page_text: I, JOSEPH GUEST, now residing in Allegheny, Pennsylvania, in the United States
of America, Inventor 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 an improvement in rolling metals; and it consists in the
combination of two or more rolls provided with a suitably shaped pass which is adapted
to separate the web of a T-rail at a point close to the flange, and at the same time to
so bend the flange, the head, and web portion of the rail as to adapt each of the two
pieces to be readily rolled by one or more passes through the rolls into any desired
form or section, all of which will be more fully described hereinafter.
The object of my invention is to provide a pair of rolls for the reworking of railroad
rails into angle irons, splice bars etc., and which both cut a rail into two pieces and at
the same time change the shape of both pieces preparatory to being passed again
through other grooves in the rolls to convert them into angle irons, or other sections.
The accompanying drawing represents a side elevation of a pair of rolls which
embody my invention.
•
A, B, represent the two rolls which are provided at one end with the two passes C, D,
which are separated from each other by the cutting edges G and R, for separating the
rail longitudinally into two parts. The flanged portion Q of the rail passes through
the groove or pass C, and at the same time that this flanged portion is being separated
from the head or top of the rail it is given a bend, as shewn. This is necessary to
permit making the cutting edge R, thick enough to give the strength required for
shearing the web of the rail close to the flange.
At the same time that the flanged portion of the rail is being bent, the web is forced
to one side of the head, and the other side of the head is thrown outward away from
the flange and reduced in thickness, while a portion of the metal in the head is forced
into the web, thickening it up somewhat. This leaves the thickness of the head and web
so nearly alike that the piece may be readily rolled into angle irons in ordinary angle
rolls, or it may be straightened or flattened out by passing through suitable grooves in
any ordinary rolls for making flats, or the piece may be finished into almost any other
.

page_text: section desired such as splice bars, curved sections; hand rails etc. etc. The grooves or
pass N, K, shew a modification of my invention designed to prepare the rail for
making T-irons from the head and web portions and angles or flats from the Hange.
In this pass the flange is bent back and cut off in the same manner as shewn in the
other groove C, but instead of moving the web to one side of the head it is kept in the
centre, and is not changed much in form, while the head is reduced in thickness
laterally and the edges and corners squared up. This leaves the head and web portions
shaped so that it can be readily finished into a T-iron in ordinary T-rolls.
The principal feature of my invention consists in cutting the web close to the flange
and bending and distributing the metal in the head and web portions of the rail. This
while greatly facilitating the further rolling of the metal into angle irons, splice
bars, etc., which may be done in the ordinary grooves used for the purpose, still it will
be evident to those skilled in the art, that the metal after going through the first pass
or grooves C, D, is in such shape that it may be readily rolled into almost any desired
section.
•
It is evident that the head of the rail to be flattened out, may be turned either way
and the web forced over to either side of the head, or the pass may be turned upside
down, or placed in any position desired in the rolls without departing from the spirit
of my invention. The form here shewn is one of the simplest and will make the
principle clearly understood.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of the two rolls provided with the two grooves C, D, which are
separated from each other by the cutters G, R, for separating the rails at the top of
the flange, the grooves being so shaped that both the flanged and the head and web
portions are changed in shape at the same time that the rail is being divided,
substantially as shewn.
2. The combination of two rolls, provided with the two grooves N, K; which are
separated from each other by the cutters, the grooves being so shaped that the flange
and head portions are changed in shape leaving the head and web in the form of a
T-iron substantially as described.
