Maybe to seal the speed recorder box.

Most of the speed recorders had a vertical rod that dropped into the speed 
recorder box as the speed increased. If the rod didn't descend to correspond 
to the excess speed, there was no written record of the speeding event on 
the recording paper.

Engineers had lots of ideas for this engineering oversight. The slickest 
solution to this was a small piece of barstock with a hole drilled out to 
the diameter of the speed recorder rod. A machine set screw was located 
perpindicular to the rod's axis so that when it was screwed tight it would 
prevent the rod from descending into the speed recorder and you would always 
be within speed limits, at least on paper.

But to get to the rod, you had to break a seal if it was installed. Nobody 
really checked to verify if it was a wire seal or a car seal when it was 
last sealed. Just have it sealed when you hit the platform or diesel pit in 
case someone was looking.

If you were the outbound crew and it was supposed to be sealed and wasn't, 
you were to report it and have it sealed.

Maybe someone can remember whether or not it was connected to the throttle 
or the air. Don't remember. But I've seen them used on the speed recorders.

Just an idea.
