SHQE AND THE MANUFACTURE THEREOF Filed Nov. 23, 1929 Patented Sept. 9, 1930 UNITED i STATES PATENT OFFICE FRED N. LA CHAPELLE, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO'UNIT ED SHOE MACHINEBY OOBPOBATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW ERSEY SHOE AND THE'MANUFAGTURE THEREOF Application filed November 23, 1929. Serial No. 409,392.

This invention relates to improvements in the manufacture of shoes and particularly to improvements in the insertion of fastenings adapted but not necessarily limited to use in 5 the manufacture of shoes. 7

Fibre or paper pegs, as disclosed in Letters Patent of the United States No. 1,729,169, granted September 24, 1929, on an application filed in the name of the present inventor, are beingused to a large extent in the manufacture of shoes. These fastenings hold with remarkable tenacity when driven into leather or other suitable material of any substantial thickness. When driven into the very thin material such as that used for the insoles of flexible McKay shoes, particularly those of the cheaper grades, however, they cannot always be relied-upon to hold, particularly if there is some variation in the thickness of the layers of stock which are being attached to theithin piece so that some of the fastenings, all of which in this work are ordinarily of the same length, do not pass entirely through the thin layer.

It is an object of the present invention to provide, an improved method of inserting pegs, applicable though not limited to the securing of the overlasted marginal portions of'shoe uppers to light and thin insoles, which will insure firm anchoring of the pegs even though the substance of the insole stock may be so thin and flimsy that heretoforeclenched metallic fastenings would have been necessary. In accordance with the method of the 5 present invention as herein exemplified I ob tain this result by securing a sheet of stifi material, such as fibrevboard, to the material of the insole at the side thereof adjacent to the shoe upper and, by forming a fastening receiving hole in the layers of the material, forma burr from the fibre board or other stiff'material which, when a paper or fibre peg is driven into the material, firmly grips the peg and prevents it from being pulled out.

In another ofits aspects the invention comprises an improved shoe or other article layers of which are secured together by a paper or fibre peg or pegs passing through a sheet of stiff fibre board or analogous material secured 0 to one of the layers and between that layer and another layer, the pegs being held against withdrawal by burrs formed from the fibre board.

With the above and other objects in view the invention will now be described in connection with the drawings which illustrate the. forward portion of a shoe the upper of which is secured in lasted relation to the insole by fastenings inserted in accordance with my invention, and will be pointed out in the claims. r

In the drawings,

Fig. 1 is a perspective view of the forepart of the shoe positioned bottom upwardly, the upper being secured in lasted relation to the insole, at the toe portion of the shoe by fastenings inserted in accordance with this invention;

Fig. 2 is a perspective view of the forward and shank portions of an insole having a thin sheet of fibre board secured to its toe portion in order to anchor fastenings thereto;

Fig. 3 is a longitudinal sectional view on an enlarged scale through a portion of a shoe lasted as in Fig. 1, during the performance of the lasting operation, and showing the awl of a fastening inserting implement at a time when ithas passed through the layers and substantially contacts with the metal bottom plate of the last; and

Fig. 4 is a longitudinal sectional view through the toe of the shoe of Fig. l, on the same scale as Fig. 8, showing a fastening which has just been inserted by the driver of a fastening inserting implement.

The invention is illustrated and described herein with reference to the lasting of a McKay shoe 10 the marginal portion 14 of the upper 16 of which is secured in lasted relation to an insole 18, from substantially the tip line rearwardly to the heel breast line by staples 20 which are deflected as they enter the stock so that they are anchored in the insole, as disclosed, for example, in an application for Letters Patent of the United States Serial No. 209,299, filed July 29, 1927 in the name of George Goddu.

The toe end of the shoe upper, and the heel portion also if desired, is secured in lasted relation to the insole 18 by paper or fibre pegs vided with a nozzle 24 (Figs. 3 and 4) and-a tool 26 g which actsbothas an awl and asa driver.

In order to'in'sur'e that the pegs 22 will" hold in the insole 18, even though the latter,

be of thin and relatively fiimsymaterialsuch as a cheap leather split of two-irons or thereabouts (one iron equals 1/48th of an inch) in thickness, asheet of hard istifi material such as fibre board 28 is secured,for example by a suitable adhesive, to the insole 18. The

insole "is mounted ona last 30 (FigsBand f fills the hole, formed by inadequate, by reason of its 4) having the usual bottom plate 32 with which last of the type used inmaking McKay shoes are provided. Afterthe side lasting hasbeen performedin the manner men tioned aboveor in any other suitable way the material is Worked into lasted position at the ends of the shoe, for example by-a bed lasting machine, and is secured to the-insole l8-by the pegs 22. When the nozzle 24: of the fasteninginserting implement is, pressed against aportion of the shoe upper which has been worked into lasted relation to the insole and the implement is operated to insert a fastening, the tool 26, acting as an awl,-is

forced downwardly, passing-{through the layers of the shoe upper, as'i'll-ustrated the upperleather 34, the doubler 36,-box-toe 38' and the lining 40. The tool 26 then passes through the fibre board 28 .and the insole 18, burring the fibre boardas shown'at42inFig. 3. Then thetool 26 is withdrawn and, after the peg 22 l1as been-brought into the nozzle 24, the tool 26 is operated, actin g as a driver to insertthepeg 22, as she n in Fig. 4. It will be observed that the peg 22 completely the tool 26 in the layers of stock and that any'tendency to withdraw the peg-tends to return the burred portion 42 of the fibre board 28 toward its original position thusgripping thepeg even more firmly and effectively preventing its withdrawal under any ordinary stresses. As the sheet 28 of the'fibre board is secured firmly to the insole 18 a firm anchorage for the pegs is obtained even though the insole 18 may be thickness or consistency, if it alone were relied upon to hold thepegs. V If desired, and as illustrated in Fig. pegs may be somewhat longer than the thickness of the layers into which theyare inserted so that they will be headed at their upper ends. This will effectively prevent the layers of the stock from pulling ofi over the head ends of thepegs.

While the invention has been-illustrated 4, the n Obviously it may be used for other purposes 7 not necessarily relating to the manufacture of shoes. 1 i
