Improvements in Blinds for Windows or similar use.
I, CHARLES HUELSER of the firm of Huelser & Co. 142 Fleet Street, London
Solicitors of Patents do hereby declare the nature of this invention, a communication
to me from abroad by Johannes Paul Ortmann of Zittau in the Kingdom of Saxony,
Empire of Germany, to be as follows:-
The object of this invention is an improved blind, the fabric of which consists of
a suitable number of vertical strips, capable of axial displacement, and can be rolled
up as usual, when said strips are made to form one plane.
To attain this end the improved blind is essentially constructed as follows:
Each of the strips of fabric referred to is secured at the top and likewise at the
bottom to a horizontally revoluble bar, the bottom bars being connected with the
stretching rod, while the top bars are revolubly secured to and jointly form the lower
half of the roller. Each of the top parts is connected hinge fashion to a common
horizontal rod for the purpose of causing any axial movement given to one of the
bars to be imparted to the rest, said rod forming part of the roller, when the planes
of the strips coincide and the blind is capable of being pulled up.
To allow the strips to be operated, a vertically revoluble pin passing centrally
through the middle or any other top bar and through the upper half of the roller,
extends into a recess provided at the top of the latter. The upper extremity of said
pin has a polygonal cross section and fits into a corresponding key adapted to be
sunk into the recess or keeper referred to. This key is provided with a horizontal
cord pulley, capable of right or left revolution about a stationary guide bolt by
means of two cords placed into its groove. Another cord secured to the upper
elongated nave of the pulley serves for raising and lowering the latter i.e. for
engaging or disengaging the polygonal top of the pin mentioned above.
It is obvious from the foregoing description that by lowering and operating, by
means of the cords when the blind is let down, the pulley or key, the strips of
fabric forming the main part of the blind can be given an inclined position to either
side, and return to their normal position, to allow the blind, after the roller is released
from the key, to be pulled up in the usual manner.

Improvements in Blinds for Windows or similar use.
I, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers, London,
International Patent Agency, do hereby declare the nature of this invention, a
communication to me from abroad by Johannes Paul Ortmann of Zittau, in the
Kingdom of Saxony, Empire of Germany, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to blinds for windows and other use and has for its purpose
to provide a blind, the single strips of which can be given an inclined position and
also rolled up as shewn in principle in Figs. 1 to 6 of the accompanying drawing.
Figs. 7 to 22 represent supplements to the arrangements shewn by Figs. 1- to 6.
The latter is merely so disposed that only from the roller the displacement of the
movable blind strips is possible, while the supplements referred to embody devices

rolled up laterally and also to be used as a wood roller blind and to be adjusted in

Each
The improved blind consists in the main of linen or cloth-strips a secured with
their upper ends to revoluble roller portions 6 and with their bottom ends by likewise
revoluble staves c to the weight bar d. The portions b form the lower part, therefore
a half of the roller e and are jointly connected to a rod f, which serves to cause all
pieces to participate in the movement or displacement of one of the same.
of these pieces b is, revoluble about g, connected with the roller e. Through the
median roller portion & passes a pin h Figs. 4 and 5, which is formed into a square at its
upper end projecting within the roller e. Said square corresponds to a key k provided
with a cord pulley i. The latter has two cords and m, by means of which the said
key can be moved in different directions of revolution. A third cord n secured to
the upper elongated nave of the disc i, serves for raising or lowering the key k.
When the blind occupies the position shewn in Fig. 1 and the strips a are to be
given an inclined position in a given direction, a pull at cord or m suffices to turn
the cord pulley i in the desired sense. Thereby the key k is likewise turned and the median
portion b connected with pin his given a partial revolution. Consequently all
pieces of the blind are given an inclined position by their being joined hinge-
fashion by rodf. The strips a assume the position shewn in Fig. 6.
If the blind is to be rolled up, the strips a are given a parallel position to the
roller e by pulling the respective cord 1 or m, and the key k is raised by a pull at
cord n, whereby the key is disengaged from the square on pin Fig. 5. Conse-
quently the roller e is freed from the key and turns when the cord o is pulled and
the blind thereby rolled up.
In the supplements or extensions represented by Figs. 7 to 22, the blinds consists,
the same as with that shewn in Figs. 1 to 6, of single adjustable strips, which however
are so far modified as the carrying bar or rail d is attached to the lower part of the
blind as shewn in Figs. 7 to 10 and has the portions e revolubly secured thereon.
One of these turning pieces c¹ is fixed on a shaft n, which serves as a guiding and to
ensure at the same time a uniform movement of the upper and lower pieces b and c.
The shaft n is turned at t by means of hand wheel R, whereby the one lower piece c¹,
and through rail falso the rest of the lower turning pieces, are displaced. At the
upper end of the shaft n is provided a crank-like piece, which is formed into a

