17 Claims. (01. 12-34)
This invention relates to machines for pressing is provided, as herein shown, a locking device
the bottoms of shoes and is herein disclosed in its arranged to permit the spindle to tip toward the
application to a leveling machine of the so-called toe rest as the saddle is forced against the shoe
automatic type.
but to lock the spindle against reverse tipping
5
In one well-known form of leveling machine movement in the pressure-applying operation. Oi
of the automatic type the leveling operation is In the illustrated construction the locking device
performed by relative movement of a leveling comprises a member which is'movable in one
tool or roll and a shoe support lengthwise of the direction in response to tipping movement of the
shoe and in the leveling operation the roll is spindle toward the toe rest, and a second mem
automatically controlled with respect to tipping
movement about an axis extending lengthwise
of the shoe to position it in proper relation to
different portions of the bottom of the shoe,
means being provided for varying the lengths of
the relative movements of the roll and shoe sup
port to accommodate shoes of different sizes and
for varying the relation of the shoe support to the
roll when the roll is tipped to compensate for
variations in the relative lengths of the fore
to part and shank portions of shoes of different
styles. The shoe support comprises a toe rest
provided with a rubber pad for engaging the toe
end of the shoe and a spindle arranged to en
gage the heel end of the last in its spindle hole.
The spindle is mounted for tipping movements
in directions toward and from the toe rest on a
heel post which is adjustable toward or from the
toe rest to position shoes of different sizes in
substantially the same relation to the leveling
30 roll.
Such machines are usually provided with spin
dle-tipping mechanism and with a so—called sad
dle of leather which is used to transmit the
pressure of the roll to the shoe in operating
upon certain kinds of work and is mounted for
movement into and out of operative position
over the bottom of the shoe for use alternatively
with the spindle-tipping mechanism to jack the
shoe, i. e., to force the toe end of the shoe ?rmly
against the toe rest. When the saddle is used
it is applied tightly over the bottom of the shoe
by depression of a hand lever, the spindle being
tipped somewhat toward the toe rest by the ac
tion of the last thereon as the saddle is thus ap
' plied and the toe end of the shoe is depressed
Ill)
ber which is movable into position to act as a
stop to prevent movement of the ?rst member in
a direction opposite to the direction in which it
is moved by the tipping of the spindle toward the
toe rest to lock the spindle against reverse tip
ping movement. More particularly, in the con
struction shown, there is provided a bell-crank
lever mounted for swinging movements about an
axis extending laterally of the shoe in response
to tipping movements of the spindle, and mount
ed for swinging movements about a different 20
axis extending laterally of the shoe is a seg
mental member the edge face of which is ar
ranged by engagement With a pin carried by
one arm of the bell-crank lever to prevent
swinging movement of the bell-crank lever in a
direction opposite to the direction in which it
has been swung by the tipping of the spindle to
ward the toe rest. Spring means is provided for
operating the segmental member and preferably,
as shown, the edge face of the segmental member 30
is eccentric to the axis of its swinging movement
for wedging engagement with the above-men
tioned pin. As illustrated, the segmental mem
ber is held against swinging movement when the
parts are in their initial positions by a latch, ‘-‘
and means is provided, in accordance with a fur
ther feature of the invention, for operating the
latch to release the segmental member to the
action of its operating spring by the movement
of the hand lever to force the saddle against
the bottom of the shoe. This means comprises
a member that is moved into and out of posi
tion to operate the latch by the movement of
the saddle into ‘and out of operative position
over the bottom of the shoe. In accordance
against the toe rest.
An object of the invention is to afford better
provided means for swinging the segmental mem
insurance that the shoe will be held against
displacement as the pressure of the roll is ap
ber against the action of its operating spring
out of engagement with the above-mentioned
plied through the saddle progressively along the
bottom of the shoe, and, more particularly, to
insure against tipping of the spindle in a direc
tion away from the toe rest by the pressure of
the roll on the upwardly inclined forepart of the
shoe bottom. For the purpose in View, there
with another feature of the invention, there is
pin and into ‘position to be held by the latch in '
response to the upward movement of the hand
lever to release the spindle for reverse tipping
movement.
The above and other features of the invention,
including various novel details of construction '
2
2,106,277‘
and combinations of parts will now be more par
ticularly described by reference to the accom
panying drawing and thereafter pointed out in
the claims.
In the drawing,
Fig. 1 is a view in side elevation of a portion
of a machine in which the invention is embodied;
Fig. 2 is a section on the line II-II of Fig. 1;
Fig. 3 is a view partly in rear elevation and
partly in section of parts of the locking device
for the spindle; and
Fig. 4 is a detail view of parts of the locking
device in their initial positions.
