United Shoe Machinery Corporation, Paterson,
N. J., a corporation of New Jersey
Application May 21, 1937, Serial No. 144,008
10 Claims.
This invention relates to lasting machines and
more particularly to machines for lasting the
heel ends of shoes. The invention is herein il
lustrated as applied to a machine constructed
5 generally as disclosed in United States Letters
Patent No. 2,059,241, granted on November 3,
1936 upon an application of mine, but it is to be
understood that it is not limited in utility to
machines of that particular character.
10
As shown in the above-mentioned Letters Pat
ent, heel-end-lasting machines are commonly
provided with wipers for wiping the marginal
portion of the heel end of the upper materials
inwardly over an insole or other shoe bottom
part on the last, and with a holddown for en
(o1. 12-4)
shoe after the lasting operation this latch is ren
dered inoperative, whereupon the relatively mov
able parts resume their normal relation to each
other under the inñuence of a spring.
The novel features of the invention will now
be more particularly described with reference
to the accompanying drawing and thereafter
pointed out in the claims.
In the drawing,
,
Fig. 1 is a View in left-hand‘side elevation,
with parts broken away, of a portion of a ma
chine provided with mechanism constructed for
purposes of the present invention;
Fig. 2 is a similar view of a portion of the
mechanism as it appears after its movement to 15
gaging the bottom of the heel end of the shoe
to determine the relation of the shoe to the
plane of the wipers. It occasionally happens
adjust the holddown;
that the upper materials of a shoe are not as
Fig. 4 shows a portion of the machine in iront
elevation and illustrates the relation of a shoe
sembled in the best relation, so that the inturned
iiange of the counter is not well down on the
insole but is spaced therefrom in one or more
locations around the heel seat when the shoe
comes to the heel-end-lasting machine. If the
wipers operate on such a shoe in a plane as close
to the insole as on a properly assembled shoe,
there is danger of damage to the outer layer of
the upper materials because of the resistance of
the comparatively stiff counter to the movement
'30 of the wipers. An object of the present inven
tion accordingly is to provide means adapted for
quick and convenient use to change the relation
Fig. 3 is a sectional view of certain parts shown
in'Figs. 1 and 2;
to the holddown, and
Fig. 5 is a perspective view of the heel end of
a shoe in the lasting of which the mechanism
provided by the invention may be advantageously
utilized.
In view of the disclosure of the previously
mentioned Letters Patent, only such parts of the
general organization of the machine to which
the invention is shown as applied as itis neces
sary to refer to for an understanding of the in 30
vention are illustrated in the drawing or will be
hereinafter mentioned. The machine is provided
between the wipers and a shoe to meet such spe
with power-operated wipers 2 movable in a fixed
cial conditions. The construction herein shown
comprises novel mechanism for effecting a quick
adjustment of the holddown from a normal po
plane to wipe the marginal portion of the heel
sition in a direction to space the insole farther
from the plane of the wipers in the wiping oper
ation so that the Wipers will operate with less
40 pressure on the upper materials, and automatic
end of the upper materials inwardly over the in
sole, and associated with the wipers is mecha
nism, not shown in detail, for driving a gang of
tacks to fasten the upper in lasted position. The
shoe is supported on a jack 4 and is clamped
around its heel end by a heel band 6. The jack 40
means for returning the holddown to normal
is swung about a horizontal axis to carry the
position after the lasting operation so that the
machine will be in condition to operate next,
shoe to a'position within the heel band and is
raised to force the shoe against a holddown 8
which engages the heel end of the insole. The
holddown is vertically movable in a ‘guideway in 45
as usual, on a properly assembled shoe. In ma
45 chines constructed as disclosed in the above
mentioned Letters Patent the holddown is con
trolled by power-operated mechanism which op
erates it to depress the shoe both prior to and
after the operation of the wipersthereon, and
for purposes of the present invention the above
described adjustment of the holddown is effected
by relative movement of parts of this mechanism,
a latch being provided for preventing reverse rel
ative movement of such parts. In response to.
55 the movement of the mechanism to depress the
a bracket IU on the frame of the machine and
is provided with rack teeth l2 in engagement
with a pinion I4 formed integral with a shaft
I6 which is rotatable in bearings in the bracket.
Also integral with the shaft I6 is a spiral gear
I8 in engagement with teeth on a horizontal slide
20 mounted in a guideway in the bracket l0. This
slide is operatively related, as hereinafter de
scribed in detail, to a bar 22 the rear end of
which is slidingly mounted in a recess 24 formed
2
2,115,722
in a slide 25 movable in a guideway in the frame.
The slide 26 carries a roll 28 arranged to be
engaged by a rotatable cam 3l). Mounted in a
recess in the bar 22 is a light spring 32 which
bears at its rear end against the slide 26 and
tends by its expansion to move the bar 22 and
10
15
20
25
the slide 20 forwardly and thus to lower the
holddown 8 by turning the shaft I6. This move
ment is normally limited by engagement of a
lug 34 on the bar 22 with a plunger 36 controlled
by a spring 38 mounted in the lower end of a
lever 40 which is pivoted at 412 on the frame as
and for purposes described in the previously men
tioned Letters Patent. When the jack 4 is raised
to force the shoe against the holddown, thev hold
down is lifted by the shoe and the bar 22 is moved
rearwardly against the resistance of the spring
32 until a flange 44 on the bar engages the for
ward end of the slide 26. Thereafter, in the
power operation of the machine, the cam 35 acts
through the slide 26 to depress the holddown and
the shoe and thus to cause the heel band to wipe
the upper upwardly before the band is closed
firmly against the shoe. The holddown then de
termines the height of the bottom of the heel
end of the shoe relatively to the plane of the
wipers 2 as the wipers are operated to wipe the
marginal portion of the upper materials inwardly
over the insole. After one such overwiping move
30 ment of the wipers they are retracted and are
then operated again to apply a second wipe to
the upper, prior to which second wipe the shoe
and the holddown are raised slightly by the jack,
as permitted by the cam 30, to increase the pres
35 sure of the wipers on the shoe.
