Machine driven by a 10,000-pound counterweight
A framed mechanism the catalogue links to gold-beating or cloth-shearing
A tall framed machine stands on a widely splayed base, its upper crossbar carrying hooked links and pulleys while paired cylindrical drums sit within the frame around a central vertical post. At the foot a large box, inscribed as weighing 10,000 pounds, serves as the driving counterweight named in the note. The Ambrosiana catalogue associates the device with gold-beating (battiloro) and cloth-shearing (cimatrice) machinery.

Framed machine with drums and pulleys
A rectangular frame on a wide splayed base holds paired cylindrical drums, with hooked links and pulleys suspended from the top crossbar and a central vertical post descending to the base. The catalogue links the mechanism to gold-beating and cloth-shearing.
A 10,000-pound counterweight
The heavy box at the foot of the machine is marked as its counterweight, given as ten thousand pounds; its descent supplies the motive force that drives the mechanism.
