TELLURIAN.

SPECIFICATION forming part of Letters Patent No. 571,785, dated November 24, 1896. Application filed March 18, 1896- fiicrial No, 5835/73. (N model.)

To all whom, it may concernlie it known that 1, ROBERT hlOl/VERY, a citizen of the United. States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented a new and useful Tellurian, of which the following is a specification.

My invention relates to tellurians, and has for its object to provideasimpleand efficient construction and arrangement of parts whereby the movements of the earth and moon with relation to the sun to cause day and night, the change of seasons, the vernal and autumnal equinoxes, the perihelion and aphclion, the phases of the moon, the ebb and flow of the tide, and eclipses are illustrated, means being provided to maintain the axis of the earth. at its proper inclination in a uniform direction.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a telluria-n constructed in accordance with my invention. Fig. 2 is a partial longitudinal section of the same. Fig. 3 is a plan view of the cam-guide detached.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a base or platform which is elliptical in plan to correspond with the orbit of the earth, and arranged upon this base or platform concentric with a central standard 2 is a circular rack 3. A sliding frame consisting of upper and lower parallel bars i and 5, connected by vertical outer and inner braces 6 and 7, is mounted at its inner end upon the standard 2, and is provided at its outer end with a supporting or guide roll 8 to traverse a peripheral track 9 on the base or platform, said track consisting of a fiat band secured to the edge of the base and extending above the plane of the upper surface thereof. The bars l and are longitudinally slotted to form ways 10, in which are mounted journal-blocks 11, fitted for rotary movement upon reduced spindle portions 12 of the standard, whereby the frame is free to rotate around the standard as a center and at the same time is capable of longitudinal movement caused by the supporting or guide roll 8 traversing the track, the distance of the track from the standard varying to accord with the elliptical shape of the base. The upper bar 4 is extended beyond the standard to form a handle or grip 13, and the supporting or guide roll 8 is mounted upon a depending extension (3 of the outer brace (i. Mounted for rotation in suitable bearings formed in said extension o of the outer brace and in the corresponding. extension 7 of the inner brace is a horizontal shaft ll, upon which is feathered a pinion 15, meshing with the rack 23, said rack being provided with inner and outer guard webs or flanges 3 to maintain the pinion in operative relation therewith irrespective of the longitudinal or radial movement of the frame. In the construction illustrated the pinion 15 is provided with afeather .16 to 0perate in agroove 17.

The frame also supports at its outer end a vertical spindle 18, provided at its lower end with a bevel-gear 19, which meshes with a similar gear on the outer extremity of the shaft 14:, and is provided at its upper end with a gear 21 to mesh with a pinion 22 on the spindle 23 of the earth-globe 2i. This spindle of the earth-globe is mounted in bearings 25, arranged in inclined alinemeut and supported by a bracket 26, and the bracket is provided with a collar 27, which is removably fitted upon and secured to the upper reduced end of a tubular or hearing shaft 28, whereby said bracket and shaft are adapted for simultaneous rotation. This bearing-shaft is fitted at its upper and lower extremities in bearings formed in the outer extremities of the bars or arms 4E and 5 and performs the function of a bearing for the spindle 1S, and permanently fixed to said tubular shaft, which is thus disposed concentric with the said spindle, is a cylindrical shell 29, provided with acam-slot 30, said shell being spaced from the shaft 28 by means of upper and lower collars 31, which are rigidly secured in place.

ment to the swiveled bracket 26, which supports the earth-globe.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- I. In a tellurian, the combination with a fixed sun-globe, of a rotary frame, a bracket swivelcd upon the frame, an earth-globe having an inclined axis mounted upon the bracket and adapted to describe an orbit around the sun-globe, a fixed cam-guide, and a lever actuated by the cam-guide and operatively connected with said bracket to impart rotary motion to the bracket in accordance with the movement of the frame around its axis and preserve a uniform direction of inclination of the axis of the earth-globe, substantially as specified.
