IMPROVEMENTS IN WINDOW BLINDS
Year: 1884

page_text: I IMMANUEL CARL RUDOLPH LINDENZWEIG of Hammersmith in the County
of Middlesex, Coach Builder do hereby declare the nature of said Invention for
IMPROVEMENTS IN WINDOW BLINDS " to be as follows:-
According to this invention I construct window blinds without the usual tapes
which obstruct the view, are a hindrance in cleaning, and have to be frequently
replaced or repaired because of wearing out or of becoming detached or soiled. I
also do away with the cord holes through the laths whereby the latter are weakened.
I also do away with two out of the four pulleys. Instead of the tapes I use chains
which I arrange and attach in the following manner. At or near the inner and
at or near the outer end edge of each lath I provide a small pivot which I prefer
to fix in metallic shoes fastened on each end of each lath. These pivots are
connected by the link of the chains passing over or round them. The pulling
cord is passed through swivelled eyes or rings which are also attached to the said
shoes. In case of very wide blinds I also provide a single central chain which I
connect to a pin which is held by a small metallic shoe or bent plate fixed to the
centre of the edge of the lath either towards the room or towards the street.
The pulling cord is at each end fastened to the bottom lath. The left hand side
of the cord passes up through the aforesaid swivel rings and over a pulley then
across the top of the blind and over another pulley there, then down by the right
hand side of the blind to the length required for pulling up, then up and over the
right hand pulley and then down through the swivel rings to the bottom lath to
which its end is fixed.

page_text: I, IMMANUEL CARL RUDOLPIT LINDENZWEIG of Hammersmith in the County
of Middlesex Coach Builder do hereby declare the nature of said Invention for
"IMPROVEMENTS IN WINDOW BLINDS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-

According to this Invention I construct window blinds without the usual tapes
which obstruct the view, are a hindrance in cleaning and have to be frequently
replaced or repaired because of wearing out or of becoming detached or soiled. I
also do away with the cord holes through the laths whereby the latter are weakened,
I also do away with two out of the four pulleys. Instead of the tapes I use chains
which I arrange and attach in the following manner and as illustrated by the
accompanying drawings. Figure 1 is a front elevation partly in section Figure 2
is an end view and Figure 3 is a plan of so much of a Blind constructed according
to my invention as will be necessary to explain same. Figure 4 is a plan and
Figure 5 is an end view of the end of one of the laths.
At or near the inner edge a and at or near the outer end edge b of each lath
I provide a small pivote which I prefer to fix in metallic shoes & fastened on each
end of each lathe. These pivots c are connected by the links of the chains f
passing over or round them. The pulling cord g is passed through swivelled eyes
or rings & Figures and 5 which are also attached to the said shoes d. In case of
very wide blinds I also provide a single central-chain, which I connect to a pin
which is held by a small metallic shoe or bent plate fixed to the centre of the
edge of the lath either towards the inside a or room or towards the outside bor
street.
The pulling cord g is at each end g' fastened to the bottom lath e. The left
hand side of the cord g passes up through the aforesaid swivel rings hand over a
pulley then across the top of the blind i and over another pulley g' there, then
down by the right hand side of the blind to the length required for pulling up,
then up and over the right hand pulley g' and then down through the swivel
rings to the bottom lath e¹ to which its end as before stated is fixed at g¹.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be perforined 1 declare that what
I claim is
In window blinds the stringing of same by chains and pivots c in combination
with cord passing over pulleys g³, g' and through swivel rings h the laths being
strengthened or secured by shoes & the ends of cord being secured to bottom lath e¹
all substantially as herein before described with reference to the accompanying
drawings.
