I WILLIAM HENRY BROWN of Richmond Street, Sheffield, in the County of York
Steel Roller do hereby declare the nature of my said Invention for. IMPROVE
MENTS IN ROLLING METALS; SUCH AS RAIL ENDS, to be as follows:-
My invention relates to improvements in rolling, and more particularly in
rolling down railway rail ends, so as to utilise then for different purposes, the
object being to prevent overlapping by the thicker parts of such unequal sections,
during the process of re-rolling.
My invention consists in the peculiar arrangement of the grooves and collars of
the rolls, so that the openings for the metal or rail ends to pass through, are
brought to an oblique or angular position of about fortyfive degrees, by which
arrangement the working surfaces of the rolls are able to follow up and support
the thin parts of the metal or rail end while it is being compressed and thickened;
and to prevent the thicker parts, such as the sides of the head "overlapping" -or
forming a seam, which renders such re-rolled metal nearly.worthless.
In carrying my invention into practice to re-roll rail ends (for example)
I preferably turn at one or both ends of the pair of rolls, collars and grooves to
prevent lateral play, and I turn a diagonal or bevilled face in each roll, so that
when brought together, the space between the two faces forms the opening through
which the metal is to be passed. Que or more of these diagonal openings may be
made in each pair of rolls.
The opening so formed approximates somewhat to the configuration of the cross-
section of the rail-end, a projecting collar in the centre of each face, narrowing the
opening through which the web of the rail end passes, but leaving room for the
web to thicken by compression upon the heads. The collars which have their edges
bevilled allow the metal to leave the rolls very readily, and also support thé
underside of the heads so as to prevent overlapping. The opening for the next
pass of the metal, will vary from the first in being shorter, and, broader opposite
the web, also rather narrower in the space for the heads; the third opening has
the variation from the first in a more marked degree the central collar being nearly
obliterated, the finishing opening being simply a plain oblong, or other shape the
size of the required bar. The number of such openings to produce the finished bar
may be varied.

Steel Roller do hereby declare the nature of my invention for IMPROVEMENTS IN
ROLLING METALS, SUCH AS RAIL ENDS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
My invention is particularly applicable rolling down railway ends, so as to
utilise them for different purposes, the object being to prevent overlapping by the
thicker parts of such unequal section as rails, during the process of rolling.
It consists in the peculiar arangement of the grooves and collars of the rolls,
which is such that the openings for the metal or rail ends to pass through, are
brought to an oblique or angular position of about forty five degrees, by which
arrangement the working surfaces of the rolls are able to follow up and support
the thin parts of the metal or rail end, while it is being compressed and thickened,
and also to prevent the thicker parts such as the sides of the head "overlapping'
or forming a seam, which when it occurs causes such rerolled metal to be nearly
.worthless.
"
My Invention is illustrated in the annexed sheet of drawings which represent
a pair of Rolls constructed or turned according to my method, for rerolling rail ends
I preferably turn at one or both ends of the pair of rolls collars and grooves AA
to prevent any lateral or end movement, and I turn a diagonal or bevilled face B
in each roll, so that when brought together, the space between the two faces forms
the opening C through which the metal is to be passed.
One only, or a series of these diagonal openings may be formed in each pair of
rolls.
The opening so formed approximates somewhat to the configuration of the cross-
section of the rail-end, a projecting collar D in the centre of each face narrows or
contracts the opening through which the web of the rail end passes, but leaves
sufficient room for the web to enlarge or thicken by the compression upon the
heads.
The Collars having bevilled edges d, permit the metal to leave the rolls easily, at
the same time supporting the heads of the rail, in such a manner as to prevent
overlapping.
The opening for the next pass of the metal E, will vary from the first, in being
shorter, and also broader opposite the web, and narrower in the space for the
heads; in the third opening F, the variation from the first as before described is in
a more marked degree, the central collar, f, being nearly obliterated, while the
fourth opening G, for the finishing pass is simply a plain oblong, or other desired
shape for the finished bar.
:
I do not bind myself to the number of openings between the first and the
finishing pass, this being left to the judgment of the roller or manager.
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 rolling metals such as rail ends, the arrangement of the grooves and central
collars, of the rolls, for the purpose specified, and substantially as hereinbefore
described and illustrated.

page_text: 2. In rolls for rerolling rail ends, the diagonal grooves C, in combination with
supporting collars D, formed upon the faces B, of any angle that will permit the
free delivery of the rail,
