Year: 1858

page_text: LETTERS PATENT to Leon Talabot, of No. 57, Rue de la Chaussée
d'Antin, Paris, Merchant, for the Invention of "IMPROVEMENTS IN ROLLING
RAILWAY AND OTHER BARS."
Sealed the 9th July 1858, and dated the 1st May 1858.
PROVISIONAL SPECIFICATION left by the said Leon Talabot at the Office
of the Commissioners of Patents, with his Petition, on the 1st May
1858.
I, LEON TALABOT, of No. 57, Rue de la Chaussée d'Antin, Paris, Merchant,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN ROLLING
RAILWAY AND OTHER BARS," to be as follows:-
In rolling railway and other bars when what are called "three high rolls"
are employed, the middle row is formed according to this Invention with
alternate grooves and projections, the projections on the middle roll enter into
grooves in the lowest roll, and projections on the highest roll enter into grooves
in the middle roll, and the metal in rolling is passed alternately through the
spaces between the middle and upper rolls, and between the middle and lower
rolls. Thus, the spaces between the rolls through which the metal is passed
are always enclosed by grooves in the lower and projections on the upper of
the two rolls, between which each of such spaces is formed, except when passing
a railway bar for the last time through the rolls, when in order to round off
the top of the rail the space between the rolls is enclosed by grooves in each
roll. The distances between the rolls in a vertical direction are adjusted by

page_text: means of wedges acted on by screws, the wedges being placed between the
bearings of the rolls. The adjustment of the rolls in a horizontal direction
and at right angles to their axes is by means of screws passing through the
side of the frame. The adjustment of the rolls in a horizontal direction and
parallel to their axes is, as heretofore, by screws passing through the end of
the frame. The bar coming from the lowest grooves is raised by means of a
lever which is suspended from the axis of a wheel which runs on a rail above
the rolls; the rail is connected with levers, so that it may be raised and
lowered. By these means the bar may readily be moved sideways, in addition
to being raised and lowered.
The other part of this Invention has for its object improvements in rolling
round bars of iron. Heretofore iron of this section has sometimes been rolled
in the following manner: -The bloom has been first passed under the roughing
rolls through grooves of an oval, gothic, or other form, so as to produce a bar
approaching in area of section the size required, and between each passage
under the rolls the bar has been turned partly round by hand; the bar has
then gone to the finishing rollers, in which oval grooves are formed, and
during this rolling the bar has been kept constantly with its longest diameter
in a vertical position by means of lateral guides, to do which it was necessary
to turn the bar exactly one quarter round between each passage between the
rolls, and by rolling in this way the bar was finished.
Now, according to this part of the Invention, the bars are rolled in the way
already described, only that in place of finishing the bars by rolling with
guides, which makes it necessary to turn the bar one quarter round between
each passage, the bar is finished (after first drawing it down without guides
and then rolling it with guides) by again rolling without guides, the bar being
turned to a greater or less degree between each passage under the rolls
according to the judgment of the roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Leon Talabot in the Great Seal Patent Office on the 3
1st November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEON
TALABOT, of No. 57, Rue de la Chaussée d'Antin, Paris, Merchant, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 35
Patent, bearing date the First day of May, in the year of our Lord

page_text: One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Leon Talabot, Her special licence that I, the said Leon Talabot, my
executors, administrators, and assigns, or such others as I, the said Leon
Talabot, my executors, administrators, and 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 ROLLING
RAILWAY AND OTHER BARS," upon the condition (amongst others) that I, the
said Leon Talabot, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Leon Talabot, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
In rolling railway and other bars when what are called "three high rolls"
are employed, the middle roll is formed according to this Invention with
alternate grooves and projections. The projections on the middle roll enter
into grooves in the lowest roll, and projections on the highest roll enter into
grooves in the middle roll; and the metal in rolling is passed alternately
through the spaces between the middle and upper rolls, and between the
middle and lower rolls. Thus, the spaces between the rolls through which
the metal is passed are always enclosed by grooves in the lower and pro-
jections on the upper of the two rolls, between which each of such spaces is
formed, except when passing a railway bar for the last time through the rolls,
when in order to round off the top of the rail the space between the rolls is
enclosed by grooves in each roll. The distances between the rolls in a
vertical direction are adjusted by means of wedges acted on by screws, the
wedges being placed between the bearings of the rolls. The adjustment of
the rolls in a horizontal direction and at right angles to their axes is, by
means of screws passing through the side of the frame. The adjustment of
the rolls in a horizontal direction and parallel to their axes is, as heretofore,
by screws passing through the end of the frame. The bar coming from the
lowest grooves is raised by means of a lever which is suspended from the axis

page_text: of a wheel which runs on a rail above the rolls. The rail is connected with
levers, so that it may be raised and lowered. By these means the bar may
readily be moved sideways, in addition to being raised and lowered.
The other part of this Invention has for its object improvements in rolling
round bars of iron. Heretofore, iron of this section has sometimes been
rolled in the following manner:-The bloom has been first passed under the
roughing rolls, through grooves of an oval, gothic, or other form, so as to
produce a bar approaching in area of section the size required, and between
each passage under the rolls the bar has been turned partly round by hand;
the bar has then gone to the finishing rolls, in which oval grooves are formed,
and during this rolling the bar has been kept constantly with its longest
diameter in a vertical position by means of lateral guides, to do which it was
necessary to turn the bar exactly one quarter round between each passage
between the rolls, and by rolling in this way the bar was finished. Now,
according to this part of the Invention, the bars are rolled in the way already
described, only that in place of finishing the bars by rolling with guides,
which makes it necessary to turn the bar one quarter round between each
passage, the bar is finished (after first drawing it down without guides, and
then rolling it with guides) by again rolling without guides, the bar being
turned to a greater or less degree between each passage under the rolls,
according to the judgement of the roller.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.

