Herringbone Pinion Gears

These herringbone gears were part of updating my old Thing-O-Matic:

Herringbone gears with nut inserts

But, as the saying goes, that’s not a herringbone gear. This is a herringbone gear:

Bethlehem Steel - 48 inch rolling mill gears

We always read the signage:

Bethlehem Steel - 48 inch rolling mill gears - description

They’re parked in front of the National Museum of Industrial History in Bethlehem, PA.

    Beth made some huge wide-flange beams, much bigger than Inland Steel could do. Had to order one for a job when I was interning, and the thing wouldn’t fit on a truck; so it got its very own rail car. Not sure of the size, IIRC it was both too long and too heavy to transport by truck over the Interstate. No idea how they got it to the jobsite.

      Probably rolled by those very gears!
