Dover egg beater
A cranked whisk with two rotating dashers and gears – one of the first mechanical kitchen tools.

Materials: Cast iron, tinned steel
Manufacture: A large gear wheel with a crank drove two small pinions that turned the dashers in opposite directions.
The large crank wheel and the two dashers turning against each other.
