With these and other objects in View, as may
hereinafter appear, the several features of the

extremely accurate and eñicient means for pro

to the shape of the templet. In order to adapt
this principle of a templet guiding means for
commercial use, various attempts have heretofore
been made with a single templet to cause the
shoe operating devices to follow any one of a
plurality of predetermined contour paths about
the sole margin of a shoe supported in predeter

ited application in View of the fact that separate
templets must necessarily be supplied for each
length and style of shoe.
It is a principal object of the present invention
to provide guiding means cooperating with a

the position of the templet roller with relation
to the trimming cutter'for different lengths of
shoe of the same width size have been plotted
for a large number of positions in the transfer
15 of the point of operation around the shoe.
The automatic edge trimming machine dis
closed in the drawings a-s embodying in a pre
ferred form the several features of the present
invention, comprises a base 29 on which is sup
ported an edge trimmer head 22, a housing 24 for
the stop motion of the machine, together with
a shoe supporting jack 25 and the various sup~
porting and controlling mechanisms therefor.
The edge trimming devices, as best shown in
25 Figs. 1 and 5, consist in an edge trimming cutter
28 of ordinary description which is supported
on a downward extension of the armature shaft
Sil of an electric motor 32 rigidly supported on
the head 22.
The shoe supporting jack 26 comprises the toe
30
supporting arm 21 which forms an upward eX
tension of a jack spindle 29, and has mounted
thereon the toe rest 3| and the pivoted heel
supporting arm 33 and heel lpost 34. The jack,
35 as thus far described, is substantially similar to
4,0,
jacks of this general description well known in
the art, and is arranged for operation in the
usual manner, in which the positioning of a
shoe and associated last on the heel post with
the jack in open position operates to close and
lock the jackwith the toe in gripping engage
mentl with the toe rest 3|. The construction and
inode of operation of the jack is substantially
similar toI that disclosed in the patent to Morrill
No.`

4:5.
The jack disclosed in the drawings is also pro
vided with a templet guide at which is rigidly
secured to the toe rest 3|, and extends around
the shank and forepart portions of the shoe. It
will readily be seen that the templet supported
of the hand lever 44 operates to straighten the
toggle connection 52, 54 against the pressure of
the tension spring 56, and move the gripper levers
38 and 40 into gripping engagement with the
heel portion of a shoe supported on the jack.
This gripping engagement is maintained by
means of a ratchet locking device including a
spring-pressed plunger 55 supported in the han
dle of the lever 44 an-d arranged for engagement
with the teeth of a rack on the heel supporting
arm 33. It will readily be seen that the heel
gripping devices constructed and arranged as
above set forth, will operate to position the heel
portion of the shoe laterally to bring the center
line of the heel into the same position irrespective
of variations in size or width, so that the shoe
will always be supported in an exactly predeter--
mined relationship to the templet guide 36.
The mechanism herein disclosed for supportingî
and moving the jack to transfer the point of 20)
operation about the shoe, is substantially similar.

this movement of the roller 90 from the normal
position, which may be taken as its position as 35
determined by that of the feed lever B0 during
the operation at the toe, is determined in accord
ance with the length of shoe being operatedr upon
by an adjustment of the position of the pivot
block |08 in the track | I0. It will readily be seen
that when the pivot block |08 is located exactly
over the pivot H2 of the feed lever 60, no move-ev '
cam shaft in accordance with the size of the shoe » ment is imparted to the templet roller 90, so, that

