Definitions
- This invention relates to a watch in which the time is indicated by revolving dials and the hour and minute hands are dispensed with.
- I provide a dial divided up into minutes and revolving once each hour, and a dial with figures or numbers from 1 to 12 is moved periodically beneath a plate in which there is an opening, so that the hour figure is exposed, and the minutes are denoted by the numbers on the edge of the revolving dial.
- Figure 1 represents the mechanism employed in connection with the hour and minute dials, the dials themselves being removed; and Fig. 2 represents the dials in their proper position and a portion of the mechanism behind the dials.
- the wheel 6, Fig. 1 is to be revolved once every hour by any suitable time mechanism.
- the arbor 1 of this wheel carries upon it a dial it, around which are divisions indicating the minutes, and adjacent to the edge of this dial it is a plate.
- L having upon it a pointer or index-mark 2 adjacent to the edge of the dial 7c.
- the wheel 6 gears into a similar wheel F, (shown by dotted lines in Fig.
- the star-wheelJ is upon an arbor supported at one end by the plate L, and such arbor carries a dial Q, upon which are the twelve numbers indicating the hours of the day, and the star-wheel J has twelve teeth, and this star-wheel J is held by the detent-N, having a double-inclined face, and a spring 'n to press the double incline of the detent against the teeth of the star-wheel J, and there is an opening in the plate L, through which one figure upon the dial Q can be seen.
- Adjacent to the snail-cam G is a lever H, having a double-inclined edge that is pressed against this 'suail cam *G by the spring h, and the respective parts are moved in the direction of the arrow, Fig.
- Covering-plates may be introduced at each side of the plate L and adjacent to the dial it, to hide the mechanism of the watch, if desired.
- I claim as my invention The combination, with the wheel 6 and arbor 1, revolved once in each hour by suitable time mechanism, of the dial 70, connected with the arbor 1,the arbor 3, and wheel F, gearing with the wheel 6, the cam G on the arbor 3 and connected to the wheel F by a pin in a slot, the star-wheel J, and hour-dial Q, the projection g on the cam G, for moving the star-Wheel, and the lever h, acting upon the cam G to move the same when the projection g is in contact with the star-wheel, substantially as set forth.
