This invention relates to trimming machines
and more particularly to machines for operating
on partially pulled-over or lasted shoes to prepare
their toe ends for cement lasting. More speci?
Cl cally, the invention is concerned with the prob~
lem of severing a strip from the lining at the toe
of a shoe, to the end that the pleats, when the toe
is subsequently lasted, may not be too bulky and
the margin of the upper may lie in contact with
10. the insole instead of being separated therefrom
by the lining.

driven to feed the work.. Moreover, as herein
shown, the other shearing member is a small ro
tary disk the perimeter of which is preferably
provided with teeth thatoperate with a shearing
action without tearing or shredding the work. To
guide a partially fabricated shoe the machine is
provided with an improved trimming guide hav
ing a lip formed and arranged to project between
the inner layer and the perimeter of the insole.
In addition to the features above mentioned, the
illustrated machine is provided with other novel
and useful features by which the feeding of the
term “lining” will be used to include, for the sake
of brevity, such other elements as may be pro
vided to reinforce it,>for example, a-toe-box or
stiffener and a doubler. These usually lie be
tween the upper and the lining proper and in
many shoes they are secured to the latter by ad
hesive substance, by stitches or both.

no attempt has been made in Fig. 1 to represent

cordingly, the present invention provides a ma

crum 42. A stem 49 rigidly related to the pawl
45 is arranged to turn in a bearing formed in the
rocker 46 and is retained therein by a short length
of spring wire 5|] that serves not only as a keeper
The trimming machine shown herein is pro
15 vided with a small ?at disk cutter 20 arranged
to operate in confronting relation to the insole
of a shoe. The cutter is preferably provided with
peripheral teeth arranged to operate in shear
ing relation to a shearing edge 2| formed on a
20 rotary spindle 22 in consequence of forming a
peripheral groove 23 in the spindle near its lower
end. Below the shearing edge 2| the spindle is
tapered abruptly to provide a cone-shaped head
or extremity 24 adapted to project between the
25 free margins of the upper and the lining and to
de?ect the margin of the upper away from that
of the lining. As represented in Fig. 4, the cutter
20 has the appearance of a circular saw, but its
direction of rotation is such as to cause its in
30 clined edges rather than its radial edges to oper
ate with cutting effect, since the inclined edges
are better adapted to operate with a shearing out
without shredding the material to be severed and
without feeding the work too rapidly or with too
35 much force.
The cutter 20 is affixed to the lower end of an
extension 25 of a shaft 26, the extension 25 being
bored and tapped to receive an attaching screw
21 having a left-hand thread which, by reason of
40 the direction of rotation of the shaft 26, has a
tendency to tighten the cutter when in operation.
40 and is maintained in contact with the eccentric
but also as a spring to maintain the. pawl in con
tact with the ratchet-wheel. One end of this 10
vwire is inserted through a hole in the stem 49
and the other end is formed to engage and par
tially surround the counter~shaft 42.
The assemblage comprising the work-feeding
spindle 22 and the above-described parts for com 15
municating rotation to it from the eccentric 40
also includes a two-part housing comprising co
operative bearing members 5| and 52 rigidly con
nected by screws 53. This assemblage is movable
intact toward and from the shaft 26, to the end 20
that the margin of the lining may be readily in
serted between the spindle 22 and the cutter 20
when the assemblage is retracted. For this pur
pose, the bearing member 52 is arranged to slide
in a horizontal bearing provided by a grooved cap 25
55 secured to the frame 3| by bolts 56. A pin 51
af?xed to the slide 52 projects laterally through
and beyond an opening 58 in the cap to form
connection with a link 59. The other end of this
link is pivotally connected to one arm of a bell 30
crank lever 66, the fulcrum of which is indicated
at 6|.
The other arm of the bell-crank lever car
ries an adjustable stop-screw 62 and is connected
to the upper end of a rod 63 that extends down
wardly to a treadle (not shown)‘ mounted at the 35
base of a column 64 on which the head 3| is
mounted. A compression spring 65 surrounding
the rod 63 normally maintains the work-feeding
spindle 22 in its operative position shown in Figs.
1, 2 and 4, the lower end of the spring being 40
seated upon a stationary abutment 66.
A boss 61
The extension 25 also carries a freely rotatable
roll or sleeve 28 supported thereon by the cutter
20. This roll is arranged in cooperative relation
45 to a grooved or knurled peripheral surface 29 on
the spindle 22, the latter being driven at a slow

stop-screw 62 to limit the extent of retraction of
the slide 52.
The machine is also provided with a trimming 45
guide (Figs. 2 and 5) comprising a plate 19 of
speed to feed the, work by» its engagement with
the margin being severed, and the roll 28 serving
to pinch the margin sufliciently to insure a feed

The shaft 26 is arranged to rotate about a ver
tical axis in a bearing 38 provided by a head or
frame 3|. Any preferred means may be pro
vided to drive the shaft 26. As herein shown, the
55 shaft is provided with a pulley 32 to which rota
tion is transmitted from the driving pulley 33 of
an electric motor 34 by a belt 35 that runs over
idle pulleys, one of which is indicated at 36.
With considerable latitude in regard to the rela
60 tive diameters of the pulleys 32 and 33 the cutter
20 may be driven at various speeds from about
800 R. P. M. to about 2000 R. P. M.
The organization herein shown provides for
driving the spindle 22 at slow speed with rotation
65 derived from the shaft 26. For this purpose, the
shaft is provided with a circular eccentric cam 40,
each complete rotation of which turns a ratchet—
wheel 4| a distance corresponding to the length of
one tooth of the ratchet. This ratchet-wheel is
70 affixed to a countershaft 42 by which rotation is
transmitted to the spindle 22 by pinions 43 and 44.
The ratchet-wheel receives its motion from an op
erating pawl 45 carried by a rocker 46 arranged
to oscillate on the shaft 42 which serves as a ful
75 crum.
The rocker also carries an anti-friction
‘H is rigidly secured by a rivet 12. A holder '13 is
provided with a socket in which the stem is ar
ranged, and the socket portion thereof is divided 50
by a kerf 14 and provided with a clamping screw
15 by which it may be contracted to grip the
stem. Two holes 16 are bored through the holder
13 to receive screws 11 by which the holder is
secured to the frame 3|. The lower portion of .
the plate 10 is bent to underlie the cutter 20 and
its attaching screw 21, and the extremity of this
portion of the plate is bent down to form a lip 18
arranged to project between the lining and the
perimeter of an insole l2 as shown in Fig. 1. The 60
lip 18 is thus arranged to guide a shoe by contact
with the perimeter of the insole while the hori
zontal portion of the gage lies on the face of the
insole to maintain the shoe at a level slightly
below the level of the cutter.
Assuming that the described machine is to be
used to out off a strip of all the lining materials
at the toe end of a shoe in the condition repre
sented in Figs. 1 and 6, the operator will ?rst
depress the treadle to retract the feeding spindle 70
22 from the cutter 29 and will then present the
shoe to the trimming gage in a position that will
enable the conical head 24 of the spindle to enter
between the inturned margin of the upper and
the lining materials at the point indicated at a 75
