Improvements in the Manufacture of Printed Works, especially
Maps, in Different Colors, on Caoutchouc or Material Impregnated
or Coated with Caoutchouc.
I, CARL BUCHMUELLER, of the Town of Kohlgrub, near Munich, in the Kingdom
of Bavaria and German Empire, Lieutenant in the Bavarian Army, do hereby declare
the nature of my said invention to be as follows:-
My invention relates to improvements in the manufacture of printed works and
especially maps in one or various colors on caoutchouc, india rubber, or on cambric,
linen, silk and other fabric or material impregnated or coated with india rubber or
caoutchouc.
Up to the present time paper of various kinds, such as hemp or maize paper or
cardboard, has been used for producing charts and maps of all kinds for military
purposes, surveyors, tourists and other persons, but such charts or maps are not durable
enough to stand the wear and tear they are subjected to and especially by soldiers,
workmen and the like, and besides this such charts or maps suffer severely from the
influence of rain, snow or fog, so that it has become necessary to discover a material
for the production of such said prints, which will not only be capable of receiving and
retaining the matter printed on the same, but will stand all ordinary wear and tear
and also withstand the influences of damp, rain, snow and other climatic influences.
Appropriate materials for this purpose are cambric, linen, silk or other fabric which
has been previously impregnated or coated with caoutchouc.
Maps and charts can be produced on such material with the same sharpness and
clearness as on the ordinary materials now in use but charts, maps and the like
produced or printed on the abovenamed impregnated material are of a durability
hitherto unknown as they are able to withstand all climatic influences and also heavy
wear and tear.
The production of such printed works is divided into two operations, viz., the
manufacture of the material, and the process of printing. For manufacturing the
material, for which no claim is made, I take cambric, linen, silk or other fabric,
provide the same on both sides with a very thin. layer of india rubber and vulcanize
the same in well known manner. Before the so prepared material is used for printing
purposes, it must be well rolled by being passed between appropriate rollers, and so
extended that a further stretching of the material, even when repeatedly passed
through the printing press, cannot take place but will always remain in the same
condition; the said material may be applied to stiff paper or cardboard so as to
avoid all stretching and the formation of folds during the printing and, when the
printing process is finished, can be removed from such said stiff or rigid layer or
backing.
The chart, map or other matter can be printed on the so prepared material in the
customary manner. My improvements consist principally in adapting the caout-
choucized material for use in the manufacture of charts or maps, whereby I attain the
following advantages.
The charts or maps made according to my improved system can be readily stored,
he drawing and other printed matter will be perfectly retained, even when the said
charts or maps are folded tightly and subjected to pressure; they can be readily cleaned
by washing with water and can be readily reproduced; the material can be printed on
both sides and need not be applied to a linen backing and the charts can be colored
by mixing alum with the colors employed for such purpose. A further very great
dvantage is that the line of route for troops and the positions occupied or to be
ccupied by them can be indicated or drawn on such chart or map, and, when desired,
TDC1

taken place since the printing of the chart or map, such, for instance, the cutting
down of a wood, alterations of the course of roads and the like, new buildings and so
on, can be readily indicated by washing out the old marks and inserting the
corrections.
Another great advantage lies in the dull gray color which is much more endurable
to the eyes when the maps are used out doors and subjected to the rays of the sun.
As the printed matter can be removed from the surface of my improved charts or
maps by means of turpentine or alcohol it will be evident that the said material can
again be subjected to the printing process without injury.

Improvements in the Manufacture of Printed Works, especially
Maps, in Different Colors, on Caoutchouc or Material Impregnated
or Coated with Caoutchouc.
I, CARL BUCHMÜLLER of Kollgrub, near Munich in the Kingdom of Bavaria
and German Empire, Lieutenant in the Bavarian Army, 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 following statement :-
My invention relates to improvements in the manufacture of printed works, and
especially maps, in one or various colors, on caoutchouc, india rubber, or on cambric,
linen, silk, and other fabric, or material, impregnated or coated with india rubber or
caoutchouc..
Up to the present time paper of various kinds, such as hemp, or maize paper, or
cardboard, has been used for producing charts and maps of all kinds, for military
purposes, surveyors, tourists, and other persons; but such charts or maps are not
durable enough to stand the wear and tear they are subjected to, and especially by
soldiers, workinen, and the like; and besides this such charts or maps suffer severely
from the influence of rain, snow, or fog, so that it has become necessary to discover a
material for the production of such prints, which will not only be capable of receiving
and retaining the matter printed on the same, but will stand all ordinary wear and
tear, and also withstand the influences of damp, rain, snow and other climatic
influences. Appropriate materials for this purpose are cambric, linen, silk, or other
fabric which has been previously impregnated or coated with caoutchouc.
Maps and charts can be produced on such material, with the same sharpness and
clearness as on the ordinary materials now in use, but charts, maps, and the like,
produced or printed on the abovenamed impregnated material, are of a durability
hitherto unknown, as they are able to withstand all climatic influences and also heavy
wear and tear.
The production of such printed works is divided into two operations, viz., the manu-
facture of the material, and the process of printing. For manufacturing the material,
for which no claim is made, I take cambric, linen, silk or other fabric; provide the
same on both sides with a very thin layer of india rubber, and vulcanize the same in
any well known manner. Before the material so prepared is used for printing
purposes, it must be well rolled, by being passed between appropriate rollers, and so
extended that a further stretching of the material, even when repeatedly passed
through the printing press, cannot take place but will always remain in the same
condition; the said material may be applied to stiff paper or cardboard, so as to
avoid all stretching and the formation of folds during the printing, and, when the
printing process is finished, it can be removed from such stiff or rigid layer or
backing.
The chart, map, or other matter, can be printed on the prepared material in the

page_text: customary manner. My improvements consist principally in adapting the caout-
choucized material for use in the manufacture of charts or maps, whereby I attain the
following advantages
:-
The charts or maps, made according to my improved system, can be readily stored,
the drawing and other printed matter will be perfectly retained, even when the said
charts or maps are folded tightly and subjected to pressure; they can be readily
cleaned by washing with water and can be readily reproduced; the material can be
printed on both sides, and need not be applied to a linen backing, and the charts can
be colored by mixing alum with the colors employed for such purpose. A further
very great advantage is that the line of route for troops, and the positions occupied
or to be occupied by them, can be indicated or drawn on such chart or map, and,
when desired, can be removed by washing with ordinary water. Any alterations
which may have taken place since the printing of the chart or map, such, for instance,
as the cutting down of a wood, alterations of the course of roads, and the like, new
buildings, and so on, can be readily indicated by washing out the old marks and
inserting the corrections.
Another great advantage lies in the dull gray color, which is much more endurable
to the eyes, when the maps are used out doors and subjected to the rays of the
sun. As the printed matter can be removed from the surface of my improved
charts or maps by means of turpentine or alcohol, it will be evident that the said
material can again be subjected to the printing process without injury.
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 :-
1. The application and use of caoutchouc or caoutchoucized substances, as materials
for receiving printed matter, more especially maps, in various colors, substantially as
and for the purposes herein before described.
2. The improvements in the manufacture of printed works, especially maps, in
different colors, on caoutchouc or caoutchoucized materials, substantially as herein
before described.
