The typical carabiner has a gate that opens inward, which makes it easy to snap a rope through the gate, or to snap the gate over a rope. This 1906 link has a gate that opens outward, and don't ask me why. Other than the gate opening outward, this design looks pretty much like a modern carabiner. The gate has a spring that locks the gate shut until the user presses the release, much like a lock back knife. Pretty ingenious!
I wonder how many mountaineers fell after their outward opening carabiners failed?

I doubt this was used by mountaineers, but maybe by other users of rope, like sailors and yatch people. It does make you wonder why they had the gate opening outward though. Bob

The gates on these snaps open out rather than in to allow for maximum opening area (larger mouth opening)when attaching rope and webbing.

Does anyone know where I can get a full history for the carabiner?

Do you know exactly where the carabiner was invented?
