I, JOHN WILLIAM HULL, of 39 & 40, Bartholomew Close, in the City of London,
Window Blind 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:
The object of this my invention is to provide blinds for the windows of houses
and shops and other buildings and places that shall exhibit the great excellence
and afford the great advantage of having very considerable fire-resisting properties
and qualities while at the same time they shall be cheap and extremely convenient
for use and simple in operation.
To carry out this object I take a piece of wire gauze of any desired mesh and
of any appropriate stoutness and strength and of the required dimensions having
regard to the particular window for which a blind is required and with which it
is to be used. The one edge it may preferably be the upper edge of this piece of
wire gauze is attached in any convenient and usual or other manner to a roller
of the proper length and of the desired diameter which roller is mounted in the
customary or other appropriate manner at or near and across it may preferably
be the top of the window as is the roller of an ordinary textile blind and either
inside or outside such window as may be expedient or desirable in each particular
case. The roller can when desired be a spring roller or can be operated as is
very common by a coiled spring fitted in any usual manner or it can be operated
as also is very common by an endless or other cord or otherwise by any ordinary
and convenient appliances or devices in such wise that it can be revolved in the
one direction to roll up the piece of wire gauze upon itself and in the other
direction to unroll the same off itself. For this purpose and to facilitate the
accomplishment of this operation the wire gauze as is indeed obvious must be
sufficiently fine and pliable to offer no great or undue impediment to and resistance
against such rolling and unrolling while at the same time as is indeed also obvious
the stouter and the stronger subject only to the aforesaid necessary condition
the wire gauze is and the finer and the smaller the mesh thereof is the better the
results exhibited by the same will be and the fire-resisting properties and qualities
thereof will by so much be enhanced and improved.

page_text: This piece of wire gauze so attached to and mounted on a roller whereto revolu-
tion can be given constitutes and is this my fire-resisting window blind which will
plainly for some considerable time at all events and in all cases prevent the flames
from bursting in at the window as is now so objectionably common of occurrence
and so dangerously rapid in execution.
A stretcher or bar can very conveniently be fitted when desired on and to the
opposite edge it may preferably be the lower edge of this blind and any metallic
or other hooks or other ordinary and suitable devices can be provided and fitted
on the wall or elsewhere in the appropriate positions to secure this free edge of
the blind as also the other edges thereof likewise when desired when such blind
has been unrolled and caused to cover the window and thereby such edge or
edges of the blind will be properly retained in position.
The lateral edges of the blind can be duly stiffened if desired it may be by
turning them in or folding them over upon themselves or by securing thereon or
thereover any appropriate binding or other like devices care of course being
taken that these edges are not thereby rendered too stiff to submit themselves
to the required easy rolling up of the blind upon the roller.
.
In the accompanying drawing I have shewn one of these my fire-resisting
window blinds as arranged and formed and adapted for an ordinary window
which blind is fitted and can be operated in one and a very common and convenient
manner.
A is an ordinary roller of the proper length and diameter provided with the
usual end flanges B which roller A can be revolved in its brackets or supporting
appliances in the one direction by the customary cord D passed round one end of
such roller A. E is a piece of wire gauze of the proper dimensions the upper edge
whereof is attached to the roller A and a stretcher F is fitted on and to the lower
edge thereof and to such stretcher F is connected the customary cord I by which
this blind can be unrolled off the roller A and pulled down to cover the window by
which action it is evident the cord I) will be wound upon this roller A. The
lateral edges K of this blind as also the lower edge L thereof are provided with a
suitable binding to cover and protect and it may be strengthen the same.
The piece of wire gauze that forms this blind may when desired not be attached
to its roller by the extreme edge thereof but such attachment may be arranged
and effected at a certain desired small distance from this extreme edge and it
may preferably be parallel therewith in which case when the blind is properly
unrolled from off the roller this part of the piece of wire gauze beyond such place
or line of attachment will by its inherent stiffness be caused to stand up off and
from the roller or can be made so to do by any springs or other usual and
suitable means and devices and thus will close or cover the space there may
occasionally be between the roller and the top or other part or edge of the
window.
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:-
:-
A window blind consisting of a piece of wire gauze attached by or near one edge
to a roller and capable of being rolled up on and unrolled off such roller
substantially as and for the purpose herein before described and declared.
