This table top is provided with a bearing 21, receiving a preferably tubular vertical shaft- 22 provided above the bearing with a ring 23. clamped to the shaft 22 by any suitable means. Arranged beneath the table top is a horizontal bevel gear 24;, rigidly attached to the vertical shaft'22for rotating the same, and this bevel gear is engaged and driven by bevel gear 25, rigidly mountedhpon a horizontal shaft 26, journaled in bearings 27. The? shaft 26' is equippedawith a crank 28, Figure 1, for turning the same. Means are thus shown to manually rotate the vertical shaft 22 but it is, of course, understod that this verticalshaft may be driven by power or by any suitable means.

The vertical shaft 22 is provided near its upper end with'openings 29, receiving the reduced end 30 of a horizontal radial shaft 81, having a shoulder 32. The reduced end 30 is screw-threaded for receiving a nut 33.

34, embodying the usual electricbulb and refiector for projecting light upon the earth as will be described. :The electric lamp-34 is mounted upon an upstanding rod"35,' the upper portion of which is laterally ofi'set, so thatthe source of light may be spaced a suitable distance from the earth and will not 'obstructla proper view of the earth. The

lower end ofthe upstanding rod 35 is provided with "a flattened portion 36, having a vertical slot'37,to receive the reduced end This flattened. portion 36is arranged between the nut 33 and a washer 38, and may be rigidly clamped'tothe shaft 3lbyscrewing up thenut 33. The source of light thus be properly projected upon the earth. Of

course, the source of light could be suspend ed from theceiling or'the like,- and an or.- dinary electric bulb might be employed with some degree of success. By embodying a source of light having a reflector projectingthe rays in one direction, and traveling 1 with the vertical shaft, the effect of the relatively stationary sunis obtainable.

Mounted upon the table top 20 is a stationary gear or rack 39, surrounding the vertical shaft 22. This gear has inwardly pro-' jecting lugs 39 whichare rigidly attached to the'table top 20 by bolts 40 or the like. The stationary gear 39eis slightly elliptical,

corresponding .to the shape of, the orbit of the earth, the vertical shaft 22 representing the location of the sun. The numeral 41 designates acarriage, which is disposed radially ofthe stationary orbit gear 39. This carriage may be of anyfwell known or preferred construction, and embodies a frame 42 mounted upon wheels or casters 43, traveling upon the table top. Any other suitable form of'rolling means may be employed.

'Rigidly attached to the upper and lower ends of the frame 42v are relatively heavy metal plates 44 and 45. r The numeral 46 designatesasocket slidably receiving the outer endof the radial shaft 31. This socket has V outwardly'diverging arms '47, preferably in tegral therewith, andthe ends of these arms are rigidly attached to the lower plate 45.

by the plate and extending above'andbelow this plate; The shaft 50 has a gear 51' rigidly. mounted thereon, see Figures 3 and 4,

and this gear permanently-engages the sta- ;.-tionary' orbit; gear 38. \The; permanent en'- gagement is-maintaine'd by the self-adjusting longitudinally extensible connection affordedby' th'eshaft 31 and-socket 46. At its upper end, the-shaft 5O hasa gear 52, rigidly mounted thereon, engaging a gear 53, which is arranged between -the'pl'ates 44 and'45.

Thegear53 is rigidlyrmounted upon' a vertical shaft 54, journaled in bearingsformed upon thelplates 44 and 45. This shaft is disposed-centrally of the carriage 41 and the carriage;-topi55,.and projects upwardly bef yond the-'c arriage-top;The ratiobetweenthe gears 51 fand i 39 (is. the same as between the gears 52 -and 53. Theratio loetween the gears 51 and 39 may be'39. and between the gears .52 and 1-43." The: gear 51' is turned upon its axis. of rotation. in one direction by virtue" of its. travel about'the orbit gear 39, and the gear,53,through the medium of the" intermediate gear 52,is rotated in an opposite direction to the gear 51', and as the ratio be} tween the gears in the two sets is the same,

ther embodies an upper plate which is rigidly connected with the lower plate by purpose to be explained.

as explained, the result is that a support carried by the vertical shaft 54 will have its longitudinal axis maintained in a fixed position with relation to due north and south. The top or platform 55 is, of course, rigidly mounted upon the carriage 41,.and has its periphery divided into twelve segments 56, having designations indicating the months of the year 'andthe days of each month. The

names of the months appear upon the top of the segments, while a scale 57 is formed upon' the edge of each segment embodying lines and numerals, as shown. Each vertical line in the scale represents the day of the month, and the lines are numbered in sequence,r increasing in onedirection. A point-er to be described, travels in close relation to the'scales 57. p

An operating gear 58 is mounted centrally uponthefplatform 55 and 'is'rigidly attached thereto by screws 59 or thelike, to move bodily with thecarriage about the orbit gear.

