METHOD FOR USE. IN LAST'ING SHOES Filed April 50, 1947 5 Sheets-Sheet 2 Dec. 7, 1948. P. E. BURBY 2,455,467

METHOD FOR USE IN LASTING SHOES Filed April 50, 1947 s Sheets-Sheet s Invenfor I Philip E.Burby I By his Attorney I fasten an end of a binder wire to a tack at one side of the shoe bottom and to apply the wire preliminarily against the upper around the toe adjacent to the wiping faces of the wipers. After the machine is again started the wipers are lifted slightly and are partially retracted lengthwise of the shoe and opened to enable the operator to pull the wire inwardly against the upstanding margin of the upper lying against the lip of the insole, after which they are again fully advanced and closed to press the wire against the upper and are moved downwardly to increase their pressure on the upper. The machine then comes again to a stop to permit the operator to fasten the wire to a tack at the other side of the shoe bottom and to sever the binder from the rest of the wire. In practicing the method of the present invention the operator uses, instead of wire, a strand b of elastic binder material, which may be rubber or other suitable material, as hereinbefore explained, and may be obtained from a reel; This strand of material will be of such thickness that when stretched it will hold the upper as required in the angle between the feather and the lip of the insole without interfering with the attachment of the welt to the shoe in the usual manner. The operator fastens an end portion of the elastic binder material to the shoe at one side of the shoe bottom in a manner hereinafter explained after the machine has come to a stop the first time, and after it has again been started he pulls the strand of material inwardly under the wipers and against the upstanding margin of the upper while stretching it lengthwise of the edge of the shoe bottom. When the machine has again come to a stop with the wipers in pressing and holding relation to the upper and the binder material, the operator fas-. tens the latter at the other side of the shoe bottom and severs the portion applied to the shoe from the rest of the material.

Further in accordance with the present invention the binder material is fastened to the shoe at the opposite sides of the shoe bottom by forcing portions of it in a stretched condition through the margin of the upper and the lip of the insole in the form of loops and then releasing the loops to permit them to contract at the inner side of the lip, the increased thickness of the looped material by reason of such contraction anchoring the binder efiectively in place in its stretched condition. For thus fastening the binder material when the toe is lasted by the use, for example, of a lasting machine such as shown in the previously mentioned Letters Patent, there may be conveniently utilized the hand tool shown in Fig. 1. This tool includes a casing having integral therewith a handle l2 to assist the operator in positioning it first in a relation to the shoe such as illustrated in Fig. 1. Mounted to slide along guideways in the casing is a bar 14 an end portion of which is arranged to extend downwardly when the tool is positioned as in Fig. 1 and is provided at its lower end with projections l6 spaced from each other and arranged to engage the bottom face of the insole to determine the position of the tool heightwise of the shoe and in the operation of the tool also to engage the inner face of the lip a of the insole. Formed on the bar l4 are rack teeth 18 engaged by a pinion 20 rotatably mounted on a pin 22 in the casing l0, and also engaged by this pinion on its opposite side from the bar [4 are rack teeth 24 formed on an upraised central portion 26 of a slide 28 movable along guideway in the casing in parallel relation to the bar l4. Ex-

tending into the slide 28 from its left-hand end (Fig. 2) as far as its upraised portion is a recess 30. Supported on the top of the slide 28 is a shorter slide 32 having a recess 34 therein to clear the upraised portion of the slide 28. Extending downwardly from the left-hand end of the slide 32 into slots 36 in the sides of the slide 28 are two lugs 38 to limit relative movement of the two slides. Mounted in a socket in the slide 32 and engaged by the right-hand end of the upraised portion of the slide 28 is a compression spring 40. The purpose of the slide 32 is to clamp a portion of the binder material b against two spaced upwardly extending fingers 42 fast on the upper end of a rod 44 movably mounted in the casing I0. Such clamping action takes place upon movement of the slide 32 toward the right through the spring 40 by movement of the slide 28 in that direction. For imparting that movement to the slide 28 a handle 46 is pivotally mounted on a pin 48 in the casing 10 and has integral therewith a forked arm 50 extending upwardly into the recess in the slide 28 and provided with a pin 52 rotatably mounted therein. Extending through a hole in this pin is a rod 54 pivotally connected to lugs 56 on the slide 28. Mounted on the rod 54 between a shoulder on the rod and :a washer 58 engaging the pin 52 is a compression spring 60. It will thus be seen that upon movement of the handle 48 toward the handle l2 by one of the operator's hands in engagement with both handles the slide 28 is operated as described through the spring 60 and acts through the spring to move the slide 32 into clamping relation to the fingers 42. At the same time the pinion 20 acts on the bar M to press the projections 16 on the bar yieldingly against the inner face of the lip a on the insole. The arm also serves, by the same movement, to operate a needle 62 which engages the portion of the binder material bridging the space between the fingers 42 and forces the material in the form of a loop through the upstanding margin of the upper and thelip of the insole. The needle is secured at its outer end to a block 64 provided with a pin 66 which extends into slots 68 in the forks of the arm 50, and it extends through openings in the slides 28 and 32 With some clearance between it and the slide 28. The needle has a beveled end positioned initially as shown in Figs. 1 and 2 to support the binder material placed upon it between the slide 32 and the fingers 42, and after the material has been clamped by the slide against the fingers further movement of the needle causes its beveled end to deflect upwardly the portion of the material engaged thereby,