.The arm 'Ni is moved into thelproper '
position by a longitudinal. movement of the con

of a pin 02 on` a‘forward extension of the lever
10 ywith one of two vinclined surfaces formed on
the end of the bar 'l5 remote from the arm l5,
this engagement taking place duringthe forward
movement of the bar 'i5 as the machine is started
into operation by the depression of the starting
treadle.
In carrying out the present invention, a length
size grading device is provided which operates to
control the positionof the templet roller 90 with
relation to thetemplet guide 3d during the trans
signed for an 8C shoe. For operation upon suc-
cessively larger length sizes of shoes, the pivot
block |08 is moved rearwardly corresponding
amounts which are gauged so that when the ma 5.0
chine is in starting position for operation upon
a shoe of the designated size, the templet roller
90 is' moved a corresponding distance to the right‘
to engage always the same point on the templet
36, as illustrated, for example, in Fig.` 3, showing 55
the machine in starting position for operation
upon an `11C shoe. The movement of the feed
lever |50 during the subsequent operation about` I
the shoe, will cause the templet roller 90 tobe

ing engagement of a spring-pressed plunger |20
when the adjusting slide block | |4 is located in
in any one of a number of holes |22 in the feed
lever 60.
The plunger |20 is supported within
a post formed on the slide block ||4, and is pro
vided at its upper end with a manual knurled
control knob |24.
A compression spring |26,
coiled about a reduced portion of the plunger,
10 ltends normally to maintain the plunger |20 in
locking engagement with one of the holes |22.
In order to cause the templet roller to follow
exactly the contour path about the shoe required
for each diiîerent length size of shoe, it has been
15 found necessary also to provide means for mov
ing the templet roller forward and back. This
forward and back adjustment is controlled by
means of the length size adjusting mechanism
above described, as determined by the setting of
20
.the adjusting slide block ||4, and by means of a
cam |30, hereinafter referred to as the angular
cam, on the pattern cam shaft 58 of the machine,
through a sun and planet gear mechanism to be
described.
25 _ .l Referring specifically to Figs. 12 and 13, the U
shaped lever 98 is pivotally supported by means
of two pivot pins |32 within a second U-shaped
lever |34 which is in turn supported by means of
pivot pins |38 within a third U-shaped lever |42
30 carried on a stationary pivot |44. As will read
ily be evident from the drawings, the fulcrums
for the levers 98 and |34 are only slightly out of
alignment with relation to the pivotal support
96 for the rear end of the templet roller support
ing arm. 92, so that relatively small forward and
back movements will be imparted thereto by the
actuation of either of these levers. It Will be
noted also that the actuating connection for each
of these levers 98 and |34 is located to pass
40 through the pivotal axis |44 for the lever |42,
so that either or both of the levers 98 and |34
may be adjusted to a neutral position in which
they move as a unit with the lever |42 about the
position for operation upon an 8C shoe, with the
pivot block |08 for the link |06 directly over the
pivot ||2 of the feed lever 60, the gear box |52
will be held in the position illustrated in Figs. 2
and 6, in which all portions of the track |50 are
equi-distant from the pivot |38 forming the rear
connection for the link |46, so that no forward
or back movements will be imparted to the lever
|42 and roller 90 by the movement of the slide |48
in its track.
The connections to the sun and planet gear
mechanism from the angular pattern cam |30
on the pattern cam shaft 58 of the machine com
prise a cam lever |68 supported on a vertically
extending pivot shaft |10 and provided with a
roller |12 arranged for engagement against the
cam |30. The cam lever |68 is connected by
means of a link |14 to a lever arm |15 carried
on a rock shaft |18 which also has supported
thereon a lever arm |80 connected by a forwardlg
extending link |82 to a gear segment lever |84
supported on the pivot |56 for the gear box |52.
The movements imparted to the gear segment
lever |84 from the angular cam |30 and the turn
ing movements imparted to the casing |52 from
the feed lever 60, together control the operation
of the sun and planet mechanism hereinafter
described to impart predetermined movements to
the slide |48 along the track |50. These move 30
ments of the slide |48 in combination with the
angular movements of the gear box | 52 and track
|50 supported thereon, operate to determine the
direction and amount of the forward and back
35
movements imparted to the templet roller 90.
The sun and planet mechanism through which
movements are imparted to the slide |48 com
prises >a vertically extending shaft |86 rotatably
supported in the gear box |52 having secured
thereto a gear |88 and to the bottom end there
of a pinion |90 which engages with a rack |92
pivotal axis |44, and are thus rendered inopera
rigidly secured to the machine frame and formed
45 tive to vary the forward and back movements im
in the shape of an arc with the pivot |54, |56 of
the gear box |52 as a center. Loosely mounted
on the shaft |86 above the gear |88 is a large
gear |94 which meshes with a gear segment |96
formed on the gear segment lever |84. Mounted
on the under side of the large gear |94 are three
planet gears |98 which are arranged to mesh
with the gear |88 above referred to, and also with
