perform certain operations progressively along
operation of locating and locking the shoe on
the jack at the same time to locate the templet
the bottom margin of a shoe, and is hereinafter
surely and accurately with relation to the shoe,
disclosed as embodied in an edge trimming ma
so that the point of operation during the subse- 5
quent operation of the machine will follow a
predetermined outline about the shoe.
chine of the type in which the shoe and the edge
trimming devices are moved relatively to trans
fer the point of operation about the shoe, and
in which mechanism is provided for relatively
10 moving the edge trimming devices and the shoe
to maintain the edge trimming devices and the
shoe in proper relative positions at the point of
operation as said point is transferred about the
shoe. While the invention is intended primarily
15 as an improvement in automatic sole edge trim
ming machines, certain features of the inven
tion are capable of use in automatic machines
for performing operations other than edge trim
ming progressively along the bottom margin of
a'shoe. Certain features of the invention also
are capable of use in shoe machines which are
not automatic, and more particularly in non
automatic edge trimming machines.
It is a principal object of the present invention
25 to provide a templet constructed and supported
with relation to the shoe in a novel and improved
manner for causing the shoe operating devices to
follow a predetermined contour line during the
transfer of the operation about the shoe, and to
30 enable this operation to be performed in an accu
rate and reliable manner. to secure satisfactory
and uniform results without the use of skilled
labor, and notwithstanding irregularities in the
shoe contours- or variations and imperfections in
35 the shape or arrangement of the various parts
of the shoe produced during preceding shoe
making operations.
It is a further object of the invention to pro
vide in an automatic machine of the general type
40 which includes shoe operating devices and a shoe
supporting jack relatively movable to transfer
said devices along the bottom margin of a shoe
supported on the jack, a novel and improved
templet associated with the jack for determin~
45 ing the path followed by’ the point of operation
about the shoe constructed and arranged to per
mit the operation of ‘such devices both on the sole
edge and upon the adjacent bottom portion of
the shoe sole free from interference with the
50 templet or its supporting structure.
It is a further object of the invention to pro
vide a novel and improved assembly of a shoe

adapted to enable the operator by the simple
It is a further object of the invention to pro
vide, in a machine of the general type which com
prises shoe operating devices and a shoe sup- 10
porting jack, a templet having guiding surfaces
determined in accordance with the size and style
of shoe being operated upon for causing the shoe
operating devices during the transfer of the oper
ation about the shoe sole to follow a smooth and 15
regular outline irrespective of the irregularities
in the contour of the shoe, in which the guiding
surfaces of the templet are readily adjustable to
cause the path followed by the operating devices
to conform generally to different widths of shoes. 20
With these and other objects in View as may
hereinafter appear, a principal object of the
invention consists in the provision of a templet
comprising two rigid arms pivotally supported
adjacent the toe portion of the shoe supporting
jack and arranged for engagement with side
portions of the shoe upper to secure an auto
matic adjustment of the contour lines of the
templet in accordance with the width of shoe
being operated upon.
'
30
Another feature of the invention consists in
the provision of a clamping device for securing
the free ends of the templet arms against the
side portions of the shoe irrespective of the posi
tion of the shoe on the jack to insure the cor
rect location of the templet guiding surfaces with
relation to the shoe sole.
The several features of the present invention
consist also in the devices, combinations and ar
rangement of parts hereinafter described and
claimed, which together with the advantages to
be obtained thereby will be readily understood by
one skilled in the art from the following descrip
tion taken in connection with the accompanying
drawings, in which Fig. 1 is a View in front ele 45

The automatic shoe edge trimming machine
10 herein disclosed as embodying in a preferred form
the several features of the invention, comprises
a machine head 20 which has supported therein
an electric motor provided with a vertically situ
ated armature shaft 22 which carries at its lower
15 end a rotary edge trimming cutter 24.
