Year: 1832

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His present most Excellent Majesty King William the Fourth
did, by His Royal Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Twenty-second day of June, in the second
year of His reign, give and grant unto EDWARD GARSED, of Homerton,
in the Parish of Saint John, Hackney, in the County of Middlesex,
Gentleman, and ALFRED. ROBINSON, of Mile End, in the Parish of Saint
Dunstan, Stepney, in the said County, Merchant, His especial license,
sole privilege and authority, that they, the said Edward Garsed and Alfred
Robinson, their heirs, administrators, and assigns, and no other, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, their Invention of "CERTAIN IMPROVEMENTS IN
APPARATUS FOR HEATING, WARMING, AND VENTILATING DRYING HOUSES, ROOMS,
BUILDINGS, SHIPS, AND MINES;" in which said Letters Patent there is contained
a proviso obliging the said Edward Garsed and Alfred Robinson, or one of
them, to prepare an instrument in writing, containing a full and clear descrip-
tion of the nature of their said Invention, and the manner in which the same
is performed, and under their or his hand and seal, to cause the same to be
inrolled in His Majesty's High Court of Chancery within six calendar months

page_text: next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereto had, will more fully and at
large appear, and in default of which all such rights, liberties, and privileges
shall utterly cease, determine, and become void.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Alfred Robinson, do hereby declare and ascertain the nature of our said Inven-
tion, and the manner in which the same is to be performed, by the following
description thereof; reference -being-had to the Drawing hereto annexed, and
the figures and letters thereon marked (that is to say) :-
Our Improvements in Apparatus for Heating, Warming, and Ventilating
Drying Houses, Rooms, Buildings, Ships, and Mines, consist in the peculiar
construction of a stove or furnace with air passages, by which we are enabled
to obtain a very rapid circulation of air, heated to any degree of temperature
that may be desired, for the warming of apartments or the drying of goods.
This apparatus is formed by the arrangement of several series of hollow
tubes, through the interior of which the atmospheric air is allowed to pass
while the external surfaces of the said tubes are acted upon by the flames and
heated vapours of the furnace and flues by which they are surrounded.
The accompanying Drawing shows the furnace or stove with its air tubes, in
several views.
Figure 1 is a front elevation of the stove, having. two fire doors closing the
mouths of the fireplaces:
Figure 2. is a longitudinal section of the interior of the stove; supposing the
front part of Figure 1 to be removed, in which four ranges of; tubes a, c, d,
are seen, each range consisting of a series of tubes placed side by side in a
horizontal direction.
... Si
Figure 3 is a horizontal view of the stove, supposing the top to be removed,
and the upper range of tubes d, d, d, to be exposed to view, and also a small
part of the second range of tubes, c, c..
Figure 4, is a section of the stove taken transversely, in which all the tubes
composing the several ranges are seen, and the zig-zag direction of the flue
leading from the furnaces formed by the positions of the tubes.
:...
The distinct tubes (which are of cast iron) have a block formed at their
ends, and these are piled upon each other in the way shewn in Figures 2 and 4.
Fire bricks or bars of iron might be introduced between the blocks of each
range, for the purpose of increasing the capacity of the flues, if desired.
These tubes are hollow, as seen at Figure 4, and are open at each end for the
free passage of atmospheric air. The air to be heated may be conducted, by

page_text: any convenient means, to one end of each tube, and may be allowed to discharge
itself from the reverse end of the tube into a hot-air chamber, which may have
pipes leading to the place intended to be warmed; or conducting channels may
be formed, as at. e, Figure 2, leading from the open atmosphere, which may
supply the boxes f and 9' with cold atmospheric air; from these boxes the air
will pass into the tubes, as shewn by the arrows, and having become heated
in its progress through the tubes by the heat of the furnace and flues surround-
ing them; the air passes out at the opposite ends of the tubes, as shewn by the
arrows, into the appartment in which the stove is erected.; In the event of its
being found most convenient to erect the stove near the middle of the building,
it will be desirable to drive the heated air towards both ends, for which purpose
we place the two air boxes f and gat opposite sides of the stove, each to
supply a portion, of the tubes with air, as shewn in the horizontal view,
Figure 3, which causes the air to pass from one half of the tubes towards the
right-hand end of the building, and from the other half of the tubes toward
the left hand. The front and back plates of the stoves are secured together by
bolts and nuts, as at h, h, h, h.
But we do not confine ourselves to this particular mode of constructing the
stove, as it may be formed of fire brick instead of iron. Neither do we confine
ourselves to the number of tubes employed in each range, nor to their dimen-
sions, nor to the number of ranges.of tubes constituting the entire stove, nor to
the thickness or quality of the materials of which it may be found convenient
to make the tubes, though we prefer to have those tubes of greatest substance
which are nearest to the fire. But we claim the arrangement of hollow tubes,
open at both ends, placed in horizontal series within a furnace or stove, on the
external surfaces of which tubes the flames and heated vapours act for the
purpose of creating a rarifaction within, by which a rapid current of atmospheric
air is carried on and heated in its progress, and discharged at a high degree of
temperature.
It is scarcely necessary to say that the means by which we regulate the
degree of temperature of the air emitted from the tubes is by increasing or
diminishing the apperture of the chimney of the furnace, which is done by a
damper as usual.
In witness whereof, I, the said Alfred Robinson, have hereunto set my
hand and seal, this Seventeenth day of December, in the year of
our Lord One thousand eight hundred and thirty-two.
ALFRED ROBINSON. (L.S.)

page_text: AND BE IT REMEMBERED, that on the Seventeenth day of December,
in the third year of the reign of His present Majesty King William the Fourth,
the said Alfred Robinson came before our Lord the King in His Chancery,