an internal gear 200 formed on a member 202
which is loosely mounted to turn on the shaft
|86, and is provided with a gear segment 204
parted to the arm 92 and templet roller 90 by the
actuation of the U-shaped lever |42.
In-and-out movements are imparted to the
templet roller 90 and its slide support 92 from
the length size control device, through connec
tions including a link |46 which is connected at
its rear end to one of the pivot pins |38, and op
erates to swing the U-shaped lever |42 about its
pivot. At its forward end, the link` |46 is con
nected to a slide member |48 (see Figs. 3, 6 and
7) supported to move in a track |50 formed in a
gear box member |52 which is supported on sta
tionary pivots |54 and |55 on the machine frame
and forms part of the sun and planet gear
mechanism referred to. The track |50 passes
through the axis of the pivots |54, |56, and fol
lows an arcuate path having the link |46 for its
radius.
The angular position of the gear box |52 is di
rectly controlled from the feed lever 60 through
the size adjusting mechanism above described
including the pivot block | 08 and link |06 through
connections which comprise a crescent-shaped
lever |58 (see Fig. 3) which is supported on a
stationary pivot |66 and at one end is connected
by a short link |62 to the pivotal connection be
tween the link |06 and the rear end of the con
trol lever 94 (Fig. l1) and at its other end is
connected by a forwardly extending link |64 to
75 Athe right-hand side of the gear box member |52.
which meshes with a rack 206 on the slide mem- _
ber |48.
With this construction and arrangement of the
sun and planet mechanism, rotational move
to the member 202 to
move the slide member |48 in the track |50 by
turning the gear box |52 on its pivot |54, |56 GO
which operates by the engagement of the pinion
|90 with the stationary rack |92 to rotate the
gear |88 and planet gears |98 meshing there
with, which in turn operate through their en
gagement with the internal gear 200 to rotate the
member 202. Movement is imparted to the rack
|48 also from the angular cam |30 which operates
through the gear segment lever |84 and segment
|96 to rotate the large gear |94, thus causing the
planet gears to be moved bodily around the
gear |88, and thereby through the engagement
of the planet gears with the internal gear 200
rotating the member 202 to move the slide |48 in
one direction or the other on its track |50.
Thus, the rocking of the gear box |52 around its
pivot |54, |56, under the influence of the con
nections including the crescent-shaped lever |58
and link |06 from the feed> lever 60, operates to
swing the track |50 away from its position nor
mal to the pivotal connection. |38 for the link
|l|6`,-and at' the same time through the operation
of ‘the sun and planet mechanism above de
scribed, serves to impart lengthwise movement to
the slidel Hi8 in the track |501, and thereby to
rock the lever |42 about its pivot to move the
the stations or points of contact 220` of the tem
plet roller 90 with the contour outline 2|,4 of the
templet 36 may be determined for each length
size of shoe being operated upon bythe position
of the trimming cutter on the corresponding con
struction line 226. Applicant’s length size grad
ing device above described is arranged to impart
forward and back movements and lengthwise
movements in the line of feed to the roller` 90
which are arranged to cause the roller for each
of the operating stations above described to be
templet roller 90 in or out, as the case may be.
This movement of the slide |28 is modined as
located on a line which is `parallel to the corre
above described by the operation of the angular
through the circle 22,0, and thus to secure the
proper relative positions of the cutter and roller
cam |30 and its connections including the gear
segment lever |84 forming part of the sun and
sponding construction line 226, and passing
illustrated by the diagram. The length and di
rection of movement of the roller 80 along this
planet gear mechanism.
The principle of operation of connections from imaginary path from the normal position indi
the feed lever 60 and angular cam |30 including 'cated by the corresponding circle 220 is deter
mined for each operating station directly by
20 the sun and planet mechanism above described to
effect the desired in-and-out adjustments in ac
cordance with the length size of shoe being op
erated upon during the transfer of thepoint of
operation about the shoe, will be readily under
25 stood in connection with the explanatory diagram
Fig. 19 of the drawings. As shown in this ñgure,
all the adjustments are made from a single ref
erence point 2 |0 at the toe of the shoe, which is
always located at the same point with relation to
'30 the master templet regardless of variations in
length or width of shoe being operated upon. In
the diagram referred to, the line 2|2_represents
the contour path followed by the trimming cut
ter around the sole margin oí a size 8C shoe.
The line 2M represents the outline of the master
templet, which is designed to correspond exactly
to the margin contour of a size 8C shoe, so lthat
vthe templet roller 90, when maintained in a
stationary position, will operate by engagement
with the templet during the transfer of the
`point of operation about the shoe, to cause the
trimming cutter to follow exactly the desired
contour path required for the trimming of an
8C shoe. The dotted outline 2|6 represents the
margin contour of a size 11C shoe in the position
which it will occupy with relation to the templet
