Abstract
Abstract A calendar timepiece, with indicators of the days of the week and of the dates, comprising a control stem capable of disposition in at least two axial positions, in one of which positions it permits the setting of the timepiece and in the other of which positions it permits the correction of the days and dates indicators, the control stem in the last-named position being connected to one of the indicators of the dates and of the days so that it operates in the two directions, a one-way coupling mechanism being interposed between these two indicators in such a way that, in one direction of rotation of the stem, only one of the indicators is driven while, in the other direction of rotation of the stem, the two indicators are driven, one being driven by the other through the intermediary of the coupling mechanism.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
In a calendar timepiece with indicators of the date and of the day of the week, the improvement comprising: a rotatable control stem shiftable between a first position for allowing the setting of the timepiece and a second position for allowing the correction of the date and day indicators, a one-way coupling mechanism interposed between the two indicators, the control stem in the second position being connected to one of the indicators for selective operation in opposite direction of rotation with one of the indicators being driven during control stem rotation in one direction and with the two indicators being driven during control stem rotation in the opposite direction through the intermediary of the coupling mechanism, a pawl carried by the day indicator and a ratcheted toothing carried by the date indicator and cooperant with the pawl with an angular play therebetween.
Claim 2
Dependent Claim
142 words
In a calendar timepiece with indicators of the date and of the day of the week, the improvement comprising: a rotatable control stem shiftable between a first position for allowing the setting of the timepiece and a second position for allowing the correction of the date and day indicators, a one-way coupling mechanism interposed between the two indicators, the control stem in the second position being connected to one of the indicators for selective operation in opposite direction of rotation with one of the indicators being driven during control stem rotation in one direction and with the two indicators being driven during control stem rotation in the opposite direction through the intermediary of the coupling mechanism, a pawl carried by the day indicator and a ratcheted toothing carried by the date indicator and cooperant with the pawl with an angular play therebetween.
Claim 3
Dependent Claim
35 words
In a calendar timepiece as set forth in claim 1 including: the ratcheted toothing of the date indicator comprising 31 teeth equal to the number of teeth of a driving toothing of the day indicator.
Claim 4
Dependent Claim
31 words
In the calendar timepiece as set forth in claim 1 including: a disc coaxial and angularly rigid with the day indicator, the pawl comprising a blade cut at the disc periphery.
Claim 5
Dependent Claim
44 words
Timepiece as claimed in claim 1, characterized in that the coupling mechanism comprises an intermediary wheel driven, at least indirectly, by the toothing of the date indicator, this intermediary wheel carrying at least one driving element cooperating with a toothing of the daY indicator.
Claim 6
Dependent Claim
39 words
Timepiece as claimed in claim 4 characterized by the intermediary wheel being driven by the date indicator by means of an intermediary pinion so that the days indicator is driven by and in the direction of the date indicator.
Claim 7
Dependent Claim
21 words
Timepiece as claimed in claim 4 characterized by the driving element being constituted by a pawl carried by the intermediary wheel.
Claim 8
Dependent Claim
25 words
Timepiece as claimed in claim 6 characterized by the intermediary wheel carrying two diametrically opposed pawls for operating the day indicator twice per each revolution.
Claim 9
Dependent Claim
21 words
Timepiece as claimed in claim 4 characterized by the driving element being constituted by a wheel rigid with the intermediary wheel.
Claim 10
Dependent Claim
87 words
Timepiece as claimed in claim 8, the axis of the intermediary wheel being situated beyond the radius passing through the middle of the free space between two teeth of the wheel driven by the wheel rigid with the intermediary wheel situated opposite this axis so that, in one direction of rotation of the intermediary wheel, one of the indicators be driven on a value not sufficient to that a jumper acting thereon achieves its movement and rotates it, while in the opposite direction this function is effected.
Claim 11
Dependent Claim
39 words
Timepiece as claimed in claim 8, an asymmetrical jumper acting on the indicator with which cooperates the wheel rigid with the intermediary wheel so that the jumper achieves the movement of the indicator in only one direction of rotation.
