The men tending the furnace did not have to handle the
rails by mean strength alone.  Edward W. KcKenna thought 
of that, as shown in his US Patents No. 522,228 and 635,577. 

Cropped View  The man tending the furnace at right did not 
have to pull each rail out of the furnace by mean strength 
alone.  The image below shows that he is attaching a clamping 
device that is hooked up to a cable:

Note also that he is standing between the conveyor rolls !

This part of the patent drawing shows
that the rails are elongated by the rolls
just enough to permit the cropping of
the battered rail ends and worn bolt holes.

This furnace detail suggests that the
patent allows for rail transport by
roller conveyor.

Even though the patent drawing shows
a mirror image of the actual McKenna
plant layout, the resemblance is quite
clear.
