page_text: LETTERS PATENT to Charles James Henderson of N° 6 Drumsheugh Gardens
Edinburgh for an Invention of ABSTRACTING HEAT IN LARGER QUANTITIES
FROM STOVES AND OTHER HEATING APPARATUS, BY PASSING A CONFINED
CURRENT OF AIR OVER THE HOT SURFACES, AND FOR CONSTRUCTING AN
APPARATUS TO EFFECT THIS.
PROVISIONAL SPECIFICATION left by the said Charles James Henderson
at the Office of the Commissioners of Patents on the 21st June 1883.
CHARLES JAMES HENDERSON of N° 6 Drumsheugh Gardens Edinburgh
ABSTRACTING HEAT IN LARGER QUANTITIES FROM STOVES AND OTHER HEATING
APPARATUS BY PASSING A CONFINED CURRENT OF AIR OVER THE HOT Surfaces,
AND FOR CONSTRUCTING AN APPARATUS TO EFFECT THIS.
The chief object of the Patent is to bring into practical operation the known
law, of the effect of a Current of Air passing over a hot body, in abstracting a
larger portion of the heat of the body and applying this principle to obtaining a
greater portion of heat from Stoves of any kind; or other heating apparatus
In order to induce the Current of Air, the stove or other Apparatus, to be
enclosed within a few inches, by a covering of sheet Brass, Tin, or other polished
Metal, (excepting the front of the Stove or Apparatus) The front, or any Con-
venient part, to have openings made by which the cold air may enter the spaces,
between the Iron of the Stove or Apparatus, and the said Covering, such Current
after passing over the Metals, and absorbing their heat to escape at any Convenient
part of the said Covering, to where it is Wanted.
In connection with the Stove, or other heating Apparatus, when moro heat is
required, a Fan Blower to be placed, so as to increase the Current of Air (preferably
from Outside directly.) and in such case owing to the Vacuum produced, the air
may be filtered, by being made to pass through a Screen of Cotton Wool or
otherwise.

CHARLES JAMES HENDERSON of 6 Drumsheugh Gardens Edinburgh "ABSTRACTING
_HEAT_IN_LARGER QUANTITIES FROM STOVES OR OTHER HEATING APPARATUS BY
PASSING A CONFINED CURRENT OF AIR OVER THE HOT SURFACES-AND-FOR-CON--
STRUCTING AN APPARATUS TO EFFECT THIS
"
The chief object of the Patent is to bring into practical operation the known
law of the effect of a current of air, passing over a hot body, in abstracting a
larger portion of the heat of the body, and applying this principle to obtaining a
greater portion of heat from stoves of any kind, or other heating apparatus.
In order to induce the current of air, the stove or other apparatus to be enclosed,
within a few inches, by a covering of sheet brass, Tin or other polished metal
(excepting the front of the stove or apparatus) the front or any other convenient
part to have openings inade by which the cold air may enter the spaces between
the iron or other material of the stove or apparatus and the said covering such
current, after passing over the metals and absorbing their heat to escape at any
convenient part of the said covering to where it is wanted
In connection with the stove or other heating apparatus when more-heat is
required a Fanblower or Fan Exhaust to be placed, so as to increase the current of
air preferably from outside directly-and in such case owing to the vacuum
produced, the air may be filtered by being made to pass through a screen of cotton
wool or otherwise.
Having thus particularly described the nature and object of my said invention,
-I declare that what I claim is :-
1. The application of the principle of abstracting heat in larger quantities from
stoves and other heating apparatus by passing a contined current of air over the hot
surfaces substantially in the manner hereinbefore described.
In witness whereof I the said Charles James Henderson have hereunto set my
hand and seal this thirty first day of October in the year of our Lord One thousand
eight hundred and eighty three.