Since the invention is illustrated as applied to a
leveling machine of a well-known type only such
parts of the machine as it is necessary to refer
to for an understanding of the invention are
shown and will be described in detail. Features of
the general organization of machines of this type
are disclosed in various prior United States
Letters Patent including Letters Patent No.
1,667,761, granted on May 1, 1928, and No.
1,719,158, granted on July 2, 1929, both upon
applications of E. E. Winkley and H. A. Daven
port. It will be understood that the machine in
cludes an automatically controlled leveling roll
It and a shoe support or .jack which in the power
operation of the machine is moved automatically
in directions lengthwise of the shoe to cause the
roll to operate progressively along the bottom of
the shoe. The jack comprises a toe post i 2 and a
heel post l4 which are pivoted together for rela
tive adjustment for shoes of di?erent sizes by
means of a threaded adjusting rod (not shown)
which moves the heel post toward or from the
toe post so that the toeends of shoes of differ
ent sizes will be presented in substantially the
utilized to apply the saddle tightly over the bot
tom of the shoe in the same general manner as
illustrated in Letters Patent No. 1,263,361,
granted on April 23, 1918, upon an application
of W. C. Baxter, one of the arms 34 of the hand
lever being shown in Fig. 1. Each spring 39 at
its upper and lower ends engages spiral grooves
formed in pins 36, 38 which project respectively
from end members 46, 42, each member 40 being
pivotally connected to a plate 44 fastened to the 10
saddle 28 and each member 42 being pivotally
connected at 46 to one of the arms 34 of the hand
lever 32. To assist in holding the full—length
saddle in place there are provided additional
springs 48 connected to the opposite sides of the
forepart portion of the saddle and to the arms
34 of the hand lever 32. When the saddle is used
the lever 32, the arms of which are pivoted at 52
to blocks slidably mounted in slots 52 on the toe
post l2, pulls it down tightly over the shoe and is 20
then looked to a segment 54 on the heel post. The
slots 52 are concentric with the pivot about which
the heel post is movable toward or from the toe
post to permit relative adjustment of the toe and
heel posts without disturbing the relation between
the hand lever 32 and the heel post M.
The relation of the lever 32 to the spindle
tipping mechanism will now be described. As
more fully shown and described in the above
mentioned Letters Patent No. 1,719,158, there is 30
pivotally connected to the lower end of the heel
post M a link 55 having pivotally connected to its
upper end links 53, one of which is shown in
Fig. 1. The links 58 extend, one on each side of
the heel post i4, toward the toe post it’, and are ‘
connected to the arms 34 of the hand lever 32
by short upwardly extending links Eli. Depend
same relation to the roll I B. The jack as a whole
ing from the two links 58 are arms 62 connected
is operatively movable about the axis of a shaft
(not shown) on which the toe post is mounted
and power-operated means, not herein shown, is
by a horizontal pin 64 extending through a slot
66 formed in a member 68 connected to the lower
provided for imparting to the jack oscillatory
end of the link 26. Pivotally connected to the
member 68 is a U-shaped member 'Hl which may
movements about this axis to carry the shoe rear
be swung up into position to serve as an abutment
wardly and forwardly under the leveling roll. The
for the horizontal pin 64 or down, as shown in
Fig. 1. When the member 76 is in the latter
position the pin 64 has free movement in the slot
66 as the hand lever 32 is swung downwardly so
that no motion is imparted to the link 25 in oper
ating the saddle. When the member 70 is in its
toe and heel posts are provided with means for
supporting a shoe and last for the leveling opera
tion. Mounted on the toe post I2 is a toe rest
comprising a block I5 having secured to it a rub
ber pad 16 for engaging the toe end of the shoe.
The heel post l4 supports a block 20 carrying a
spindle 22 arranged to enter the spindle hole
in the heel end of the last. As shown, the block
20 is pivotally connected to the heel post for
swinging movements about an axis extending
laterally of the shoe to permit tipping movements
to be imparted tothe spindle in directions toward
and from the toe rest. The spindle 22 extends
through an enlarged opening in a plate 24 also
carried by the block 20 which plate is free to tip
about an axis extending laterally of the shoe to
adjust itself to the top face of the cone of the
last. The block 29 is connected by a link 26 to
mechanism which will presently be described
whereby the block and spindle may be swung to
press the toe end of the shoe ?rmly down upon
the toe rest.
