Abstract

542,003. Typewriters. GRIS, H. J. L. JEANNERET. June 7, 1941, No. 10045/40. [Class 100 (iv)] A braille-writing machine comprises a casing 90 provided with six slidable marking-pins 01 .. 06, and four finger-keys 2 .. 6 and two thumb-keys 4, 1 operable accordion-fashion by one hand, operation of one or more keys causing the corresponding marking-pins to be locked by means of catches 21 .. 26 so that when the casing is depressed or, preferably, is rocked downwards about a supporting bar 80, the selected marking-pins emboss the sheet. The pins are provided with returning-springs 41 .. 46. The bar 80 may be formed at letter-spaced intervals with grooves co-operating with a spring-ball 82 in the casing. The marking-pins are provided with returning- springs 41 .. 46. To prevent damage by depressing a key erroneously when selected marking-pins have been locked, yielding connections are arranged between the keys and catches.
