due to the use of such tacks.

Another object of the invention is the pro- -vision of the last securing means which is capable of use in connection with hinged lasts of all descriptions, the invention providing a'convenient means for securing the last in position without injury to .either the last, the shoe or the lining. r

Figure 2 is a view similar-to Figure 1 showing the last in position for removal from the shoe. j

Figure 3 is a detailed view of the securing means which is carried bythe last. f

Referring to the drawings in detail, there is illustrated a last which is formed ofsecone end 14: of which is pointed to provideV a spur. This vpin operates or slides in an upwardly and rearwardly; inclined opening 15 which is provided in the last section 11 and extends centrally and longitudinally of vthe last.

having one end secured'to the rear end of Y the toe sectionat a point directly'y beneath and spaced from the pivotal'connection and adapted to lie within' the passage, whereby,

when the sections are in normal position the free end of the pin will be .projected beyond the outer end ofV the heel sectiona'nd re` tracted when the sections are moved relatively upon their pivot. 2. A shoe last comprising va toe` section,l

vla heel section pivotally `secured to. the tee section and havingan upwardly yand, rearwardly inclined passage extending from 4its front to its rear end and a eXible pin hav-' ing one end secured to the rear Ven d of the yond the outer end of the lheel section and 'first sectionv at a point directlybeneath and i ino retracted .when the sections are moved rela-j tively upon their pivots.
