The Displaying of Maps, Charts, Diagrams, Ethnographic, Heraldic,
Genealogical, Statistical, Scientific, and similar Illustrations in
Continuous Form.
I CHARLES HENRY COPE of Wigginton Park, Tamworth, Staffordshire retired
Civil Engineer & now of no occupation, do hereby declare the nature of this invention
to be as follows
To consist of a Wooden box, case or Frame with a plate glass front, to contain a
series of Maps &c., (in a continuous form) encircling a roller at the top and another
at the bottom, both having a toothed metallic rack (one being at one end on the left
of said bottom roller and the other on the right of top roller. Which racks are set in
motion respectively, by an endless chain passing round pullies to the front-drawn
downwards: The one on the left will work the bottom roller, and, by passing under
it, draw the maps downwards; and the one on the right will work the top roller,
passing (over pullies) under it, draw the Maps upwards. By this system two hundred
or more feet of continuous Maps can be contained within the case, and form an
interesting reference, easy of access; suitable for Library, Hall, Lecture room &c.
whether on a chimney piece, Console Table, or hung on a Stand as a fire screen.
Dated this 19th day of August 1886.

page_text: I CHARLES HENRY COPE of Wigginton Park Tamworth, Staffordshiro, retirod
Civil Engineer and now of no occupation, 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:-
To consist of a Wooden box, case, desk or frame with a glazed front, to contain a
series of Maps &c in continuous form, nailed or otherwise secured to a pair of wooden
rollers hung in metallic contres as far distant from each other as the dimensions of
the frame will admit. A pair of these rollers may be hung horizontally, one at the
top and the other at the bottom for a series of Maps &c reading downwards, or may
be placed vertically for Maps &c. read horizontally. In all cases, whether horizontal
or vertical, each roller will have a metallic pulley wheel at each end, one wheel being
secured to the roller (which I term the fixed pulley), and the other free (called the
loose pulley); and their relative position when the rollers are hung or placed will be
contrariwise; for example, (in horizontal rollers) a fixed one on the right at top will
be placed over a loose one at the bottom, and a loose one on the loft at the top over a
fixed one at the bottom. Those pullies (about six inches in diameter) will be hung or
placed so as to project in front of the Frame and will be worked or set in motion by
an endless cord or chain passing round, and connecting them outside the frame in
front, and inside at the back: there will also be smaller pullies as hereinafter described.
The effect therefore will be, that by drawing down the right hand cord or chain the
Map &c. will be raised and by drawing down the left hand one the Map &c. will be
lowered. In the event of a cord being adopted the action is illustrated by Sections A
and D respectively: the Pulloy (a) being fixed, and (b) loose, the draught is
downwards, and in order to maintain the required tension of the cord it is drawn out
of the vertical line at the back by a small pulley (c) which is acted upon by a screw-
the head of which is seen on Elevation (at c c) The right hand cord movement is
illustrated by Section D, the cord being drawn under loose pulley (d), round tension
pulley (e), over small pulley (f), round fixed pulley (9), over small pulley (h), to (a):
which will draw the Map &c. upwards. I have introduced an alternative tension
adjustment (e) to be worked by a milled edged screw at the side (ee) in Elevation.
In the event of a chain being used the action on the left (Section B) would be the same

page_text: as for a Cord, excepting that the bottom (tight) pulley would be toothed; but the
action on the right will be somewhat different: the chain, after passing round the small
pulley (i in Section C), will take up and propel the toothed fixed pulley (5), and then
pass round the small pulley (k). In the case of a Map &c. being drawn from right to
left and left to right, the rollers will be placed vertically and the cords or chains
horizontally, at top and bottom; and worked to the right or to the left (as shown on
Sections A or B).
