Machine studies: rollers and a counterweighted frame
Two mounted fragments of mechanical drawings; the sheets bear diagrams but no writing
The leaf holds two pasted fragments, each carrying mechanical drawings but, as the notes record, no text. The upper fragment shows a device of paired cylindrical rollers set in a frame on a raised block, with smaller boxed and clamp-like parts sketched alongside. The lower fragment shows a tall timber frame whose horizontal beam carries weights suspended on cords over a large wheel-and-loop mechanism.

Rollers and small mechanisms on a raised stand
The upper fragment shows a machine whose paired cylindrical rollers are carried in a frame mounted on a masonry block, with an inclined panel beneath. Smaller components, including a boxed mechanism and clamp-like parts, are drawn to the left. No writing accompanies the drawing.
Beam machine with suspended counterweights
The lower fragment shows a tall timber frame carrying a horizontal beam whose outstretched arms hold weights hung on cords. A large wheel or looped structure fills the frame, and a coiled element trails from the base. The sheet carries no text.
