HISTORICAL REMARKS: **************************************************************************** based on: (1st) R.MILTON's HomePage http://www.portabletypewriters.co.uk (2nd) Book of M.ADLER » Antique Typewriters « / Schiffer (1997) The principle was patented 1880 to James Bartlett Hammond, a shorthand court reporter without engineering training. He used an arc of a circle to swing the fonts on a shuttle in place. Printing was performed by means of a hammer from the rear striking the paper against the font with a ribbon in between. There was no way for a sheet of paper to enter in conventional manner. His solution was to use a cylindrical basket in the carriage into which a rolled up blank sheet of paper was first inserted. This inconvenience was tolerated because his typewriters were indisputable the best machines of its time. The regularity of typing was unparalleled and the ease with which type shuttles could be interchanged made this typewriter the most versatile on the market: Hundreds of alternative languagues, alphabets, scripts & scientific symbols were available. The »HAMMOND« was produced until 1920. After J.B.Hammond's death a new shareholder, Frederick Hepburn, changed the comany's name to »VARITYPER«. After depression the company was bought by Ralph C.Coxhead and improved versions of the »VariTyper« were in use until the 2000s.
