The Invention has for its object improvements in dwarf window blinds or screens,
and relates to that class of blinds or screens which are made of wood.
Blinds or screens of this character as produced hitherto have been made of one
piece of wood cut into fretwork in the usual way, and in consequence thereof
they have been costly to produce and liable to warp and twist out of shape.
Acording to my Invention I form the blind of a number of vertical slats or
laths arranged side by side. These slats or laths are first cut to the desired size,
and are then ornamented by means of a fret saw or otherwise.
A number of these slats or laths are then arranged side by side, and are securely
fixed by screws or otherwise to narrow strips of wood moulded or otherwise
ornamented, and placed along one or both sides of the blind, and preferably top
and bottom.
•
Blinds or screens made in this manner are both easy and inexpensive to produce
and will not warp or twist out of shape, their peculiar construction allowing of the
natural expansion and contraction of the wood.

"IMPROVE-
The Invention has for its object improvements in dwarf window blinds or screens,
and relates to that class of blinds or screens which are made of wood.
Blinds or screens of this character as produced hitherto have been made of one
piece of wood cut into fretwork in the usual way, and in consequence thereof they
have been costly to produce and liable to warp and twist out of shape. According
to my Invention I form the blind of a number of vertical slats or laths arranged
side by side.
These slats or laths are first cut to the desired size, and are then ornamented by
means of a fret saw or otherwise.
A number of these slats or laths are then arranged side by side and are securely
fixed by screws or otherwise to narrow strips of wood moulded or otherwise
ornamented, and placed along one or both sides of the blind, and preferably top
and bottom. Blinds or screens made in this manner are both easy and inexpensive
to produce and will not warp or twist out of shape, their peculiar construction
allowing of the natural expansion and contraction of the wood.
And in order that my said Invention may be more clearly understood and
readily carried into effect, I will proceed, aided by the accompanying Drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation, and Figure 2 is a cross section of a blind or screen
constructed according to my Invention.
a, a are a number of vertical slats or laths which are cut to the required size,
and ornamented in any desired manner by means of a fret saw or otherwise.
These slats or laths are arranged side by side, and are securely fixed in position by
screws or otherwise to narrow strips b of wood, moulded or otherwise shaped or
ornamented, and placed along one or both sides of the blind and preferably along
or near the top and bottom thereof.
Blinds or screens made as above described allow each separate lath or slat to
bend independently of the others when subjected to pressure, thus giving full play
to the natural elasticity of the material; they can also be shortened by cutting or
lengthened by adding other slats or laths thereto without in any degree destroying
or injuring the blind, whilst in case of accident the broken part can be replaced at
slight cost.
Having thus described the nature of my said Invention, and the mode in which
I carry the same into effect, I would have it understood that what I claim is the
manufacture of dwarf window blinds or screens by fixing a number of laths or
slats a to cross strips b of wood, substantially as herein shown and described.
In witness whereof, I, the said William Henry Dandy, have hereunto set my
hand and seal, this First day of October, in the year of our Lord One
thousand eight hundred and eighty one.
