Improvements in Converters.
I, TOUSSAINT LEVOZ of Stenay, France, Engineer, do hereby declare the nature
of this invention to be as follows:-
In the converter of this invention the air is blown therein through nozzles
slanting downwards from the outside so as 'to be at an angle to the floor of the
converter and to deliver at only about 4 or 5 centimetres underneath the surface
of the crude iron bath. Outside the converter and the passages or pipes leading to
the air nozzles-which are arranged over a small area only of the converter-is
placed a socket or casing into which is poured the decarbonised iron for the bath,
this being done when the converter is inclined and then also the additions to bo
made to the decarbonised iron may be introduced through an orifice in the converter
above the pocket or casing. By arranging the nozzles over a small area and
inclining the same the air has a greatly increased effect for the combustion of the
fuel and therewith also immediately induces a high temperature. The converter
serves for the treatment of larger or smaller quantities of crude iron in the manner
that the nozzles will always deliver air at the same distance underneath the surface
of the bath. This is accomplished by inclining the converter on its trunnions to
the one side or the other and therewith also the nozzles which deliver air at one
side only and over a small area of the converter.
Dated this 14th day of October 1896.

Improvements in Converters.
I, TOUSSAINT LEVOZ, of Stenay, France, 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 the converter of this invention of which Fig. 1 is a vertical section, Fig. 2 is
a front elevation, and Figs. 3 and 4 are horizontal sections on the lines 3-3, 4-4
of Fig. 1, the air is blown therein through nozzles N slanting downwards from the
outside so as to be at an angle to the floor of the converter and to deliver at only
about 4 or 5 centimetres underneath the surface of the crude iron bath. Beyond
the converting part into which open the air nozzles which are arranged over only a
small area of the converter, is formed a pocket P into which the decarbonised iron
is poured when the converter is inclined, and then also the additions to be made to
[Price 8d1

page_text: the decarbonised iron may be introduced. T is an opening for removal of scoria
and T is an orifice above the pocket P through which the metal can be poured.
By arranging the nozzles N over a small area and inclining them downwardly and
tangentially the air has a greatly increased effect for the combustion of the carbon
immediately producing a high temperature.
The converter may serve for the treatinent of larger or smaller quantities of crude
iron, the nozzles being always made to deliver air at the same distance below the
surface of the bath by inclining the converter on its trunnions.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A converter having the form and arrangement of tuyeres, described with
reference to the accompanying drawings.
