Thanks for posting that. It appears as though there was not a clutch on
the overhead pulley. Meaning that spindle speed changes were done
"hot". I.e., with the belt running. The good old days.


How else? The overhead shaft system was driven by some outside power
source and adding a clutch to each and every machine station would
cost a fortune and operators learned how to change speeds without
losing a finger. You certainly didn't use your hands to move the belt.
