| Provenance/History |
This item might have been produced at APH circa 1890. However, unlike the McElroy punctograph made at APH as described in the book "The Technological Origin and Development of Mechanical Writing Devices for the Blind," this punctograph is six-dot with six keys instead of two. The McElroy Point Writer, one of the earliest upward writing point writers, was patented by James McElroy in 1888. The machine wrote in New York Point. This writer, by an unknown maker but operating on similar principles, was intended to write in American braille. |
