Odd question: can anyone help me find the original patents for kernmantle and/or dynamic ropes from back in the 50s and 60s? Even just the #s. I figured that they wouldn't be hard to track down, but, once again, I'm wrong.

Any tips or thoughts or help?

Edelrid is often cited as first introducing the first kernmantle rope (1953) in Germany. I believe this is just in a climbing sense though. Kernmantle ropes certainly predate the 50s.

Guideline #1: Don't be a jerk.
