Teletype Model 28


The Teletype Corporation, a part of American Telephone and Telegraph Company's Western Electric manufacturing arm since 1930, came into being in 1928 when the Morkrum-Kleinschmidt Company changed its name to the name of its trademark equipment.

The Teletype Model 28 (1951) is a product line of page printers, typing and non-typing tape perforator and tape reperforators, fixed-head single contact and pivoted head multi-contact transmitter-distributors, and receiving selector equipment. Regarded as the most rugged machines that the Teletype Corporation built, this line of teleprinters used an exchangeable type box for printing, and a sequential selector "Stunt Box" to mechanically initiate non-printing functions within the typing unit of the page printer, electrically control functions within the page printer and electrically control external equipment. The Teletype Corporation introduced the Model 28 as a commercial product in 1953, after this product had originally been designed for the US Military.

Because of the nature of its business, as stated in the corporate charter, Teletype Corporation was allowed a unique mode of operation within Western Electric. It was organized as a separate entity, and contained all the elements necessary for a separate corporation. Teletype's charter permitted the sale of equipment to customers outside the AT&T Bell System, which explained their need for a separate sales force. The primary customer outside of the Bell System was the United States Government.
