TRUVIDIONAL DEECIFICATION.
Improvements in or relating to the Covering of Maps, Pictures,
and the like.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, London,
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a com-
munication to me from abroad by Edwin L. Kirtland and Lewis Edward Bellows
both of Holyoke, Massachusetts, U.S.A. Gentlemen,) to be as follows:
--
This my invention relates to wall maps, pictures and the like, and it has for its
object to provide them with a curtain or covering which can be readily lifted or
removed when desired.
The invention consists in the provision of a curtain or covering of preferably the
same width and length of the map and having wooden or other stiffening pieces at
its two ends. The end or ends of one or more cords are secured to the upper
stiffening piece of the covering and the remaining end or ends after having been
passed over suitable pulleys or other suitable guiding means secured to a piece of
wood or the like attached to the wall above the map, are attached to the upper
stiffening-piece of the map.
When it is desired to uncover the map, picture or the like, it is pulled down-
wards, and the covering is correspondingly raised, and when it is desired to cover
the map, picture or the like, the covering is pulled downwards and the map, picture
or the like is correspondingly raised.
Dated this 9th day of April 1890.
COMPLETE SPECIFICATION.
Improvements in or relating to the Covering of Maps, Pictures,
and the like.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, London.
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a com-
munication to me from abroad, by Edwin L. Kirtland and Lewis Edward Bellows,
both of Holyoke, Massachusetts, United States of America, Gentlemen), 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 combined map and a curtain for protecting and concealing
the map, the object of the invention being to provide in curtained maps means whereby,
on desiring to expose the face or any part of the face of the map by moving the map
a given distance, the curtain therefor will be withdrawn and caused to uncover an area
having a width greater than the length of movement of the map; and the invention
consists in the construction and combination of the map, the curtain, and supporting
and connecting means for and between the said map and curtain, all substantially as
will hereinafter more fully appear and be set forth in the clains, reference being
particularly had to the accompanying drawings, forming part of this specification, in
which the curtained map and the manner of its operation are illustrated.
Figure 1 is a perspective view of the curtained map properly suspended, with the
curtain thereof shown as covering the map-face.
Figure 2 is a similar perspective view to Figure 1, but showing the relative positions
of the parts when they are moved to uncover the entire face of the map, and
Figure 3 is a sectional and perspective view of the map on a somewhat larger scale
than the preceding figures to more clearly illustrate the arrangement and operation of
Price 8d

page_text: line 3 3, Figure 2.
Figure 4 is a vertical sectional view of a modification hereinafter referred to,
and
Figure 5 is a perspective view of a further modification also to be hereinafter
referred to, and
Figures 6 and 7 are vertical sectional views of the curtain and map and intervening
moveable connections shown in Figure 5, said parts being in different positions in the
different views.
As particularly shown in Figures 1, 2, and 3, the map A, consisting of a rectangular
or otherwise suitably formed sheet, at its top is provided with a horizontal strengthening,
stiffening, and carrying-strip a, of wood or other proper material, and is preferably
also provided at its bottom with a similar strip b, said strips being firmly secured to
the map-sheet in any approved manner.
The curtain B, of suitable flexible material for covering the map and having an
area corresponding thereto, is by its upper edge joined to said top carrying-strip a for
the map, being also preferably provided with a strip d at its lower edge, and horizon-
tally across its middle another strip f is secured to the curtain.
Above the top of the map on any suitable support-as, for instance, the bar D-is
fixed a pair of cord-guiding devices, as rollers 9 g, and to the top strip a of the map
cords m m are secured, thence passing over and around said rollers and carried and
connected to the said horizontal strip intermediately traversing the curtain.
With the map and curtain parts in such disposition that the curtain covers the
entire face of the map as seen in Figure 1, on drawing downwardly on the map a
given distance a map area will be exposed having a width double that of the down-
ward movement of the map, for, as will be clearly understood, on the downward
movement of the map the cord running from its top to the intermediate portion of the
curtain draws the latter upwardly as fast and as far as the map is drawn downwardly,
and when the map has been drawn down so far that its top is depressed to the place
formerly occupied by its middle the part of the curtain which formerly laid over such
middle is carried so far above the top of the map that the bottom of the curtain is on
the line with the top of the map, the entire face being uncovered. To cover the face
of the map by drawing downwardly on the curtain, the map moves upwardly and
the curtain downwardly, or when the map and curtain are of equal weight the map
may he covered by pressing upwardly on the bottom roll thereof.
In the drawings, two cords m m and rollers therefor on the bar D are shown,
such number being deemed requisite for practical and entirely satisfactory results,
although the employment of but a single cord connected to the top of the map and the
middle of the curtain in the vertical median line thereof, will insure operative results
in a degree, and of course for exceedingly large maps a greater number of cords and
guiding devices therefor may be employed.
In Figure 4 is shown a modification of the curtained map in which the curtain is
not directly attached to the map, but showing the laiter suspended by its top from one
end of the cord, which is thence passed over the roller and to the returned end thereof
the curtain by its top is attached. On drawing on the map as the same moves down
the curtain correspondingly moves up, and vice versa, accomplishing the same result
as under the construction hereinbefore described.
In Figures 5, 6, and 7 a further modification is illustrated, the same being an
arrangement of the map, the curtain therefor, and a support common to both thereof,
whereby substantially the same result is accomplished, and the curtain is shown as
adapted to be wound upon the roller in one direction to be raised and to unwind
therefrom to be lowered, the end of the curtain being secured to the roller.
The map is provided with flexible connections or cords passed above the same and
also wound around the said roller, (on the ends thereof which project outside of and
beyond the curtain) but in the reverse direction to the winding of said curtain, so
that on a turning of the roller in one direction, as by drawing on the map, the curtain
will be drawn up and wound around said roller, and the supporting-cords for the

page_text: map at the same time will be unwound from the roller and the map will be lowered,
and on causing the roll to turn in the opposite direction, as may be done by drawing
downwardly on the curtain as the curtain is unwound from the roll and lowered, the
map-supporting cords will be rewound and the map raised and disposed behind the
curtain.

While in the specification the curtain and connecting and supporting devices
therefor have been particularly mentioned, for the purpose of brevity, in connection
with a "map," of course it will be understood that it may as well be employed for
sheets or tablets bearing pictures, charts, or other configurations or matter.
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. In combination, a map and a curtain for covering the same, and a suitably
supported and guided moveable connection between and attached to both the map
and the curtain, whereby on moving the map through said connection the curtain
will be also moved, and vice versa, for the purpose set forth.
2. A map and a curtain therefor, attached to the upper portion thereof, and a cord
attached to the map by its intermediate portion passed over suitable guiding means,
and connected to said curtain below its top, for the purpose described.
3. The combination, with the bar D, having rollers, of the map or picture bearing
sheet having the top strip a, and a curtain for covering same, connected to said top
strip and having midway thereof the horizontal strip f, and the cords m m, connected
to said top strip of the map, thence passed over said rollers to and connected with the
said middle strip of the curtain, substantially as and for the purpose described.
