ABSTRACT:
A half-herringbone support for the comb hammers of a dot matrix line printer is disclosed. The half-herringbone support is generally flat and includes an elongate base and a series of parallel tines integrally formed with said base and projecting obliquely outwardly from one edge of the base. The number of half-herringbone tines is equal to the number of hammers. The base of the half-herringbone support is affixed to the base of the hammer support on the side containing the hammer anvils (balls). The outer tips of the half-herringbone tines project to a point where they each intersect the mid-region of a related hammer. The tips of the half-herringbone tines are welded to the hammers at the points of intersection. The portion of said half-herringbone tines passing over hammers other than the hammer to which a particular half-herringbone tine is welded are undercut to prevent rubbing between the half-herringbone tines and the hammers over which the half-herringbone tines pass, but with which they are not associated.
