Year: 1878

page_text: LETTERS PATENT to Charles Haarburger, of London Wall, in the City
of London, Manufacturer, for the Invention of "AN IMPROVED WINDOW
BLIND"
Scaled the 22nd November 1878, and dated the 20th June 1878.
PROVISIONAL SPECIFICATION left by the said Charles Haarburger at the
Office of the Commissioners of Patents on the 20th June 1878.
CHARLES HAARBURGER, of London Wall, in the City of London, Manufacturer.
"AN IMPROVED WINDOW BLIND."
This Invention relates to an improved window blind, the object being constructing
a blind from strips of wood, cane, or other material, or a combination of such like
strips, each being of the same body, or of different bodies, such as wood and cane
or of wood and metal, of any desired length or height, said strips being so jointed
or attached that they can be drawn asunder or opened out to fit any width of
window sash.
The Invention consists in arranging strips or lengths of wood, cane, or other
material, diagonally across one another, to forin a sort of latticework, and in
passing pins through the strips, where they cross each other, but in a loose manner,
that each pin forms a joint, upon which the strips may inove.
When sufficient of these strips are made up the parts to form the sides of the
blind are enclosed within vertical pieces, forming the rails for the attachment of the
blind to the window sash.
By this Invention a blind for a window, to take the place of a wire blind, is
made of open cross-barred strips, which can be opened out, and be thereby caused
to fit any size of sash, and which can be, when removed from the sash, contracted
and rolled up to occupy a small space, without being injured or destroyed.

page_text: The strips of material may be of any colour or combination of colours, and they
may all be of the same length, or of varying lengths, to form a wavy top edge to
produce ornamental effect.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Haarburger in the Great Seal Patent Office on the 18th
December 1878.

"AN IMPROVED WINDOW BLIND."
This Invention relates to an improved window blind, the object being constructing
a blind from strips of wood, cane, or other material, or a combination of such like
strips, each beiug of the same body, or of different bodies, such as wood and cano,
or, of wood and retal, of any desired length or height, said strips being so jointed
or attached that they can be drawn asunder or opened out to fit any width of
window sash or window frame.
The Invention consists in arranging strips or lengths of wood, cane, or other
material, diagonally across one another, to forin a sort of latticework, and in passing
pins through the strips where they cross each other, but in a loose manner, that
each pin forms a joint, upon which the strips may move.
When sufficient of these strips are made up the parts to form the sides of the
blind are enclosed within vortical pieces forming the rails for the attachment of the
blind to the window sash or window frame.
By this Invention a blind for a window is made of open crossed-barred strips,
which can be opened out, and be thereby caused to fit any size of sash or window
frame, and which can be, when removed from the sash, contracted and rolled up to
occupy a small space, without being injured or destroyed.
The strips of material may be of any colour, or combination of colours, and they
may all be of the same length, or of varying lengths, to form a wavy top edge to

page_text: to a window sash or to a window frame. These rails or bars are kept in place by
eye screws &, which pass through orifices ƒ contrived in the said rails and enter the
framo or sash of the window Z. These eye screws, seen in fragmentary view
Figure 1*, are in the position they would occupy when holding the blind in place,
but if it be desired to remove the blind from the window the eye or head of the
screw must be turned in such position that it will lie in the direction of the length
of the orifice; the blind can then be readily removed.
A strip or band of india-rubber or a coiled spring may be attached to each of the
side pieces c at their upper and lower ends, and serve to automatically close the
blind on its being removed from the window. These strips, bands, or coiled springs
at the same time form a top and bottom frame or rail for the blind; or wooden
strips, sliding one within the other, may be attached to the upper and lower
portions of the side pieces c, so that on the blind being opened or closed such strips
will slide outwards or inwards with the blind, and thus form a top and bottom rail
or frame for the same.
It will be readily seen that by my Invention I am enabled to provide a blind
which can be adapted to fit any size width of window.
Having now described the nature of the said Invention, and in what manner the
same may be performed, I declare that I claim, the improved window blind con-
structed and arranged substantially as horein described and shewn, whereby it can
be adapted to fit any width of window sash or window frame.
In witness whereof, I, the said Charles Haarburger, have hereunto set my hand
day of Decomber, in the year One thousand cight
and seal, this
hundred and seventy-eight.
