(Cl. 36-78) This invention relates to a novel welting for use in welted shoes and to improvements in welted shoes realized from this novel welting.

Patented Feb. 23, 1965 Turning now to FIG. 3 a typical welted shoe construction is illustrated-and includes aninsole 15 to which is secured aflexible rib member 16 as in the usual shoe construction. The shoe upper 17 is lasted over the insole and therib member 16 in the'usual way, and the welting is then positioned over the upper 17 and is It is an object of this invention to provide a novel welting having characteristics which result in a better welted shoe. 1

It is also an object of this invention to provide a welted shoe in which better flexibility and a stronger shoe can be obtained.

A further object of the invention is to provide welting that is adapted for flat lasting and presents a greatly extended surface for cementing of the out-sole so as to avoid stitching the out-sole as in a Goodyear welted shoe.

welting is made in length and to a uniform dimension so that the incorporation thereof into shoes can result in improved construction and quality. An important characteristic of the improved welting is the extremely wide scarfed margin of flexible form so that it will not detract from the flexibleness of the shoe.

stitched in place by a line ofstitching 18 which is'located in thewelting groove 13 and extends through the upper and therib member 16. During the stitching operation thescarf edge 11 of the welting is bent at an angle to thepre-fudged edge 10 so that the Goodyear stitching machine may be utilized in the customary way to join the several parts. Upon completion of the stitching operation therib member 16, the upper 17 and thescarf edge 11 of the welting are then flat lasted to theinsole 15. step of the shoe construction thesurface 11b of thescarf edge 11 extends inwardly from the line of thestitching 18 so that there is a wide strip of material inwardly of the stitching line to receive suitable cement or adhesive by which the out-sole 19 may be secured to complete the shoe construction. The final assembly is shown in fragmentary sectional view in FIG. 4 in which a suitable adhesive orcement 20 has been applied to thesurfaces 10!) and 11b of the welting so that the out-sole 19 has a considerable cemented connection inwardly of thepre-fudged edge 10. Before the out-sole 19 is placed,filler material 21 is disposed in the more central area of the insole in order to compensate for the slight thickness of the several layers A preferred embodiment of this invention is disclosed in the accompanying drawing, wherein:

FIG. 1 is a perspective view of the welting of this invention;

FIG. 2 is an end view of the welting;

FIG. 3 is a fragmentary sectional view of the welting inseamed to an insole and upper; and

FIG. 4 is a fragmentary sectional view after inseaming and lasting.

Referring to the drawing, the improved welting is illustrated in FIG. 1, and as there shown comprises a strip or length of material of uniform texture, strength and dimensions which may be produced in a continuous of the welting process if desired. Specifically, the material may be either leather or plastic, and it is characterized by having a wheeled or'pre-fudgededge 10 and ascarf edge 11 separated on one side by ashoulder 12 and separated on the opposite side by agroove 13. Theshoulder 12 andgroove 13 are substantially opposite each other and are parallel with theouter margin 10a of the wheeled edge and theinner margin 11a of the scarf edge. Thescarf edge 11 is provided with a pluralityof spacedslashes 14 extending inwardly from theinner margin 11a so as to render the welting flexible in its horizontal plane as is viewed in FIG. 2 for permitting the welting to be con formed to the curvature of shoes.

In FIG. 2 there-is shown a sectional view of the welting and it is pointed out that theedge 11 is wider than theedge 10. In the manufacture of the welting it is preferred that the undersurfaces 10b and 11b of theedges 10 and use substantially flat and in the same plane. Theouter margin 10a of edge10 is relatively thin compared to sections thereof inwardly toward theshoulder 12. This is to provide for a thinner appearance in the welting once those portions of the shoe construction which lie inwardly of thepre-fudged edge 10 as will be apparent upon inspection of FIG. 4.

of material comprised by therib 16, the upper 17 and thescarf edge 11 of the welting;

The improved construction allows for a considerably flatter final contsruction of the several parts, and avoids the usual inseam trim step which is required of the ortho dox welted shoe having a rib member which is very stiff since it is not capable of being flat lasted. There is considerable economy possible in the improved shoe construction and an important improvement in the security of attachment of the out-sole 19 is a cemented construc-.

For example, thepre-fudged edge 10 was approximately eight-thirty-seconds of an inch wide, the scarf edge was approximately ten-thirty-seconds of an inch wide. Theshoulder 12 was made approximately one-sixteenth of an inch high and the overall thickness of the strip of material substantially at theshoulder 12 was, approximately sixthirty seconds of an inch. It is, of course, recognized that the welting may be useful in narrowervor wider strips, and in which casefthe foregoing dimensionspwould be proportionately reduced orincreased, It is also possible to utilize the improved welting material in thefusual brogue type shoe by having theouter margin 10a of the"pre-fudged edge 10 as thick or nearly as. thick as the more central section of the welting.

While the foregoing description refers to a preferred form of the improved welting and has described a welted shoe construction utilizing the same, it is understood that variations may come to mind after appreciating the advantages hereof, and it is the aim and object to include changes and variations within'the appended claim.
