Mr. Pie, Hansen received a patent just for numbering the points on a star drag that precluded other from doing the same?!? Seriously?
Please, Anon, give the guy some credit. Here's just one of the eight lengthy claims:
"In a fishing reel, a spool, a shaft, a friction brake on said shaft and adapted to exert a dragging force on said spool, said brake including a disk fast on the shaft and having a single abutment on its periphery, a stop pin cooperating with said abutment for preventing rotation of said disk and shaft in one direction, means for varying the dragging force of said friction brake which includes a pin movable longitudinally in said shaft, and an adjustable nut threaded on said shaft and capable of but one complete revolution, said nut having consecutively numbered indicating arms."
That last phrase, repeated in a couple other claims, is The Great Precluder

, but the other things - pins, abutments, etal. - are also precluders. And that's only one claim. Precluders abound in the patent.
