Abstract
Abstract A timepiece comprising a control stem manually operable, capable of occupying at least two axial positions, characterized by the fact that it comprises a toothed rotatable member, operable by the stem in a first axial position thereof, and a set of control mechanism intended to execute different operations, comprising each a lever capable of occupying two positions, i.e. a rest position and a working position in which a wheel carried by the lever meshes with the toothing of the rotative member coaxial to the movement, a rotatable selecting member, controlled by the stem when it occupies a second axial position, whereby one or the other of the said control mechanism is brought selectively in its working position in which it operates when the stem, brought back in its first axial position, is operated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
Timepiece comprising a control stem manually operable, able to occupy at least two axial positions, a movement, a toothed rotatable member coaxial to the movement operable by the said stem in a first axial position thereof, and a set of control mechanisms intended to execute different operations, each comprising a lever able to occupy two positions, i.e. a rest position and a working position in which a wheel carried by the said lever is meshed with the toothing of the said rotatable member, a rotatable selecting member controlled by the said stem when it occupies a second axial position in which it brings selectively one of the said control mechanisms to its working position in which it operates when the stem, brought back in its first axial position, is operated.
Claim 2
Dependent Claim
130 words
Timepiece comprising a control stem manually operable, able to occupy at least two axial positions, a movement, a toothed rotatable member coaxial to the movement operable by the said stem in a first axial position thereof, and a set of control mechanisms intended to execute different operations, each comprising a lever able to occupy two positions, i.e. a rest position and a working position in which a wheel carried by the said lever is meshed with the toothing of the said rotatable member, a rotatable selecting member controlled by the said stem when it occupies a second axial position in which it brings selectively one of the said control mechanisms to its working position in which it operates when the stem, brought back in its first axial position, is operated.
Claim 3
Dependent Claim
67 words
Timepiece as claimed in claim 1, characterized by the fact that the rotatable selecting member is constituted by a ring coaxial to the movement, provided with a toothing meshing with a pinion carried by the control stem, this ring being provided with at least one recess which, when it is opposite a control mechanism, authorizes the movement of the lever of this mechanism to its working position.
Claim 4
Dependent Claim
35 words
Timepiece as claimed in claim 1, characterized by the fact that the said toothed rotatable member meshes with an intermediate wheel with which cooperates the toothing of a sliding pinion carried by the said stem.
Claim 5
Dependent Claim
45 words
Timepiece as claimed in claim 1, characterized by the fact that one of the control mechanisms comprises a star-wheel rigid with a wheel meshing with the wheel controlled by the toothed rotatable member, this star-wheel cooperating with the inner toothing of a date indicating crown.
Claim 6
Dependent Claim
55 words
Timepiece as claimed in claim 1, characterized by the fact that one of the control mechanisms comprises a pinion rigid with the wheel controlled by the toothed rotatable member and which is meshing with a wheel rigid with a pinion which meshes with the wheel of the motion-work, that permits the setting of the timepiece.
Claim 7
Dependent Claim
56 words
Timepiece as claimed in claim 1, characterized by the fact that one of the control mechanisms comprises a wheel meshing with the wheel controlled by the toothed rotatable member, this wheel meshing with a supplementary hour wheel carrying a universal hour hand, in view of the setting of the position of this supplementary universal hour hand.
Claim 8
Dependent Claim
57 words
Timepiece as claimed in claim 1, characterized by the fact that the said selecting member carries, on its upper face, indications relating to the several operations which are controlled by the said control stem, these indications appearing successively in a window of the dial, so as to permit the operator to know what is the selected operation.
Claim 9
Dependent Claim
70 words
Timepiece as claimed in claim 1, characterized by the fact that it comprises a rotatable locking member, coaxial to the selecting member, controlled by the axial movements of the control stem, and which is able to occupy two positions, one in which it maintains the said control mechanisms in their rest position, and the other in which it authorizes these control mechanisms to be operated by the rotatable selecting member.
Claim 10
Dependent Claim
151 words
Timepiece as claimed in claim 8, characterized by the fact that the locking member is constituted by a ring coaxial to the selecting member, provided with a set of recesses able to be brought simultaneously opposite the several levers of the control mechanisms, when the said ring occupies its second position, the movements of the said ring from one position to the other one being produced by a two-arms-lever articulated on the movement, one arm of which is substantially radial and cooperates with the said ring for rotating it to the angular value which is necessary so that it passes from one of its working positions to the other, and the other arm of which is connected to a trigger-piece operated by the control stem, the whole in such a way that to each of the two axial positions of the stem corresponds an angular position of the said lOcking ring.
