Machine for clamping the heel portion of an upper to the corresponding portion of a form

A machine for clamping the heel portion of an upper to the corresponding portion of a form that comprises:

• support means for so supporting a shoe assembly formed of a form having an upper mounted thereon that the heel of the shoe assembly faces rearwardly;
• a clamp pad, having a pair of legs extending forwardly and divergently from a bight, so located that the bight is rearward of the heel end extremity of the shoe assembly and the legs are located outwardly of the sides of the heel portion of the shoe assembly;
• pad bight mounting and operating means operable to cause the pad bight to bear against the heel end extremity of the shoe assembly;
• and pad leg mounting and operating means operable to cause the pad legs to bear against the sides of the heel portion of the shoe assembly;
• wherein the pad leg mounting and operating means comprises:
• a plate located outwardly of each pad leg;
• means mounting each plate for inward-outward movement;
• connecting means connecting each plate to its associated pad leg;
• resilient means yieldable urging the plates, together with the pad legs, outwardly into initial plate positions such that the plates are inclined forwardly and outwardly;
• a head associated with each pad leg mounted for forward-rearward movement in intersecting relationship with its associated plate;
• means for initially retaining each head in an initial head position that is rearward of its associated plate;
• and means for yieldably urging each head forwardly of its initial head position to thereby cause the heads to engage the plates and yieldably force the plates, together with the pad legs, inwardly of said initial plate positions.
