Winding Machine, Balanced Weights and Calculations
A pivoted-wheel mechanism with weights in equilibrium and inverted arithmetic
A working sheet of mechanical studies dominated by a central winding device, whose note explains that the 'female' part sits on the upper side and that the pole of the wheel is its pivoted centre. Gear, screw and pulley assemblies are sketched at the left in pen and red chalk. Three weights are set in balance at the lower right as 5, 10 and 10, and columns of arithmetic are jotted upside-down in the upper corner. The scholarly tags span geometry-and-algebra, instruments-and-machines and applied architecture.

Winding mechanism with a pivoted wheel
A note on the central device states that the 'female' part lies on the upper side and that the pole of the wheel serves as its pivoted centre. The drawing shows a horizontal frame carrying rods and cords drawn taut over a wheel. Gear, screw and pulley assemblies are sketched alongside it at the left.
Three weights in equilibrium
At the lower right three weights are noted in balance as 5, 10 and 10. They accompany the lever-and-cord scheme, testing how a load is distributed across the mechanism.
Inverted calculations
In the upper right corner, written upside-down, are columns of figures including 83 and 83 and a short division. They are working arithmetic jotted apart from the mechanical notes.
