Application January 27, 1945, Serial No. 574,355
7 Claims. (01. 12-12)
This invention relates to lasting machines, and
is herein illustrated as applied to a machine con
structed generally as disclosed in United States
Letters Patent No. 1,843,232, granted on February
2, 1932, on an application of B. Jorgensen’s, but
modi?ed in certain respects as further disclosed
especially in Letters Patent No. 2,026,539, granted
on January 7, 1936, and in Letters Patent No.
2,075,852, granted on April 6, 1937, on other
applications of B. Jorgensen’s. Machines of
that character are frequently used, as herein
shown, for lasting tennis shoes or the like
which are commonly made on metal lasts
and in which the uppers are secured to in
soles by adhesion. It is to be understood,
however, that the invention is not limited to the
manufacture of shoes of that kind or, in some
aspects, to machine organizations such as dis
closed in the above-mentioned Letters Patent.
A machine such as that to which the invention -
is herein shown as applied is provided with toe
lasting means including a gripper which is closed
by a treadle on the margin of the toe end of the
upper prior to the starting of the power operation
of the machine and serves thereafter to pull the
upper in response to downward movement of the
last effected by pressure applied to an insole on
the last. The last with the upper and the insole
thereon is mounted on a toe rest and on a heel
_

.
machine after the closing of the gripper on the
toe end of the upper by the treadle. In order
to save time and thus to increase the output of
the machine, and also to avoid such objections as
there may sometimes be to, the use of the knee
for releasing the heel carriage, especially if the op
erator is a Woman, the construction herein shown
is such that the treadle which is used to close the
toe gripper is used also to release the heel car
riage. For this purpose there is provided a lever
arranged to act on the above-mentioned plunger
and a lost-motion connection between this lever
and the treadle for operating the lever by further
movement of the treadle after the closing of the
toe gripper, the gripper-closing mechanism being
so constructed as to permit such further move
ment of the treadle. By what may be, there
fore, a practically continuous movement of the
treadle, the operator ?rst closes the toe gripper
and then releases the heel carriage, thus saving
a substantial amount of time as compared with
previous practice as well as eliminating the need
for use of. the knee.
The above and other features of the invention,
including various novel details of construction
and combinations of parts, will now be more par
ticularly described with-reference to the accom
panying drawings and thereafter pointed out in
the
claims.

tioned Letters Patent, only such portions of the
machine as it is necessary to refer to for an un
derstanding of the invention will be herein par
ticularly described. The machine herein shown
is constructed for lasting only the toe and heel
ends of the shoe, the side-lasting mechanisms
sometimes included heretofore in machines .of
the illustrative type being omitted.
For supporting the last and shoe the machine 10
includes, as heretofore, a slide 2 movable down
wardly against the resistance of a spring 4 by
pressure applied on the bottom of the heel end
of the shoe and a toe rest 6 movable downwardly
against the resistance of aspring .8 by pressure

to the pins 46 and to brackets 54 fast on the
cover plate 34 tend to pull the blocks 38 and. the
arms 28 bodily in a direction lengthwise of the
shoe away from the toe end of the shoe and also
tend to swing the blocks and the arms about
the axis of the shaft 32 in the direction to lift
the clamp member 26 away from the member 24.
Such bodily movement of the blocks and the arms
in a direction away from the toe end of the shoe
is limited by contact of the shaft 32 with the
arms in the slots 36 formed in the latter, and
such swinging movement about the axis of the
shaft 32 is limited by contact of the tail portions
44 of the arms with the cover plate 34. When
the parts are in these initial positions the clamp
applied on the bottom of the toe end of .the shoe. 15 member 26 is both lifted and retracted length
The shoe and its supporting means are thus moved

