Patentiert im Deutschen Reiche vom 4. Juni 1907 ab.Patented in the German Empire on June 4, 1907.

Gegenstand der Erfindung ist eine Vorrichtung, welche die Änderungen des Datums beim Überschreiten der Datumgrenze veranschaulicht. The invention relates to a device which changes the date illustrated when crossing the date line.

Diese Vorrichtung ist in Fig. ι bis 6 in zwei Ausführungsformen dargestellt.This device is shown in Fig. 1 to 6 in two embodiments.

Fig. ι zeigt eine perspektivische Ansicht, Fig. 2 einen Querschnitt der Vorrichtung undFig. Ι shows a perspective view, Fig. 2 shows a cross section of the device and

ίο Fig. 3 schematisch eine Seitenansicht des Räderwerkes.ίο Fig. 3 schematically shows a side view of the Gear train.

Fig. 4, 5, 6 zeigen eine andere Ausführungsform der Vorrichtung im Querschnitt und zwei Längsschnitten.4, 5, 6 show another embodiment of the device in cross section and two longitudinal sections.

Geht man von einem Punkte Europas genau i8o° nach Osten, so ergibt sich ein Zeitunterschied von 12 Stunden. Ist es also an einem Punkte in Europa am 1. Juni 8 Uhr morgens, so ist es auf dem Punkte, der i8o° östlich liegt, 8 Uhr abends. Geht man aber i8o° nach Westen, so gelangt man zu demselben Punkte wie vorher, muß aber jetzt hier den 31. Mai 8 Uhr abends zählen. Da man nun bekanntlich den auf der jenseitigen Erdhälfte liegenden Halbmeridian von Greenwich als sogenannte nautische Datumgrenze annimmt, so wird man, wenn man diese Linie von Westen nach Osten überschreitet, den betreffenden Tag doppelt zählen.; fährt man dagegen von Osten nach Westen über diese Linie, so wird man einen Tag seines Kalenders ausfallen lassen.If one goes exactly 18o ° to the east from a point in Europe, there is a time difference of 12 hours. So it is at one point in Europe on June 1st, 8am in the morning, it is eight o'clock in the evening at the point located 180 degrees east. But you go 180 ° to the west, one arrives at the same point as before, but must now here count May 31st at 8 p.m. Since one is now known to be on the other side Half of the earth lying half-meridian of Greenwich as the so-called nautical date line suppose that if one crosses this line from west to east one becomes the count double the day concerned .; on the other hand, one drives from east to west over this Line, you will skip a day of your calendar.

Es wird daher derjenige, welcher von Osten nach Westen um die Erde reist, scheinbar einen Tag verlieren, und derjenige, welcher von Westen nach Osten diese Reise macht, einen Tag gewinnen.He who travels around the earth from east to west therefore becomes apparent lose a day, and the one who makes this journey from west to east, win a day.

Die Erfindung betrifft nun eine Vorrichtung, welche die Bewegung eines nach Osten oder Westen um die Erdkugel herum reisenden Mannes beim Drehen der die Erde darstellenden Kugel mechanisch wiedergibt. Die Erde wird durch die beiden durch einen Schlitz etwas voneinander getrennten Halbkugeln α und O₁ dargestellt. Die Platte b soll die Sonne bedeuten. Die Halbkugeln α und α_λ sitzen fest auf der Achse c. Die Kugelhälften drehen sich stets gemeinsam beim Bewegen der Kurbel. Die Kugel kann in einem entsprechenden Gestell oder Kasten gelagert sein.The invention now relates to a device which mechanically reproduces the movement of a man traveling to the east or west around the globe while rotating the globe representing the earth. The earth is represented by the two hemispheres α and O _{1, which} are slightly separated from one another by a slit. The plate b should mean the sun. The hemispheres α and α _λ sit firmly on the axis c. The halves of the ball always rotate together when the crank is moved. The ball can be stored in a corresponding frame or box.

Auf der Achse c sitzen zwei Paare Zahnräder, von denen je eines fest mit der Achse verbunden und je eines lose auf der Achse sitzt. Die Räder/und i sind die festsitzenden Räder, während die Räder g und h lose laufen. Je ein Räderpaar kann mit einem dritten Zahnrad k bzw. / von beliebig vielen Zähnen verbunden werden. Die Räder/ und g haben gleichen Durchmesser aber verschiedene Zähne- ' zahl, und zwar soll das Rad / mehr Zähne als das Rad g haben. Ebenso haben die Räder i und h gleichen Durchmesser aber verschiedene Zähnezahl, und es soll Rad i einige Zähne weniger als Rad h haben. Dadurch bilden die Räder g, f und k und die Räder h, i und I je ein Differentialgetriebe, bei welchem Rad g gegen Rad/ voreilt und Rad h gegen Rad i zurückbleibt. Befestigt man also anOn the axis c there are two pairs of gears, one of which is firmly connected to the axis and one is loosely attached to the axis. The wheels / and i are the stuck wheels, while the wheels g and h run loose. One pair of wheels can be connected to a third gear k or / from any number of teeth. The wheels / and g have the same diameter but a different number of teeth, namely the wheel / should have more teeth than the wheel g . Likewise, gears i and h have the same diameter but different numbers of teeth, and gear i should have a few fewer teeth than gear h . As a result, wheels g, f and k and wheels h, i and I each form a differential gear, in which wheel g leads against wheel / and wheel h lags behind wheel i. So one attaches to

Claims

the wheels g and h struts m and n, which are occupied with figures ο and ρ, which look out of the slot e, the figure ο will advance slightly with each revolution of the ball towards its previous position and the figure ρ will lag a little behind. Choose e.g. B. for wheel / 40 teeth and wheel g 38 teeth, then wheel g will lead by 1J19 of its circumference with each revolution of the latter, so figure 0 will also be ahead of 1J19 of the circumference of the ball on the latter. So you will have to turn the ball 10 times before the figure has returned to its starting point. This movement makes it easy to explain that point q on the sphere has 19 times the noon sun, while Figure 0 sees 20 noon. Conversely, the figure ρ will see 18 noon at 19 revolutions of the ball, if one gives the wheel i 36 teeth and the wheel h 38 teeth, because wheel h lags behind the latter with each revolution of the wheel i by 1J19 of the circumference. In order to be able to let the figures ρ and 0 make their journey around the sphere individually or independently of each other, the wheels k and I are arranged on supports r and s, which can be moved against the wheel pairs f, g and h, i, like in Fig. 3 is indicated. For this purpose, these supports r and s sit on wooden slides t and u. So you can switch off each of the two figures ο and ρ from the movement as soon as you disengage wheel / or k. 4 to 6 show another type of differential gear for moving the figure on the circumference of the sphere. The figure ν sits in a guide w that runs around the ball χ. The figure is attached to a cord y that goes around the ball and is firmly connected to the fixed axis \ through an opening y1 in the ball. If you now turn the ball χ by moving the crank X1 in the direction of the arrows drawn (Fig. 5 and 6), the string will wind up on the stationary axis ι, and the figure ν will, depending on the string on the right (Fig . 5) or on the left (Fig. 6) is placed around the ball, against the movement of the ball with each revolution by a bit behind or ahead, namely by a length that corresponds to the tendon piece wound on the axis \ during each revolution is equivalent to.
