PROVISIONAL SPECIFICATION.
Improvements in and connected with Firescreens, Draught-regu-
lators, and Fireguards for Fireplaces.
We, ROBERT RAMAGE CRAW, of 36, Margaretta Terrace, Chelsea, London, S. W.,
Naval Architect, and JOHN ANDERSON CRAW, of 36, Margaretta Terrace, Chelsea,
London, S.W., Lecturer in Chemistry, do hereby declare the nature of this
invention to be as follows:-
The improvement of firescreens, draught-regulators and fireguards for fire-
places by the fitting into fireplaces of a permanent framework supporting a roller
or rollers to which a sheet, or sheets, of flexible material is fastened, and guiding
the movement and adjustment of the said sheet or sheets so as to close any
open portion of the fireplace, substantially as herein described.
In Fig. 1A is the framework fitted into the fireplace F and supporting the
roller B to which the flexible material C acting as a firescreen, draught-regulator
A is constructed so as to form a guide D for the move-
or fireguard is fastened.
ment of C and permit of its adjustment by means of the friction in the groove D of
a batton E attached to the bottom of C, and by a handle G attached to a tackle H
turning the roller B. Fig. 2 shows in detail the support of the roller B by
the framework A, and likewise the groove D formed in A.
C is to be made of fireproof cloth.
The remaining portions may be made of metal, earthenware, stone, wood, or a
combination of these.

Improvements in and connected with Firescreens, Draught-regu-
lators, and Fireguards for Fireplaces.
We, JOHN ANDERSON CRAW, of 36, Margaretta Terrace, Chelsea, London, S.W.,
Lecturer on Chemistry, and ROBERT RAMAGE CRAW, of 36, Margaretta Terrace,
Chelsea, London, S.W., Naval Architect, 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 improvement of firescreens draught-regulators and fireguards by the fitting.
into fireplaces or directly to grates of a permanent framework supporting a roller

page_text: or rollers to which a sheet of flexible material acting as a firescreen, draught-
regulator or fireguard is fastened and guiding the movement and adjustment of
the said sheet or sheets so as to close any open portion of the fireplace, substantially
as herein described.
In Figure 1 of drawings filed with our Provisional Specification, A is the frame-
work fitted into the fireplace F and supporting the roller B, to which the
flexible material C, acting as a firescreen, draught-regulator or fireguard is
fastened. A is constructed so as to form a guide for the movement of C and
permit of its adjustment by means of the friction in the groove 1) of a batton E
attached to the bottom of C, and by a handle G attached to a cord or the like H
turning the roller B. Fig. 2 of drawings filed with our Provisional Specification
shows in detail the support of the roller B by the framework A and likewise
the groove D formed in A.
The framework supporting the ends of the roller B may consist of two brackets
fastened directly on to the grate.
The roller B may be solid or hollow, and it may be grooved to receive the top
end of the screen so that the fastening of the same to the roller may be flush.
The roller may have wire wound round it to prevent the heat attacking same
when the hot screen is rolled up.
The adjustment of the screen may be made by attaching a ring to the cord
or the like H which may be placed over hooks or pins fastened at different heights
on one of the uprights of the permanent framing A or directly fastened to the
grate.
The adjustment may be made by locking the roller B in position by moving it
bodily to one side about one eighth of an inch so that a square end outside of one
of the supporting bearings will be pushed into that bearing which is provided with
a corresponding square hollow thus locking the roller at every quarter turn. The
locking end of the roller and the corresponding hollow in the bearing may both
he triangular in section or of polygonal shape.
The batton E may be of such a weight as to cause the screen to unroll by the
action of gravity. The weight of the screen C and batton E may be counter-
balanced by springs attached to B or by weights attached to B by a cord or the
like wound in the opposite direction to the cord or the like H.
The screen may be allowed to hang freely so that the draught draws it inwards
until it rests on the sides of the opening in the grate, thereby securing a better
draught.
The flexible material acting as a firescreen draught-regulator or fireguard may
be made entirely of fireproof cloth or of fireproof cloth preferably in the less
heated portions of the screen and in the more heated portions of thin flexible
metallic sheets as broad as obtainable fastened together by means of paper fasteners,
rivets, or soldering to form large sheets capable of being rolled, the
scams K in Fig. 3 or junctions of the narrower sheets being preferably vertical
to facilitate rolling; or the whole screen may be made of thin metallic sheets
united in the same manner as illustrated in Fig. 3 or of combinations of such
metallic sheets with fireproof cloth and asbestos.
The metallic portions of the screen may be covered on one or both sides with
fireproof cloth either plain or bearing an ornamental design, or may be covered
in the same manner by a thin layer of another metal or may be painted.
The framework and roller may be made of wood metal stone earthenware or
a combination of these.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
(1). The fitting of a permanent framework into fireplaces to support a screen of
flexible material of nature herein described.
(2). The fitting directly to grates of sunports for the said Anxihla matanial

page_text: (3). The use of a roller for the adjustment of a screen made of the said flexible
material.
(4). The grooving of the roller to receive the top end of the said screen..
(5). The winding of wire round the roller to prevent the screen herein described
from injuriously heating the roller.
(6). The adjustment of the screen herein described by means of a cord or the
like and hooks substantially as herein described.
(7). The adjustment of the said screen by means of a locking arrangement in
the manner herein described.
(8). The use of a batton attached to the said screen of weight sufficient to
cause the screen to unroll by the action of gravity.
(9). The use of thin flexible metallic sheets united together to form one large
sheet capable of being rolled.
(10). The use of the said sheets in combination with fireproof cloth
asbestos.
(11). The use of fireproof cloth to form the screen herein described.
or
(12). The covering of the metallic sheets herein described with a thin layer
of another metal or with fireproof cloth.
