Since the openings 20 are spaced 30 apart, movement of the index wheel Ill carrying the button 2| from one hole to the next adjacent hole corresponds to a one-hour setting of the hand 24.
It will be observed that the rotation of the index wheel ll relative to the hour wheel 5, to reset the hour hand does not stop or in any way interfere with the operation of the motor mechanism or movement 2; nor does it in any way affect the setting of the minute hand which is carried by a spindle or cannon 25 telescopically disposed within the cannon 6.
A dial disk index wheel 30 is mounted to rotate freely about the hub 8 of the index wheel l0, and the periphery of the wheel 30 is formed with ratchet teeth 3|. The wheel 30 carries a dial index 32, the outer marginal portion of which is divided into twenty-four sectors having indicia designating the twenty-four international time zones. These zones are given numbers which correspond to the number of hours necessary to add or subtract in the particular zone in order to correct the Greenwich mean time, the zones to the east of Greenwich being denoted by negative numbers and those to the west of Greenwich being given positive numbers. The dial 3 is formed with a small window 34 (Fig. 2) through which one of the marked sectors of the dial index 32 may be seen. The wheel 30 is yieldingly held against rotation and normally locked in set position by engagement of the free end of a small leaf spring 35 with the teeth 3|, the spring 35 being mounted on the outer face of the movement, as shown in Fig. 2.
It will be noted that the ratchet wheel 30 and dial index 32 are independently movable relative to both the ratchet wheel or index l and hour wheel 5, and hence the dial index 32 when being set may be moved through an angle different from that of the index wheel l0. Since it is generally desired to reset the hour hand by intervals of one hour, the angular movement of the index wheel l0 is 30, whereas the corresponding movement of the dial index (with twenty-four intere the two detent members engage the ratchet teeth l4 and 3|, respectively, and rotate the wheel I!) through an angle of 30 and the index 30 through an angle of 15. When the lever 40 is retracted from active position to neutral position, the resilient members 46 and 41 of the active detent, due to their resiliency, slide back over the teeth l4 and 3| without moving the ratchet and index wheels since both are yieldingly held in set position by national time zones) is 15". Accordingly the dial formed in the upper face of the movement. De-
as indicated by the solid dot-and-dash lines of Fig. 3, the resilient members 46 and 41 of one of the button 2| and the spring 35, respectively, with sufficient force to overcome the tendency of the spring member of the detents to cause reverse movement.
Rocking movment of the index lever 40 is controlled through a, link 5|] pivotally secured adjacent to one end to the lever 40 and at its opposite end to a rocker arm 52 pivotally mounted at 53 within a recess or relief portion 54 at the inner periphery of the Watch case I. The opposite ends of the rocker arm 52 carry leaf springs 56, the free ends of which engage the inner periphery of the case so as normally to hold the rocker arm in a neutral or inactive position, as shown in Fig. 1. A pair of push buttons 60 and 6|, received in openings formed in the case and held in place by springs 62, provides the operating means for rocking the arm 52 in one direction or the other.
With the construction and arrangement of parts herein shown the push button 60 may be depressed to swing rocker arm 52 ina clockwise direction, which movement of the rocker arm is transmitted through link 50 to swing lever 40 in a counterclockwise direction, as indicated by the full lines of Fig. 3. The counterclockwise movement of lever 40 brings the spring member 46 and 41 of detent 44 into operation to rotate index wheel ll] through an angle of 30 in a clockwise direction, thereby setting the hour hand 24 ahead one hour, and simultaneously rotates dial index 30 through an angle of 15, thereby effecting the corresponding change in the setting of the dial 32. Likewise, depression of button 6| causes a reverse movement of the hour hand and dial index. Thus, by simply depressing one of the buttons, the hour hand of the watch may be reset ahead or behind exactly one hour without interfering with the movement 2 or affecting the setting of the minute hand, and as the dial index is simultaneously set to indicate the particular time zone for which the hour hand is set, a mere glance at the face of the watch shows the exact time with reference to Greenwich mean time. By successively depressing one or the other of the push buttons, the hour hand and index dial may 'be set to indicate the exact time in any desired international time zone.
. While I have shown and described one desirable embodiment of the invention, it is understood that this disclosure is for the purpose of illustration, and that various changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
