I, WILLIAM COCHRANE of St Johns Chambers, Newcastle-upon-Tyne in the
County of Northumberland, Mining Engineer do hereby declare the nature of this
invention to be as follows:-
'
In constructing bogies, moulds or boxes for the reception of liquid slag from blast
furnaces and other furnaces, in particular bogies or moulds such as those described
in the Specification to my Patent No 15118 dated 17th November 1884, wherein
they are constructed with a partition, ridge or core centrally or otherwise placed,
the mould or casing and the ridge or core or one or other of them may be made of
two or more separate pieces for facility of manufacture, such separate parts being
provided with flanges by which they are bolted or otherwise fixed together, and in
order to prevent the molten slag from running through the joints of the parts,
these joints have heretofore been packed or luted with clay or other material
entailing a considerable amount of difficult labour.
My present invention has for its object to provide simple and expeditious means
of making such joints sufficiently fluid tight to prevent the egress of molten slag
through them, and it consists in forming in the meeting faces of the separate pieces
grooves in which I insert strips or bands of iron or other suitable material, so that
each such strip in extending from the groove of the one part into that of the other
part will effectually cover the joint between them so as to prevent the escape of
slag. In cases where joints of three or more separate parts meet at one point, a
strip of metal is.carried continuously through the joints in one direction, and the
strips in the joint or joints running at an angle thereto may either be made
continuous or to butt closely up against the sides of the said strip.

I, WILLIAM COCHRANE, of St John's Chambers, Newcastle-upon-Tyne in the
County of Northumberland, Mining Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
In constructing bogies, moulds or boxes for the reception of liquid slag from
blast furnaces and other furnaces, in particular bogies or moulds such as those
described in the Specification to my Patent N° 15118 dated 17th November 1884,
wherein they are constructed with a partition, ridge or core centrally or otherwise
placed, the mould or casing and the ridge or core or one or other of them may be
made of two or more separate pieces for facility of manufacture, such separate
parts being provided with flanges by which they are bolted or otherwise fixed
together, and in order to prevent the molten slag from running through the joints
of the parts, these joints have heretofore been packed or luted with clay or other
material entailing a considerable amount of difficult labour.
My present invention has for its object to provide simple and expeditious means
of making such joints sufficiently fluid tight to prevent the egress of molten slag
through them, and it consists in forming in the meeting faces of the separate pieces
grooves in which I insert strips or bands of iron or other suitable material so that
each such strip in extending from the groove of the one part into that of the other
part will effectually cover the joint between them so as to prevent the escape of
slag. In cases where joints of three or more separate parts meet at one point, a
strip of metal is carried continuously through the joints in one direction and the
strips in the joint or joints running at an angle thereto may either be made
continuous or to butt closely up against the sides of the said strip.
Fig. 1 of the accompanying drawings shews a longitudinal section of the ridge
or partition of a slag box with my invention applied thereto, Fig. 2 shews a part
end view and part cross section, Fig. 3 shews a part plan and part horizontal
section, and Fig. 4 shews a full size section of the part X where the four joints
meet.
The partition ridge or core A is here shewn constructed of four separate parts,
which are bolted together by means of flanges B. In the meeting faces of the
several parts are formed grooves in which are inserted strips of metal C, of sufficient
width to fill out the grooves of the two parts, and thus effectually cover the joint
thereof.

page_text: Having now particularly described and ascertained the nature of my said.
invention and in what manner the same is to be performed I declare that what
I claim is :-
In ridges, partitions or cores for slag boxes, constructing the meeting faces of the
several parts of the ridge, partition or core with grooves in which are inserted
strips of metal in such manner as to cover the joints, for the purpose of preventing
the escape of liquid slag through the same substantially as herein described.
Dated this 9th day of August 1886.
