Mechanism with a wheel and rods
Red-chalk sketch of a hubbed wheel linked to rods with terminal fittings
In red chalk the page shows a mechanism built around a central wheel or disc on an axle, with rods running out to either side that end in hooked or T-shaped fittings, and small arrowheads set along them. The cataloguer labels it simply a 'mechanism.' Faint traces of mirror-written text appear at the upper right and are not included in the transcription.

Central wheel with lateral rods
A wheel or disc sits on an axle at the middle of the sketch, with straight rods extending left and right to terminal fittings. The layout reads as a linkage transmitting motion or pull across the hub.
Directional arrows on the linkage
Small arrowheads drawn on the rods appear to indicate the direction of motion or of the force carried through the mechanism.
