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.

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. :11 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 A female mold for shaping counter-sti?ener ridges will not be entirely withdrawn from their cooperating grooves but will form a substantially 40 sinuous crevice at the inner ends of the recesses la,—2a of substantial amplitude, thereby posi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. These number, 45 tion, or in Figs. 25 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. 10.