For use in jacking a shoe alternatively with
the spindle-tipping mechanism just referred to
there is provided, as heretofore in machines of the
type herein shown, a saddle 28 of ?exible leather
which, as illustrated, is of such length as to cover
the entire bottom of the shoe and is connected
at the opposite sides of its shank portions by
springs 30, one of which is shown in Fig. 1, to the
two arms of a bifurcated hand lever 32 which is
uppermost position, in which position it is held by
the engagement of a spring-pressed pin 72 in
the member 68 in a recess '14 in the member 7!],
downward movement of the handlever 32 forces
the link 25 downwardly to operate the spindle by
engagement of the pin 64 with the member "Hi.
The spindle 22 is normally held tipped toward the
toe support by means of a spring "it extending
between one of the links 58 and a pin 78 project
ing from the link 26. The mechanism for thus
rendering the hand lever 32 effective to operate
either the saddle 28 or the link 26 is substantially
the same as that shown and described in the
above-mentioned Letters Patent No. 1,719,158.
For purposes of this invention there is provided
mechanism which is operative when the saddle is
over the shoe bottom to permit the spindle to tip
toward the toe rest as the saddle is forced against
the shoe but .is arranged to lock the spindle
against reverse tipping movement in the pres
sure-applying operation of the roll. Pivotally
connected to the heel post M (Fig. 1) is a bell
crank lever 80 provided with a rearwardly ex—
tending arm 82 which is slotted to receive the
link 26 and carries a pin 84 extending through the
link (Fig. 2), The bell-crank lever 80 has a
3
2,106,277
downwardly and forwardly extending ‘arm 86
carrying a pin 88. Secured to the heel post I 4
by screws 99 is an angularly-shaped plate 92 to
which there is fast a stud 94 (Fig. 3) and upon
this stud there is pivotally mounted a segmental
member or wedge 96. A spring 98 coiled about
the stud 94 tends to impart to the member 96
a swinging movement relatively to the plate 92 in
a counterclockwise direction (Fig. 1). Project
10 ing from the plate 92 above the stud 94 is a pin
99 upon which there is rotatably mounted a latch
I96 provided with a notched end I02 which is
arranged to engage a pin I04 projecting from the
member 96 to hold the member 96 against
swinging movement when the parts are in their
initial positions. A spring I06 coiled about the
hub I08 of the latch I90 tends to impart to the
latch a swinging movement in a direction to hold
its notched end I02 in engagement with the pin
I04. When the hand lever 32 is in its initial posi
tion, with the saddle 28 in position over the bot
tom of the shoe, a plate IIIl fast to the member
42 is arranged to overlie a second arm H2 pro—
jecting from the latch Illll (Fig. ll). As the hand
lever 32 is swung downwardly to apply the saddle
28 tightly over the bottom of the shoe through
the springs 39 and 48, the plate II ll acts by en'
gagement with the arm I I2 to swing the latch I89
against the resistance or" the spring H16 in a di~
rection to move the latch out of engagement
with the pin I04 and to release the member 95 to
the action of the spring 98. As the saddle is thus
applied tightly over the bottom of the shoe by
downward movement of the hand lever 32 the
pressure of the saddle on the shoe acts to force
the toe end of the shoe into the rubber pad I8
oi the toe support, the spindle 22 and block 29 be
ing tipped toward the toe support by the action
of the last thereon as the toe end of the shoe is
thus ?rmly seated on the toe support. Tipping
movement of the block 29 toward the toe sup
port causes the link 26 to move downwardly,
thereby imparting to the bell-crank lever 80 a
swinging movement in a counterclockwise direc
tion (Fig. 1). As the bell-crank lever 80 is thus
swung by the downward movement of the link
29, the member 96 is also swung in the same. di
rection by the spring 98. this movement of the
member 96 being limited by the engagement of
its edge face IIll with the pin 88 carried by the
arm 86 of the bell-crank lever 80. The edge face
H4 of the member 96 is eccentric to the axis of
the stud 94 on which the member 96 is pivotally
mounted, the spring 93 acting to force the edge
face I I4 against the pin 88 with a wedging action.