The ma
chine head 29 is bolted to a base 26 which pro
vides a support for the driving and stopping
mechanism generally indicated at 23, and serves
as a housing for the jack supporting and actuat
20 ing mechanisms.
The shoe supporting jack herein disclosed is
substantially that illustrated and described in
the application of Garrett P. S. Cross, Serial No.
584,325, filed January 2, 1932. The jack, as best
25 shown in Figs.~3 and 5, comprises a vertically ar~
ranged spindle 35 having rigidly formed‘ on its
upper end a frame 32 which carries the toe sup
port 34. Cooperating with the frame 32 is an
arm 36 which is loosely mounted on a pivot stud
30 38 to swing toward and away from the toe rest,
and carries at itsupper ‘end a heel supporting lever
40 and a vertically situated last pin 42 formed in
tegrally with the lever, which are arranged for
tilting movements toward and ‘away from the toe
35 rest about a pivot stud 44 on the arm 36. A spring
operative by the tripping of the feeler 58 to ar
rest further movement of the arm 36 toward the
toe rest. The mechanism for locking the parts
of the jack in the position illustrated in Fig. 5,
comprises a locking rack bar ‘i2 pivotally secured
at one end to the lever arm 52, and at its other end
provided with a’ rack arranged for engagement
with a pinion ‘i4 mounted'on a rotatable shaft
16 on the jack frame 32. There is also secured
to the shaft 76, a ratchet T! which is arranged 10
for engagement with a locking detent 18 when
rendered operative by the engagement of a shoe
toe with the feeler 58.
Inasmuch as the con
struction and mode of operation of the stopping
and locking devices thus far described, together
with the mechanisms for controlling the opera
tion of the stopping and locking detents if) and
"[8 respectively from the feeler member 58, are
fully illustrated and described in the Cross ap
plication above referred to, and form speci?cally
no part of the present invention, a further de
scription of these mechanisms is believed un
necessary.
The jack illustrated is also provided with toe
clamping devices for locating and rigidly clamp
ing the toe portion of the shoe in adjusted posi- ‘
tion laterally of the jack. These devices, as il
lustrated in Figs. 3 and 5, and as more fully de
scribed and illustrated in the Cross application
above referred to, comprise two toe clamps 80
and 82 which are carried respectively on two
carrier arms 84 and 86, and are arranged for
engagement with opposite sides ofthe shoe up
per adjacent the toe of a shoe‘ supported on the
jack. Each of the carrier arms 34 and 3G is
45 coiled about a pivotjstud 48 on the frame 32
shaped to extend downwardly and horizontally,
connected at one end to a pin 50 von the swinging
arm 36, and at its other end anchored in a central
so that they‘ are located parallel and in close
proximity to each other under the toe rest 34.
The carrier arms 84 and 86 and toe clamps 8-3 and
82 carried respectively thereon, are mounted to 40
move toward and away from each other substan
tially in planes inclined downwardly toward the
center line of the jack, the carrier arm 86 be
ing pivotally secured at 88 to an upwardly ex
tending H-shaped lever 90 pivoted at 92 on the
jack frame, and the carrier arm 84 being sup
ported at 94 on alink 96 which is arranged to
bore in the spindle 30, tends normally to maintain
40 the arm 35 in a relatively retracted position away
from the toe rest 34. The tilting movements of
the heel supporting’ lever 4!! and heel post 42 are
controlled through mechanism which includes a
lever arm 52 pivoted at 54 on the arm 36, and
45 having formed on the hub thereof a gear segment
which meshes with a corresponding gear seg
ment formed in a downward cxtensionof the heel
supporting lever 46. A small tension spring 56
turn on a ?xed pivot 98 'on ‘the jack frame. . In
connected at one end to ‘a ‘pinch the arm 36 and
50 at its other end to the lever 52, tendsnor'mally to
order to control the position of the carrier arms
84 and 86, and also to provide an additional sup~
port therefor, the carrier arm 85 is provided with
tilt the heel supporting lever 40 and heel post 42
in a counterclockwise ‘direction as shown in Fig.
