[57] ABSTRACT A time-piece with a calendar indicator. comprising a rocking bar oscillating in a plane perpendicular to the clockwork, coaxially with the driving shah. 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 pushpiece which permits moving it against the action of a return spring, in a position wherein its pinion meshes with a oontrate gear of the calendar indicator in such a manner that. when pressure is applied to the push-piece, the working of the driving ahafl permits the indicator to rotate in one or the other direction.
SCIIInBJIh-aflngHgures PKTE'N'TEDJUL 1 1 1912 INVENTOR. Paul Louis NOUQU/IV Jean BUG/VON The present invention concerns a time-piece with a calendar indicator.
This time-piece is characterized by the fact that is comprises 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 shah; 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, the whole in such a manner that, when pressure is applied to said push-piece, the working of the driving shaft permits making said indicator rotate in one or the other direction.
As an Example, the drawing represents one particular embodiment of the invention.
FIG. I is a plan view, bottom side, of a portion of a chronograph-watch with a calendar indicator, part of the plate having been torn off for showing the parts below, and
FIG. 2 is a sectional view thereof along the line Il-Il of FIG. I.
The frame structure of the watch represented here comprises a bottom plate 1 carrying a shalt 2 for winding up and resetting time. The winding and reset mechanism is of a common type with a clutch-wheel 3, yoke 4 and setting-lever 5, the latter being retained by a jumper-spring represented by the elastic arm 60 of a barrette 6 attached to the bottom plate I by means of two screws 7. The crown-wheel, which meshes with the contrate teeth of the clutch-wheel when the shaft 2 is in a pulled out position, is indicated by 8, whereas the windingpinion, carried by shaft 2 and driven by clutch-wheel 3, whenever shaft 2 is in the pushed winding up position, shown on the drawing, is indicated by 9.
The chronograph mechanism, of which only the parts required for comprehending the invention have been represented, comprises a push piece 10 working against a lug 1 la of a rocking bar 1] driving the column wheel and a pushpiece 12 working against a lug 13a of a rocking bar 13 for resetting the chronograph hands back to zero, a spring common to both bars, resting on a pin I5 carried by the bottom plate 1, acting over both rocking bars II and I3 and, as a consequence, over both push-pieces l0 and 12 to draw them back to their rest point.
The watch described here comprises a crown shaped wheel 16 carrying the calendar indicator, partly displayed on FIG. 2 and deleted on FIG. 1 to improve the clarity of the drawing. This crown I6 is provided with an inside toothing, not visible on the drawing, by means of which it is driven at the rate of one tooth for every 24 hours, by the clockwork, and a contrate toothing 16a for rotating it rapidly and resetting the date.
For this purpose, the watch represented here comprises a rocking bar 17, called the correction-bar, rocking in a plane perpendicular to the plane of the clockwork and hinged over a bearing 2a of the shaft 2. This correction-bar carries, cranked onto it in 18, a pinion l9 constantly in gear with the windingpinion 9 and capable of meshing with the contrate toothing 16a of the crown 16. The correcting bar 17 is provided with an elastic extension arm 17a, resting under the bottom plate I, for returning it to the position shown on the drawing wherein its pinion I9 is not in gear with the toothing 16a of the crown 16 carrying the calendar indicator.
This bar 17 is further provided with an arm 17b ended by a right-angle portion 17c, located essentially in a radial plane with regard to the clockwork, on which has been managed a diagonally cut plane 20 which can cooperate with a lug 13a of the rocking bar 13 used for zero reset.
It results from this arrangement that when a push is given to push-piece l2, displacing the rocking bar 13 in the direction shown by the arrow 21 on FIG. 1, the lug 13a of this rocking bar, sliding against the diagonally cut plane 20 of the portion 17c of the rocking bar 17, tends to rotate the latter in the direction of the arrow of FIG. 2, leading the inion 19 of this rocklng bar to mesh wlth the contrate too ing 16a of the crown carrying the calendar indicator. It the shaft 2 staying in its pushed-in winding position is being acted upon simultaneously when a push is exerted on push-piece II, the winding pinion 9 ensures the early driving of the crown 16 carrying the calendar indicator in one or the other direction, depending on which way the shaft 2 is rotated.
It should be noticed that this function is made possible by the fact that the mainspring of the watch described here, which has not been represented, comprises a slip-spring, the presence of which makes possible the operation of shaft 2 even when the watch is fully wound up.
It should also be noticed that the present arrangement could also fit an electric watch wherein the driving shaft 2 would only be used for time resetting in the pulled-out position and for resetting the date in the pushed in position. An accidental unsetting of the crown carrying the calendar indicator should not be feared, since push-piece l2 and shalt 2 should be operated simultaneously for having the crown 16 be driven.
Finally, although in the Example represented the push-piece 12 is for resetting the indicating devices of the chronograph back to zero, it could also have the unique function of driving the rocking bar 17, this in the case when the watch is not a chronograph.
What we claim is:
l. 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 sprin 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.
2. Tirne-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 shafi when the latter is in its winding position.
3. Time-piece as of claim I, 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.
4. 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.
5. 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.
