Improvements in or appertaining to Venetian Blinds.
I, MARY PROCTOR, of 17, Hamilton Square, Birkenhead, in the County of Chester,
do hereby declare the nature of this invention to be as follows:-
This invention relates to louvre shutters or blinds, commonly known as venetian
blinds, made of slats or laths with spaces between them to admit light or air,
these slats being suspended on tapes to change the position of the slats, so as to
admit more or less light or air. These tapes have hitherto been nailed or other-
wise permanently fixed at the top, thus rendering it a more or less difficult matter
to remove the blind for cleaning purposes and for repair.
Now my invention has for its object to provide means whereby the tapes can be
easily detached when required and replaced, so as to render it easy for a domestio
servant to take down the blind without having to call in skilled assistance.
In carrying my invention into effect, the plan I prefer is to fasten the ends of
the tapes at the bottom in the usual manner, but at the top they are hooked on
to the top rail or lath or other suitable part of the blind. This may be effected
by providing eyes at the ends of the tapes and fastening hooks on the top lath on
to which the eyes are hooked so that they cannot slip off accidentally. The eyes,
however, can be very easily released from the hooks when required. A convenient
way of forming the hooks is by fastening plates to the top fath, in which plates,
three sides of rectangles are out and the tongue thus formed bent to produce a
spring tongue.
In thus describing my invention, however, I wish it to be understood that I do
not confine my invention to hooks, as the tapes can be buttoned or otherwise
detachably fastened in place instead of being hooked.

statement:

This invention relates to louvre shuttors or blinds, commonly known as venetian
blinds, made of slats or laths with spaces between them to admit light or air,
these slats being suspended on tapes to change the position of the slats, so as to
admit more or less light or air. These tapes have hitherto been nailed or other-
wise permanently fixed at the top, thus rendering it a more or less difficult matter
to remove the blind for cleaning purposes and for repair.
Now my invention has for its object to provide means whereby the tapes can be
casily detached when required and replaced, so as to render easy for a domestic
servant to take down the blind without having to call in skilled assistance.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Figure is one half a side view and one half a vertical section of my blind,
the slats however being removed;
Figure 2, a plan of the plate F.
Referring to these figures, A are the vertical tapes with cross tapes on which
the slats rest, C the lath or top rail to which the tapes A have hitherto been
nailed or otherwise permanently fixed. By my invention however I fasten the
ends of the tapes A at the bottom in the usual manner, but at the top they are
hooked onto the top rail or lath C instead of being nailed. This is effected by
providing eyes D at the ends of the tapes, and fastening hooks E on the top of
the top lath C, on to which the eyes are hooked so that they cannot slip off
accidentally. The eyes D however can be very easily released from the hooks
when required. A convenient way of forming the hooks E is by fastening
plates F to the top side of the top lath C, in which plates three sides of rectangles
are cut, and the tongues thus formed bent to produce spring tongues or hooks E.
Gare holes for fastening the plates to the lath C. A convenient way of forming
the eyes is shown in the figures. The tapes are folded at the ends, and the ends
of the wires which form the eyes D) are thrust through the tapes where they are
folded, and then bent at the ends into loops d to prevent the wires being removed.
As a further security, however, another wire is passed transversely through the
loops d on one face of the tape A, then bent at d³ and passed back on the other
side of the tape between it and the wire D, thus firmly securing the tape to the
loop. To prevent this transverse wire being accidentally removed, the wires at
the ends are finally slightly bent as shown. It is obvious however that this is
not the only method of fastening the loops to the tapes as safety pins or other
devices might be employed.
In thus describing my invention however, I wish it to be understood that I do
not confine my invention to hooks, as the tapes can be buttoned or otherwise
adjustably fastened in place instead of being hooked.
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
olaim is:-
1. The improvement in venetian blinds, which consists in hooking or otherwise
coupling the tapes at the top to the top rail or lath instead of nailing them as hitherto,
whereby the tapes can easily be detached when required or replaced, thus rendering
it easy for a domestic servant to take down the blind without having to call in
skilled assistance, substantially as described.
2. In venetian blinds coupling the tapes which support the slats to the top 5
lath or rail by means of spring-hooks und eyes, in such a manner that the tapes
can be easily detached when required and enable the blind to be more easily
removed for cleaning purposes or repair, substantially as set forth.
3. In venetian blinds in which the tapes can easily be detached from the top
Jath or replaced providing the latter with plates in which three sides of rectangles 5

substantially as and for the purposo described.
4. The general arrangement of parts taken as a whole substantially as set
forth.
