ABSTRACT:
A timing mechanism (10) is provided in which input gear (11) is fixed on one shaft (12) for operating one system such as a door to move between two positions. A differential nut (14) is also provided on the shaft (12) for axial movement therealong. The differential nut (14) meshes with a first translating nut drive gear (2) rotatably arranged on a second shaft (19) which also contains a second translating nut drive gear (36) rotatably arranged thereon. The second gear (36) meshes with a differential nut (32) axially movable along a third shaft (26) for actuating a second system such as a pallet between two positions. The timing mechanism (10) is utilized in a system in which the output of each differential nut (14,32) is caused to operate a brake so that only one system will be in operation and the brake in the other system will not be released until the one system has completed its movement to a desired position.
