Link 1 rotates about fixed axis A and is connected by turning pair B to link 5 which has gear rack a. Rack a meshes with pinion 2 which rotates about fixed axis C. Link 5 is suspended by spring 6 from the body of the machine. When driving link 1 rotates, pinion 2 oscillates together with the washing drum as long as cam 3 is in the position shown. Cam 3 turns about fixed axis E and is connected by turning pair N to link 7 which, in turn is connected by turning pair M to handle 4. Handle 4 turns about fixed axis K. When handle 4 is turned clockwise, cam 3 is turned and spring 6 raises rack a out of engagement with pinion 2. This stops oscillation of pinion 2 and the washing drum.
