CUTTING DIE FOR ORNAMENTING SHOE
UPPER PARTS
Stig E. Rosenberg, Brookton, Mass.
Application January 25, 1937, Serial No. 122,095 '
14 Claims.
This invention relates to cutting dies for use
in cutting an ornamental edge on shoe-upper
parts such as Vamps or wing tips. The inven
tion includes improvements in cutting and punch
5 ing dies such as that illustrated and described
in the U. S. patent to Brock, No. 1,772,335. Vamps
and wing tips for shoes customarily consist of
pieces of leather having a U-shape, the inner
edge being the onewhich shows on. the ?nished
10 shoe. Hence, the inner edge of the U is usually
ornamented before the piece is stitched to the
other pieces to form a shoe upper. This inner
edge is bell-shaped, the upper end of the bell being
toward the toe of the shoe when the vamp or wing
tip is incorporated in a shoe. In general, the
shape of the inner edge of a vamp or wing tip
varies somewhat for different sizes or widths of
shoes.
It is an object of the present invention to pro
vide a cutting die which is adjustable to cut orna
mental edges on vamps or wing tips for shoes of
dilferent sizes and of correspondingly different
Widths.
The invention also relates to dies which, in
addition to cutting an ornamental edge, also
punch
or more rows of holes near the orna
mental edge, these holes serving to add to the
ornamentation of the part. For regularity of
design, the holes in any such row are mually
3O spaced apart uniformly. In the case of Vamps,
the upper end of the bell shape formed by the
inner edge of the vamp may be widened or nar

The cutting die illustrated in. Figures 1 to 6
inclusive may comprise a base 26 on which are 20
mounted a number of blocks 22, 24, 26, 28 and 3B.
In the embodiment illustrated, the block 22 is
?xed. The blocks 24 and 28 are pivotally at
tached to the block 22 as at pivot points 32 and 34
respectively. The blocks 25 and 38 are pivotally 25
attached to the blocks 24% and 28 respectively at
their pivot points 33 and 38. Thus, while the
block 22 is immovable with respect to the base
25!, the other blocks are slidable on the base and
swing about their respective pivot points. Each
of the blocks is provided with a groove to receive
and con?ne a. portion of a ?exible blade 4!! which,
as indicated in Figure 1, is shaped to the con
rowed for shoes of different widths. Accord
ing to the invention, means may be provided to

to the upper end of the bell so as to maintain
cut on a shoe-upper part such as a wing tip or
vamp. Cooperating with the block 22 is a smaller
such spacing approximately. uniform when the
?xed block 52, these blocks alternating the mid—
portion of the blade 49. Adjacent to this mid
width of the upper end of the bell is increased or
diminished.

portion of the blade are two portions which are
supported and con?ned by the blocks 24 and 28
respectively. The end portions of the blade 40
are supported and con?ned by the blocks 26 and
36 respectively. Thus, the shape of the blade,
and hence the shape of the cut made by the blade,
is determined by the positions of the movable
blocks on the base, the natural shape of the blade
being modi?ed by movements of the movable
blocks.

or the other, the block 92 is correspondingly

Each of the blocks is preferably provided with
a stripper plate I88, these plates being supported 15
in the usual manner by posts I02 having their
lower ends resting on springs I04 so that the
plates may give when pressure is brought to bear
against the work from above.
Figures 8 to 11 inclusive illustrate a modi?ed 20
form of the invention particularly designed for
cutting ornamental edges on Vamps. These cuts
are bell-shaped and vary in width according to

wing tips are superimposed so that the outlines
of the ornamental edges can be directly com
pared. As shown, a wing tip 44 for a relatively

