3 Claims.
This invention relates to machines for ‘use in
' lasting shoes and is herein ‘illustrated in. its ap
(01,, 12-141)
,
,
which are movable lengthwise of the last to ad
vance the band and are also mounted for swing
plication to means for lasting thertoes of shoes.
A well-knowntype of‘ bed lasting machine in
ing movements toward and from each other to
close and open the band. Since the band is
common use ‘includes in .itslorganization toe
molded substantially to conform to the contour ‘
embracing wipers for wiping the upper ?rst
heightwise of the toe and then inwardly over the
of the toe end'of the last, its closed end por
tion has a substantially ?at upper-engaging face
which is substantially as wide as the toe-end face
of the last and is adapted to press the upper
against the toe-end face of the last as the band- i
is advanced lengthwise of the last, the ?exible
corners of the band permitting its side portions
to, be swung toward each other to press the
upper against the lateral faces of the last at the
shoe bottom and a toe-end-clampingdevice or
band which is advanced and closed about the
toe to clamp the upper around the toe end of
the last after the upwiping operation as the
wipers are moved inwardly over the shoe bottom.
In operating upon shoes mounted upon square
toed lasts, that is, lasts the toe end faces of
which are substantially straight widthwise of
the last and form with thelateral faces of the
lasts relatively sharp‘ corners, considerable di?i
culty has been experienced heretofore in clamp
ing the upper smoothly. around the toe end of
20 the last‘ by the use of the usual substantially U
shaped clamping band, commonly provided in
machines of the type above referred ‘to, since
the clamping hand because of its shape-tends to
wipe the upper rearwardly of the last at the
225 opposite corners of the toe as it is. advancedvand
closed about the ‘toe. 'I'his'tends to'drawv the
upper around the corners of the toe end of the
last with the result that wrinkles are formed in
the upper which might be visible in the ?nished
shoe. An object of the invention accordingly is
to provide 7 an improved construction of end-‘
opposite sides of the toe end without any rear- _
ward wiping action of the band on the upper.
The band is thus pressed against the upper in
directions substantially normal to the contour
of the end and sidefaces of the toe of the last
so that any possibility of rearward displacement ,
of the upper is avoided as the band is applied to
the toe.

ing wipers l2 which are advanced and closed
by operating means comprising a rod or plunger
[4 and a hand lever [6 connected to said plunger
10 by a link [8. It will be understood that in the
customary use of a machine of this type the
wipers are ?rst advanced and closed about the
toe, below the plane of the shoe bottom, by move
ment of the hand lever l6 and are then raised
15 by treadle means to wipe the upper heightwise
of the toe to the edge of the insole, after which
they are further advanced and closed by move
ment of the hand lever to wipe the marginal
portion of the upper inwardly over the insole.
By use of the treadle means also the wipers may
be forced downwardly to increase their pressure
on the marginal portion of the upper and may
be raised to prevent them from dragging on the
upper when they are retracted by the hand
25 lever.
The illustrated machine also includes in its or
ganization mechanism whereby toe-clamping
means hereinafter described is applied in clamp
ing and holding engagement with the upper when
30 the wipers are advanced and closed inwardly over
the shoe bottom after the upwiping operation.
This mechanism comprises closing members or
slides 20 which are movable lengthwise of the
shoe to close the clamping means about the toe
35 end of the shoe. At their outer ends the slides 20
are pivotally connected to a crossbar 22 which is
in turn connected midway between its opposite
ends to a slide 24 having a reduced end portion on
which there is slidably mounted a crosshead
40 26. The crosshead 26 is connected to the plunger
M by mechanism fully disclosed in the above
mentioned Letters Patent No. 1,495,169, the con
struction being such that as the hand lever 16 is
swung to the right (Fig. 1) the wipers will ?rst be
45 advanced and closed relatively to the clamping
means to position their wiping edges in effective
engagement with the upper for the upwiping op
eration before the clamping means receives any
substantial closing movement, after which the
50 clamping means is closed ?rmly about the toe in
response to further swinging movement of the
hand lever in the same direction to advance and
close the wipers inwardly over the bottom of the
shoe. It will be understood that the operator is
55 thus enabled to close the wipers inwardly as far
as desired to wipe down and compact the mar
ginal portion of the upper on the bottom of the
shoe and to retract the wipers substantially to the
edge of the shoe bottom and advance them re
60 peatedly without relaxing the pressure of the
clamping means on the upper which holds the
upper conformed tightly to the contour of the last
and prevents any relaxing of the upper on the
last during the overwiping operation.

