Abstract
A compound differentially threaded element engages two or more longitudinally severed segments of a mating threaded element to provide differential linear motion. Different thread types may include pitch, thread starts, handedness or thread-form. Combinations of differential threads may be selected to enable fine or coarse linear motion without correspondingly fine or coarse thread pitches.
