WATCH-DIAL.

EPEOIFZCATION forming part of Letters Patent No. 340,044, dated April 13, 1886,

(No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE I'IUNTER, of Elgin, in the county of Kane, and in the State of Illinois, have invented certain new and useful Improvements in \Vatch A Dials; and I do hereby declare that the following is afnll, clear, and exact description thereof, reference being had to the accompanying drawing, in wnich is shown my improved dial separate from a watch.

h'Iy improvement relates to the new method of noting the time by one series of consecutively numbered hours; and it consists in a watch-dial having the circle of twenty-four consecutive hournumbers, with the number 12 at the top and the number 2t at the bottom of the dial, and provided with a representation of hall the globe or earth entirely within the circle of numbers, and having its upper portion light and its lower portion clouded,

substantially as and for the purpose heroinafter shown.

In the annexed drawing, A represents a watch-dial, which, near its periphery, is provided with a circle, a, that is divided into three hundred divisions, each representing one-filth of a second of time. \Vithin said circle a is a second circle, a, which is divided into sixty spaces to indicate minutes, and

within the latter a third circle, (1?. that is divided into twenty-four spaces to indicate hours of time. In the outer circle, a, each fifth division-mark which corresponds in radial position to the minute-marks of the circle a is made longer than theintermediate marks, to enable seconds to be easily indicated. The

second circle, a, has each fifth division-mark designated by the proper number, commencing at the upper center, while the inner circle, a, has each division mark designated by a number, which numbers are arranged in consecutive order, with the number 12 at the top and the number 24' at the bottom of the circle.

Vithin the space inelosed by the inner circle,

a is a representation of a globe, a upon 5 which is preferably represented the continents of North and South America. The upper portion of said globe is represented as illuminated, whileits lower portion is in darkness, the former representing daylight and the lat 5o ter night.

The dial thus arranged is adapted to indicate the new system time with but little c0nfusion to its user, as the daylight hours are readily distinguished from the night hours by their arrangement upon the upper half of the dial and by their proximity to the light portion of the globe.

By arranging the number representing midday at the upper center of the dial, the num- 6o bers representing the daylight hours are in position to be most readily seen, and as there by the numbers representing the hours from daylight to midday occupy nearly the positions occupied by said numbers upon the old style dial, their use is as easy upon the former as upon the latter.

Having thus fully set forth the nature and merits of my lllVBllilO1l,WllZti3I claim as new is A watclrdial having the circle of twentyfour consecutivehour-numbers, with the number 12 at the top and the number 2; at the bottom of the dial, and provided with a representation of half the globe or earth entirely within the circle of numbers, and having its upper portion light and its lower portion clouded, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of De- 8o cember, 188?.

GEORGE HUNTER.
