MACHINE FOR APPLYING PRESSURE TO
SHOE BOTTOMS
Francis J. Better, Beverly, Mass, assignor to
United Shoe Machinery Corporation, Paterson,
N. J., a corporation of New Jersey
Application May 22, 1936, Serial No. 81,367
11 Claims.
This invention relates to improvements in ma
chines for use in applying pressure to- shoe bot
toms and is illustrated herein by way of example
as embodied in a machine for cement attaching
5 soles to shoes of the type disclosed in United
States Letters Patent No. 2,047,185, granted July
14, 1936 on an application ?led in the name of
Milton H. Ballard et al.
In most machines for cement attaching soles
10 to shoes the sole and shoe are mounted on a pad
and pressure is applied to the shoe bottom either
by in?ating the pad while the shoe is supported
against the pressure thereof or by pressing the
sole and shoe forcibly against the pad. Accord
ingly, means is usually provided for engaging the
shoe and the last in the shoe during the pressure
applying operation, this means in some cases
supporting the shoe against the pressure of the
pad and in other cases cooperating with pressure
20 applying mechanism to press thesole and shoe
against the pad.

When operating on. high shoes, that'is, shoes
having uppers which are open at the front and
lace up- over the wearer’s instep, it is often diffi—
cult to move the last-engaging means usually
employed in such machines into position to en
gage the last without bending or distorting the
portion of the upper which extends above the
top of the last so that there is danger of pinch
ing the upper between the last and the engaging
means during the pressing operation.
An object of the present invention is to provide
improved last-engaging means for supporting or
pressing a sole and shoe on a pad which will be
particularly adapted to operate on shoes having
uppers which extend beyond the tops of the lasts
in the shoes without distorting or interfering with
the extended portions of the uppers.
To this end and'in accordance with one fea
ture of the invention there is provided a last
engaging member or abutment arranged for
movement relatively to a high shoe located on a
supporting pad and means for moving the abut
ment into and out of position to engage the last
in the shoe without dislocating the portion of
the shoe upper-which extends beyond the top of
said last. As illustrated, the last-engaging abut
ment comprises a curved arm having a last-en
gaging surface which is‘ considerably. narrower
than the top of a last. Above the narrow por
tion of the abutment is a laterally extending
?ange which is wider than the top' of a last and
tapers at the rear portion of the abutment. ‘The
abutment is pivotally connected to pressure-ap
55 plying means which, in the illustrated construe
(c1. 12-7-33)
tion, comprises a lever carried by a swinging mem
ber and adapted to press the sole and shoe against
the pad to apply sole attaching pressure. As
illustrated in the patent referred to, the swing
ing member is arranged to move outwardly and
inwardly relatively to- the pad about an axis lo—_
cated below the pad. and a handle is provided for
swinging the member into operative position.
The means for moving the last-engaging abut
ment into position to engage the last during the 10
pressing operation without distorting or displac
ing the extended portion of the upper comprises,
as herein illustrated, a'pivoted lever adjacent to
the handle referred to and in position to be en
gaged, by the operator when he grasps the handle.
The pivoted lever has another arm connected by
intermediate mechanism to the last-engaging
abutment. By this construction after the oper
ator moves the swinging member into operative
position to locate the last-engaging abutment
over the pad, he can actuate the pivoted lever
to swing the abutment longitudinally of the pad
through the opening at the front of the upper
and into position to engage the top of the last
before the pressure-applying lever moves the
abutment against the last to apply the sole-at
taching pressure.
Since the ?ange on the abutment is tapered it
will enter the opening'at the front of the upper
and spread or separate the side portions of the 30
upper so that they will not'contact with the top
of the last, thereby permitting the narrow last
engaging surface of the abutment to engage the
last without danger of pinching the upper be
35
tween it and the last.
A spring is provided for automatically return
ing the abutment to inoperative position, the
spring being just strong enough to swing the
abutment into inoperative position when pres
sure on the shoe is relieved, thereby preventing 40
damage to the mechanism through the force of
the spring but causing the abutment to be re
turned to inoperative position while it is still
located over the shoe on the pad.
