The machine has parallelogram-shaped linkages which serve to move built-on appliances. It consists of two parallelograms (48,50) whith a common lever(30) whereby the first part (54) of the lever forms one side of the first parallelogram (48) and the second part (58) forms a side of the second parallelogram (50). Near the linked structure is a fixed lever (22) on which the first common lever is hinged.
