Year: 1869

page_text: LETTERS PATENT to John Dick, of Coatbridge, in the County of
Lanark, North Britain, for the Invention of "IMPROVEMENTS IN
THE ROLLS FOR ROLLING MILLS."
Sealed the 19th November 1869, and dated the 25th May 1869.
PROVISIONAL SPECIFICATION left by the said John Dick at the
Office of the Commissioners of Patents, with his Petition, on the
25th May 1869.
I, JOHN DICK, of Coatbridge, in the County of Lanark, North Britain,
do hereby declare the nature of the said Invention of "IMPROVEMENTS
IN THE ROLLS FOR ROLLING MILLS," to be as follows, that is to say :-
This Invention, which relates to improvements in the rolls of rolling
mills for rolling iron or other metals, consists in forming such rolls
hollow in place of solid as hitherto, so that the rolls may be kept cool
by allowing water or other liquid or fluid to flow through them.

filed, by the said John Dick in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOIN
Dick, of Coatbridge, in the County of Lanark, North Britain, send
greeting.
WHEREAS er most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of May, in the year of
our Lord One thousand eight hundred and sixty-nine, in the 32nd
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Dick, Her special license that
1, the said John Dick, my executors, administrators, and assigns,
or such others as T, the said John Dick, my executors, administrators,
or assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE ROLLS FOR
ROLLING. MILLS," upon the condition (amongst others) that 1, the
said John Dick, by an instrument in writing under my hand and
scal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I. the said John Dick, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:-
My said Invention, which relates to improvements in the rolls of
rolling mills for rolling iron or other metals, consists in forming such
rolls hollow in place of solid as hitherto, so that the rolls may be kept
cool by allowing water or other liquid or fluid to flow through them.

page_text: And in order that my said Invention may be properly understood I
now proceed more particularly to set forth the system, mode, or manner
in or under which the same is or may be used or practically carried
into effect, that is to say :-
At Figure 1 on the accompanying Sheet of Drawings is shown an
end elevation of a mill for rolling iron or other materials with my
improved rolls applied thereto, and at Figure 2 is represented a front
elevation of the same. The rolls A, A', are cast hollow instead of being
made solid as formerly, and the cavity of the body is preferably of
larger diameter than that of the neck, which is again larger than the
junction picce or clutch. The rolls A, A', are supplied with water
through the pipes B, B', from a trough O placed above it. The pipes
B, B', are held in position by the bracket H fixed to the side of the
standard or framing I. The lower ends of the pipes B, B', are curved
as shown particularly at D, D', Figure 2, so as to enable them to be
carried any distance into the rolls A, A'. thereby enabling the water
to be supplied well into the body of the rolls, the curved ends D, D',
of the pipes B, B', not being fixed inside the necks of the rolls, and a
small space C, C, being left between the outside of the pipes and the
inside of the holes enables the rolls to turn freely without coming into
contact with the pipes, and these spaces C, C, also enable a certain
quantity of water to run out at the junction or clutch, thereby cooling
the bearings of the rolls. Where two or more trains of rolls are con-
nected together hollow junction shafts F, F, are employed instead of
the usual solid ones, and pipes G, G', are passed through them into the
necks of the rolls of the next train and co-axially with them, thereby
establishing a communication between two series of rolls, which enables
the water to pass from one train of rolls to that next to it. The water
having passed through all the rolls runs out at the necks of the last
train to waste. The pipes G, G', may or may not be made water-tight
within the junction shafts F, F.
Having now described the nature of my said Invention, and the
system, more, or manner in or under which the same is or may be used
or practically carried into effect, I would observe in conclusion that
what I consider novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,

page_text: the construction of hollow rolls for rolling mills, substantially as hercin-
before described and shown on the annexed Sheet of Drawings.
In witness whereof, I, the said John Dick, have hereunto set my
hand and seal, this Twenty-second day of November Eighteen
hundred and sixty-nine.
