The present invention relates to the manufac
ture of counters and in one aspect consists in
a novel machine for skiving and slashing counter
blanks preparatory to molding them. In an
5 other aspect it consists in an automatically oper
ating slashing mechanism Which may be em
ployed as an independent unit or as an attach
ment or auxiliary mechanism for a skiving ma
In making certain types of shoes, of which
stitch-downs are one example, the shoe manu
facturers require counters having outwardly
directed flanges as distinguished from the in
turned ñanges which are found in counters in
1 Ul tended for shoes of other types. In preparing a
counter blank for molding an outturned flange
therein it has been the practice to slash a por
tion of the lower margin since> otherwise this
must be elongated in the molding operation. The
20 slashes permit sections of the margin to fan out
and lie flat without distortion of the upstanding
walls of the counter thus facilitating the mold
ing operation and improving the molded counter.
lowing description of a preferred embodiment
thereof selected for purposes of illustration. and
shown in the accompanying drawings in which,
Fig. l is a cross-sectional View on the plane I--l
of Fig. 2 showing the operative instrumentalities I
of the machine, the frame being omitted for the
sake of clearness,
Fig. 2 is a View of the machine in elevation as
seen from the right-hand end in Fig. 1,
Fig. 3 is a plan view partially in section, of the
mechanism shown in Fig. l,
Fig. 4 is a view in perspective of the slashing
rolls, and
Fig. 5 is a view in perspective of a slashed
counter blank.
As herein shown the slashing mechanism is
incorporated in a counter skiving machine of
commercial construction, and only so much of
that machine is shown as is necessary for an
understanding of the present invention.
Journaled in the main frame of the machine
is a pair of transverse Shaftslß and l2 arranged
one above the other and carrying respectively a
matrix cavity roll ll and a toothed feed roll I3.
Prior to my invention counters have been
25 slashed as a distinct operation either by hand or ' A work table I4 is located in position to direct suc- .
by the aid of a slashing machine to which the cessive counter blanks into the bite of the rolls
counter blanks have been presented successively
'by an operator. An object of the present inven
tion is to provide an automatically acting slash
30 ing machine to which counter blanks may be fed
mechanically from a magazine or other source of
supply and by which the slashing operation is
effected automatically, accurately and at high
speed, without making any considerable demands
35 upon the skill and judgment of an operator.
In slashing a counter blank it is undesirable
to carry the slashing into the straight forward
portions of the counter flange since the slashes
have no useful function in those portions of the
40 ñange which are not to be given an arcuate shape
and, if present, would tend objectionably to
weaken the flange. Accordingly, an important
feature of the present invention consists in a
machine constructed and arranged to confine the
45 slashing operation to a zone of predetermined
length and location. The slashing operation is
and a skiving knife l5 is adjustably mounted
on a carriage I6 directly behind the rolls. The
carriage i6 is in turn mounted upon an adjusta
ble support Il. As the flat counter blanks are .30
fed between the rolls, the feed roll I3 forces the
center port-ion of the counter into the cavity of
the matrix roll I I with the result that the skiving
knife l5 bevels the entire margin of the counter
blank as the latter is advanced by the action .‘ ,
of the rolls.
Referring to Fig. 5, the counter blank there
illustrated has a thick, unskived center portion 90
defined by a bevelled marginal portion 9i, as a
result of its passage through the matrix roll »l
mechanism just described. As the skived counter
blank leaves the knife l5, it is advanced across
a guide plate I8 until it is engaged by feed rollers
which carry it to the slashing mechanism.
An upright portion 2Q of the machine frame is
shown in Figs. 2 and 3 as providing bearings for
effected upon the counter blank as the latter is
a transverse shaft 2l carrying at one end a
passed in a flat condition through the machine,
sprocket Wheel 22 which is driven by a sprocket
and, as herein shown, the desired results are
50 achieved by providing mechanism for rendering
chain 23 through a sprocket wheel i9 on the end
of the feed roll shaft i2. The shaft 2| carries a
the slashing knives inoperative during a pre
determined portion of the feeding movement of
the blank.
These and other features of the invention will
be best understood and appreciated from the fol
pinion 2li meshing with an idle pinion 25 mount
ed on a stub shaft directly above it, and in turn
driving a pinion 26 which is fast on a sleeve 2T
mounted upon a transverse shaft 28 which is
journaled in the frame 2U. Fast upon the sleeve K
21.1's an anvil roll 29 which cooperates with the
slashing roll 30 in feeding and slashing the
counter blank.
The slashing roll 30 is equipped with a series
of spaced axially arranged blades 35 which ex
tend as a series completely about its circumfer
ence. The slashing blades are aligned circum
ferentially; that is to say, they are of equal length
and their ends lie in the same transverse planes.
10 The slashing roll is secured to a sleeve 3l which is
journaled upon a transverse shaft 32 and pro
vided with a pinion 33 meshing with the pinion
26 of the anvil roll sleeve already mentioned.
The slashing roll shaft 32 is mounted for bodily
15 vertical movement in vertical ways formed in the
upper part of the frame 20. It is connected at
each end to a tension spring 34, which normally
tends to lift the shaft 32 and the slashing roll into
inoperative relation with the anvil roll 29. The
shaft 32 is forced positively downwardly into op
erative position by cam-actuated mechanism
which will now be described. In addition to the
pinion 24, the shaft 2| carries a small pinion 48
and this is arranged to mesh with an idle pinion
4| journaled upon a stub shaft projecting out
wardly from the frame 20. The pinion 4| in turn
meshes with a pinion 42 to which is adjustably
secured a cam 43. The pinion 42 and its cam
are journaled upon the outer end of the shaft
30 28 which also carries the anvil roll 29. The cam
43 has a bolt and slot connection with the pinion
42 permitting adjustment of the cam to regulate
its timing. 'I'he clamping bolt 44 of this connec
tion is shown in Figs. 2 and 3.
smooth-faced roll of soft steel or brass and that
the slashing knives 35 may embed themselves in
the face of the anvil roll in making clean slash
ing cuts 92 in the margin of the counter. The
anvil roll is shouldered or relieved to afford clear
ance beyond the zone of the slashing blades 35
for the thick unskived center portion 90 of the
counter blank.
