Description
The nature of Hayden's invention "consists in placing as many levers side by side as you desire to make the letters or figures, each lever having elevated upon its upper edge the number of dots and lines which, according to the Morse combination, constitute any given letter or figure, and placing the levers, when complete, underneath a finger-board whose surface is perforated with openings through which the raised dots and lines may protrude... the surface of said finger-board being fluted, so that the slots or openings may be in the center of the groove or flute."
