Date Aug. 5, 1993.The invention relates to a machine having a carriage for movement on a floor surface. The carriage has structure for rocking the carriage with respect to a floor surface. A workhead assembly is pivotably mounted on the carriage for movement between a first working position and a second rest position. A biasing structure acts on the workhead assembly to move the workhead assembly from one of the positions to the other. Rocking of the carriage allows the workhead assembly to move under influence of the biasing structure from one position to the other position.