which is prevented at that time by the fingers from moving with the needle. This portion of the elasticmaterial, upon further movement of the needle, snaps downwardly into a recess 10 extending transversely of the needle, as illustrated diagrammatically in Fig. 5. The needle thereafter carries the material along with it in the form of a loop through the margin of the upper and the lip of the insole, at the same time stretching it by reason of the fact that portions thereof at the sides of the needle are clamped between the slide 32 and the fingers 42. In this operation the material may slip to some extent between the slide and the fingers in response to the pull of the needle thereon. The needle thus passes inwardly between the two projections [6 of the bar 14 which support the lip at its inner side against the thrusts of the needle and are pressed yieldingly outward against thelip through the action of the spring on the pinion 20.

After having thus fastened the binder material at one side of the shoe bottom, the operator preferably det'aelres the meteriei extending around the toe from the recess betweeh the wipers and the upper and then epplies a pun to the material at the ri'ght hand side 'of the sho'e to stretch it and to draw it more tightly into the recess adjacent to the wipers. While holding the materielunder tension the operator thereafter starts the machine to cause the-wipers partially to retract and to relax their downward pressure on the upper and the'rebyto permit the binder material't'o be drawn inwardly under the wipers against the upstanding margin 'of the upper. 'As hereinbefore explained, the wipers arcathen again fully advanced and "closed" and are forced "downwardly eigainst the upper to hold it lasted-position and also to hold the binder material in its stretched condition age/instthe upper, After the-machine has again:eerneto a stop with the wipers inthese positions, the operator proceeds to fasten the binder material at the right-hand side of the shoe bottom in the same manner as previously at theleft-hand side, as illustrated in Fig. 9. In thus operating at the right-hand sidethe operator, in positioning the material on the beveled end of the needle between the fingers 42 and the slide 32, applies a pull thereto to stretch to some extent the portion of the material extending from the adjacent wiper 2 to the fingers 42. Accordingly, when the fingers are moved downwardly to release the clamped material near the end of the operative movement of the needle, the contraction of the portion of. the material extending beyond the wiper 2 will cause it to snap in against the upper, so that no objectionable loosening of the binder will take place when the wipers are withdrawn from the shoe. After thus fastening the binder material at the right-hand side of the shoe the operator severs the portion applied to the shoe from the rest of the material, cutting the material at such a point as to leave only a very short end thereof projecting from the margin of the upper. Preferably also he similarly trims the projecting end portion of the material at the lefthand side of the shoe.

It will be understood that the elastic binder applied and fastened to the shoe in the manner described serves effectively in its stretched condition to hold the upstanding margin of the upper with a constant force against the lip of the insole, any loosening of the binder being prevented by reason of the increase in thickness of the material forming the loops at the inner side of the lip after the loops have been forced inwardly in a stretched condition and released. It will further be evident that theelastic binder will not be in the way of the welt when the latter is applied to the shoe and will not interfere with the needle of the welt-sewing machine. The nature of the binder applied and fastened as described is, moreover, such that it need not be removed from the shoe, although obviously it may be removed if desired.

Novel features of the binder-fastening tool herein shown and described are claimed in a divisional application Serial No. 21,368, filed on April 16, 1948.
