I HENRY SCHALLEHN of Gresham House Old Broad Street in the City of
London Gentleman do hereby declare the nature of this invention to be as follows:-
The object of my invention is chiefly so to fit and arrange and construct domestic
fire places that the smoke or the greater part thereof arising from the fire shall be
consumed.
To carry out this object 1 make at the back of the grate a chamber extending
preferably right across the grate and broader or deeper at its lower part than at its
upper part and the walls of this chamber may be made of metal fire clay or other
suitable material. On the bottom of this chamber which is open is hinged a plate to
act as a door and regulate the admission of air to the chamber and preferably
horizontally across the chamber are a series of baffle plates whereby the air so
admitted is caused to travel backwards and forwards in the chamber and thus get
heated by the fire in the grate in front of the same before the air passes out of the
chamber through a narrow somewhat horizontal opening near the closed top of the
same into the smoke arising from the fire which is therefore consumed by this heated
air. A suitable handle is fitted to the door whereby the amount of air so admitted
is regulated.

I HENRY SCHALLEHN of Gresham House Old Broad Street in the City of
London Gentleman 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 :-
The object of this my invention is so to fit and arrange and construct domestic
fire places that the smoke that arises from the fire in the grate or the greater part
thereof shall be consumed.
In the accompanying drawings Figure 1 is a front elevation of a domestic fire
place fitted with my apparatus Figure 2 is an elevation of the apparatus with the
front thereof removed and Figure 3 is a vertical transverse section of the apparatus
these two Figures being on an enlarged scale.
In or at the back of the grate of which A are the front bars I make a chamber B
extending preferably right across the grate and broader or deeper at its lower part
than at its upper part as shewn in Figure 3 and the walls D and E of this chamber B
may be made of metal fire clay or other suitable material and when made of metal as
is perhaps preferable the front wall D can very conveniently be protected from the
fire in the grate by a face of fire brick fire clay or other similar material as shewn in
the drawing. The top and the sides of the chamber B are closed and on the bottom
thereof which is open and which is at or a little below the level of the bottom bars
of the grate is hinged on the rear wall E a plate F by which the bottom of the
chamber B can be closed when desired and this plate F can be governed and actuated
by any suitable handle or otherwise. Across the chamber B and secured to both the
walls D and E thereof are fitted a series of baffle plates H arranged in any convenient
manner preferably as is shewn in Figure 2 and in the front wall D near the top of
the chamber B is made the long narrow and preferably bowed opening K situate the
desired distance above the fuel that is placed in the grate.
When therefore the fire in the grate is lighted the air entering the bottom of the
chamber B is caused by the baffle plates H to travel backwards and forwards therein
and thus the air is highly heated before it passes out through the opening K into the
smoke that arises from the fire whereby this smoke or the greater part thereof is
consumed as is desired. To heat the air that passes up and through the chamber B
still more intensely and thus still further ensure the consumption of the smoke I can
very conveniently when the walls of this chamber B are made of metal form a
number of holes L in the front wall D to allow the heat of the face of fire brick or
other material freely to pass into the chamber B. The amount of air that so enters
and passes through the chamber B can be regulated by the plate F.
I consider that the methods and details of construction of this apparatus and the
forms of the several parts of the same as shewn in the drawings are very suitable
and convenient but I do in no wise limit myself thereto for this my apparatus and all
the several parts thereof may be so formed and constructed as may be expedient or

page_text: desirable in each particular case having regard to the fire place in which and
the grate with which the same is to be used as also to the other surrounding
circumstances.
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
In a domestic fire place the combination with the grate of the chamber B containing
the baffle plates H and formed with the opening K. and fitted with the hinged plate
substantially as and for the purpose hereinbefore described and declared.
