To all whom it may concern:

Be it known that I, LELAND B. WHIPPLE, a citizen of the'United States .residing at Rochester, in the county of Monroe and State of New York,have invented certain.

Improvements in Lasts, of which the following description, in connection with the accompanying drawings, is a specification,-

Lasts of this type are much. subject to criticism because of lack of strength 'an'd rigidity, and it is a principal object of the invention to provide a last which will secure all the advantages of lasts of this type w thout bein subject to thesedisadvantages,

invention resides in a. n'0vel organization of last parts having a dividing cut comprising a re-entrant angle and a 'slmple and inexpensive link-bonding me :hanism".-v

- 'This and other features of the invention, COIIlPl'lSlIlg various arrangements and com-*- binations of parts will'be understood from the followin description which ,shows a referred em odiment or, the invention, seec'ted for purposes o f'illustrationand shown and a contact face extending from said cor- ..ner=downward and substantially rearward to the bottom of the last," and two non-par- 'allel links each pivotedtin both last parts arranged one above the other,- the lower bein the drawing in which,

Fig. l is a sectionviewof thelast in extended position; v v

Fi 2 is a'sectio'nal view showing the last in co lapsed positionay The-last has a fo'repart'lO- and a heel part 12, divided'b a cut which extends upwardly and forwar y, as-at 14;,to nearly the centerv .of the last,-then' extendsforwardlyas at 16, and then upwardly as at 1-8 on the foreom an intermediate point of the segment -,to the top of thecone.

In te mbnyw art. The heel part .secant face 20 extends The bondingmechanism "comprises fourrivets 22, 24, 26,28, the rivets 24, 26 being located approximately-in-the same horizontal plane, while the rivet 28 is considerably higher than the rivet- 122. These rivets are jolned by twolinks 29, 30,'as shown, the up per link 2? having a 111 32 arranged to enga e ai-spring 34-, seate' 1n a hole 36..

. en the last-is extended, the side 37 of the re-entrant an le 38 rests upon the sur face 16 and aflfor a firm bearing against torsional stresses, such as are imposed by the leveling machine. At the same time, the last 'is easily colla sibleby pressure and without the use; 0 special tools or jacks.

The sloping cut14 permits the lower secant face onthe-heel part to pass freely over the corner-on the forepart formed by the cuts 14 and 16, without}. binding, as shown in dotted lines in Fig. 2. v v

The last described is simple in construction, not easily put out of order, and-cheap to manufacture. It is at the sametime rigid Accor ingly, a principal feature of the shoe-making and is easily collapsible'when it v isdesired.to' .w'ithdrawthe shoe.

against the stresses met with in machine -,,-.1EIav ing fdescribed'my invention, what I' claim-as new and desire to secure by Letters jPatent'of theiUnited States is A diyided last having a cut comprising a re-entrant angl of approximately 90 in the 'he'el'part,.a corner on the; fore art, fitting into said angle-whenthe last. 1s extended,

part upwardly and forwardly past the saidreo corner on the forepart to collapsed position. I ereof I' have signedjmy' name to this speclfication. I Y LELAND B. WHIPPLE.
