Austin Burt, the great grandson of the inventor, built a working model of the typographer for the 1893 Chicago's World's Fair working from a parchment copy of the original patent (USX 558111). He explained in a letter dated April 1, 1893, that was attached to the model that it took him a month to construct it from the original patent description because many of the parts had to be hand-made. The details of the construction of the machine provided by the inventor are so complete that any competent mechanic can build a working model. Austin's model was on display and a picture taken of it at the University of Minnesota just prior to going to the Chicago's World's Fair in the middle of April. The younger Austin then was a student of engineering at the University. The replica built by Austin was returned to the model room of the Patent Office in Washington D.C. when the Chicago's World's Fair closed. There it remained until 1903 when the Patent Office model room was closed. The "typographer" was then shipped in 1903 to Hiram A. Burt of Marquette, Michigan. Burt's machine and the original Letters Patent went to Hiram's daughter, Mrs. Howard Corning, of Bangor, Maine, when Hiram moved to Maine at a later date. The replica has been since 1922 in the Smithsonian Institution, and the documents of the original letters patent stayed in the family of Mrs. Howard Corning.
