. LI *I This invention f relates to improvements in shoe construction and particularly to'V the con-- struction kof insoles'thatare provided with sewmgps.,

the i-.manufacture of i shoesr itl has -become common toir'nalre)lirisoles lhaving solepieces of thin leather to avoilsubstantial increase in the' l hence are too thin to be' channelled to vprovide sewingflips to which the uppers and Welts'are attached. The lip of the Yilexiblesole pieces of sornefsic'hns'lesfare of the type shown in the De Vito et aLHPatent No. 2,205,716 granted July 2, 1940 and are formed Vof thin flexible strips of leather cemented to the lower surface of the sole pieces and each to the other and constitute, in effect, vcontinuations of the lips formed by channelling the 'thicker shanls of the insoles in the manufacture of full weltshoes. v `--It` is 4anobject of the present invention to provide an improved insole for either full or half welt' shoesfthe flexible sole piece of which insole is provided with lip strips of 'thin flexiblelmatei`a1` attached tothe insole and one loff-.which forms,y in effect, a lbinding for the edge ofthe sole piece for preventing the edge from coming loose from the strips and curling up or forming wrinkles which may produce discomfort to the wearer as has sometimes occurred where as heretofore the lip strips have been attached 'to the lower side of the sole pieces only.

In the accompanying drawings which show structure illustrative of the invention,

Figure 1 is a perspective View of an insole for a full welt shoe, the insole shown having the lip strip incompletely formed;

Fig. 2 is an enlarged sectional view taken on line 2-2 of Fig. 1;

Fig. 3 shows the upper lip strip of Figs. 1 and 2 drawn around the edge of the insole into contact with a lip strip on the lower surface of the sole piece;

Fig. 4 is a transverse sectional view through a side portion of a shoe and insole after the upper and the welt have been attached to the lip shown in Fig. 3; v

Fig. 5 is a sectional view, similar to that shown in Fig. 4, after the lip has been trimmed and leveled, cushioning lmaterial inserted and the outsole attached.

Referring to Fig. l, an insole is shown pro- 2 claims. (ci. sel- 22) v vided with a -heel and shank'portionIll,` and.v

since rthe"pa`nticular insole illustrated isfor use* ina full Weltc'onstruction', `the shank! is`chan-v nelled to provide alip I I whichzat fits forward z end'is'joined, as lbyc'em'ent, tothe adjacent ends of the Vlipstrips of the sole piece I2.-after' the latter have beenI completely formed.' The fori ward end of the shank is 'skivedor beveled at the lcwerfsicl'e4 thereof? whilefto the upper side'is cemented the vrear end portion of a beveled end' of the sole piece I2 which is 'of thin flexible'maii terial, Vsuch 'as shoe upper material or thinner'. stock. AGenerally 'a piece of canvas' or Vlike' fabric: I3 iscementedto thelower surface of the sole piece. A representation 'of theV edge "of theL fabricI I3 has beeny omitted fromrFig. vvv1 ofV the` drawing'because of thesmall scale of 'itheilatter but' is shown inthe remaining figures;

\ To the n lower surface of the. sole? piece I2 ist attached a lip strip- I4 of relatively thin'mate rial such as kid, the strip being providedwithan outwardly turnedv flange Idd which, in the manufacture of the insole, is initially cemented tofthe sole piece along the outer edge thereof. f The body I4b of the strip extends generally outward or at rightangles'to the plane ofv the's'ole' piece. A second lip strip I5 of similar.- thin flexible ma: terialisemployed in formingv the'fcomposite lip butinsteadiof beingsecured to`r the lower" face? of the sole piece' I2; as has" heretofore been the' general practice,it isattached't the' oppositeor upper surface of the sole piece. This lip strip I5 as shown in Fig. 1 extends :along the edge of the sole piece similarly to the strip I3 and has a flange I5a, extending outwardly that preferably is stitched to the sole piece by a line of stitches I6. Cement may be used also in securing the flange Ilia, to the insole. The stitches, as shown in Fig. 1 extend through the ange |411, also and thus securely attach the strips to the sole piece along the edge thereof.

For the purpose of providing a smooth joint at the junction of the sole piece and the upper portion of the lip strip I4 when the formation of the lip has been completed, a groove or rabbet II preferably is formed in the margin of the upper surface of the sole piece I2, of the width of the flange I 5a and in which the flange is seated. The depth of the groove preferably is such as to accommodate the double thickness of the strip I5 after the latter has been folded over the edge of the sole piece and attened down or leveled. In Fig. 3 the strip I5 is shown in the relation just mentioned, that is, it has been turned outwardly and downwardly over the edge of the sole piece I2, thence inwardly over the flange Ida and brought into face to face contact with the body Mb of strip I4 to which it is cemented. The rear ends of the two strips are likewise cemented to opposite sides of the respective channel lips I I formed in the shank to provide a continuous `-`securing lip extending along opposedsides of theshankand along the edge ofthe sole piece. Where an improved insole is` to be made for a half welt shoe, the lip II of the shank is omitted and the sole piece only is provided with a sewing lip, made as above described.

The composite lip shown in Fig. 3 formed b the bodies of the two strips I4` and I5 and designated generally by numeral I8 is rmly secured to the edge of the insole piece I2, the edge of the latter being enclosed by the strip I5y as shown. Hence in the completed shoe the edge of the sole piece is held down rmly by the composite strip, particularly by the strip I5 which is attached'to theupper surface of the sole piece and which, by reason of the construction shown, when'iiattened or leveled lies in the plane of the uppersurface of the sole piece. I l

In use of an insole, made in accordance with the foregoing description, it is first tacked to a last. An upper I9 isY then secured, as by staples or the like temporary fastening means (not shown) to the composite lip I6 ofthe insole. A welt 2D, beveled at the inner upper edge as shown in Fig. 4 and provided with a securing groove 2| is then, by stitches 21 secured in place, the stitches passing through the composite lip I8 and the overlapping portion of the upper I9; After trimming the edges ofthe lip and upper close to the line ofstitches 2l, leveling the same and inserting suitable cushioning `material 23, such as cork, felt orv the like, an outsole 2liA is securedrto the'weltV by stitches25. The shoe is subsequently completed by conventional or wellknown manufacturing steps'.

The improved insole, asn stated above, has its edgesrmly bound, by thelip strip construction described and is retained by the binding against loosening or wrinkling at the edge and thus upward curling that produceA ridges which impair the comfortrof the shoe.

While I have shown the improvements in the presentlypreferred form, various changes may be made therein within the spirit of the invention defined by the following claims.

I claim:

1. A flexible sole piece for an insole provided with a lip strip having a flange contacting the lower surface of the sole piece along the margin thereof and provided with a downwardly extending body spaced inwardly from the edge of the sole piece, and a second lip strip provided with a flange disposed on the upper side of the solev piece along the edge thereof,' said'v flanges being secured to the sole piece by a line of stitches common to the flanges, said second lip strip having a body portion extending from the inner edge of the respective iiange and extending outwardly -overthe latter and downwardly over the edge of the sole piece and inwardly and again downwardly into parallelism and contact with the body of the other strip to provide a sewing lip of double thickness.

2. Aiiexible sole piece for a shoe insole provided with a lip strip on the lower surface thereof, said strip comprising a flange secured to said surface and a downwardly projecting body portion, the marginal portion of the upper surface of the sole piece being provided with a ra-bbet REFERENCES CITED The following references are of record in the file of this patent:
