Dave , my apologies. I apparently used the wrong terminology.
Below I have posted several photographs showing the bolt/ rib extension interface. Looking at the Lefever catalog drawings , which I have and you posted, it is easy to assume that the locking bolt moves longitudinally and engaged a bite or notch in the rib extension , like a Parker. I certainly do not claim to have seen all Lefevers and I admit to having closely studied less than 15 or 20. Of those , none have a bolt that simply moves longitudinally. I used the term "rotate" to describe the movement and perhaps that was in error.
The below series of photos show the bolt/bite interface . We will start with the rib extension. Note that it is angled . The angle of 15 degrees in combination with the bolt provides self compensation.
