IMPROVEMENTS IN ROLLING-MILLS
Year: 1879

page_text: LETTERS PATENT to James Morgan While, of Sheffield, in the County of York,
for the Invention of "IMPROVEMENTS IN ROLLING-MILLS."
Sealed the 3rd October 1879, and dated the 5th April 1879.
PROVISIONAL SPECIFICATION left by the said James Morgan While at the
Office of the Commissioners of Patents on the 5th April 1879.
JAMES MORGAN WHILE, of Sheffield, in the County of York.
IN ROLLING MILLS."
"IMPROVEMENTS
This Invention relates to improvements in mills for rolling iron and steel (et
cetera), and consists in the employment of a third roll set at right angles to the
pair of rolls ordinarily employed, and acting simultaneously therewith.
In carrying this Invention into effect, I place the extra roll between the top and
bottom ordinary rolls, and in or on the housing which carries the ordinary rolls,
the said extra roll having its axis at right angles to the pair of rolls ordinarily
used. The extra roll can be of such a form as to produce any desired shape of one
side of the material which is being simultaneously shaped on the remaining three
sides by the pair of rolls of ordinary construction and working. In an ordinary
mill the extra roll will be placed on or in the side of the housing, or on a bracket
or other suitable support, and will either have independent motion, or will be
driven by any ordinary gearing. The extra roll can be placed and work either-in
fixed bearings or moveable bearings, and can be moved inwards and outwards by a
screw or wedge motion or otherwise, so as to regulate the action of the said extra
roll on the material under operation by the pair of rolls and the said extra roll. As
a modification of the above described means of carrying into effect my Invention,
the said extra roll can be placed in bearings on the end of a lever, so that by
suitable mechanism of ordinary construction an intermittent action of the said
extra roll on the material can be obtained.
By this Invention I can roll "sections" of iron and steel which cannot be pro-
duced by ordinary rolling-mills.

"IMPROVEMENTS
This Invention relates to improvements in mills for rolling various sections of
iron and steel (et cetera), and consists in the employment of a third roll of circular
eccentric or irregular form set at right angles to the pair of rolls ordinarily
employed, and acting simultaneously therewith.
In carrying this Invention into effect, I place an extra roll in or on one of the
housings which carry the ordinary rolls, the said extra roll having its axle or axis
at right angles to the pair or set of rolls ordinarily used.
The extra roll can be of such a form as to produce any desired shape on the side
of the material which is being operated upon simultaneously by the ordinary pair
of rolls.
In an ordinary rolling mill the extra roll will be placed on or in the side of the
housing on a bracket or other suitable support, and will either have independent
motion, or will be driven by any suitable arrangement of ordinary gearing from
the first motion shaft of the rolls.
In the accompanying two Sheets of Drawings, Figures 1, 2, and 3, illustrate my
improved rolling mill. Figure 1 is a front view in elevation; Figure 2 is a view
in elevation of the housing with my improvements applied thereto, the rolls being
shewn in section and the view as taken through and from the dotted line Y, Z,
(Figure 1); Figure 3 is a sectional plan of the aforesaid housing as taken through
the dotted line W, X, (Figure 2), showing my improvements in plan, the ordinary
roll not being shewn. A, A, are the housings; B, B, the ordinary rolls; C, the
extra roll; D, the axle of the said roll C; E, E, are plates securing the roll C in
position; F is a bracket or stay carrying the extra roll C.
In using my improved mill, the material is passed through the rolls B, B, Figure 1;
firstly, through the gate 1; secondly, through the gate 2; thirdly, through the
gate 3; fourthly, through the gate 4; and lastly, through the gate 5, in which last
operation the roll C grooves or indents the head of the rail as shown.
Having now described and particularly ascertained the nature of my said In-
vention, and the manner in which the same is or may be used or carried into effect,
I would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is,―
Improvements in rolling mills as hereinbefore specified and described and illus-
trated by the accompanying two Sheets of Drawings.
In witness whereof, I, the said James Morgan While, have hereunto set my
hand and seal, this Second day of October, in the year of our Lord One
thousand eight hundred and seventy nine.
JAMES MORGAN WHILE. (L.S.)
