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.