5, away’ from the toe rest.
In order to locate ‘a shoe on ‘the jack, the shoe
55 supported on 'a last ‘is ?rst ?tted onto the heel
post 42, and is then forced forwardly and down
wardly by the operator to bring the 'shoe toe into
engagement with the toe support 34 where it is
locked in position by the operation of stopping
and locking devices which are tripped into opera~
tion by the engagement of the shoe toe with a
feeler 58, and act respectively to prevent further
movement of the arm 36 toward the toe rest, and
at the same time to lock the arm 36, and heel
65
supporting lever ‘40 and post 42, against move
ment in a reverse direction under the pressure
' ofjtheir respective'springs, so that the shoe is
locked in position on the jack. The stopping
mechanism referred to, comprises a rack bar 62
70 pivotally secured at one end to the arm 36, and at
its other end _'provided with rack teeth engaging
with a pinion 64 on a rotatable shaft 66 on the
' jack
_> frame 32.
75
There is' also mounted on the
shaft 65 a stop ratchet 68 which is arranged to be
engaged by a stopping detent ‘H3 when rendered
a downwardly extending portion I510 journalled to
receive a pivot pin I02 in one arm of a bell-crank
lever I04 pivoted at I05 on the jacl; frame. The
two ends of the pivot pin Hi2 are ?attened to en- .
gage with slots formed respectively in the down
ward extending arms of the H-shaped carrier
lever 96, so that a movement of the bell-crank
I04 about its pivot, acts to move the carrier arm
84 and 'toe’clamp'?il inwardly or outwardly as the
case may be, and acts simultaneously by rocking
the carrier lever 9i) about its pivot 92 to impart
corresponding inward or outward movements to
the carrier arm 86 and toe clamp 82. The car
rier arm 85 ismaintained in proper angular posi 65
tion during relative movements of the carrier
arms and toe clamps above described, by means
of a boss I08 which projects laterally from the
carrier arm 84 and engages with a guideway H0
formed in the horizontal extension of the car 70
rier arm 86.
After a shoe has been located upon and locked
in position on the jack as above set forth, the
toe clamps'are moved into clamping engagement
with the toe portion of the shoe upper, to locate 75
2,115,978.
the toe laterally of the jack, andan additional:
rotative movement is imparted to the locking,
ratchet ‘I4 and associated parts to tighten the‘
jack by forcing the shoe toe downwardly into ?rm
engaging contact with the toe rest 34 by the op‘
erator, through the manipulation of a manually
operable clamping lever II2 which is loosely
mounted to turn on the pivot stud 48 on the
jack frame 32. Connected to the clamping lever
10 I I2 is a link II4 which is secured at its upper
end to an intermediate point on a cross lever II6
which operates when moved downwardly by the
actuation of the clamping lever “2 through
mechanism connected to one end thereof, to
move the toe clamps 80 and 82 into clamping
engagement with the shoe toe, and through mech
‘ anism connected to the other end thereof, to
3
ing:lever:II2 now causes the cross lever II6 to
turn about ‘its pivotal connection with the lever
I201as a fulcrum, to move the pawl I28 and
pawl lever‘ I30 against the pressure of the spring
I32 into ‘engagement with the locking ratchet
11,180 that an additional movement is imparted
thereto to draw, the locking rack ‘I2 toward the
toe' portion of the jack, to secure the desired
tightening effect.
The devices for supporting the jack and for 10
imparting thereto the required feeding, turning
and tipping movements to feed and to position
the shoe with relation to the shoe operating de
vices to transfer the point of operation about the
shoe, ;are substantially those well known in the 15
art, as illustrated, for instance, in the patent to
Alfred. R.-:Morrill, No. 1,952,770, dated March
impart an additional movement torthe locking
ratchet ‘I4 and associated parts, to tighten the
jack. One end of the cross lever H6 is pivotally
connected at H8 to a U-shaped lever I20 which
27, 1934, but may be brie?y described as follows:
The jack supporting mechanism as generally il
is supported to turn on two studs I22 on the
means of 'universal connections to turn with a
jack frame 32, and is connected through a link
224 to a horizontally extending arm of the bell
crank lever I04 for controlling the operative
positions of the toe clamps 80 and 82. The other
forwardly extending jack supporting arm I42.
