T0 all whom it may concern:

Be itlmown that I, WILLIAM E.V Gourm- NoUn, a citizen of the United States, and resident of Portage, in ,the county of Columbia and State of -TWisconsim have invented certain new and useful Improvements in Automatic Tellurians; and I do hereby declare that the following is a full, clear, and exact description thereo.- l

This invention relates to tellurians. Y.

One of the objects of thisinv'entionis to provide a tellurian which gives the correct motion of the several parts of the apparatus and illustrates the varying seasons, night and day, the different phases of the moon, and other similar phenomena.

`Further objects are to provide a. tellurian which is electrically driven in a continuous and convenient manner, to thereby allow the demonstrator to devote his entire attention to illustrating the various features which he desires-to emphasize; and to provide a tellurian which is electrically lighted in a manner to simulate the substantially parallel rays of the sun. Y Further objects are to provide a tellurian which is so organized that portionszthereof may be readily disconnected from the main drive so that the demonstrator may rapidly run through the seasons, for instance, or give other demonstrations without waitinguntil the parts have been automatically, moved to the desired position; to provide a tellurian which may be readily separated to facilitate packing and Vshipping without, however, in

automatic any 'way damaging the apparatus; and to provide fa .tellurian in which the electrical. connections are automatically established when the parts are again slipped into position. Y Y

An embodiment oi' the invention is shown in the accompanying drawings, in which Figure l is a side elevation of the device, with parts in sections to more clearly illus trate'the mechanism. Y

member or housing 1, with a removable bottom plate 2, held in position by means of the' threaded legs'or supports 3. Vfithin; this base an Velectric motor, 4, ismounted upon the base plate V2, as shown inthedrawings, and 1s provldedjwitha yworm 5,' upon its drive shaft. A jU--shapedy bracket 6-is secured to the base andnrnishes bearings for.

a transverse shaft 7 Vupon which are rigidly mounted a worm wheel and a bevel gear,`

9. The bevel gear 9 meshes witha second Y i bevel gear 10, whichis carried upon'a pro-vr jectie-nal Yshaft 11, journaled in the'upper portion oi' the bracket 6; this shaft is provided witha pinion 12,'which maybeconveniently locateduponfits upperV end and which meshes Vwith a largergear13.V The gear 13 is rigidly secured in any convenient therefore', afsupp'ortfor the sleeve land the gear 13.' lA pair of bevel gears,l19 and 20, of different diameters, arel rigidlyfattached to the stationary sleeve 16-7-the smaller of such gears,'20"being mounted above the larger gear, as illustrated in the drawings, for 'a iurpose hereinaiterftoy be described. 'v

A horizontal beam 21, is rigidly.'securedV to a sleeve 22,` in any convenient manner, as by .means of a nut 23threadedupon theupper endo-l' such sleeve.V and ,clamping the beam against a lower collar SeeVV Figure yThe sleeve 22 isinounted within the sleeve 15 `and lis loosely splined thereto,V as indicatedpat 25.'- The lower end of the sleeve 22,v carries an electrical contact 25, mounted in a suitable insulating disc which bears against a stationary contact 26, which maybe Vconveniently supported by an insulating member Y277, extending from 'the bracket 6.?"Arsuitablelead 28 is connected' to the stationary Contact 26, Vand afwire .29is" connectedto the/movable Contact` 25, and extends upwardly througli'thehollow. i portionrof'the sleeve 22'.Y This wire Ventends to an electrical lamp 30V-fthe Aother, terminaly of the lamp being connected tothe frame of the machine and communicating with a source of electrical energy by way of the lead 31-see Figure 3-connected to some suitable portion of the u apparatus. The lamp is conveniently carried by a standard 32, rigidly attached to the shorter arm of the beam 21. A reflector' 33, is carried by the standard 32, in any convenient manner and aids indirectly projecting the rays in an approximately parallel manner towards the other end of the apparatus.

The long arm of the beam 21 carries a revolubly mounted frame 34see Figure 1- through which extends a vertical shaft 35. This shaft is provided with a driving gear 36, which meshes'with a bevel gear 37, carried by a horizontal shaft 38'.V The upper end of the shaft 35, is rigidly attached to the frame 34.V This lower end, however, is detachably connected to the gear 36. The coupling or joint between the gear 36 and the shaft 35, may be of any desired type, as for examplathe slotted collar and pin illustrated at 36. A second horizontal' shaft 39, is mounted above the shaft 38 and is similarly provided with a bevel gear 40, meshing with a vbevel gear 41, coaxial with the shaft 35, and free with reference to said shaft. This latter gear is rigidly mounted upon a sleeve 42, which is revolubly carried by the beam 21 and is attached to and carries at its upper end a gear 43.- The shafts 38 and 39 are provided at their ends with bevel gears 44 and 45, respectively, such shafts may be conveniently carried within brackets 45, mounted upon` the underside of the beam 21. The gears 44 and 45 mesh respectively 'with the gears 19 and 20, which are rigidly mounted upon the stationary sleeve 16, as previously described. Y

The revoluble frame 34, rigidly supports a sleeve 46, which projects upwardly therefrom at an angle of 23gdegrees lto a vertical line'.`V This sleeve loosely carries a hub 47, which is formed intov a gear 48, adjacent its lower end. A sphere 49 is rigidly attached to the hub 48, adjacent its lower portion, and adjacent its upper portion pivots upon the sleeve 46.` This sphere is intended to represent the earth and is appropriately provided with a map upon its outer surface.

