Typewriter of the typebar, upstrike class manufactured by the Smith Premier Typewriter Company of Syracuse, New York, U.S.A. The design of this machine was first patented in 1889 by Alexander Timothy Brown of New York and production began in the same year. The Model 4 was first produced in 1896 and remained in production in various forms until 1908. This typewriter is of the upstrike variety in which the typebars strike the underside of the platen. The printed characters are thus not immediately visible to the operator who must tilt the platen and carriage upwards and backwards to see what has been typed. In 1908 the Model 10 was introduced. This was a front strike machine in which the typebars struck the front of the platen and the typed letters were directly visible to the opeartor.
