I GEORGE FREDERICK REDFERN of the General Patent Office, No. 4 South Street,
Finsbury, in the county of Middlesex, Patent Agent; do hereby declare the nature of
this invention to be as follows:-
1
This invention consists in an improved heating apparatus constructed of one piece of
refractory earth which is recessed and provided with a suitable grate and a safety
damper as hereinafter described.
This heating apparatus consists of a block or piece of refractory earth in which a
recess is formed; the earth used may be similar to that employed in the manufacture
of gas retorts. The apparatus inade of the required size is adapted to be fitted within
fire places such as are provided in the various rooms of a building. The said block or
piece is subjected to an intense heat when being baked so as to withstand the action of
fire and by its use the three cast iron plates which have hitherto been used as a
covering for the sides and the back of a fire place are dispensed with. By means of a
contracted portion arranged at its upper part and serving to facilitate the escape of
smoke proceeding from a cast iron grate arranged at its base the heat developed by the
fuel whatever may be the kind used in the said recess is concentrated and such heat is
subsequently distributed within the room.
A safety damper of strong sheet iron is provided which can be easily manipulated
and arranged to slide through the external portion of the tube or chimney serving for
the escape of smoke whereby not only can the consumption of fuel be regulated but
should a fire occur in the chimney communication between the fire place and the
outside air can be efficiently closed.
This improved apparatus possesses the advantage over all other known apparatus
of this class of effecting a great economy in fuel and of heating the room in which it
is placed even while cooling.

An Improved Heating Apparatus or Stove.
I, GEORGE FREDERICK REDFERN, of the General Patent Office No. 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent, do hereby declare the nature of
this invention (a communication from abroad by Jean Leyrat, of Ivry, in the Republic
of France,) and in what manner. the same is to be performed to be particularly described
and ascertained in and by the following statement :-
This invention consists in an improved heating apparatus constructed of one piece
of refractory earth which is recessed and provided with a suitable grate and a safety
damper as hereinafter described.
This heating apparatus consists of a block or piece of refractory earth in which a
recess is formed; the earth used may be similar to that employed in the manufacture
of gas retorts. The apparatus made of the required size is adapted to be fitted within
fire places such as are provided in the various rooms of a building.
In order to enable the invention to be fully understood I will describe the same by
reference to the accompanying drawing in which figure 1 is a front perspective view
of a heating apparatus or stove constructed according to this invention; figure 2 is a
transverse vertical section on line x, y, of figure 1, and figure 3 is a back perspective
view of the apparatus; figure 4 is a detached plan view of the damper; figure 5 is a
front perspective view of a slightly modified construction of apparatus or stove;
figure 6 is a side perspective view of the same; figure 7 is a front elevation, and
figure 8 a side elevation of a framing or covering for the outer front edges of the
apparatus.
The block or piece A which is preferably made of the form shewn in the drawing, is
subjected to an intense heat when being baked so as to withstand the action of fire and
by its use the three cast iron plates which have hitherto been used as a covering for
the sides and the back of a fire-place are dispensed with. By means of a contracted
portion a, arranged at its upper part and serving to facilitate the escape of smoke
proceeding from the cast iron grate b, arranged at its base as shewn in figures 1 and 2,
the heat developed by the fuel, whatever may be the kind used in the said recess, is
concentrated, and such heat is subsequently distributed within the room.
c, is the safety damper of strong sheet iron which can be easily manipulated and
arranged to slide through the external portion of the tube or chimney serving for the
escape of smoke whereby not only can the consumption of fuel be regulated but should
a fire occur in the chimney communication between the fire place and the outside air
can be efficiently closed.
This improved apparatus possesses the advantage over all other known apparatus of
this class of effecting a great economy in fuel and of heating the room in which it is
placed even while cooling.
The interior as well as the exterior form of the apparatus or stove illustrated in
figures 5 to 8 is the same as that shewn in figures 1 to 3 except that the contracted

page_text: part a, at the top is dispensed with and in place thereof is applied a metal tube ɗ,
which can be placed and directed to the right or left to suit the passages of existing
chimneys. In the lower part of the tube d, is an opening in which slides easily a
register or damper e. This apparatus is made removeable in order to facilitate the
sweeping of the chimney. For this purpose a framing shewn in figures 7 and 8, is
adapted to and fixed on the front of the chimney; over this framing will be placed the
usual earthenware chimney tiles or slabs; f, figure 5 is a small hole made in the lower
part of the recessed block in order to facilitate its removal.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The combination of a recessed block or piece of refractory earth with a grate b,
and a safety damper c, substantially as hereinbefore described and represented in the
accompanying drawing.
2. The improved heating apparatus or stove hereinbefore described and represented
in the accompanying drawing.
