atepresen'ting periods of time, such as the sea 55 Leonel-the months, anddayafl; This-base may constitute the top of a, table having legs. or supportsl,.of chann el=i-ron or the equivalent thereof, removably attached at .-their. upper ends .to eleatsf l", also ofchannel-iron, and having terminalangularly-disposed portions 1; forming seats for-the receptionof the upper ends of thel-legs=or standards. In theconstruction illustrated said legs are secured -i the seatsby means'of bolts 1.

. f spending from the base at an interme-; diate point is a spindle .3,'upon which is fmo'mitedesleeneAs-on the adjaeenteend of-a supporting-arm 5, and this supporting-armis provided at its free endwith a vertical spindle,6,"which extends upward through a segmental'slot 7, formed in the base concentric with the spindle 3 anddesigned to allow a a limited oscillatory movement of the support-- ing-armr Fixed to the spindle 6 at its upper extremity is a sun-globe-supporting plate 8, provided with acollar 9.,having a set-screw 10 by which the plate may be locked in place tofollowthe movements of the spindle 6.; In; a bearing 11, formed near. the outer end of saidplate 8, is mounted thesun-globe spin- I dle 12,- having acollar13, held in place by a set-screw 14 and adapted to bear 1 0 1 the upper-end of the bearing 11 to prevent dowry ward axial displacement ofthe spindle. The sun-globe 15 is provided with a collar 16, fitted npon thegupper ends of the sun-globe spindle and provided with aset-screw 17, by .whichit may be secured inplace, To the lower end of the sun-globe spindlei's aflixed a pulley 18; connectedby a belt-19 or other endless connection with a pulley 20, arranged concentric with the spindle 6. 'lo'conceal' the pulleys and bolt, the snn globe-support- 7 ing plate 8' is provided near its periphery 5 with a depending guide-flange 21. I

-. Mounted upon thespindle 6 forindependent revoluble movement is the hub or sleeve 22 of a'n-orbital arm 23, saidsleeve or hub 22 ward through the slot. 7 in the base,-.where it carries a radial arm 24, secured in place by means or a set-screw 25. This radial arm,

.which is arranged in the vertical plane of the orbital arm, is provided with' a pin 26, en-

gagedwith a slide or traveler 27, mounted for reciprocatory movement in a parallelsided guide 28 29, of which the partsare disposed upoh opposite sides of the'slot -7 and 'are secured to the under side of thelbase.

The slide or traveler is adapted to move from A one of the members of the guide across the slot 7 and into the other member of the guide during the rotary movement of the orbital arm 23 around the spindle 6 as its axis, and

in Fig. 2 will cause the spindle 6 to move westward, and thereby cause the movement of an earth-globe, supported by said orbital arm, to travel in an elliptical path.

Fixed to the spindle'thand hence held in a stationary position with relation to the supporting-arm, is a gear 30, a set-screw 31 being employed to facilitate the attachment of said gear, and mounted, preferably, in depending bearings 32 and 33 on 'the orbital arm is an operating-spindle 3l 'havinga pinion 35, which meshes with the gear 30 whereby as the orbital afin 23 swings aroun the carrying-spindle 6 rotary motion is communi cated to the operating-spindle 34. A'dnstguard 36, which is mounted upon the inner end of the orbital arm, serves the double function of protecting the. gearing and of supporting the pulley 20, and theprbital arm is preferably provided with a depending guardflange 37' for a-purpose analogous to that described in connection with the,snn-globe-sup-,

porting plate; Near its outer end the orbi-' tal arm is provided with an enlargement,

' forming a sleeve 38, in which is secured a tubular or hollow bearing 39, and within this tubular bearing is mounted an earth-globe: carrying spindle 40, provided at its lower end 7 with a gear -11, with which meshes apinion 4:2, carried by the operating-spindle 34. To

