This invention relates to that class of ma
m chines forpressing cement-coated soles against
lasted bootor shoe uppers, in which the last
holding the ‘upper is rigidly supported and the
cement-coated sole is pressed against thelasted
upper‘ by an elastic bed, which is movable to
15 ward and from the rigidly supported last, and
is moved toward the last by mechanism con
against the plates, the springs being partially
contained in sockets in said block.
The trun- o0

head, i, which is adapted to slide vertically