,
With the above and other objects and features
in View the invention will now be described in
45
detail in connection with. the accompanying
drawing and will thereafter be pointed out in the
claims. .

In the drawing,
Fig. l is a front elevation of a portion of the
machine in which the present invention is'em
bodied;
Fig. 2 is a side elevation ofthe upper portion 55

2,111,606
of the mechanism shown in Fig. 1 as viewed from
the right; and
Fig. 3 is a detailed view partly in section of the
last-engaging abutment in an inoperative posi
tion.
The invention is illustrated herein as embodied
in a cement sole attaching machine of the type
disclosed in the Ballard et a1. patent mentioned
above. The machine is provided with a plurality
10 of pad boxes If) each of which is secured to a
bracket l2 formed on a turret (not shown) which
is arranged for intermittent rotation in a column
to present the pads in turn at an operating sta
tion. Each pad box 10 is provided with sole and
15 shoe-locating mechanisms 14 and It for respec
tively engaging the foreparts and heel portions
of a sole and shoe and positioning them rela
tively to each other on a yieldable pad 18 con
tained in the pad box.
The machine is also provided opposite each
pad with a forwardly and rearwardly swinging
member 20 for applying pressure to a sole and
shoe on a pad, this member being pivoted, as dis
closed in the patent referred to, on an axis lo
25
cated below and extending longitudinally of the
pad. Each swinging member carries levers
22, 24, pivoted on a shaft 26 and having rear
wardly extending arms 28 (Fig. 2) which are
arranged to be engaged by hydraulically operated
30 mechanism 35 which rotates the levers in a coun
terclockwise direction, as viewed in Fig. 2, to cause
the forward ends of the levers to descend toward
the shoe on the pad and, through means connect
ed to the forward ends of the levers, to press the
35 sole and shoe against the pad.
The lever 24 is arranged to operate a shoe
engaging abutment 25 mounted for sliding move
ment longitudinally of the pad in a T-slot 21
formed in a carrier block 29. The carrier block
29 is formed on the end of an outwardly extend
ing arm 3| pinned to a vertical shaft 33, this
shaft, as illustrated in the patent referred to,
being arranged for vertical sliding movement in
bearings in the sole attaching machine to im
45 part rectilinear movement to the abutment 25
as it moves toward and from the shoe, a spring
35 being provided on the shaft for returning the
shaft, the abutment, and the pressure-applying
lever 24 to inoperative position after the pressure
has been applied. The carrier block 29 is loosely
connected to the end of the lever 24 by a pin
and slot connection 3‘! which permits slight move
ment of the end of the pivoted lever relatively to
the abutment is located in a proper position for
engaging the forepart of the shoe on the pad.
In accordance with the invention disclosed
herein the pressure-applying lever 22 at the heel
portion of the pad is connected at its forward end 121
to a last-engaging abutment 44 arranged to be
moved into last-engaging position after the mem
ber 20 has been swung forwardly into pressure
applying position, thereby permitting the abut
ment 44 to be moved into operative position over
the last in a high shoe without dislocating or
distorting the portion of the upper which extends
above the last. The abutment 44 comprises a
curved arm secured by a set screw 45 (Fig. 3)
to a pivot pin 45 which is rotatably mounted in 15
a slide member 48 supported in a T-slot 58
extending longitudinally of the pad in a carrier
block 52, the carrier block being formed on the
end of an outwardly extending arm 49 (Fig. 2)
pinned to a vertical shaft 5| arranged for sliding
movement heightwise of the pad in the manner of
the shaft 33 and having a spring 53 thereon for
returning it to inoperative position. The car
rier block 52 is pivotally connected by a pin and
slot arrangement 54 to the outer end of the pres- ‘
sure-applying lever 22, thereby allowing move
ment of the end of the pivoted lever relatively
to the carrier block. The slide member 48 is
adjustable longitudinally of the pad in the T-slot
50 and is held in adjusted position by a friction 30
plug 56 (Fig. 1). At its upper end the abutment
“has a rearwardly extending forked portion 58
which is located behind the slide 48, as viewed in
Fig. 1. The slide 48 is provided at its right-hand
end with an outwardly and downwardly extend 35
ing arm 60 having a horizontal pin 51 rotatably
mounted therein to which is secured by a tapered
pin 64 (Fig. 3) a short curved arm 62. At its outer
end the curved arm 62 carries a pin 66 which is
located in the slot in the forked portion 58 of the
last-engaging abutment 44. Rotation of the shaft
6| and the curved arm 62 in either direction,
therefore, will swing the last-engaging member
44 in an opposite direction through the connec
tions described.