This operating gear is provided with a hub 60 to slidably receive the upper portionof a The upper end of this shaft projects upwardly beyond the hub 46 and is provided with a reduced extension 61, formed square in cross section, thereby havingpar- A frame 62 1S mounted upon the frame embodies a lower plate 63, having reinforcing stiffening ribs 64. The plate is pro- 'videdcentrally thereof with a depending socket 64', having a bore square in cross sectionto receive the square end61 of the shaft. The plate 63,.therefore, remains fixed with relation to the shaft 54, during its travel The frame 62 fur-e rods 66, preferably four in-number- -These rods have their ends screw-threaded for receiving nuts67, arranged above and below theplates, the rods passing through openings :inthe plates, as is obvious. By proper manipulation of the nuts 67'engaging the upper plate 65, this upper plate may be inclined with respect to the carriage, for a r The numeral 68 designates the earthor globe, which is. carried by an upstanding mace .and rotates with this. rod. The rodextends through the axis of rotation of the.

globe and is arranged atthe proper inclination for-illustratingthe inclination of the earth upon its axis. The globe-carrying rod 69 has its lower end rotatably mounted in openings'ZO, formedin theiends oftheinclined portions 71 of brackets 72.-Thes'e' brackets have vertical portion 7 3, whichextend through openings? 4 in the upper-plate 65 and hence have no connection withv this plate. The lower ends of the vertical'portions '1 3 extend through openings in the lowor plate 63 and carry nuts 75, arranged above and belowthe plate 63, for clamping engagement therewith. The brackets 72 are disposed in-theplane of the inclined, globe carrying rod 69, and, remain in this plane throughout their travel about the orbit gear.

Byvirtue of this arrangement, the fixed inf clination of the ea-rthsaxis, due north and south, is maintained as the globe travels about the orbit gear. A flexible shaft 76 isattached to the lower end of the globe car rying rod 69 to rotate the same, and this flexible shaft extends-through an opening 77 in the upper plate The flexible shaft is connected with suitable gearing in turndriven by the operating gear 58, in such a manner that the globe is rotated upon itsaxis, and

will make the proper number of revolutions 'for'its complete travel throughout its orbit,

simulating the rotation and travel of "the earth. I p I P A gear frame 7 8 is rigidlymounted upon one end of the lower plate 63, and embodies spaced superposed horizontal plates 79, connected byv'ertical' rodsv 80. :A' gear 81 is mounted upon a vertical shaft 82, attached to the lower and of the flexible shaft 76.

The shaft 82 is journaled in a bearing 83 and an opening formed in a bracket 84, attached to the upper plate 79. The gear 81 is held against longitudinal movement and engages a larger gear'85. Gears "81 and-85 preferably have a'ratio of 1"'2.= Thegear 85 is rigidly mounted upon, a vertical shaft 86, suitably journaledin bearings carried by the two upper plates 79; The vertical shaft 86 has a gear 87 rigidly secured to its lower end,-engaging a largergear ,88. The gears.

87 and 88 preferably have a ratio .of 1'3.

I The gear 88 is rigidly mounted upon a' vertical shaft 89, j'ournaled in suitable openings formed in'thetwo upper plates 79 and a smaller gear 90" is rigidly attached to the lower endofthe vertical shaft'89 and engages a larger gear91. Gears 9'0-and'91 preferably have :a ratio'oflf,6. Gear 91 is rigidly inountedupon avertical shaft 92,-journaled in bearings formed in the two lower plates 79, and a gear 931is rigidly mounted gupon 1 f the lower end of the vertical shaft 92; Gear 93 is iii-permanent engagement with the operating geary58, and these gears preferably {have a ratio 0f1'-'1 0 .v It is thus seen that as the frameis traveling with the carriage in its orbit aboutthe' orbit gear. 39, the. frame having its longitudinal axis maintained due "nortl'i and. south, "while the radial position of thewheeled carriage'is constantlyfchanging, there is a relative turning movement'between the operatinggear 58 and the gear 93, causing the train" of gears embodying this gear93 to turn and this turning movementfis transmitted to the rod 69, rotating the earth upon its axis. The gearing is ofsuch a character that the globe makes a complete revolution for each day.

';.; ,The lower. plate 63 is provided with a pointer 94, traveling in proximity to theedge of the platform 55 for co-action with the month scales 57. Thus as the pointer 'iindicates the movement of the earth in its orbit for one day; the globe 68 willbe turned for one complete revolution.

