Chicago Apparatus Hand Crank Dynamo Electric Machine Antique Physics Laboratory

Chicago Apparatus Co Miller-Cowen Dynamo Electric Machine Antique Physics Lab. Handle crank action is smooth as silk. The baseboard original finish was touched up with some fresh lacquer to bring it back to standard. Offered here is a rare Chicago Apparatus Co.

This antique physics lab piece is a fascinating example of early electrical generation technology. Designed for classroom use allowing students to experiment with both AC and DC Dynamos. Generates between 20 and 20 and 40 milliamps when the taps are connected to a 6 volt lantern battery. A must-have for collectors of scientific instruments and those interested in the history of electricity.

Condition, was tested and found to generate milliampere power in both AC and DC configurations. Please see photos for details.
