Apparatus for producing type

Claim 1

Apparatus for forming relief characters on a typebar comprising: a. a frame member; b. a temperature-controlled matrix of engraved characters carried by said frame member, wherein said matrix of engraved characters comprises c. a plurality of bar elements in contiguous, relatively slidable, side-by-side relation, adjacent edge portions thereby forming a substantially coplanar surface; d. each bar element defining a forward and rear end portion; e. said coplanar surface exhibiting a plurality of spaced-apart engraved characters along a portion of the longitudinal edge of each adjacent bar element; f. means securing the relative positions of the bar elements, wherein said means comprises g. a plurality of serrations at the rearward portions of each bar element; h. a first and second lock bar means in relative slidable sideby-side relation; i. means resiliently biasing said first and second lock bar means in coacting, engaging relation with the aforesaid serrations of each bar element; j. means carried by said frame and operably connected to said lock bar means for selectively disengaging the first and then the second lock bar means in sequence from said serrations; k. means for selectively positioning a line of said characters; and l. means carrying a deformable, blank typebar into coacting relation against said character matrix causing a plastic deformation of the typebar in conformance with the engraved characters contacted thereby.
