The First Washing Machines The earliest manual washing machines imitated the motion of the human hand on the washboard, by using a lever to move one curved surface over another and rubbing clothes between two ribbed surfaces. This type of washer was first patented in the United States in 1846 and survived as late as 1927 in the Montgomery Ward catalogue. The first electric clothes washers, in which a motor rotated the tub, were introduced into America about 1900. The motor was not protected beneath the machine and water often dripped into it causing short-circuits and jolting shocks. 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