The pivot pin 6| extends through the arm 60
and is connected by a universal joint 68 to a
telescopic connecting rod 10 the lower end of
which is connected by another universal joint
12 to a rotatable shaft '14 extending horizontally
through the frame of the swinging member 20.
The shaft 14 extends beyond the inner side of the
member 20 and has fastened to its end a sub~
the carrier block as the lever rotates about its
stantially horizontal lever 15, the right-hand
pivot. The shoe-engaging abutment 25 has a
leather covered pad or cushion 34 at its lower end
for engaging the shoe upper.
The shoe-engaging abutment 25 is connected
end of which, as viewed in Fig. 1, is pivotally -
by a rod 36 to a lower arm 38 of a handle 40
60 pivoted in a boss 41 formed on the right-hand
side of the swinging member 20, this handle being
fulcrumed for limited rotation lengthwise of the
pad on a pin 42 to which it is secured, as will
later appear. In moving the swinging member 20
forwardly over the pad into position to apply
pressure to the sole and shoe, the operator grasps
the handle 40 and swings the member 20 for
wardly about its axis into a substantially verti
cal position after which the levers 22, 24 are
70 operated by the hydraulic mechanism 30 to apply
the sole-attaching pressure. After swinging the
member 20 into pressure-applying position the
operator can turn the handle 40 and pivot pin 42
to slide the shoe-engaging abutment 25 forwardly
75 or rearwardly of the pad IS in the block 29 until
connected by a pin 18 to an upwardly extending
link 80. At its upper end the link 88 is pivotally
connected by a pin 82 to a downwardly curved
arm 84 formed on a substantially T-shaped lever
86. The lever 86 has a forked portion which
straddles the hub of the handle 40 and is piv
oted on a pin 88 extending transversely through
the pin 42 upon which the handle 40 is pivoted
for movement lengthwise of the pad, thereby
securing the handle to the pin 42. The lever 85
has an upwardly and forwardly extending arm 90
(Fig. 2) the end 92 of which is enlarged and
located in a position to be engaged by the oper
ator’s thumb as he grasps the handle 48 to swing
the member 20 forwardly into pressure-applying
position.
The mechanism described is maintained nor
mally in inoperative position with the last-en
gaging abutment 44 elevated, as shown in Fig. 3,
by a tension spring 94 (Figs. 1 and 2) connected

horizontal. lever 16 and connected at, its lower
end to a screw 96. mounted'in. the swinging mem
ber 28. As shown in Fig. 3, the operative and
Before the member 20 is returned to inoperative
inoperative positions of the last-‘engaging abut
ment 44 are determined, respectively, by inclined
surfaces 98 and I88 formed on the slide member
48 and located in positions to engage correspond
ing surfaces on the last-engaging abutment 44.
The lower end of the last-engaging abutment
10
is provided with a laterally extending ?ange I02
which is somewhat wider than the top‘ surface of
a last at the forward or left-hand portion of the
abutment, as viewed in Fig. 1, but which at its
15 rear portion tapers to a relatively narrow end
which facilitates the movement of the abutment
through the opening in the upper as will pres
ently appear. Below the'?ange the member 44
has a relatively narrow last-engaging portion I 04
20 which is arranged to engage the top surface of
the last without contacting with the marginal
_portions of said surface.
