A balance with two poles and other small mechanisms
A girth, a pulling linkage, and a house with three terraces
Rotated ninety degrees, this sheet gathers small mechanical sketches with brief captions: a house with three terraces, labels of millet and panic-grass 'for the birds and likewise for the water', a girth or strap, and a balance with two poles. Beneath the balance Leonardo notes that though loaded with excess weight it behaves like a common balance, since one pound at d raises six at f. Another caption describes a linkage in which pulling a b by one braccio moves b to n and e to m. The sheet carries further sketched mechanical detail beyond what is transcribed.

A balance with two pivots
The two poles are loaded with excess weight, yet in other respects the device behaves like a common balance: if one pound at d raises six at f, then six at a raises one at c, and it balances out.
A pulling linkage a b, b to n, e to m
A lettered figure with the note that if a b pulls by one braccio, then b comes to n and e comes to m, describing the coupled displacement of a strap-and-lever mechanism.
A house with three terraces
Along the top margin a small building is sketched and labelled a house with three terraces.
