ABSTRACT:
A drive engagement mechanism for providing selective engagement with a drive shaft where the drive shaft includes a surface having a discontinuity. The engagement mechanism includes a cylindrical hub with an external surface and an aperture extending along the longitudinal axis of the cylindrical hub. The hub includes a protrusion for engaging the discontinuity on the shaft and a surface for allowing rotational and sliding support of the hub against the shaft. The hub is mounted within a support frame that provides sliding and rotational support to the hub from the external surface of the hub, so that the hub may slide along the axis from a first position where the protrusion engages the discontinuity on the shaft, to a second position where the protrusion does not contact the discontinuity and thus disengages the shaft. Structure for moving the hub from the first position to the second position is also provided, so that the hub is supported next to the shaft by the support frame and so that when the hub is in the first position the hub engages the discontinuity on the shaft to transmit power from the shaft and when the hub is slid to the second position the hub is disengaged from the discontinuity.
