Zusammenfassung:	In the improvement, the slot portions are in a plate fixed with respect to the control lever. The mechanism includes an auxiliary lever and a selection device mounted for movement by the auxiliary lever for selecting a slot portion. The mechanism is used in an apparatus for manipulating plural valves. Such apparatus has two control assemblies, each having a valve control lever coupled to its respective plate, and two auxiliary levers. In a specific embodiment, each auxiliary lever is coupled to a selection bracket having parallel quadrant members with a selection device, e.g., a pin, mounted between the members. The pin is retained in registry with the selected one of the slot portions by a retention mechanism bearing against the selection bracket.