The slashing roll 30 is adjustably
secured to its sleeve 3| by a set screw as shown in
Fig. 4 and when this is loosened the roll 30 may
be turned upon the sleeve to bring the slashing
blades into any 'desired relation with respect to
the counter blank.
The operation of the machine will be clear
from the foregoing description, but may be
briefly summarized as follows. The flat and un
skived counter blanks are placed upon the work
table I4 and advanced one by one by the forward
movement of a feed slide properly timed to meet
the matrix roll || where the periphery thereof is
shaped to force the blank downwardly for skiving
the advancing end of the blank. The blank
passes beneath the matrix roll and comes out
upon the guide plate I8 with its margin 9| sklved
as indicated in Fig. 5. As the blank passes out of
the feeding range of the rolls || and |3 it is ad
vanced until its straight marginal portion is
engaged between the anvil roll 29 and the slash
ing roll 30. When the counter blank first
reaches these rolls the slashing roll 30 merely 30
rests upon it with a feeding pressure so that the
forward movement of the blank is continued
without any slashing taking place. When, how
ever, the blank has been advanced to the proper

its lower end partially to encircle the shaft 32. throughout a Zone determined by the length of
In Figs. 1 and 2, the cam roller 46 is shown as
45 being thrown outwardly by the high portion of
the cam 43, swinging the cam lever 45, depressing
the plungers 49 and consequently holding the
shaft 32 and the slashing roll 3|) in their lowered
or operative position in which the knives 35 of
50 the roll 30 are effective to slash and feed the
counter blank which is passing between it and the
anvil roll 29. When the cam roller 46 passes off
from the high part of the cam 43 the springs 34
are free to release the shaft 32 so that the slash
55 ing blades 35 no longer slash the counter blank
but merely engage it as feeding spurs.
A pair of feed rolls 5| and 52 are provided at
the rear end cf the guide plate |8 as already inti
mated. The lower of these feed rolls is mounted
60 upon a shaft which is freely rotatable and is
preferably a rubber roll. The upper feed roll 5|
is mounted upon a shaft 53 having a pinion 54
at its outer end which meshes with an interme
diate idle pinion 55 and that in turn meshes with
the pinion 33 which is carried by the sleeve 3| of
the slashing roll. In passing through the feed
rolls 5| and 52 to the slashing roll 30 the counter
blank is conducted through a narrow guide pas
the cam 43, whereupon the cam lever 45 is re
leased and the counter blank fed out from be
neath the slashing roll without having any fur
ther slashing cuts made in it.
Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
ent of the United States is,
1. A counter skiving and slashing machine
comprising matrix roll skiving mechanism, a roll
having slashing blades mounted thereon and a
cooperating anvil roll, a common actuating means
for driving the matrix roll and the slashing roll,
and mechanism for interrupting the effective op
eration of the slashing roll independently of the
skiving mechanism thereby limiting the slashing
operation to a portion only of the sklved area of
the counter.
'2. A machine for slashing counters, comprising
a flat faced anvil roll, a cooperating roll having a
series of straight slashing blades set therein, op
erating means for the rolls, and automatic mech
anism for throwing them into slashing relation 65
for a predetermined interval during the passage
of a counter between them.
3. A machine for slashing counters, comprising
sage 60 and so prevented from becoming mis- - a flat faced anvil roll, a slashing roll having a
placed in the machine.
The intermediate feed
roll 5| and the pinion 55 are enclosed beneath a
cover plate 36 and this is supplemented by a
hinged guard 38 which extends forwardly beside
the slashing roll 30.
It will be understood that the anvil roll 29 is a
series of straight slashing blades set therein, 70
means for driving said rolls to feed a counter be
tween them, and automatic mechanism for forc
ing said rolls into slashing relation after a coun
ter blank has been advanced for a portion of its
length between them.
4. A machine for slashing counters, including
in its structure a pair of shafts arranged in paral
lel relation, elongated sleeves rotatably mounted
on both shafts and geared together, a flat faced
Ul anvil roll mounted on one of said sleeves, a slash
ing roll mounted on the other sleeve and having a
series of straight slashing blades set therein, and
automatic cam controlled means for positioning
one of said shafts to bring said rolls into operat
ing position for a predetermined time interval.
5. A machine for slashing fiat skived counter
blanks, including in its structure a roll having an
aligned series of radial slashing knives set in its
periphery, and a flat faced anvil roll cooperating
therewith, one of said rolls being relieved beyond
the ends oi the slashing knives to accommodate
an unskived portion of a counter blank passing
between the rolls.
6. A machine for slashing counter blanks, in
cluding its structure a driven member having
thereon a rotatably adjustable roll provided with
a series of spaced slashing blades, means for hold
ing the roll in diiïerent positions of rotary adjust 5
ment, and adjustable means for supporting said
driven member in slashing position during a pre
determined interval.
7. A machine for slashing counter blanks, in
cluding in its structure a positively driven sleeve 10
having thereon an angularly adjustable slashing
roll provided with a series of spaced slashing
blades, an anvil roll, and cam controlled mecha
nism for holding the sleeve and slashing roll in
slashing relation to the anvil roll during a pre 15
determined interval.
