Globotype

The Globotype is a color display for telecommunications. It was invented and patented by David Mc Callum of Stonehouse, Devon, England. The device features very low cost and does not use consumable supplies. It is Royal Letters Patent No. 2924 issued December 29, 1855. The design and coding used is described in "Froehlich/Kent Encyclopedia of Telecommunications", Volume 2, pages 461 and 462.

The inventor published a small booklet in 1856 entitled: GLOBOTYPE TELEGRAPH: A recording instrument in which small coloured balls are released one by one and made to pass over a series of inclined planes by the force of gravity. The booklet was originally published by Longman, Brown, Green, and Longmans of London.
