"IMPROVEMENTS IN SCREENS FOR INDOOR AND OUT-DOOR USE."
The object of this Invention which relates to certain useful and efficient improve-
ments in screens for indoor and outdoor use, is to provide a simple and effective
means of obtaining protection from draughts, and of separating, dividing, or
screening off any object or part of a room (for example), and of being of general use
for all the purposes for which screens are required. When not required these
screens can be at once rolled up so as to occupy a comparatively small compass,
and be placed on one side.
tr
Our improved roll-screen will be found a very superior substitute for the
Spanish" or folding-screen, it is constructed of a series of narrow wooden laths or
slats, which are articulated or so shaped and connected, linked, or fastened together
at their edges as to have the capability of free motion in either direction, in order
to allow of the screen being readily placed in an angular, curved, or straight form
without any openings between the laths becoming visible. The laths may be made
of a plain, reeded, or of any desired shape or; cross section, and they are linked or
bound together by wires, bands, or springs of metal or other substance in such a
manner, that the fastenings are at all times invisible, being within or passed
edgewise and transversely through the laths.
If required the outermost or closing laths of the series may be provided with
tightening screws, by which the connections of the laths can be more or less
tightened up, according as the screen by alternate use in the open air and indoors
requires slackening or tightening up, the nuts of the tightening screws forming

page_text: projecting handles, which by means of fastenings attached thereto, may be utilized
for giving a firm position to the screen.
The outside of the screen may be varnished in imitation of any kind of wood,
and the inside may be lined with canvas, and painted or not, and may then be
coated with a, damp-proof preservative solution.
The improved screens will be found of special utility for the bed room of an
hotel or other large building or mansion, as they will protect the bed or other piece
of furniture, such as an easy chair or a sofa, against draught; as a remedy for the
inconvenience experienced in winter time by the cold air streaming into rooms; in
cases of limited accommodation, or of illness, when a bed or couch may be required
in a sitting room, the same may be enclosed without interfering with the usual
arrangements of the room; in pleasantly situated but draughty balconies or other
situations as a protection against wind; in nurseries as fire-screens, and for protection
against draughts; in dining rooms or restaurants and other places of public resort,
where some of the frequenters may desire privacy or to be screened off from others;
and in hospitals to keep some of the beds separate, and to guard the patients
against draughts. In the last case it is most advisable to use screens, both sides of
which have a smooth and washable surface, so as not to retain any contagious or
infectious matter or smell.

