Abstract
Abstract The selectively reciprocable pins of a mosaic printing device are guided in a series of holes defined by corundum bearing plates. The holes are precisely oriented relative to the printing head by cementing the plates in a polygonal recess in a support, the sides of the recess precisely locating the plates relative to the support. The support in turn is fixed in the printing head with a plurality of flat surfaces on the support in contact with a plurality of flat surfaces on the printing head, thereby precisely to orient the support and hence the holes relative to the printing head.

Claim 1
Independent Claim
205 words
A support for a pin guide, and a head to which said support is secured, said support having a recess therein, a pair of plates cemented in said recess, said plates having opposed edges that define openings between said opposed edges, said support having a cylindrical rear projection that engages in a cylindrical opening in said head, said recess and said plates having a plurality of flat surfaces that are in area contact with each other and that are perpendicular to the axis of said cylindrical rear projection, said recess and said plates having further flat surfaces that are in area contact with each other and that are parallel to said axis, said recess being defined by said flat surfaces thereof, said support and said head having flat surfaces that are in area contact with each other and that are perpendicular to said axis, said support and said head having further flat surfaces that are in area contact with each other and that are parallel to said axis, said further flat surfaces of said support and said head including at least one flat surface on at least one projection that extends forwardly from said head, and a setscrew releasably securing said support in said head.
