Prior to attaching soles to shoes it has been
customary to trim the lasted over portions of
the uppers and to smooth out the wrinkles there
in by beating the'shoe bottoms in order that they

against the roll thereby to control the amount of

and inexpensive means for heating the roll.y
These and other features of the invention are
illustrated in the accompanying drawing, de
scribed in the following detailed specification,
and will be pointed out in the claims.
In the drawing,
Fig. 1 is a, plan View, partly in section, of a
machine embodying one form of my invention;
Fig. 2 is a detail View illustrating the opera
tion of the shank pounding roll; and
Fig. 3 is a detail view illustrating the opera
40 tion of the forepart pounding roll.
As illustrated in Fig. 1 the machine comprises
a horizontal shaft Ill mounted in bearings l2 in
a frame I4, there being a pulley I6 for driving a
The shaft carries a forepart pounding
45 roll I8, a shank pounding roll 20, and a trim

is generally cylindrical in shape but has its pe
riphery slabbed off to form a plurality of fiat

a spring 38 mounted upon a rod t@ the ends oi'
which lextend through openings 152 and til in
the levers. This arrangement is such that the 2
spring is operative to force yokes 33 toward each
other moving the friction members 3@ inwardly
into frictional engagement with the walls of the
recesses in the roll.
To regulate the pressure exerted by the fric
tion members against the roll and, consequently,
the amount of heat generated, there is provided
a nut ¿i6 on a screw threaded portion 48 of the
rod 40. This nut can be readily adjusted to
vary the pressure of the spring 38. The rod ét*
also carries nuts 5i! which can be adjusted along
the screw thread 4S to take up the slack between
the two ends of the levers 34.
The shank beating roll 2li is of similar con
struction to the roll i8 in that it has a plurality 40
of flat work-engaging surfaces 52. This roll,
however, is smaller in size than the roll »i8 and
ordinarily need not be provided with any means
for heating it.
The trimming roll 22 at the end of the shaft
il)k may be of any suitable construction such as
that of a type which has come into general use
and which comprises a felt roll having a sand
paper strip secured to its periphery. Such a
roll is adapted for use in removing surplus upper 50
