COMPLETE SPECIFICATION.
Improvements in Screens or Blinds.
1, THEODOR DAVIDS, of Hanover, in the Empire of Germany, Manufacturer, 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 constructing screens or blinds of laths held together by
some elastic material and covered with cloth, and consists principally in a peculiar
method of covering the laths with cloth, as herein after described.
In order to make my invention more clear, I refer to the accompanying drawing,
which forms part of this specification, and in which similar letters denote similar
parts throughout the several views.
Figures 1, 2, and 3 represent a cross section of the blind, showing the way in which
the cloth covering is attached.
Figure 4 is a front elevation of a blind.
Figures 5, 6, 7, and 8, show various ways of attaching the cloth to the laths.
Referring to figure 1, s, and s¹, are the laths, having their one edge pointed, and
in their other edge, a groove, so that the pointed or sharp edge of the one lath, will
lie in the groove of the next, and so on.
The laths or slats are held together by thin elastics, or wires 9, passed through

in figure 1, where it is interlaced between them, so that one slat shows the
wood, whilst the next is covered with cloth; or as in Figure 2, where the cloth

is passed over two slats at a time, and then under one, and so on.
manner is that shown in figure 4, where long thin strips of stuff, are taken and
interlaced between the slats, the first strip as in figure 1, the second, however, as shown
in figure 3, so that the first strip will pass over slat No. 1 and under slat No. 2,
whilst the second will be passed under slat No. 1 and over slat No. 2, by which means
a chequered pattern, as shown in front elevation in figure 4, will be formed.
Besides interlacing the stuff covering, 1 can fix it to one or both sides of the slats
in the manner shown in figures 5 and 7. If I wish to cover one side only of the slat
with cloth, I cut a slit in each side edge of the slat as shown in figure 5 at t' t¹, and
the end of the cloth is tucked into the slit. When the slats are now placed together,
and held by their elastics or wires, the cloth covering will be stretched tight by
the pressure of the sharp side into the groove of the next slat. I can then place
the slats as shown in figure 6, one with its cloth side outwards and the next
reversed.
When it is desirous to cover both sides of the slat, it is only necessary to make a
slit t¹, in the one side edge of the same, as shown in figure 7, the cloth being passed round
the sharp edge, and both its edges tucked into one groove, the slats being in that case
held together in exactly the same manner as in every other case (figure 8).
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 :-
First: A screen or blind composed of slats or laths placed together, having the
sharp edge of the one lath or slat, lying in the grooved edge of the next, and attached
by wires, cords, or elastics, q, interlaced with a cloth covering, for the purpose,
substantially as described

page_text: Secondly-A screen or blind, composed of slats or laths, of the form specified, and
attached together, by means of cords, wires, or elastics, the slats or laths being wholly
or partially covered with cloth, fixed in slits in their edges, in the manner substantially
as described.