page_text: semicircular fork u, adapted to seize the upper piece b¹ which is secured to the
roller. As soon as the blind is let down and the shaft n turned, a displacement of
the upper turning pieces 6 takes place simultaneously with the lower portions c_by
means of fork u, and all strips of the blind can be given a suitable position. The
portions at the roller are likewise connected with each other by a rail f. The
stationary but revoluble shaft n may also be replaced as shewn in Figs. 11 to 13 by
an oscillating adjusting shaft n'. The latter is mounted on the crank-like piece g
provided in the bottom part of the window, while with its upper elastically movable
end it engages in the notch wo of the first turning portion of the roller and is
guided by the turning arm q' in the saine curve which n¹ is made to describe by q.
As soon as the swinging shaft is moved by q, the upper and lower portions b and c
move simultaneously. To roll up the blind, the elastic end of the shaft n¹ is removed
from notch w, the shaft itself given median position as is required for rolling up the
strips of the blind. Subsequently the blind is rolled up by cord o.
For the purpose
of allowing the blind, .e. the single strips a, to be displaced, a pulley device
and a shaft y are provided in the bottom portion of the window, by means of which
parts, in conjunction with shaft n', the lower turning portions c can be uniformly
adjusted with the upper pieces connected to the roller. Figs. 16 to 19 sheet II
illustrate a modification, in which the blind can be rolled up in horizontal direction,
the roller being vertical, whereas the turning of the blind strips is effected in the
manner above referred to, that is to say about the vertical axis of revolution of the
single fields or strips of the blind.
i¹
To allow of the said modification, the strips a are guided at top and bottom in
grooves z and consequently can be rolled on roller W or W. The guide grooves z
are provided in turning pieces b and c, which are stationary, but can be singly turned
about pivots g. The middle or any other turning portion b' or c¹ is secured at top
and bottom on a pivot g' carrying a pulley . By turning the latter by means of
cord x, also the two pivots g₁ are turned and consequently the pieces 61 h and c¹ c,
and the strips a are turned Fig. 19. The pulling bands or laces s serving to
conduct the blind strips to the roller W or W' must be so placed as not to form an
obstacle for the turning movement of the strips a, Figs. 17 to 19. The strips are
flexible and somewhat stiffened by a likewise flexible frame, and are connected with
each other by means of slide f.
In the modification shewn by Figs. 20 to 22, the adjustable blind can be combined
with an ordinary roller blind. The wooden or iron roller blind L is provided with
adjustable fields a which however are not secured direct to the roller but are placed
in the middle of the whole roller blind either at any suitable place over the whole
width or merely on part of the height of the blind corresponding to local requirements.
The arrangement is as follows:
Below the lowermost staff p in the upper adjustable turning piece 6 of every
movable roller blind field, a rail f is provided. The staff p carries pivots g which
are connected with the turning pieces b, i.e. with the adjustable blind portions a.
An equal arrangement is provided between the lower portion of the revoluble blind
portion a and the further undivided roller blind staffs. The fields a of the roller
blind are stiffened in some degree by connection of the single wooden staffs with each
other. Thus merely the upper turning pieces 6 need be moved in order to displace
the whole of the fields of the roller blind. This displacement is effected by the
turning movement of the pulley and is transmitted by means of rail fand crank c¹
to the roller blind fields a. The rail is so arranged that it can be commodiously
rolled up at the normal or closing position of the roller blind fields a and lays itself,
when the blind is being let down, with its eye into the pivot of the pulley crank e¹.
The latter as also the adjusting contrivance in general may he given various shapes
corresponding to particular requirements. By the aforedescribed modifications
Figs. 7 to 22, the arrangement shewn by Figs. 1 to 6 is rendered applicable in
different manners and attains a perfection by which it is made capable of being
employed for divers purposes.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1.) An adjustable window blind, characterised by the application of a divided blind
roller, whose lower longitudinal half consists of the revoluble single pieces b b
carrying the cloth strips a and capable of being given any suitable inclined position
to the roller half e, on the cord 1 or m being pulled, by means of a loose key k,
adapted to influence the median piece 61, and a connecting rod f, the key k being
capable of being raised by a cord n, whereby the single pieces bb, returned to their
original position, supplement the longitudinal part e to a blind roller actuated by
cord o, substantially as set forth.
2.) The blind referred to in claim 1, and made of any suitable material, so con-
structed as to be adjustable uniformly from below, for which purpose the bottom
rails and turning pieces c c are provided, which parts are operated by means of
shaft nor n', the latter serving as guide rods and transmitting the turning movement
to the turning pieces 661 of the roller W, whereby a uniform displacement of the
blind fields is attained, substantially as set forth.
3.) In the blind forming the subject of claims 1 and 2, the arrangement for
allowing the blind fields or strips to be rolled up laterally, for which purpose the
roller is separated from the turning pieces 661 and c c¹, the latter being provided
stationary in the upper and lower portion of the window, and having grooves
which serve for guiding the blind fields a connected by bands s to the roller W,
substantially as set forth.
4.) In the window blind forming the subject of claims 1 and 2 the modification,
that the adjustable fields a are lodged revolubly movable within a roller blind and
adapted to be moved by rail f about pivots g, substantially as illustrated and
described.
