[SEL] Speed limiter

[Steve Gray]

Hey Guys & Gals -

   I picked up a little trinket last November in the form of a speed 
limiter for a line shaft. At first, I thought if might be an early form 
of a centrifugal clutch until I saw how the flyballs were pinned. The 
large pulley in the pictures would have been the driven (input) side 
which spins the clutch drum. The clutch shoes, which are wood, are 
mounted on the flyballs and are spring loaded against the drum. This 
transmits the rotating motion from the input pulley to the output shaft 
and pulley. If the speed becomes too great, the flyballs pull the clutch 
shoes away from the drum, slowing the output. This unit has no markings 
whatsoever other than having a lot of old red paint on it. Any idea of 
age and maker? Pictures are at: http://www.oldengineshed.com/snapshot/. 
I need to pour new babbitt bearings in it, but it's in excellent shape, 
otherwise. If there's room for it, it might end up on the big display 
trailer.