"IMPROVEMENTS IN SCREENS FOR INDOOR AND OUTDOOR USE."
The object of this Invention which relates to certain useful and efficient improve-
ments in screens for indoor and out-door use, is to provide a simple and effective
means of obtaining protection from draughts, and of separating, dividing, or
screening off any object or part of a room (for example), and of being of general
use for all the purposes for which screens are required; and when not required,
these screens can be at once rolled up so as to occupy a comparatively small
compass, and can be placed on one side.
Our improved roll screens are illustrated on the accompanying Sheet of
explanatory Drawings in two varieties of their construction, and in some of the
many forms to which they can be bent. They are constructed of a series of narrow
wood laths or slats, which are articulated or so shaped and connected, linked, or
fastened together at their edges, as to have the capability of free motion in either
direction, in order to allow of the screen being readily placed in an angular, curved,
or straight form, without any openings between the laths becoming visible.
Figure 1 represents an elevation of one of our improved roll-screens as thus
constructed; Figure 2 is a plan view thereof, showing the same bent to a curvilinear
formation in opposite directions, and Figure 3 represents an enlarged sectional plan
view of part of a screen as thus constructed, and illustrates one method of binding
together or uniting the wood laths of which the screen is composed, so as to allow
of facility of manipulation whilst preserving continuity of surface.
1 represents the wood laths, one edge of each of which is of a rounded or convex
formation, the other edge being of a corresponding hollowed or concave formation,
so that the contiguous edges of adjoining laths correspond with and fit each other,
which allows of the screen being turned into any desired shape, as represented in
Figure 2, without its continuity of surface being affected, or any openings becoming
apparent between the laths. 2 represents wires (of which there may be two or
more) by which the series of laths composing the screen are united or held together,
and both ends of which may be secured by screws 3 which are passed through the
closing or end slats, or if required, one of the outermost or closing laths of .the
series may be provided with tightening screws 4, by which the wires or con-
nections 2 of the laths can be more or less tightened up, according as the screen by
alternate use in the open air and indoors requires slackening or tightening up; tho
nuts 5 of the tightening screws being formed with ring shaped or other suitably
shaped terminations, so that by the intervention of any suitable fastening, they
may be utilized for giving a firm position to the screen. The wires are passed
transversely through the laths through holes made edgewise therein, and thus they
are at all times invisible.
The laths 1 may be made of a plain, reeded, or of any desired shape or cross
section, and they may be otherwise linked or bound together by wires, bands, or
springs of metal or other substance than as herein before described. The necessary
connection may be formed by a strong inside lining 2 of canvas, as shown in the
enlarged plan view. Figure 4, a front view of a screen thus constructed is shewn
in Figure 5, and a plan view, as bent in Figure 6.
The outside or both sides of the screen may be varnished, or may be grained and
varnished in imitation of any kind of wood, or be otherwise ornamented, and the
lined inside may be painted or not, and may then be coated with a damp proof
preservative solution.

The improved roll screens will be found to be a very superior substitute for the
Spanish" or folding screen, and of special utility for the bed room of an hotel or
other large building or mansion, as they will protect the bed or other piece of
furniture, such as an easy chair or a sofa, against draught; as a remedy for the
inconvenience experienced in winter time by the cold air streaming into rooms; in
cases of limited accommodation, or of illness, when a bed or couch may be required
in a sitting room, the same may be enclosed without interfering with the usual
arrangements of the room; in pleasantly situated but draughty balconies or other
situations as a protection against wind; in nurseries as fire-screens; and for protection
against draughts; in dining rooms or restaurants and other places of public resort,
where some of the frequenters may desire privacy or to be screened off from others;
and in hospitals to keep some of the beds separate, and to guard the patients against
draughts. In the last caso it is most desirable to use screens, both sides of which
have a smooth and washable surface, so as not to retain any contagious or infectious
matter or smell.
The advantages of screens constructed according to our Invention are, that the
protection from draught, even when on the ground will be complete; the handling
of the screen is very convenient; the useful applications of the screen are very
numerous, as they are preserved against the action of damp, and can therefore be
used as well in the open air as in the house; they can be placed in any desired
curved or angular form; they occupy a comparatively very small space when rolled
up, and their construction is very solid, and admits of any accidental damage being
easily repaired.
Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, we would remark in conclusion that what we claim as the Invention secured
to us by the heroinbefore in part recited Letters Patent is,-
First. The improved manufacture of screens suitable for indoor and outdoor use,
by so articulating or laterally connecting a series of wood laths or slats, as that they
will have such freedom of movement as will allow of their being readily placed in
any such desired curved, angular, or straight form, as suitable to effect the required
purpose without any through openings between the laths becoming visible, the
laths being if required protected from the detrimental influence of moisture or
dampness, by varnishing, painting, or otherwise coating them with any suitablo
preservative composition, substantially as hereinbefore described and as illustrated
on the accompanying Sheet of Drawings.
Second. The combination with screens as thus constructed of tightening screws,
or of other equivalent means, by which the connections of the laths may be more or
less tightened up, substantially as hereinbefore described and as illustrated on the
accompanying Sheet of Drawings.
In witness whereof, we, the said Theodor Davids and Carl Weiss, have
hereunto set our hands and seals, this Eighth day of April, in the year of
our Lord One thousand eight hundred and eighty one.
TH. DAVIDS.
