This invention relates to shoes and methods of manufacturing the same, and has special reference to improvements in the so-called slip-lasted type of shoe. This type, as is well understood, is

chiefly distinguished by the manner in which the is to construct a shoe in general accordance with the prescribed slip-lasting method but with certain improvements therein that enhance "the comfort, appearance, and wearing quality of the shoe.

An important object of the present invention is to construct a shoe of this charactenwherein the inner sole members and stitching at the sole line are concealed. Although this, of itself, is not a new concept in slip-lasted constructions, all former methods have incidental disadvantages, not the least of which is the creation of wrinkles in the linings of the shoes. It is the purpose of this invention to provide an improved and more efficient construction that eliminates such objections.

Another objection to such former constructions "is'that the outer ply of the upper that serves to hide the sole line stitches requires special and w skilled manipulation to conform it to a last, akin to that required in connection with hand and machine lasted shoes. The objection is avoided in the presently described construction by producing an upper assembly which is completely fashioned prior to the introduction therein of the last, and whereby the outer ply conforms itself to the shape of the inserted last so that little or no effort, skill or experience is required by the shoemaker in the operation of turning in and securing the lasting allowance. Accordingly, the fundamental advantages of the slip-lasted process which heretofore were only partly attained in hidden stitching constructions are fully realized by the improved method of the present invention.

These and other objects and advantages will be more fully explained in the description that follows, reference being made to the accompany- 7 Claims. (01. 36 -195) assembly. for an open toe, open heel type of womens shoe;

Fig. 9 is a plan view of a sock liner of modified form, and

opening as indicated by the lines of stitching l2,

and along edges which define openings in the upper, such as by stitching l3 and I4 at the margins of the heel and toe openings. As appears in Figs. '2 the lining ply is provided with trace marks It to indicate lineswhere the said lining ply, later in the process, is to be stitched to the sock liner Hi. The lining ply H extends beyond the trace marks to provide a substantial marginal allowance, this bordering strip being desirably made one-quarter of an inch or greater in width for purposes which will hereinafter appear. In this respect the present construction differs from the customary construction, wherein the upper linings terminate approximately at the sock lining or sole level. The outer ply I 0 also is extended to provide a bordering strip for lasting purposes, and such bordering strip preferably projects a short distance beyond the lower extremity of the lining ply, as shown. v I p The sock liner I6, of textile fabric, or thin pliain. the. so1e--.structure correspond g to: ha

posed by reason of openings 'inthe upper, asset.

the heel and toe in the present example.

The sock liner is attachedtosthe lininglply:lli of the upper by stitches 2i which izollow -tlle 'tracie; marks [5 on the lining ply. *Ihe "stitches 2! do not engage or pass through the outer ply l0. Thereafter the lining ply istsecllredrto the uter ply by means of cement applied between .andto the adjacent surfaces, or by a row of stitches-22" that extend along the lower edge of the lining ply, -or both by "cementingand stitching.

Allof the foregoing steps are lperiormedoif the-last and involve simplecutting, "stitching: and cementing operations. At this stage of the process (Fig. 6) the disposition ora'rrangement of the outer ply relative to the lining. ply and thesock lineris fixed sincerthe plies are .secured together both at their top and .bottom .margins. Accordingly it may be said that 'theuppen assembly is completelyvfashioned prior to the introduction therein of the last. The present method thus distinguishes from former methods wherein the lowermmargi'n of the outer ply. is left free until after-theJast-has been inserted; In such case the outer. ply is required to be 'molded to the last and: its marginal extension. secured to the sole structure independently oi the lining .p1y,'which requires careful and painstaking manipulation. by a highly. skilled shoemaker. .i

Continuing now. with .the: description of the method'ofthepresent invention, a last 23 is inserted in the pre-formed assembly-of F g. 6, and the bottom or. exposed-surface.oi-thegsock liner is given a coating of adhesive, adhesive being also, appliedato the. imier, surfaces of the marginal. extensions, of the upper and. to that of the heeLand toe-tabs i'l and l8; If theshoe is to be provided with an insole or platform such member, ndicated bylnumeral 24, is positionedon andvsecurecl vto the exposed: surface ofthe sock-liner.

It is in connection with the last recited operation of pulling, turning under and securing the marginal extensions of the plies to the sole structure that the value of the earlier operation of uniting the marginal extensions of outer and lining plies is particularly manifest, Thus, when drawing and turning under the marginal extensions suflicient tension is exerted thereon ts cause both plies to hug the surface of the last. Sincethe extensions are united, they may beg'manipulated as a unit in a simple manner and the tensioning force is imparted with like efie'ct tobo'th plies. This is conducive to the avoidance of -Wrinkles and distortion in the lining ply which otherwise results when the outer ply is manipulated individually as is the case in former,preposedgconstructions. Itwill be understood hat irregularities in the lining ply caused by-=-unequal tensioning are not observable until the last is removed, and then it is too late to efieettheincorrection. 1
