[SEL] "Free wheel, Locked wheel"

[Tod Engine]

You move the belt to the free wheel when you want to disengage the pump but 
keep the power source running.  Then to engage the pump move the belt to the 
locked wheel (called that becasue its "locked" to the driveshaft) and the 
pump starts up.

Its used extensively in overhead line shafted machine shops.
