AND ENDS OF PUDDLING FURNACES," to be as follows:-
This Invention bas for its object, improvements in preserving or protecting

ends of puddling furnaces are protected by applying thereto a composition or
combination of coal tar, or pitch, or asphaltum with coke, or coke dust, ashes,
or cinders, or large or small or dust of coal, which when applied to and
subjected to high temperatures will form a protective carbonaceous compound,
and prevent the otherwise injurious effects of the high temperatures on the
sides and ends of puddling furnaces.

Witton Park Ironworks, near Darlington, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of
our Lord One thousand eight hundred and sixty, in the twenty-third

time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN PROTECTING THE SIDES AND ENDS OF
PUDDLING FURNACES," upon the condition (amongst others) that we, the said
Alfred Clayton Hill and William Morgan, our executors or administrators, by
an instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office, within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Alfred Clayton Hill, on behalf of
myself and the said William Morgan, do hereby declare the nature of the
said Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention has for its object improvements in protecting the sides and
ends of puddling furnaces. For these purposes the sides and ends of puddling
furnaces are protected by applying thereto (either in a loose or compact form,)
a composition or combination of coal tar, pitch, or asphaltum with coke, or
coke dust, ashes, or cinders, or large or small or dust of coal, which when

page_text: applied to and subjected to high temperatures, will form a protective
carbonaceous compound and prevent the otherwise injurious effects of the
high temperatures on the sides and ends of puddling furnaces.
Mixtures found to be adapted for the above purpose are composed of 15%
of coal tar, and 85% of coko dust, or 8% of pitch, and 92°% of the small or
dust of coal, or culm; but we do not restrict our Invention to any particular
proportion or combination of the materials herein-before mentioned. The
mixture is placed against the sides and the ends of the puddling furnaces, and
is then covered up with hot cinder or with iron scales, or with oxides of iron
to protect it from the oxidizing effect of the atmosphere. The pig or cast
iron or metal is then charged and worked in the usual manner.
In witness whereof, I, the said Alfred Clayton Hill, have hereunto set my
hand and seal, this Tenth day of August, in the year of our Lord
One thousand eight hundred and sixty.
ALFRED CLAYTON HILL. (L.S.)
