These were interesting in many ways. They were redesigned James dishwashers. They were among the smallest major appliances of the late 50s-early 60s and were often seen in boat galleys. They normally did not have a pump so they used a gravity drain which is why they were mounted above sink level. The portable model did have a drain pump and had a cart that looked remarkably like a cart for a portable TV in the 60s. These filled and washed then gradually filled so that the wash water overflowed down the drain and was replaced by rinse water. At the end of the cycle the steam generator fogged the load with steam which condensed on the dishes essentially giving them a final rinse with distilled water. The steam heated the dishes to where they dried with their own heat. The timer was a spring-wound device; you turned it all the way to the end and it ticked down through the cycle. It might have been the only spring-wound timer used on a dishwasher. The dishwasher came in three sizes. I can't remember for sure, but I think it was 4,6,10 or 6,8,12 place settings. Loading was very regimented, but the rack for glasses could be removed for loading large items. John found one without the glass in the door and then another one with the glass, I think. These did not handle food particles especially well because the twisted blade that made the spray rotated in a perforated tube with a slit at the top. The mechanism that rotated the blade made the tube oscillate back and forth. Bits of food would clog the holes in the tube which was hard to clean and there was no way it could be called self-cleaning or self back-flushing.