After the driv
ing of the upper-fastening tacks the holddown
is depressed by the cam 30 to a lower position
than at any previous time in the cycle to force
the shoe away from the wipers before the latter
40 are retracted from over the shoe bottom, where
upon the parts of the machine resume their
starting positions.
As thus far described, the construction and op
eration of the ‘machine are as disclosed in the
45 previously mentioned Letters Patent. As also
therein disclosed, the machine is provided with
means for eifecting an initial vertical adjustment
of the holddown to vary the position of a shoe
heightwise relatively to the plane of the wipers.
50 This means comprises a sleeve 46 threaded in
the bracket I0 and mounted to turn on the shaft
I6 between one end of the spiral gear I8 and a
collar 48 fast on the shaft. It will be understood
that turning of the sleeve 46 serves to move the
55 shaft I6 lengthwise and that such movement of
the shaft causes it to turn and` adjust the hold
down by reason of the engagement of the spiral
gear I8 with the teeth on the slide 26. This ad
justment is required, for example, when there is
60 a substantial difference in the> thickness of the
upper materials as between different lots ,of
shoes ; and it will be evident that when thus ad
justed to position a shoe in a particular relation
to the wipers, the holddown will position every
65 shoe in that relation until it is diiferently ad
justed.
It sometimes happens, however, that some par
ticular shoe should be positioned differently than
other shoes of the same lot, in order to avoid
70 danger of damage to the upper materials in the
lasting operation. In the shoe shown in Fig. 5
of the drawing, for example, portions a of the
inturned ñange of the counter are buckled so
that they are spaced considerably above the in
75 sole. This may have been caused by the lifting
of the wings of the counter prior to the side last
ing operation, necessitated by improper assem
bling of the upper materials. It is desirable that
such a shoe be positioned slightly lower than a
shoe in normal condition during each overwip
ing movement >of the wipers, so that' the wipers
will apply somewhat less pressure to the upper.
The present invention, accordingly, provides
means for effecting a quick adjustment of the
holddown in a downward direction to meet such 10
special
conditions,
together
with
automatic
means for returning the holddown to normal
positiony for use on the next shoe. For the pur
poses in view the rear portion of the slide 20 is
bifurcated to receive between spaced arms there 15
of a forwardly projecting tongue 50 on the bar
22, and a pin 52- carried by the slide extends
through a slot 54 in the tongue. A spring 56
mounted in a recess in the forward end of the
slide 20 and engaging a stop 58 on the bracket I0 20
normally holds the rear end of the slide in en
gagement with shoulders 60 on the bar 22 at
the opposite sides of thetongue 50. Within the
limits of the pin and slot connection between the
slide and the bar, however, the slide may be 25
moved forward relatively to the bar to adjust
the holddown in a downward direction. For thus
moving the slide 20 there is provided a lever 62
fast on a pin 64 mounted to turn in bearings in
the bracket l0, the lever having a bifurcated 30
lower end embracing a stud 66 mounted in the
bifurcated portion of the slide (Fig. 3). The
stud is held fast to one of the arms of the slide
by a nut 68 which forces a collar 10 against one
side of that arm and forces a shoulder 'l2 of the
stud against the other side of the arm. The
lever 62 is operated by a plunger T4 which is
mounted in the bracket l0 and has on its forward
end a head 16 arranged to be engaged by the
hand of the operator, the plunger being rear
wardly movable against the resistance of a spring
18. To maintain the holddown in adjusted posi
tion there is loosely mounted on an eccentric por
tion 80 of the stud 66 a latch 82 the rear end
of which normally rests on a ledge 84 of the 45
tongue 50, as shown in Fig. 1, but enters a notch
86 in the tongue when the slide 20 is moved for
wardly by the lever 62, as shown in Fig. 2. A
spring-pressed plunger 88 engaging the top of
the latch insures such downward movement of. 50
the latch.Y It will be evident that the latch pre
vents the slide 20 from being returned by the
spring 56 to its initial position in relation to the
bar 22 and that in the power operation ofthe ma
chine the slide is operated to depress the hold
down in the manner previously described by the
engagement of the tongue 50 of the bar with thel
end face of therlatch. The position of the hold
down determined by the latch may be varied byv
turning the stud 676 after loosening the nut 68, 60
the latch being mounted on an eccentric portion
80 of the stud as previously described. In order
to permit return of the holddown to its initial
position by the spring 56 after the lastingoper
ation, the latch 82 is swung upwardly out of the 65
notch 86 near the end of the cycle of operations of
the machine. For this purpose there is threaded
in the bracket l0 a rod 90 the rear end of which
is arranged to engage and >act as a stop on a
depending tail 92 of the latch in response to 70
forward movement of the slide 20. The rod 8U.
is so adjusted that it does not affect the latch
until that time in the cycle when the hold
down is operated to depress the shoe away from
the wipers after the lasting operation, at which
3
2,115,722
time the slide 20 is moved farther forwardly
than at any previous time in the cycle. It will
be understood that when the latch is lifted the
spring 56 returns the slide 20 into engagement
with the shoulders Si) of the bar 22, and there
after, as the cam 3i) permits, returns the hold
down to the position which it occupied prior to
its adjustment by the plunger 14.
