In der verlängerten Richtung der von oben herein bis zum Mittelpunkt der Glaskugel gehenden schiefen Sonnenaxe s wird das Fufsgestell von einer Axe a gleicher Richtung durchbrochen, welche sich der Führung wegen in einem Messingcylinderchen b bewegt. Beinahe unmittelbar über dem Fufsgestell dient diese Axe als Mittelpunkt einer festen, etwas elliptisch geformten Blechscheibe c, die genau horizontal liegt und deren Aufsenrand nach oben und innen abgeschrägt ist. Oberhalb dieser Scheibe nun setzt sich die genannte Hauptaxe α nicht ganz bis zu der Glaskugelöffnung fort; durch ihre Neigung zur Blechscheibe c bildet sie einen Winkel von etwa 670. An ihrem oberen Ende ist rechtwinklig zu ihr der Hebel d befestigt, welcher die cylindrische Führung e der Erdaxe / trägt. Diese verläuft parallel der verlängert gedachten Sonnenaxe und wird um dieselbe mittelst Drehung des Handgriffes g getragen, welcher innerhalb der drei Füfse des Gestelles seitlich an das Ende der hier herabgehenden Hauptaxe α befestigt ist. In the extended direction of the inclined sun axis s going from above to the center of the glass ball, the base frame is broken through by an axis a in the same direction, which moves in a brass cylinder b for the sake of guidance. Almost immediately above the pedestal, this axis serves as the center of a solid, somewhat elliptically shaped sheet metal disc c, which lies exactly horizontally and whose outer edge is beveled upwards and inwards. Above this disk, the main axis α mentioned does not continue right up to the opening of the glass sphere; due to its inclination towards the sheet metal disc c , it forms an angle of approximately 67 ° . At its upper end, the lever d is attached at right angles to it, which carries the cylindrical guide e of the earth axis /. This runs parallel to the elongated sun axis and is carried around the same by turning the handle g , which is attached within the three feet of the frame to the side of the end of the main axis α descending here.
Damit nun die Erdkugel / sich um ihre eigene Axe drehe, endigt diese ihre Axe f in eine kleine Frictionsscheibe //, die dann bei der Fortbewegung der Erdaxe durch Reibung an der Scheibe c zur Umdrehung gebracht wird.So that the globe / turns around its own axis, this ends its axis f in a small friction disk //, which is then made to rotate by friction on disk c when the earth axis moves forward.
Da endlich die Erdaxe (ein Stahlstift) bei der Drehung der mittelst des Hebels d und der Führung e sie tragenden Hauptaxe α nicht von der wechselnden höheren und niederen Stellung ihrer Führung e abhängt, sondern durch ihre eigene Schwere und die der Erdkugel i an dem Rand der Blechscheibe fortläuft, so ist die schwache Ellipse der Erdkugelbahn völlig parallel dem Rand der Blechscheibe und so die Ekliptikebene völlig correct zur anschaulichen Darstellung zu bringen.Finally, since the axis of the earth (a steel pin) during the rotation of the main axis α, which carries it by means of the lever d and the guide e, does not depend on the alternating higher and lower position of its guide e , but on its own gravity and that of the globe i at the edge the sheet metal disk continues, then the weak ellipse of the globe orbit is completely parallel to the edge of the sheet metal disk and thus the ecliptic plane is to be brought completely correct to the vivid representation.
Die Glaskugel ruht auf drei Füfsen k, die mit den drei Gestellfüfsen zusammengeschraubt werden.The glass ball rests on three feet k, which are screwed together with the three frame feet.
