A pocket 23 is provided in the last in substantial axial alignment with the holes sole, whereby this construction makes it possible to set the jack-post in proper position to bring the bore through the heel into axial registration with the opening of the clamping bar 29 for final securement of the heel to the shoe. Also mounted in the dovetail track 6 is a carrier securable in adjusted position as by the 'set screw 4|, said carrier having an upwardly extending bracket arm 42 preferably slotted to adjustably receive the bolt 43 by which a com panion bracket arm 44, carrying a 'toe rest at its upper extremity, may be adjusted as to height above the base plate, said toe rest being preferably curved or of U shape to receive therein and steady the toe portion of the shoe during the heel securing operation. The adjustability of this toe rest is provided because of the different styles of shoes handled by this mechanism.

In Figs. 5 and 6 are shown one form of modified heel clamping bar, wherein the bar has trunnion ends such as 5| rotatable or rockable in bores provided in the upper ends of the slidable rods 21 and 28, the ultimate position of the bar 50 being 'adjustably secured by set screws such as 52. The central portion of this bar is provided with a groove or cut-away surface portion 53 for engagement with the surface of the heel, but the surface of this groove may be formed parallel to a face of the bar since the latter may be rocked or turned, through its trunnion engagement with the rods 21 and 28, to bring said surface into the plane of the heel, Fig. -6 showing in dotted lines an adjusted position of said bar. Obviously other modifications of the adjustability of this cross bar may be had including the omission of the set screws 52 but providing the surface of the ends 5| of said bar with longitudinally extending ridges or teeth adapted to engage correspondingly formed ridges or teeth on the inner surface of the upper ends of the rods 2! and 28, this construction permitting adjustability in predetermined positions whereas the set screws '52 and smooth surfaces of the trunnion bearings shown in Fig. 5 permit any adjustability desired.

The method of securing the heel to the shoe is as follows. Upon the last I is laid the necessary sole layers such as l5 and I6 with the openings therein in registry with the pocket 23 of the last, and the short screw 22 with its associated counter-sunk washer disc interposed between the layer l5 and the bottom of the last, said short screw dropping by gravity into said pocket, it

being understood that the last will be -in inverted position as shown in Fig. 2. The last with the sole layers may then be subjected to the operations of the lasting machine, sole laying, levelling, and subsequently to the welt machine, and trimming machine during the further buildingup of the shoe structure, Without interference from the short screw because the latter by virtue-of the pocket 23 is permitted to 'occupy such a position as to prevent it from extending upwardly into the way of the machine parts.

The shoe, still on the last I, is then taken :to the heeling room where the heel is applied 'to the shoe. The heel naturally has been provided with the bore [8 and just previously to placing the heel on the shoe the usual coat of glue is applied to the surface of the sole and to the heel seat, the glue being permittedto enter the enlarged portion of the bore adjacent the heel seat. The connector 2| is then screwed onto the end of the short screw 22 until'the latter has been worked upwardly out of the pocket 23 with the head of the screw contacting the counter-sunk portion of the disc washer. The outer surface of the connector is roughened, as by grooves shown in Fig. 2, so that when it ultimately is passed into the enlarged end of the 5 bore I8, the glue therein will enter said grooves and, upon drying, tend to key and anchor said connector in final position.

The heel is then applied to the shoe with the connector entering the portion of the bore pro- 10 then operates the lever or foot pedal to move 15 the heel clamping bar 29 downwardly upon the heel and, while the pressure of said clamping bar is still upon'the heel, a screw driver or other suitable tool is passed through the opening 30 of the bar and operated to thread the long screw 20 into the connector 2| to permanently secure the heel to the shoe, the head of the long screw ultimately coming into seated position on the metallic washer [9. The pressure of the clamping bar may then be released and, after the glued 25 joint has hardened, the usual top lift not shown may be applied to the bottom of the heel to cover the head of the screw 20.

From the foregoing description it Will thus be seen that by this invention there is provided a means for, as well as a method of, securing a heel to a shoe. The screws 26 and 22 together with the connector 2| constitute tensioning members for fastening the heel to the sole. The jack-post 4 together with the last I and the clamping bar '29 constitutes a means for applying pressure to the heel while it is positioned upon the sole; thus making it possible to lock the members 20, 2| and 23 under tension while the pressure is applied. Lastly by providing the pocket 23 in the last it is possible to apply the short screw 22 to the sole portion of the shoe and to perform the necessary operations upon the sole portion without interference from said screw.

It is obvious that those skilled in the art may'i5 vary the details of construction and arrangements of parts constituting the apparatus, as well as vary the steps and combinations of steps constituting the method, without departing from the spirit of this invention, and therefore it istso not desired to be limited to the foregoing disclosure except as may be demanded by the claims.

What is claimed is: 1. The method of securing a heel to the sole of a shoewhich consists in positioning the heel on the sole; applying pressure to the combined heel and'sole; and securing the heel and sole while the pressure is so applied, by independent tension applied'through the base of the heel.

2. The method of securing a heel to the sole of '60 ashoe by a plurality of tensioning members which consists in applying one of the members to the sole .portion of the shoe in such manner as to permit ready operations upon the sole portion'during the building-up of the shoe and applyinga second member to the first member after the shoe is built up; applying a third member to the heel and second member and positioning the heel on the sole; applying pressure to-the combined heel and v sole; and securing all of the members while the pressure is so applied, by independent tension applied through the base of the heel.