For purposes of this invention there is provided
novel toe-end-clamping means comprising the
usual ?exible supporting chain 28 and an upper
engaging member or toe band 30 which may be
made of any suitable material and, as illustrated,
is provided with a substantially rigid closed end
portion 32 having a substantially flat upper en
gaging face 33 for pressing the upper against the
toe-end face of the last and with substantially
rigid side portions 34 for pressing the upper
against the lateral faces of the last at the opposite
The toe band 36 (Fig. 3) is preferably made of
two layers 38, 39 of ?exible leather which are
cemented together and are subjected to heavy
molding pressure to conform them substantially
to the contour of the toe end of a square-toad 10
last. After the molding operation there is ce
mented or otherwise secured to the outer face of
the closed end portion 32 of the band between the
corners 36 a reinforcing strip 40 of substantially
rigid material, preferably oak-tanned sole leather. 15
Secured to the side portions 34 of the band for
wardly of the corners 36 are similar reinforcing
strips 4|. The closed end and side portions of
the toe band are thus rendered substantially rigid
with the corners 36 of the band ?exible, the rein 20
forcing strips 40, 4| serving to maintain the band
substantially in its molded shape.
The intermediate portion of the toe band 30 is
supported and controlled by mechanism substan
tially as illustrated in Patent No. 1,284,870 where 25
by the band may be adjusted relatively to the
wipers in directions lengthwise of the shoe
through the operation of a hand wheel 42, the
controlling means also permitting the band to be
moved forwardly toward the toe end face of the 30
shoe against the resistance of the usual spring
44 in response to the pull applied by the ?exible
chain 28. The closing slides 26 in their length
wise movements are wedged toward and from the
sides of the shoe to close and to open the band 35
laterally of the shoe by positive means including
rolls 46 which engage the slides in slots 48 formed
in inclined relation to the length of the slides.
The connections between the closing slides 20
and the ends of the band comprise arms 50 which 40
are mounted on the ends of the slides and are
connected by pivots 52 to the ends of the band
chain 28. The arms 50 are slotted horizontally
to embrace the ends of the slides 20 and are also
provided with vertical slots 54 to receive pins 56 45
which are secured to the ends of the slides 20.
The arms 50 are adjustably positioned in respect
to movement laterally of the shoe by means of
thumb nuts 58 which are swiveled in the ends of
the arms and are threaded on rods 60, the inner 50
ends of which are connected to the pins 56. By
turning movement of the nuts 58 the arms may be
adjusted inwardly or outwardly independently of
each other to vary and determine the pressure
applied by the band at the opposite sides of the 55
shoe. The arms 5|] are normally held from turn
ing about the pins 56 by means of rods 62 which
are swiveled on pins 64 on the outer ends of the
arms and extend through cars 66 on the slides 26.
Nuts 68 are swiveled in the ears 66 and are 60
threaded on the ends of the rods 62 for swinging
the arms 50 adjustably about the pins 56 and for
maintaining them in adjusted positions.
In the use of the machine for lasting the toe
end portions of shoes mounted upon square-toed 65
lasts the operator, by means of the thumb nuts 58,
will adjust the open position of the band 30 for
the size of shoe being operated upon and by rota
tion of the hand wheel 42 will move the band
lengthwise of the shoe to position its closed end 70
portion 32 in close relation to the toe-end face of
the last. With the toe band in adjusted position
the operator, by movement of the hand lever l6,
advances and closes the Wipers l2 about the toe
end of the last in a location below the plane of 75
2,131,837‘
the shoe bottom, after which the wipers are raised
until their wiping faces are substantially in the
7 plane of the bottom of the shoe. It will be under
stood that the wipers I2 are shaped substan
tially to conform to the contour of the toe end of
the shoe so that, as they are raised, the upper is
wiped heightwise of the last toward the edge of
the insole. Thereafter, by further movement of
the hand lever I6, the wipers H are advanced and
10 closed to wipe the marginal portion of the upper
inwardly over the insole, and substantially at the
beginning of the overwiping movement of the
wipers the slides 28 are moved lengthwise of the
shoe and are swung toward each other. As the
15 slides 20 are thus moved the upper is pressed
against the substantially straight toe-end face
of the last by the closed end portion 32 of the toe
band and the side portions of the band are swung
relatively to the closed end portion 32 toward
each other to press the upper against the lateral
faces of the last at the opposite sides of the toe
end. It will be evident that, as the toe band 30
is thus‘ advanced and closed about the toe end
of the last, the pressure of the band is applied to
the upper in directions substantially normal to
the edge contour of the toe end of the last, thus
insuring against any rearward displacement of
the upper on the last as the upper is conformed
tightly to the contour of the toe end of the last.
It will be understood that the upper is held con
formed tightly to the contour of the last by the
3
and side portions of the band substantially rigid
and the corners of the band relatively ?exible.
Having described the invention, what I claim as
new and desire to secure by Letters Patent of th
United States is:
_

toe-embracing wipers, of a toe band for clamping
an upper about the toe end of a square-toed last,
said band having a substantially rigid closed end
portion provided with a substantially straight 1O
upper engaging face and having substantially
rigid side portions connected to said closed end
portion by ?exible corners to permit the band to
be closed about the toe end of the last without
any substantial rearward wiping action of the 15
band on the upper.
2. In a lasting machine, wipers for wiping an
upper around the end of a square-teed last in
wardly over the bottom of the last, and a toe-end
embracing band for clamping the upper around 20

tom, said band being shaped to conform sub
stantially to the contour of the toe end of the
last and having its closed end portion and its side
portions reinforced to render those portions‘ of 25
the band substantially rigid and portions of the
band connecting the closed end and side portions
?exible to permit closing and opening movements
to be imparted to the band by swinging move
ments of its side portions toward and from each 30
other.‘
