By 1911, it was possible to buy oscillating, cylinder, domestic washing machines with sheet metal tubs mounted on angle-iron frames with perforated metal or wooden slat cylinders inside. Manufacturing Challenges From a technological perspective, washing machine manufacturers faced a number of challenges. These included discovering a method of transferring power from the motor to the mechanism, finding a su
