IMPROVEMENTS IN HEATING AND VEN- TILATING
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
GILLOTT, of Great Saffron Hill, in the County of Middlesex, Cutler, 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 Twenty-sixth day of February, in the fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Benjamin Gillott, Her especial licence, full power, sole privilege and
authority, that I, the said Benjamin Gillott, my exors, adiñors, and assigns, or
such others as I, the said Benjamin Gillott, my exors, adiñors, 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 HEATING AND VEN-
TILATING;" in which said Letters Patent is contained a proviso that I, the
said Benjamin Gillott, shall cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, 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, I, the said
Benjamin Gillott, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof (that is to say):-
The heating and ventilating apparatus is made, as far as regards the fire-
place, the same as an ordinary hot-air stove, over which is placed a boiler,
which may be made of copper, iron, or any other suitable metal, or earthen-
ware, or glass, containing tubes which are surrounded by water. The tubes
may be made of any shape or size, and placed in any position. Over the
boiler is placed a cover or lid with a small opening at the top for the supply of
water. A fan or blower is placed so that the neck of the box which contains
it terminates against or opposite the open spaces caused by the tubes in the
boiler, and is set in motion by a wheel turned by a crank handle, such wheel
giving motion by means of a strap or band to a pulley fixed on the spindle to
which the fan or blower is fastened. The air is thus thrown, driven, or drawn
through the open spaces, and gets hot in its passage to the opposite side of the
boiler, where a pipe may be placed to receive and convey it to any place or
distance required. The air thus heated by passing through boiling water is
more particularly intended for respiration, though applicable to all purposes
requiring heat of moderate temperature perfectly pure. When the apparatus
is made for commercial purposes, where heat only is required, independent of
its quality, no water is used, but a cockle or number of metal tubes instead
of a boiler, thereby allowing greater heat to be obtained, though not of equal
'purity, but still very little deteriorated, in consequence of the rapidity with which
it is forced or drawn through the apparatus by the fans or blowers; or the fire-
place may be constructed under the fan or blower box by making the said box
double, and having an opening at the bottom for the entrance of the fire
between the two cases, which will also form the flue for carrying off the
smoke. A boiler or cockle may be placed in the neck of the box to preserve
and regulate the heat, or the box itself may be used as the boiler if preferred.
The fans or blowers are constructed in the usual manner, similar to those used
in foundries, videlicet: anumber of pieces of wood, iron, or any other suitable
material, of equal size, is fastened on a spindle, and placed in a box open at the
sides or any other part most convenient, and caused to revolve by a wheel,
pulley, and strap, or any and every other power or means, as steam, horse,
wind or draft or manual labor, &c., &c., &c. The fans or blowers may be
placed in any position, vertical, horizontal, or oblique, as may be found most
desirable or convenient. They may also be placed at either side, at the top or
bottom of the apparatus, or at any distance from it found most useful or
convenient for room, &c. They may be also placed so as to draw the air
through the apparatus with the same effect as forcing it through. The pipes

page_text: for conveying the heated air to or from the apparatus may be constructed of
any metal, earthenware, glass, wood, or any other suitable material. The fire-
place is composed of iron and fire brick or fire clay, and the frame, sides, &c.
of the apparatus is made of iron or any other metal, or stout earthenware; the
wheel and pulley may be of iron, wood, brass, or any other material. The
fan or blower box may be made of wood, iron, brass, copper, zinc, or any other
suitable material. When the apparatus is intended as a permanent crection,
a great part of it can be constructed of brickwork, and the cockle or fire-
place built in, similar to the setting of an ordinary copper, and the fans or
blowers added thereto in any manner found most desirable or convenient.
Having thus described the nature of my Invention, and the manner of
performing, I would have it understood that I do not claim any of the separate
parts, nor do I confine myself to the precise details herein shewn, so long as
the character of the Invention be retained; but what I claim is, the mode of
heating and ventilating apartments, buildings, and places, by forcing air
through a heating medium, and thence into the place to be heated and
ventilated by means of a fan or blower, as herein described.
In witness whereof, I, the said Benjamin Gillott, have hereunto set my
hand and seal, this Twenty-sixth day of August, in the year of our
Lord One thousand eight hundred and forty-two.
BENJAMIN (L.S.) GILLOT.
AND BE IT REMEMBERED, that on the Twenty-sixth day of August,
in the year of our Lord 1842, the aforesaid Benjamin Gillott came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute made for that purpose.
Inrolled the Twenty-sixth day of August, in the year of our Lord One
thousand eight hundred and forty-two.
