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.
Claims11
An adjustment bracket comprising:
- an adjustment shaft, with said shaft having at least a first and a second external thread path, with said first thread path being different in configuration from said second thread path;
- an adjustment bracket for engagement with said adjustment shaft, with said adjustment bracket comprising having at least a first and second internal thread path for engagement with said first and second thread paths of said adjustment shaft;
- wherein
- rotation of said shaft or bracket in relation to each other results in differential movement of at least two subunits of said shaft or said bracket.

An adjustment bracket comprising:
- an adjustment shaft, with said shaft having a first subunit with at least a first external thread path, and a second shaft subunit with at least a second external thread path, with said first thread path being different in configuration from said second thread path;
- an adjustment bracket for engagement with said adjustment shaft, with said adjustment bracket comprising at least a first and second internal thread path for engagement with said
- first and second internal thread paths of said adjustment shaft first and second subunits;
- wherein
- rotation of said adjustment bracket in relation to said adjustment shaft results in differential movement of at least two subunits of said shaft.

An adjustment bracket comprising:
- an adjustment shaft, with said shaft having at least a first and a second external thread path, with said first thread path being different in configuration from said second thread path;
- an adjustment bracket for engagement with said adjustment shaft, with said adjustment bracket comprising a first bracket subunit with at least a first internal thread path for engagement with said first thread path of said adjustment shaft, and a second bracket subunit with at least a second internal thread path for engagement with said second thread path of said adjustment shaft;
- wherein
- rotation of said shaft or bracket in relation to each other results in differential movement of said subunits of said adjustment bracket.
