page_text: A Fireproof Shutter Combined with a Reflector for Windows.
ALFRED JAMES BROWN, of Holly Bank, Alexandra Park Road, Wood Green,
County of Middlesex, Warehouseman, do hereby declare the nature of this inven-
tion to be as follows:-
The invention consists of a shutter on the one side fireproof material and on
the other side bright reflecting glass, so that it can light a room through the
window as a reflector or make the window fireproof when closed.
When open and acting as a reflector it is secured at the bottom of the window
with rod & eyes and suspended at any angle necessary for light by chains one
on each top side going thro' a hole in the wall at each side of the window-
which can be hooked by arrangements provided to hang at an angle of 45 degrees
or any angle or to be pulled up in case of fire & fastened close to the window-it
can be arranged to go quite into the brickwork of the window or just flush to
the surface and overlapping the frame.
A Fireproof Shutter Combined with a Reflector for Windows.
I, ALFRED JAMES BROWN, of Holly Bank, Alexandra Park Road, Wood Green,
in the County of Middlesex, Warehouseman, 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:
―
This invention relates to a device which is intended to serve the double purpose
of a fire-proof shutter for use during the night or at other times as required, and
also of a reflector for reflecting light into the room to the windows of which the
device is applied. And in order that my invention may clearly understood I will
proceed to describe the same with reference to the accompanying two sheets of
drawings in which Figure 1 represents in vertical section the outer walls of two
floors of a building to the windows of which my invention is applied. Figure 2
PR71

page_text: is a vertical section of a window to a larger scale shewing my improved shutter
in the closed position. Figure 3 is a back view of such a shutter, and Figures 4
and 4+,
and 5, 6 and 6, and 7 and 74 are elevations and sections respectively
to a larger scale illustrating various forms of construction of my shutter.
Similar letters relate to like parts in all the figures of the drawings.
The shutter may be constructed somewhat after the manner of the well known
form of window reflector in which the lower part is hinged to the window-frame
or to the wall of the building, and the upper part so suspended that, when in its
normal position, it is at about an angle of 45 degrees with the face of the window.
The inner or reflecting face of the shutter is of silvered glass or mirror of the
kind usually employed for such purposes, or of any other suitable light-reflecting
medium. The back of the shutter is, however, made more or less fire-proof by
the employment of asbestos or other suitable fire-resisting material or combination
of materials.
The shutter is adapted to be drawn up more or less close to the window, or
let out to the required angle, by chains or other suitable devices operated from
the interior of the room as desired, and may be adapted to fit into the structural
window opening or to entirely cover the same.
In the upper part of Figure 1 one shutter is shewn applied to the window, but
in the lower part of the same figure two shutters are shewn, each one being
arranged to act independently of the other. A are the shutters, B the hinges
attached in this case to the sill C of the window frames D. E are chains attached
at F to the shutters A, passing over the pulleys G and fastened by cleats or hooks,
or in any other convenient manner, in the interior of the room.
It will be understood that while the shutters A are in the position shewn in
Figure 1 their inner or reflecting surfaces A' will serve to reflect light into the
rooms in the ordinary manner, but when drawn up into the closed position (see
Figure 2) their outer or fire-resisting surfaces A will serve to protect the window-
openings or the windows themselves from the destructive action of radiant heat,
Hame, sparks or embers, to which they may be subjected in the event of a fire
breaking out in the neighbourhood of the building so protected.
The shufter A may be constructed in any convenient or suitable manner, but
I prefer that the frame shall be of metal us is illustrated in the various Figures 3
to 7. In Figures 2, 3, 4, and 4. H is the frame, I the glass, J asbestos card-
board. Ka sheet metal backing. The glass I, the asbestos J and the backing K
may be placed in the frame before the bottom side thereof is fixed, and the latter
may conveniently be held in place by the hinge pin B as shewn. L is a filling
or bedding of felt, white-lead, putty or other suitable substance.
In Figures 5 and 5 the frame H is of such a section as to permit of the glass
being placed in position from the back of the frame, a filling piece I being
employed as shewu.
In Figures 6 and 6, the asbestos J and glass I are placed in position from the
front, the front portion of the frame being afterwards attached by screws or
otherwise.
In Figures 7 and 74, the glass I. and asbestos J are placed in position from the
back and the portions N of the frame are then bent over so as to retain the
whole in place. It will be seen that in Figures 5, 6, and 7 the metal back-
ing K is dispensed with, the asbestos card-board or other fire-proof material being
uncovered.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. A combined fire-proof and reflecting shutter the outer portion or book of

page_text: which is composed of fire-resisting material and the inner portion or front of
light-reflecting material, substantially as described.
Second. A combined fire-proof and reflecting shutter constructed and applied
substantially as described with reference to the drawings
