Improved Method and Apparatus for the Manufacture of Rolled
Rails, Girders, Bars, and other Rolled Objects.
I, TOUSSAINT BICHEROUX of Dusseldorf, Germany, Smelting Works Proprietor,
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 :-
My invention relates to a method of rolling rails, beams, bars and other rolled
objects described in the Specification to my Patent No. 14214 of 1891 wherein
such objects were first rolled with a groove on one side, after which they were
rolled out to the required size and configuration, during which process the said
groove became flattened together, and lastly the groove was opened out and the
sides thereof flattened down so as to form flanges.
According to my present improvements such opening out and flattening down of
the flanges is facilitated by preventing the sides of the groove from being flattened
together while the rail or other object is being rolled to the required configuration,
this being effected by providing in the rolling mill angular rollers between the
rolls, such as are shewn at bou the accompanying drawing, these rollers being of
such angular form that when the rail or other object e is being passed through the
shaping rolls a the roller will fit into the groove thereof and will prevent it from
being flattened together. These rollers a are provided for those grooves of the rolls
in which, in the process described in my said Specification, the said groove of the
object was flattened together, and also for those grooves through which the object
was passed after the groove had been flattened together.
I am aware that lateral rolls have been employed in rolling mills in conjunction
with horizontal rolls, for the purpose of forming lateral grooves in the object
rolled, but the application of the above described rollers are essentially different
from these, as they do not effect any rolling operation, but only serve to maintain
the configuration of a groove already formed.
In carrying out the present invention it is advantageous to obviate the necessity
for rolling the groove in the blank for the rail or other object in the first
instance, by employing cast metal blanks in which the groove is formed already in
the casting.
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:-
1. In the manufacture of rails, girders and other objects according to the method
set forth in the Specification to Patent No. 14214º¹, preventing the sides of the
groove formed in the blank from being flattened together during the subsequent
rolling by supporting the sides of the groove against such flattening by means of
angular rollers introduced between the grooves of the rolls, whereby the subsequent
opening out of the groove is facilitated, substantially as described.
2. In the method of rolling rails, girders and the like referred to in the
preceding claim, the use of cast metal blanks in which the necessary grooves are
formed in the casting, in order to obviate the necessity of forming such grooves by
rolling substantially as described.
