They consist of a Frame, on which are Sets of Letters arranged in Alphabetic order. These letters are fastened to the frame by a button sliding in a groove, and can be carried to any part of the frame separately, and formed into words and sentences in grooved lines made for that purpose in the upper part of the Frame.
