Yep.... There is supposed to be a hand wheel to tighten the bolt to pull a "lip" (or tab) on underside of the coupler to clamp the ball.... The hand wheel is missing on one in pic....
There was another version that had a lever and a eccentric that when pressed down the eccentric pulled the bolt up to tighten lip under ball...
Which ever system it was, some parts are long gone as you can tell....