DESCRIPTION OF THE DRAWINGS.
Figures 1, 2, and 3, Sheet No. 1, shew sets of three high rolls for rolling
railway bars of different sections; and Figure 4 shews a set of three high
rolls for rolling a wrought-iron trough rail or beam, arranged according to
my Invention. In each case, the middle roll 6 is formed with alternate
grooves 6¹ and projections 62; the projections 62 enter into grooves c¹ in the
lowest roll c, and projections a' on the bighest roll a enter into the grooves b
in the middle roll b. The metal in rolling is first passed through the space 1
formed between the middle roll 6 and the lowest roll c, then between the
space 2, formed between the highest roll a and the middle roll 6, then through
the space 3, and so on, until the bar is brought to the required shape; but
when passing some sections of railway bars for the last time through the rolls
the space between is formed by grooves in each roll, as shewn at space 5
Figures 1 and 2, in order to round off the top of the rail. The forming the
middle roll with.alternate grooves and projections so that the space between

page_text: the rolls are formed by projections on the highest roll and grooves in the
lowest, creates on the profile of each cylinder what I call the double collar.
The double collar is the necessary consequence of the spaces between the rolls
being always formed by a groove in the lowest roll. The double collar is
called double because it is doubly cut away, as shewn in the Drawings,
Sheet No. 1.
Figure 1, Sheet No. 2, is an end view of a set of three high rolls, shewing
the manner of adjusting the distance between the rolls in a vertical direction.
a, a, are wedges placed between the bearings b, b, of the rolls; to each of
the wedges a is connected a screw c, the end of which passes through the
framing A, shewn in edge view at Figure 2, and in plan at Figure 5), and on
the exterior of the frame A, a nut d screws on to the screw c, the collar of
the nut d working against the framing A, so that by turning the nuts d, the
distance between the rolls can be adjusted without stopping the movement of
the rolls; separate views of the wedges and screws and nuts are shown at
Figure 3. Figures 4 shew a side view and plan of a method of acting on
the wedges which adjust the distances between the rolls by means of two
screws. a, a, are the wedges, which are acted on by the screws b, b; each
of the screws 6 works in a nut c, which is fixed in the inside of the framing A,
and on each of the screws 6 there is another nut d which screws against the
exterior of the framing. The wedges are first adjusted by turning the
screws by means of a handle on their ends ', the nut d is then screwed
against the framing to prevent the screw from turning. The adjustment of
the rolls in a horizontal direction and at right angles to their axes is by
means of screws e, which screw through nuts f fixed in the framing A ; on one
end of each of the screws e there is a head h, and the other ends of the screws
press directly against the bushes g. There is also another nut k which screws
on the screws e, which, when the rolls are adjusted, is screwed against the
framing prevent the screws e from turning. The adjustment of the rolls
in a horizontal direction and parallel to their axes is, as heretofore, by screws
passing through the end of the frame.
Figures 1 and 2, Sheet No. 3, are side and end views of the apparatus for
raising and lowering the bar as it comes from between the rolls, and also for
moving the bar sideways. The bar as it comes from between the rolls is received
on the hook of the lever a, which is suspended by means of the chain 6, from
the axis of the wheel c, which runs on the rail d. The rail d is supported by
the rods e, which are connected to the arms f¹ of the levers f. The levers f turn
on the same axis g, which turns in bearings, supported by the beams h, h. The
bar, after it has come from between the lower rolls, and been received on the

page_text: hook of the lever a, is raised to the position shown by dotted lines by depressing
the arm of the lever f, by drawing down the rod k, which may either be done
by hand or by the power which turns the rolls; the bar is also moved slightly
sideways, so that the end of the bar may be placed between the next space
between the upper and middle rolls.
According to the next part of this Invention, bars of a circular section are
formed by first passing the bloom through grooves between the rolls, such as
shewn from Figures 1 to 11, or through grooves of any other suitable form,
so as to produce a bar approaching in area of section the size required. The
bar is then passed through grooves, such as are shewn at Figures 12 and 13,
the bar being kept with its longest diameter in a vertical direction by means
of lateral guides, the bar being turned one quarter round between each
passage through the rolls. The bar is then lastly passed through grooves
between the rolls of a semicircular section without the use of guides. By
thus first rolling without guides, then preparing the bar for finishing by
rolling with guides, and then for the last time rolling without guides, it is
in some cases only necessary to pass the bars once through the finishing rolls,
and thus a saving of labor is obtained. This system of rolling is applicable
to bars varying from ths of an inch to one inch in diameter.
In witness whereof, I, the said Leon Talabot, have hereunto set my
hand and seal, this Twenty-seventh day of October, in the year of
our Lord One thousand eight hundred and fifty-eight.

T. BASSET.
