Hensley Arrow: How does it REALLY work?
There have been several discussions on this hitch that have become somewhat 'controversial'. I am NOT trying to stir this controversy/bashing back up. Instead, I'd like to see a good, intelligent di...

Well, I've got the ears in the wrong place. The restraint bar drops down into the hitch bar cavity when the hitch bar is NOT in place, and the other end of the restraint goes UP into the rear bar - one of 5 possible positions. This restraint appears to be of about 0.5 x 0.75 x 3" and has considerable clearance on the sides between the ears (Yes Burb, sort of like mine [just checking]). The ears themselves are similarly stout, and about 1.5" out to out. A roll pin serves as the pivot, but it's only tight in the ears. The restraint is wobbly. But in fact, it is the "stop" that causes the "thunk" we hear at the end of the tape.
One thing that's a bit confusing is that the drawings show the linkage from the TT point of view, but most of the time we're looking at the hitch on the front of the TT where it's always mounted, the TV being usually elsewhere and we're free to rotate the TV end as desired to see the action. But that means we're seeing the action from the TV viewpoint. As a result, it's the narrower 'front' bar we can manipulate to see the action. Now in my feeble brain that shouldn't make a great deal of difference, but maybe it really does.
From Center position to one side, one short link appears to rotate about 90 degrees and then returns toward it's original position at full deflection of the front bar. The other short link rotates over 180 degrees as the picture shows. Of course going the other way, the links switch roles.
Well now, I just had another look at Tim's drawing, and that's EXACTLY what he shows.
