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...

At no time does the side link opposite the direction of pivot cross over any of the other bars - well, outside the area around the two joints anyway.
LIB!
I am mistaken. The links DO pass each other. That's why they're shaped a little like a figure 8 - to provide clearance. This design is cleverer than I thought.
The thunk is also identified. Earlier I talked about the drop down gravity bar that holds the hitch straight when the hitch bar is not in place. That bar is held in place by a pin which is mounted in two ears on top of the black piece. At the limit of travel, one of the side links interferes with the nearest ear. The ears and the drop down bar are all pretty hunky, so the overall width of the 'stop' is about 1 1/2"
The fact that the links pass each other also explains the s-shaped locus of VPP's. Tonight I learned that the original creator of this design was very clever indeed.
Apologies for the earlier misinformation.
