PROVISIONAL SPECIFICATION.
Improvements in Fire-places for Kitchen and other uses.
I JAMES BURFORD of Leamington Kitchener Works Avon Street in the Town
and County of Warwick Iron Founder and Kitchen-range Manufacturer do hereby
declare the nature of this invention to be as follows:-
These improvements are mainly designed for use in kitchen ranges or kitcheners
but are partly applicable for use in other descriptions of fire places of domestic or
like character.
The improvements as applied to kitcheners, either closed fire or combined open
and closed fire, or open fire, consist of a movable perforated bottom plate, or series
of bars, hinged rearwardly to the back bar or support thereof, which may be socketed,
the front of this bottom plate or grille on which the fire material rests has attached
to it one end of an arc or curved shaped toothed, pin, or rack bar, which travels in
and if need be is guided by a slot or opening in a fixed bar below the fire and
into the teeth, pins, or racking of this curved bar take the projections, or teeth, of
a wheel, or rotatory part, correspondingly mounted in bearings, said rotatory part
being operable by means of a key adapted to take into or onto a squared or other
shaped opening or projection, or from such rotatory part.
The back of the fire is designed to he kept at or about one height relatively to
the boiler flue opening whilst the height of the front of the fire is variable by
raising the hottom support.
The upper front of the fire place may be closed by a door formed with
chambers projecting into the space over the fire and perforated with air passages
from exterior to interior.
The sides of the fire place may be hollow and perforated to conduct air, which
becomes heated in its passage, from below to the space above the fire.
The rear upper part of the space of or above the fire may be supplied with heated
air, to aid the draught and facilitate combustion, by means of conduits from below,
passing up in front of the back plate and delivering air through perforations in
projecting parts or nozzles, louvre plates, below serving to facilitate admixture of the
products of combustion and such heated air and so promote better ventilation.
.
By existing arrangements bottom plates of fireplaces have been raised vertically
and sides have been drawn in horizontally but by means of an are shaped or curved
toothed bar operated by a corresponding rotatory part the lifting bar can be
moved so as not to project inconveniently downwards but is stowable rearwardly
in a small depth.

COMPLETE SPECIFICATION.
Improvements in Fire-places for Kitchen and other uses.
JAMES BURFORD of Leamington Kitchener Works, Avon Street in the Town-
and County of Warwick, Iron Founder and Kitchen range 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:
These improvements are mainly designed for use in kitchen ranges or kitcheners

page_text: Figure 1, by a vertical section shews one form of my invention suitable for
application to a closed fire kitchener, (taken on the line. Figure 2) said range
being convertible to an open fire by removal of caps and panels and the door f
opened (Fig. 6).
Figure 2 is a front view of the parts shewn in Figure 1.
Figure 3 is a side view of the oven side of the fire place wall to the left hand side
of Figure 2.
Figure 4 is a front view of the parts for supplying heated air to the rear of and
above the fire, separately drawn, and also serving to divide up the flame and facilitate
admixture of air and gases.
Figure 5. is a modified arrangement of the apparatus shewn in Figure 4.
Figure 6 is a general view to a smaller scale shewing a portion of a kitchener with
my invention applied, and
Figure 7. is a detail shewing the toothed rack e separately.
a a are the checks or side walls of the fire and ash places each being formed
with a curved flange at their upper edges a a³ upon which rest the fire
checks a³, a7.
a², a³, are ears by which connection between the cheeks and the front of the range
is made. is the bottom or grate on which the fire material rests, and is formed of
a series of bars, capable of swinging by having its back bar or rod carried in holes
or slots as a in the sides a a'. To the front of the bottom plate b is attached one
end of a curved toothed rack c (see Figure 7) into the teeth of which take the cogs
or rods of the rotatory part d. This rotatory part is operable by the handle d' and

page_text: is mounted at its rearward end in bearings el in the back plate e, and at its front
end at in the lower portion of the front frame f of the grate or is equivalently
supported and operated. By turning the handled the bottom plate & can be raised,
or lowered, as desired to adjust area of the fire box. The upper part of this frame f
is closed by a suitable door f2 (see Figure 6) in the ordinary manner.
Air enters the side plate a at the opening a and passes up the channel or
conduit a formed by the flange a on the side plate a, and the wall, or
partition, a3 and out at the holes a" on to the fire material, having been heated in
such passago, through the heated chambers thus formed.
For the purpose of heating the bottom of the oven an opening a¹ is formed in
the fire cheek as, through which the flame and heated air enters and passes down
the conduit a formed by the flange a" and the wall a¹³ under the oven and thence
away by a suitable conduit to the chimney flue not shewn.
The side plate a¹ is provided with two entrances similar to the opening a¹0 for
air, one of which appears at a", and the other in line rearwardly thereof, and a
conduit a¹ and outlet holes a", in manner similar to the like provided to the side
plate a.
In order to supply air to the rear upper portion of the fire, the back plate e which
rests on projections a² a² formed on the sides a a¹ has cast on it at its rear side
projecting pieces or lugs with holes e² e² into which fit the lower ends of conduits e³ e³,
which conduits extend upwardly and lead into a cross conduit et having projecting
nozzles e and holes e. Air enters the conduits e³ and whilst passing up becomes
heated, and issues at ef onto the fire material promoting combustion of the denser
gases and securing better ventilation than would otherwise take place. e e' are louvre
plates secured to the conduits e³ ³, and serve to break up and admix the products of
combustion and the heated air but these are not essential in this form as this may be
secured by equivalent devices.
In the modified form shewn in Figure 5 the back plate e is formed as in Figure 4
but has a slotted plate e¹ which plate has flanges formed around the three sides at
e, and elo so as to form one large channel for the air to pass up whilst being heated
and on its way to the exit openings e e e are the slots cut in the face of the plate e¹²
for the purpose of admixing the heated air and products of combustion.
The handle or winch d' is removable when not in use.
The arrows indicate the directions of flow of the air, gas and flames.
The dotted lines in Figure 1 represent the adjustable rising bottom in its most
upraised position the full lines shewing it lowered to nearly its lowest position.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination or arrangement and use in fire places for kitchen and other
uses of the parts forming the adjustable swing bottom, the hollow cheeks with
opening in one of sanie, the passages therefrom downwardly to and under the
oven, the air passages a" for conveying fresh air from below into the fire chamber
or box over the fuel being consumed, and the back air supplying passages e³ and
nozzles es, and front fire doors, air jets or nozzles f³ substantially as herein described
and shewn.
2. The combination or arrangement and use of parts of kitchen ranges or fire
places for other uses, so as to admit of the height of the fire at the back being kept
uniform relatively to the boiler flue opening, whilst admitting of the front of the fire
being varied in height, the conveyance of heated gases or flame to below the oven
and the admixture of fresh air with the products of combustion above the level of the
fire substantially as and for the purposes set forth.
3. In kitcheners or like fire places the arrangement or combination with the sides,
or cheeks and other parts, of a hinged bottom to support the fuel, a curved or arc
shaped rack bar or like support, engaging with a toothed roller or like operating part

page_text: capable of rotation for adjustment by a handle or winch or otherwise substantially as
and for the purpose set forth.
4. The general arrangement or combination of the parts of a kitchener substantially
as and for the purposes herein shewn and described.
Dated the 13th day of February 1890.
