COMPLETE SPECIFICATION.
Improvements in Meaus for Facilitating the Combustion of Fuel in
Furnaces and Fire-places.
JOSIAH HAMPTON 64 Regent Street Loughborough Leicestershire 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:
Fig. 1, sheet 1, represents a cross section of a furnace through the greatest depth
of the fire bars.
Fig. 2, sheet 1, represents a longitudinal section shewing air chamber over end of
bars.
Fig. 3, sheet 1, represents a plan of same taken a few inches above the level
of bars.
Fig. 4, sheet 1, represents a longitudinal section shewing apparatus partly over the
brick bridge.
Fig. 1, sheet 2, represents a longitudinal section shewing chamber supported by
back and transverse plates.
Fig. 1, sheet 3, represents a section from front to back of an ordinary domestic fire
grate or fire basket with my apparatus in position.
Fig. 2, sheet 3, represents front elevation of apparatus for use in domestic or open
fire places.
At the back of the furnace grate or bars or fire basket I employ an air chamber A,
constructed of one or more parts, with an open bottom, and shaped so as to suit the
furnace or grate in which it is to be employed: In the upper portion of the front of
the air chamber A are perforations E to admit air underneath and into the back of
the fire and smoke causing more perfect combustion of the fuel.
I also employ a
bevilled plate B to direct the current of air against the front of air chamber A.
In furnaces the air chamber A may be placed upon the ends of the furnace bars
(Fig. 2 sheet 1) the uncovered spaces between the bars allowing the warm air to
pass up from ash pit into the air chamber A.
The air chamber may be either wholly or partly over the bars (Fig. 2 and
Fig. sheet 1), or wholly or partly over the bridge D (Fig. 4 sheet 1) in which
latter cases I employ, in conjunction with the chamber A, a transverse plate C
with an aperture F to allow the air to pass into chamber A.
I also cut away
portions of the brick bridge D to give admission of air up to plate C.
I also employ a half round plate H, in conjunction with and bolted to the
plate C, the plate H, closing up the back of ash pit, obviates the necessity for
brick bridge D; where desired. I also employ a false bottom G with the air
chamber A at back of domestic fire grates to preserve a passage, for the air, to
chamber.
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 construction and employment of an air chamber A with perforations at
an and on at the bottom. sombined with an inner hevilled plato B transversa

page_text: plate C, and back plate H, so as to either place the chamber A wholly or partly over
the furnace bars, or wholly or partly over the brick bridge D; each part being
adjustable for renewal or otherwise as before described and shewn in the accom-
panying drawings.
Dated this 16th day of June 1890.
