Chancery Lane, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN ROLLING MILLS FOR ROLLING GROOVED OR CHANNEL RAILS AND
OTHER PROFILE IRON OR STEEL." A communication from abroad by the
Societé Anonyme des Mines et Usines du Nord et de l'est de la France, of
Trith-Saint-Leyer, Nord, France, an Incorporated Company.
Sealed the 6th February 1880, and dated the 8th September 1879.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at the
Office of the Commissioners of Patents on the 8th September 1879.

GROOVED OR CHANNEL RAILS AND OTHER PROFILE IRON OR STEEL." [A com-
munication from abroad by the Societé Anonyme des Mines et Usines du Nord et
de l'est de la France, of Trith-Saint-Leyer, Nord, France, an Incorporated
Company.]
The present Invention has for its object an improved construction of rolling mill,
more particularly adapted for rolling rails or other profile iron or steel requiring to
have one or more grooves or channels formed in a direction at right or other angles
to the main surfaces which receive their configuration from the ordinary rolls.
For this purpose there are fitted to the extended trunnions of the ordinary rolls
of the rolling mill outside the headstocks or framing two overhanging finishing
rolls, the configuration of which corresponds to the main surfaces of the rail or
other iron to be produced, and facing the free ends of these rolls is a vertical roll
on an axis carried in bearings on the beadstocks or on a separate frame, which roll
acts upon and imparts the desired configuration to the end surface of the rail which
is to receive the before mentioned groove or grooves, the roll having for this pur-
pose one or more projecting rings that form the said groove or grooves as the rail is
passed through.

page_text: The vertical roll is driven either by mere frictional contact with the rail passing
through or by frictional contact with the other rolls which have for this purpose
bevilled outer faces working in contact with two corresponding bevil faces on the
vertical roll, or this can be driven by bevil gearing from the top roll of the mill.
For rolling the description of rail known as the "broca" rail, which is a flanged
rail having a head with a groove or channel on one side to receive the flanges of
the wheels, the one horizontal roll has a broad circular flange projecting up to the
groove of the other horizontal roll so as to serve as abutment to the entire flange of
the rail, while the vertical roll exerts a horizontal pressure on the head thereof in
forming the groove in the head.

CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery Lane, in
the County of Middlesex. "IMPROVEMENTS IN ROLLING MILLS FOR ROLLING
GROOVED OR CHANNEL RAILS OR OTHER PROFILE IRON OR STEEL." A com-
munication from abroad by the Societe Anonyme des Mines et Usines du Nord et
de l'Est de la France, of Frith-Saint-Leyer, Nord, France, an Incorporated
Company..
The present Invention has for its object an improved construction of rolling mill,
inore particularly adapted for rolling rails or other profile iron or steel requiring to
have one or more grooves or channels formed in a direction at right or other
angles to the main surfaces which receive their configuration from the ordinary
rolls.
For this purpose there are fitted to the extended trunnions of the ordinary rolls
of the rolling mill outside the headstocks or framing two overhanging finishing
rolls, the configuration of which corresponds to the main surfaces of the rail or other
iron to be produced, and facing the free ends of these rolls is a vertical roll on an
axis carried in bearings on the headstocks or on a separate frame, which roll acts
upon and imparts the desired configuration to the end surface of the rail which is
to receive the before mentioned groove or grooves, the roll having for this purpose
one or more projecting rings that form the said groove or grooves as the rail is
passed through.
The vertical roll is driven either by mere frictional contact with the rail passing
through or by frictional contact with the other rolls, which have for this purpose
bevilled outer faces working in contact with two corresponding bevil faces on the
vertical roll, or this can be driven by bevil gearing from the top roll of the mill.
For rolling the description of rail known as the "broca" rail, which is a flanged
rail having a head with a groove or channel on one side to receive the flanges of
the wheels, the one horizontal roll has a broad circular flange projecting up to the
groove of the other horizontal roll, so as to serve as abutment to the entire flange
of the rail, while the vertical roll exerts a horizontal pressure on the head thereof
in forming the groove in the head.
The accompanying Drawing represents this Invention applied to a three-high
roller mill for shaping a grooved rail. M, M, are parts of the ordinary rolls, the
axes of which extended beyond the headstock C carry the outer rolls A and B.
On a vertical axis is mounted the roll D, which may be driven by friction or by
bevil gearing X, X, from the top roll Z. The rail or other bar being pressed between
the three rolls A, B, and D is finished to shape, which may be varied by varying
the profiles of these rolls.
Having thus described the nature of this Invention, and in what manner the
same is to be performed as communicated to me by my foreign correspondents, I
claim,-
The combination with a rolling mill of two exterior rolls on the prolonged axes
of the main rolls and of a third roll on a vertical axis, substantially as and for the
purposes herein 'set forth.
In witness whereof, I, the said Charles Denton Abel, have hereunto set my
hand and seal, this Third day of March, in the year of our Lord One
thousand eight hundred and eighty.
