ABSTRACT:
An improved pushrod for an impact printer or the like wherein the pushrod wire has a tip member at each end thereof, the outer ends of the tip members having a seat-forming, preferably conical, recess therein communicating with an underlying undercut cavity, a molded impact button being seated in the recess and filling the undercut cavity, the impact button having an outwardly projecting surface which is preferably flat. In a preferred embodiment the axial bore in the shank of the tip member communicates with the annular cavity and the undersurface of the impact button has a centrally disposed recess therein. The shanks of the tip members are preferably swaged to the pushrod wires at three or more angularly equal locations about the periphery of the shanks, the ends of the pushrod wires being roughened by grit blasting.
