No practical use Peter?

Yes it had. In the final drive (diff) on some older cars & lorries.
Commonly called "Worm and Wheel".

I believe that you can reverse drive a worm under certain circumstances. 
From memory, you must have a very 'fast' worm i.e a big pitch, and the 
correct angles of the worm and the gear. It will then reverse drive but is 
horribly inefficient, and is of little (if any) practical use.
