Shoes embodying insoles and outsoles made in 3 accordance with the teachings of the above men- `tioned Sbicca patent; wherein an insole is sepa- `rated `or split froml a piece of outsole stock while leaving la raised landed portion at the central forepart area of the outsole andfforming a com- 3 plementary aperture inthe corresponding portion ofwthe insole, have become increasingly popular,"
f such supporting means includes an element which is particularly useful in following the steps of the Other objects ofthe invention'will in part be obvious and will in.` part appear hereinafter.
3 "AIheinvention accordingly comprises the sevl 3 eral steps and the relation .of oneor more of such steps with respect to each of the othersfandthe article possessing3 the features, properties, `and the'relation of. elements, which areexemplied in the following detailed disclosure; and the scope ofthe inventionwill be indicated in the claims.
For a fuller understanding of the'nature and objects of the invention, reference should be had to the' following detailed description taken.3 in
connection with the accompanying drawing,3 in which i '3 Fig. 1is 3a perspective view of a complementary insole `ariel outsolefblank` showing the insole par- 3tiallysplit orremovedtherefrom;` f 3 33 s Fig 2 isa perspective view of an insoleand V associatedpartsconstructedand provided in accordancewith i the principlesof the-3 present invention;v 33 A i Fig. 3 is ajfragmentary transverse sectional view, on an enlarged scale, showing the insole3 of l Fig. 2 locatedjona'at bottom last;
Fig. 4 is afragrnentary transverse vertical seci' tional view,` corresponding to Fig. 3 and showing an upper lastedto theuinsole; 3s
Fig; 5 is a fragmentary transverse vertical sectionalwiew correspondingtoFigs. 3 and 34 and Fig. 6 is `a transverse vertical sectional view across the forepartWofia completed shoe constructed in accordance with the principles 0I the and` there are now many manufacturers who wish to make them. For3 reasons that are'famil-3 3 lar tolthe art, and are more fully described in the n n s 3 above mentioned Maiellano application, this type s d prises 3a 3shield which is capable of protecting the 3 `insole asglainstfundesired tearing' and abrading3 of `shoe is more readily adapted to be made on elevate the marginahportions of the latter with respectto itscentral forepart portion during the sole aixingoperation, sothatwhen ilatl bottom of an `outsole to the' round bottom lasts than onthose having at bottomslyin viewof3 the `fact that the" introductionl i of lasting3 allowance material between the com- 3 plementary insole and 4outsole :tends relativelyto y l 19, 1934 or in any other suitable manner capable matedginsole andjcnrtsole` lasts are used, it is preferable to provide means to support this portion of the outsole to assist in preventing an undesired depression or recess at this part of the shoe. However, many manufacturers have flat bottom lasts in'stock, and while they prefer to make shoes having the Sbicca type construction, they naturally wish to avoid, if possible, discarding their existing flat bottom equip ment and may wish to avoid additional skiving, coping, or roughing operations on the leather to afford room for the upper lasting allowance. The present invention provides a shoe construction which renders this possible.
Referring more particularly to the drawing, there is shown in Fig. l arounded blank I of outsole leather which is adapted to have an insole II splitr or removed'from the'flesh side thereof. The removal of'such insole leaves an outsole I2, and the removal is so effected that a raised land il is left at the central forepart portion ofthe outsole and arcorresponding aperture Il is `providedjin the insole which is shaped and contoured soasexactly lto tilt and complement the land on the outsole; Buch complemen- /tary insole and outsole maybe made by the three cut process injthe'Sbicca-Patent l No. 1,902,725 orfitV maybe'fperformed in a single of giving the required construction.
