Fuller's "Time Telegraph" was a circular nonlogarithmic slide rule, designed by Fuller in 1844 and intended for calculating the number of days or weeks between any two given dates. The title reflected the fascination with the new high-speed telegraphic technology, implying high speed in calculation. On the other side is a later, improved edition (Feazel's issue 4) of "Palmer's Computing Scale," the copyright of which had been purchased by Fuller in 1844 or 1845 (Feazel, "Palmer's computing scale," Journal of the Oughtred Society 3: 9-17; see pp. 11-15).

This item represents a very early use of the word "computer" for a machine rather than a person. Until the invention of electronic computers in 1945, the term "computer" usually referred to a person who compiled mathematical tables with or without mechanical assistance. Sometimes the term referred to "lightning calculators" who performed remarkably fast computations in their heads. During the first decade of electronic computing, the term was apparently used interchangeably for people and machines. By about 1960 the word was generally applied only to machines.
