ABSTRACT:
A motion transmitting and timing mechanism including an input gear 36, a timing gear 44 rotatable about an axis 50 and meshed with the input gear 36, and an output gear 64 rotatable about the axis 50 and shiftable along the axis into positions in and out of a plane including the input gear 36. The output gear 64 has a toothed sector 66 and an untoothed sector and a spring 76 and detent 72 arrangement normally maintain the untoothed sector in axial alignment with the input gear 36. A threaded connection 46, 70 between the timing gear 44 and the output gear 64 effects axial movement of the output gear 64 upon relative rotation between the two and a jaw 82 carried by the timing gear 44 is engageable with the output gear 64 for moving the toothed sector 66 into mesh with the input gear 36.
