The counter-stiffener blank B is usually formed
of leather or ?bre cut to desired shape, and the
operator bends it into the general horse-shoe
shape (Fig. 3) prior to insertion of the blank in
the recess la‘, 2a, which operation usually results
in a sharp bend B’ at the center of the blank;
and this portion B’ often enters into the V-shaped
crevice to, 2c, of the open mold so that the sub
sequent closing of the jaws drags into the crevice
and traps therein a part of the bent portion B’

of the blank which will be thus pinched or in
I claim:
1. A mold for shaping counter-sti?ener blanks
comprising a pair of opposed recessed jaws mov
able towards or from each other and provided
with portions adapted to prevent a blank being
caught in the crevice between the jaws during
the shaping operation; the said portions main
taining the lateral adjustment of the jaws when
closed.
2. A mold for shaping counter-stiffener blanks l0
comprising a pair of opposed recessed jaws mov
jured causing the formation of aridge along the
bend of the ?nished blank, which ridge not only
detracts from the appearance and sale of the
15 counter, but is a potential source of weakness in.
that the ridge is actually formed of ?bres of the
blank which have been dislodged from their
normal place in the blank, removing their anchor
age, the dislodged ?bres being crushed and
20 broken by the molds in the act of closing. This
able towards or from each other and provided at
the rear ends of the recesses with overlapping
and interlocking portions which when the mold is
opened will prevent a blank being pinched dur 15
ing the shaping operation.
3. A female mold for shaping counter-stiffener
blanks or the like comprising a pair of opposed
recessed jaws movable towards or from each
ridge is actually a rupture extending from the
top to bottom of the ?nished counter at the center
of the heel, and often causes the counter-sti?ener
to break at this point.

interlocking portions adapted to prevent the
ates this objection by replacing the usual
straight-line crevice formed by surfaces lo, 20, in
blank from entering the crevice between the op
posed iaces of the jaws during all shaping op
erations.
ii. A mold for shaping counter-stiffener blanks
comprising a pair of opposed. recessed jaws mov
Figs. l—2 with a series of interlocking serrations
formed on the opposed faces of the jaws extend
30 ing from the inner ends of the recesses la, 2a to
the inner or pintle ends of the jaws, said serra
tions being in the form of ridges lac, 2x and
grooves iy, 2y as shown in Figs. 5-7 inclusive,
the ridges on one jaw interlocking in the grooves
in the opposite jaw, and the ridges and grooves
being of su?icient length and depth that when
the jaws are opened to receive the blank B the
35
able towards or from each other, the opposed
faces of the jaws adjacent the recesses being
provided with overlapping portions forming a 30
substantially sinuous crevice between the inner
ends of the recesses in the jaws when the mold
is open, and preventing the blank being pinched
during the shaping operations.

5. A female mold for shaping counter-sti?ener
ridges will not be entirely withdrawn from their
cooperating grooves but will form a substantially
40
sinuous crevice at the inner ends of the recesses
la,—2a of substantial amplitude, thereby posi
tively preventing the bent end B’ of the blank
from entering said crevice.

ridges lzt, 2x may be one or more in
and may also be of angular cross-sec
may be rounded convolutions as shown
5-7 inclusive, or may be of any other
desired cross-section which would make the ser
rations of the jaws interlocking. As the ridges
lac, 20: in one jaw interlock into corresponding
50 grooves 2y, ly in the opposite jaw the ridges
of both jaws cross the axis of the pintle 3 and
thus make an interlocking ?t into recesses in the
blanks or the like comprising a pair of opposed
recessed jaws movable towards or from each
other, the opposed faces of the jaws adjacent
the recesses being provided with interlocking
overlapping portions forming a substantially sin
uous crevice of substantial amplitude between
the opposed faces of the jaws when the mold is
open, thereby retaining the blank within the con
?nes of the recesses.
6. A mold for shaping counter-stiffener blanks
or the like comprising a pair of opposed recessed
jaws movable towards or from each other, the
opposed faces of the jaws beyond the inner ends
of recesses being provided with alternating ridges
and grooves interengaging when the mold is
opened to prevent pinching of a blank entered
between the jaws preparatory to shaping same.
'7. A female mold for shaping counter-stiffener
opposite jaws, thereby dispensing with the
straight-line crevice between surfaces 50, 2c,
55
shown in Figs. 1-2, and forming an effective
blanks or the like comprising a pair of opposed
recessed jaws movable towards or from each
barrier preventing any portion of the blank B
from passing beyond the con?nes of the mold
cavity la—-2a. Therefore no unwarranted dis
60 placement or distortion of the ?bers of the blank
alternating ridges and grooves interlocking while
B can be effected at any point in the mold.
Moreover in the usual mold construction shown
in Figs. l-2 the two jaws are kept in lateral
adjustment only by the pintle 3 with respect to
the ?ange B2 (Fig. 3) formed by the usual slide
65
(not shown) which passes over the face of the
mold, whereas in my construction the inter
locking serrations not only permit movement of
the mold jaws toward and away from each other,
but same also hold the jaws in proper lateral ad
70 justment so that the slide of the machine which
forms the ?ange B2 (Fig. 3) around the lower
edge of the ?nished sti?ener will always form
flanges of unvarying and uniform thickness,
75 which is a very desirable result.
other, the opposed faces of the jaws beyond
the inner ends of recesses being provided with
the mold is opened to form a substantially sinu
ous crevice of substantial amplitude between the
opposed faces of the jaws retaining the blank
within the confines of the recesses.
8. In a mold as set forth in claim '7, the inter
locking ridges and grooves maintaining the jaws
in ?xed lateral adjustment when the jaws are
closed.
9. A mold for shaping counter-stiffener blanks
or the like comprising a pair of pivoted recessed
jaws, the jaws being provided adjacent their
pivot with interengaging and interlocking Dro
jections which when the mold is opened will pre
vent a blank being pinched between the jaws
at the inner ends of the recesses during the shap
ing operation.
