WORLD-TIME INDICATOR TIMEPIECE This invention relates to a world-time timepiece, which comprises a minute hand and two hour hands, one of which is a l2-hour hour hand whereas the other is a 24-hour hour hand or a 24-hour graduated disc.
It is an object of the invention to provide a wrist watch which indicates to a person who is traveling between two places having different times (zone times) both the time at the place of departure and the time at the place of destination. A timepiece according to the invention may be used for the same purpose also as a wall-clock or the like in vehicles for longdistance transportation, such as aircraft, ships, railway trains and buses.
The above-mentioned object is accomplished in the timepiece according to the invention in that the two hour hands can be set arbitrarily either jointly or separately. The l2-hour hour hand may be set independently by a disc, which is concentric with the axis of the hand and on which time zones are indicated, e.g., by the names of representative places. The zone disc may be rotated in steps in both directions by a setting shaft, which protrudes from the watch housing and is provided with a setting knob, or two pushbuttons may be mounted in the watch housing and may be operable to rotate the zone disc in mutually opposite directions by means of a lever system. Each step has an angular extent of 15 15 X 24 hours 360). The dial may have a window, which exposes one sector of the zone disc. Alternatively, the zone disc may consist of a finger-engageable ring surrounding the dial. The 24-hour hour hand may consist of a graduated disc, which is rotatably mounted and disposed under the dial, and a sector of this graduated disc may be exposed in a window of the dial.
Before a person begins a trip, he sets the zone disc to the place of destination so that the 12-hour hour hand indicates the time at the place of destination whereas the 24-hour hour hand continues to indicate the time at the place of departure. Hence, the user can check his watch at any time to find out whether the time is proper for a telephone call to his home town or whether such call should be deferred because the time is not appropriate. Besides, the timepiece according to the invention may be readily shifted to indicate the time of any place of the world when such time is desired as a basic time for any purpose whatever.
The l2-hour hour hand and the 24-hour hour hand are set jointly in the previously usual manner.
Further details of the invention, particularly of the watch movement, are diagrammatically illustrated, partly in section, in the drawing which shows illustrative embodiments of the invention.
FIG. I is an axial sectional view showing a watch movement embodying the invention.
FIG. 2 is a top plan view showing the dial of a watch in one embodiment of the invention.
FIG. 3 is a top plan view which is similar to FIG. 2 and illustrates another embodiment of the invention.
FIG. 4 shows one embodiment of the means for setting the zone disc.
F i6. 5 is an axial sectional view showing a watch movement which embodies the invention and comprises a zone disc which is set by a rotation of an external finger-engageable ring.
FIG. 6 is a top plan view showing the embodiment of FIG. 5.
FIGS. 1 and 2 of the drawing, illustrating one embodiment of the invention, show a center wheel arbor l and a cannon pipe 2, which are frictionally connected in the usual manner. The cannon pipe 2 carries a minute hand 12. Torque is transmitted from the cannon pipe by the minute wheel 3 to the minute pinion 4.
As far as to the minute pinion 4, the transmission of torque is the same as in usual wrist watch movements. In the watch movement according to the invention, torque is further transmitted to a 24-hour wheel 5, which is geared to perform one revolution in 24 hours. Hour wheel 5 is connected to hand 11, the outer end of which is spaced from, but associated with, a
24-hour scale 26. A flat cup 6 having an internal series of teeth 7 is keyed to the hour wheel 5 so that parts 5, 6 and 7 form a unit, which rotates through 360 in 24 hours.
Arbors for the planet pinions 8 and 8a are mounted in a zone disc 15 and are stationary during normal operation, planet pinions 8 and 8a are disposed to coact with the teeth 7 and with teeth (not shown) on the outer periphery of l2-hour wheel 9, and because there are twice as many teeth 7 as there are teeth on the l2-hour wheel 9, the latter will rotate through 720 during one revolution of the 24-hour wheel 5, cup 6 and teeth 7 so that the transmission ratio is 1.2.
