IMPROVEMENTS IN MEANS FOR MANIPULATING BESSEMER CONVERTERS
Year: 1884

page_text: I ALFRED TRAPPEN, of Wetter-on-the-Ruhr in the. Kingdom of Prussia and
German Empire, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN MEANS FOR MANIPULATING BESSEMER CONVERTERS" and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This Invention relates to Bessemer-converters, and more particularly consists in
a movable or portable Bessemer-converter which is obtained by securing a converter
directly to the jib, or neck, of a crane.
The said portable converter allows of being raised and lowered, and at the same
time of being moved along the periphery of the circle described by the said jib of
the turning crane, and also of being turned on or swung around its own axis by
means of some suitable, turning device attached to the said crane. The converter
may thus be moved immediately in front of the smelting-furnace, be charged with
the molten cast iron in a direct manner, without the employment of drains or
gutters of any considerable length as now in use, and then, after the converting
process has been completed, be moved so as to pour or empty its contents directly
into the chills arranged within a proper circle.
In the accompanying Drawings
Figure 1 illustrates in elevation the construction of my said improved converter.
Figure 2 shows the same in plan when applied for use in a Bessemer-works, and
Figure 3 shows the converter in side elevation.
A indicates the movable converter secured by means of the shaft D, directly to
the jib B of the crane C, which may be raised and lowered in the usual and
well-known manner, and, at the same time, by turning on its vertical axis, allows
of moving the converter A along the circumference of the circle described by the
jib B of the said turning crane C.
The shaft D which is arranged in suitable bearings m m upon the jib B and
preferably made hollow, is provided with the worin-wheel E in gear with a
worm E¹ upon the shaft of the hand-wheel F, and thus it will be seen that by
rotating the said wheel F, the converter A may be turned on or swung around its
horizontal axis.
G. G indicate an air conduit, preferably passing through the hollow part of the
shaft D, for feeding the converter with atmospheric air, and H is a stop-valve for
regulating the flow of air into the converter.

page_text: It will be readily understood from the Drawings that by turning the crane C on
its vertical axis, the converter A may be moved immediately in front of the
smelting-furnace J, and that at the same time, by turning the shaft D by means
of the hand-wheel F, the worm E¹ and worm wheel E, the converter may be
caused to assume the position A' shown in Figure 3. From this arrangement it
will be seen that drains or gutters of any considerable length may be dispensed
with.
During the smelting process the converter is turned out of the way so as to
aasume the position A" shown in dotted lines in Figure 2.
The converter A on being charged, is moved so as to discharge the slags of the
charge into the receptacle M, and is then turned successively in line with the
chills N N, so as to empty into the latter the pure product obtained which
according to the object of the Invention is done in a direct manner without
requiring the use of a shank for the purpose.
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:
The direct connection of a Bessemer-converter with a crane of any suitable
construction, for the purpose of facilitating the charging of the said converter with
the molten cast-iron, and the emptying of the converted product from the said
converter into the chills, both the charging and emptying operations taking
place in a direct manner without the employment of any intermediate apparatus.