of the insole respectively. The toe presser-foot
Movement of the clamp member 26 into clamp
ing position is effected by turning the shaft 32
is supported on an arm 14 which by means of a
handle [6 is swung forwardly by the operator to
carry the toe presser-foot to a position over the
toe end of the shoe, whereupon the machine is
started and the arm is moved downwardly to
carry the presser-foot into engagement with the
insole and to impart to the toe end of the shoe
its downward movement. As the toe presser-foot
is thus moved downwardly the heel presser-foot
is swung automatically to a position over the heel
end of the shoe and is ‘moved downwardly to
depress that end of the shoe.
The toe-lasting mechanism includes a toe band
is which embraces the upper about the toe end
of the last and wipes the upper heightwise of the
last in response to the downward movement of
the last, and also includes toe-embracing wipers
26 (Fig. 2) which are thereafter operated to wipe
the margin of the toe end of the upper inwardly
over the insole into position to adhere to the in
sole. Further included in the toe-lasting mech
in a clockwise direction with reference to Figs.
1 and 5. At the beginning of such movement of
25 the shaft the crank arms 56 act'through the links
48 to move the blocks 38 and the arms 28 length
wise of the shoe against the resistance of the
springs 52 as far as permitted by engagement of
the shaft 32 with the arms in the slots 38 in the
30 arms, thus advancing the clamp member 26
lengthwise of the shoe before it begins its down
ward swinging movement. When the lengthwise
movements of the arms 28 are stopped by the
shaft 32 the links 48 begin to swing the blocks
35 38 and the arms as a unit about the axis of the
shaft 32 to carry the clamp member 26 into
clamping engagement with the upper, and after
this member has engaged the upper the blocks 38
are swung, by further movement of the links,
40 about the rod 36 against the resistance of the
springs 42, so that the clamp member is held
yieldingly against the upper through these
springs. The turning of the shaft 32 is effected
by the operator by depression of a treadle 56
(Fig. 1) against the resistance of a spring 58, the
anism is a device 22 which serves as a toe gripper
and which clamps or grips the marginal portion
of the toe end of the upper and applies a pull to
the upper in response to the downward move
ment of the last. This device, in accordance gen
erally with the disclosure of Letters Patent No.
2,075,852, comprises a lower clamp member 24
(Fig. 5) curved to extend around the end of the
treadle being connected by a flexible cable 66 to
one arm of a lever 62 fast on the shaft 32. Piv
otally mounted on the other arm of this lever is
toe and having an upper-clamping portion 10- '
cated immediately over the wipers 26, and a co
operating clamp member 28 movable relatively
to the member 24 to clamp or grip the margin
of the upper ‘positioned by the operator between
these members. The clamp member 26 is se
~cured to two arms 28 (Fig. 2) which serve as a
holder therefor, these arms having therein slots
30 through which extends a shaft 32 supported
in bearings on the top of a cover plate 34 posi~
tioned over the wipers, so that the arms may not
only swing with the clamp member about the
axis of this shaft but may also move lengthwise
relatively to the shaft. Extending through the
a ?nger 64 controlled by a compression spring
86 (Fig. 2) which tends to swing the portion of
the ?nger below the lever toward a lug 68 (Fig. 1)
formed on the lever. Initially the ?nger is held
by the spring with one side thereof in contact
with a lug 19 formed on a plate 12 which is fast
55 on one end of a rockshaft 14 whereby the toe
wipers 26 are operated. When the operator de
presses the treadle to effect the clamping or grip
ping of the toe end of the upper the ?nger 64 is
carried upwardly by the lever 62 past the lug ‘I6,
whereupon the spring 66 swings the lower end of
the ?nger to a position over the top of the lug
as shown in'Flg. 1, such swinging movement of
the ?nger being limited by contact of the lug 68
on the lever 62 with the end of a screw 16 carried
arms 28 is a rod 36 (Fig. 5) on which are piv
by the ?nger, The clamp member 26 is thus
otally mounted two blocks 38 provided with 65 locked in clamping position by the engagement
plungers 40 arranged to bear against shoulders
of the lug 16 with the ?nger 64, so that the op
on the arms 28 above the rod 36 and controlled

52. The means thus described for gripping and
for applying a pull to the toe end of the upper
is constructed mainly as disclosed in the pre
viously mentioned Letters Patent No. 2,075,852.
-As further described in detail in Letters Patent
No, 2,026,539, the previously mentioned vertically
movable shoe support slide 2 carries at its upper
end a slide ‘I8 (Figs. 1 and 3) mounted for move
depending arm I44 the lower end of which is in
the path of the horizontally movable heel car
riage 96. Accordingly, when the carriage is
moved outwardly to its initial position where it
is held by the latch I02, as it is automatically
near the end of the cycle of operations of the
machine through connections including a chain
I46 as heretofore, it acts through the arm I44,
ments in directions lengthwise of the shoe along
the pinion I40 and the crank arm I36 to move
guideways 80 on the slide 2. Supported by the 10 the link I34 toward the left (Fig. l) and thereby

rods 94 and abutting against the slide 2. Sub

The lever IIO which carries the latch I02 is
normally held up against the lug I04 on the heel
along the guideways 80. For controlling the slide
carriage 96 by a. spring I64 connected to a rod
18 there is provided another slide I I6 movable in
directions lengthwise of the shoe along a guide (rid I66 which is pivotally connected at its upper
end to the lever. The rod extends downwardly

