PROVISIONAL SPECIFICATION.
Improvements in or connected with Domestic Fire-places
or Grates.
I, WILLIAM HENRY HILL, of No. 34 David Street, Whytehouse Grounds,
Kirkcaldy, in the County of Fife, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in or connected with domestic fire-places
or grates and has for its object to effect more perfect combustion than heretofore,
and thereby economise fuel and lessen the escape of smoke.
For this purpose, instead of forming the bottom bars of the grate with a
generally plane surface as heretofore I shape such bars in the form of a dome
rising upon all sides to the centre which is of a curved shape so as to form a
hollow in the centre of the fire, and thus afford a large surface for the admission of
air thereto, thereby promoting the combustion of the fuel, more or less consuming
the smoke emanating therefrom and consequently giving off greater heat with a
less consumption of fuel than heretofore.
This improved grate bottom can be placed in position in the manufacture of the
stove or the original grate bottom may be removed and my improved grate bottom
fixed in position in lieu thereof.
In lieu of forming the bottom bars of the grate itself in the manner hereinbefore
described, I sometimes form a separate dome shaped false bottom in a suitable
manner to be supported by such bottom bars and I thus render my invention easily
applicable to existing grates without alteration thereof.
It will be understood that my invention is applicable to the grates of domestic
fire-places, such as register stoves and kitchen ranges, whilst it is also suitable for
employment with the grates of hot plates.

COMPLETE SPECIFICATION.
Improvements in or connected with Domestic Fire-places
or Grates.
I, WILLIAM HENRY HILL, of No. 34, David Street, Whytehouse Grounds,
Kirkcaldy, in the County of Fife, Engineer, 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 :-
My said invention relates to improvements in or connected with domestic fire-
places or grates and has for its object to effect more perfect combustion than
heretofore, and thereby economise fuel and lessen the escape of smoke.
For this purpose, instead of forming the bottom bars of the grate with a
generally plane surface as heretofore, I shape such bars in the form of a dome
rising upon all sides to the centre which is of a curved shape, so as to form a
hollow in the centre of the fire, and thus afford a large surface for the admission
of air thereto, thereby promoting the combustion of the fuel, more or less consuming
the smoke emanating therefrom and consequently giving off greater heat with a
less consumption of fuel than heretofore.
This improved grate bottom can be placed in position in the manufacture of the
stove or the original grate bottom may be removed and my improved grate bottom
fixed in position in lieu thereof.
In lieu of forming the bottom bars of the grate itself in the manner hereinbefore

page_text: described, I sometime form a separate dome shaped false bottom in a suitable
manner to be supported by such bottom bars and I thus render my invention easily
applicable to existing grates without alteration thereof.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1. is a front elevation of a domestic fire place or grate formed with a
bottom constructed according to my invention.
Figure 2. is a plan thereof.
Figure 3. is a vertical transverse section thereof taken on the line 1-1. of
Figure 1., and,
Figures 4, and 5, are respectively front and end elevations of a false grate
bottom.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1., 2. and 3. a. represents the back of the fire place or
grate, a' represents the sides or cheeks, b. represents the front bars and c. represents
the bottom bars thereof.
The bottom bars c. of the grate instead of being formed with a generally plane
surface as heretofore are shaped in the form of a dome rising from all sides to the
centre which is of a curved shape so as to form a hollow in the centre of the fire
and thus afford a large area of surface for the admission of air thereto, thereby
promoting the combustion of the fuel more or less consuming the smoke emanating
therefrom and consequently giving off greater heat with a less consumption of fuel
than heretofore.
In the example hereinbefore given, the grate bottom c. is assumed to have been
placed in position during the manufacture of the stove or to have been applied to
an existing stove after the removal of the original bottom.
In the example given at Figures 4. and 5. in lieu of forming the bottom bars of
the grate itself in the manner herein before described such bars are formed with a
plane surface as heretofore whilst the dome is formed as a separate false bottom c*
of a suitable shape to fit into an existing grate and. provided with feet c*¹ to rest
upon the bottom bars, and the invention is thus rendered easily applicable to
existing grates or stoves without alteration thereof.
It will be understood that my invention is applicable not only to the grates of
fire places such as register stoves but also to kitchen ranges and the grates of hot
plates.
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 :-
1. In a domestic fire place or grate, forming the bottom bars in the shape of a
dome rising upon all sides to the centre, substantially as herein shown and described
and for the purpose stated.
2. A bottom for domestic fire places or grates formed in the shape of a dome
rising upon all sides to the centre, substantially as herein shown and described and
for the purpose stated.
3. A false bottom for domestic fire places or grates formed in the shape of a
dome rising upon all sides to the centre thereof and adapted to rest upon the
ordinary grate bars, substantially as herein shown and described and for the purpose
stated.
