Definitions

  • My invention relates to a device or game by which one may reproduce the succession of sounds or taps which make up each character of the telegraph-code. I attain this by the mechanism illustrated in the accompanying drawing, in which- A is a card of pasteboard or other suitable material. The edge or edges of this card are so notched that if a strip of pliable material B is drawn across the notched edge the succession of sounds or taps produced will reproduce some character of the telegraph-code.
