An overtravel stop for a rotating shaft has a pair of gears associated with the shaft to rotate therewith. Each gear engages an associated limiting gear and the two engaged gear pairs have different gear ratios. One of the limiting gears is threaded over a shaft which is secured for rotation with the other limiting gear, such that the different gear ratios causes the one limiting gear to translate over the shaft. At selected travel limits, the one limiting gear is caused to lock relative to the other, thereby causing one of the gears associated with the ...
An overtravel stop for a rotary shaft, comprising: a fixed stop; a following member about the shaft and adapted to rotate with the shaft within its selected travel limit, said following member being associated with a stop member; a cam structure between the shaft and the stop member, said cam structure being adapted to axially move the stop member into engagement with the fixed stop; means for engaging the cam structure when the following member rotationally shifts with respect to the shaft; and means for rotationally shifting the following member with r...
