Hawk, L S; Turner, J H

A manual-type braille writer is described that provides for both writing and reading in a normal left-to-right manner. In the preferred form, this braille writer has a clip board type base, and in the preferred embodiment a guide plate assembly can be moved to, and releasable fixed at, selected vertical locations along this base. The guide plate assembly is provided with a plurality of character cells uniformly spaced along rows across the guide plate assembly as well as in uniformly spaced rows. This guide plate assembly has a lower portion to be placed under a sheet of paper positioned on the clip board base and an upper portion to be positioned on top of the sheet. This upper portion is hinged with respect to the lower portion. Each character cell is typically made up of six appropriately spaced pins extending up from the lower portion that are aligned with a rosette-shaped cutout in the upper portion. A stylus member is provided that has a distal end to be fitted into the cutout of the character cell so that a recess in the end thereof presses the writing paper over the pin associated with that recess to produce a braille dot at that location. When desired, the upper portion can be lifted up so that the text already written can be read or to determine the place for initiating writing when writing has been interrupted. 10 figs.