By means of an axially displaceable setting shaft 17, the zone disc 15 may be engaged with the setting wheel 16 and may be rotated thereby. The planet pinions 8 and mounted in the zone disc 15 follow the rotation of the latter to transmit the angular movement of the zone disc 15 to the l2-hour wheel 9. As has been stated, these are twice as many teeth 7 as there are teeth on the l2-hour wheel 9 so that the angular movement imparted to the l2-hour wheel 9 by the planet pinions 8 and 8a, in the opposite direction, is twice as large as that imparted to the zone disc 15.
As a result, an angular movement of the zone disc through 15 corresponds to an angular movement of 30 of the l2-hour wheel 9, which corresponds to 1 hour of the associated 12- hour scale 25. Owing to the frictional coupling between the center wheel arbor l and the minute hand tube 2, the unit consisting of the 24-hour wheel 5, the cup 6 and the series of teeth 7 remains unchanged and connected to the watch movement.
As in all conventional watch movements, the hands I2, II, and 10 may be jointly set at the same time by means of the winding shaft not shown. The sweep second hand 14 is a friction fit on the second wheel shaft 13, in a conventional manner. A calender date ring 24 is rotatably mounted under the zone disc 15 and the dial 23 and is visible through a window.
The zone-indicating towns printed on the zone disc 15 are visible through a window in the dial 23.
The watch movement frame 21 and 22 is surrounded by a ring 20, in which the setting, mechanism, including elements l6, I7, 18, to be described later, detent device I9 in the form of a split-pin are mounted. The ring 20 is mounted in the housing 29, which is provided with a minute-second scale 27 and with a glass cover 30.
As is apparent from FIG. 3, the 24-hour hour hand may be replaced by a friction-fitted hour disc having a 24-hour scale and performing one revolution in 24 hours.
As is apparent from FIG. 4, the setting mechanism l6, I7. 18, and 19 shown in FIGS. 1 and 2 may be replaced by pushbuttons.
FIGS. 5 and 6 of the drawing show another embodiment of the invention. As seen in FIG. 6 the timepiece is similar in some respects to that described in conjunction with the embodiment of FIGS. 1 and 2. Thus, the timepiece has a dial face 23 over which the l2-hour hand 10, the minute hand 12 and the sweep second hand 14 move in association over appropriate scales under the impetus of a clockworks, which can be conventional. In this connection reference numerals used, and described, in FIGS. 1 and 2 are applied to the same pieces in FIGS. 5 and 6 and therefore will not be described here again in detail.
The embodiment shown in FIGS. 5 and 6 differ from that of FIGS. I and 2 in two principal areas. First the reference 11 as used in FIGS. 5 and 6 designates a 24-hour scale which is in the form of a disc instead of a pointer as in FIGS. I and 2. This disc, with the 24 numerals on its outer periphery is rotatable, in a manner to be described below, under dial 23, and as best seen in FIG. 6, the numerals are visible through a window in dial 23 and can be read with reference to a pointer mark 31 on dial 23.
The second area of difference is that a rotatable adjusting ring A" is used to rotate the zone disc 15 instead of the setting shaft 17 and setting wheel 16. As seen in FIG. 5 this ring A" is rotatably supported by ball bearings 32 between housing 29 and ring 20. Pinion 33, secured to ring "A, transmit torque to the wheel 34 which carries a shaft member B. This shaft member 8" is rotatably mounted in ring 20 and has the pinion 35 at one end to transmit torque to the zone disc 15. A pointer mark 36 provides a setting mark for ring A so that time areas for various cities of the world, printed on the disc, can be set to indicate the 24-hour time for a particular city. Thus in H6. 6 the time for Paris, on the 24-hour scale 11, is shown as 2107.
Referring to FIG. 5 it can be seen that a leaf spring 28, disposed between dial 23 and zone disc 15, urges zone disc 15 against l2-hour wheel 9 which in turn is urged against fiat cup 6. As the 24-hour scale 1 1' is fixed to this cup rotation of zone disc 15 turns l2-hour hand 10 through l2-hour wheel 9, but as in the embodiment of F I68. 1 and 2, the unit consisting of the 24-hour wheel 5, cup 6, and the series of teeth 7 remain unchanged and connected to the watch movement.
The invention may be embodied in mechanical electric and electronic wrist and pocket watches and in all kinds of tableclocks, period-clocks, large-size clocks and wall-clocks.