y The shaft 35 is rigidly attachedrto the frame f 'to A34. The outer end of the frame-carries a shaft 50, which at its lower end is provided with a rigidly attached pinion 51 meshing with a stationary gear 52, secured to the beam 21, as indica-ted at 53.l The upper end of the shaft has rigidly attached thereto ,a relativelylarge gear (54, which, through the medium of an idler 55, communicates its motion to aV gear :S6- such latter gear 56, meshing with-the gear 48 and serving therefore to rotate the sphere 49 as the framework 34 is slowly moved. If desired, a compass,

57` may be provided upon a projecting arm of the framework The pinion 51 is detachably joined to the shaft in any suitable manner, as by means of the slotted collar 51, so that it may be moved into and out of engagement therewith.

lVithin the sleeve 46 a relatively small shaft 58 is revolubly mounted and carriesat its lower end 'a gear 59, meshing with the gear 43 previously described. The upper end of the shaft rigidly'carries a bevel gear 60, meshing with` a bevel gear 61, said latter gear being carried by a shaft' mounted within a bracket 62, carried by the sleeve 46. The gear 61 is rigidly attached to the rod 63, which at one end carries a spherec64, de-V signed to represent the moon, andVv vat its other end a counterweight 65. A counterweight 66 of any desired type may be provided at the outer end of the shorter arm of the beam 21, so as to balance the mechanism carried by such: beam. Tt will be seen that the deviceconsists of a main balanced Vmechanism pivoted to the main axis of the apparatus and an auxiliary balanced Vmechanism pivot'ed to the outer end of the longer arm of the beam 21. Y y

The operation of the apparatus is as follows z-The motor 4 is started and controlled v by the snap switch 67, mounted in its base, and slowly rotates the sleeve 15-see Figure 3,-thereby7V slowly rotating the beam 21.

As this beam rotates, motion is communii cated to the shafts 38 and 39., which in turn.

drive the shaft 35 and thesleeve 42. As the sleeve 42 rotates, its gear 43 drives the smaller gear 59, which causes the sphere 64, representing the moon, toftravel about the sphere 49. The 'shaft 35 swings t-he framework 34 around, and causes the pinion 51 to rotate at a. more rapid rate. This motion is multiplied bythe gears 54, 55 and 56 and communicated to the pinion48, which is rigidly attached to the sphere 49, representing the earth, thereby rotating the earth about its axis. At the same time, however, the frame 34 rotates and causes the axis of the earth to assume different angular positions, and consequently causes the orbit ofy the sphere 64, to vary and to' be positioned at dierentplaces above and below'the plane representing the orbit ofthe earth about the sun or centering-point of the entire apparatus. The angular setting of the gear 61 is such that the sphere 64 travels in an orbit, which varies from 5 degrees above to 5 degrees below the orbit of the sphere 49, about the central point of the entire apparatus.

While these motions are being executed, the

beam 21 is slowly rotating about its Ypivot point, thereby causing the sphere 49'and its attac-hed parts to travel about Ythe central point of the entire apparatus, simulating the motion ofthe earth around thesun'. y

The electriclamp, Ytogether with its reflecfiao he may stop the motor and disengage the gear 36 from the gear 37, He may thereafter rotate the frame 34. V,This Vcauses the sphere 49 to rotate and similarly causes the ent seasons and the various, positions ofsphere 64 to revolve about said first-inentioned sphere. 1n this manner` the various positions ofthe earth correspond to differtlie moon may be quickly demonstrated. If the demonstrator desires,lhe may disengage the pinion 51 from the gear and also disengage the gear 36 from the gear 37 yby sliding such gears upwardly along their. respective shafts, as their hubs are slotted.y

and engage pins carried by l,their respective shafts. Under these conditions he may startthe motor and rotate the beam 21.- The sphere 49 Will therefore remain stationary, together with its'axis, with respect to the beam 21, and the demonstrator may therefore illustrate the absolute dependence of the seasons upon the angular setting of the earths axis with reference to a fixed line in space, for as the apparatus is operated iii the manner described, the angular setting of -the axis of the sphere 49 will not vary with reference to thebeam 21, and consequently se-asonal positions Will not be simulated.

It is obvious that other of the gears than those described may be detachably associated, so that other combinations may be effected.

When it is desired to ship or pack the tellurian, it lis merely necessary to lift the beam 21 upward. The'gears 45 and 44 disengage from the gears 19 and 20, and the gear 44 clearing the gear 20. rlhe sleeve Q2 lifts freely from the sleeve 15, tlieloose splined connection permitting this ready detaching. The parts, therefore, will be separated into tivo inain divisions, which may most readily be packed and shipped Without subjecting any of the parts to excessive strain due to rough handling Y It is to be noted that the electrical circuit for the lamp is immediately re-established When the parts again reposition, as.

the contact 25 engages the contacty 26 and establishes the circuit for the lamp, lt is also to be noted that the loose splined connection insures the correctV relative positioning of the parts. Y

to illustrate Y the seasons -in an extremely rapid manner,

It Will vbe seen-thatl a tellurian liasbeen v provided Which is electrically ,driven inja continuous and even manner,therebyl allowing the vdemonstrator to devoteliisentire attention to the elucidation of theV prob- 'lems which he is illustrating Without. giving any attention whatsoever to the mechanical operation of the apparatus.-V

It will further be seen that by the provision of the electric lamp, theV parallel rays of the sun are substantially'duplicated.

suitable scale illustrating the different seasons, .the months, the day ofthe month, the' signs Yofthe zodiac, or'othefsimilar data, and a pointer shown at 69, may-:be attached tothe bea-m 21 and co-operate W-itlithe scale Yto indicate mechanically Vthe-'exactphase orV position-of theA parts.

Although 'onespecific form of the inventail, it is to be understood that the invention If desired, 'the-fiat annularjsurface of Yr ythe housing center, may beprovided with a fsa" f tion has been described in considerablede-` i may take different forms .and such invention', therefore, isto be limited only as 'dei fined inthe appended claims.
