The Lift

The world's first fax machine was patented in 1843 by Alexander Bain. He came from a remote croft in Caithness in Scotland and, for his early experiments, used cattle jaw bones for hinges and heather for springs. His fax machine was based on an electric clock, which he had also invented. Episode Contents: Models: The "human fax" had Tim and Rex stand at opposite ends of a big field. Tim steps slowly over a sheet printed with giant letters of a message and uses coloured paddles to signal Rex who walks over a similar large sheet with a paint roller, applying paint when he sees the signal. Everything is synchronized with a metronome. The next model uses a board with nail at one each end which closes a circuit in contact with raised metal type. The current causes the nail at the other end to heat a sheet of paper soaked in potasium ferra cyanide. A "string fax" consisting of two drums shows how a picture can be transmitted one line at a time. The "lathe fax" uses a light detector hooked up to a buzzer which is then transmitted through the headset of a normal phone. A lathe at the other end has a sound switch which sends a current through the treated paper at every pulse from the sender lathe. The 2nd "human fax" emulates a digital fax with large grids placed over both Tim and Rex's sheets. Guests: A pair of French Pantelographe de Casell c.1860. A hydrogen balloon used for weather telemetry. A modern fax analyzer. Films: Cartoon life of Alexander Bain (patenter of the fax 150 years ago). Old newsreel featuring early developments in newsgathering. 70's xerox office fax ad. Extro: Tim's homemade Pantelograph.