ward or from each other. Each block has a slot
H8 in which rides a stationary screw I25) to limit 30
These two'changes in the contour are
30' made possible by the arrangement of the movable
blocks shown in Figure 1.
Any suitable means
for adjusting the positions of the movable blocks
may be employed. As shown, a pair of toggle
arms 50 and 52 are employed for adjustably mov
35 ing the blocks 24 and 28 in their pivots. A second
pair of toggle arms 54 and 56 are employed for
adjustably moving the blocks 26 and 3B.
The
arms 50 and 52 are pivotally attached to a nut
50 through which is threaded a portion 62 of a
40 rotatable shaft. Thearms 54 and>56 are pivotal
. ly attached to a nut 66 through which is thread
ed a portion 68 of the same shaft. This shaft
may be rotated by a knurled ?nger-piece ‘I0 and
may be held against axial movement as by a
notched plate ‘I2 which ?ts between a ?ange ‘I4
and the forward end of the ?nger-piece 10. In
' order to obtain the desired relative rates of ad
justive movement of the various pairs of blocks,
the screw thread of the shaft portion 62 is differ
ent from the screw thread of the shaft portion
68, the former having a smaller pitch. Thus,
as the shaft is rotated to move the blocks, the nut
69 advances more slowly than the nut 66.‘ The
rate of adjustive movement of the various blocks
; is also determined by the lengths of the toggle
arms, the arms 50 and 52 being shorter than the
arms 54 and 56.
These various members’ are so
designed that, as the blocks 24 and, 28 swing
toward each other, the blocks 26 and 30 swing
away from each other, these relative movements
producing the outlines shown in Figure 7. Figure
1 shows the movable blocks in position to cut a
wing tip for a shoe of large size. Figure 2 shows
the parts in position for cutting a wing tip of
smaller size. Theblocks 2B and 30 may be pro
vided with suitable slots 18 and 80 in which ride
screws 82 and 84 respectively which limit the
movement of the blocks in either direction. The
screws 82 and 84 are mounted in the base 20.
In addition to cutting an ornamental edge on
the wing tip by means of the knife 40, it may be
desired to ornament the marginal portion of the
wing tip adjacent to the edge by a pattern of
punched holes. To this end, a suitable number
of punches 80 may be mounted on the various
guided by a guide rail H6 so that they slide to
the travel of the blocks. In addition to the
blocks H2 and H4 which slide toward and from
each other, pivotally attached blocks I22 and I24
are provided, the block I22 being pivoted to the
block IIZ as at I25, the block I 24 being pivoted 35
to the block II4 as at I28. Additional pivoted
blocks I30 and I32 may also be provided, these
blocks being pivoted respectivelyyto the blocks
' I22 and I24 at the points I34 and I36. Each of
the six blocks thus far described is provided with 40
a slot in which a portion of a ?exible knife I46
is suppo-rted'and con?ned, the adjusted shape of
the knife being determined by the positions of V
the several blocks.
The blocks are adjustably
moved by any convenient mechanism such‘ as a 45
toggle device I42 operated by a threaded portion
‘ I44 of the shaft I46 to move the blocks H2 and
I I4 toward and away from each other. Another
toggle device I50 is operated by a threaded por
tion I52 of the shaft I 46 to swing'the blocks I22 50
and I24 about their respective pivots. The
swinging movements of the blocks I22 and I24
also cause swinging movements of the blocks I39
and I32 which are pivotally attached thereto, the
movement of the latter. blocks being influenced 55
by the knife I43] which extends from each bloc
to the next adjacent block and which has a con
siderable degree of stiffness. A pair of abutment
elements I56 and I58 are provided to limit swing
ing movement of the blocks I30 and I32 in one 60'
direction.

