Barrel arbor (In French: arbre de barillet)

Supports the barrel and its spring. It comprises a cylinder and a hook to which the inner end of the mainspring is attached. The upper pivot is cut into a square for the ratchet-wheel. The arbor moves in holes, one in the plate and the other in the barrel bridge.
