ABSTRACT:
The present invention is an impact print bar assembly (10) adapted for installation in a typewriter, character printer or other device adapted for linear application of printed characters to sheet material. The assembly (10) includes an impact print bar (12) which is adapted to be held within a bar holder (14) in any of four different orientations, each of the orientations presenting a different print surface. The impact print bar (12) provides a solid, non-rotating, surface for the sheet material to reast against during printing. The impact print bar (12) includes a central support rod (28) having a resilient, usually plastic, body (36) formed thereabout. The degree of hardness of the body (36) may be varied, depending on the application desired. The support rod (38) has a square cross-section such that it will fit into the hollow frame (52) of the bar holder (15) in any of the four orientations. The print bar (12) is held within the bar holder (14) by a retention clasp (54), (56) such that it is a firm backup material for the paper during the print process. The primary commercial utilization of the invention is in impact printers such as daisy wheel, print thimble, print ball and dot matrix devices.
