PROVISIONAL SPECIFICATION.
Improved Construction of Puddling and Heating Furnaces for
Iron-works.
I, JOSEPH BROOKES, 558 Leek Road, Park View, Stoke-on-Trent, Staffs,
Furnace Builder, do hereby declare the nature of this invention to be as
follows:
—
This my invention relates to a new or improved construction of puddling and
heating furnaces for iron works, the object of my said invention being to construct
such furnaces so as to render them more economical in the consumption of fuel, and
be more readily operated than the furnaces usually constructed for the same
purpose.
To carry my said invention into practice I construct such furnaces with a
hollow metallic trough around three of their sides, the lower part of each trough
when fitted in position being open so as to admit air to its interior part, the side of
Euch trough or troughs nearest to the fire having any convenient number of suitably
shaped slots or apertures formed therein so as to adinit air above the fire-bars to
the burning fuel, each fire-bar, or each bar of each section of fire-bars make
with a longitudinal groove or channel on its top side to permit fine coal or slack.
to be placed in such grooves for preventing clinkers adhering to the top sides of
such grates or bars.
The bars for the back end of such furnaces which are fitted or fixed at any
suitable inclination for conducting or directing fuel from a hopper or hoppers on
to the fire grate I make in sections, that is I cast any suitable number of such
bars together with one or more hooks or holes at one end of each of such sections,
so as to enable each section of bars to be readily fitted on to a suitable metallic
bar bearer extending from side to side of such furnaces at a suitable distance above
their fire-grate, the lower parts of the said bars or sections of bars when fitted in
position can be raised separately to a suitable height above the fire-grate bars to
enable the burning fuel of one part of the fire to be stirred or loosened without
destroying the efficiency of the remaining part of the fire and causing smoke. To
one side of the lower part of each hopper of such furnaces I fit or hinge a suitable
metallic or other flap or door for enabling the supply of fuel to be shut off or
stopped when required, especially during the stoking of the burning fuel on the
fire-grates of such furnaces.
1 would have it understood that such improvements as herein described are
applicable to the ordinarily constructed puddling and heating furnaces of
ironworks, the shape and size of each furnace remaining the same, or being
built of any suitable size of fire-brick or other suitable material or materials.

1, JOSEPH BROOKES 558 Leek Road, Park View, Stoke-on-Trent Staffs,
Furnace Builder 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 :-
This my invention has reference to a new or improved construction of puddling
und heating furnaces for iron-works, the object of my said invention being to
lessen the quantity of brickwork that is usually required in building furnaces for
paddling and heating purposes, to lessen the amount of clinkers forming on and
hering to the grates of such furunces, to lessen the consumption of fuel, to ensure
the complete combustion of fuel, to lessen the formation of smoke, and to cuable
such furnaces to be more readily operated than the furnaces nsually constructed
for such purposes.
In carrying my said invention into practice 1 construct such furnaces of any
suitable shape and size with a hollow trough or air.chambers made of or from
cast irun, fire brick or other suitable heat resisting material around their back and
sides, the lower part of each trough when fitted in position being open, or having
suitable openings or apertures formed therein so as to admit air to the interior of
such troughs or chambers, the side of such chamber or troughs nearest to the fire
having any convenient number of suitably shaped slots or apertures formed therein
so as to admit air to the burning fuel, each fire-bar, or each bar of each section of
fire-bars I make with a longitudinal groove or channel in its top surface to permit
fine coal or slack to be placed in such grooves for preventing clinkers adhering to
the top side of such bars or grates.
on to
The bars for the back end of such furnaces which are fitted or fixed at any
suitable inclination for conducting or directing fuel from a hopper or hoppers
the fire-grate I make in sections that is I cast any suitable number of such burs
together with one or more hooks or holes at one end of each of such sections, so
as to enable such section of bars to be readily fitted on to a suitable metallic bar
extending from side to side of the back end of such furnaces at a suitable distance
above their fire-grate, the lower end of the said bars or sections of bars when fitted
in position can be raised separately to a suitable height above the fire-grate to
enable the burning fuel of one part of the fire to be stirred or loosened without
destroying the efficiency of the remaining part of the fire and causing smoke.
To one side of the lower part of each hopper fitted or fixed to such furnaces
I fit or hinge a suitable metallic or other flap or door for regulating the supply of
fuel to such furnaces.
In order that my said invention may be more readily understood and explained
in detail have hereunto annexed two sheets of drawings shewing the application
of my invention to such furances, and on which drawings letters of reference are
marked on corresponding parts on all the figures alike.

in the direction shewn by arrow A.
Figure 5 is an end elevation of Figure 4 looking in the direction indicated by
arrow B.
Figure 6 is a plan view of the air chambers or troughs shewn at Figures 1
and 2.
Figure 7 is an inverted plan view of one of the air-chambers or troughs.
Figure 8 is an end elevation of one of the side air-chambers, looking in the
direction indicated by arrow H.
Figure 9 is a transverse sectional elevation of one of the air-chambers, through
the line E-Fon Figure 6, on reference to Figures 7, 8 and 9 it will be seen that
the underside of the air-chambers are open from end to end of their length.
Figure 10 is a modified transverse sectional elevation of Figure 9.
Figure 11 is a side elevation of either of the air-chambers or troughs, looking
in the direction indicated by arrows C, D, G.
Figures 12 and 13 are modified transverse sectional elevations of Figures 9 and 10,
showing slots c' through the sides of such chambers, and slots c', through the
bottom side of such air-chambers.
On these figures a represents the brickwork of such furnaces, the inclined
sections of cast-iron bars at the back end of such improved furnaces, c the cast-iron
or other chambers or other chambers or troughs fitted or fixed around the interior
of such furnace, the lower part of the openings or apertures through the side of
such chambers nearest to the fire-grated being on a level with, or a suitable
distance above the top surface of the fire-grate d. On reference to Figures 3, 4
and 5 that I have shewn the top of each bar in each section formed or cast with a
groove or channel e, in which grooves fine coal or slack can be placed to prevent
elinkers adhering to the top side or face of such bars, or such bars may be formed
without channels or grooves.
The fire-grate bars may be separate from each other as is usual, or cast or
formed in sections with grooves or channels in their top side, similar to the
bars shewn at Figures 3, 4 and 5; but without the depending part or portion f
It will be understood that fine coal, slack or other suitable fuel may be supplied
in regulated quantities to the fires of such furnaces from a suitable metallic or other
hopper, fitted or fixed to the back end of such furnaces, by opening or closing
the outlet of such hoppers by means of a suitable flap or shutter, having a
suitable crank, wheel, chain or lerer attached to one or both of the ends i of its
spindle or trunnion.
Air entering such chambers or troughs c from their underside c', and through
holes or apertures c³ will flow or pass from the interior of such chambers or troughs
through the slots into or amongst the burning fuel on the fire-grate, thus
ensuring combustion of the fuel, lessening the formation of smoke, and the
formation of clinkers on such fire-grates.
A suitable damper or slutter may be attached or fitted to each of the air-inlets
so as to regulate the quantity of air passing into the chambers e, one end of a
suitable steam conducting pipe & (which may be fitted with a suitable cock or tap)
being shewn fitted or fixed a suitable distance within the air-inlets and c so that
air only, or air mixed with steam may be inducted to the fires of such furnaces,
the openings or apertures, m being intended for the introduction of fuel to such
furnaces in addition to the fine coal or slack supplied from the hopper g.
The drawings hereunto annexed are not drawn to any particular scale being
only intended to shew the application of my invention to such puddling and
heating furnaces.
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
