PROVISIONAL SPECIFICATION.
An Improved Means for Showing Different Local Times.
I JOHN WILLIS MASON, Artist, Author, and Drawer of Maps and Diagrams,
No. 2 Comiston Road, South Side, Edinburgh, Scotland, do hereby declare the
nature of this invention to be as follows:-
:-
A World Clock or Map Clock, for showing Universal, or World Time, at any place
on the globe, at any hour, by one dial which is printed, or painted, or impressed as a
radiated map of the world, which dial map is divided into twenty four hour lines, or
spaces, or meridians, (and these 24 spaces into smaller spaces, of 15 degrees each,)
which lines radiate from and revolve on the North Pole, as a centre, and like the
spokes of a wheel, or a wheel map. The said clock dial map moves round its
surrounding 24 hours circle, by clockwork, and when so revolving by its machinery,
or by hand. (as it can be moved onwards or set, like the hand of a clock, or watch,)
the hour opposite the meridian of any place or city, is the true time for that place, (or
very nearly so). The novelty of the Invention consists in radiating, or spreading out,
all the regions of the earth and sea, even to the South of the Equator, in said dial or
map, (no such map having ever been made or used before,) and in making the said
map to centre (like a wheel,) on the North Pole, and to revolve in a 24 hours circle,
so as to show constant world time.

COMPLETE SPECIFICATION.
An Improved Means for Showing Different Local Times.
JOHN WILLIS MASON, Artist, Author, and Drawer of Maps and Diagrams,
No. 2 Comiston Road, South Side, Edinburgh, Scotland, 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 :-
A World Clock, for showing Universal or World Time, at any place on the globe,
at any hour, by one dial, which is printed, or painted, or impressed, as a radiated
map of the world, which dial map is divided into twenty four hour lines, (or spaces,
or meridians, and these twenty four spaces into smaller spaces,) which lines radiate
from, and revolve on, the North Pole, as a centre, and like the spokes of a wheel, or a
wheel map; The said clock dial map moves round its surrounding 24 hours circle
by clockwork, and when so revolving by its machinery, or by hand (as it can be
moved onwards, or set, like the hand of a clock, or watch,) the hour opposite the
meridian of any place, or city, is the true time for that place. The novelty of the
Invention consists in radiating, or spreading out all the regions of the earth and sea
even to the south of the equator, in said dial, or map, (no such map having ever been
made or used before,) and in making the said map to centre (like a wheel) on the
North Pole, and to revolve in a 24 hours circle, so as to show constant world
time.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
Firstly. The discovery, invention, drawing and making of my said new radiated
map of the world.
Secondly. The application, to useful purpose, of said new radiated map, as "an

page_text: improved means for showing different local times" by placing it in the centre of a
24 hour and time circle, and by then causing the said map to revolve (by clockwork
or machinery,) within the said 24 hour and time circle, so that the said map then
shows, or points out, different local times, as it so revolves, on its centre, in the time
circle.
Thirdly. The fastening, fitting, or enclosing, constructing, and combining together,
the said
1st new radiated map,
2nd-the said 24 hour and time circle,
3rd the said clockwork, or machinery, into
4th suitable frames, glasses, cases, or boxes, so as to form,-
Fourthly.-One machine, or invention, called a World Clock, Universal Clock, or
Map Clock, and for which one machine, or World Clock, as never having been
drawn, made, invented, or combined, before, I now claim, as first and only Inventor
and discoverer thereof, and now request the grant of Letters Patent, to me, therefor
as witness my hand hereto, in continuation or completion of Complete Specification
Form C, No. 922389.
