Here is a photo of the mechanism as it appears in HP-14T blue-prints.

This hook has been very reliable for the past 50+ years. The concept has been
copied and install on other sailplane designs including the 1-35A

And also - at least conceptually/functionally - George Applebay's Zuni design
(though some may now/have-had Tost releases); I can't speak for
dimensionally/geometrically. Difficult (for me) to imagine a simpler release
mechanism.

I never had release a release problem in 106 HP-14 and 655 Zuni aerotows. Had
1-each back release in both ships, from BIG bows in the rope...as should have
happened.
