Likewise the positioning of an upper or shoe on the last may be effected by inserting the separated heel part in the upper or shoe, arranging this about the body portion and sliding the heel part onto the body portion. The heel part and body portion may be formed one with a rib and the other with a groove, the rib and groove being formed with inter engaging portions. A latch is provided for locking the heel part in its operative position on the body portion and a post on which the last may be mounted may include means for releasing the latch to enable the heel part to be slid off the body portion.
For use in the manufacture of shoes, the combination of a last and a last post, the last comprising a main body portion and the post having an upper end portion, one of said portions having a socket therein of a noncircular cross-section and the other portion having a spigot having a cross-sectional shape complementary to said socket and mating with the socket for locating and detachably mounting said last on said post, said last further comprising a heel part slidably mountable on said body portion for sliding a distance for removing said heel part from said body portion, a rib and a mating groove formed one on the body portion and the other on the heel part, said rib and groove when interengaged mounting said heel part on said body portion in slidable engagement therewith, said body portion and said heel part respectively having surfaces thereon which abut when said heel part is slid to an operative position, a spring latch secured on said heel part and having a free end movable to engage an abutment on said body portion when said heel part is slid to its operative position, and means for moving said free end out of engagement with said abutment for releasing said heel part for removal from said body portion.
