PROVISIONAL SPECIFICATION.
Improvements in Window Blinds.
I, KARL ALBERT FROSELL, of Smyrna, in the Ottoman Empire, but at present
of No. 4, Sinclair Road, West Kensington, in the County of Middlesex, Merchant,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in window blinds, and relates more
particularly to those known as Venetians. Instead of making the blind of laths,
I use a length of paper or other suitable material and crease or pleat it trans-
versely, the width between the creases being about the width of the ordinary lath.
As the cords are pulled the pleats are drawn together.
The present or any convenient cord gear is applied in the usual way.
The blind may be made in two or more portions, each one of which is fitted with
its special cord gear, the gear for any lower portion controlling the one above.

COMPLETE SPECIFICATION.
Improvements in Window Blinds.
I, KARL ALBERT FROSELL, of Smyrna, in the Ottoman Empire, but at present
of No. 4, Sinclair Road, West Kensington, in the County of Middlesex, Merchant;
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in window blinds, and relates more
particularly to those known as Venetians.
Iustead of making a Venetian blind as heretofore of laths or slats, I make it
continuous, i.e., the whole blind, or, in the case of a "top light" Venetian, as much
of it as is to be worked independently of the other portion, is not made of laths or
slats, but of one sheet or length of material, and this is the sense in which the word
"continuous is used throughout this Specification.
"
I use a proper length of paper or other suitable material, such as paper backed
with linen or canvas, stiffened woven fabric, or the like. I prefer to use paper
because of its low price. The length of material for any given window may be
stated (speaking generally) as rather less than the width of one of the well known
slats or laths multiplied by their number. The length of material is then creased
transversely from opposite sides alternately, so producing a corresponding number
of bands. The distance between the creases, or the widths of the bands, are
uniform, and are about the same or rather less than in the case of the well known
slats or laths.
The blind may be made in more portions than one. For example, the upper
portion of the blind may be made separate and distinct from the lower, for the
purpose of providing for the admission of light into a room without it being
necessary to pull the blind up from the bottom.
As the cords of my improved blind are pulled, the bands are gathered together.
A blind made according to the present invention is corded and taped in the well
known or in any other convenient way.
In order that my invention and the means by which it is to be carried into
practical effect may be thoroughly understood, I will now describe it and them in

page_text: detail, referring in so doing to the accompanying drawings which are to be taken as
part of this Specification and read therewith:
Fig. 1 is an elevation of a Venetian blind made according to my invention, and
shewn as down before the window.
Fig. 2 is a side elevation corresponding therewith.

Fig. 3 is a front elevation illustrating the present invention made up as a two
.portion or top light "blind. The upper portion is shewn as up' "and the lower
portion as "down."
Fig. 4 is a side elevation corresponding therewith.
a is the head of the blind. b, bare the parallel bands produced by the formation
across it of parallel creases c, c. It will be noted that all the bands are of the
same width, and that the creases are made alternately from opposite sides. The
creases are so made in order that the bands may be "gathered" together by the
shortening of the suspension portions of the cords. d, d are the tapes. They may
be used on one or both sides of the blind, but not necessarily on both sides, for, as
the blind is a continuous length, ladder tapes are not required.
The tapes d, d and the blind are made fast to each other by connecting the
former to the creases of the latter when it is extended. For effecting such
connection, any suitable device may be made use of, such as sewing, binding staples
or their equivalent. e is the bottom or foot lath of the blind. (Figs. 1 and 2)
are the cords for pulling the blind up or for letting it down. They are shewn as
provided in duplicate, for my improved blind can be worked from both sides,
because no cords are required for turning the bands upon their axes, i.e., for
66
opening" or closing the blind. g (Figs. 3 and 4) is the cord for raising or
lowering the top light," and h that for the whole blind. The "top light" tapes
are preferably behind that part of the blind.

The invention does not confine me to any particular method of cording and taping
blinds made according to it.
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. A continuous window blind divided into bands by parallel transverse creases,
as set forth.
2. The combination of continuous window blind divided into bands by parallel
transverse creases from alternately opposite side with tapes made fast to the said
creases, as set forth.
3. The general construction of window blind as set forth.
