Application September 18,1944,-Seri'aINoFBB ILGM (Cl. .-12--T142 :21Claims.

. 21 i :This invention relates :to Ifs'h'ce manufacture *zandz'p'ertains more particularly to improvements Thetprincipal purpose :"of "the ainvention -is treesvorrother .device's to preserve the :flat set of the sole, ;;and which is v:unusually comfortable .to -the :wea-rer, especially in :the vamp :area.

--:One of :the primary features 0f the improved construction is the provision of a resilient, sheetdike :bottom .filler which iscsecured to the lasted insole w :under tension rand continuously resists any tendency. of .the shoesole'to bow upwardly. at the toe; :thusholding the :sole flat and :avoiding the. formation of :wrinkles in the insole :o-ri creases inthe -vamp..

.Another feature is :the incorporationin the vamp of a cushion-like, iresilient'i'lafyer or lining -.which not :only {affords ggeneral comfort to: the wearer by relieving excessive pressure I011 .zcorns :or bunions, rbutzalso resists :distortion ofsthevamp and, *when combined with :the'resilient bottom filler, .:tends to counteract zany excessiverstraiin of 1 the tensioned filler :and :thus :.assists in gameserving theinitialz'shape .of the :shoefsolei as' well as: the :forep'art iGf itsxupper.

Recommended .iembodiments of ithe invention are illustrated in the accompanying zdrawings, buti-itwi'llbe understood that the structural details of the shoe parts herein shown and described may be widely varied without departing from the essence of this invention as defined in the appended claims.

In the drawings,

Fig. 1 is a bottom view of a lasted shoe prepared for the application of a preferred form of resilient bottom filler sheet;

Fig. 2 is a plan View of the sheet filler adapted- Fig. 5 is a side view, partly in section, of a 7 the .improved 1=features rm'ay The incorporated ".I-in lother itypes .Df shoe, if lldesired.

The rsheetlike, resilient ibottom .filler H ltmay consist rof 5a suitablyzshapedipiece iof .Zperforated scrap rrubber nor" Lethecharacter. described in 'my Patent No. 5250533502, -.fdated September 8, 1936, and-when .such ;a rzfiller is iemployedx ititpossesses all the advantages explained sin .@that. patent aa's -well as the :novel .features :herein idisclos'e'd. 'Gther stretchable," resilient," or I contractile materials or .compositionswill, ihowever, isat'isfy r'the purposes. of th'expresen't invention, sollongras 'they mayrbe suitablyvfastenedvto Ithe insole under appreciable'atension an'd thereby icause the sole .of 1 that-finished shoe to maintain ziits' flat kcondi- 'Ition'nniderrnorma-l :use.

Thearesili'en't ishee't -is adaptedto'fill the forer zandwelt ll, tonithe-ilast l5. In accordancewith this invention longi tudinally spaced fastening @elements, such Ias the: snap sockets "t6 of it Figs. 1 "and 3, eare' alt'tache'd i tothe insole l 2 -be'fore it "is tacked son isthealas't. I he :shoe is then lastd, wltedpandmrepared tor -bottom inning.

The sheet filler l l is prepared to fit the bottom cavity and complemental fastening elements, such as the snap studs ll of Figs. 2 and 3, are secured thereto at longitudinally spaced intervals. The fasteners are provided at the toe and ball regions, and preferably also at the shank, as shown; but the third fastening will be omitted if the filler does not extend into the shank of the shoe.

The distance between any pair of fasteners on the resilient filler is substantially less than the distance between any complemental pair of fasteners on the insole. The difierential may be approximately five-eighths of an inch in each case, as in the arrangement shown in. Figs. 1 and 2.

Hence, in applying and securing the filler, the resilient sheet must be stretched longitudinally to attach the complemental snap fasteners, and is then held in place under appreciable tension. Suitable cement is preferably applied between the meeting faces of the insole and filler to bind them together; and after the cement has dried, the outsole I 8 is applied and secured according to common practice.

' sole. The rivet head may, of course, be counteru f si cd-n h v In Figs,"' 3 {and 5', the vampof theshoe is equipped'with'the improved cushion'layer 2| inserted as an interlining between the upper l3 and the usual fabric lining 22 and secured therewith to the insole by the ordinary inseam stitch of a welt shoe. As shown in Fig. 6, this cushion layer preferably consists of a thin sheet of sponge rubher or other soft and resilient material, having small perforations 23 therethrough to permit adequate circulation of air. The pores and 'perforations of the layer 2| also tend to obviate damageto the upper resulting from perspiration, for perspiration will collect therein and be evaporated without wetting the upper proper [3.

Other suitably porous or permeable sheets may be satisfactorily employed as the cushion lining or layer, such as foam rubber, or wool felt; and a rubber layer 24 may be spread coated or vulcanized on the outer side of the textile fabric lining 22, if desired, as indicated in the modified form of Fig. 7. When applied as a separate sheet,

thecushion layer is preferably stretched outwardly from the center and cemented or'otherwise attached to the upper 22 under tension, be-

7 fore the upper parts are assembled, and thereafter cemented to the lining l3 to unify the vamp at or prior to lasting of the shoe.

The yielding resilience of the cushion layer 2| or lining tends to relieve pressure on the foot and also, because itis connected through the insole to the resilient bottom filler, to assist the stretched filler II in maintaining the shape of the sole and upper at the forepart of the shoe, and to resist excessive tension of the stretched filler. The combined effect of the stretched filler sheet ll of the sole and the stretched layer 2| of the vamp results in a balance of tension which maintains the sole in' flat position and preserves the fitting qualities of the vamp, when the shoe is off the foot, yet permits flexing of the sole and maintains the upper parts in unwrinkled condition 4 when the shoeis worn. The usual leather upper and fabric lining are inherently stretchable, under the flexing caused by walking and will conform to the condition of the resilient cushion layer 2|,

so that said layer obviates wrinkling of the lining or the upper under all conditions.

A shoe constructed as herein described is extremely comfortable to wear and maintains its unwrinkled and uncreased shape indefinitely.

The springinessof the sole which is constantly urged toward a flattened condition, under the counteracting effect of the vamp lining, by the ness of the sole is apparent when the foot is relaxed as well, as when the shoe is removed from the foot.

I claim:

1. A method of making shoes comprising the steps of preparing an insole having fastening elements spaced longitudinally on its bottom surface, lasting an upper to the insole, preparinga sheet-like, stretchable and resilient bottom filler having complemental fastening elements spaced longitudinally thereof with the distance between each pair of complemental fastenings'substan- .tially shorter than the distance between the corresponding pair of fasteners on the insole,

stretching the filler and fastening it to the'intension, and then applying an 'outmental fastenings substantially shorter than the distance between the corresponding pair of fasteners on the insole, stretching the filler and fastening it to the insole under tension, and then applying an outsole. r
