Description

withdrawn it is possiblo to lift tho heel portion of tl1e last to with lraw the main portion in advance of the separable side section.

lt will be observed tl1at in both forms of 1 last, the transvorse cut is back of tl1e ball portion so that tl1o longitudinal cut extends through tl1e Iniddle portion f the ball in order that the width and consequently the girth of the ball shall be diminished as tho sections am separated. By this principle of construction any dosirablo dogree of oon traction of the ball may be secnred to completely avoid the breaking down of the waist. As the sections am capable of co1npleto separation, the sido section remaining 111 the shoe while the main section is withdrawn, there is no limit Within practical requirements of tln= amount of contraotion atta1nable.

What we claim is l. A last wl10se sectional foro part is di vided vertically l y longitudinal and transverse cuts, tl1o main section being providod with forwardly projocting holding pins ofi to oxtend into lonunequal length arranged gitudinal recosses formal in tho side section parallel to the longitudinal dividing plane to all'ord a sliding and rotaining ungagoinent betwcen. tlie l1\\'0 seotions, snhstantially described.

2. A last having a soctional foio part di vided -verticallj by longitudinal and transverse cuts tho main section l eing p1'0Vided pin oxtend1ng with a forwardly pro ecting parallel t0 tholongitmlinal dxvision for the greater part of the distance to tl1o. toe .tl1o side soction l oing pfovi led with a cof1es;p0nding longitudinal rocoss fo1 tho part '0f its lellgtl1 to roceive said pin, and

greater l means for prevonting tl1e sicle seotion i1om tunung about the holdmg g as desmibod. 3. A last having a sectional loio vided vertically by longitudinal and transverse.cnts into two sections and longitudinal pins of uneqnal lengtlx oxtending parallel t-o alle plane of longitudinal division to fonn a sliding engagernont ancl snpport betwecn tlm two sections while p'tnmitt1ng thoir separation, substantially as desoribed.

=l. A last having a sectional fore pait divided vertically by longitudinal and ti'aiis- Verse outs, a longitudinal pin sooured in tl1v transverso face of the.nmin scction and extending for tho groater part of the distanco to tho-too parallel to the longitudinal plane ol7' division, the side soctio'n boing provided with a corresponding 1ocess to receive said pin. so as to be supported tliereby tl1e g1cater pa1t of its longth and n1oans tonding no1= mally to separate tl 1e sevtions, aubstantiall; as dosuribed.

5. A last elnlnacing a sectional forie palt divided vortically by transverse and longitudinal cuts into two sections l1aving longit.n .linal sliding ongagement with nach othel, the n1ain section being provideil with a sepapart (lira'ble instep block cut away cl1ioll y l1n tlm j side op osite 120 tl1e sliding side seotion sul j st-antially as described.

In witness whereof, we havo subsmihod the above spocilication;
