Royal KHM Typewriter

This Royal KHM model typewriter was produced by the Royal Typewriter Company of Hartford, Connecticut in 1934. The Royal KHM was very similar to the Royal 10, but notable differences include plastic instead of glass sides, no scooped center, and covered ribbon spools.
The Royal Typewriter Company was founded in 1906 by Thomas Fortunes Ryan and Edward B. Hess, with Ryan providing the capital and Hess providing the inventiveness. Hess owned over 150 patents, many of which were assigned to the Royal Typewriter Company. Hess’s most noteworthy patents related to increasing the ease of typing, including an accelerating typebar, anti friction roller escapement, Magic Margins, and selective touch control. In 1954 Royal merged with the McBee Corporation, operating as Royal Mcbee until 1964. In 1964 Royal McBee was acquired by Litton Industries, which used Royal as a brand until 1968.
