SHOE aszr.

Application filed January 10, 1925. Serial No. 1,888.

This invention-relates to a method of and apparatus for lasting McKay shoes. In the usual process of lasting this type of shoe, it is customary to tack the inner sole to the last at the fore part and shank of the last. After the shoe has been lasted, it is necessary to remove these tacks and although the tack in the fore part of the last presents no great difliculty, the tack in the shank is generally covered by the upper and can sel- 'dom be removed without disturbing the lasting.

To the end, therefore, of avoiding the objections to existing methods of lasting Mc- Kay shoes, I have devised my present invention. According to it, I eliminate the tack at the shank of the innersole, and instead provide the metal bottom of the last at this point with a pair of oppositely disposed shoulders between which the inner sole is laid and by means of which it is ac curately and securely held in place without in any way interfering with the ordinary operation of lasting the shoe.

The method of practicing my invention, together with apparatus for carrying out the principles thereof, are described and illustrated in the accompanying specification and drawings, and the characteristic features of novelty are particularly pointed out in the appended claims. Throughout the specification and drawings like reference numerals are correspondingly applied, and in the drawings:

Fig. 1 is a bottom plan view of a McKay shoe last equipped for the practice of my invention.

Fig. 2 is a similar view thereof showing the1 innersole removably clamped thereon, an

Figs. 8 and t are sections on the lines 33 of Fig. 1, and 4tt of Fig. 2 respectively.

I have indicated at 1 the usual meta-l bottom of a McKay last of standard type and at 2 an innersole. The innersole is temporarily tacked at 3 to the forepart of the last, in accordance withthe usual practice, but instead of temporarily tacking the innersole t0 the last at the shank thereof, I have provided the metal bottom of the last in the region of the shank with a pair of upstanding ribs or shoulders 4 between which the shank of the innersole is accurately and securely held in place on the last. The shoulders i need extend only a relatively short distance longitudinally of the shank and may vary in height according to the thickness ofthe innersole being used. They are preferably arranged oppositely to each other and are spaced apart a distance slightly less than the efiect-ive width of the innersole at the shank so that the innersole may be pressed past them in positioning the innersole on the last and when engaged therebetween will be positively retained against lateral movement on the last. Preferably the free edges of the shoulders 4: are slightly inturned, as indicated at 5, so as to more effectively engage and retain the innersole in position.

With my method of novel form of last, therefore, all possibility of disturbing the innersole is avoided, because the innersole is clamped solidly by the shoulders 4 to the last, and all possibility of disarranging the upper after the lasting is completed and the lnnersole is ready to be disconnected from the last is eliminated, because the innersole can be readily lifted out of the clamp provided by said shoulders. When the innersole is tacked at the shank, as in general practice, it is difficult to dig out the tack, especially if such tack be covered by the upper, as is generally the case.

Various modifications in the method of and apparatus for practicing my invention may obviously be resorted to within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. Means for temporarily positioning an insole on the metal bottom of a McKay last with its edge contour in predetermined relationship to the edge contour of the last bottom, comprising a plate mounted on the last bottom to extend transversely thereacross at the shank of the last and having oppositely disposed upstanding ribs located at the lateral edges of the last bottom and betweeirwhich ribs the insole is adapted to be pressed from above and by which ribs it is frictionally retained in position on the ast.

2. Means for temporarily positioning an insole on the metal bottom of a McKay last with its edge contour in predetermined relationship to the edge contour of the last bottom, comprisinga relativelythin fiat plate mounted on the last bottom to extend trans- V81S6lj thereacross at the shank of the last, said plate terminating at its ends in a pair of oppositely disposed upstanding ribs located at the lateral edges of the last bottom and between Which ribs the insole is adapted to be pressed from above and by which ribs it is frictionally retained in position on the last.

3. In a last for McKay shoemaking having a bottom adapted to receive a toe-tacked insole, a shank retainer for temporarily securing the insole on the last bottom With its edge contour in predetermined positional relationship to theedge contour of the last bottom and includ'i n a pair of thin upstanding opposed lips between which the opposire edges of the shank of a vertically applied insole are adapted to be received and releasably engaged.

In testimony W iereof I aliix my signature.
