Hook-and-Pawl Mechanisms for Locks
Red-chalk studies of latching devices
Red-chalk sketches that the catalogue titles as hook-catch mechanisms (arpionismi) for locks. Two framed studies show angular pawl-and-arm assemblies mounted on wheeled or pivoting supports, with a lighter lever-and-wheel sketch above. No text accompanies the drawings on this page.

Latching hook-and-pawl assemblies
Two boxed drawings each show an angular, arrow-like pawl engaging against a wedged or toothed bar, carried on small wheels or a pivot. A fainter sketch at the top of the sheet repeats a lever pinned to a small wheel. The forms suit the catalogue's description of hook-catches for locks.
