I, MOSES WILSON of 20 St. Anne Street, Liverpool in the County of Lancaster
Ironmonger, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a cheap and simple mode of heating ovens, and of
preventing down-draughts.
I form, at the back of the fire-place, a plate, so arranged that the combustion gases
shall have to traverse to one side pass round the back of the plate and up the
chimney; also, however, having free access to the back of the oven beyond the
chimney. Furthermore, some of the gases, if the damper be not closed, pass under
the oven up the far side of the oven and over the top or along the back to the
chimney.
The space under the oven and at the other side of the fire-place is separated from
the latter by being a little raised above it and having an incline sloping towards the
fireplace. The consequence is if it is required to get great heat, coal can be heaped
up in the fire-place and lodged on the inclines, falling back into the fire if the latter
gets low.
Over the fire and a portion to one side or if desirable over the oven top flue is a
plate or hob for culinary vessels.
It will be obvious, however, that there can be an oven or hot water heating
apparatus on the side at present used only for the purpose of placing cooking vessels.
Also that in place of the oven being close on the furnace, the horizontal flue and
incline could be extended for a considerable distance, so as to allow more space for
pots and pans.
The arrangement of the back-plate is applicable for ordinary register grates of
fire-places, the flue passing underneath the hob on each side, then going behind the
back-plate and up the chimney. By this means I hope to prevent down-draughts in
chimneys to a very considerable extent.
Dated this 16th day of April 1888.

I MOSES WILSON of 20 St. Anne Street Liverpool in the County of Lancaster
Ironmonger 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 relates principally to Improvements in Cooking Stoves, ranges, or
fire Grates for household purposes and has for its objects the provision of improved
method and means for controlling the smoke and preventing down draughts.
In describing these improvements reference is made to the accompanying drawings.
Fig. 1 is a perspective illustration, the black lines shewing front of a self setting
range, the dotted lines interior of range. A is the hob plate the apron plate
of an ordinary kitchen range, D is the midfeather at the back of the fire, extending
under the oven and half way across the hobsido, I have a flue around the end
and at the back of the midfeather D, leading into the main flue or pipe E I also have
another flue under the oven, up one side and over the oven into main flue E.
By means of dampers I open or close these flues as desired.
Fig. 2. is a plan of range at F. shewing midfeather D.
G is an opening at the back of the midfeather direct under flue E. when the oven
Hlue is closed the smoke passes around the end and at the back of midfeather D into
Hue or pipe E as denoted by the arrows.
When the wind blows down the chimney, the smoke passes through the bottom of
flue at opening G under the grate bottom into a projecting canopy hanging on bars,
or side hooks in front of fire.
The particular shape of the midfeather may be varied as occasion requires, in small
selfsetting ranges. prefer a piece of cast iron the end under hob forming an obtuse
angle, in larger ranges I prefer the midfeather straight, with water way, to act as
back boiler.
In a sham range (that is not self setting) I use either solid iron, brick, tile or a
boiler as before described.
I am aware that prior to my invention, ranges have been fixed with a midfeather
under oven. I do not therefore claim this part as my invention.
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,
In a fire grate or cooking stove the combination therewith of a midfeather D at the
back of the fire and extending under the hob, as an improved method and means of
controlling the smoke and preventing down draught in chimneys.
