The Machines: Yost

[image error]

George Yost had been involved with Sholes & Glidden and Caligraph before launching his own machine in 1888.  It was an upstrike, blind-writing machine (meaning the typist could not see what was being typed).  The typebars were arranged in a ring against a circular ink pad which resulted in perfectly aligned typeface (no ribbon to hinder the alignment).   The Yost did not utilize a tab to separate upper and lower case letters, instead providing a full keyboard with keys for each.
