of the Commissioners of Patents, with bis Petition, on the 24th August
1865.
I, FREDERICK THOMAS, of 72, Bishopsgate Street Within, in the City of
London, Cooking Apparatus Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE METHOD OF HEATING THE OVENS
AND BOILERS OF KITCHEN RANGES OR COOKING STOVES," to be as follows, that is to
say:-
The object of this Invention is an improved method of heating the oven or
ovens of such kitchen ranges or cooking stoves as have an oven or ovens
placed on either side, or on both sides of the fire-place or fire-grate thereof;
and also an improved method of heating the boiler or boilers of kitchen ranges
or cooking stoves having a boiler or boilers placed on either side, or on both
sides, or at the back of the fire-place or fire-grate thereof.
The manner in which these objects are accomplished is, by so forming and
.placing an enclosed hollow space or spaces, flue or flues, underneath, or under-
neath and around, or partially underneath or around an oven or ovens placed
at the side or sides of the fire-place, or underneath and around, or partially
underneath or around a boiler or boilers, placed at the side or sides, or at the
back of the fire-place, or underneath or underneath and around both or all,-
any or all of the said oven or ovens, boiler or boilers, as that the said hollow

page_text: space or spaces, flue or flues, shall more or less extend and continue, either
underneath the bottom of the fire-place or fire-grate, or underneath a hollow
space or spaces, flue or flues, formed at or adjoining to the side or sides of the
fire-place or fire-grate, or, underneath a hollow space or spaces, flue or flues,
formed at or adjoining to the back of the fire-place or fire-grate, or more or
less underneath some or all of these; and by so arranging and constructing
and more or less connecting the said hollow space or spaces, flue or flues, as
that beat may be made or allowed to pass from the fire, either through or
from the bottom, or through or from the back, or through or from the side or
sides of the fire-place or fire-grate, or through or from either one or any or
all of these, into or through either one or any or all of the aforesaid hollow
space or spaces, flue or flues, and may then and thus be used or employed to
heat the oven or ovens, boiler or boilers, by being made or allowed to pass
either under, or around, or into the said oven or ovens, boiler or boilers, either
with or without the employment of a perforated or hollow or double bottom to
the said oven or ovens, or otherwise to effect the said object and purpose of
heating the said oven or ovens, boiler or boilers.
"
The aforesaid hollow space or spaces, flue or flues, may be made, formed,
or constructed either of brick, or stone, or metal, or of any two of these com-
bined, and may be so made, formed, or constructed, either as part of the con-
struction of the kitchen range or cooking stove itself, or as part of the method
or manner in which the kitchen range or cooking stove is " set or "fixed;"
and the aforesaid hollow space or spaces, flue or flues, may be or may not be
continued into or connected with a passage or passages, space or spaces, flue
or flues, passing from the upper or any other part thereof into the chimney or
into any other flue or passage or hollow space constructed in or around or
over any part of the kitchen range or cooking stove, and continued into or
connected with the chimney.
In applying the aforesaid improvements to the construction of kitchen
ranges or cooking stoves, of which the bottom of the fire-place or fire-grate is
so constructed as to be moveable at pleasure, or is constructed as to be
capable of being made to ascend or descend at pleasure by means of appliances
thereto attached or connected for that purpose. I so form and construct the
said moveable bottom of the fire-place or fire-grate, as that in being made to
move, ascend, or descend as aforesaid, the entrance of air or of draught into the
hollow space or spaces, flue or flues herein-before described, otherwise than
through or over the fire is, so far as may be regulated, shut off and prevented;
or otherwise I so construct the aforesaid hollow or hollow flue or flues as to
effect the aforesaid last-mentioned object or intention.

page_text: The aforesaid method of heating an oven or ovens, boiler or boilers, so
placed as aforesaid, may be applied to kitchen ranges or cooking stoves
having their places more or less enclosed or more or less open, and to kitchen
ranges or cooking stoves which have or which have not the upper part of
the oven or ovens, boiler or boilers, heated by means of a draught of heat
passed from the fire over the top of the said oven or ovens, boiler or boilers.
