same construction as Fig. 7 with the addition of a slip sole inside the upper; and

Fig. 12 shows an arrangement like Fig. 7 except the outturned tabs extend only part way to the outer edge of the inner sole member, the under side of the welt being tapered in cross section.

Reference is now made to Fig. 1, which discloses the first form of my invention wherein the lasting allowance of the upper 20 is in the form of a plurality of spaced tabs 22, the lower edge of the upper between the tabs 22 being numbered 24.

The outermargin of the inner sole member 28 is provided with a plurality of slots 36 separated by surfaces 32, the slots 38 being of a length corresponding to the width of the tabs 22 and of a width corresponding to the thickness of the tabs 22. The tabs 22, in the case illustrated, all line forward of the breast of the heel, and the upper to the rear of the breast of the heel is provided with the usual lasting allowance 26. However, if desired, the upper to the rear of the breast of the heel may be provided with tabs like the tabs 22, and the corresponding part of the member 28 may be provided with slots like the slots 30 to receive such tabs. More generally, the tab and slot arrangement disclosed herein can be employed on any portion of the shoe, the remaining portion of the upper being fastened to the bottom of the shoe by any conventional method.

By properly precutting the upper 20 and tabs 22 and positioning the slots 30 in the inner sole member 28, it. will be appreciated that the upper 2|] may be correctly positioned relative to the member 28 by inserting each of the tabs 22 in its corresponding slot 30, and drawing the tabs through the slots until the edge 24 of the upper engages the surfaces 32 on the upper side of the inner sole member which lie between the slots 32.

In Figs. 2 and 3 it will be seen that the tabs 22 pass through the slots 30 in the member 28, the tabs being pulled through the slots so that the edges 24 of the upper 2!] intermediate the tabs bear against the surfaces 32 on the upper side of the inner sole member 28 intermediate the slots 30 in the same. The lower ends of the tabs 22 are turned inwardly to lie against the bottom surface of the member 28 and are suitably attached thereto, as by an adhesive. The outer sole member 34 underlies the inner sole member 28 and covers the lower inturned ends of the tabs 22, and a strip of covering material in the form of the welt 36 which is of a width equal to the width of the marginal portion of the inner sole member 28 lying outside the lower edge 22 of the upper 20 overlies the upper surface of the inner sole member outside the edge 24, the inner surface of the welt abutting against the outside lower portion of the upper 20 above inner sole member 28 and covering the said edge 24 and ones the outside lower portion of the upper above the edge. The welt 36, inner sole member 28 and outer sole member 34 are held together, as by stitching 38.

Fig. 4 is a fragmentary cross-sectional view of a shoe 0f the prewelt type incorporating the first form of my invention, the construction of which is like that shown in Figs. 1, 2 and 3 with the exception that in the manufacture of such a shoe the surface 39 of Welt 40 is laid against the outer surface of the upper 26 with the lower edge 42 of the welt along the edge 24 of the upper and the other edge 43 of the welt along the upper above the edge 22. The welt and upper are then stitched together by stitches 46, and the tabs 22 pulled through the slots 38 in the inner sole member 28 until the lower edge 24 of the upper and lower edge 42 of the welt respectively engage the surfaces 32 between slots 30 of the member 28 and the outer margin of the upper surface of the inner sole member. The tabs are then turned inwardly under the inner sole member and secured thereto, as previously explained, and the outer sole member 34 is applied to the bottom of the inner sole member 23. The portion of welt 40 above the stitching 46 is then turned away from the upper to place the surface 43 thereof against the upper surface of the outer margin of the inner sole member 28, and the welt, innersole and outer sole member secured together by stitching 38.

Fig. 5 is a fragmentary cross-sectional view of a shoe incorporating the first form of my invention and which is like the arrangement described in connection with Fig. 4 except that the cover 50 is employed in place of the welt, the cover being stitched to the upper 20 by stitches 46. After the cover 50 is so stitched to the upper and the tabs 22 passed through the slots 30 in the inner sole member 28 and bent inwardly thereunder and secured to the bottom of the same, the free portion 52 of the cover is wrapped around the peripheral edge of the member 28 and turned in under the bottom surface thereof covering the lower in-turned ends of the tabs 22. The inner surface of the cover 52 is suitably attached to the contacted surfaces, of the inner sole member 28 and tabs 22, as by an adhesive. The outer sole member 34 is then applied to the bottom of the shoe by adhesive or any other desired fastening means.

It will be understood that the form of my invention shown in Figs, 1-5 including spaced tabs formed with the upper and the provision of slots in the inner sole member for the passing through of the tabs permits the proper positioning of the upper relative to the inner sole member without the necessity of performing the conventional lasting operations, and that the attaching of the in-turned ends of the tabs to the bottom of the inner sole member holds the upper in proper position relative to the sole member, while the combined provision of a cover strip covering the outer lower margin of the upper gives to the shoe a conventional exterior appearance. In the arrangement of Figs. 4 and 5 where the cover strip takes the form of a prewelt or cover attached to the upper, the upper is additionally attached to the sole members by the prewelt or cover strip and stitching or adhesive, respectively, thereby securing a sturdy construction. If desired, as will be explained, a slip sole or the like may be added to the inside of the shoe to give the same a conventional interior appearance.

