When a user passes from one time-zone to another, for instance on travelling by plane, it is important to change the hour indication by one or more units. If the user actuates the setting mechanism, he loses the indication of the minute and of the second.
SUMMARY OF THE INVENTION A timepiece movement according to the invention comprises two identical, coaxially mounted, individually rotatable gears operatively connected with an hour hand of a timepiece with which the movement is associated. One of the gears is driven by the power train of the movement and the other of the gears is selectively operable manually by the usual winding stem to enable adjustment of the power hand according to the change of time zones. The gears are provided with magnetic means which normally couple the gears together for simultaneous rotation by the power train but permit manual adjustment of the one gear relative to the other to change the indication of the hour hand but without affecting, any other hands such as the minute or second hands. Following the adjustment of the one gear by the winding stem or the like the magnetic means effects coincidence of the two gears to accurately position the hour hand in accordance with the minute and the second. The two gears preferably replace the usual hour gear in a movement of this type but they can replace the minute gear. I
BRIEF DESCRIPTION OF THE DRAWING FIG. lis a cross-sectional view taken on line 1-1 of FIG. 2 through a timepiece movement in accordance with the present invention;
. FIG. 2 is a plan view partially in section taken on line 2-2 FIG. 1, and
FIG. 3 is a cross-sectional view similar to FIG. 1 but showing a modification.
I The watch movement partially illustrated in the drawing includes a time unit wheel such as an hour wheel la, which is, in mesh with the minute wheel pinion '2 of a power train including a minute wheel 3. The latter is rigidly connected with the minute wheel 3 which engages the cannon pinion 4. The cannon pinion 4 is frictionally mounted, in any conventional manner, on the center arbor 5. The hour wheel la is rotatably mounted on the cannon pinion 4 and center arbor 5. On the cannon 6 of the hour wheel 1a is freely mounted an additional wheel 1b, which is identical with the hour wheel 1 and carries the hour hand 7. The minute hand 8 is carried in the usual manner by the cannon 4' of the pinion 4 and center arbor 5, whereas the second hand 9 is carried, in a manner known per se, by a spindle 10 extending through a bore in the center arbor 5 and rigidly secured to another wheel (not shown).
The additional wheel lb is magnetically positioned with respect to the hour wheel la. To this end, 12 small permanent magnets l 1 are inserted into the hour wheel 10, these magnets being uniformly distributed about the axis of the wheel la. Twelve pieces 12 of soft iron,
I of the same size as the magnets 11, are secured in the additional wheel lb, opposite the magnets l 1.
to the usual winding and setting positions, a third position in which its actuation will drive means 13 to rotate vthe additional wheel 1b. Alternatively to this end a corrector of the type used in calendar watches may be used.
When the wheel 1b is rotated by one or more pitches, the hour hand 7 is also rotated, without influencing the indication given by the other hands 8 and 9. Thanks to the magnets 11 and to the pieces of soft iron 12, the wheel 1b always takes a correct angular position, the elements 1 1, l2 acting as a jumper-spring. The rotation of the wheel lb, under the action of the actuating mechanism by an operator, is not transmitted to the hour wheel 1a, since the magnetic force exerted by the magnets 1 1 is not sufficient for overcoming the friction of the cannon pinion 4 on its arbor 5. However, upon the normal running of the watch, the rotation of the wheel 'la is transmitted without difficulty to the additional wheel lb, since the latter is freely mounted on the cannon of the wheel la.
The magnets might also be mounted on the wheel lb and the pieces of soft iron on the wheel la. It would also be possible to mount magnets on both wheels.
Furthermore, one or both wheels may comprise a magnetizable material and be magnetized so as to obtain l2 poles or pole pairs.
In a modified embodiment, FIG. 3, the identical pair of gears may comprise minute gears 3a, 3b, the gear 3a being an additional minute wheel controlling the hour hand by means of house gear 1, said additional minute wheel being magnetically positioned with respect to the usual minute wheel. The magnets and the pieces of soft iron would then be fixed to the minute wheels and, due to the gear ratio between the hour wheel and the minute wheel pinion, the number of these magnets might be reduced tofour, for instance, if it is assumed that a quarter of a revolution of the minutewheel corresponds to a rotation of 30 of the hour hand. More generally, if the gear ratio between the hour wheel and the minute wheel pinion is denoted by n, the number of the permanent magnets and of the pieces of soft iron carried by the minute wheels, respectively, will be equal to l2/n.
The device as illustrated and described might also be applied to a timepiece (watch or clock) with a dial having a scale of 24 hours. In this case, one of the hour wheels might take 24 positions with respect to the other one, or one of the minute wheels might take 24/n positions with respect to the other one.