`4`operation on the the-manner disclosedinqthecopendig'tappli'cation of William C. Card. dnerialfNo. 748,979, October The outer marginal :edge
size f somewhat less .than that of the outsole. This'trimmingmay be effected bythe preliminary removal of -a marginal rand before the insole is split from the outsole, as shown in Sbicca Patent No. v1,838,708; or by. a separate `rounding application following its removal; or in any other suitable manner.v
l The trimmed and apertured yinsole is next furnished with a ply'of sheet material Il, which kis shaped so as to overlie the margin of aperture Il for ka short distance, its outer edges being preferably located at or slightly inwardly from the inner boundary of the marginal lasting allowance area provided at the forepart oi' the insole.VV That is, the sheet is preferably dimensioned so as to lie within the inner edges of the overturned lasting allowance of an upper lasted latex, whichlmaybe applied entirely over one side thereof, so as to provide temporary adhesive contact between the outer margin of the sheet andv the inner `margin of the insole adjacent aperture il, while presenting an exposed tacky surface within such aperture. 'This sheet is stuck to the lasting side of the insole, which is the split or grain side when itis intended that such i insole side shallbe` reassembled in opposed relation with the split ordesh side of the outsole from kwhichit was removed., Sincev the split, surface of the insole is sometimessmoother than the flesh side, some manufacturers vprefer to reassemble theinsole split from a right outsole in il of the insole is trimmed .or rounded in any suitablemanner to a reversed position on a left outsole, so that the split surface of the insole will be exposed in the interior of the shoe. If this is done, the sheet i5 should be stuck to the flesh side, which will then be the lasting side. If desired, the stifi'ening sheet IG may be attached to the insole prior to the trimming operation at i5, assuming that the latter is performed after removal oi' the insole from the outsole,r in which caselit will serve to strengthen the insole during such operation.
A filler piece is next applied to the central forepart portion of the insole on the opposite side thereof from sheet i6. This filler piece is preferably of composite structure, comprising a ply il, which also preferably is formed of fiber board in order to impart added stiffness and strength to the insole, to which is permanently cemented i a ply il of felt or like material. 'I'he fiber board ply i8 may be somewhat larger than the sheet Il, and the felt ply Il, which is thicker than the fiber board, is preferably feathered along its outer margin, asl illustrated.- The thickness of the composite ller piece equals or approximates that ofthe upper materials which are to be lasted to the insole. Such filler piece is located across the aperture il, the ply, il thereof being stuck to the 1temporary adhesive `ii .which is exposed through such aperture.
An alternative and presently preferred proce- Adure forfassembling'the sheet membersv I6 4and the v filler piecefior'l member with the insole comprisesgcoating-the freenface of theriller piece `ply ild'witlrtemporary adhesive su'chas a suitable forxnloflatex and sticking the filler piece to the'inclined marginof the insolel'bounding the aperture i",v f 4".lhe protective sheet member i6 is then stuckoto the tacky' surface of the filler vmember throughVV such aperture.
l Thisv procedure has the'advantage of, preventing the undesireddeposit of latex or other foreign material on the lasting side of the insole adjacent its aperture margins, thus leaving a clean surface at such margin for the reception of permanent cement, such as pyroxylin, during the subsequent outsole aillxing operation.
The insole thus constructed is located on a last,'which mayrhave a fiat bottom, .as shown in Fig. 3.l vIn locating the insole, the felt filler piece ply is positioned against the bottom of the last, and the stifi'ening'" ply II `is outwardly exposed.
'I'he assembled upper 2li, is next pulled over the last and'its lasting allowance 2i is lasted thereto,
preferably' by means of pyroxylin cement or the like, although other types of lasting, such as stitching or stapling maysbeadopted, if desired. When cement side lasting is employed, the martom, and the presence Aof the iiber'board sheet I 6 prevents ythe roughing tool used for such operation from' tearing or abrading the thin inner Fig. 4, and this overturned lasting allowance may lalso be roughed to prepare it for cement attachment to an outsole. The sheet it also acts as a protectivev shield for theiin'sole' during this bottom roughing operation.
After the upper has been permanently lasted to the insole, the sheet Itis removed by tearing or pulling it away from the bottom of the lasted l ginal lasting allowance of the insole shouldbe yroughed prior to its .location on the Ylast vbotv.with said land, temporarily attaching a sheet of material to one side `of said insole across its aperture, roughing themarginal portion of said insole beyond said material,` positioning a filler kpiece on the 'opposite Aside of said insole and temporarily attaching it to said material through said aperture1ocating said insole on a at bottom last with said; filler piece facing the last bottom, cement lasting an upper tothe roughed margin of said insole, bottom roughing such lastedupper, removing said material from said yinsole and from said filler piece to expose. said insole aperture, cement aiiixing said outsole to said lasted upper with its land fitting said aperture, delasting theshoe thus formed, and removing said filler piece `from the interior thereof. l
