The patent discloses a method of producing
shoes having so-called close shanks, that is shoes
having a transversely convex bottom in which
the edges of the shank portion of the sole lie close
by cause said edges to separate from said upper.
In carrying out the method, use is made of a
sole having in its shank portionl a longitudinal
gouge and a flap or tongue which is the counter
part of the gouge and is hinged to the sole along

gitudinally adjustable in a slot I1 (Fig. 3) in a
block I9 which is adjustable toward and from the
rolls and may be so adjusted by turning a hand
wheel 2l located at the front of the machine.
The block i9 (Figs. 1, 8) is adjustably mounted ,¿
in a table 23 which is pivotally supported upon
the upper ends of four substantially upright par
allel links two of which are indicated at 25.
Referring to the accompanying drawings:

heel gage 33 are pivoted about Vthe smooth po-r
tion of a similar screw 39 the lower reduced end
30 of which is threaded into a threaded hole 4| in
another ear of the block I9. 'I‘he shank gages
29, 30 have respectively rear extensions 43, v¿l5
which terminate in interengaging toothed seg
ments 41, 49, so that the shank gages'are com
pelled to swing equally‘in opposite directions. The
heel gages 3|, 33 have similar extensions which
lie directly below the extensions 43, 45 ‘and termi
nate in interengaging 'toothed segments which
lie directly below the segments 43, »45. The ex
tension 43 of thefshank gage ‘.29 is connected by
a link 5| to'one end of a whillletree 53 which `is
pivoted at its middle at 55 to one end of a short
link 51. A tension spring 6| connecting the pivot
‘63 of the link 5| with a short arm on the shank
gage 29 lnormally »holds the shank gages 29, 3!)
45 in the open position shown.
A link’65 is: pivoted ‘
at one end to the extension of the heel gage 33
and at the other end at 61 to the other end of the
whiiîletree 53; and a tension spring 69, connected
at one end to the pivot S1 and at the other end
to an arm on the gage-33 normally holds the gages
3|, 33 in the open position shown. The short
link 51 at its right-hand end is pivoted -about a
horizontal pin 1| carried by the arms of a fork
at the upper end of the upright arm of a bell
55 crank lever 13 pivoted at 15 to a bar 11. The
inner end of this bar is rabbeted and fastened
tothe block I9 by cap-screws 19. To the sub
stantially horizontal arm of the bell-crank lever
13 is fastened‘the upper end of ~a two-part chain
60 8| the'lower end of which is fastened to the
treadle 21. The two parts of‘the chain are-con
nected by a tension spring >85. When the treadle
is depressed it exerts a pull Yon the chain and
also pulls down va link 81 having a. slot 88 in its
65 upper end in which is .received a pin 89. The ñrst
part of the ‘downward movement of the treadle
swings the bell-crank lever ‘to pull the link 51 to
the right and close the two pairs of gages on the
sole, thereby centering the sole. All this takes

which is held in engagement by a tension spring
99 with one or another of the teeth 91 of a rack
formed on the right-hand end of the bar 11, the 15
spring being attached at one end to the pawl 93
and at the other to the bell-crank lever 13. When
the treadle is depressed, and the bell-crank lever
13 is swung clockwise, as viewed in Fig. l, the
pairs of edge gages are closed upon the sole and 20
The pawl 93,
however, prevents these springs from returning
.the parts to the positions shown in which the
gages are open.
It is necessary to release the
pawl before the completion of a cycle of opera
25
tions of the machine so that the gages will once
more be open >to receive the next sole. To this
end use is made of the swinging to the left of the
right-'hand one of the links 25 upon the upper
ends of which the table 23 is pivoted. An exten 30
sion or tail is >provided on the lower end of the
right-hand link 25 which appears in Fig. 1, and to
it is pivoted at IBI the lower- end of a Vtwo-part
push rod |03 the two parts of which are adjust
ably fastened together by two screw-and-slot 35
connections »I E5 so that the length of the rod may
be varied. Upward movement of the push rod |03
actuates a slide member to release the pawl 93
and thereby permit the two pairs of gages to open.
Referring to Figs. 6 and 9, this slide member or
trip |01 has a slot |59 in its left-hand end to re
ceive the pin 15 about which the bell-crank lever
13 is pivoted, and a second slot ||| in its right
hand end to receive the smooth portion of the
stem of a screw H3 which extends through the 45
slot and yis threaded into that part of the bar 11
on which the teeth 91 are formed. The slide
member or trip has formed upon it a small pro
jection IE5 which is engaged by the topÁ of the
push Vrod |33 when .the rod is moved up, such 50
engagement causing the trip |51 to slide to the
right so as to push the pawl 93 away from the
teeth 51 and permit the bell-crank lever 13 and
the pawl 93 to return to the positions shown. The
construction and arrangement of parts is such
that the pawl 93 holds the two pairs of gages in
contact with >the sole until the rolls II, I3 have
firmly gripped the sole, after which the pawl is
pushed out of engagement with the teeth 91 and
returns to the position shown. At the same time 60
the tension springs 6|, 69 open the two pairs of
gages to position them to receive another sole.
Referring now to Fig. 2, the gouge 250 and flap
or tongue 38D are produced by distorting the
shank portion of the sole and feeding it past a 65
stationary straight edged knife in such manner
that the knife enters one face of the sole at the
line ||1 and emerges from it lat the line IIS, the
knife in forming the gouge cutting along the line
|2|, thereby leaving the tongue l3BE! hinged Vto 70
the sole along one edge of the gouge in a‘narrow
locality parallel to the line |_2|. To this end, the
lower roll || (Fig. '1) is provided with spaced
toothed disks |23 (Fig. '1), the two disks at each
end of the roll being of comparatively large di
2,125,959

