ABSTRACT:
A light weight molded print hammer is provided with a pair of integrally formed and interconnected flexure members and an integrally formed rigid back-up member spaced from said flexure members, said print hammer being designed for pivotal mounting in a line priner in cooperable relationship with a solenoid and a printing position thereof, an armature carried by the molded print hammer being magnetically attracted upon energization of the solenoid to pivotally activate the rigid back-up member and to thereby translatably propel the pair of flexure members into free flight in the direction of the printing position, a metallic impact tip carried by one of the flexure members being translatably impacted into printing contact with a print media, inked ribbon and selectively positioned type character disposed in the printing position, the rigid back-up member and its spaced relationship relative to a contiguous one of the flexure members serving to absorb and to dampen the rebounding shock caused by the printing contact.
