WALTER F. AGNEW, OF FORT WORTH, TEXAS.
WORLD-CHRONOMETER.Specification of Letters Patent.
Patented Dec. 29,1914.
Application filed December 23, 1912. Serial No. 738,207.
To all whom it may concern:
Be it known that I, WALTER F. AGNEW, a
citizen of the United States, residing at
Fort Worth, in the county of Tarrant and
5 State of Texas, have invented certain new
and useful Improvements in World-Chro-
nometers, of which the following is a speci-
fication.
My invention relates to a new and useful
10 world chronometer, and its object is to pro-
vide a time indicating device which when
set into operation will indicate the time of
day or night at any place upon the earth's
surface.
15 The object of the invention more specifi-
cally stated is to provide a time indicating
device comprising a globe having its surface
mapped to indicate the earth's surface, said
globe being subjected by clock work to a
20 rotation producing one complete revolution
of the globe in twenty-four hours, a circular
scale concentric with the axis of rotation of
the globe being supported in some suitable
manner closely adjacent to a diametrical
25 portion of the globe, the scale being divided
into twenty-four units representing hours,
which units are subdivided to indicate
minutes.
A further object of the invention is to
to mount the apparatus just described upon a
pedestal upon the sides of which advertising
matter may be carried, and to provide a
twenty-four hour dial upon the top surface
of said pedestal which dial will be traveled
85 by a pointer carried by the spindle upon
which the globe is surmounted.
Finally the object of the invention is to
provide a device of the character described
that will be simple, durable and instructive
40 in its nature and will be a valuable advertis-
ing medium.
With these and various other objects in
view, my invention has relation to certain
novel features of the construction and opera-
.45 tion, an example of which is described in the
following specification; and illustrated in
the accompanying drawings, wherein:
Figure 1 is a view of the invention in side
elevation, the pedestal upon which the ro-
so toting globe is surmounted being broken
away in its upper part to make visible a
clockwork contained within said pedestal for
communicating rotation to the globe. Fig.
2 is an enlarged view showing the top sur-
55 face of said pedestal, this view having the
nature of a section taken upon the line x--xof Fig. 1 looking downwardly. Fig. 3 is a
view of the device in side elevation showing
a door forming one of the sides of the
pedestal in an open position giving access to 60
the pedestal interior.
Referring now more particularly to the
drawings wherein like reference characters
designate similar parts in all the figures, the
numeral 1 denotes a hollow pedestal, which 65
will preferably be provided with eight sides
inclined slightly outward from top to bottom
of the pedestal. One of these sides may
serve as a door giving access of the interior
of the pedestal, said door being denoted by 70
the numeral 2 and being provided with
hinges 3. Within the upper portion of said
pedestal there is provided a clockwork 4
mounted upon a horizontal partition 5. The
clockwork 4 is adapted to communicate a 75
constant clockwise rotation to a vertical
spindle 6 passing centrally through the top
7 of the pedestal, the speed of this rotation
being such as to produce one revolution
every twenty-four hours. The top extremity 80
of the spindle 6 carries a large globe 8 hav-
ing its surface mapped to represent the
earth's surface. This globe which is spaced
a short distance above the top surface of the
pedestal is inclosed within a glass casing 85
having its top of semicircular form and con-
centric with the globe from the surface of
which said semicircular top is slightly
spaced. The top surface of the pedestal
carries a dial graduated into twenty-four go
main divisions representing hours and into
subdivisions representing minutes, one-half
of the dial including divisions extending
from one to twelve will be stained a darker
color than the remaining portion of the dial, 95
the light half of the dial being marked
"Day" and the dark half being marked
"Night ". Within the dial there will also
be preferably contained the words "Rail-
road time ". In order that the figures of the ioo
dial and the words contained within the
dial circle may be more readily observed, the
top surface of the pedestal is made to form
a cone of very gradual inclination. Upon
the spindle 6 between the top surface of the 105
pedestal and the globe 8, a pointer 11 is
mounted fast, the extremity of said pointer
being adapted to travel above the graduated
dial units. The pointer 11 and the scale 10
in conjunction thus serve to quickly indicate 110
to any observer the time of day or night at
the place where the device is set up.1,122,352.