Means are provided for supporting a moon in proper spaced relation from the earth and moving the same bodily around the earth. This mea'nsin'cludes a generally inverted U shaped bracket 95, having vertical legsv 96, which are rigidly attached at their lower ends to the upper plate 65 0f the supporting frame, adjacent to the periphery of this zontal portion 95, as shown'at 101, to rotate horizontally with relation to the supporting bracket, the supporting rod 97 turning within the supporting bracket. At its free end, the arm 99 ispreferably provided with-1a hook 102 for receiving the eye formed upon the end of a dependinglink 103carrying'a "moon 104 rigidly attached thereto. Both the moon and earth may have their surfaces painted or otherwise formed for indicating thesurfaces of the earth and moon.- The' horizontal arm 99 supports the moon at a suitable distance from the earth '68 and "causes the moon 'totravel about the earth,

making a complete movement in its orbit,

each lunar month. The upper plate 65, see particularly Figures 1,3'and 5, is provided with an upstanding annular flange 105 and a depending annular flange 106, integral therewith. These flanges serve to stiffen and reinforce the upper'plate, and the upper flange 105 serves as a guide for the endless sprocket chain 100.] portion of the upper flange 105' is cut away, providing a'space 107, spanned by the sprocket'chain '100 and the sprocket chain at this space engagesa sprocket wheel 108. 'A lever 109"ispivote d to the upper plate 65', {at 110, and carries a roller 111, engaging with the sprocket chain 100. A retractile coil spring 112isconnected with the'lever and may be attached to one of the brackets 71 and serves to swing the rent engagement with the sprocket wheel 108. The sprocket wheel 108, see Figure 13 particularly,'is rigidly mounted upon a vertical shaft 113. and this shaft is journaled in openings formed infhorizontal' platesllet, included in a gear frame, rigidly attached to the lower plate 63 diametrically opposite the ,lever l09 inwardly, thereby maintaining" the sprocket chain suitably taut, and in permafirst named gear frame." The shaft 113, Figure 6; has a; small gear- 115,: rigidly attached thereto; and engaging a; larger gear 116, rigidly .Isecured" to. the vertical; 1 shaft 1 117. Thesegears preferably have a ratio-of 1*'-6.

, The" shaft 117 is journaled in openings formed in the plates '114: and this-shaft ex.- tends downwardly belowthelower plate 63 and has a gear118 rigidly attached thereto,

engagingthe operatinggear 58.- These gears preferably haveiaz ratio of -11%.

This position the; rays of light from the sun shining principally upon the upper portion of the earth,

producing practically six months of day .at the P19 6. 'fifidsi-r months? of night at of myinvention, or the the SouthPole, during the summer months and vice'v'er'sa{during'the winter months. The operator now turns the crank 28clockwise at a suitably slow speed and the vertical shaft 22 isrotated, causing the radial shaft 31 to'travel circumferentially-of the orbit gear 88. This movement of theshaft 31 effects the orbittravelof the carriage 11. During this orblt travel of the carr1age',such carriage is constantly changing its radial position, while the longitudinal axis of the supporting frame, including the plate'63, remainscon- 'stant, due north and. south. This is eiiected by'th'e rotation of the'gear; 51'byithe orbit gear 38., The gear 51 throughthemedium of gear52 rotates gear 53v in an opposite direction,- and theratio'betweengears 51 and 38 andgears 53 and 52 is the same-as eX-- plained.

Hence, gear 93 is driven. by the operating gear 58' and through the mediumof the train ofgears connected therewith, rotates the earth carrying rod 69, causing'the earth to make 365 complete revolutions upon its 'longitudinal am's during the time that'itcompletes its travel throughout its orbit. Theearth, therefore, makes a complete'revolution upon its aXis for each day. In a'similar manner, the gear 118 is rotated by the gear 58, and through the medium of the associated train of gears, and endless sprocket chain, 'the mooncompletes its travel through its orbit aboutl the earth in a lunar'month: As the pointer 94 reaches each month segment, the relative posi tionof the earth to the sun is efi'ected and the light projected upon the earth from the lamp '34, showing just how the-light strikes the earth in each month. Thea ction of the moon is alsoclearly indicated "by the apparatus,

"and the moon trayelis in its orbit about the earth; the various cha n es I'for' phases of the moon are clearly visible, due tothe action of the light projectedfupontheearth anclinoon.

Th eclipse of the sun is produced when the 7115 1 moon passes betweenfthe 'sourcefoflight the earth,and theeclipseot thefmoon is pro duced'when the earth passesbetween the sun and the moon. The apparatus is, therefore, capable of demonstrating in a simple and reliable manner the various'actions of the earth and moon, withrespect to'the sun.
