Hi Curt,
That sounds like a machinist's version of a Chinese windlass, also called  
the differential windlass which is a simple but powerful means of increasing  
leverage.

Here is  a brain teaser. You've seen turnbuckles that use a RH and a LH 
thread? Try  making a turnbuckle with both RH threads but make one side 
with course  threads and the other side with fine threads. The mechanical 
advantage is  staggering and you'll be able to really put a tight cinch 
on something.  Far more effective than a standard RH/LH turnbuckle.
