CLOCK DIAL Filed May 3, 1932 ZONE 9 JAHm ZONE +4- 20m; -0 .1 MANIL I mums sTANDARD v mus-7 ONE *6 CENTRAL UNITED STATES CLOCK DIAL Andrew Eklund, New York, N. Y, Application May 3,. 1932, Sefiai, No. $29,651
4 Claims. This invention relates to a clock dial and has for an object to provide an improved clock dial which will serve not only for the purpose of tellng local time, but also for the purpose of telling i the time at selective zones and cities throughout Still a further object of this invention is to' provide means on this movable dial, which means as will not only serve to indicate the prevailing time in foreign or distant time zones, but which indie ting means will always remain in an easily cable position, irrespective of the rotation of dial Still a further object of this invention is to provide indicating means placed about the periphery of the revolving dial, which indicating means will always remain 'in' an upright or level reading position, enabling the same to be easily go read, irrespective of the rotation of the supporting dial.
With the foregoing and other objects in view,
as will hereinafter become apparent, this invention comprises the constructions, combinations and arrangements of parts, hereinafter set forth, disclosed drawing. In this drawing,
Figure l is a partly sectional view of the cloclc dial and operating mechanism,
Figure 2 is a plan view of the clock dial,
Figure 3 is a plan view of the blank for one of the zone plates,
Figure 4 is a plan view of the assembled zone plate, and v Figure 5 is a sectional view of the assembled zone plate.
There is shown at A a stationary dial ring around the surface of which are placed the numerals and divisions representing the hours so of the day in the usual manner.
The dial ring A is held stationary in an outer flange of a back plate B, which in turn is fastened to the frame C of the clock movement, not shown. An hour shaft E'operated by the clock mechanism, is provided for operating the hour and shown on the accompanyingv the time zone plates (Cl. 5H3) hand F about the dial ring A, and a shaft E within the hour shaft E serves to operate the minute hand F over the dial ring A in the usual manner.
A dial D is fastened on the outside of the hour shaft E, as clearly shown in Figure 1, whereby the dial D partakes of the movement of the shaft E and hence of the hour hand F. The dial D will be of such diameter compared to the dial ring A, that the outer edge of slightly under the inner as shown in Figure 1. Spaced about the plurality of time zone plates G are provided, one
edge of the dial ring A,
Each time zone plate G will have appropriate to two of the time zones on the world's surface, the time zones being eachtwelve hours apart. Although only a single city or the dial D will project 05 country has been shown on several of the time or more cities or countries may be shown for each zone on each dial plate G, this being merely a matter of appropriate selection. so
The hour hand F and the minute hand F extend across each of the time zone plates G successively during operation of the clock. In order to permit the successive time zone plates G F points thereto, the hour hand F and the minute hand F are each provided with orifices f and f, the orifice f on the hour hand F f on the minute hand F each being of a diameter at least large enough to permit the inscription on G to be readable therethrough.
Each dial plate G, as shown in Figures ii, i and 5, is made up of a blank of material folded over as at I, a supporting pin H having first been passed through the lower portion of the blank from which the plate G is formed. Except for and the orifice an the hinge portion 1, the dial plate G is substantially circular, but the depressed boss through which the supporting to the dial plate G so that plate G will hang suspended therefrom in the same positionfirrespective of the revolution of the supporting pin H. The supporting pin H is mounted in the dial D at the appropriate position, so that the dial plate G will hang level as the dial D rotates with the hour hand F, and the indieia on thedial plate 1] pin H projects is eccentric v 'scription. While the i will remain in a G will always remain in the level and readable position.
A plurality of arrows J are provided on the dial D at each plate G, to cooperate with the time marking on the dial ring A.
The novel features and the operation of this device will be apparent from the foregoing dedevice has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed and that changes may be madetherein within the scope of what is claimed without departing from the spirit of the invention.
Having thus set forth and disclosed the nature of this invention, what is claimed is:
1. A clock comprising a pair of time hands and a clock dial comprising a dial ring having the hours indicated thereon, a dial rotatable within the dial ring, a plurality of time zone plates mounted on the dial and cooperating with the dial ring, and means for mounting the time zone plates on the dial, whereby said time zone plates will remain in a level readable position throughout the rotating of said dial, one of said hands extending across each of said time zone plates successively and an orifice in said hands larger than the time zone plate diameter permitting each time zone plate to be successively visible therethrough.
2. A clock dial comprising a dial ring having the hours indicated thereon, a dial rotatable within the dial ring, a plurality of time zone plates mounted on the dial and cooperating with the dialring, means for mounting the time zone plates on the dial, whereby said time zone plates level readable position throughout the rotating of said dial, said means comprising an eccentrically placed depressed boss in each of said zone plates, and a pivot pin mounted in said dial, said depressed boss being freely mounted on said pivot pin, a pair of time hands mounted for operation over said clock dial, each time hand extending across said plurality of time zone plates, and an enlarged orifice in each time hand allowing a time zone plate to be readable therethrough.
3. In a clock having an hour hand shaft and a minute hand shaft, a dial ring on the clock having the hours indicated thereon, a dial mounted on the hour shaft to rotate therewith, the periphery of said dial slightly underlapping, the inner periphery of said dial ring, a time arrow on said dial cooperating with an hour numeral on said dialring, a time zone plate for said time arrow pivotally mounted on said dial, a minute hand on said minute hand shaft extending to said dial ring across the faces of said hour shaft dial and said time zone plate and an orifice in said minute hand of greater diameter than the time zone plate permitting said time zone plate to be readable therethrough.
4. In a clock having an hour hand shaft and a minute hand shaft, a dial ring on the clock having the hours indicated thereon, a dial mounted on the hour shaft to rotate therewith, the periphery of said dial slightly underlapping the inner periphery of said dial ring, a time indicator on said dial cooperating with an hour numeral on said dial ring, and a time zone plate
