PROVISIONAL SPECIFICATION.
A New or Improved Tellurion.
I JOHN BAKER FISHER, Beach Street, Deal, Kent, Engineer do hereby declare
the nature of this invention to be as follows:-
:―
A machine to illustrate the diurnal motion of the earth-the seasons of the year
and their relative lengths of day and night, the position of the sun in the zodiac in
the different months, and if desirable the relative solar time at all parts of the
earth-constructed of the following details.-A stand mounted with a ring or disc,
tabulated to show the zodiacal signs and the months of the year,-and with an
oblique spindle loose or fixed on which spindle is mounted fixed or loose a globe
representing the earth-the said stand being also mounted with a loose ring or bow
parallel to the ecliptic and at right angles to a bow, mounted in or forming part of
the aforesaid loose ring or bow, vertical with the ecliptic and concentric with the
globe representing the earth,-the bow in the plane vertical to the ecliptic to carry
if desirable a ring which lying in the plane of the ecliptic shall be marked to
indicate the relative time at all meridians. The said loose ring or bow to carry a
small ball, indicating the relative position of the sun, wherewith likewise the said
loose ring or bow may be manipulated,-the said loose ring or bow to be if
desirable likewise capable of conveying by teeth or friction a rotatory motion to
the sphere representing the earth.

COMPLETE SPECIFICATION.
A New or Improved Tellurion.
I JOHN BAKER FISHER of Beach Street, Deal, Kent, Engineer do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to tellurions and has for its object to produce a simple
apparatus to exemplify the diurnal motion of the earth, the seasons of the year,
the position of the sun in the zodiac, and the relative solar time at all parts of the
earth.
Referring to the accompanying sheet of illustrative drawings-
Figure 1 represents the arrangement of my invention in end elevation.
Figure 2 is a sectional side elevation.
Figure 3 is a plan of a time ring and of a ring mounted with a bow and with a
sphere.
Figure 4 is a plan of a month and zodiacal sign ring, and of a disc around which
the ring mounted with a bow and with a sphere may be moved.
A base a is fitted with a fixed disc band with a fixed spindle c on which a hollow
spindle d is caused to revolve by friction or otherwise by the revolution of the
the hollow
ring e, causing a hollow spindle f also to revolve by friction at g,
spindle f being a fixture in sphere h which represents the earth; if desirable the
hollow spindles f and d may be made in one spindle, or the spindle c may be made
loose in the stand a, and caused to revolve in like manner as before described by the
revolving of the ring e.
k is a small sphere, serving to indicate the position of the sun in the zodiac

page_text: throughout the year, and is mounted on a stem which stem may be either fixed or
loose in the ring e.
The bow m is mounted in or on the ring e diametrically and at right angles to
the ring e, and is intended to demark day from night. n is a time ring which may
be sustained at the plane of the ecliptic of the tellurion on the bow m if desirable
to show the relative time on the meridians. o is a printed paper ring made to
adhere to the stand a, and serves with the sphere k and the bow m to indicate the
position of the sun in the zodiac and the months of the year.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is in tellurions the combined use of the following details which are substantially
described with reference to the accompanying drawings:
A stand to which a loose ring is fitted in such manner that the said ring can be
readily and truly rotated in a plane parallel to the ecliptic of the tellurion around
a center maintained by the said stand;-the said stand to be also fitted with a
spindle or spindles carrying a sphere or spheroid representing the earth the equator
of which sphere or spheroid shall be caused to revolve in the plane of the equator
of the tellurion by friction or otherwise within the said ring and by the rotation of
the said ring.
