Here's my recollection of those dropouts: as Jan suggests, those inserts are threaded. What kept them from rotating is that they were a relatively tight fit. I don't recall any extra ribs, splines or keyways.

If my recollection on this is faulty, please let me know.

By the way, there are also Simplex dropouts that use a plastic insert. In this case, though, the insert is cylindrical and fits in a hole drilled behind the axle slot. Cheers, Fred Rednor - Arlington, Virginia
