[SEL] "Free wheel, Locked wheel"

[MaytagTwin at aol.com]

Hi Rick,
If you were running a lineshaft, or, wanted to start an engine without load, 
you could shift the belt to the free wheeling pulley.  Then, when you were 
ready to run and the belt is moving, take a stick of wood and push the belt 
sideways onto the drive wheel.  The freewheeling pulley allows you to shut down the 
machine without stopping the power source.

Howdy all;
  We don't know why, but several of our pump jacks and water pumps (F-M 
"typhoon") have 2 belt pulleys next to each other.  One is free wheeling and 
the other is locked to the shaft.  We believe they called this arrangement 
"free wheel, Locked wheel".
  Can anyone explain why they did this arrangement?

TIA
