T all whom zit mfr-y concern.-

Be 1t lmownthal', I, ERNEST A. EASTMAN, a citizen of the United States, residing at Ch icago, in the county ol' Cook and State of Illi nois, have invented an .'l'rnprovementin Lasts, of. Winch the following description, 1n connectlon with the accompanying drawings, is

a speciication, like letters on the drawings tor and have no tendency n v forepart of the shoe.

v heel of the representing like parts.

It is a well known fact that almost all shoes as they become Wornv run over on the outside to some extent, so that the foot hangs over the sole along the outside portion of the In other words, shoes usually tread sidewise, as it is termed. by last makers, so that instead of the vamp or upper remaining centrally positioned over the sole as it should, it gradually-shifts or bulges outwardly along the outside of the foot, the result being that the Weight of the wearer is gradually carried more and more to to the outside of the shoe, thereby wearing the sole and frequently the heel unevenly.

My invention preventsthis tendency of shoes by constructing the last insuch a inanner as to compel the shoe to throw the foot ol" the wearer centrally along the sole so that the foot hugs the inside of the shoe exactly as it should. The heel end of the counter is the Amost rigid part of the shoe, the entire counter beingpurposely rigid for supporting the foot and maintaining the shape of the shoe. Hence all the give or yield must come onY the forcpart. That is to say, theheel portion-ol' the shoe is not only arbitrary, but it remains unalterable acorn-ding to' its original shape and constant-tion. Also the heel ol' the foot Controls the position of the foot, especially ol' the toe portion or foropart of the foot.

M y invention. takes advantage of the foregoing two facts by so constructing the heel and locating the center line of the back of the crooked last that the shoe ronstruoted thereon has its ounter portion ol heel part so shaped with relation to the rest oi' the shoe that it positionsthe heel part so es to eonlpel the l'orepart 'lo tread in the Conbatevor to work 'over to the outside and run over thi.. .shoev of the counter guides or oonol' the shoe, as it is the only .rigid and hence by trois the rest part that absolutely giving it the right shape and direction the i I l l l l l v that shoe in the right direction to direct or push the foot to the inside or center as distinguished from the old construction. I accomplish this result by swinging the een ter line of the back of the heel toward the outside ofthe last, and buildingJ up the outside of the heel beyond said. center line, taking oli' the inside of the heel at the opposite side of said center line, and preferably building up the last at the inside ust'at the front oi the heel, thereby pushing forward the outer end of vthe width line of the heel so that when a line is drawn from the heel to the toe through said centerline at the baul; of the heel perpendicular to the width line, it comes at or inside of the big toe. This gives a strong tendency to the foot to move toward the inside, so that the shoe is broken in in that Way and as it grows 4old the upper will not push over to the outside but the shoe and user get the benefit of the iull tread of the sole.

In the drawings I have illustrated my invention with reference to several of the leading types of crooked lasts (as distinguished from straight lasts).

Figures l, 2, 3 and Li are similar bottom plan views of different forms of lasts or patterns, showing by reference to dotted lines in what respects they diller from the old construction.

My invention relates to crooked lasts, which are those commonly usedv at the )resent day, as distinguished from slipper lasts and the old fashioned "straightJ lasts.

Referring to the (.lrfnvings, Fig. l shows a swing last, t. e., one forni of 'crooked lasts, sometimes oalled the walkinf fast" last. 1he dotted curved lino shows ow this last has )reviously been constructed and the lull lines indicate my construction, from whioh it will be seen that the lines of the forepart ay coineide in both constructions lroni the toe back to near the heel, but that the conter lino oli the back olE thel heel has been sbil'tod toward the outside I'ronl the point .I to tho point 2- and that the rdar outside portion has been built up at 3 and at the opposite or inside rear end has been taken oll. at Il, thereby :banging the width line 5 so its outerond (i is forward oll its old position, the previous width line boing indicated at 7. At and just in front ol' the width line the .in de e? last builtiip at and the opposite side is taken olll at '9. rlhe result is that the center line o'f the last, i. e., the line which extends from the center line 2 et the nac-ik: of the heel perpendicular to the 'width line falls on the inside of the last and extends 5 out slightly to the inside of the toe, as shown clearlyT by the center line 10. The line 11 is the previous center line of the last as it has heretofore been constructed, I have siniilarly designatedI the corresponding lines and io lust portions in each of the figures andi-have also drawn lines parallel to the center line of the last at a distance therefrom correspondine; to haltl of thc length of the width line. By my newconstruction the outside line 12 1.5/ passes toward the toe just at the outside thereof, and the inside line, if drawn, would not touch the last, but would pass entirely to the inside thereof, whereas in the old construction just the opposite is the case, and 2o only the inside line appears, as indicated at 13, excepting in c very extreme styleJ Where the' outside line 14 just touches the extreme outside oi' thc forepart.

From thc ahoveexplanatioirit will he nnderstood that my invention relates to a last in which the too has an inward swingr toward the inside of the lust or loot, and resides in i shifting to the outside the truc center line of the hack ol,E thc heel and correspondingly changing the contour oi the `outside and inside of the heel so that the point 2 will in inet 'he the true. center line, i. e., will come at the rear center of the cuiviitnres at either side. The result is that`in use the sti arhitrery counter of the shoe is so shaped and posie tioned, corresponding to the last, that it compels the loot to rest properly in the shoe. Accordingly no riinninp; over ol the shoe can take place, tho'sole is oblig-cd to Wear uni- 4.o fornily throughout the entire width of the tread and the wearer has comfort ns the joints ofhis Vtoot arc'not pressed against the sides ol' tho shoe Vin an unnatural 1n n-nncr.

'lho width lino is defined :is that transversc lino which intersects thc ide-st part ci' the heel at (-,orrcspo'mlingr distances from tho hack ond ol' the heel alongthe opposite identical sirio-curves at tho sides o1' the heel, and I it is found hy folding' exactly together the 5o opposite rear sido edges ot' a paper heel-pat tern and striking, a line at a right angle from the feld er to the widest )oint of said coinciding side-curves from the endet' the heel. The center line of the last corresponds to said 'fold or'crease, and the center line of theheel isthe vertical line on the heel of the last which intersects the rear ond of said fold or crease,

Having described my invention, what I clailn as new and desire to secure by Letters Patent, is,

l A crooked last for boots and shoes7 having the center line at the back of the heel located toward the outside of'the last suiiciently to bring the center line of the last, which extends from said center line ofthe hee'l, perpendicular to the Width line, at or inside-the toe of the last while yet maintain ing the crooked formation of the last as distinguished from a straight last.

2. A. crooked last for hoots and shoes, having the outside rear end cir the heel built up and the inside rear end of the heel taken oi, so as to render the crooked last abnormal but not straight and to tiring the center line at the rear ot the heel toward the outside snHiciently to swing the center line of 'the last 4nearer to the inside of the iorepart than it is to the outside.

3. A crooked last for boots and-shoes .in which the toe has an inward swing, having its heel so shaped that the center line passingr through the middle of the width line, and a line parallel thereto intersecting` the outside end oi said width line cnihrace the toe ot' the last hetween their forward ends.

Ll. A crooked last for hoots and. shoes in which the toc has an inward swing, having its heel so shaped that a line from thel inside end of the width line projected forward parallel to the centerline of the last lalls outside of the inside surlace of the forepart of' the last.

lntostiniony \\'h -reol, ,l have signed my nii-lire to this spccilication, in the presence of two snhscrihing witnesses.
