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