Improvements in the Construction of Fire-resisting Curtains
and Doors.
I, EDMUND. TAYLOR, of Tower Chambers, Finsbury Pavement, London E.C.,
Managing Director of E. & E. Taylor Limited, of the same place, Engineers,
do hereby declare the nature of my said invention to be as follows:-
My invention relates to the construction of fire-resisting curtains for closing the
proscenium openings of theatres, music halls, concert halls, and other places where
such curtains are useful in preventing the spread of fire; and also to the construc-
tion of fire-resisting doors for party walls, and other structures where such doors
are useful; and my invention consists in effecting improvements therein, for the
purpose of increasing the fire-resisting properties of such curtains and doors.
In forming the outer frame of my improved curtains, 1 use channel iron or steel,
of suitable scantling, secured at the corners by brackets or other well-known means.
Intermediate frames, and other vertical, horizontal, and diagonal rods or bars,
consisting of round, angle, H, T, or channel iron, are bolted or otherwise secured
together and to the outer frame, so as to render the same sufficiently rigid, and to
enable me to divide the same into compartments to prevent the shifting of the
packing. I cover this frame, on both sides, with boards or plates of asbestos of
suitable thickness, and fill the enclosed space or spaces with silicate cotton or
asbestos packing, the whole being secured together by bolts, asbestos cords, wire,
or any other suitable material, so as to form a compact, firm wall, of uninflammable
and incombustible material. The curtain is fitted in suitable grooves next to the
wall of the proscenium, so that it may be raised and lowered by hydraulic or
other suitable power.
In applying my invention to the construction of fire-resisting doors, the frames
are similarly formed of light steel, of round, tubular, angle, H, T, or channel
section, as above described, and covered on both sides with asbestos plates, riveted
or bolted to the frame. The cellular spaces between the plates may either be left.
to form air spaces, or may be filled in with silicate cotton, or other fire-proof
material. The external faces of the plates are rendered damp and water proof.

statement:-
My invention relates to the construction of fire-resisting curtains for closing the
proscenium openings of theatres, music halls, concert halls, and other places where
such curtains are useful in preventing the spread of fire; and also to the con-
struction of fire-resisting doors for party walls, and other structures where such
doors are useful; and my invention consists in effecting improvements therein, for
the purpose of increasing the fire-resisting properties of such curtains and doors.
In forming the outer frame of my improved curtains, I use channel iron or
steel, of suitable scantling, secured at the corners by brackets or other well-known
means. Intermediate frames, and other vertical, horizontal, and diagonal rods or
bars, consisting of round, angle, H, T, or channel iron, are bolted or otherwise
secured together and to the outer frame, so as to render the same sufficiently rigid,
and to enable me to divide the same into compartments to prevent the shifting of
the packing. I cover this frame, on both sides, with boards or plates of asbestos
of suitable thickness, and fill the enclosed space or spaces with silicate cotton or
asbestos packing, the whole being secured together by bolts, asbestos cords, wire,
or any other suitable material, so as to form a compact, firm wall, of uninflammable
and incombustible material. The curtain is fitted in suitable grooves next to the
wall of the proscenium, so that it may be raised and lowered by hydraulic or other
suitable power.
In applying my invention to the construction of fire-resisting doors, the frames
are similarly formed of light steel, of round, tubular, angle, H, T, or channel
section, as above described, and covered on both sides with asbestos plates, riveted
or bolted to the frame. The cellular spaces between the plates may either be left
to form air spaces, or may be filled in with silicate cotton, or other fire-proof
material. The external faces of the plates are rendered damp and water proof.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. is an elevation of a fire-resisting curtain, suitable for closing the
proscenium openings of theatres, music halls, concert halls, and the like.
Fig. 2 is a vertical section, and Fig. 3 a horizontal section of portions of Fig. 1.
As shown in the drawings, the sides are formed of asbestos plates 4, 4, stiffened
and supported by wrought iron or steel joists 5, 5, and by H, T, or other iron or
steel bars 6, 6, bolts 7, 7, brackets 8, 8, diagonal rods or bars 9, 9, and channel iron
or steel 10, 10. Other rods or bars are added where necessary, in order to impart
the necessary stiffness or rigidity to the structure. The joists 5, 5, may be utilised
in the formation of separate air spaces, or such spaces may be filled with silicate
cotton, asbestos, or other suitable packing. Transverse plates being fitted at con-
venient distances apart to prevent the packing becoming displaced, and to preserve
the homogeneity of the structure.
In the construction of fire-resisting doors, the frames are similarly formed, as
above described in relation to fire-resisting curtains, with obvious modifications for
the purpose of providing additional stiffness (if necessary); the external faces of
the plates being rendered proof against damp and moisture by means of suitable
paint applied thereto.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in the construction of fire-resisting curtains and doors,
substantially as and for the purposes herein before described and illustrated by the
drawings.
2. In the construction of fire-resisting curtains and doors, the combination of a
framing, consisting of channel iron or steel, united at the corners by brackets;

page_text: intermiate frames; diagonal and other stays; arranged so as to form separate
compaments for air or incombustible materials; the external sides consisting of
i plates of asbestos, the whole being bolted together, substantially as
ore described and illustrated by the drawings.
