๐๐ฉIn 1891, Clinton A. Higbee designed the modification to solve problems with sharp, feather-edged thread starts which easily jammed, shaved metal, or cross-threaded under fast-paced manual assembly.
He also held several more patents in the 1890s and early 1900s, mostly related to screw threads, couplings, and tools for creating the blunt-start (Higbee) thread.
The foundational one is the 1891 patent for the screw bolt and nut that introduced the Higbee cut.
The design quickly became a standard in the fire service industry for fire hose couplings.
Because firefighters need to connect hoses rapidly in emergency situations, a blunt start ensures the threads align smoothly on the first turn.
Many couplings feature visual markings showing the exact starting point of the Higbee cut.
The design was later adopted into official engineering standards, such as ASME B1.7 (defining it as a "blunt start thread") and ASME B1.2 for thread gaging.
The Problem: A standard cut thread ends in a thin, fragile "feather edge" or incomplete partial thread that catches easily and starts misaligned.
The Higbee: A portion of the incomplete or sharp starting (and sometimes ending) thread is removed... often using a grooving or parting tool on a lathe... which is what yours truly does on swiss lathes... to create a blunt, smooth lead-in edge.๐ช๐ฉ
One moonless night, while flying a routine training mission over the Pacific, I wondered what the sky would look like from 84,000 feet if the cockpit lighting were dark.
While heading home on a straight course, I slowly turned down all of the lighting, reducing the glare and revealing the night sky. Within seconds, I turned the lights back up, fearful that the jet would know and somehow punish me. But my desire to see the sky overruled my caution, I dimmed the lighting again.
To my amazement, I saw a bright light outside my window. As my eyes adjusted to the view, I realized that the brilliance was the broad expanse of the Milky Way, now a gleaming stripe across the sky. Where dark spaces in the sky had usually existed, there were now dense clusters of sparkling stars Shooting stars flashed across the canvas every few seconds. It was like a fireworks display with no sound. I knew I had to get my eyes back on the instruments, and reluctantly I brought my attention back inside.
To my surprise, with the cockpit lighting still off, I could see every gauge, lit by starlight. In the plane's mirrors, I could see the eerie shine of my gold spacesuit incandescently illuminated in a celestial glow. I stole one last glance out the window. Despite our speed, we seemed still before the heavens, humbled in the radiance of a much greater power.

Production Gamified, if it works it works lol.
