Abstract
Abstract This invention relates to a corrector mechanism for day and date watches. This mechanism, object of the present invention, consists in particular in a sliding lever, on which pivots freely a corrector star which is in mesh with a corrector, whereby the latter is located coaxially to the aforesaid sliding lever. Another particularity of this mechanism is, that the corrector is susceptible of being operated from the outside of the watch and that the whole mechanism is disposed in a manner that the corrector moves the sliding lever in the one or the other direction, according to the direction of rotation of the windingshaft, to bring the corrector star in gear either with the date indicator or the day indicator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A corrector mechanism for day and date watch, characterized by a rotatable lever (14) on which pivots freely a corrector star (17) which is in gear with a corrector (11) located coaxially to said rotatable lever (14), said corrector (11) being susceptible of being operated by a winding-shaft from the outside of the watch, the whole mechanism being disposed in a manner that, depending on the direction of rotation of the winding-shaft the corrector (11) moves the rotatable lever (14) in the one or the other direction and brings the corrector star (17) in mesh either with the date indicator (21) or with the day indicator (22).
Claim 2
Dependent Claim
107 words
A corrector mechanism for day and date watch, characterized by a rotatable lever (14) on which pivots freely a corrector star (17) which is in gear with a corrector (11) located coaxially to said rotatable lever (14), said corrector (11) being susceptible of being operated by a winding-shaft from the outside of the watch, the whole mechanism being disposed in a manner that, depending on the direction of rotation of the winding-shaft the corrector (11) moves the rotatable lever (14) in the one or the other direction and brings the corrector star (17) in mesh either with the date indicator (21) or with the day indicator (22).
Claim 3
Dependent Claim
20 words
Mechanism according to claim 1 characterized in that the corrector (11) presents several teeth (12) with a shape of lobes.
Claim 4
Dependent Claim
29 words
Mechanism according to claim 1 characterized in that the corrector (11) presents a shoulder (13) on which is adjusted with friction fit, like a regulator, the rotatable lever (14).
Claim 5
Dependent Claim
39 words
Mechanism according to claim 1, characterized in that the axis (16) of the corrector star (17) is engaged in two entries (18) of the frame, in a manner to limit the amplitude of moving of the rotatable lever (14).
Claim 6
Dependent Claim
54 words
Mechanism according to claim 1, characterized in that a metal foil (2) is located between the corrector star (17) and the frame in view to avoid that, during the working of the watch, the corrector star (17) enters inopportunely in gear with the date indicator (21) or the wheel (22) for the day indication.
Claim 7
Dependent Claim
38 words
Mechanism according to claim 1, characterized in that the corrector (11) is rigid with a corrector pinion (9) engaged in rotation by a corrector setting wheel (8), this latter being susceptible to be operated by the winding-shaft (1).
