10 Claims. (Cl. 12-50.5)
This invention relates to means for removing worn
heels from men’s shoes in preparation for placing a new
one thereon, and more particularly to an improved de
vice of this sort by which the removal or stripping of the
worn heel may be accomplished with exceptional ease and
effectiveness.

The improved heel stripping device of the present in
vention is generally characterized by a lever arrangement
for actuating the stripping means at substantial mechani
cal advantage and in progressive or successive increments
so that the heel stripping operation may be controlled
nicely, while at the same time allowing it to be performed
quite rapidly. In addition, the actuating lever arrange

ping action as indicated in FIG. 4; »and the pairs of yoke

control the reciprocation of the stripping means. For
this purpose, one pair of yoke legs 54 has connected there
at a rack bar 58 extending downwardly past the previous

for engagement at its lower end by a ratchet mechanism
of -a stripping operation, or to relieve any jamming that
may ocur on occasion, or to restart a stripping operation
if need be.

By the foregoing arrangement, the stripping means
formed by the series of stripping blades 46 is disposed on
the frame structure 10* for reciprocation in relation to
the anvil at 42 between a raised position such as is indi
indicated generally by the reference numeral 60. This
30 ratchet mechanism 60 comprises a housing formed by a
