Year: 1867

page_text: PROVISIONAL SPECIFICATION left by John Allcock Jones and Richard
Howson at the Office of the Commissioners of Patents, with their
Petition, on the 26th January 1867.
We, JOHN ALLCOCK JONES, Engineer, and RICHARD Howson, Engineer,
both of Middlesbrough-on-Tees, in the County of York, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PUDDLING AND OTHER.
FURNACES FOR MELTING, BOILING, OR HEATING IRON," to be as follows:-
It relates to puddling and other furnaces employed for melting, boiling, or
heating iron, and its object is the saving of fuel by obtaining a better com-
bustion of the gases arising therefrom and the prevention of smoke. In
ordinary furnaces of this description the fire-place and the melting or heating
bearth are connected together with only a narrow bridge.
Our Invention consists, firstly, in separating the hearth from the fire-place
by means of a throat or space which forms a combustion chamber.
Secondly, in introducing into the aforesaid combustion chamber air which
bas been previously heated by passing through pipes or channels placed in the
"uptake" of the chimney or in flues having communication with the chimney.
Thirdly, in placing a damper in or about the aforesaid combustion chamber
between the fire-place and the heating hearth, to be used instead of or in
conjunction with the ordinary damper. An outside damper may also be used
to the ash-pit to regulate the admission of air to the fire-grate, which damper
may likewise be used alone or in conjunction with either or with both of the
other dampers.
