Lever Hoist for Raising a Weighted Box
A long beam and derrick lift a heavy load, with five small geometric figures above
The sheet is filled by a lifting machine drawn in elevation: at the left a trestle-derrick with a pulley at its apex suspends a weighted box on ropes, and a long beam runs across to a tall crate-like structure at the right. Along the top are five small geometric figures marked with measures such as 4 and 8, and a few numbers are jotted below. The transcription preserves only these figure-labels and numerals; the mechanism itself is drawn, not described in words.

Beam-and-derrick hoist lifting a box
A trestle-derrick with a pulley at its apex suspends a weighted box on ropes at the left, while a long horizontal beam carries the load across to a tall crate-like structure at the right — a hoisting apparatus for raising a heavy weight.
Long beam worked as a lever over the load
The long horizontal beam pivoting over the derrick acts as a lever, balancing the suspended box against the mechanism at the far end.
Five small geometric figures with measures
Along the top are five small geometric figures annotated with paired measures such as 4 and 8 (and a fraction, 4 and 1/2), set out as a short series.
Jotted numbers below the machine
A few figures — 3 6, 3 8, 1 6 — are jotted below the drawing, with a broken-off word.