diameter so that in effect a depression or sort
I3. As soon as the rolls have properly gripped
the sole, the table 23 returns to the position
shown. During the forward movement of the
table, when the links 25 swing to the left, the
of matrix is formed by their peripheries; and
into this matrix or depression the shank portion
of the sole |03 isbent by a suitably shaped pro
jection or patrix §25 on the other roll I3.
The
right-hand end edge |21 of the knife 2G is out
side of the sole and is cutting along the. line |2|
of Fig. 2. The left-hand` end of the edge of the
knife is within the sole so that, when the cut is
finished, the flap or tongue ’300 will remain at-`
tached to theï sole. The ‘stem of the knife 23
` (Fig. 3) Vextends obliquely to the axes of the
rolls il, I3 and is adjustably fastened to a block
|29 by cap screws |3| which> pass through slots
in the knife stemvand‘ are threaded into‘ the
block. i The block has in its under side a groove
which is parallel to the axes of the rolls li, i3;
and in this groove is received the upper part of
` a key |33 the lower part of which is received in
a groove |35 in a wide bar |31 fastened by cap
screws, one of which'is shown at |39, to thev
frame of the machine. A clamping screw Mi
extends up through an enlarged hole |43 in
the bar, through a hole in the key |33Vand is
threaded into the lower side ofthe block |23.
The head of this clamping screw |4| appears
in Fig. 1. With this construction, after the cap
screws |3| have been loosened, the knife may be
30 adjusted obliquely to bring its cutting edge |21
into the desired position back of the bite of the
rolls; and, after the clamping screw Mi has been
loosened, the knife may be adjusted in a' path
to ensure that the sole shall be fed out from be
tween the ro-lls after the gouge and the tongue
have been produced, the upper roll i3 is provided
with two ears, one of which is shown at |55 in 25
Fig. 4. These ears engage the top of the sole
and hold it against the lower roll.
Although the invention has been set forth as
embodied in a particular machine, it should be
understood that the invention is not limited in 305
the scope of its application to the particular ma
chine which has been shown and described.
Having described my invention, what I claim
as new and desire to secure by Letters Patent
of the United States, is:
1. A machine for forming upon a piece of sheet
material a gouge and a tongue which is hinged to
the material along one edge of the gouge having,
in combination, a pair of feed rolls and a knife to
has at itsv forward end a hook to engage the point
at one end of the edge |21 of the knife 23. As
4d, soon as the knife has been replaced and properly
adjusted, this gage is swung out of the way. It
may be noted (Fig. 3) that the cutting edge of
the knife and one edge of the stem of the knife
intersect at an acute angle to form a point at
one end of the cutting edge of the knife.
In order to» assist in holding the sole up against
the patrix roll I3, a series of spring-pressed nn
gers |131 (six being shown) are provided, the
which the rolls feed the material, said rolls being
Ashaped to form a bulge in the material and to
feed the bulged portion to the knife in such man
4.o
ner that one end of the edge of the knife enters
one face of the material, remains in the material
for an interval and then emerges from said face, 45
and the other end of the edge of the knife re
mains at all times outside of the material.
2. A machine for forming upon a piece of sheet

material a gouge and a tongue which is hinged to
between the toothed disks |23 of the lower roll.
'I'hese fingers are pivoted about a stationary hor
izontal rod |49 and have downwardly extending
stems which are normally held against a sta
tionary rod |5| (Fig. 1) by tension springs one
of which is shown at |53. When the sole is be
ing operated upon (Fig. 5) these fingers press
the sole upwardly against the roll I3.
The operation of the machine is as follows.
With the parts of the machine in the positions of
rest shown in Figs. 1 and 3, the operator thrusts
a sole lßll through the gap between the rolls until
the material along one edge of the gouge having,
in combination, a pair of feed rolls, and a
straight-edged knife to which the rolls feed the
material, said rolls being shaped to form a bulge
in the material and to feed the bulged portion to
the knife in such manner that one end of the
edge of the knife enters one face of the material,
remains in the material for an interval and then
emerges from said face, and the other end of the
edge of the knife remains at all times outside of
the material.

3. A machine for forming upon a piece of sheet
material a gouge and a tongue which is hinged to
the material along one edge of the gouge hav
ing, in combination, a pair of feed rolls, and a
straight-edged knife, said knife having a cutting
edge which is substantially parallel to the axes of
the rolls and a stem which extends obliquely to
the cutting edge, one edge of the stem enclosing
with the cutting edge of the knife an acute angle
to form a point at one end of said cutting edge,
said rolls being shaped to form a bulge in the
piece and feed it to the knife in such manner
that the point at one end of the cutting edge
enters one face of the material, remains in the
material for an interval and then emerges there
' its heel end contacts with the end gage i5.
He
thereupon depresses and then releases the treadle
21. The ñrst part of the downward movement
i of the treadle swings the bell-crank lever 13
65 clockwise thereby causing the shank gages 23, 3|]
and the heel gages 3|, 33 to close upon the sole.
During this downward movement, the tooth of
the pawl 93 runs over the teeth 91 of the station
ary rack and holds the gages in closed` position.
The latter part of the downward movement of
the treadle 21, through the link 81, starts the
machine. The links 25 swing to the left, as
viewed in Fig. 1, to move the table 23 to the left
75 in timed relation to the rotation of the rolls and
70
91 and permitting the pairs of gages to be opened
once more by the springs 6|, 69. It will be noted,
by reference to Fig. '7, that the point at one end of
the edge of the knife |21 enters one face of the
sole while said sole is distorted, remains in the 115i
sole for an interval and then emerges from the
sole, but that the other end of the edge lof the
knife remains at all times entirely outside of the
sole. The result is the production of the gouge
20G (Fig. 2) and the tongue 30|] which is hinged 20'
to the sole along one edge of the gouge. In order