The supporting lever I42 is pivotally supported 25
end of the cross lever H6 is connected through
a, link I26 to the tail portion of a pawl I28 which
is pivoted on a pawl lever I30 mounted to turn
30 freely on the supporting shaft ‘I4 for the ratchet
‘I6. A tension spring I32 connected between an
extension on the pawl lever I30 and a pin I34
on the jack frame 32, tends normally‘ to main
tain the lever I30 and pawl I28 in a fully raised
35 or retracted position. A tension spring I36 se-'
cured at one end to‘the manual clamping lever
H2 at the point of connection with the link II 4,
and at its other end on a pin on the jack frame;
tends to swing the lever in a counterclockwise
direction as shown in Fig. 5, to a normally re
tracted rest position.

The operation of the manually operable clamp
ing lever II2 ?rst to move the toe ‘clampsi80
and 82 into clamping position, and thereafter
' to impart an additional movement to the ratchet
‘I4 to tighten the jack, may be described as fol-'
lows:-
I

'
Assuming that a lasted shoe has been'placed
on the last pin 42, and the shoe then moved
forward to engage the shoe toe with the toe‘ rest
34 and feeler 58 so that the stopping and lock‘
ing detents ‘I0 and ‘I8 are rendered operative
to lock the shoe in the jack, the operator now
moves the manual clamp lever II 2 sharply up
ward in a clockwise direction as shown in Fig. 5,
causing the link II4 and intermediate portion of
the cross lever I I6 connected thereto to be moved
downwardly. Since a considerable resistance
is provided to the movement of ‘the left hand
60 end of the cross lever II 6 and pawl mechanism
above described, by the spring I32, the cross
lever I i6 will turn about its pivotal connection
with the link I26 to swing the U-shaped lever
!28 downwardly, and, acting through the link
I24 and bell-crank I04, will move the‘toe clamps
80 and 82 into clamping engagement with the
side toe portions of the shoe upper, so that the
shoe is ?rmly held in an adjusted position lat
erally of the jack. The toe clamps are positively
70 locked against movement relatively away from
each other by means of a locking device not here
shown, which is identical with that illustrated
and described in the Cross application above re
ferred to.
I
The continued turning of the manual clamp
lustrated‘in Figs. 1, 2, and 5, comprises the jack
spindle>30 which is connected at its lower end by
pulley I48 which is supported on the end of a
for vertical swinging movements on a lever I44
which-is carried on a vertical pivot post on the
upper end of a frame I46 which is in turn piv
oted‘for swinging movements forward and back
on twoipivot studs I48 supported on the base 30
26. The frame I46 is moved forwardly and back
to>-.provide the necessary roll tipping movements
toth‘e- jack and shoe supported thereon about the
point of. operation, by means of connections com
prisinga lever arm I50 which is rigidly secured
to a sleeve hub I52 on a vertically extending
pivot post I54, and at its free end is connected
by a short link to the frame M6. There is also
rigidly secured to the sleeve hub I52, a cam le
ver I56 which carries a cam roll I58 arranged 40
for engagement with the roll cam I60 on the
pattern cam shaft I62 of the machine. Lateral
swinging movements are imparted to the lever
I44 to‘impart the required longitudinal or pitch
tipping movements to the jack and shoe sup 45
ported thereon about the point of operation,
thrbugh connections which comprise an arm I64
rigidly secured to a downwardly extending tail
of the ‘lever ‘I44, and connected through a link
I66 to a lever arm I68 which is rigidly secured 50
to. a sleeve hub I‘I0 on the vertical pivot post I54.
