WITNESSES UNITED STATES PATENT Orrica WILLIAM H. NEWBY, OF COLUMBUS, INDIANA, ASSIGNOR OF ONE-HALF TO JEROME B. SHAW, OF BROOKLYN, NEW YORK.

WATCH-DIAL.

SPECIFICATION forming part of Letters Patent No. 290,791, dated December 25, 1883. Application filed January 25,1883. (No model.)

To ail whom it may concern.-

Be it known that 1, WILLIAM H. NEWBY, a citizen of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful \Vatch-Dial, of which the following is a specification, reference being had to the ac companying drawings.

This invention relates to watch, clock, and other time-piece dials, and has for its object to provide a simple form of dial by Which different time can be indicated by one set of hands for any desired purpose. Thus one watch can be adjusted to show the time at two I 5 different placesas, for instance, New York and San Francisco.

In the drawings, Figure 1 is a face View of a dial and hands or pointers embodying my improvements. Fig. 2 is alike view, showing the hands or pointers in a different position. Referring to the drawings, A designates a watch-dial, which is substantially of the usual construction, and having the ordinary time graduations on its face, these latter consisting of the numbers 13 and scale of minute-degrees O around the outer edge. An ordinary hour hand, D, and minute-hand, E, are also em ployed. At the central portion of the outside large dial, A, is arranged a smaller dial, F, having the hour-numerals Garranged around its outer edge. This inside dial is rotated or turned around the pivot of the hands, while the outside dial is fixed, as usual. The rotation of the central dial, F, can be effected by 5 any suitable'gearwheel mechanism connecting it with the main works of the time-piece, this mechanism being preferably like thatcommonly used to rotate the hubs of the hands. If desired, a separate clock-work mechanism 40 can be employed to rotate the central dial, and

under some circumstances the dial can be arranged so as to be only adjustable by hand when it becomes necessary to change the relative arrangement of the parts. On the min- 5 ate-hand E is adjustably secured in any suitable manner a smaller hand or pointer, H, arranged approximately crosswise or diagonal in relation to the said hand E. As the hands D and E travel around the outside fixed dial they indicate the time thereon in the usual manner. During this movement of the main hands the inside rotary dial turns so that the hour-hand D will indicate a different time on this inside dial from what it indicates on the outside dial, and the small pointer H on the minute-hand E will indicate the minutes on the inside dial. For example, on the dial shown in Fig. 2 of the drawings, the regular time is twenty-six minutes past nine, while the time indicated by the hands I) and H on the inside smaller dial is half-past eight.

Undersome circumstances the smaller inside dial may be fixed so that the extra time will be indicated by the hands D and H without revolution of the smaller dial.

Of course the inside dial and the hand H can be adjusted to regulate the extratime, so that, should a person be in San Francisco, he can have his watch adjusted or regulated to indicate the relative time at New York, Ohicz'igo,

New Orleans, or any other place.

I claim as my invention As an improvement in watches and clocks, the combination of the outer fixed dial, having the concentric circle of figures representing the twelve hours and having the minute-gr du ations, the inner dial, having a concentric circle of figures representing only the twelve hours,an hour-hand common to both dials, and indicating the hour on both dials at one time, an independent minute-hand moving in relation to the common hour-hand, but indicating the minutes only on the outer dial, and an auxiliary minute-hand carried by the main minute-hand and indicating the minutes only on the central dial in relation to the hour designated on the same dial by the common houn hand, all arranged and operating substantially as and for the purpose set forth.

In testimony thatI claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM H. NEXVBY.
