1 Claim. (01. 58-58) This invention relates to horologioal instrumeshed with the gear l4 and mounted upon a ments and it has particular relation to a novel suitable shaft, not shown, is a gear 18 having wrist watch provided with a series of dials driven twenty-four teeth. A gear 19 having seven teeth by a conventional watch mechanismfor indiis mounted upon this same shaft and is eneating not only the time of the day but also the meshed with a gear 2E having 56 teeth and 5 day of the week, the day of the month, the mounted upon a shaft 2! which carries at its month and the lunar conditions. upper end an hour indicating dial 22. Below this The primary object of this invention is the dial and mounted upon the shaft 21 is a gear provision of an astronomical watch wherein nov- 23 having four teeth and below the gear 23 and el means is provided for driving a plurality of also mounted upon the shaft 2| is a gear 24 10 indicia bearing dials from a single conventional having a single tooth. Another gear 25 having a watch mechanism. single tooth is mounted upon the shaft 2! below Another object of the invention is the provithe gear 24. sion of a device of the character described where- A gear 26 having sixteen teeth is carried upon 5 in the dials are positively driven and the entire a suitable shaft 21 and meshes with the gear 23 mechanism is capable of enclosure within a case and also with a gear 28 having twenty-eight teeth. no larger than the ordinary wrist watch. To the upper side of the gear 28 is fastened a day A further object of the invention is the proviof the week indicating dial 3B. The gear 28 has sion in a Wrist watch of a novel arrangement of sleeve 3! revolubly mounted upon the Shaft go adja dials in pping relation for coni 3. This shaft i3 also carries a gear 32 having selvatien Of Space and a novel arrangement of twenty-eight teeth and having a sleeve extendindicia on the dials whereby the indicia on ading t h t Sleeve 31 and having th l r laeent a even though the dials ap, y condition indicating dial connected thereto.

The gear 34 is drawings, forming a p Of this disclosure, enmeshed with a gear 35 having twenty-four wherein; teeth carried on a suitably mount/ed shaft 33, the Figure 1 is a p View Of a Wrist Watch upper end of which carries a month indicating bodying the novel features of my invention; dial 31. Upon the gear 33 is mounted an annular 30 Figure 2 is a similar view with the face of the ring 33 bearing i di i for indicating the day of watch removed to disclose the construction of the month t i t th nds of the shaft de y parts; 13 is fastened a minute indicating disc 4!} which Figure 3 is Vertical Sectional View taken rotates therewith. As shown, all of the numerals s ntiallv 011 line of Figure 1; and 1 to 60 are not placed upon the dial in order that 35 Figure 4 is a plan View Similar to Figure 2 those which are shown may be more readily diswith the dials removed. tinguishable.
The embodiment of the invention disclosed in At t side of th casing r mote from the stem the accompanying drawings, broadly considered, 5 is manual adjustmg t 4! of conventional Comprises a Casing the lower part of which design for resetting the month dial 3'! and the 4,0 is designed to receive a conventional Watch dial 38. Coupling means 42 are provided at either mechanism I from which a plurality indicia end of the casing H] for attaching the usual strap bearing discs or dials are positively driven by utilized with Wrist watches means of Suitable i th m A face 43 is carried by the casing and is prog g fi g :g%:f g g ggi i vided with openings 44 for viewing the indicia 40 carried on the several dials. 2253 5 5g igdg g 251 522 :5 55; In operation, the watch mechanism 1 i is woun d fixed thereto gear l4 having eight teeth. Mountthe usual manner by tummg the stem and 1t ed upon a suitable shaft, not shown, is a gear 15 W111 Seen that h shaift by reason of the 0 having fourteen t t A conventional stem 5 gearing above described wlll operate to move the is provided for winding the watch mechanism ll hell! indicating dial 22 through One eemplete and carries a gear I! which may be en esh d revolution every twenty-four hours, the minute with the gear l5 for setting the hour dial and the indicating dial 46 once every hour, the day inrelated dials, hereinafter to be described. Endicating dial 30 once every week, the lunar con- 55 dition indicating dial 29 once every twenty-eight days and it will be seen that the day of the month indicating dial 38 will complete a revolution every thirty-one days unless otherwise adjusted by means of the stem 4| through the gears and 33 and that the month indicating dial, for all practical purposes, will complete a revolution once every year though it may be adjusted from time to time as is the day of the month indicating dial. It will also be, seen that whenever the particular month has less than thirty-one days, the dial 38 and the dial 37 may be manually adjusted by means of the manual adjusting stem ii. This stem 4! has a gear 45 which engages gear 83 for resetting dial 38.
The lunar indicating dial 227 bears a representation of the moon 53 upon its upper surface and adjacent the periphery of the dial, which representation is so placed as to show literally the various stages of the moon by means of an irregularly shaped opening 5i cut in the face of the clock.
Although but one form of the invention has been illustrated, and that form has been described in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various modifications may be made therein without departing from the spirit of the invention or the scope of the appended claim.
' I claim: v
An astronomical watch comprising a housing having sight openings in its face, one of the openings being of a predetermined irregular shape, a plurality of dials rotatably mounted within the housing for coaction one with each of the openings, said dials consisting of minute indicating dial, an hour indicating dial, a day-of-the- Week indicating dial, a day-of-the-month indicating dial, a month indicating dial and a lunar condition indicating dial bearing a representation of the moon and adapted to coact with the irregular shaped opening in the face to indicate the instant 'lunar condition, a conventional watch mechanism disposed within the housing, a train of gears interconnecting the dials and the watch mechanism whereby the various dials are'operated at predetermined speeds, one of the gears having afiixed to it the day of the month indicating dial, a stem protruding at one side of the easing for winding the watch mechanism and a second stem protruding through the opposite side of the casing and carrying a gear within the casing for engaging at will the gear carrying the day-of-the-month-indicating dial whereby it may be reset.