to an inoperative position. Figure 10 illustrates
the punch in its operative position ready for use.
a Figure
1 shows the punch in its idle position.
Figures 12 to 14 inclusive illustrate mechanism
by which the uniformity of spacing of the
punches can be better preserved during the ad
justive movements of the knife-supporting
blocks. Figure 12 illustrates a die having a base
10 HQ on which are slidably mounted a pair of
blocks I12 and I74, these blocks being movable
toward and from each other to vary the width of
the forward portion of the bell-shaped cut made
by a knife I'IB which is supported by the blocks
15 E12 and I14, other portions of the knife being
supported and con?ned by swingable blocks I85
and I82, the latter being hinged respectively to
the blocks I12 and I14 as at I84 and I86.
A
number of the punches I90 at the mid-portion of
20 the ornamental edge are individually mounted
on lever arms I92, M4 and I96 on the block I12,
and 260, 202 and 204 on the block I14. It is ob
vious that, while three such lever arms are shown
on each of the blocks I12 and I14, a greater
25 or lesser number of such arms may be employed
as found convenient or necessary.
The arms
I92, I94 and I96 are pivoted individually as at
2!!! on the block I12. The arms 200, 202 and
264 are likewise pivoted at the points 2 I6 on the
30 block H4.
The arms in each of these groups are
If desired, a suitable scale 25!] may be mounted
on the base I'I? to cooperate with an index 252
on one of the blocks to indicate the size of shoe
corresponding to the particular adjustment of
the blocks of the die.
_
It is evident that Various modi?cations and
changes may be made in the details of structure
shown and described without departing from the
spirit or scope of the invention as de?ned in the
following claims.
I claim:—
1. A cutting die comprising a base, a blade
having the approximate shape of the cut to be
made, a series of blocks on the upper face of
said base supporting and con?ning said blade 15
to determine the shape thereof, means maintain
ing said blocks against said face, said blocks in
cluding a pair slidable on said face and con?ning
portions of said blade symmetrical with respect
to its mid-point, said blocks also including a sec
ond pair slidable on said face and con?ning por
tions of said blade adjacent respectively to said
symmetrical portions, and means for adjustably
moving said blocks on said base.
2. A cutting die comprising a base, a blade
having the approximate shape of the cut to be
made, a series of blocks on the upper face of
said base supporting and con?ning said blade to
determine the shape thereof, means maintaining
said blocks against said face, said blocks includ 30
connected by plates 22!! and 222 respectively.
ing a pair movable on said base and con?ning
The plate 220 is attached to the three arms of
its group at the pivot points 224, 226 and 228 re
spectively. In like manner, the plate 22 is at
35 tached to the arms of its group at the points
portions of said blade symmetrical with respect
239, 232 and 234 respectively. It is thus evident
that, if any one arm of either group is rocked
about its pivot, the connecting plate will cause
40
45
the other two arms of the group to rock accord
ingly, but the actual amount of rocking move
ment of each arm will differ since the points of
attachment of the several arms to the plate are
at diiferent distances from the respective rocking
axes 2H3 or 2I6.
The inner two arms I96 and
260 are notched at their ends as at 240 and 242.
Within these notches are a pair of lugs 244 and
246 respectively.
When the blocks I12 and I14,
carrying the groups of arms, are adjustably
50 moved away from each other, the arms: of one
group move away from the arms of the other
group. Since the lugs 244 and 246 catch in the
notches 240 and 242, the arms I96 and 200 are
forced to rock on their respective pivots. This
55 rocking movement of these arms counteracts
the tendency to increase the spacing between
the punches I9Il on these arms. Owing to the
connecting plates 22!) and 222, the other arms of
each group are also forced to rock on their
60 pivots but to lesser extents, these rocking move
ments also tending to counteract partially the
spread effect of the movement of the blocks on
which the arms are mounted. Thus the six
punches I98, which are connected on the rock
65 arms, are gradually spread apart so that the
spacing between the successive punches carried
by these arms is maintained approximately uni
form, that is, excessive inequality of spacing is
avoided, that being true for any position of ad
70 justment of the blocks I12 and I14.
“While the rock arms are shown in connection
with a single pair of swinging blocks I80 and I82,
it is evident that the same features could be em
ployed with swinging blocks such as are illus
trated in Figure 8.
