PROVISIONAL SPECIFICATION.
Improvements in Coal Savers for Regulating the Heat of Domestic
Fires and thereby Preventing Unnecessary Consumption of Fuel.
1, HENRY MACAULAY of 88 Northgate, Wakefield in the County of York, out
of business do hereby declare the nature of this invention to be as follows :-
The object of my invention is to construct apparatus for preventing the quick
combustion of fuel in open fire places, such apparatus being also applicable for
regulating the heat of the fire.
For the above purposes I provide a plate or fire-cover shaped to suit the fire
grate; this fire-cover is constructed of metal and arranged to rest on the top of the
grate and round the fireplace, or on the fuel, thus forming a cover over the fuel
and preventing or checking thereby the passage of air into or through the same,
causing a slower combustion thereof, and reducing the heat at the same time. This
cover can be removed at pleasure without in any way interfering with the general
arrangement of the fire place and may be provided with handle, loop, or equivalent
means therefor.
Any required number of openings may be provided therein through which air
and products of combustion from below it may pass.
Dated this 6th day of June 1890.

COMPLETE SPECIFICATION.
Improvements in "Coal Savers" for Regulating the Heat of Domestic
Fires and thereby Preventing Unnecessary Consumption of Fuel.
I, HENRY MACAULAY of 88 Northgate, Wakefield in the County of York,
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 my invention is to construct apparatus for preventing the quick
combustion of fuel in open fireplaces, such apparatus being also applicable for
regulating the heat of the fire.
In the accompanying drawings Figs. 1. 2. 3. 4. 5. 6 and 7 shew my improvements
in various forms.
For the above purpose I provide a plate A as shewn in the various figures
shaped to suit the fire grate, this plate A is constructed of metal and arranged to
rest on the top of the grate B and round the fireplace as shewn at Fig. 5, or on the
fuel, thus forming a cover over such fuel and preventing or checking thereby the
passage of air into or through the same, causing a slower combustion thereof, and
reducing the heat at the same time. When preferred this cover A may be
projected downwards outside the grate and down the front as shewn at Fig. 3, thus
further checking the combustion.
This cover A can be removed at pleasure without in any way interfering with
the general arrangement of the fire place.
Referring to Fig. 2, A1 are strengthing ribs underneath the plate A. Fig. 2
as well as Fig. 1 is inverted in order to shew more completely the construction.
Any required number of openings C may be provided in the plate A through
which air and products of combustion may pass.
In some cases the cover A may be hinged on the fire-place, as shewn at Fig. 5,

page_text: forming a sort of lid, or the plate A may be provided with a sliding lid A' as shewn
at Fig. 4 arranged so as to slide any distance on or off, so that by adjusting the
same the current of air rushing through the fire can be increased or reduced at
pleasure. Fig. 7 shews the cover A of a curved form, it being the same width.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The arrangement, construction and application of plate A for preventing the
quick combustion of fuel in open fire places and for regulating the heat of the fire,
substantially as herein set forth.
