Ittherefore fol... tion of' so 'much lof la' 'lastlng machine lows that as the size of thel'ast diminishes equipped with' thecpil-esentyimprovements as f. a longer backward movement is'l required 1s necessary to present: for explaining this 'in *order to cause the heel band firmlyl toeminvention; Fig.' 2 '.is a perspective view' of b'race. the lshoe properly. There comes al( the heet'pin, audits bolder.' 110 The machine comprises toe lasting mechanism A and heel lasting mechanism B in a operative relation to which the shoe issustained by a toe rest C and a heel p in 2. The l heel lasting mechanism may correspond in its construction and mode of operation with that shown in said application which is embodied in a well known commercial form of lasting machine and is not necessary to describe here further than to explain that it comprises the heelembracing band Sinto which the shoe is drawn rearwardly by the engagement of the heel pin with the last.l

' that projects forwardly over the heel end of the shoe from one ofv the heel wipers. This vertical movement of the holder is effected by a lever 10 which is pivoted at its rear end to the slide 5 andv upholds the Vholder 4 by vits front end. f. This lever has an inclined face 12 which rests upon a yieldingly susi I tained screw` 14 and produces an upward tilting of the frontend of the lever as the slide is retracted, whereby ,the shoe is simuly taneously forced backwardly into its 'heel ranged in Fig. Lof the embracing band and uplifted against the gage 9.

The heel pin 2 is mounted inaccordance with this invention, nearer to one edge of the holder, as its front edge, than to the opposite edge and vthe 'holder ,is reversibly mountedin the-slide 5. 'This construction permits the holder .and in,l which are ardi'awin s to receive a large shoe, to be lifted out o the slide 5 and turned around and to be reinserted with the pin Vat the rear ofthe cente'r of the holderand nearer to the heel band for small lasts. By this provision for adjust-ment of the heel pin toward and :from uthe lheel j band a vwide range of sizes of shoesincludingfmens, womens and childrens may be 'supported in proper relation to the heel lasting instrumentalities of this machine by a single equipment, whereas a plurality of heel'pins and holders have heretofore been.

- required.

Provision is made for vertical adjustment of the heel pin by the screw 18 adjustably .carried by the lower portion of the holder '4 and resting upon the lever 10. The .heel

pin is mounted 1n thelholder by a longitudinal pivot pin that permits lateral tip ing of 'thepin for unsymmetrical lasts, or asts in which the pin hole is .unsymmetrically located so. that there is need to equalize the' strain as the last is forced backwardly into the band. The pin has oppositely inclined faces on its lower end which are engaged by a yielding centering plunger 19 which maintains the pin in a normal lateral position.

Having explained the nature ofl this in` vention and' described a preferred construe-j tion embodying the same, l claiml as new 1. AAl'lasting machine,- having in combination with' a heelembracing band, last sup'- porting means comprising, a heelpin and a .holder therefor a carrier for .the pin ,and

7. A lasting machine having in combination a heel band, heel lasting plates, a last pin, a carrier in which the'pm may be held in dii'erent positions, means for' actuating the carrier to pull the in into the band, and i means to lift the pin uring said movement ofthe carrier, said machine having 4provi-- sion for changingv the position of the pin to I vary its initial horizontal'relation lto the band and plates.A -1
