Herringbone. In the mechanical world often encountered as a gear pattern, especially where extreme strength is needed because you get more gear-tooth surface contact area than with simple spur design. Commonly used in high speed steam turbine reduction gears where it had the added advantage of limiting fore-to-aft movement of the gear members. Somewhere I had a photo of the herringbone turbine reduction gears from the WW II battleship Massachussetts (BB59). I'll see if I can find it.
