Year: 1864

page_text: LETTERS PATENT to Elbert Perce, of the City, County, and State of
New York, United States of America, for the Invention of "IMPROVE-
MENTS IN GEOGRAPHICAL GLOBES AND ILLUSTRATIVE OBJECTS TO BE USED
THEREWITH."
Sealed the 27th June 1865; and dated the 30th December 1864.
PROVISIONAL SPECIFICATION left by the said Elbert Perce at the Office
of the Commissioners of Patents, with his Petition, on the 30th December
1864.
I, ELBERT PERCE, of the City, County, and State of New York, United
States of America, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN GEOGRAPHICAL GLOBES AND ILLUSTRATIVE OBJECTS TO BE USED
THEREWITH," to be as follows:-
The object of this Invention is to provide an available and convenient means
for temporarily attaching objects to the surface of a geographical globe, and by
this means to illustrate many of the natural laws and facts connected with the
globe on which we live.
The first part of this Invention consists in making a geographical globe in
whole or in part of a material capable of being permanently charged with
magnetism, or of being attracted by a permanent magnet, whereby I am enabled
to temporarily attach to the said geographical globe, objects illustrating the
physical and geographical features of the earth as herein-after more fully
set forth.

page_text: The second part of this Invention consists in making objects illustrative of
the geographical features of the earth in whole or in part, or with attachments
capable of being influenced by permanent magnetism so that the same may be
charged with such magnetism or attracted by a permanent magnetism in the
said geographical globe as herein-after more fully set forth.
The third part of this Invention consists in the combination with a
geographical globe made in whole or in part of a metallic substance capable
of being attracted by, or charged with permanent magnetism of objects illus-
trative of the geographical or physical features of the earth which are made of
or with parts or attachments of like material, either the geographical globe or
the objects being charged with permanent magnetism as herein-after more
fully set forth.
DESCRIPTION OF THE DRAWINGS.
In the accompanying Drawings, Fig. 1 is a side view of my improved
geographical globe with some objects attached in the manner already partially
described; Fig. 2 is an equatorial section; Fig. 3 is a perspective view of a
box containing the illustrative objects above mentioned, when the same are
not in use; Fig. 4 is a vertical longitudinal section of the same thing; Fig. 5
is a detached view of one of the illustrative objects.
A is the globe, the body of which I prefer to make of sheet iron or sheet steel
struck up into the proper form, and the parts soldered or otherwise attached
to each other. It may however be made of any other material, and covered
or coated with the magnetic oxide of iron to cause it to attract the illustrative
objects; or it may be cast hollow of cast iron, though the last mode of
making it is not recommended. This body formed by any of the means
described, or by any analogous means is then converted into a geographical
globe, by covering it with proper maps to represent the distinctions of the
surface of the earth in the usnal manner. I then prepare objects for illus-
trating the different physical and geographical features of the earth, which
objects I construct either in whole or in part of some metal capable of being
attracted by a permanent magnet or of being charged with permanent
magnetism, or attach pieces of such metal to them, this last being the mode
which I prefer. I make these pieces of such form as to be capable of being
converted into efficient permanent magnets for attaching illustrative objects to
the globe. I prefer to charge these objects with permanent magnetism as the
most available and convenient mode of accomplishing my purpose; but instead of
this, the body of the geographical globe itself may be charged with permanent:
magnetism if preferred. In case the illustrative objects are magnetized they

page_text: should be kept in a box with an iron or steel bottom when not in use to
prevent their losing their power. Figs. 3 and 4 represent such a box, in
which B is the iron or steel bottom referred to above. This box is divided
into compartments, each of which is large enough to contain one of the
illustrative objects which should be placed in it in such a manner that both
ends of the magnet shall rest on the iron plate.
It will be obvious from the foregoing description, that either the geo-
graphical globe or the illustrative objects must be charged with magnetism to
cause said objects to adhere to the globe when placed upon it, and it is also
clear that except as a matter of convenience and economy of construction it is
not material which of these is magnetized, in either case the result is the same,
and is produced by substantially the same means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Elbert Perce in the Great Seal Patent Office on the
29th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELBERT
PERCE, of the City, County, and State of New York, United States of America,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Elbert Perce, Her special licence that I, the said Elbert Perce,
my executors, administrators, and assigns, or such others as I, the said Elbert
Perce, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time, and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN GEOGRAPHICAL
GLOBES AND ILLUSTRATIVE OBJECTS TO BE USED THEREWITH," upon the condition
(amongst others) that I, the said Elbert Perce, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Elbert Perce, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol
lowing statement (that is to say):
The object of this Invention is to provide an available and convenient
means for temporarily attaching objects to the surface of a geographical
globe, and by this means to illustrate many of the natural laws and facts
connected with the globe on which we live.
The first part of this Invention consists in making a geographical globe in

The second part of this Invention consists in making objects illustrative of
the geographical features of the earth in whole, or in part, or with attachments
capable of being influenced by permanent magnetism so that the same may be
charged with such magnetism or attracted by a permanent magnet in the said
geographical globe, as herein-after more fully set forth.
The third part of this Invention consists in the combination with a
geographical globe made in whole or in part of a metallic substance capable of
being attracted by or charged with permanent magnetism of objects illustrative

DESCRIPTION OF THE DRAWINGS.
In the accompanying Drawings, Figure 1 represents a side view of my
improved geographical globe with some obiects attached in the manner alsood..

page_text: it is not recommended. This body formed by any of the means described or
by any analagous means is then converted into a geographical globe. by cover-
ing it with proper maps to represent the distinctions of the surface of the earth,
in the usual manner. I then prepare objects C for illustrating the different
physical and geographical features of the earth, which objects I construct either
in whole or in part of some metal capable of being attracted by a 'permanent
magnet, or of being charged with permanent magnetism, or attach pieces of
such metal to them, this last being the mode which I prefer. I make these
pieces of such form as to be capable of being converted into efficient permanent
magnets for attaching illustrative objects to the globe; I prefer to charge
these objects with permanent magnetism as the most available and convenient
mode of accomplishing my purpose, but instead of this, the body of the
geographical globe itself may be charged with permanent magnetism if
preferred. In case the illustrative objects are magnetized they should be kept
box with an iron or steel bottom when not in use to prevent their losing
their power. Figures 3 and 4 represent such a box, in which B is the iron or
steel bottom referred to above. This box is divided into compartments, each
of which is large enough to contain one of the illustrative objects which
should be placed in it in such a manner that both ends of the magnet shall rest
on the iron plate.
It will be obvious from the foregoing description that either the geographical
globe or the illustrative objects inust be charged with magnetism to cause the
said objects to adhere to the globe when placed upon it, and it is also clear
that except as a matter of convenience and economy of construction, it is not
material which of these is magnetized, in either case the result is the same,
and is produced by substantially the same means.

with parts of such metallic substance, either the geographical globe or the
illustrative objects being made capable by permanent magnetism of attracting
the other, substantially as herein above set forth.
In witness whereof, I, the said Elbert Perce, have hereunto set my
hand and seal, this Eighteenth day of May One thousand eight
'hundred and sixty-five.
