I, WILLIAM COULSON PARKINSON, trading as W. Parkinson and Company, of
Bellbarn Road, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
66
This invention relates to gas fires and like gas-heating apparatus in which a
mixture of gas and atmospheric air is burnt and made to play upon artificial
fuel" such as asbestos, fire-clay or iron balls or the like placed within a grate
or fire place, and has for its object to create or accelerate the creation of a draught
within a chimney and thereby preventing obnoxious fumes entering a room,
particularly on the first lighting of a fire.
The invention consists in mounting in the upper part of the fire place and above
the grate or part in which the fuel is placed, a pull-out, draw-down or other
supplementary hood or draw plate, one form consisting of a quadrant shaped hood
or cowl open at back or top and bottom and jointed at and turning upon the back
angle as a centre of motion, and with the front part curved, the whole lying with
a like-shaped or other suitable canopy made a part of, or attached to the upper
portion of the gas-fire grate or frame.
Normally the hinged or swinging hood lies under the canopy, but when the
draught of a gas-fire requires to be accelerated, and the whole of the fumes arising
from a gas fire, on it first being lighted, to be properly taken away, without any
being allowed to escape into a room, then the said hood is drawn or pulled down
from under the canopy, turns upon the hinge at its inner end, and thus is made to
overhang, or almost entirely hood over the upper part of the grate, whereby the
draught is materially increased and the combustion of the fire is rendered more
perfect.
Suitable guides and stops for controlling and limiting the movement of the
hood may be provided and instead of the cowl, hood or draw plate turning down
anto its position of use by a radial movement, it may be arranged to slide down,
either vertically or, obliquely, or it may slide horizontally from the side or be in
two or more parts sliding from both the sides, and move, preferably, in every case,
in guides, runners or grooves for steadying the movement, and further, adjustable
or other stops or like means are fitted by which the extent to which the draw
plates are let down over the open front of the fire place can be regulated.
As a further modification, the draw plate may be in the form of a door or doors,
horizontally or vertically pivoted to the canopy or to the sides of the fire and which
are turned over the upper part of the grate on the draught requiring to be
accelerated.

page_text: I, WILLIAM COULSON PARKINSON, trading as. W. Parkinson and Company, of
Bell-barn Road, in the City of Birmingham, 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:
This invention relates to gas fires and like gas-heating apparatus in which a
mixture of gas and atmospheric air is burnt and made to play upon artificial
"fuel "such as asbestos, fire-clay or iron balls or the like placed within a grate
or fire place, and has for its object to create or accelerate the creation of, a draught
within a chimney and thereby preventing obnoxious fumes entering a room,
particularly on the first lighting of a fire.
The invention consists in mounting in the upper part of the fire place and above
the grate or part in which the fuel is placed, a pull-out, draw-down, hinged, or
other supplementary hood, draw plate or draught accelerator, working in suitable
guides and preferably provided with means for retaining it in a raised, or partly
raised position, yet capable of being easily released and lowered into.its. position
of use.
Figure 1 of the accompanying drawings represents a front elevation of a gas fire
provided with a vertically-sliding pull-arm draw plate or draught accelerator,
working in upright guides at the side of the opening in the grate and provided with
means for retaining it in its fully raised position or in any intermediate position.
This view shows the plate raised.
Figure 2 is a like view as Figure 1, but with, the draught accelerating plate
lowered or let down into its position of use.
Figure 3 is a vertical section upon the dotted line x, Figure 2 and Figure 4 a
horizontal section of the same upon the dotted line x¹.
Figure 5 is a like vertical section, as. Figure 3, but upon an enlarged scale.

a is the grate or fire" a¹ the part, wherein the fuel" is. disposed for the
flames from the burner (not shown) to play upon and a³ is the usual fixed canopy
or hood, overhanging the open space, a, above the fire and leading to the chimney
up which the products of combustion pass away. Located within this space and
coming, when raised, close against the inner side of the fixed canopy or hood, is
a sliding or pull-down draw-plate or supplementary hood b, having a space b¹,
at its bottom part and with its edges running, with a certain amount of loose
play, in guides a³, at the sides of the space at. The outline of the space b¹, may
correspond in shape to that of the bottom edge of the fixed hood, so that when the
sliding hood is fully raised the two edges,coincide and the said hood is retained
in its lifted position, and completely out of sight, by the broad part c¹, of the
lifting stud c, being made to engage and lie within the cross end d', of a T-shaped
gap d, in the edge of the canopy a³, whilst to release the plate the stud is. given an
outward movement (taking the plate with it), so as to bring the neck c³, over the
vertical part d, of the gap, thus. admitting of, the accelerator plate being lowered
to the position shown in Figures 2 and 5, in which it partially fills up the space a*;
and causes an increased draught of air through, the part. left open, whereby any
obnoxious fumes which may arise on the first lighting of the burner, or at other.
times, are taken up the chimney without being allowed to escape into an apartment.
In the event that it is desired to only partially lower or raise the plate, the
upper edge 63, or equivalent part may, have a hook shaped projection or rib 64,
adapted to be engaged with one or other of a series of corresponding ribs or snugs
such as as, formed or disposed upon the inside of the fixed canopy, or any equivalent
means may be arranged for effecting this purpose.

