Purposes.
MATTHEW BUTCHER 20 Middlegate Hartlepool County of Durham Insurance
Agent do hereby declare the nature of this invention to be as follows:-
My invention relates to the improved construction of an apparatus to heat a
oven for baking & cooking purposes the said apparatus consists of a suitably formed
device for hot air to pass through a means to convey hot air into a squar shaped
flue or pip under the oven. The device is placed into the fire place close to the
side of the oven which prevents the fire or hot fuel from goen under the oven the
inwardly flue or pip aforesaid receves the hot air to the oven the said appliance
as above described can be adapted to aney ordeney oven or fire place Baking and
cooking is doon by hot air passing through means into a squar shaped flue or pip
to the oven from the fire that is in the fire place.

Improved Means for Heating Ovens for Baking and Cooking
Purposes.
1, MATTHEW BUTCHER, of 20 Middlegate, Hartlepool, in the County of
Durham, Insurance Agent, 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 :-
My invention relates to the construction of a device to be employed in connection
with a fire grate and oven, the main objects of the said device being to permit the
heated products of combustion and flame from the fire to pass freely into the oven
flue, while preventing the access of the coals or other fuel into the said flue and at
the same time providing means for heating a current of air and conducting it into
the same flue.
In the accompanying three sheets of drawings, which form part of this
specification and in which similar letters of reference denote similar parts
throughout,
Fig. 1, is an elevation,
Fig. 2 is a sectional elevation through A. A in Fig. 1, and
Fig. 3 is a plan, looking up from the bottom, of a device constructed in

page_text: Figs. 4, 5 and 6 are similar views of a slightly modified form of the same
device, and
Fig. 7 is an elevation of a fire grate and oven, shewing my said device applied
thereto.
Referring to Figs. 1, 2, 3 and 7, B is an ordinary firegrate, and C the oven at
side, having a flue D underneath it, passing vertically up the side further from the
fire and over the top in the usual way. The end of the flue D adjoining the fire
is open thereto, and such opening is closed by my aforesaid device, which consists
of a plate E, preferably formed of cast iron and having a series of parallel
horizontal slots, or openings F therein.
Each said slot is provided with a central bar H, preferably sloped, as shewn
clearly in Fig. 2, to deflect the flame and heated products of combustion from
the fire, which pass through the slots F, against the bottom of the oven.
On the back of the plate E is cast or affixed a flue J, having a sloping back and
open at top and bottom, as shewn. The plate E and flue J become very hot, and
air is drawn through the latter, highly heated by contact there with and then
discharged into the open flue.
In the modified form of the device, shewn in Figs. 4, 5 and 6, curved slots F
with curved bars H¹ are substituted for the straight slots and bars before
described.
It will be obvious that my arrangement effectually prevents the fuel getting
into the oven flue, while the heated air and products of combustion have free
access thereto, and baking or other cooking is done entirely by their means, with
a resulting economy in fuel.
The device can be varied in shape to fit the particular pattern of grate and oven
to which it is to be applied, and it can be used as an ordinary. fire dog, or cheek,
when no cooking is required to be done.
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. A device consisting of a plate E with openings For F¹, bars H or H¹ and a
Hue J, constructed substantially as and for the purposes herein set forth.
2. In combination with a grate B and oven C, a plate E having openings For F,
bars H or H¹ and a flue J, substantially as and for the purposes herein set forth.
