19 Claims. (Cl. 12-8.2)
This invention relates to shoe machines, and particu

of FlG. 4; and
FIG. 10 is a vertical section showing the relationship
of the last, upper, insole, yoke legs and wipers.
Referring to FIGS. l and 2, there are wipers 10 and

14 to move in a horizontal path forwardly and rearwardly,
and a shoe support comprising a toe rest 16 and a heel
pin 18 mounted on a carriage Ztl for movement vertically
to raise a shoe into a position to be operated on by the
wipers. The shoe support may be made substantially in
the shoe upper and the conformer.
