Mechanical device on a vertical shaft
Pen sketch of a geared mechanism with arms and counterweights
In pen Leonardo sketches a mechanical device organised around a tall vertical shaft or column. Horizontal arms and levers branch from a small toothed wheel at mid-height, ending in what appear to be counterweights and jointed fittings. A separate smaller detail is drawn at the lower right. The page carries no transcribed text.

Shaft with geared hub, arms and counterweights
A vertical shaft rises through a small toothed wheel or hub from which horizontal arms extend to either side. The arms terminate in weighted or jointed fittings, and a smaller companion sketch at the right repeats one of the details. The mechanism is drawn in pen without accompanying notes.
