" 5 tain new and useful Improvements in Lasts,

'of which the following is a specification. Myinvention relates to that class of lasts 'whicharecalled divided or hinged lasts and are arranged toshortento facilitate their re- 'moval from, or insertion into the shoe, and. has for'its' objectto provide ad'ustment thr take up the wear'of theparts an to compel? -;sate for any inaccuracy in fitting up the.

parts, and especially to allow the samecon- :15 necting device to connect different toe parts to the same heel part or different heel parts to the same toe p'art and to this end'consists of, certain improvements which I will now describe and point out in the claims.

-In this embodiment I show my invention as applied to a last of similar construction to the one described in patent granted to me September 26,1899, No. 633,741, but it may be applied 'to other styles of lasts as will be z 5 readily seen. -In the above mentioned patent the links or members which connect the sections cannot be finished before they are in position as it is im ossible in practice b the resent method 0 manufactureto dril the oles in the'links and-in the sections of the last so that't he parts can'be afterward assembled, butit is found necessary that the hole for-the-pivotimeneend of oneof the /linksfiust be drilled after the other parts are 5 all fitted. In the old construction it any of the arts are chan ed it is necessary to dis- ."car one'of the liriks and put in a new one l that ma be fitted to the parts as reassembled, im there is no way to take up the wear or stretch of the parts. It is well known that the changes in'the shae or style of lasts, owing to fashion, are usual yinade in the toe,

and that in a great variety of lasts the heel p art will be found to be the same shape.'-

or this reason a connecting device which can be adjusted to different toe or heel parts without further fitting is very desirable, as in that case a new toe part can be made and used with the same heel part and connecting tainin these is very greati' 4 Int e accompanying draw' 'gs,-for1ning a the connecting links'the saving made in rebar.

As most of the labor and, expense of making lasts is in forming the heel parts and ter the wood a last in operative position containing-.my improvements with a part broken away to show a longitudinal vertical section through thecenter of the last extending from the heel to a point forward of the space occupied by the connecting device. Fig. 2 shows a side view of the metallic heel seat of the last with my adjusting bar. Fig. 3 is a frontview' of the metal heel seat shown in Fig. 2. Fig. 4 is a perspective view of my curved adjusting Fig. 5 shows a view of the adjusting screws which connect the-bar tothe heel seat.

Fig. 6 shows a section of a toe part containing a modification of my adjusting bar. Figs. 7 andS are other views of the bar and'link shownin Fig. 6. r r

V a is the toe part of a last divided transversely by the linel m, and?) the heel section.

0 is a metal heel seat which extends from the face of the section far enough back tocontain the connecting device and jack spindle hole d and extends from the top to the bottom of the last. This heel seat contains the recess a in which the connecting links e and "f work. The link e is pivoted or articulated at one end to the toe section a in the slot 6 by the ivot pin or rivet g and at the other end to the link 7'. One endcf the link fis pivoted to the link (2 and theother end to v the adjustable bar 7a The heel-seat c has a se mental slot 71,1 through the wall on each si e of the recess e which slot extends from near the bottom of the last upward and forward to a point beyond the point at which the link f is to be pivoted. .At the lower end of the slot h is the adjusting screw 7L threaded to the heel seat, and threaded internally for the screw h. The forked bar h is fitted to the slot h with the base of the fork resting on the screw it and the screw and bar secured together by the screw h*. The sides of the fork and the walls of the heel seat are about the same thickness and the fork ex- 100 n fitting up my improved last the metal 1. 5 work is all finished and assembled before connecting with the wood art of the last.
