Patented Aug. 12, 1919;

Application filed February 15, 1916. Serial No. 783521.

To all whom it may concern:

Be it known that ORRELL AsHroN, deceased, late of Swampscott, in the county of- EsseX and State of Massachusetts, invented certain Improvements in Apparatus for Use in Assembling Soles on Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoes andmore particularly to means for securing greater accuracy and effecting economy in shoemaking. The soles of good turn shoes consist of high-grade leather of the most expensive quality. One object of this invention is to provide means to assist an operative in placing a sole on a last, preparatory to assembling the upper therewith, with its edge in proper symmetrical relation to the edge of the last so that the shoe can be correctly shaped over the sole. Another object is to insure the placing of the sole on the last so that a minimum of sole edge trimming shall have to be done and therefore a minimum of waste of valuable stock shall occur in finishing the shoe.

A feature of the invention consists in means constructed and arranged to engage the work at a plurality of points for positioning a sole symmetrically relatively to an end of a last. The illustrative embodiment of the invention comprises feelers with which the last and the sole may be brought into engagement at opposite sides of the end of the toe. and also at the end of the toe. These feelers comprise relatively adjustable niembers for engaging, respectively, the side face of the last and the edge of the sole to adapt the apparatus for turn shoe work, the sole edge member determining the extent of pro jection of the sole edge beyond the edge .of the last. With each feeler is also preferably associated a finger to engage with the top face of the sole to assist the operator in using theapparatus.

Another feature of the invention consists in the organization of the apparatus for ad justment of a plurality of: feelers together.

As shown, opposed side feelers, which are" arrangedfor engagementw iththe work at thecorners of the toe, and an intermediate,

teeler, which is located? to engage the end of the toe, are mounted on relatively movable supports which are connected for movement of two feelers together for adaptation to the size of the work. A spring is arranged to hold the feelers in anormal position from which they may be spreadby engagement with the work; and, for alternative use, a binding screw isaarranged to secure the feelers in definite adjusted relation.

A further feature of the invention consists in the combination with sole locating means of means cooperating therewith to secure the sole in the correct location on the last.

The invention will be. more fully explained in connection with the accompanying drawings and will then be pointed out in the claims.

In the drawings,

Figure 1 is a side elevation showing this invention applied to an insole tackingmachine.

Fig. 2 is a perspective view of the new mechanism, and

Fig. is a sectional view illustrating a use of the invention.-

The illustrative apparatus comprises a standard 1 which may be supported by a bracket extending laterally from the post of a tacking machine such as that shown; in

United States Letters Patent No.- 1,106,393, granted Aug. 11, 1914,- on application of Fred L. Mackenzie. The head of the standard consists of longitudinal and transverse arms 2, 3, 4t and 5. The longitudinal arms 3 and 5 contain a guideway in which is slidingly mounted a bar 6 the front endof which constitutes the last engaging member of the toe end feeler. Upon the front endof the bar 6 is located a' block 8 which constitutes the sole edge engaging member of that feeler. The last engaging member 6 and the sole engaging member 8- are each tapered to narrow bearing faces at their work engaging ends. The block has a longitudinal slot and is con-fined in adjusted position by a binding screw 10 and a cap plate 12 which has depending flanges embracing the' block and the bar 6 and the forward end ofwhich is extended to form fingers that overlie and en gage the margin of the sole.

' The transverse arms 2 and. 4 pivotally support anglelevers lp the frontarms of exact are bent iuwaruia to" engage the @01 ners of the toe substantially normal to its curvature at those points, said arms constituting the last engaging members of the corner feelers. These feelers are constructed like the toe end feeler above described.

The other arms of the angle levers 16 are overlapped at their ends, the upper one being provided with a slot through which extends upwardly a stud 18 carried by the lower arm. A tension spring 20 extends from stud 18 baekwardly to a stud 22 in the rear end of the bar 6 and is adapted to hold the three feelers in normal proximity. The lower end of stud 22 depends below bar 6 and acts as a stop to limit forward movement of that bar.

One of the levers 16 has an areuate slot through which a binding screw 25 extends and is threaded into the arm 4: of the machine head. This binding screw can be used if desired to hold the side feelers in any detached to an insole tacking machine in such position upon the last bottom.

position that it can be engaged by a shoe presented to the nozzle 30 of the tacker, and the operative takes a last and a turn shoe sole in his hands, places the sole with its toe end extending beyond the toe end of the last farther than the normal projection and thrusts the work into the feelers, being guided as to vertical position by the fingers 12. As the work engages the feelers they center the toe of the sole on the last and push it back to where it presents the normal projection beyond the edge of the last for which blocks 8 are set. With the work in this position at the toe the operative positions the heel end of the sole on the heel of the last and then presents the shoe to the nozzle 30 of the insole tacker from which a tack is driven by driver 32 into the forepart of the sole for securing the sole in adjusted The shoe is then shifted and a second tack driven into the shank to secure the rear part of the solo in position. Instead of combining the sole locating apparatus with a tacking machine as above described so that the apparatus can position and hold the sole while the tacker fastens it, many of the advantages of this invention may be obtained by locating the apparatus more remote from the tacker where the operative will first present the work to said apparatus and then transfer the work to tacking position while holding the sole in proper location on the last. Alternatively the last may be supported in operative relation to the sole locating apparatus and the tacking performed by hand.
