Abstract
A timing gear device includes a first rotatably supported shaft, a first gear, having a predetermined number of circumferentially spaced teeth, engaged on and carried by the first shaft and a second rotatably supported shaft spaced from the first shaft. A second gear having a predetermined number of circumferentially spaced teeth is engaged on and carried by the second shaft. The first gear and the second gear are engaged with each other. A timing device is provided for changing the rotative position of the second shaft and the second gear in relation to the first shaft and the first gear. The timing device includes a single primary keyway in one of the second gear and the second shaft and a plurality of secondary keyways in another of the second gear and the second shaft. The secondary keyways have differing configurations. A key is provided in the primary keyway. The key is engaged in a predetermined one of the secondary keyways to establish a driving engagement between the second shaft and the second gear.