In order to permit the member 96 to be swung by
the spring 99 into position to lock the bell-crank
lever 89 and the link 25 in whatever position
they assume by tipping of the spindle 22 when
(.10 the saddle is forced down on the shoe without in~
terference between the member 98 and the spring
I96, the member 96 has a slot II6 formed there
in concentric with the axis of the stud 94. As
the member 96 is swing in a counterclockwise
direction by the spring 98 the pin IM acts by
engagement with the latch I00 to hold the latch
against swinging movement in a clockwise direc
tion. If in operating on any shoe the pin I94
releases the latch I09 for clockwise swinging
movement, a second pin II? projecting from the
member 96 holds the latch against such swing
ing movement. It will be evident from the above
description that with the lever 32 locked to the
segment 54 the spindle and block 20 are locked
75 against reverse tipping movement from the posi
tion into which they have been moved by the last
by the. engagement of the member 95 with the pin
88. Thereafter in the‘power operation of the
machine as the jack is swung in‘ directions
lengthwise of the shoe under the leveling roll It
the last and shoe are held by the spindle 22
against displacement in a direction away from
the toe rest as the pressure of the roll H1 is applied
through the saddle 28 to the upwardly inclined
bottom surface of the forepart of the shoe.
10
For swinging the member 96 in a direction to
release the block 20 and spindle 22 for reverse
tipping movement to permit the shoe and last to
be removed from the jack after the'completion of
the pressure-applying operation, the member 95
has a rearwardly extending portion I20 which is
arranged to be engaged by a laterally extending
projection I22 on the hand lever 32 in the upward
movement of the hand lever. When the hand
lever 32 is unlocked from the segment 54 and. 20
swung upwardly to idle position the projection
I22 on the hand lever by engagement'with the
rearwardly extending portion I2ll of the member
96 swings the member 96 in a clockwise direction
far enough to move the pin I04 into position to
be again engaged by the notched end I62 of the
latch Hill, the arrangement of the parts being
such that with the member 96 locked by the latch
against swinging movement in a counterclockwise
direction the bell-crank lever all is free to swing 30
relatively to the member 96 without interference
between that member and the pin 88.
The pivotal connections 45 between the mem~
bers 4'2 and the arms 34 of, the hand lever 32
permit the saddle 23 to be swung either to an '
idle position at- the front of the heel post, in which
position it is usually draped over thehand lever
32, or to an operative position over the bottom
of the shoe as shown in Fig; 1. As the saddle
is swung to its idle position the plate i It is moved 40
into a position in which it will not contact with
the arm II2 of the latch I08 when‘ the hand lever
32 is swung downwardly. It will be readily seen
that with the saddle in its idle position the shoe
support may be used as heretofore in jacking the
shoe by swinging the U-shaped member it up
wardly into position to be engaged by the pin Ed
in the downward movement of the hand lever 32.
It will be understood that the member 96 is held
against swinging movement when the‘ saddle is
in idle position by engagement of the latch Hill
with the pin I04.
~
’
When it is desired to use the saddle 28 the
U-shaped member "I9 is swung downwardly into
the position shown in Fig. 1 and the saddle 28 I
is moved into position over the shoe by swinging it
forwardly. It will be understood that before the
saddle is moved into position over the shoe the
operator will mount a shoe and last on the spindle
22 and will swing the spindle .22 and block 29
against the resistance of the spring ‘I6 in a direc
tion away from the toe post I2 by elevating the
toe end of the shoe into position to engage the
rubber pad I8 on the toe ‘support. Thereafter,
with the saddle in position over the bottom of the
shoe, the hand lever 32 is swung downwardly to
apply the saddle tightly over the shoe and to force
the toe end of the shoe ?rmly against the rubber
pad I8, thus causing the spindle to tip toward the
toe rest by the action of the last thereon. This
movement of the hand lever 32 causes the plate
III] by engagement with the arm I I2 to swing the
latch Hill in a direction to release the member
96 to the action of the spring 98. The ‘member
96 is then swung; by the spring 98 in a counter
4
2,106,277
clockwise direction (Fig. 1) until its edge face
I I4 is wedged against the pin 88 in whatever posi
movement of said ?rst-named member in the
tion the lever 80 may assume in response to the
reverse tipping movement in the pressure-apply
tipping of the spindle 22 toward the toe rest as
the saddle 28 is forced against the bottom of the
shoe, thus locking the block 20 and spindle 22
against reverse tipping movement with the hand
lever 32 locked to the segment 54. Thereafter,
ing operation.
as the hand lever 32 is swung upwardly to idle
position after the completion of the pressure
applying operation, the projection I22 on the hand
lever acts by engagement with the rearwardly
extending portion I20 of the member 96 to swing
the member out of engagement with the pin 88
and into position to permit the notched end I02
of the latch IBIl to engage the pin I04, after which
the last and shoe are removed from the machine.
