I THOMAS WARNE of 260 Upper Street Islington in the County of Middlesex
Builder and Decorator do hereby declare the nature, of my invention for
IMPROVEMENTS IN OPEN STOVES OR FIRE PLACES" to be as follows:-
This invention has for its object improvements in open stoves or fire places.
In order more effectually to radiate the heat forward into the room and to
consuine the smoke I make the back of the grate to overhang the fire. I form the
back by preference of a fire lump or lumps, it curves forward as it rises from the
fire forming a projection which roofs over the fire and compels the heated products
of combustion to take a forward course before they are able to ascend to the
chimney. Over the projection there is an inclined return along which the products
pass after they have been driven forward.

page_text: I, THOMAS WARNE of 260 Upper Street, Islington in the County of Middlesex,
Builder and Decorator do hereby declare the nature of my invention for
"IMPROVEMENTS IN OPEN STOVES OR FIRE PLACES" 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 for its object improvements in open stoves or fire places.
In order to radiate the heat forward into the room and to consume smoke
I make the back of the grate as it rises from the fire basket to curve forward with
a continuous curvature so forming a projection which roofs over the fire and
compels the heated products of combustion as they sweep along its surface to take
a forward course before they are able to ascend to the chimney.
I make this back by preference, of a solid fire lump in one piece, but it may be
made in two or more pieces. The surface of the stove back over the projection
inclines back in a manner to form a fair lead to the chimney.
In order that any said Invention may be most fully understood and readily
carried into effect I will proceed to describe tho-drawings hereunto annexed.
Figure 1 is a front elevation, and Figure-2-is-a-vertical section of an open stove-
or fireplace constructed-in-accordance-with.my.invention. The back of the stove
as here shown, consists of a single fire lump; at the lower part at A where the
fuel rests in contact with the back, its surface is vertical or nearly so, and passing
upwards from this part, the surface of the back of the stove has a continuous
curvature up to a point more or less advanced in front of the fire. As represented
in the drawing the curve is continued until the surface becomes nearly horizontal,
so that a bold projection is made at B, around which the products of combustion
rising from the fire are compelled to pass as they ascend to the chimney. It will
be observed that the products of combustion reach the point B in ascending from
the fire basket by a continuous and regular flow along the curved surface of the
stove back, which, is so formed as not to present any cavity or chamber within
which eddies may occur detaining the products of combustion in their ascent; on
the contrary the products of combustion riso continuously along a surface of a
continuous curvature. This surface becomes highly heated, and by maintaining
the temperature of the combustible gases favors the consumption of smoke.
C is the inclined surface upon the upper part of the luinp; it forms the lower
side of the flue passages by which the products of combustion pass to the chimney.
It terminates at the point where the ordinary register door for closing the chimney
is provided.
The stove shown in the drawings has parallel sides but the sides in many cases
will be inclined or splayed outwards so that the fire basket is narrower at the
back than it is as measured along the front bars.
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 —
My improvement in open stoves or fire places consisting in forming the back
thereof of a fire lump or lumps so shaped that the surface rises from the fire

and then returns by an upper incline, substantially as described and represented by
the annexed Drawings.
