Studies of a geared mechanism with levers and a bench
Perspective and detail views of a lever-and-gear device built around a large boxed frame
The sheet is filled with drawings of a built mechanism shown in perspective and in separate detail views: a large boxed frame or bench carries jointed levers, brackets and small toothed and drum-shaped parts, with a coiled or barrel element at lower left. The only transcribed note simply locates a jotting in the lower-left corner, so the device is documented here from the drawing alone; further untranscribed writing is faintly visible along the right margin.

Lever-and-gear device on a boxed frame
A large rectangular frame or bench is drawn in perspective at the centre, with articulated levers and brackets ranged around it and smaller toothed and drum-like components shown separately. The parts are repeated in several orientations as though to work out how the linkage moves.
