This invention relates to a clamping device
for the intermediate and inner cooling sections
of a blast furnace cinder notch.
The invention has among its objects the pro
vision of an improved clamp for the intermedi
ate and inner cooling sections of a blast furnace
the outer surface 24 of the latter being of a
frusto-conical con?guration similar to that of
surface 22 so that when monkey cooler 20 is thrust
inwardly of the furnace it makes a ?uid tight
connection with the outer cooler. The monkey
cooler 2i] is similarly provided with an inner
cinder notch, such sections being termed by the
art “monkey cooler” and “monkey,” respectively.
The clamping device of the present invention is
characterized by its simplicity of construction 10
surface 28 at the endv thereof inwardly of the
furnace, surface 28 likewise being of frusto-coni
cal shape to support the monkey 26 by contact
with the correspondingly shaped conical outer
and its long life in service, as well as its posi
tiveness in holding the monkey and monkey
cooler in the desired positions in the cinder notch
surface 3%} thereof and to provide a, fluid tight
connection therewith when the monkey is thrust
inwardly of ‘the furnace.
In the normal operation of the blast furnace
the bath 34 of the molten iron therein has its top
somewhat below the inner end of the outer cooler,
and the inner ends of the outer cooler, the
to avoid damage thereto.
These and further objects of the invention will
be more readily apparent in the following de
scription.
‘The invention will be more readily understood
by reference to the accompanying drawings, in

present invention for the monkey and monkey
cooler is simple and positive in action, that it
permits ready assembly and disassembly and ad

presents the thrust from the furnace shell to the
monkey and monkey cooler in a nearly direct line
in a vertical plane. Thus, the monkey and mom
key cooler may be readily removed from the fur

the inlet and outlet pipes leading thereto, merely
by the driving out of Wedges 19 and 16 from the

is flexible in that it allows vertical adjustment
of the clamp arm in its connection to the furnace
shell. Since the vertical arm of the L-shaped
clamp bar lies in the vertical plane of the axes of
the monkey and monkey cooler and is placed
symmetrically with respect to the water cooling
such thrust proceeds almost directly from the
furnace shell in a straight line.
As a result, the
