PROVISIONAL SPECIFICATION.
Improvements in the Construction of Domestic Fire Places.
1, HENRY SUTCLIFFE of No. 15 Industrial Street, Todmorden, Yorkshire,
Whitesmith, do hereby declare the nature of this invention to be as follows:-
This invention has reference to the backs of domestic fire places, my improve-
ments therein consisting in constructing them so as to admit heated air to the back
of the fire for the purpose of accelerating combustion and lessening or consuming
the smoke given off the fuel.
In constructing fire places according to my invention I form the back of the fire
of bricks having diagonal cavities or diagonal perforations in them. I also form a
chamber behind these cavity bricks, the bottom of such chamber being in communi-
cation with a passage or opening under the fire grate for the admission of air. The
top of the chamber behind the cavity bricks is covered over by a plate made of
iron, fire-clay or other material, so that on atmospheric air entering the chamber
it is drawn through the diagonal cavities into the fire and increases combustion.
The bricks having the cavities or apertures in them may be formed in two or
more parts.

COMPLETE SPECIFICATION.
Improvements in the Construction of Domestio Fire Places.
I, HENRY SUTOLIFFE, of No. 15 Industrial Street, Todmorden, Yorkshire,
Whitesmith, 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 has reference to the backs of domestic fire places, my improve-
ments therein consisting in constructing them so as to admit heated air to the back
of the fire, for the purpose of accelerating combustion and lessening or consuming
the smoke given off the fuel.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
drawing which illustrates my improved fire back.
A represents the fire bars, and B a chamber which is formed by building hollow
bricks one upon another in which bricks there are also diagonal slits, openings, or
apertures C, so that when cold air passses underneath the fire and enters the
chamber B, the said air becomes heated, and when passing through the slits C the
heat becomes intensified so that when the hot air impinges against the fuel at
the back of the fire, it hastens on the combustion of fuel and burns the smoke.
Instead of the fire back being built up of separate bricks as shewn in the drawing,
it may be composed of one large slab or brick but this will be arranged to suit
purchasers.
By using diagonal apertures as shewn at C the fire will burn more quickly than
is the case where the fire back is one dead surface which is usually the case.

page_text: 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 :-
The construction of fire backs having a chamber B and diagonal cavities C,
arranged and constructed in the manner shewn and for purposes set forth.
Dated this 3rd day of January 1893.
