Cutler-Hammer Regulator, circa 1915
- Cutler-Hammer Rheostat, 1898-1920 - Rheostats vary the amount of electrical resistance in a circuit. They proved beneficial as the use of electrical power expanded in the late 1800s. Among their many applications, rheostats helped motors start safely, controlled motor speed, maintained a constant current in battery chargers, and adjusted volume and light levels.

- Motor Controller Used at the Yerkes Observatory, Williams Bay, Wisconsin, circa 1897 - Yerkes Observatory in Williams Bay, Wisconsin is known as the birthplace of modern physics for the volume and importance of research conducted there. It is also home to the world's largest refracting telescope. When it opened in 1897, the observatory included an adjustable floor and a rotating dome, governed by motor controllers made by Chicago-based Cutler-Hammer Manufacturing Company.