In the operation of the mechanism an outsole
A‘is placed on the pad l8 with a shoe B on a last
25 C and the sole and shoe are positioned relatively
to each other on the pad by the positioning mech
anisms l4 and IS, the shoe and sole having ?rst
been treated with cement for permanently at
taching ‘the sole to the shoe bottom. The oper
30 ator then grasps the handle 40 of the swinging
member 20 and pulls this member forwardly
about its axis into a substantially vertical pres
sure-applying position. Before he operates the
mechanism 38 for lowering the pressure-applying
35 levers 22, 24, to press the sole and shoe against
the pad, he presses with his thumb against the
surface 92of the T-shaped lever 86 to swing this
lever in a clockwise direction, as viewed in Fig. 2,
about its pivot 88 against the action of the
40 spring 84. 'This lowers the link 88 and rotates
position, however, the tension spring 94 actuates'
the mechanism already described to swing the
abutment 44 in a clockwise direction, as viewed
in Fig. l, to return it to the inoperative position
shown in Fig. 3, the abutment passing through
the opening at the front of the shoe upper. The
action of the spring 94 is not su?iciently violent
to injure the moving parts because the spring is
just strong enough to overcome the weight of the
abutment 44 and the mechanism associated there
with and thereby to return the abutment effec
tively but without undue force into inoperative
position as soon as the pressure on the shoe is I
relieved. The abutment 44 will thus be moved
out of the way before the swinging member 28
moves rearwardly so that the portion of the
upper extending beyond the top of the last will
not be pulled or distorted by the return of the 20
pressure-applying mechanism into inoperative
position.
While the invention is disclosed herein as em
bodied in a machine for cement attaching soles
to shoes, it is not limited to such a machine and
may be utilized to advantage in other types of
machines adapted to perform various operations
on high shoes.
Having described my invention, what I claim
as new and desire to secure by Letters ‘Patent
of the United States is:
1. In. a machine for operating on shoes, the
combination of means for supporting a shoe, a
member movable transversely of the supporting
means into position over a shoe thereon for en- .
gaging a last in a high shoe, and means for
swinging said member when it is located over
the shoe into position to engage said last with
out distorting the portion of the shoe upper
which extends beyond the top of the last.
the horizontal lever 16 in a clockwise direction,
as viewed in Fig. 1. The shaft 14 to which- the
2. In a machine for operating on shoes, the
combination of means for supporting a shoe, a
lever 16 is fastened is‘ thus rotated and, through
swinging member for engaging a last in a high
shoe having an opening at the front of the shoe
upper, and means for swinging said last-engag 45
ing member laterally and longitudinally of the
supporting means into position to engage the last
without dislocating the portion of the upper
which extends above the top of the last.
3. In a machine for operating on shoes, the 50
the telescopic connecting member 10 and univer
sal joints B8, 12, rotates the‘ pin 6! and curved
arm 62 in a clockwise direction to swing the last
engaging member 44 from the position shown in
Fig’. 3 into the position shown in Fig. 1, thereby
bringing it directly over the top surface of the
last C.
"The abutment 44 passes readily through the
front opening in the upper which is notlaced
above the last by reason of the tapered rear por
tion of the flange I02. Moreover, since the for
55 ward portion of the flange is considerably wider
than the top surface of the last, it holds the op
posite sides of the upper adjacent to said top
surface away from the last, thereby permitting
the relatively narrow portion I84 of the abutment
60 to be in position to contact with the top of the
last without pinching the side portions of the
upper between it and the last. The operator
then causes the power of the machine to operate
the pressure-applying levers 22, 24 to lower the
abutments 44, 25 into pressure-applying engage
ment with'the last and shoe. When such action
takes place the operator may, of course, remove
his thumb from the T-shaped lever 86 since the '
abutment 44 is now ?rmly held in pressure-apply
70 ing position against the last.
' After the pressure has been applied to the sole
and shoe, the mechanism 38 of the cement‘sole
attaching machine operates to release the shoe
whereupon the abutments are elevated by the
75 springs 35, 53 and the swinging member 28 is
combination of a pad for supporting a shoe, a
member for operating on the forepart of a shoe,
a' pivoted member arranged to engage a last in
a high shoe for operating on the heel portion of
said shoe, means movable relatively to the pad
for supporting said pivoted member, and means
between the pivoted member and the supporting
means for swinging said pivoted member longi
tudinally of the pad through the opening at the
front of the portion of the shoe upper which ex
tends beyond the last and into’ position to engage
said last while the shoe is located in operative
position on the pad and while the last is free
from said pivoted member, thereby moving said
pivoted member into position to engage the last
without bending the upper over the top! of the
last.
