PROVISIONAL SPECIFICATION left by the said James Brody Brechin
at the Office of the Commissioners of Patents, with his Petition,
on the 8th April 1874.
I, JAMES BRODY BRECHIN, of Dundee, in the County of Forfar,
North Britain, Bible Publisher, do hereby declare the nature of the said
Invention for "IMPROVED APPARATUS FOR ECONOMIsing Fuel by IncREASING THE
HEATING EFFECTS OBTAINABLE FROM ORDINARY FIRE-PLACES," to be as follows,
that is to say: :-
This Invention has for its object to economise fuel by means of
improved apparatus designed to increase the heating effects obtainable
from ordinary fire-places.

page_text: This improved apparatus acts by causing heat ordinarily wasted to be
distributed over a considerable surface of metal, which it permeates, and
from which it radiates into the room, apartment, or space to be heated.
The apparatus comprises a metallic box placed against or at a small
distance from the wall above an ordinary fire-place, and made to com-
municate with the chimney by two passages. The chimney is blocked
by a plate of metal between the two passages, so that the fire gases or
heated gaseous mixture produced by the combustion of the fuel passing
up the chimney is compelled to enter and pass through the metallic box.
The metallic box may be fitted with internal partitions to compel the :
fire gases to take a circuitous course through the box with the view of
imparting the more of their heat to it.
At the part of the apparatus where the fire gases pass out of the box
and re-enter the chimney a damper or valve is fitted for regulating the
draught and when necessary to close the chimney against down
draughts; this damper may however be placed at any other part of the
apparatus if found preferable. If preferred the box may be formed of
earthenware.