rotatably mounted in the slide II 6. The shaft
I26 is provided with screw threads engaging co
operating threads in a nut I28 mounted in a re
cess in the slide ‘I8. On the shaft I20 is a hand
wheel I30 for turning it. It will thus be seen that C J
by tnrning this hand wheel the slide ‘I8 may be
adjusted in directions lengthwise of the shoe rela
tively to the slide I I6, and that by the adjusting
means the slide ‘I8 and the slide II 6 are held
in ?xed relation to each other so as to be mov
able as a unit in directions lengthwise of the
shoe.
Pivotally connected at one end to a pin I32 in
the slide I I6 is a link I34 which is pivotally con
gaged by the arm I68 to impart downward move
ment to the rod and thereby to release the heel
carriage from the latch I02 in response to turn
ing movement of the rockshaft I70 in a counter
clockwise direction with reference to Fig. 6. For
imparting such turning movement to the rock
shaft there is also fast thereon an arm I14 pro
vided with a roll I16 engaged by an inclined face
I18 formed on a lug I88 which is part of a bar
I82 movable lengthwise in a bracket (not shown).
A member I84 extending upwardly from the
front end of the bar I82 is engaged by the rear
end of a rod I86 slidingly mounted in a bearing
in the frame and having fast thereon a plunger
nected at its other end to a crank arm I36 (Fig. -

bracket I08. On the hub of this crank arm are
gear teeth in engagement with a pinion I40 which
is fast on a shaft I42 also mounted to turn in
the bracket I08. Fast on the shaft I42 is a
response, therefore, to rearward movement of
the plunger I88 the heel carriage is released as
described, the rearward movement of the barv

The plunger I88 has been provided heretofore
with a pad arranged to be engaged by the knee
of the operator to e?ect the release of the heel
carriage after the depression of the treadle 56
to close the toe gripper 22 on the upper. To save
time in the operation of the machine and also to
the heel-end portion of the last. The plate 236
is held in different adjusted positions, as may be
required by shoes of different sizes, by a bar 242
(Fig. 9) and a screw 244 extending through the
bar and threaded in the plate 230. The bar has
at its opposite ends upraised portions engaging
the opposite side portions of the plate 236 under

In the use of the machine, in so far as it is of
interest with reference to the present invention,
the operator takes a shoe which, as herein shown,
will usually have been already side lasted from
its toe-end portion to its heel-end portion and
10
Novel'features relating more particularly to the
means herein disclosed for supporting the heel
end of the last and for controlling the last with
respect to lengthwise movement are claimed in a
divisional application, Serial No. 607,813, ?led on
July 30, 1945.
Having described the invention, what I claim
as new and desire to secure by Letters Patent of
the United States is:
1. In a lasting machine, a'device for gripping
the marginal portion of the toe end of an upper
on a last, an operating member movable by the
operator to close said device on the upper, an
other device for clamping the heel-end portion of

port. If the shoe is one of the Oxford type, as
ing said clamping device lengthwise of the last
shown in Fig. 1, the block 248 will have been
into position thus to clamp the upper, means for

depending upon whether the shoe is a right or a
left shoe, shifts the block 223 and the parts there
on to a position determined by engagement of
one or the other of the stops 256 with the plate
236. In presenting the work the operator also
positions the margin of the toe end of the upper
outspread between the jaws of the toe gripper

sented the operator closes the toe gripper on the _

(Fig. 1) is moved downwardly to release the heel
for clamping the heel-end portion of the upper
carriage es, whereupon the heel carriage is moved
against the last, spring means for moving said
by the spring I06 to the position determined by
its engagement with the washers H4 (Fig. 3),
thus carrying the heel band I00 toward the shoe.
Near the end of this movement of the heel car
riage the latch I54 is operated to release the slide
18 to the action of the spring I 48 which moves the
slide and the parts thereon to carry the shoe to
ward the heel band and thus to cause the heel
band properly to engage the heel end of the shoe.
Such movement is imparted ‘to the shoe by the
engagement of the upstanding portion 238 of the
plate 236 with the last or with the upper thereon,
the operator at this time still holding the shoe
down on the heel-end support with his hand.
The operator then starts the power operation of
the machine by swinging the arm l4 forwardly,
and the machine lasts the toe and heel ends of
the shoe in a manner which need not be described
herein in view of the disclosures of the previous
ly mentioned Letters Patent. It will be under
stood that after depression of the treadle 56 for
the purposes above described the operator re
leases it to permit it to be returned to its initial
position by the spring 58, the toe gripper being
held closed on the upper by the engagement of
the lug 19 (Fig. 1) With the finger 64. Upon the

from its clamping position, mechanism including
a plunger movable to release the clamping device
to the action of said spring means, and means for
thus moving said plunger by the movement of
said operating member.
