Burroughs Adding Machine Section

Description
This open cross section of a Burroughs adding machine has a metal frame painted black on one side, a single column of nine plastic-covered keys (one of these is missing), a mechanism for the keys, a short rubber carriage, and type. Two number wheels are at the front. Places where the mechanism and frame have been cut off are painted orange. The model is supposed to show transmission of action from the finger keys to the registering devices. The model rests on a metal shaft that is attached to a square wooden base.
This section was lent to the Smithsonian in 1924 by Burroughs Adding Machine Company of Detroit as an example of the technology of a current product. It recently has been donated to the Institution by Unisys Corporation.
