PATRICK D. LAWLOR OF CARATUNK MAINE.
TELLURIAN.
SPECIFICATION forming part of Letters Patent No. dated May 17 .
Application filed August 20 1903. Serial No . (No mode])
To all whom it may concern:
Be it known that I PATRICK D. LAWLOR a subject of the King of Great Britain residing at Caratunk in the county of Somerset and
5 State of Maine have invented certain new and useful Improvements in Tellurians of which the following is a specification.
This invention has relation to apparatus for mechanically illustrating the phenomena of
zo night and day the seasons of the year the phases of the moon the earth's orbit the equation of time and other terrestrial and celestial occurrences.
For a full description of the invention and
15 the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.
20 While the essential and characteristic features of the invention are susceptible of modification still the preferred embodiment of the invention is illustrated in the accompanying drawings in which
25 Figure 1 is a front view of a tellurian em
. bodying the invention. Fig. 2 is a side elevation thereof showing the planetglobe Saturn and its supportingarm in dotted lines. Fig. 3 is a vertical central section of the tellurian
30 on a larger scale parts being broken away.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
35 Within the purview of the invention the apparatus may be arranged in any desired plane and the mountings for the operating parts may be of any construction according to the size and cost of the apparatus and the number of
40 globes embodied in its organization.
For the sake of illustration the apparatus is
shown in its simplest form and vertically dis
posed the framework comprising a stand 1
and frames 2 and 3 the latter receiving the
45 operatinggearing and the former supporting
the plate 4 to which the planisphere 5 is at
tached. The planisphere 5 is a plate or disk
having inscribed thereon the signs of the zo
diac the names of the calendar months the
50 Roman characters from "I" to "XII" in
elusive representing the hours of the day as commonly depicted upon the dial of a clock or like timepiece and any other matter desired to be called to attention. This planisphere and its support 4 are stationary.
The operatinggearing comprises the operatingshaft 6 companion shaft 7 pinion 8 secured to shaft 6 and in mesh with the gearwheel 9 secured to the shaft 7 and pinion 10secured to the opposite end portion of shaft 7 and 6o in mesh with gearwheel 11 secured to sleeve
12 loosely mounted upon the operatingshaft 6. The shaft 6 projects beyond the support 4 and planisphere 5 and has gearwheel 13 secured thereto which in turn is in mesh with coin 65 panion gearwheel 14 loosely mounted upon the journal 15 projected from the sup port 4 and set to one side of the shaft 6. Arms 16 and 17 project radially from the gearwheel 14 and are provided at their outer ends with globes M and 70 V representing the planets Mercury and Venus. These arms 16 and 17 may be of any relative length to approximate the proportionate distances of said planets from each other and from the sun and the earth. A sprocketgear
18 is loosely mounted upon the sleeve 12 and has a comparatively slow rotary movement imparted thereto corresponding approximately to the travel of the planets around the sun and arms 19 are secured at their inner 8o ends to the sprocketgear 18 and extend outward therefrom to a point beyond the planisphere and the earth's orbit and are provided at their outer ends with globes J S U and N representing respectively the planets Ju 8 piter Saturn Uranus and Neptune. These arms 19 may be of any determinate length to approximate the varying distances of the saic planets from the earth. The arms 16 and 17 are considerably shorter than the arms 19 90 since the planets Mercury and Venus travel within the earth's orbit whereas the planets represented by the globes attached to the arms
19 travel outside of the earth's orbit. An arm
20 is secured to the sleeve 12 so as to turn 95 therewith and is provided upon one end with a globe Ms representing the planet Mars and upon its opposite end with a globe E indicating the earth the globe Ms being preferably
of sufficient weight to counterbalance the parts i 00

applied to the opposite end of the arm 20 so that the apparatus may operate easily. A pointer 21 is attached to the end of the arm 20 adjacent to the globe Ms and extends over
5 the planisphere to indicate any matter thereon corresponding to the relative position of the earth with reference to the sun or other planets of the constellation.
A bearing 22 is provided at the end of the
10 arm 20 opposite to that carrying the planetglobe Ms and receives the shaft 23 to the opposite ends of which are attached respectively gearwheel 24 and sprocketgear 25 the latter being connected by sprocketchain 26 with
15 the sprocketgear 18. The gearwheel 24 is in mesh with a companion gearwheel 27. secured to shaft 28 carried by the arm 20 and supporting the earth and moon globes and their operatinggearing. A sprocketgear 29
20 is mounted upon the shaft 28 and is connected by sprocketchain 30 with a sprocketgear 31 secured to the powerdriven shaft6. Bevel gearwheels 32 and 33 are provided at the outer end of the shaft 28 and are in mesh with re
25 spectively the gearwheels 34 and 35the latter being connected with the axis 36 of the earthglobe E and the former having an arm 37 connected therewith and carrying the moonglobe Mn. The intermeshing gears 32 and
30 34 and 33 and 35 are separate and independent and rotate at different speeds whereby the globes Mn and E rotate at a variable speed corresponding to the planets which they represent.
35 Rotary motion being imparted to shaft 6
the gear elements 13 31 and 8 rotate in uni
son therewith and the sleeve 12 loosely mount
ed upon said shaft 6 is driven at a consider
ably slower speed by reason of the gearing 8
40 9 10 and 11. Hence the arm 20 and sprocket
gear 18 rotate at a much slower speed than the
elements 13 and 31. The gearing is so pro
portioned that in one revolution of the arm 20
the earthglobe E makes three hundred and
45 sixtyfive revolutions about its axis corre
sponding to the number of days and nights of a
calendar year. The globe Sn indicates the sun
the center of the solar system and is arranged
to one side of a prolongation of the shaft 6
50 whereby the orbit of the earth is eccentric to
the sun so as to represent the phenomena of
the seasons in conjunction with the inclination
of the axis of the earth to the ecliptic. By
inscribing the hours and minutes upon the planisphere to correspond to the dial of a:clock or timepiece and imparting a regular movement to the shaft 6 by means of a spring or weight as in an ordinary clockmovement the apparatus may be utilized as a timepiece as will be readily comprehended.
Having thus described the invention what is claimed as new is
1. ' In a tellurian the combination of a driveshaft a sleeve concentric with the driveshaft gearing connecting the sleeve and driveshaft for causing the two to rotate at different relative speeds an arm secured to said sleeve and provided with a shaft carrying the earthglobe a second shaft journaled to said arm a sprocketgear loosely mounted upon the said sleeve and connected to the second shaft mounted in said arm globecarrying arms attached to the sprocketgear loosely mounted upon said sleeve and gearing between the said driveshaft and the earthcarrying shaft substantially as specified.
2. In a tellurian the combination of a shaft and a sleeve concentrically mounted and adapted to be driven at different rates of speed a gearwheel in mesh with a companion gear secured to said shaft planetcarrying arms attached to said gearwheel an arm attached to the said sleeve a shaft journaled to said arm and geared to the driveshaft an earthglobe carried by the shaft attached to the said arm and gearing between the earthglobe and said shaft substantially as described.
3. In a tellurian the combination of a driveshaft a sleeve concentric therewith gearing connecting the driveshaft and sleeve for rotating them at different relative speeds an arm secured to said sleeve a shaft jonrnaled to one end of said arm and provided with an earthglobe gearing connecting said shaft with the driveshaft other gearing between the earthglobecarrying shaft and the aforementioned sleeve and a planetglobe at the opposite end of said arm to that carrying the earthglobe and serving as a counterbalance substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
