(01. 36-1945) 1 a cushioning element orv “platform” at the fore This invention pertains to the manufacture of footwear; particularly" to the manufacture- of shoes of’ the open-toe and/or‘ open-heel variety, and: especially to those made by» the iorce-lasting part of’ the shoe’; Fig. 5' is a side elevation of‘ the assembled‘ parts shown in Fig. 4; Fig, 6‘ is a perspective view, showing the shoe ofFig. 3"to larger scale; method, and‘ relates more pat-icularlyto a novel construction for such shoes, and to a method of making such shoes. In making shoes or the open-toe pr open-heel Fig. '7' is a section, substantially on the line l--'l'oi Fig. 10'; ' Fig. dis a fragmentary perspective'view-of ‘the variety it is necessary to provide a ?nish for the 120. heel'endi of‘ the shoe showing the margin of. the edge of the middle sole where such edge is ex sock lining wrapped about. the~ edge of the mid posediat the toe or heel opening, or both.

For optimum appearance the edge ?nish shouldbe substantially identical in color, and 133K‘! ture with the exposed upper surface of the shoe bottom structure (usually a sock lining), butit ?ed, construction; is not always easy or expedient to provide a through theshoe of, Fig. 12, showing a heel arranged in. readiness for attachment; and Fig. 12, is a perspective View of a‘ lasted’ shoe having. a sock- lining like that of Fig. 11; ‘Fig. 13 is airagmentary longitudihalsection binding tape orribbon which matches the sock lining. Moreover, theapplication of this ribbon requires skill and is, slow,etime—consuming, and expensive.

Thepresent invention‘ has, for one of;itsaob. jectsthe provision of an improved shoe; of the open-end; type in which the edge ‘of; they middle sole, at. the. open end of the shoe, is ?nished 35 tomarily employedinthe manufacture of force lasted shoes. forward integral extension 2 at. its too end, this extension here being shown as of substantially fan-shape. having the forwardly divergent edges smoothly and so as to have identically the same texture and color as the exposed upper surface of. the. sock lining. Afurther object is tohpro vide a novel method-of making shoes of the-open. endvariety wherein the exposed end edge of the 40 middle sole. maybe ?nished acceptably, expedis tiously and at‘ a cost less than that involved in the, prior process, and which results in a shoe of improved construction and appearance, A further, object isto provide anjmproved sock lining. as a step product in the practice of the improved method of the, present invention. other, andfurther objects and advantages ofthe invention .will be pointed out in, the ‘following more detailed description, and by. reference; to the. accompanying drawings, wherein Fig;.»_-1 is-a plan view of an improved sock lin ing made in accordance with the present-inven tion; Fig. 2 is a bottomhview, to smaller sca1e,‘of a shoaupper havingthe improved sock, lining as! sembled' therewith; Fig. 3 is a view similar to Fig.‘ 2, but showing a middlesole'assembledmth the upper and sock lining;v , Fig. 4 is a view similar to Fig. 3 but showing Thisv sock lining, in accordance with the present invention,.is provided witha 3 and 4 and the. curved front edge 5. As illus~ tratedin Fig. 1, the. sock. lining l- is also fur nished with an integral. rear extension 6. extend ing. completely aroundthe heelend of the sock lining and terminating at ‘I substantiallyv in the line of .the heel breast. As here’ illustrated, the shoe upper comprises a .vamp- 3 having a lining 8a, the vamp being shaped to provide anopening? at the toe of the shoe. As here. shown, the quarter portion ll) of the upper is integral with the'vamp» 8, although it-may be. aseparate part if‘ desired, and this quarter is‘ cut: away to leave an opening it at theheel end of the shoe, the quarter at this-point beingmerelya strap I2 designed to embrace the ankle.’ As here illustrated, the outer member of the upper has a, lower marginal integral extension 81?. desi'gnedto constitute a wrapper. While here shown asintegrahit is to be understood that the wrapper. may be. a separate element, for example a stripof textile fabric stitched to the outer member of the upper. As illustrated, this wrap per member 8? extendsirom the opening at the 60 toe of the shoe to the point M which is sub‘ 2,414,105 stantially at the junction of the heel and shank portions of the shoe. In assembling the parts the lining member 8a The upper and sock lining are assembled in ac cordance with the proceeding above described, the last is inserted, the middle sole applied, and of the upper is secured to the marginal portion the wrapper and toe extension are wiped-in and of the sock lining l by an inseam Me which exsecured in place. The outer sole is also applied, tends from the Open-toe end of the shoe to the but in preparation for the application of the point l4. If desired vthe inseam stitches may pass heel H, the heel member [Y of the sock lining through both the outer member of the upper is tucked in, as shown in Fig. 13, so as to expose and the lining 8a and through the Substance of the heel end of the middle sole.
