Screw and framework mechanisms with load studies
Pen studies of screws, frames and trestles, headed by untranscribed mirror-script
Several lines of mirror-script head the sheet; this writing is not included in the bundle and is not reproduced here, but the reader should note that further untranscribed text is present. Below it, in pen, are studies of mechanical members: a long vertical toothed screw or rack, a rectangular frame enclosing a shaded panel, a low roller-ended bed marked 34, and trestle-like supports, with a small crenellated wall drawn in perspective at lower right. The drawings read as components of screw- and frame-based lifting or load-bearing apparatus.

Screw, frame and trestle studies
A tall vertical member drawn as a close-toothed screw or rack dominates the centre. Around it are a rectangular frame enclosing a hatched panel, a low horizontal bed with cylindrical rollers at each end (marked 34), and trestle-like supports above. Together they read as parts of a screw-driven lifting or pressing device.
Untranscribed heading; load-bearing frames
Several lines of mirror-script head the sheet. This writing is not included in the bundle and is not reproduced here; the reader is alerted only that further untranscribed text is present. The framed and braced structures drawn below study members arranged to carry loads.
