Lee S. Burridge and Newman Marshman designed the first of several very similar linear index typewriters, patented in 1885. Other mechanically similar machines of the time include Pearl, International index, New American and Odell.
In 1899, Burridge patented a small frontstroke 3-row typewriter with a novel inking device in which the typebars were inked by a roller before striking the platen, and the ink roller itself kept well-inked by a larger booster ink roller. Later models abandon this system for standard ribbon inking.
Nine models were manufactured by the Sun Typewriter Co. over the years and marketed in different countries in a variety of names, including Carlem, Leframa, New Sun, Nova and Star.
