  • Intermittent geneva actuated mechanism
    Patent number: 6209404
    Abstract: An apparatus (10) includes a manually rotatable input member (15), an input gear (20), an output gear (40), a drive link (60), a first planar link (80), and a second planar link (90). The input gear (20) is operatively connected to the input member (15) to rotate with the input member (15). The input gear (20) includes a smooth portion (26, 28) and a toothed portion (22, 24). The output gear (40) has teeth (42, 43) which are operatively engageable with the toothed portion (22, 24) of the input gear (20) such that the toothed portion (22, 24) of the input gear (20) imparts rotation to the output gear (40). The smooth portion (22, 24) of the input gear (20) allows rotation of the input member (15) without imparting rotation to the output gear (40). The drive link (60) is connected to the output gear (40) such that rotation of the output gear (40) imparts rotation to the drive link (60). The drive link (60) has an engagement pin (62) which is rotatable with the drive link (60).
