A short, silent, black and white film showing the various parts of a teleprinter in action.
Teleprinters were invented in order to send and receive messages without the need for operators trained in the use of Morse code. A system of two teleprinters, with one operator trained to use a typewriter, replaced two trained Morse code operators. The teleprinter system improved message speed and delivery time, making it possible for messages to be flashed across the country with little manual intervention.
The film focuses on each aspect of the electronic device, concluding by producing the message ‘Time for all good men to come to the aid of the party’.