Secured to‘the sleeve hub H0 is a cam lever I72
which carries a cam roll I14 arranged for en
gagement'with a‘ pitch cam I16 on the pattern
cam shaft I62. Rotational or turning move 55
ments are imparted to the jack through connec—'
tions including a‘ cord or cable I78 which passes
around the pulley I40 and an idler pulley I85
on the rear end of the arm I 42, and is secured
to a‘pulley I82 supported on a vertical pivot E84 60
on'the base 26. A pinion I86 formed on a sleeve
hub of‘ the pulley I82 is arranged to mesh with
a-corr'esponding gear segment formed on a lever
I88 sleeved ,on the vertical pivot shaft 554. There
is also "secured to the sleeve hub of the lever I88,
a‘camrlever I90 which carries a cam roll I 92
arranged for‘ engagement with a turn cam I94
on thepattern cam shaft I62. The required feed
ing‘ movements are imparted to the jack to trans
fer the ‘point of operation along the margin of
the shoe sole, by means of a feed lever I96 which
is supported at its rear end on a vertical stud
I98 on ‘the base 26,‘and at its forward end is
connected by means of a feed link 280 to the
toe portion of the jack. The feed lever is con
4
2,115,978
nected through links 202 and 284 to one arm of
a cam feed lever 206 which is supported on a
pivot stud 268, and has mounted on the other
arm thereof a cam roll 2“) arranged for en
Ci gagement with the feed cam 212 on the pattern
cam shaft I62. The jack is further supported to
maintain the jack and shoe supported thereon
in cooperative relationship to the shoe guiding
and operating devices, by means of a link 2l4
10 which is pivotally connected at its rear end to a
bracket 216, and at its forward end is connected
by means of a universal joint to the upper por
tion of the jack spindle 30. Inasmuch as the
details of the construction and mode of operation
15 of these mechanisms to impart the required
feeding, turning and tipping movements to the
jack, are well known in the art, no further de
scription thereof is believed necessary.
In accordance with the present invention, novel
20 and improved guiding means are provided com
prising a templet and templet guide for guiding
the shoe with relation to the operating devices
as the point of operation is transferred about
the shoe, to cause the operating devices to fol
25 low a predetermined outline around the margin
of a shoe.
To this end, a templet of novel and
improved design is provided associated with the
jack and shoe mounted thereon, which is ar
ranged for engagement with a relatively station
30 ary templet guide mounted on the Work head 20
to engage with the templet at a point closely
adjacent the point of operation of the shoe‘ op
erating devices. As best shown in Fig. 30f the
drawings, the templet guide comprises a verti
35 cally extending plate 220 which provides a point
of contact with the templet directly beneath and
somewhat to the rear of the point of operation
of the shoe operating devices, and is curved lat
erally away from each side of a central vertical
40 line to maintain the correct operating relation
ship between the operating devices and the mar
gin of the shoe sole during the turning move‘
ments of the jack. The templet guide or plate
226 is formed on the forward end of a slide sup
port 222, mounted for sliding adjustment in a
groove 224 formed in the under side of a support
226 which carries the usual crease guide 228,
being adjustably secured thereto by means ‘of a
clamping screw 236 which extends through a
slot 232 formed in the support 222. The crease
guide support 226 is in turn supported for a for
ward and back adjustment on two downwardly
extending lugs 234 and 236 formed on the under
side of a bracket 238 secured to the machine head
20. The support 226 is slotted at its rear end
'to receive a clamping bolt 239 screw-threaded
into the lug 236, and at its forward end is ar
ranged for sliding engagement in a guideway
formed by two downwardly extending arms of
60 the lug 234. A slight vertical adjustment of the
crease guide 228 is obtained by means of a pin
24!] which is provided with an eccentric mid
dle portion ?tted into a transverse bore in the
slide 226, and has its ends engaging with ‘slots
roll cams above described, are formed with re
lation to the guiding surface of the templet so
that the shoe will be correctly positioned with
relation to the edge trimming cutter at all times
during the progress of the operation about the
shoe to trim the sole edge cleanly and accurately
to the desired shape.