page_text: Instead of the plate sliding vertically as in the arrangement described, it may
slide obliquely as represented in Figure 6, in which the like parts are marked
with the same letters of reference as the corresponding parts in Figures 1 to 5.
Figure 7 represents another form of movable hood arranged and operating
according to another form of my invention. The draught accelerator, in this
arrangement, consists of a quadrant shaped hood or cowl b, open at back or top 61
and bottom 63, and jointed and turning upon a pivot 64, at the back angle 65, as
a centre of motion, and with the front part 66, curved, the whole lying with a
like-shaped or other suitable fixed canopy or hood as, made a part of, or attached
to, the upper portion of the gas-fire grate or frame a, overhanging the front open
space a, at the bottom of which is the grate a¹, for containing the fuel.
Normally the hinged or swinging hood lies under the canopy, and is secured
thereby by the lifting stud c, engaging the slot d, as in the first arrangement, the
slot 68 at the joint allowing of the supplementary canopy making the necessary
inward or outward movement for releasing it, but when the draught of a gas-fire
requires to be accelerated for properly taking away the whole of the fumes arising
from a gas fire, such as on it first being lighted, without any being allowed to
escape into a room, then the said hood is drawn or pulled down from under the
canopy, turning upon the hinge at its inner end, and thus is made to overhang,
or almost entirely hood over the upper part of the grate, whereby the draught is
materially increased and the combustion of the fire is rendered more perfect.
Suitable guides and stops for controlling and limiting the movement of the
hood may be provided and instead of the supplementary cowl, hood or draw plate
turning down into its position of use by a radial movement, or being arranged
to slide down vertically or obliquely as described it may slide horizontally from
the side as represented in Figure 8, in which it is in two (or more) parts b, b¹,
respectively sliding from the opposite sides a¹, a³, of the grate and moving prefer-
ably, in guides runners or grooves a³, a, at top and bottom for steadying the
movement, and further, adjustable or other stops or like means may be fitted by
which the extent to which the draw plates may be drawn across the open front
of the fire place can be regulated.
As a further modification of my invention and which is represented in Figure 9,
the draw plate may be in the form of a door or doors b, b¹, vertically pivoted at 63, 64,
to the sides a¹, a³," of the fire a and which are turned over or across the upper part
of the grate on the draught requiring to be accelerated.
Or the said door or doors may be horizontally pivoted to the bottom edge of the
fixed hood, or to any other equivalent part of the fire opposite the front opening.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
First Providing at the upper part of a gas fire, or in the space between the
fixed canopy or hood and the grate wherein the fuel is placed, a sliding or hinged
supplementary hood, draw plate or draught accelerator, substantially as, and for
the purpose as described and set forth.
Secondly: Providing at the upper part of a gas fire, and within the space
between the fixed canopy or hood and the grate, a vertically or obliquely sliding
supplementary hood, draw plate or draught accelerator, with edges or parts working
in guides and provided with means for retaining it in its fully or partly raised
positions, substantially as described and set forth in Figures 1 to 6.
Thirdly Providing at the upper part of a gas fire, and within the space
between the fixed canopy or hood and the grate, with a quadrant shaped and
jointed supplementary hood, cowl or draught accelerator, provided with means for
retaining it in its raised position, substantially as described and set forth in
Figure 7.
Fourthly: Providing within or adjacent to the space above the grate of a gas
fire, a horizontally sliding supplementary draw plate or plates, adapted to slide

page_text: into position to form a draught accelerator, from the side or sides of the framing
of the fire, substantially as described and set forth in Figure 8.
Fifthly Providing within or adjacent to the space above the grate of a gas
fire a supplementary door or doors vertically or horizontally hinged to a side or
sides or part or parts of the fire, substantially as and for the purpose as described
and set forth in Figure 9.
