This invention relates to a combined. terrestrial globe and direct reading clock mechanism for mdicating the time in various parts. &- the world.

An object of the invention is to provide. a; new and improved terrestrial globe clock .of the vabove character in. which the. time indicator iscombmed with the structure: so thatit can be readllyvisie ble and at the same: time retain an. unobstructed view of the globe.

Another object is to provide a globe'xclockqof the above character wherein the cloclrmechan-ism is disposed within the globe and the globe base in such manner that the globe may .be turnedlior examination of different .parts thereof. l without afiecting the operation of the clock mec and without impairing the visibility- .ofathe time indicating mechanism.

Another object-of the invention is to provide a globe clock witha base arranged tosul pott and display direct reading time indicating meahsitogether with readily accessible manual meansfor adjusting or setting the time indicating means as desired.

Other objects: and advantages will. heroine/liter appear andfor purposesof. illustration,,-butnotof limitation, arr-embodiment ofnthe invention, is shown on the accompanying drawing in which:

Figure; 1 is a verticalsectionalwviewof a ten.- restrial globe clock with. portions. illustrated .in side elevation;

Figure 2' is anenlarged section'taken-substantiallyonthe line. 2-2 otFigure 1;. and

Figure v3 is a fragmentary. verticatsectional view of an arrangement forman-ually operating the time indicating-mechanism.

The invention-is illustrated. as .comprisinga globe clock consisting of a glassor-translucent sphere [0 made of. two parts .fittedtogetherdn overlapping relation. On the outside of the globe may be painted or otherwise suitably. applied a map of the world, so that a lampon. the inside will illuminate the outside of the globe... The globe I0 is mounted on a hollow base III to which leadwires [3 having a connecti'ng. plug. IA .atthe outer end. On the base. [2 are provided switches f5 and' I6 which control a clock operating motor and the lamp respectively.

Interposed. between. the lower section .ofrthe globe and: the base I2 is. a.- cyli'ndrical-ucasing. l8

Thcinlatfioml 22 and. tube 21: are connected-so they tum together along with the globe thereby-1 obviating disa-rrangement ofxthe wiring. The tube is provided with a polygonal flange 23 which abuts againstathe underside oi upper. .wall. of. the base; and. depending therefrom; is an enlarged extension .24 carrying three vertically spaced. con.- tact .rings fi withlwhich contact elements 2.8

I3 may beturned. as a unit. upon the baselZ.

Mounted. for relative rotation on theplatform member. 22. is; a. ring to are secured a plurality of upwardly, and, outwardly extending rods .or arms 42. The upper extremities of. arms project through. openings means .431 integral with the inner surface oi. an annulusv or ring 414 ofv glass or other suitable translucent .or trans.- parent material... The ring 44 is vertically. disposed withlthe walls thereof. substantially parallet to the axisotthe globe. Hi and is arranged midwaybetweenlthe opposite endsthereof. The outer, surface of the ring. (4 is formed with call.- brations; numbers and. other i-ndicia. fordesignating the time. Thus, when the. lamp 321s lighted. the indicia onthe. ring, MT willlherisihl'e from-the. outside oithe globe,..the,arrangement being such that the corresponding time in different parts of the world willbe-indicated; The map-is ordinarily divided by lines of longitude into the-different time zones to enable. the. timein different places. to be readily observed.

Theinside of the ring 4| formed with an annulanseries otgear teeth 53 with whieha .45 meshes; Pinion .45 is. mounted. on a verticalshait 54 having a. hearing within a. boss 55. integral with a. plate. 56' which ,is. removably secured. to and. spaced'from. the platform member 7.2 and serving. to locate the ring 4] ontthe plat- "form. shown, boltswithinthering 4]. secure the plate 56' to the;platform 22 in spaced relation. A suitable clutch ,5?! is interposed between parts of the shaft 54 to enable, the W30 he turned or I adjusted. independently. of the upper portion or the. shaft 54. Mounted. on the. upper .end' of the shaft 541s a worm wheel which. a worm. 441 meshes. The worm 48' isfilxecltto a horizontally disposed: shaft 60- iorming an extension otstheranmature. of theemotor. The motor 3'0 and associated parts is preferably of sixty cycle synchronous type as ordinarily used for electric clocks and therefore it is believed that further description thereof is unnecessary. The motor is shown suitably mounted on the platform 22 as by a depending supporting post.

The intermediate cylindrical casing l8 contains auxiliary or direct reading time indicating means of any suitable character. has been illustrated as including a shell or body 62 of sleeve form interposed between a top or cover portion 63 and a base 64 which is provided with the projection i9. These elements are secured together by means such as bolts 65. A plurality of windows or openings 66, preferably three spaced equally, are provided around the circumference of the body 62 and through which indicia 6! are visible. The indicia are suitably applied to the outer surface of rings 10 and II mounted for continuous rotation within the casing IS. The rings 10 and II are formed with annularseries of gear teeth 69 and i2 respectively. The teeth 69 mesh with a pinion 68 mounted near the lower end of the shaft 54, while teeth 12 mesh with a gear 12 of asuitable gear train to rotate the ring H ten times faster than the ring 10. Thus it will be apparent that the indicia on rings 10 and II are utilized to indicate the time in minutes by direct reading.

It will be readily understood that if so desired, a step by step or delayed action movement may be imparted to direct reading indicia by any suitable operating mechanism of that character, to replace the mechanism described. It will also be understood that by adding a third ring it would be possible to indicate the hour as well as the minutes should this be desirable. As the hour indicia on the ring 44 may be made of suflicient size to be readily visible, the additional ring in the casing I8 is not essential.

From the above description it will be clear that the electric motor imparts turning movement to the ring 4|, the arms 42 turning the time indicating ring 44 in the globe ill and rings 10 and H in the casing I 8 relative to the globe In. When it is desired to inspect diiierent parts of the globe, the same may be turned, turning the time indicating devices and associated parts with it. 'In order to make an adjustment in the relative position of' the time indicating rings, shaft 54 is provided with an enlarged knurled portion 75, located outside of the globe and casing I8, by which the time indicating rings may be turned as desired in view of the clutch 51.

It is frequently desirable to use a manually operable globe clock, for example, for demonstration purposes. In such event the arrangement fragmentarily illustrated in Figure 3, may be utilized. A shaft 54 is provided with a pinion meshing with the teeth of ring gear 4|. The upper end of the shaft has a bearing in the box 55' while the lower end of the shaft has an enlarged knurled portion 75. By such an arrangement, ring gear 4| may be rotated byhand to indicate the correct time at a certain place, on the glass time indicating ring within the globe. Subsequent rotation of the globe, and with the lamp lighted, will indicate the corresponding time in other parts of the world.

It will thus be apparent that I have provided an arrangement which enables the globe to be used in the usual manner, and in addition pro- Vides a direct reading clock, the parts of which do not in any way interfere with the surface of the map. In addition the arrangementis such I I Such means Ition, especially as defined in the appended claims.
