ABSTRACT:
A linear motor provides stepwise, incremental advance of a moveable output member. First and second, spaced latches are movably coupled to the output member. A selectively energizable driver engages and moves the first latch into fixed engagement with the output member and continues to move the engaged first latch and output member a predetermined incremental advance distance. The second latch is biased to retain the output member in each successive incremental advance position while the first latch is being reset. In one embodiment, the driver is a motor having a rotatable output shaft with an eccentric cam mounted thereon. The eccentric cam engages the first latch to move the first latch into fixed engagement with the output member and to advance the fixedly engaged first latch and output member an incremental advance distance. A second latch is provided to hold the output member from movement in a direction opposite from the incremental advance direction. A movable, two-position yoke is provided with shift springs acting on the latches to reverse the function of the first and second latches alternatingly between driving and holding functions depending upon the position of the yoke. The yoke is moved in opposite directions by two, oppositely arranged, unidirectional cams which engage drive pins mounted in the yoke upon selected rotation of a drive motor driving the cams.
