Historical Escapement Mechanism Diagram - Engineering & Horology Reference #1767376 (License: Personal Use)

This black-and-white technical illustration depicts a traditional verge escapement, featuring a central escape wheel with pointed teeth engaging two pallets (A and B) attached to a foliot or balance staff. The upper pivot point (C) represents the impulse jewel, while points D, E, F, and G denote critical contact and reset positions during oscillation. The arrow indicates the direction of rotational force transmission from the mainspring via the gear train.
