Wheel for Perpetual Motion
A disk of radial spokes carrying weighted balls, hung from an overhead bar by cords.
The upper part of the page carries a single ink drawing, catalogued as a wheel for perpetual motion, above an otherwise blank leaf. A circular disk is divided by many radial spokes running to a central hub, with small balls or weights set around its rim and along the spokes. Cords descend from a horizontal bar at the top of the sheet toward the wheel, suggesting the weights are meant to swing outward and drive the wheel around. No transcribed text accompanies the figure.

Radial-spoke wheel with rim weights
The drawing shows a circular wheel whose many spokes radiate from a central hub, each carrying small round weights toward the rim. A horizontal bar above the wheel sends down cords toward the weighted arms. The arrangement is the classic form of an overbalancing weight-wheel intended to keep itself turning.
