The King Pivot Screw was a very interesting design… it was a long screw with a nut on the end.  What this allowed was to be able to take the list motion out of a pivot screw key an lock the washer against the post so it would not move.

Other pivot crews can work their way out creating lost motion in the key… this King Pivot crew was much more likely to stay in place.

Here you can see the screw as it is normally in the key and post.

This photo show that the nut can be moved almost to the end of the pivot screw to remove the lost motion.  It would never be screwed down this far but this is just to show the the great range of the screw and nut working together.