contour 2|4 when supported on the jack. Simi
larly, the dotted line 2|8 represents the margin
contour of a 5C shoe when supported in operating
position on the jack. The circles 220 on the tem
plet contour 2M represent a series of points of
contact of the templet roller 90 .against the tem
plet during the transfer of the point of operation
about an 8C shoe.
The circles 222 on the contour
line 2| 2 of an .8C shoe, represent corresponding
`positions of the trimming -cutter 28 `against the
shoe, as shown by construction lines 224 connect
ing corresponding `circles on the contour lines
2|2 and v2|¢|. In order to ascertain the proper
relative position of the trimmingcutter 28 and
the templet roller 90 foreach of the stations il
lustrated by the circle 220 during the operation
about a relatively larger or smaller shoe, a num
ber of construction lines 226 have been drawn
radiating from the reference .point 2 l0, and pass
ing through each of the circles 222. The point
of intersection of each construction line 226 with
the contour path 2|6 for an 11C shoe, is `marked
by a circle 228, and similarly, the point- of inter
section of each construction line 226 with the
‘ margin contour line 2 I8 for a 5C shoe, is marked
by .a circle 230.
It will readily be seen from an inspection of
" 75
Fig. “19,that the relative position of the trimming
cutter 28 andthe templet roller f90 for each of
the position of the feed lever 60 and link |06 ~
in accordance with the setting of the pivot block
|06 for the length of shoe being operated upon.
At the starting position for operation upon a
shoe, the roller 00 will be located at the maximum
distance away from the normal position indicated
by the circle 220, and gradually approaches the
normal position indicated by each successive cir
cle 220 due to the continued movement of the
feed lever 60 until the toe is reached when the
roller 00 is brought exactly to its normal position,
.as indicated by the corresponding circle or refer
ence point 2 l 6. During the subsequent operation
on the opposite side of the shoe, the roller is
again moved away from its normal position byï.
an amount which is proportional to the move
ment of the feed lever, increasing gradually to a
maximum at the end of an operation on the
opposite side of the shank portion of the shoe.
It is the function of the sun and planet mecha A0
nism controlled by the angular cam |30 and by
the connections from the feed lever 60 to adjust
the forward and back position of the roller 90 as
the point .of operation is transferred about the
shoe to cause the roller 90 4at all >times to travel
along this imaginary path parallel to the con
struction line 226 corresponding to each succes
sive station 220 in the transfer of the point of
operation about the shoe.
The relative `starting positions of the templetf; ,150
roller 00 and the cutter 28 for operation upon an
||C shoe are shown in Figs. 3 and 18. The `ad
justing slid-e block lill vand pivot block |08 have
been adjusted to their extreme rear position, so
that a maximum throw is imparted to the roller`
00 by any movement of the feed lever 60. As the
shoe supported on Áthe jack is now brought >into
operating position, it will be seen that the feed
lever 60 is` moved to its extreme position to the
right, thus causing the roller 90 also to `be moved s60
to the right aproportional amount. This move
ment of `thefeed lever 60 at the same time acts
through the link |06, crescent-shaped lever |58
and link |64 to swing thegear box |52 and track
|50 about the pivot |54, |56. The movement of 65
the gear box in turn is rendered operative
through the operation of the sun and planet
mechanism above described, as modified by the
starting position of the angular ca_m |30, to move
the slide |48, retracting the roller V90 a `slight
amount so that the roller is` maintained on a line
passing through the starting station 220 and
parallel to the construction line 226. As the
point of operation progresses toward the toe of
the shoe, the movement of the feed lever causes 75
6
2,127,707
the roller 90 to be gradually moved to the left
until at the toe it is directly in line with the
cutter 2B. The continued movement of the feed
lever to the left as the point of operation is
transferred along the other side of the shoe,
causes the feed roller 90 also to continue its move
ment to the left by an amount Which is propor
tionally increased as the point of operation again
approaches the shank portion of the shoe. The
10 in-and-cut movements of the roller 90 are con
trolled by the movement of the feed lever 60 and
by the rotation of the angular cam |30 acting
through the sun and planet mechanism as above
set forth, to cause the resulting movement of the
15 roller 90 from the normal position for each suc
cessive station represented by the circles 220, to
take place along a line parallel to the correspond
ing construction line 226, so that the relative po
sitions of the roller 90 and cutter 28 at each of
20 the operating stations about the shoe will be ac
curately represented by the relative positions of
25
the circles 220 and 228. The actual path of move
ment of roller 90 about an 11C shoe is indicated
by a dot-and-dash line 232 in Fig. 18.
The relative starting position of the templet
roller 90 and the cutter 28 for operation upon an
8C shoe is shown in Figs. 2 and 1'7. The ad
justing slide block ||4 has been moved to its
middle or size 8 position, in which the pivot block
30 |08 is directly over the pivot ||2 of the feed
lever 60, so that no movement is imparted to the

