page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JUCKES, of Shropshire, Gentleman, send greeting.
WHEREAS Her Present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West
minster, the Eighth day of November, in the Second year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said John
Juckes, Her especial licence, full power, sole privilege, and authority, that I,
the said John Juckes, my exors, adñiors, and assigns, or such others as I,
the said John Juckes, my exors, admors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick upon Tweed, my Invention
of IMPROVEMENTS IN STEAM-ENGINE BOILERS, AND IN APPARATUS FOR FEEDING
FURNACES AND FIRE-PLACES, AND FOR THE MORE EFFECTUAL COMBUSTION OF THE SMOKE
AND GASES ARISING THEREFROM;" in which said Letters Patent is contained
a proviso that I, the said John Juke, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, 1, the said
John Juckes, do hereby declare the nature of my Invention, and the manner

page_text: in which the same is to be performed, are fully described and ascertained in
and by the following statement thereof, reference being had to the Drawing
hereunto annexed, and to the figures and letters marked thereon, that is
to say:-
My Invention relates, first, to improvements in steam boilers and furnaces,
whereby the fuel may be fed into the furnaces in such a manner as to be acted
upon by heat previously to coming on to the fire bars of the furnaces; and
secondly, my Invention relates to so modifying or arranging other furnaces
and fire-places that they may have like improvements of the modes of feeding
fuel applied thereto; and I would here generally state that the object of
modifying steam boilers and their furnaces, as well as in respect to other
furnaces and fire-places, is to arrange the same that the fire may heat suit-
able surfaces through which the fuel is forced, that there may be a previous
heating of the fuel before it comes into the fire-place or grate; and it should
be understood, that whatever be the form in which my Invention may
appear, I make no claim to any modification or arrangement of boiler or
furnace or fire-place or stove, unless it be combined with means according
to my Invention of supplying fuel through tubes or surfaces heated by the
fire, into which the fuel is to be forced to supply the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows part of a section of a steam engine boiler arranged or modi-
fied according to my Invention. Figure 2 shows another arrangement of
boiler in section according to my Invention. The boilers themselves do not
materiallydiffer from ordinary boilers, excepting inasmuch as theyare modified
to receive the other parts of the apparatus shewn in the Drawing. Figure 3
shews another arrangement of boiler in section. In each of these Figures the
same letters indicate similar parts, and such parts are only varied in their con-
struction, in order to adapt them to the position in which they are placed, and
are connected with suitable modifications of steam boilers and of steam boiler
furnaces, aswill readily be understood on examining these Figures of the Draw-
ing, a,a,arethe fire bars of the fire-place of the furnaces. 6 is a tube through
which the fuelis fed to the furnaces. These tubes may be of any suitable material;
butI prefer that that portion or end which is acted on by the heat in thefire-place
should be of cast iron or of fire clay, in order to its lasting as long as possible;
it will be seen that the end 61 of each of these tubes must necessarily become
highly heated, and that the coal or fuel in contact with such portions of heated
surface must have a distillatory process performed thereon, for it will be
evident that the fuel will become highly heated before it receives any supply of

page_text: atmospheric air in order to support its combustion, which it will get so soon
as it has passed the end of the tube at b', and it is the capability of obtaining
this result with suitably modified steam boilers, and of steam boiler furnaces,
which constitutes my Invention. The fuel in that portion of the tube or
heated surface b, b', will have much of its properties distilled off, which
will pass into the fire-place amongst the highly heated fuel on the fire-bars
and be inflamed; and as the coked products are forced in to the fire-places
of the furnaces, such coked material or product of the fuel will become the
highly heated fire for acting on succeeding quantities of fuel.
hoppers into which the fuel is placed, having openings into the tubes or
ways. b. and d are rammers by which fresh quantities of fuel are forced
forward, which are clearly shewn in the Drawing.

Figure 4 shows a hot stove for heating apartments constructed according
to my Invention. Figures 5 and 6 show two arrangements of two open stoves
or ranges. In each of these Figures the same letters indicate similar parts
as have been before described and shewn, such parts differing only inasmuch
as they are rendered suitable for the peculiar construction of stove to which
the same are applied; but in Figure 6 the arrangement of apparatus for
forcing up the fuel is somewhat different to the other arrangements. f is an
angular scoop by which the fuel is forced up, the angular scoop f moving
on au axes at g; and there is a curved rack by which the same can be
moved by a pinion h, having a suitable handle. In this case the fire bars are so
arranged in the centre as to be drawn back when the fuel is being forced
into the fire-place, as is clearly shewn in the Drawing.
Having thus described the nature of my Invention, I would remark, that I
lay no claim to any of the parts separately which are shewn and described, nor
do I confine myself to the arrangements of steam boilers or furnaces or stoves,
as shewn, so long as the same are arranged for having the fuel applied to the
fire-places thereof according to my Invention, and as above stated. I make
no claim to any of the modifications when uncombined with such means of
supplying fuel; but what I claim is, first, the mode of arranging steam
boilers and furnaces in such manner as to have fuel fed to the fire-places
thereof through heated surfaces, which previously prepare or produce a distil
latory process on the coal before it comes into the furnace, as above explained;
and, secondly, I claim the mode of applying suitable means for heating the
fuel of furnaces and stoves in such manner that the fuel in its progress to the
fire-places thereof shall be heated or have a distillatory process performed
thereon as above described; and, lastly, I claim the mode of using of a sliding
bar or bars to fire-places, as shown at Figure 6, when combined with feeding
