Abstract
Abstract A time-piece with a calendar indicator, comprising a rocking bar oscillating in a plane perpendicular to the clockwork, coaxially with the driving shaft, a function of which is to reset time, this rocking bar carrying a pinion constantly in mesh with a pinion born by the shaft and being driven by a push-piece which permits moving it against the action of a return spring, in a position wherein its pinion meshes with a contrate gear of the calendar indicator in such a manner that, when pressure is applied to the push-piece, the working of the driving shaft permits the indicator to rotate in one or the other direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
Time-piece with a calendar indicator, a calendar setting device comprising a rocking bar oscillating in a plane perpendicular to the clockwork, coaxially with the driving shaft a function of which is to reset time, this rocking bar carrying a pinion constantly in mesh with a pinion born by said shaft, said rocking bar being driven by a push-piece which permits moving it against the action of a return spring, in a position wherein its pinion meshes with a contrate gear of the calendar indicator, the whole in such a manner that, when pressure is applied to said push-piece, the rotation of the driving shaft permits making said indicator rotate in one or the other direction.
Claim 2
Dependent Claim
115 words
Time-piece with a calendar indicator, a calendar setting device comprising a rocking bar oscillating in a plane perpendicular to the clockwork, coaxially with the driving shaft a function of which is to reset time, this rocking bar carrying a pinion constantly in mesh with a pinion born by said shaft, said rocking bar being driven by a push-piece which permits moving it against the action of a return spring, in a position wherein its pinion meshes with a contrate gear of the calendar indicator, the whole in such a manner that, when pressure is applied to said push-piece, the rotation of the driving shaft permits making said indicator rotate in one or the other direction.
Claim 3
Dependent Claim
66 words
Time-piece as of claim 1, wherein said shaft serves to wind up the watch when being in the push-in position and to reset time when being in the pulled-out position, characterized by the fact that the pinion carried by the rocking bar meshes constantly with the winding-pinion so that the calendar indicator can be driven by said shaft when the latter is in its winding position.
Claim 4
Dependent Claim
29 words
Time-piece as of claim 1, having chronograph indicating devices, characterized by the fact that said push-piece is represented by the push-piece for setting the chronograph hands back to zero.
Claim 5
Dependent Claim
34 words
Time-piece as of claim 3, characterized by the fact that the moving of said rocking bar is controlled By said push-piece through the medium of the lever for resetting the chronograph hands to zero.
Claim 6
Dependent Claim
87 words
Time-piece as of claim 4, characterized by the fact that said rocking bar is provided with a perpendicularly bent portion, located essentially in a radial plane with regard to the clock-work, an edge of which is diagonally inclined with respect to the plane of the clock-work, the lever used for zero reset being provided with a lug that cooperates with said slant plane so that, when being displaced under the action of said push-piece, it makes said rocking bar tilt by working against the inclined plane thereof.
