CHARLES B. MARTINOF PORTLAND, OREGON, ASSIGNOR OF TEN ONE- HUNDREDTHS TO J. FRED KENNEDY, OF PORTLAND, OREGON.
TELLURIAN.
Specification of Letters Patent.
Patented Mayz2 1, 1907.
To all whom it may concern.-
.Be it known that I, CHARLES B. MARTIN, a citizen of the United States, and aresident of Portland, in the county of Multnomah and State otOregon, have invented a new and Improved Tellurian, of which the following is a full, clear, and exact description.
The invention relates to educational appliances, and its object is to provide a new and improved tellurian arranged to demonstrate the various relations of the globe relative to the sun and moon, with a view to explain the different times, seasons, moons phases, tides, etc.
The invention consists of novel features and parts and combinationsfloi the same, which will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the tellurian; Fig. 2 is an enlarged side elevation of a portion of the ring of the demonstrating device indicating on the zodiac ring of the globe; Fig. 3 is aperspective view of the demonstrating device removed from the globe; Fig. 4 is an enlarged plan view of the dial for indicating the phases of the moon, and tides, and
Fig. 5 is a like view of the moon support in position on the said dial.
The sphere A of an ordinary globe has its axis 13' secured at the lower end in a suitable stand O carrying a ring D representing the ecliptic and provided with the usual graduations of the zodiac. On the globe is removably held a demonstrating device consisting essentially of a graduated ring E mounted to turn on the zodiac ring D, the representation of the sun F having a support G attached to the graduated ring E'. The representation of the moon H is held on a supporting rod I provided with a disk I mounted to turn on a pivot J secured centrally on a dial K attached to the top or middle portion of a semiring L fastened at its ends to the graduated ring E at diametrically opposite points thereof, the semi-ring L standing at right angles to the graduated ring E. The graduated ring E is provided at its upper edge with a graduation E indicating the hours for a whole day, and on the lower edge of the said ring E is arranged a graduation E indicating the degrees. The ring E is provided with a slot E (see Fig. 2) extending to the left and right at the zero point of the graduation E so that the graduation representing the zo- .diac on the ring D can be readily seen.
The representation of the sun F is arranged centrally in a horizontal plane containing the upper edge of the ring E, and the representa tion of the moon H is similarly arranged in the said plane, but is capable of being swung around independent of the turning of the ring E on the ring D. The disk I is provided with apertures I (see Fig. 5) for reading the graduations on the dial K as the rep resentation of the moon is swung around, it being understood that the graduations on the dial K represent the different phases of the moon as well as the tides. The semiring L is slotted in the direction of its length so as to permit of locating any point of the sphere A at the slot, it being understood that the terminals of the semi-ring L connect with the ring E at six hours of the graduation E. Now by the arrangement described the entire demonstrating device can be turned around on the globe on account of the ring E being mounted to turn on the ring D, and the representation of the moon H can be swung independently around the sphere A.
Thus by the arrangement described the existing conditions of our earth, sun and moon can be readily demonstrated at the same time the correct time can be given on any part of our globe.
It will also be noticed that by the arrangement described the solar day, the sideral day, the lunar day, the month, days of the month, the signs of the zodiac, the seasons, degrees, the globes orbit, the equinoctial days, and the summer and winter solstices can be readily shown, at the same time giving day and night and the variations of the length of day and night from day to day.
In turning the representation of the moon H around the earth, the number of degrees traveled by the moon in a single day are given, at the same time the several phases of the moon as well as the time and variations of the tides and all their phases readily appear to the observer.
Having thus described my invention, I
globe and a zodiac ring, of a demonstrating device comprising a graduated ring turnable on the zodiac ring, a sun supported by the said graduated ring, a semi-ring attached to the graduated ring at diametrically opposite points and standing at right angles thereto, and a moon having a support mounted to turn at the top of the said semi-ring.
2. In a tellurian, the combination with a globe and a zodiac ring, of a demonstrating device comprising a graduated ring turnable on the zodiac ring, a sun supported by the said graduated ring, a semi-ring attached to the graduated ring at diametrically opposite points and standing at right angles thereto, a moon-phase and tide dial fixed on the top of the said semi-ring, and a moon having a support provided with an apertured disk mounted to turn centrally on the said dial.
8. In a tellurian, the combination with a globe and a zodiac ring, of a demonstrating device comprising a graduated ring turnable on the zodiac ring, the said graduated ring having an hour graduation, a degree graduation and a slot for viewing the graduation on the said zodiac ring, a sun supported by the said graduated ring, a semi-ring attached to the graduated ring at diametrically opposite points and standing at right angles thereto,
and a moon having a support mounted to v turn at the top of the said semi-ring.
4. A demonstrating device for removable attachment to a globe comprising a ring having an hour graduation, a degree graduation, and a slot at zero of the degree graduation, a sun, and a support for the same and secured to the said ring to support the sun centrally in the horizontal plane of the ring, and centrally in a plane passing through zero of the said degree graduation.
5. A demonstrating device for removable attachment to a globe comprising a ring representing the ecliptic, a semi-ring secured at its ends to the said ecliptic ring and at diametrically opposite points thereof, a dial fixed to the top of the said semi-ring and graduated to indicate the moons phases and tides, and moon, and a suspending rod for the said moon and provided with a disk mounted to turn centrally on the said dial, the disk having apertures for register with the said dial graduations.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES B. MARTIN.