There is also provided in the present construc- '
tion a width size grading mechanism which op
erates in combination With the length size grad
ing mechanism above described to cause the
trimming cutter 28 to follow any one of a number
of predetermined contour paths which extend
over the entire range of widths of shoe for each
length, as determined by the setting of the
length size adjusting slide block ||4. The width
size control mechanism comprises mechanism
for imparting additional in-and-out movements 30
to the templet roller 90 which are additive to

The relative starting position of the templet
roller 90 and the cutter 28 for operation upon a
5C shoe is shown in Fig. 16, in which the adjust
ing slide block I |4 and pivot block |08 have been
adjusted to their extreme forward position on
45 the feed lever 60, so that as the shoe supported
on the jack is brought to starting position and
the feed lever 60 is moved to the right, the swing
lever 94 is moved in a clockwise direction from
the position shown in Fig. 2, causing the templet
50 roller 90 to be moved a proportional distance to
the left. This movement of the feed lever 60 at
the same time acts through the link |06, cres
cent-shaped lever |58 and link |64 to swing the
55
movement to the right by an amount which is
proportionally increased as the point of opera
tion again approaches the shank portion of the
shoe. The in-and-out movements of the roller
90 are controlled by the movement of the feed
lever 60 and by the rotation of the angular cam
|30 acting through the sun and planet mecha
nism as above set forth, to cause the resulting
movement of the roller 90 from the normal po
sition for each successive station represented by
the circles 220 to take place along a line parallel
with the corresponding construction line 226, so
that the relative positions of the roller 90 and
cutter 28 at each of the operating stations about
the shoe will be accurately represented by the
relative positions of the circles 220 and 230. The
actual path of movement of the roller 90 about a

