Year: 1870

page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John
Gedge and Son, of No. 11, Wellington Street, Strand, in the County
of Middlesex, Patent Agent, for the Invention of "AN IMPROVEMENT
IN ROLLING MILLS OR MACHINES FOR MANUFACTURING ROUND AND SQUARE
BAR IRON." A communication from abroad by Hyacinthe Vigour,
of Charleville, Ardennes, France, Iron Merchant.
Sealed the 21st April 1871, and dated the 26th October 1870.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 26th October 1870.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,
of No. 11, Wellington Street, Strand, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT IN ROLLING MILLS OR MACHINES FOR MANUFACTURING ROUND
AND SQUARE BAR IRON," a communication to me from abroad by Hyacinthe
Vigour, of Charleville, Ardennes, France, Iron Merchant, to be as
follows:
-
It has hitherto been found impossible to manufacture on the same bar
round and square iron of equal diameter in the round and in the square

page_text: part, whether by means of vertical or of horizontal grooved rolls, and
this arises from the inability to gear or set the bar delivered from the
first rolls into the second pair with such precision as to ensure perfect
coincidence of the square and round parts with the grooves of the
finishing roll. It is proposed to overcome this difficulty by placing a
channel or guide between the roughing and the finishing rolls, as shewn
on the accompanying Sheet of Drawing, on which A indicates the
channel or guide; B, first roll; C, second roll; D, frame; E, bar. This
application ensures the exactness and precision. necessary to obtain a
perfectly regular bar, which has hitherto been unattainable.
This Invention while of great simplicity is also of great importance,
and may be summed up as consisting in the application to all rolling
mills or machines for manufacturing round or square iron on a single
bar of a channel or guide for delivering the iron with precision from one
set of rolls into the other.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 25th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11,
Wellington Street, Strand, in the County of Middlesex, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of October, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Gedge, Her special
licence that I, the said William Edward Gedge, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward
Gedge, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 "AN IMPROVEMENT IN ROLLING MILLS OR MACHINES FOR MANUFACTURING

page_text: ROUND AND SQUARE BAR IRON," a communication to me from abroad by
Hyacinthe Vigour, of Charleville, Ardennes, France, Iron Merchant, upon
the condition (amongst others) that I, the said William Edward Gedge,
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 immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Gedge, 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, reference being had to the accompanying Sheet
of Drawing and to the figures and letters of reference placed thereon:-
-
.
It has hitherto been found difficult to manufacture on the same bar
round and square iron of equal diameter in the round and in the square
part, either with vertical or with horizontal grooved rolls, and this arises
from the inability to gear or set the bar delivered from the first rolls
into the second pair with such precision as to ensure perfect coincidence
of the square and round parts with the grooves of the finishing roll.
This Invention relates to the use of a channel or guide placed
between the roughing and the finishing rolls, which channel or guide
receiving the bar as it issues from the first rolls delivers it to the second
with all the exactness and precision necessary to ensure a perfectly

tion communicated to me as aforesaid, I would have it understood that
I claim as secured to me by the herein-before in part recited Letters
Patent, the application to all rolling mills or machines for manufacturing
bar iron of a channel or guide for delivering the iron with precision from
one set of rolls into the other, substantially as and for the purpose
herein-before set forth.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and seal, this Twenty-fifth day of April,
in the year of our Lord One thousand eight hundred and seventy-
