Reverser mechanism for an automatic winding arrangement

摘要

In this reverser mechanism the winding wheel is assembled on a common axis with two ratchet wheels each assigned to one of the pivoting direction of the oscillating mass. The winding wheel is pierced by rivets which bear respectively a pawl and a spring. The spring which is thus mounted on a pivot means of a pawl cooperating with one of the ratchet wheels loads the pawl which cooperates with the other ratchet wheel. The mechanism is for use with timepieces having automatic winding of the mainspring.
