Abstract
Intermittent screw thread geometry with a rapid step-wise lead feature when external threads are engaged with internal threads of reflective geometry. In an embodiment, thread segments are alternated with unthreaded segments of equal arc length along a helical path of a single-start thread form which results in an odd number of alternating thread/gap features along the helical path per revolution of the thread body. When such external intermittent threads engage internal intermittent threads of reflective geometry, an external thread body can be axially advanced or retracted through an internal thread body in a rapid step-wise fashion by turning the external thread body in either the clockwise or counterclockwise direction, or in both directions alternately, with respect to the internal thread body when a net axial force is applied to the external threaded body with respect to the internal thread body in the desired linear direction of travel.
