My family had one almost identical to it when I was a kid. The mechanism probably needs service. Like any clockworks, cleaning, lubrication is required. Also, the governors tend to break on these. That may be what fell out and the spring may new be weak and need replacement. The newer springs are made of better grade of alloyed steel and don't break or weaken like the old ones.
