Abstract: A clutch and lock mechanism adapted for use with a double shuttle table utilizing two individual drive shafts wherein a first shaft ring assembly is fixedly coupled to a first shaft and a second shaft ring assembly is coupled to the second shaft. The first and second shafts and shaft ring assemblies are spaced from one another along the common axis of rotation of the first and second shafts and an engaging mechanism is positioned between the two shaft ring assemblies and movable therebetween. When the engaging mechanism, at least a portion of which is rotationally locked to the second shaft, is moved to a first position, it is rotationally locked to the first shaft and rotation of the first shaft thereby results in the rotation of the second shaft. When the engaging mechanism is moved to a second position, opposed to the first position, it is disengaged from the first shaft and prevents the rotation of the second shaft.
