treadles
Loom leg-powered parts
Treadles are foot-operated levers that power machinery through a rocking motion.
The operator presses down repeatedly, converting leg movement into rotational energy.
Sewing machines, pottery wheels, and looms traditionally used treadles before electric motors became standard.
The verb means to work such a lever: She treadled steadily as the wheel spun.