1 bearing 39 is a sleeve 48, forming a hollow or tubular spindle, to the lower end of which is fixed a gear 4-9, which also meshes with a 'pinion l2 from the opposite side of the gear 41, whereby during the movement of the operatiug-spindle the gears 4:1 and 49' are rotated in opposite directions or for a purpose herein-. after explained; Said sleeve 48 carries a pulley 50, which is connected by a belt, 51 with a pulley 52 on an earth-globe spindle 53,

ass i whereby rotary motion inaybe communicated from the operating-spindle-34 through the intermeshing gears 42 and 49' to the sleeve 48, and thence through the, belt-gearing to the earth-globe: spindle, while rotary. motion in the opposite direction is communicated from the same spindle 34 through the gears 42 and Y 41 to the spindle 40 to cause rotation-of the earth-globe-carrying. plate 44; in a direction opposite to that of the'earth-globe spindle. The means for demonstrating-the phenomaxis of the earth-globe 54, whereby said incliuation may be changed to illustrate the effect which would berproduced thereby upon thes'easons, are substantially identical with means for a similar purpose shown and described in my former patent above mentioned, and include a flexible earthglobe spindle having an upper section 53, c

at different inclinations around the main section of theearth-glohe spindle, and aspjndle 57, mounted toslide upon the upper earthglobe-spindle section and adapted to fit in earth-glohe-spindle section in anyone of a plurality of positions. In the construction illustrated, however, the parts are so related that when the upper earth-globespindle sec tion is in its normal position, whereby the axis of the earth-globe is ,inclined in the proper direction andcorrect angle toward the north, the center of the earth-globe is directly over the center of the earth globe'carrying spindle l0. In the construction illustrated in my former patent above named the-center of the earth-globe was located south of the earth-globe-carrying spindle for the purpose of illustrating theiarrangement of the'sunglobe in the northern focus of the earths ortration ofthe location of the sun-globe in the northern focus of the earths orbit is accom-' plished by disposing the sun-globe spindle in ens-dependent upon the inclination of the etther of said seatstomaintain said upper bit, but in the present construction the illusheated by a knuckle-joint with the lower or main section, said angularly movable section having the t too IIO

a position north of the axis of movement of the orbital arm is a collar 58, which is keyed to said sleeve to cause simultaneous rotation thereof or, in other. words, to allow independent axial slidthe collar. In the construction illustrated radial pins or screws 59 project from the collar mounted for axial sliding movement u pen the sleeve -i8 is a thimble .61, having a swivel connection with the collar 58, by means of pins or screws 62, fitting in an annular groove 63, formed in the outer side of the collar. collar carries the moon-globe-supporting arm 6 t, to the extremity of which :is aflixed the into longitudinal slots 60 in the sleeve. Also- The Mounted to slide-axially upon the sleeve 48 r ing movement of the collar while adapting the sleeve to communicate rotary motion to I one,

moon-globe 6.5;,and'it will be understoodfrom t e foregoing description that by communii eating reciprocate-r? motion to, the thimble 6,1" thecollar 58, with themoon-globe s'upportin gk arm, will' be correspondingly reciprocated;

while'rotary motiontothe collar'nmaybecoun municated from the sleeve 48','which=is-the ineans for commiinicating rotarygjmtion to the earth-globe spindle. :7. I

,The means which I havefLliistrated-in the drawings for communicating .rec'iprocatory operates in a slot 69, formed in a vertical guide 70, which rises from a dnst cap or guard "Z1, carriedby the orbital arm to :inclose the crank and adjacent gears; This combined reciprocatory and rotary movement of the. moon-globe-cariying collar 58' produces the orbitalmovement of the moon-globe; around the earth globeand at the same time the in- 'clination ofth'e plane of the moon-globe orbit to tj1at ofihe ecliptic; such inclination being about-five degrees. In addition, however, to.

" globe axis.

the above-described-movements of the moonglo'be it has an axially-tilting movement con sisting in an inclination of thenpper end of its'axis-toward thejearth-globe at one portion of the jmoons orbitand an opposite move ment, or away from; the earth, at another portion of its orbit. Toaccomplish this tilting movement, I employ a rocker 72, consisting of :a rim or band which encircles theupper. portion of the collar 58 and is provided with fulcrum-pins consisting of the guide-screws 59', andsaidrocker being sufliciently loose upon .the collar'to allow a tilting movementdownward for illustrating an axial inclination of about one and one-half degrees of'the moon- This rocker is provided with a radialstem 73, upon which is fitted a socket 74. at't -he inner end of the moon-globe-supfporting 'arm'64.- Also thesI'eev'eefS is provided with a longitudfiilal cam.75, formed, in

the construction illustrated, bylongitudi nail y channelingthe sleeve and providing the channel with-an inclined or beveled floor, and carriedby the rocker in operative relation. with this cam is a finger 76. Thus during the downward movement of the moon-globe' car ryingcollar the finger 76 is forded outward by the cam 75 to causean upward-swinging movement of the moon-globe-snpporting arm, and hencethe tilting of thenpper end of the moon-globe axis toward the earth, whereas during the movement of the moon-globe-carrying collar in an upward position the reverse operation is produced to cause the tilting of the moon-globe axis in a direction away from'the earth. p

