Improvements in Draw Plates and Draught Regulators for Domestic
Fire Grates and Ranges.
CLIFFORD BERTRAM KILBY Masonic Jeweller 23 Gordon Street Lozells
Aston near Birmingham Warwickshire do hereby declare the nature of this
invention to be as follows:-
A collapsable draw plate or bonnet and draught regulator for fixing or connecting
to the round or square apertures leading to the chimneys of domestic fire grates.
It consists of several metallic ribs or leaves which taper from middle to ends and is
made according to the size of said apertures. It is folded and unfolded by being
rivetted together at the narrowest part of said ribs or leaves, the said rivets acting
It is fixed to said
as a pivot; each rib or leaf is shorter than the preceding one.
apertures by clamps bolts or other means, the said clamps bolts &c. being rivetted
on first rib or leaf and is so arranged that one or more ribs or leaves can be drawn
out to regulate the draught and prevent smoky chimney. It is also made so that
when drawn out to the full extent, the ribs or leaves are prevented from becoming
separated one from the other by a simple "catch" on each rib or leaf one being
turned up, the other down ;-when drawn out to full extent the inside rib or leaf
fits on the top fire bars and entirely closes the aperture, thus leaving ouly one
air passage viz. through the fire bars. It can be made in any metal, ornamental
ur plain and can easily be fixed, or unfixed for cleaning chimney by any one and
without tools.

1, CLIFFORD BERTRAM KILBY, Masonic Jeweller, 23 Gordon Street, Lozells,
Aston, near Birmingham, in the County of Warwick, 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 consists of improvements in draw plates and draught regulators
for domestic fire grates and ranges, my object being to construct a simple and
effective draw plate and regulator that can be conveniently attached to a fire grate
or range in such a manner as to permit of its being readily adjusted to give any
required intensity of draught and prevent smoking.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to.-
Figure 1 is a front elevation and Figure 2 a sectional side elevation representing

page_text: a kitchen range fitted with my improved draw plate or bonnet and draught
regulator.
Figures 3 and 4 are front and sectional side elevations respectively representing
the bonnet to a larger scale.
The same reference letters in the different views indicate the same parts.
The bonnet consists of several metallic ribs or leaves such as A tapering from
their middle towards each end and of such dimensions and so arranged as to
telescope within each other in the manner illustrated by the full lines at Figure 2,
the dotted lines in such figure representing the position of the leaves when
withdrawn from each other to the full extent. The ends of the leaves are pivotted
together by the pins B enabling them to be readily closed or telescoped within
each other or opened out or withdrawn as required. The ribs or leaves are
prevented from becoming separated when drawn out to the full extent by a simple
catch consisting of an outwardly projecting piece such as a on the rear end of the
leaves which abuts against a similar but inwardly projecting piece on the front
eud of the leaves.
I fix the bonnet preferably by means of clamping brackets C, such clamps being
rivetted upon the innermost leaf or rib.
One or more of the ribs can be drawn out to regulate the draught and prevent
smoking, or the bonnet may be extended to its full extent as illustrated, and thus
compelling the air to pass through the fire bars and creating an intense draught
through the fire.
The bonnet can be made in any metal and either plain or with any desired
ornamentation, and it can be very readily detached when necessary.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.-
1. An adjustable draw plate and draught regulator for a domestic fire grate or
range, substantially as described.
2. The combination and arrangement of a telescopic draw plate and draught
regulator substantially as described and as illustrated.