Reference is now made to Fig. 6' which is a perspective viewof an upper and inner sole member made in accordance with the second form of my invention. Thelasting allowance of the upper 20' is in the form of a plurality of tabscomprising two alternating

sets

60 and 60a, formed by making a plurality of vertical parallel cuts 62- in the lasting allowance of the upper, the cuts 62 being spaced according to the desired width of the tabs formed thereby. The

cuts 62 extend from the breast of the heel to the forward end of the upper, the usual lasting al lowance 26 being left at the heel. The inner sole member 23 is formed as previously described upper 20 are pulled through, the slots 30 in the inner sole member 28' and the inner ends'thereof are turned inwardly under the same and are attached thereto as previously explained. The other tabs 60a are turned outwardly and laid along the upper marginal portion of the inner sole member. It will be understood that selected tabs 60 are drawn through the slots 36 until the upper ends of the cuts 62 are just above the top surface of the inner sole member. The outer sole member 34 is then applied to the bottom of inner sole member 28, covering the inturned ends of tabs 66, and the welt 36 is then placed on top of the outer margin of the inner sole member and out-turned ends of tabs 60a, and the welt, out-turned ends of tabs 60a, the outer margin of member '28 and outer margin of outer sole member 3d are fastened together by stitching 38. If necessary, the ends of tabs 65a projecting beyond the periphery of welt 36 and member 28 are trimmed off. The welt 36 is of sufficient thickness so that its upper inner edge lies along the outer surface of upper 2!] above the upper ends of cuts 62 and conceals them. The tabs of this and the first form of the invention may be skived, if desired.

In Fig. 7 the reference character 6! designates a last which may be slipped inside the shoe at any desired stage in the process of manufacture, e.'g., preparatory to putting on the outer sole member 34, or even before the tabs on the upper are inserted in the slots of the inner sole member, should circumstance render the same advisable. The optional use of the last 6| also applies to the other illustrations contained herein.

Fig. shows the same structure as Figs. 6, '1, 8 and 9 with the exception that welt 64 has an upstanding flange 64a which bears against the outer surface of upper immediately above the upper surface of the inner sole member 28. The upstanding flange 66a is of sufficient height so that its upper inner edge lies along the outer surface of upper 2t above the ends of cuts 62 to conceal them. Fig. 11 illustrates the same arrangement of my invention as Figs. 6-9 with the addition of a slip sole G5 placed inside upper 20 and overlying the inner sole member 28, the edge face of the slip sole 5'5 bearing against the inside surface of upper and being of sufficient thickness so that its upper corner lies along the inner surface of upper 20 above the upper ends of cuts 62 to conceal them. This arrangement may also be applied to any of the other constructions disclosed herein.

Fig. 12 illustrates the construction shown in Fig. '7 with the exception that the out-turned tabs 681a do not extend all the way to the outer periphery of the inner sole member 28' and the welt 36 is somewhat tapered in cross-section on its under side to accommodate the out-turned tabs and allow, the outer lower edge of the welt to be drawn into continuous contact with the upper surface of member 28.

It will be understood that the form of my invention shown in Figs. 6 to 12 including tabs formed with the upper and the provision of slots in the inner sole member for the passing through of the selected tabs formed with the upper permits the proper positioning of the upper relative tothe inner sole member without the necessity of performing the usual lasting operations, while the combined provision of other tabs formed with the upper turned outwardly to overlie the upper surface of the inner sole member with a welt overlying the out-turned tabs and having its inner edge abutting the lower outside margin of the upper is highly advantageous in that the welt, out-turned tabs, outer margin of the inner sole member and outer margin of theouter sole member may all be fastened together by usual means such as stitching, thereby securely fastening together the various parts of the shoe. By virtue of the disclosed arrangement, the stitching is conventional in appearance and is located outside the upper 29 and the welt conceals the exterior upper ends of the cuts and tabs, thereby rendering the shoe conventional in exterior appearance. By passing the selected tabs through the slots in the inner sole member and securing the ends thereof to the bottom of the inner sole member, the upper is doubly fastened to the inner sole member to produce a sturdy construction. If desired, a slip sole or the like may be added to the interior of the shoe, as disclosed, thereby concealing the interior upper ends of the cuts and tabs, thus enhancing the appearance of the interior of the shoe.

In view of the preceding disclosure it will be appreciated that this invention discloses a shoe construction having an upper withtabs along the marginal edge thereof arranged to be inserted in slots in an inner sole member to permit accurate and quick locating of the upper relative to the inner sole member, together with covering means for rendering the shoe conventional in appearance, both interiorly and exteriorly, at the same time the covering means and tabs are arranged and attached relative to the other shoe parts so that by means of the tabs and other well-known fastening means the upper may be securely attached to the inner sole member and. other parts of the shoe.

It will be appreciated by those skilled in the art that certain changes may be made in the constructions disclosed without departing from the substance thereof as covered by the following claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
