The Bridges and Cocks



All the parts in the Movement are held together by the main Plate, Bridges and Cocks. The main Plate is the basis for the movement onto which all bridges and cocks are mounted. All the Wheels, the Barrel, and the Pallet Lever are held by a lower bearing in the Plate and an upper bearing in a Bridge or a Cock. A Bridge has two or more studs while a Cock just has one.



  In the figure above the Main Plate can be seen in the center. To the upper right is the Pallet Lever Cock and to the lower right is the Balance Cock. The Barrel Bridge can be seen up left and down right is the Wheel Train Bridge.



In the figure above all the Bridges and Cocks are put into their positions at the Main Plate.
