| Description |
The Hoff Aid is an upward-writing slate and is designed primarily for use in making mathematical calculations on paper. Its main advantage lies in the fact that it permits examination of the brailled characters at all times without having to remove the paper from the slate. It is not designed for taking notes and the like, since it does not permit the necessary speed in writing. Metal slate has one line of 30 cells. A steel rod is slotted at 1/4-inch intervals. A movable die-box is fitted with six inverted, conically shaped caps the size of the braille dots on the metal sheet. A hinged paper holder fits into the left side of the slate; not included with this accession. A stylus depresses the caps to form braille dots. "Amer. Printing House For The Blind.
