COMPLETE SPECIFICATION.
Improvements in Window Blinds.
I, GEORG REISSIG, of 14, Ziegelstrasse, Chemnitz, in the Empire of Germany,
Merchant, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
-
The present invention consists of a slat blind composed of a series of vertical
strips, each having horizontally arranged slats, and being adjustable in vertical
planes and capable of being rolled up after the manner of an ordinary roller blind.
In addition to this the blind is provided with a device by means of which the
lower end of the same may be propped outwardly.
And in order to render the present specification more easily intelligible refer-
ence is had to the accompanying drawing in which similar letters of reference
denote similar parts throughout the several views:-
Fig. 1 is a front elevation of the blind,
Fig. 2 a similar elevation with the vertical strips differently adjusted,
Fig. 3 a perspective view with the blind partly rolled up and its lower end
adjusted outwardly,
Fig. 4 a part front elevation drawn to a larger scale;
Fig. 5 a transverse section of Fig. 4.
Fig. 6 a plan view of the roll for the strips,
Fig. 7a section on line M M Figure 4.
Fig. 8 a front elevation of a modified form of blind,
Fig. 9 a vertical cross section through Figure 8 and
Fig. 10 a horizontal section through the window showing the blind in plan
view.
Referring to Figures 1 to 7:-The blind is composed of a series of vertical
strips a, each formed of slats in the ordinary manner and pivoted at the centre of
its top and bottom bars to a top and bottom bar or roll b and c. The top roll b is
pivotally mounted in the window framing in any suitable manner and provided
at the right hand end with a roll d having a cord f by means of which the roller
may be turned and the strips a wound thereon. At the opposite end the roll 6 is
provided with a drum, having mounted thereon two guide pulleys h and i for a
cord. In the cord roll d a pulley g is also mounted, said three pulleys h, i and g
being arranged to rotate in a horizontal plane when the blind has been let right
down. At each side of the blind are suitably arranged in the window framing
guide rods n, n serving to guide the lower bar c of the blind. On the left hand
rod n, a weight 1, having roll m mounted therein, is arranged to slide loosely
up and down, said rod and may be fixed in any desired position thereon by means
of a screw o. A cord passes round said roll m, and leading upwards its two
lines are guided over the rolls h and i and then round the roll g, thus forming an
endless cord, the front or rear horizontal line of which is attached to one corner
of each of the vertical strips as will be clearly seen from Figure 2. By pulling
one side of this cord the strips a may be adjusted into any desired position
thus for instance, from the position shown at Figure 1 to that shown at Figure 2.

page_text: If then the cord is tightened and the weight clamped on the rod n by means of
the screw o, the strips will remain in the position to which they have been adjusted.
The strips a being composed of slats may easily be wound on the roll 6 by means
of the cord f after having been adjusted to lie in one plane. When the blind is
rolled up the clamping screw for the roll of cord k should be loosened and the latter
will wind on the roll at the left hand side of Fig. 4. As will be seen from Figure 3,
side rods p, p are swivelled to the lower bar e which may be turned onto the bar
and secured there in any suitable manner, or they may also be turned round at
right angles to said bar and be hooked into suitable eyes fixed in the window
frame and thus support the lower end of the blind outwardly.
As shown at Figures 8 to 10 the blind may also be arranged as an ordinary
slat blind, being provided with upper and lower bars q, q' and having the side
strips a somewhat narrower and connected to the cross-bars q, q', so as to form
a frame. This frame with the vertical strips a, a can be easily drawn up and let
down in any desired manner. The adjustment of the strips take place in the same
manner as heretofore described.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of a series of vertical strips formed of slats, an upper and
lower bar, a drum on said upper bar having mounted therein two guide pulleys
and a card roll at the opposite end, having mounted therein one pulley, means
for pivoting said strips centrally to said upper and lower bar, a cord, attached to
one upper corner of each of said strips, laterally arranged guide rods to the window
frame and a weighted roll on one of said rods round which said cord passes
substantially as described.
·
2. The combination of an upper and lower bar, a series of strips composed of
slats and centrally pivoted to said upper and lower bar, guide rolls on said upper
bar as specified and laterally mounted guide rods n, na weighted guide roll m to
slide on one of said rods n, a cord without end to pass over said guide rolls and
having one of its lines fixed to corresponding corners of all the strips, means for
rotating the top roller, and arms swivelled to the lower roller and means for
detachably securing their free ends to the window frame substantially as described.
3. The combination of an upper and lower bar, a series of vertical strips
centrally pivoted to said upper and lower bar, means for adjusting said strips in
the vertical plane, substantially as described and lateral narrow strips a¹ a¹ to
connect said upper and lower bar and means for actuating the blind up and down,
substantially as described.
4. Slat blind, substantially as described and shown in the drawings.
