Inventors C. Latham Sholes and Matthias Schwalback of Milwaukee, Wisconsin, submitted this typewriter model with their patent application for an improved up strike key lever mechanism for printing onto paper. The inventors received number 182,511 on September 9, 1876. The typewriter has two rows of keys in roughly alphabetical layout as well as the numbers 7 and 8. When struck, the keys would rise up and hit the piece of paper lying horizontally on the platen of the typewriter. The carriage would have to be lifted for the typist to see their typed words.
