Abstract
An improved print hammer incorporating crossed-spring support wires having a round cross section so as to render the hammer relatively flexible in a direction lateral to hammer travel during printing. The spring wires are connected between a lower body portion and a foot section. The lower body portion and foot section are designed so that the spring wires enter them substantially perpendicularly, thereby reducing stress. The foot section incorporates a pair of mounting pegs which serve to accurately locate the hammers in a hammer bank assembly. A pair of weights can be included on the spring wires in order to dampen recoil motion which occurs after the hammer impacts against a print character. The crossing point of the spring is positioned so that the springs are flexed by a constant bending moment, thereby reducing stress on the springs.
