LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director. of The
Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. "A. NEW OR IMPROVED WINDOW BLIND" A communication
to me from abroad by Hans Olausen, a person resident at Christiania in the
Kingdom of Norway
This invention relates to improvements in window blinds made of paper, linen,
.or other like material and differ from the ordinary blinds now in use by being so
constructed as to fold the paper or linen in plaits when drawn up and present an
appearance somewhat similar to the blinds known as Venetian blinds and which
are usually made of wood or metal
:
In order to form the necessary regularity and permanency of the plaits the
material is previously passed through a plaiting machine constructed especially for
the purpose.
The consistency of the linen used for the manufacture of these blinds is increased
by a coating of paint, varnish or other suitable means may if desired be employed
for that purpose
.
When manufacturing the blinds of paper it is advisable not to employ paper
containing any wood pulp
:
The manner of fitting the blind to the window and working is as follows..
The top fold or plait of the blind is fastened to a rod or. bar which rod or bar: is
supported in bearings or brackets fixed one on each side of the window frame
parallel one to the other

page_text: The bottom plait or fold of the blind is glued or fastened to a suitable rod or
lath of material sufficiently heavy to drawn down the blind at the loosening of the
cords which cords pass through holes in each fold or lath of the blind said holes
being protected by metal eyelets which also serve for the more smooth running of
the cords
The pulling up or letting down of the blind is facilitated by leading the cords
through rings or sheaves attached to the upper part of the window frame and rings
or sheaves may when preferred be secured to the top rod or bar of the blind by
which means the working of the said blind and cords thereof will be further
facilitated.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Lorentz Albert Groth in the Great Seal Patent Office on the
20th June 1883.
LORENTZ ALBERT GROTH, K.G.V., Civil Engineer and Managing Director of the
Universal Inventors' and Patentees' Financial Company, Limited, 30, Finsbury 1
Pavement, London, E.C., "A NEW OR IMPROVED WINDOW BLIND," a communication
to me from abroad by Hans Olausen, a person resident at Christiania, in the
kingdom of, Norway,
This invention relates to a new kind of window blinds, which resemble Venetian
blinds, but are much cheaper and lighter than the same.
The new blind consists chiefly of a sheet or sheets of canvas, paper, or other thin
and flexible material provided with folds and, attached at each end (top and
bottom) to a bar or rail of wood, iron or other stiff 'material, the lower bar being
sufficiently heavy to open or unfold the blind by reason of its own weight when
the blind is suspended at the top, and left to itself. For opening or closing the
blind, each panel formed by the successive folds is provided with two holes, one on
the right and one on the left side, through which pass two strings attached at one
end to the bottom bar and running: through all the panels up to the top bar, from
where they are led downwards along one side or 'both sides of the window, so as to
terminate at a convenient height above the floor, where they may be fixed like the
strings of ordinary window blinds.
The top bar is attached to the window casing in any suitable manner, and is,
provided with rings or loops, which serve for guiding the strings.
The accompanying drawings illustrate a window blind embodying this invention,
Fig 1 showing the blind extended at full length, while Fig 2 shows the same
partly drawn up."

a, a, a, are successive panels of the blind, b is the top bar, b' the bottom
bar; d and d are, the strings attached to the bottom bar and passing up
through the apertures e, e¹ of the panels and through the rings f,, to the side of.
the window, where they are guided downward through a fixed eyelet or over, a

page_text: roller, being of sufficient length to come within easy reach of the person who
draws up the blind.
Having now described the nature of the invention, and the best method, known
to me, of carrying the same into practice, I wish it to be understood that I do
not limit myself to the exact details shown by the drawings, but what I claim, is:
1. Window blinds made from folded paper, canvas or other thin flexible
material.
2. The means for drawing up the blind, consisting of strings passing through
apertures in the successive panels of the blind, and the rings attached
to the top-bar, substantially as described.
In witness whereof I, the said Lorentz Albert Groth, have hereunto set my
hand and seal this 19th day of June A.D. 1883.
