I wonder if they were any different than the HotPoint top loaders here? There's three basic designs I run into, GE/HotPoint with the centrifugal clutch driven water pump, belt drive Whirlpool with a wig-wag used to shift the transmission, and the modern direct drive Whirlpool with a rubber coupler between the motor and transmission rather than a belt. Most top load washing machines are one of those three internally regardless of the brand slapped on the outside and not much has changed, you can still get parts for a 30 year old machine in most cases.



The Hotpoint top loader I refer to has a cenfigugal clutch below the (induction) motor to drive the gearbox (power unit) via a belt, and the pump is directly above the motor driven via a flexible rubberised canvas coupling known to repairmen as the 'Chinese lantern' because of it`s shape. The top of the motor has a large fan/umbrella to deflect water that inevitably leaks from the pump.

The Whilpool (Phillips) machines were French and had the drum mounted much like a front loader except you put the washing in from above via a trapdoor in the drum. Transmission is/was via a bakelite variable centrigugal drive using a pair of tapered pulleys and 3 ballbearings. As the motor speed increases the two pulleys are forced together by the ball bearings which increases the diameter. The later of these machines used a low voltage permanent magnet motor (the same motor as in the Sinclair C5!) the voltage being dropped by the heating element.
Horrible machines to work on.
