PROVISIONAL SPECIFICATION.
A Metallic Topographical Map or Surface of Metal Representing
the Profile of the Earth or any part thereof, and Process of
Manufacturing same.
I, SAMUEL BEAVEN STEVENS of the Firm of Huntley Boorne & Stevens,
Tin Works, Reading, in the County of Berks, Manufacturer, do hereby declare
the nature of this invention to be as follows:--
This invention relates to a novel map, chart or plan formed from any suitable
sheet metal (such as tin-plate) in any suitable manner by stamping embossing or
otherwise impressing moulding or forming such sheet metal so as to represent
the general profile of the earth or any part thereof so that the mountains or
high ground stand out in relief from the low ground or general flat surfaces of
the ground represented, and having the names descriptions etc. of places districts etc.
plainly marked thereon or otherwise prepared colored decorated or marked as
desired for instance either printed by lithography zincography or other printing
methods direct, or by the transfer method.
My present invention is as follows:-
I take any suitable sheet metal of a good stamping quality (advantageously a
good quality of tin-plate is selected owing to its cheapness and suitability for the
purpose) and I first of all color same in any suitable manner (if desired the
mountains or mountainous parts are specially colored of a different color or colors.
from the valleys or other parts) for instance taking the case of the map of
England and Wales-the various counties may be variously colored and
delineated and the names thereof and of the towns etc. or any other names colors
or delineations clearly imprinted thereon while in the flat state.
Having thus prepared the map on a flat metallic surface of the character
described I next place the metal sheet thus prepared between suitable stamping
dies (specially constructed so as not to injure the surface thus prepared) which
dies are formed "male and "female to represent the profile of England and
Wales.
"
"
Having properly adjusted the metal sheet in position-these dies then stamp
up or force the metal surface to take their form and thus the mountains or
inequalities of the ground are all produced (in proper proportions) in this metal
sheet which thus is made to represent the exact profile of the country.
By this means I am enabled to produce a very cheap map or surface of metal
which besides being very durable (if not indestructible) will afford a simple and
practical means of teaching geography by showing the learner the actual position
relative height range etc. of the mountains of any part of the earth.
In a similar way and by similar or equivalent process I may produce metal
maps to show rivers lakes seas etc. by forming sunk surfaces in the metal to
represent same instead of the raised surfaces as above described to represent
mountains-or if desired a combination of both may be used.

A. Metallic Topographical Map or Surface of Metal Representing
the Profile of the Earth or any part thereof, and Process of
Manufacturing same.
I, SAMUEL BEAVEN STEVENS of the Firm of Huntley Boorne & Stevens,.
Tin Works, Reading, in the County of Berks, Manufacturer, do hereby declare
the nature of my invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention relates to a novel map chart or plan formed from any suitable
sheet metal (such as tin-plate) in any suitable manner by stamping embossing or
otherwise impressing moulding or forming such sheet metal so as to represent the
general profile of the earth or any part thereof so that the mountains or high
ground stand out in relief from the low ground or general flat surfaces of the
ground represented and having the names descriptions etc. of places districts etc.
plainly marked thereon or otherwise prepared coloured decorated or marked as
desired for instance either printed by lithography zincography or other printing
methods direct or by the transfer method.
My present invention is as follows:-
I take any suitable sheet metal of a good stamping quality (advantageously a
good quality of tin-plate is selected owing to its cheapness and suitability for the
purpose) and I first of all colour same in any suitable manner (if desired the
mountains or mountainous parts are specially coloured of a different colour or
colours from the valleys or other parts) for instance taking the case of the map
of England and Wales-the various counties may be variously coloured and
delineated and the names thereof and of the towns etc. or any other names colours
or delineations clearly imprinted thereon while in the flat state.
Having thus prepared the map on, a flat inetallic surface of the character
described next place the metal sheet thus prepared between suitable stamping
dies (specially constructed so as not to injure the surface thus prepared) which
dies are formed "male and female" to represent the profile of England and
Wales.
Having properly adjusted the metal sheet in position-these dies then stamp
up or force the nietal surface to take their form and thus the mountains or
inequalities of the ground are all produced (in proper proportions) in this metal
sheet which thus is made to represent the exact profile of the country.
By this means I am enabled to produce a very cheap map or surface of meta!
which besides being very durable (if not indestructible) will afford a simple aud
practical means of teaching geography by showing the learner the actual position
relative height range etc. of the mountains of any part of the earth.
In a similar way and by similar or equivalent process I may produce metal maps
to show rivers lakes seas etc. by forming sunk surfaces in the metal to represent
same instead of the raised surfaces as above described to represent mountains-or
if desired a combination of both may be used.
and
Referring to the sheet of drawings hereunto annexed :-
Fig. 1 represents plan of a metal profile map according to my present invention
Fig. 2 is section thereof on line A-B Fig. 1.
X is sheet of tin plate stamped or otherwise formed or embossed with raised and
depressed surfaces thereon as shown or in any other suitable manner according to
the profile of the country or part of the earth's surface to be shown.
Each end of the metal plate X may be turned down as shown at C to form a
support or stand on which to rest said map or on the other hand if desired the

page_text: end C may be turned up in the opposite direction to serve as a protection to the
mountain tops or high parts of the map for instance in packing for transit.
Or instead of this arrangement the ends of the metal plate X may be turned
over as at D to embrace and thereby hold a piece of millboard wood or other
suitable material E to form a backing to said map and take the "tinny" feeling
off the back of the map as well as serving to preserve same and prevent its
being bent.
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. Forming a topographical map or surface of metal with raised and depressed
surfaces to represent the profile of the earth or some part or parts thereof by first
colouring or otherwise suitably printing on or preparing the metal sheet in the flat
state and thereafter stamping or embossing said sheet in dies which impart the
desired conformation to same substantially in the manner and for the purposes
hereinbefore described.
2. A metal topographical map or surface of metal formed to represent the profile
of the earth or some part or parts thereof prepared and constructed substantially
in the manner and for the purposes hereinbefore described.
3. The improved map or surface of metal representing the profile of the earth
or some part or parts thereof substantially as and for the purposes hereinbefore
described and illustrated in the drawings hereunto annexed.
