Description
The American inventor Edward Hebern (1869-1952) designed a series of machines for encrypting messages. The Smithsonian collections include a few of these as part of accession 1991.0190. Like many inventors, Hebern accumulated a variety of spare parts. These are some of them, part of museum transaction 1991.3033.
This device includes a black motor on a metal base. A vertical bakelite circuit board is in front of the motor. Green wires from the top of the circuit board attach to a wheel to the right of the motor which is apparently driven by it. Red wires from the bottom of the circuit board are held together with tape and attach to a socket. There are lettered lugs at the ends of the red wires that attach to the circuit board.
