Abstract

The profiled element (1) has three equal major faces, separated from each other by an edge face (2), and is machined by turning, to form the two pivot pins (8) for the shaft, a slot (5) for attachment of the end of the spiral balance spring, a bearing surface (3) for the balance wheel (4) and a conical tapered section (7) acted on by a retarding roller. The three major faces of the profile (1) may each be concave, with the edge faces (2) being planar or slightly convex. The profile may alternatively have two concave major surfaces, and two smaller convex edge faces.
