M 5. mm.



Application filed December 14, 1920.

T 0 all whom it may concern:

Be 1t known that I, SAMUEL S. NIGKERSQN,

a citizen of the United States of America, and resident of Llsbon, in the county of the accompanying drawings, which form apart thereof.

My invention relates to writing tablets for the use of the blind and has for its object to provide a tablet upon which a sheet of paper can be fastened and which will be formed with embossed parallel lines or ribs of such a character that they will be easily felt through the paper sheet by a blind writer and thus enable him to write between the ribs in parallel lines. Guide tablets having raised or depressed ribs have been heretofore provided for blind writers and my invention consists in the improvement by which I form on such tablets embossed parallel ribs having rough or serrated edges which ribs I have found furnish a much more easily felt and reliable guide for the fingers of a writer than is provided by any known writing tablet.

My invention is illustrated in the drawin g in which- Specification of Letters Fatent.

Patented Mar. 15, 1921.

Serial No. 430,701.

Figure l is a perspective view of my improved tablet with a fragment of a paper sheet secured on its surface and Fig. 2 is a cross section on line 2-2 of Fig. 1.

Kris the tablet formed of thin and fairly stiff material such as a thin sheet of metal or of fiber board. On the face of the tablet are formed the parallel embossed ribs indicated at B, B, etc., and each of these ribs is so formed that its top edge is rough or serrated presenting to the fingers of the writer a series of elevated points as shown at C, C, etc. D, D, indicate spring clips for securing a sheet of paper E on the face of the tablet.

The method of using my improved tablet 's, or course, obvious. I may say, however,

1 the the lines or ribs of embossed points owing to their resemblance to the Braille SAMUEL S. NIGKERSON.
