[TR] Free Wheel Def

I am thinking that this is something akin to what SAAB was using in the 60's
and perhaps before.  
There is a shaft that turns within a hub with roller bearings and ramps for
the bearings to spin on within the hub.

The shaft would be connected to the transmission and the hub would be
connected to the engine.  If the engine RPMs are higher than the
transmission shaft, the shaft would lock inside the hub causing both units
to be turning at the same speed.  But if the transmission side is spinning
faster than the engine, the shaft spins freely inside the hub.

The result is you don't get engine braking and you can shift gears up and
down without the clutch.

This device could be disengaged so that the engine and transmission work the
same as what we are used to.

I think I got this right.  It has been way too many years and I had to think
very hard to recall the dynamics of it all.

     I am looking through a book on British cars of 1947 and it makes
mention
that some cars have a "free wheel".  I've seen this term before. What does
it
mean?
