English: Hammond Model 1B typewriter from a Saskatoon newspaper around 1910, shot at Western Development Museum, Saskatoon, Canada. Invented by James Bartlett Hammond in the 1870s and manufactured by his Hammond Typewriter Co. in New York starting in 1884, the Hammond had some unique features. The typefaces were on two semicircular typewheels, and could be changed, allowing the typewriter to type in different fonts and alphabets. Instead of typebars striking the paper, a hammer behind the page strikes a rubber sheet, driving the paper against the ribbon and typewheel. One of the first typewriters that allowed the typist to see the page as it was being typed. Information source: Richard Milton, Hammond, Portable Typewriters website
