notes: label: Description (Brief)
content: A wooden table (right leg broken), brass mechanism, wooden wheel, brass clock-works and train of wheels and guides-engraved plate on top of table. Number 3 of three model to accompany US Patent #6328, "Automatic Telegraph," issued 17 April 1849 to Alexander Bain. This instrument was patented in London, England 12 December 1846 and probably made in London in 1848. The instrument was designed to permit simultaneous transmission to and from one to six stations (one message to not more than six separate stations). To avoid any conflict with Morse patents no electromagnets are used. Bain claimed three inventions with this instrument: 1) Use of paper tape punched with small circles according to definite code; 2) Sending electrical impulses when the paper tape opened and closed the circuit; 3) Receiving these impulses or signals on chemically prepared paper, the electrical impulses directly marking the paper. No secondary electrical current or mechanical contrivance was necessary to interpret the signals, according to the inventor.