As best shown in Figs. 3, 4, 5, and 6 of the
drawings, the templet comprises two ?at plates
246 and 248 which are located respectively along 10
each side of the shoe, and have their outer edges
shaped to provide a contour surface correspond
ing substantially to the outline to be followed by
the operating devices during the operation around
the shoe. ‘Adjacent the toe portion of the shoe, 15
the plates 246 and 248 are arranged to over
lap, and are pivotally supported on the jack by
means of a pivot stud 250 mounted in a bracket
252 secured to the frame 32.
In accordance with one feature of the present 20
invention, the templet plates 246 and 246 are
arranged at their heel ends for clamping en
gagement with the shoe upper, so that the tem
plet is located in a predetermined relationship
to the shoe independently of any variations 25
which may exist in the location of the last pin
socket in the last, and also in a position which
will correspond exactly to the width of shoe be
ing operated upon. The templet plates 246 and
248 are supported vertically with relation to the 30
shoe and are clamped to the shoe upper ad
jacent the heel by'means of two clamping levers
254 and 256 which are pivotally supported at
each end of a cross arm 258 formed integrally
with the heel supporting lever 40, and are ar 85
ranged for supporting engagement respectively
with the under sides of the templet plates 246
and 248, and for clamping engagement with two
clamping plates 26!! and 262 secured respectively
to the templet plates 246 and 248. The clamp 40
ing plates 260 and 262 are each provided with
vertically disposed surfaces for engagement with
the shoe upper, and at their heel ends with out
wardly extending ?anges which are arranged,
during the opening of the jack, to engage with
the clamping levers 254 and 256 and limit the
movement of the heel supporting arm 36 and
last pin lever 46 away from the toe portion of
the jack. With this construction and arrange
ment of the parts, the clamping levers 254 and
256 are maintained atv all times in operative re
lationship to the templet arms and clamping
plates, so that after a new shoe has been placed
in the jack, it is necessary only to move the
clamping levers into clamping position to locate
the templet in adjusted position with relation
to'the shoe. The clamping levers 254 and 256
are connected at their lower ends by means of
two toggle links 264 and 266, and are normally
moved relatively apart to maintain the clamp
ing' levers in an open retracted position by means
of a tension spring 268 connected across the
lower ‘ends of the clamping levers. In order to
bring the clamping levers 254 and 256 into

position on the jack, below the level of the ‘shoe
70 sole and out of contact therewith, to permit a
lever 210 is provided, pivoted at 212 on the heel
arm 36, and provided with a bearing surface 274

for withdrawing the detent 280 to permit the re
lease of the lever 2m and clamping levers 25d
15 and 256 when it is desired to remove the shoe
from the jack.
.
With the construction and arrangement of the
templet and jack associated therewith herein
illustrated and described, only a simple opera
20 tion is required to enable the operator quickly
and accurately to locate and clamp a shoe on
the jack and to secure the templet in adjusted
position with relation to the shoe. The locat
ing of the shoe longitudinally on the jack as
25 determined by the engagement of the shoe toe
with the feeler 58, serves also to locate the tem
plet, secured to the toe supporting frame 32,
longitudinally of the shoe sole. The subsequent
operation of moving the toe clamps into clamp
30 ing engagement with the toe portion of the lasted
upper in tightening the jack, serves to locate the
toe portion of the shoe laterally of the jack, and
also laterally with relation to the templet mount
ed on. the jack.