direction about its pivot |54, |56. The movement
of the gear box in turn is rendered operative»
through the operation of the sun and planet
mechanism above described, as modiñed by the
60 starting position of the angular cam. |30, to move
the slide |48, advancing the roller 90 a slight
amount. This relative starting position is illus
trated in diagrammatic form in Fig. 19, by the
relative positions of the circle 230 representing
65 the starting position of the cutter, and the cor
responding circle 220 representing the starting
position of the templet roller 00. As the point
of operation progresses toward the toe of the
shoe, the movement of the feed lever to the left
causes the roller 90 to be gradually moved to the
right until at the toe it is directly in line with
the cutter 28. Continued movement of the feed
lever to the left, as the point of operation is
transferred along the other side of the shoe,
75 causes the feed roller 90 always to continue its
The forwardly extending arm of the cam lever
242 is connected by a link 244 to a lever arm 246

tends through the pivotal axis of the shaft 248.
An adjustable slide block 252 (see Figs. 14 and
l5) supported in the track 250 is connected by a
link 254- to one arm of a lever 256 supported on a 45
vertical pivot 258, and connected at its other end
to a rearwardly extending link 260.
At its rear
end, the link 260 is connected to the U-shap-ed
lever |34 at a point which passes through the
axis of rotation of the length size adjusting lever 50
|42. With this construction and arrangement of
the width control mechanism, it will readily be
seen that when the slide block 252 is located ex
actly on the pivotal axis of the lever 246, no
movement is imparted to the connections includ 55
ing the lever 256. link 280 and width size control
lever |34. For this adjustment of the parts, the
pivotal connection between the link 260 and the
lever |34 is located in axial alignment with the
pivot _|44 of the lever |42, so that the lever |34 60
swings as a unit with the length size control lever
|42. When the pivot block 252 is adjusted to the
right from the position shown in Fig. 3, move
ment is imparted to the connections above de
scribed including the Width size control lever |34 65
to move the templet roller 9F! forwardly a propor

block 252 for the narrower size shoes. Similarly,
an adjustment of the width size control pivot

In accordance with one feature of the invention,
an adjustment is provided in the mechanism for
controlling the position of the templet roller 9|]
to determine the width of the margin about the
shoe sole left by the edge trimming operation in
, dependently of the length, width or style of shoe

upon, it is necessary only to utilize a different
master templet which will extend the range of
adjustment to either larger or smaller size shoes; .20
to the lever 256 by means of a nut 216 which is
mounted on a threaded portion of the link 266,
and is pivotally supported by pins 211 in the
forked end of the lever 256, so that rotational
25 movement of the link 26|] will operate either to
lengthen or shorten the link connection between
as may be desired. For operation upon «widely
different styles of shoes, a different set of»v pat
tern cams may be necessary to impart the correct
tipping and turning movements to the shoe dur
ing the transfer of the point of operation about,125

order to permit the free rotation of the link, the
rear end thereof is screw-threaded into a nut 218

|34. A manual control knob 219- secured to the
. forward end of the link 269 provides convenient
means for adjustment of the angular position of
the linkl268. It will readily be seen from an in
spection of Figs. 3 and 12 of the drawings, that
the adjustment thus provided serves to control the
angular position of the U-shaped width control
lever |34, and thus serves to provide an in-and

Further in accordance with the present inven
tion, the machine herein disclosed is provided
with means for varying the contour path followed
by the trimming cutter in order to provide for
variations in the style of shoe operated upon
without the necessity of employing a different
master templet. To this end a character cam 28|)
is supported on a supplemental shaft 282 which is
driven in synchronism with the pattern shaft 58
through connections which include a pinion 284

of applicants’ machine is constructed and ar
ranged to have mounted thereon a number of
sets of pattern cams which are vertically ad
justable to permit the substitution of one seit 30
for another in operatingv relationship to the
follower connections for actuating the jack. In
asrnuch as the mechanism for achieving this
adjustment is well-known in the art, and is fully
illustrated and described in the patent to Alfred; 35
