PROVISIONAL SPECIFICATION.
An Improvement in Window Blinds.
JOSEPH FERRIMAN WATERS, 19, Lawrence Lane Cheapside, E.C. Ware-
houseman, do hereby declare the nature of this invention to be as follows :-
This invention consists of making cloth used for window blinds with thicker or
closer threads in the warp at each side of the cloth than those in the centre,
whereby the necessity & cost of hemming is dispensed with, & waste of cloth in
making the hems is avoided.
At the same time this improved hems possesses the appearance & utility of the
sewn hem as hitherto used.
This improvement also reduces the labour & cost of squaring & fixing the blinds
to the rollers, ensures greater accuracy in squaring, & more perfect hanging, &
rolling, of the blind.

An Improvement in Window Blinds.
I JOSEPH FERRIMAN WATERS of No. 19 Laurence Lane, London Ware-
houseman 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 :-
"
In making cloth window blinds as heretofore usual a piece of fabric is taken of
❝ hem
greater width than the window to which the blind is to be applied and a
is formed at each of the sides or edges of the said piece of fabric whereby it is
strengthened at the said parts its width being thereby reduced to that required for
the blind.
This invention consists in making cloth for window blinds so that the hemming
of the sides of the blinds is rendered unnecessary and so that both the appearance
and useful effect of hemming are produced in the said cloth.
According to the said invention the cloth is woven with thicker warp threads at
and near the sides of the piece than at the intermediate part or the warp threads
at and near the sides of the piece are set closer together than at the intermediate
part. By this means the cloth is sufficiently strengthened at and near its edges to
admit of its use for blinds without need for strengthening them by hemming as
heretofore usual consequently the fabric is not required to be of greater width than
the required width of the finished blind.
I have found in practice that a fabric strengthened at and near its edges
sufficiently to fit it for use as herein before described may be produced by placing
the warp threads about one third or one fourth closer at the parts to be strengthened
than at other parts or by using for the parts to be strengthened warp threads about
one third or one fourth thicker than those at other parts and in either case by
making the strengthened parts about one inch and a half wide. 1 however do not
confine myself to these proportions.

page_text: By the improvement hereinbefore described economy of fabric is effected and
the labour of squaring and hemming the blinds at the sides is avoided, and more
perfect rolling of the blinds is insured.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :
The improvement hereinbefore described in window blinds which consists in
strengthening the edges of the fabric from which the blinds are to be made by
using in the manufacture of the said fabric thicker warp threads for the portions
at and near the sides than for the intermediate portion or by placing the warp
threads closer at and near the sides than at the intermediate portion.