The suns axis is-inclined at-an angle of about eight degrees toward that partofthe .earths orbit which the earth occupies in Sep 'tember, and in order that the center of the sun-globe shall be directly abovea line drawn June-to the 21st of December, said line passing directly through the center of movement :of'theorbital arm when the parts are in the vgiio'sitiims indicatedjin Fig. 1 and-in full lines i'nfFig; V2,.the sunrglobe-supporting plate is guzestpgardfrern saidlineconnecting the June and; December pbintsjofthe earths orbit,

12 to dispose the center'ofthe sun-globe directly over the line connecting the June and December points of the earths orbit, and hence accurately locates the sun-globe in the northern focus of said orbit. r

ing illustrated in a former patent above menplished allot the necessary movements of thethree celestial bodiesrepresented. The sunm ovement-nponitsaxis, the latter motion be- .ing due to the operation of the pulley 20,

abontthe spindle (3 as 'a center. Furthermore, said swinging movement of the orbital arm causes the shifting of its axis in a direction transverse to the majoraxis of the ellipse said elliptical motion. Furthermore,the-rev: olution of the gears 41-. and 19- in opposite directions, the latter beingbackward while carrying plate'e l to swingthrough one complete backward rotationwhile the orbital tion, and hence the inclination of the art-hs' axis remains-constant or uniform, or, 1n other itself throughout the orbital movem'entof the earth-globe. ever, receives a forward rotation to produce thedi'urnal revolution of the earth-globe, its direction of rotation corresponding with that of the earth, 3 I In practice I prefer to construct the gear 49 and hence it follows. that when the orbital and the gear 4i, which occupies the earth- 'globe-carrying spindle, has completed. one backward rotationthe gear 49 has not quite completed one revolution andhence the moon-globe has not quite completed one f0rward revolution'around the earthglobe. Thus at every revolution of the orbital arm the moofirglobe will fall a little more behind movement of the earthsorbitand the moons entendedfrom; thespindle 6 in a directioh' of the spindle 12'sIufficient1y far toward'that From the above description it will be seen that I have dispensed with much of the geartioned and at the same time have accom- I globe receivesran orbital and-also arotary caused by the rotation of theorbital arm 23 or orbit described-by the earth to produce arm23 describes one complete forward rota-- The earth-globe spindle, how-.

arm has completed one forwardcrevolution .globe spindle 53 for the reason that while the former carries the earth-globe and by its linear movement determines the orbitalmovement of the earth-globe the latter constitutes the axial support-of the earth-globe and controls the axial movement and position thereof.

hen the orbital arm 33 is in the position shown in Fig. 1 and the position shown in full lines in Fig. 2, the orbital arm 23 and the snpporting-arm 5 are in alinement, or both -are in the same vertical plane; but when the orbital arm 23 swings forward toward the position shown by the dotted line in Fig. 2 .the supporting-arm 5 swings backward and westward toward its position shown in dotted line and near the end of slot 7 in Fig. 2. The arm 23 will be at right angles to arm 5 slightly before the ceuterof theearth-globe has passed througlr a quadrant of its orbit'or the falling back of arm 5 has caused arm 23 to move more slowly than it would have done had arm 5 re mained stationary. -While arm 23 is movingforward from its position at right angles to :23 and 5 are in the same vertical plane.

arm 5 the last-named arm is swinging slowly back to its first position, so that when the center of the earth-globehas reached the northern end of the major axis of the earths orbit the arm 5 has assumed its first position and arms Thus the movement of arm 5 has caused arm 23 to move more rapidly in the second interval than it would have done had arm 5 remained stationary. For the same reason arm '23 will move more rapidly through the third quadrant and more slowly through the fourth, or.

the earth-globe is caused to move more rapidly in that half of its orbit from September to March than it moves in the half from March to September. In practice it will be understood that various changes in the form, proportion, size, and minor details of construction within the scope of the appended claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