The two arms 246 and 248 of
35 the templet are thenbrought into clamping en
gagement with the heel portion of the, shoe up
per to secure the templet ?nally in adjusted po
sition with relation. to the shoe, by the opera
tion of the manual clamping lever 210 which
4:0
operates through the straightening of the toggle
links 284 and 266 to move the clamping levers
254 and 256 into tight clamping engagement
with the plates 26!! and 262 against the lasted
upper. It may be noted at this point that the
45 arrangement of the clamping levers 254 and 256
is such as to permit a free, adjustment in the
clamping position of thelevers laterally of the
jack, so that they will be brought into tight
clamping engagement with the shoe, causing
50 each of the templet plates 246 and 248 to be
held accurately in. position against the shoe up
per, irrespective of any possible variations in
the lateral positioning‘ of the shoe heel which
might result from inaccurate location of the
55 last pin socket in the last.
With the construction and mode of mounting
the templet with relation to the shoe herein dis
vantage that the templet is located entirely from
the lasted shoe upper, so that the outline fol
lowed by the shoe operating devices about the 1O
margin of the shoe, must correspond exactly to
the location of the lasted upper to insure a cor
rect proportion of all the parts of the ?nished
shoe. This is of particular importance in con
nection with the edge trimming operation for 15
which the present templet is particularly in
tended.
‘
.
‘
The location of the templet at a level con
siderably below and outside the sole of the in
verted shoe on the jack, has a speci?c advantage 20
in providing adequate space for the operation of
devices which act upon the margin of the shoe
sole, and also where desired, upon the bottom 01’
the shoe sole. This arrangement of the templet
makes possible the use of a templet in forming 25
a channel in the shoe sole, so that the templet
may be utilized, for instance, in connection with
machines which are constructed and arranged
for simultaneously performing an edge trimming
and channeling operation.
30
The several features of the present machine
and the advantages to- be obtained thereby hav
ing been pointed out, and a speci?c. embodiment
of the invention having been described, what is
claimed is:-—
‘

’ 1. A shoe machine having, in combination, de
vices for operating upon a lasted shoe, and a shoe
supporting jack relatively movable to transfer
said devices along the bottom margin of a lasted
shoe supported on the jack, a templet guide, and 40
a templet arranged for clamping engagement
with the shoe upper to locate the guiding surfaces
of the templet with relation to the shoe to deter
mine the outline on the shoe followed by the shoe
operating devices.
2. A shoe machine having, in combination, de
45
vices for operating upon a shoe, and a shoe sup
porting jack relatively movable to transfer said
devices along the bottom margin of a lasted shoe
supported on the jack, a templet guide, and a 50
templet mounted on the jack and arranged for
engagement with the shoe upper to locate the
guiding surfaces of the templet with relation to
the shoe to determine the outline on the shoe
followed by the shoe operating devices.
3. A shoe machine having, in combination, de
55
vices for operating upon a shoe, and a shoe sup
closed, the templet automaticallyadjusts itself
porting jack relatively movable to transfer said
to the width of shoe placed in the jack, so that
devices along the bottom margin of a lasted shoe
supported on the jack, a guide with relation to 60
which the jack moves during the operation on a
60 only one templet is required for all widths of any
given size and last of shoe. Inasmuch as the
templet plates 2% and 2188 are of rigid con-_
struction, the proportions and length of the out
line followed by the shoe operating devices along
65 each side of the shoe, are necessarily constant.
As the heel portions of the templet plates 246
and 248 are brought closer‘together for ‘opera
tion upon progressively narrower widths of shoe,
the outline followed by the operating devices
70 along each side of the shoe starting fromy the,
shoe toe, will follow a progressively narrower path
as the shank portion of a shoe is reached. This
variation in outline follows substantially the
change in shoe outline of progressively narrower
sizes, since in progressively narrower sizes, the
shoe, a templet movably mounted on the jack
and cooperating with the guide during the rela
tive movement of the jack and guide to deter
mine the outline on the shoe followed by the oper 65
ating devices, means for locating the templet on
the jack in operative position with relation to
the shoe, and means for separately supporting
the shoe and templet on the jack to permit the
independent removal of the shoe from the jack. 70
