This was an early mechanized washing machine. A friend's family had one when she was a little girl called the 1910 Cataract. Cataract is another name for a waterfall--see Nile River. Anyway you notice that the tub has ribs like a washboard. Once the water and soap and clothes were loaded and the top put on, this tub would gently rock back and forth, tilting side to side, rubbing the clothes over the ribs and cleaning them as they sloshed in the water. It is sort of like a tumbler that does not make a full circle and instead of tub vanes to lift the clothes to tumble, they are moved by passing over the ribs which slow the movement of the items on the bottom and help create disturbances in what would otherwise be just side to side sloshing. When the washing was finished, the clothes went through the wringer into tubs for rinsing.
Hurley was an old name in industrial works. There was a Hurley Boilerworks. The Hurley Machine Co. was behind the first electrically operated washer produced in 1908, designed by Alva Fisher and marketed under the brand name Thor.
Sometime in the late 50s or early 60s, Westinghouse had an ad campaign that showed laundry running over small rapids in a strean and said that the tumbling action was like allowing the clothes to run a mile over the smooth river rocks in the stream bed. I guess this was based on the number of peripheral feet in the circumference of the drum, the number of peripheral feet the drum traveled per minute and then the total distance that would be in the minutes of a wash cycle. The ribs in the Hurley tub were designed to give a similar action. When Westinghouse went to the non-tilted tub, the tub wall had mini ribs between the 2 vanes, something even Bendix had not used or patented.
I wonder if the term "hurley" was ever used to describe a state of nausea as in, "I feel sorta hurley," or a state in which someone has been throwing up, "he's been hurley most of the morning."?
