Foreign Transorma.

The Post Office Department tested the Gehring Mail Distributing Machine, created by Casimir Gehring 1923, which automatically sorted letters into 120 receiving boxes or “pigeonholes”. They representing cities or states, based on the clerk’s keystrokes. The machine was the brainchild of Casimir Gehring, manager of the Mechanical Efficiency Company of Akron, Ohio. Name of this mashine is not known.

The Transorma machine was demonstrated in 1927 and the first machine was installed in Rotterdam, Holland in 1930. The mashine was used until July 1968. In Brighton, England they installed two Transorma 1935. Other countries using Transorma machines were Argentina, Belgium, Brazil, Canada, Germany, Phillipines, Sweden, USA and Venezuela.  Most of the cyphers are red but there is black too. Even Sweden were testing the machine, but it did not work properly.

The name came from TRANsport and SORting Marchand Andriessen)
