SHOE WELTING.

Application filed March 3, 1928. Serial No. 258,848.

This invention relates to the manufacture of two-unit shoe welting and more particu- 1 tion is to provide an upper unit that will cushion on itself and cause it to conform to the welt crease an'd fit snugly against theupper regardless ofvariations in the dimension or form of the crease.

To the accomplishment of this object the invention comprises shoe welting having the novel feature hereinafter described and then particularly pointed out in the appended claims.

The preferred form of the invention is illustrated by the accompanying drawing, in which all the figures are shown in perspective,

Figure 1 showing two strips of sheet material superposed and united for the first step in producing the upper unit;

Fig. 2 showing the two strips oppositely folded to form-a double beaded shoulder;

Fig. 3 showing the free margins cementedA together to complete the upper unit;

Fig. 4 showing a modification in which a filler or core is inserted within one of the folds;

Fig. 5 showing a complete two unit welt having the self-cushioning upper unit; and Fig. 6 showing the preferred welt of this irlllvention sewed in position on a portion of a s ce.

In the embodiment of the invention illustrated in the drawing the first stage of manufacture consists in laying face to face two stripes 10 and 12 of flexible sheet material, preferably upper leather or the like, each strip having a finished face and these faces being in contact. These two strips are then secured together at'one margin as by the dry thread seam 14 (see Fig. 1). The second step consists in folding each strip longitudinally (see Fig. 2) over and under the seam 14 to form two superposed beads 16 and 18 each presenting the finished face of the strip. The free margins of the two strips may then be cemented or otherwise fixed together (see Fig. 3) in order to complete a'double beaded upper unit which can be handled and sold as a unitary article separate from the lower unit with which it will later be assembled by the shoe manufacturer.

When the complete welt, both upperand lower units, are sold as a unitary article the folded upper unit of Fig. 2 may be stitched through its inner margin by a dry thread seam 20 (see Fig. 5) to the inner margin of the lower unit or body member 22, conveni- .en'tly and usually a strip of regular Goodyear welting.

If found to be desirable a filler or core 24 of leather, or any other suitable material, may be fed within one of the folds 16 or 18 (shown within the lower fold in Fig. 4) to give additional body to the shoulder formed by the double bead.

In using either form of the upper unit, on sewing the inseam 26 (Fig. 6) which secures the upper unit in lace when it is fed separately to the stitchorming mechanism, the thread tension mechanism draws the welt inward and seats the duplex bead of the upper unit snugly in the crease. The natural tendency of the folds to expand causes the bead to closely hug the upper 28. Neither welt beating or sewing the outsole 30 tends to draw the flexible yieldable double bead out of position. The bead, either with or without a filler 24 is sufficiently flexible to act as a cushion that will conform to inequalities of the crease and thus add to the quality of the shoemaking and enhance the style of the shoe.

The nature and scope of the invention having been indicated and its preferred embodiment having been described, what is claimed as new, is

1. An upper unit for two unit shoe weltlng comprising two strips of flexible sheetmaterial heldin a superposed relation by a secureeoI ment along one margin, said marginal material being oppositel folded about the securement to form a ouble bead, and the two free margins being fixed together beside sald folds.

2. An upper unit for two un1t shoe welting comprising two strips of fiexible sheetv 'two free margins 'being'ixed together beside said folds, at least one of said beads being reinforced by a core piece within the fold.

3. Two unit shoe Welting comprising a body member, and an independently formed upper unit secured to the linner margin of said body member consisting of two strips of iexible material oppositely folded to produce an outwardly facing shoulder presenting a duplex longitudinal bead on the exposed face of said body member.

4. The method of making an upper unit, having a double bead, for two unit shoe welting which consists in laying two stripsof flexible sheet material face to face, securing said strips along one margin, folding said strips longitudinally over and under said securement and ixin together the free margins beside said fol S.

5. A Welt shoe having a Welt stitched to the upper and insole, an outsole stitched to said Welt, and a bead member on theexposed face of the welt composed of Hexible sheet material havinga duplex fold located in the crease of the shoe, said fold having the property of yielding and cushioning on itself to fill inequalities in the crease.
