COMPLETE SPECIFICATION.
A New or Improved Device for Fire Places, Stoves, Furnaces, and
the like.
We GEORGE BIRDSEY CLARKE, 9 Montpelier Road, St. Johns College Road
London N.W., Gentleman and SAMUEL KRINKS 235-236 Icknield Street
Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of our said invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
Our invention has for its object a new or improved device for fire places, stoves,
furnaces and the like which forms a fender or inner fender to the fire place for the
purpose of directing, concentrating and increaseing the supply of air to the fuel so
as to ensure antracite coal, coke or other smokeless or slow combustion fuel always
being kept in a glow without unnecessarily burning the fuel away.
In order that our invention may be clearly understood and easily carried into
practical effect we have appended hereunto two double sized sheets of drawings upon
which we have illustrated examples of our improved device.
Figure 1 is a front elevation of our device.
Figure 2 is a plan view of Figure 1.
Figure 3 is a perspective view of the frame which supports the screen.
In carrying our invention into practice we form our device or screen from a
number of plates or segments A made of metal or other suitable material and
connected together by the links a' or in any other suitable manner. At the back
of each plate or segment is formed the hook a² see Figure 7 for attaching them on
to the bars of the frame and near the top on the front of each of these plates or
segments is formed the eye piece ³ into which the hook or catch b¹ formed on each
of the air conductors B fits as shown at Figure 4. These air conductors B are fixed
at a slight angle to the face of the screen and can be easily attached or detached
and conduct the air to the fuel through the bottom bar of the grate or to the bottom
of the furnace. In some of the plates or segments we form a hole into which we
fit one of the air conductors C which are preferably made of heat conducting metal,
placed so as to conduct the air under the fire bars to the fuel. These air conductors Ć
have a flange c¹ formed at one end see Figures 5 and 6 which butts against the face
of the plate or segment and is held in position by the screw c² or its equivalent.
Fitted in the interior of each of these conductors C is the hinged or pivotted
diaphragm or regulator which can be opened or closed for regulating the supply of
air. The air conductors B2 are formed shorter than the conductors B so as to allow
a free passage for the air into the conductors C.
The frame to which the plates or segments are attached is formed from sheet iron
or other metal and consists of the top and bottom bars f¹ and f². These bars are
made adjustable so as to lengthen or shorten the frame and are fixed by means of
the screws for their equivalents to the supports f f & f³ The holes fo formed
in these top and bottom bars are provided for the purpose of adjusting the supports
to suit various sized grates or furnaces. These supports are also formed from sheet
iron or other metal and the supports or uprights fs are hinged at to the

page_text: supports and 5 and also at f to the base pieces f10 and f" which are pivotted
together by the cross pieces 12. The other ends of the supports f and fare
connected to the base pieces by the screws fis, the holes f14 being provided so as to
adjust or vary the angle at which the screen leans.
The screen is formed in segments so as to enable it to be lengthened or shortened
to suit various sized fire grates or furnaces.
When the required number of segments have been attached to the bars flas
herein before described the screen is placed in position in front of the fire grate, the
base portion and supports of the frame fitting under the fire grate. The length of
the segments or plates vary according to the height of the fire grate.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
CLAIMS.
First: A new or improved device for fire places, stoves, furnaces and the like
formed in parts or segments having air conductors such as C for conducting air
under the fire bars and air conductors such as B for conducting air into the front of
the fire or furnace in the manner and for the purpose substantially as herein before
described and as shewn upon the accompanying sheets of drawings.
Second: In the device or screen as claimed in the preceeding claim providing
the air conductors C with a revolving disc or regulator substantially as described
and as shown upon the drawings.
Third In the device or screen as claimed in the preceeding claims the
adjustable frame for supporting the segments or plates in the manner and for
the purpose substantially as herein set forth and as shown upon the drawings.
Dated this 11th day of September 1897.
