page_text: I, MATTHEW THRAVES SHARP, of 15, Gladwell Road, Crouch End, in the County
of London, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in roller blinds, the improvements having
for object to so construct such blinds that they will admit of ventilation at the upper
part of the windows to which they are applied.
In carrying out my invention I form in the blind near the upper part thereof
an opening or openings which may or may not be covered with an open fabric or
network, the said opening or openings being so placed that when the blind is pulled
down to cover the window it or they will be opposite the top part of the window.
To the said opening or openings I adapt a flap or shade so arranged that if it be
required to cover the opening or openings it is merely necessary to pull the blind
down somewhat lower when the flap or shade will cover the said opening or
openings.
It will be obvious that I can adapt my ventilating arrangement to more than one
part of the blind.
I, MATTHEW THRAVES SHARP, of 15, Gladwell Road, Crouch End, in the County
of London, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

openings.
It will be obvious that I can adapt my ventilating arrangement to more than one
part of the blind.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:-
Figure 1 is a front elevation; and,
Figure 2 a section shewing my improved blind applied to a window, the blind being
in the position it occupies when the opening in the blind is uncovered; and,
Figures 3 and are respectively a back elevation and section shewing the blind
pulled fully down, the flap or shade being behind the said opening so as to cover
the same.
a is the blind which in the drawing is shewn applied to a window by the ordinary
spring roller b; c is the opening (or there may be more than one) in the upper part
of the blind, which said opening may if desired be covered with open fabric or net-
work such as d; e is the flap or shade which I apply to my blind, this flap being
deep enough to cover the opening; it may be permanently attached to the blind;
or may be detachably connected thereto. The flap is provided at its lower end with
lace or other ornamentation e¹ for holding it down and also advantageously with
springs, for bending its lower edge away from the opening c when it covers
the said opening as hereinafter described to allow of ventilation. The springs being
flexible can be rolled round the roller when the blind is rolled up.
By this arrangement when the blind is pulled down to the position shewn in
Figures 1 and 2 the flap c will be drawn over the roller & leaving the opening cun-
covered for ventilating purposes; if, however, it is required to cover the said opening
to exclude light, the blind is pulled further down, that is to say, into the position
shewn in Figures 3 and 4 so as to allow the flap e to fall behind the opening c, and
to cover the same, but still allowing of ventilation.
f is the usual cord for releasing the spring by which the blind is raised.
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:
1. A window blind having an opening (or openings) such as c, and a flap or shade
such as e, arranged and operating as, and for the purposes, described.
2. In a window blind of the kind described in Claim 1 providing the flap e with
a number of springs e, substantially as and for the purpose herein before described.
3. The manufacture and use of the improved blind herein before described and
illustrated in the accompanying drawing.
