IMPROVEMENTS IN MACHINERY FOR STRAIGHTENING AND POLISHING CYLINDRICAL BARS OF IRON AND OTHER METALS." PROVISIONAL SPECIFICATION
Year: 1862

page_text: LETTERS PATENT to Ambrose Edmund Heath Buckley Butler, of the
Kirkstall Forge Company, Leeds, in the County of York, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY FOR STRAIGHTENING AND POLISHING
CYLINDRICAL BARS OF IRON AND OTHER METALS."
PROVISIONAL SPECIFICATION left by the said Ambrose Edmund Heath
Buckley Butler at the Office of the Commissioners of Patents, with his
Petition, on the 12th September 1862.
I, AMBROSE EDMUND HEATH BUCKLEY BUTLER, of the Kirkstall Forge.
Company, Leeds, in the County of York, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR STRAIGHTENING AND
POLISHING CYLINDRICAL BARS OF IRON AND OTHER METALS," to be as follows:-
After bars of iron or other metal have been rolled by passing between
grooved rollers in the ordinary manner, they are generally crooked, and the
surface is not perfectly smooth. Now, in order to render them straight, and to
polish the surface, I place them on leaving the grooved rollers between two
rolls, the length of which must be equal to or rather exceed the length of the
longest bar to be operated upon. Above the two rolls is a third roll, which is
pressed down upon the bar, the three rolls are caused to revolve rapidly, and

page_text: in revolving they impart a rotary motion to the bar between them, thereby
rendering it perfectly straight and imparting a polish to its surface. As soon
as one bar has been operated upon the top roll is raised by screws, weighted
levers, or other equivalents; the finished bar is then removed and another
put in its place. In some cases two rolls or more than three rolls may be
employed for straightening and polishing the bars, which may be operated
upon when cold, and the arrangement of the machinery may be otherwise
modified.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ambrose Edmund Heath Buckley Butler in the Great Seal
Patent Office on the 9th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AMBROSE
EDMUND HEATH BUCKLEY BUTLER, of the Kirkstall Forge Company, Leeds,
in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of September, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Ambrose Edmund Heath Buckley Butler, Her special license, that I, the
said Ambrose Edmund Heath Buckley Butler, my executors, administrators,
and assigns, or such others as I, the said Ambrose Edmund Heath Buckley
Butler, my executors, administrators, and assigns, should at any time agreo
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 MACHINERY
FOR STRAIGHTENING AND POLISHING CYLINDRICAL BARS OF IRON AND OTHER METALS,"
upon the condition (amongst others) that I, the said Ambrose Edmund Heath
Buckley Butler, 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 Ambrose Edmund Heath Buckley
Butler, do hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say):-
After bars of iron or other metal have been rolled by passing between
grooved rollers in the ordinary manner they are generally crooked and the
surface is not perfectly smooth. Now, in order to render them straight, and to
polish or give a high finish to the surface, I place them; on leaving the
grooved rollers, between two rolls, the length of which must be equal to or
rather exceed the length of the longest bar to be operated upon; above the
two rolls is a third roll which is pressed down upon the bar, the three rolls
are caused to revolve rapidly, and in revolving they impart a rotary motion to
the bar between them, thereby rendering it perfectly straight and imparting
a high finish to its surface. As soon as one bar has been operated upon the
top roll is raised by screws, weighted levers, or other equivalents, the finished
bar is then removed and another put in its place. The bars may be operated
upon when cold, and the arrangement of gearing for driving the machinery
may be modified.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the accompanying Sheet of
Drawings, reference being bad to the figures and letters thereon.
Figure 1 is an end elevation; Figure 2 is a transverso section; Figure 3
is a plan, and Figure 4, a front elevation, of my improved machinery for
straightening and finishing bars of metal. a, a, are the end standards, and b, b,
the intermediate standards; c and d are two rolls supported at each end in
bearings in the standards a, and in the centro by the antifriction rollers c¹
and d. The third roll e revolves in the adjustable bearings a', fitting within
the end standards a. The antifriction rollers e' above the roll e, are supported
in the blocks f, which slide between the side beams 9; the ends of the beams
are secured to the end standards a, and connect the whole framing together.
The centre beam h, placed between the rolls c and d, is suspended by the
clips or straps o, to the ends of the roll e, and moves up and down with
the roll e, so that when the bar i is straightened and finished, in raising the
roll e with the screws n, the beam h is raised also and forces the bar i upwards
from between the rolls c and d; when thus lifted to a sufficient height the
bar i can easily be removed and replaced by another. The object of the
antifriction rollers c', d', and e', is to prevent the deflection of the rolls c, d,
and e, and it is evident that when the rolls are shorter, a single set of anti-
friction rollers will be sufficient, and that when the rolls are longer three or
more sets may be required. The requisite rotary motion is given to the two
rolls c and d in the following manner :-j is the driving shaft provided with a

page_text: fast and loose pulley and, and with two spur pinions 3; the ends of the
shaft j revolve in the standards k, and each pinion gears into a wheel 2,
fixed upon short shafts l', supported in bearings attached to the standards a
and k. To the shafts are also fixed the pinions, one of which geers into
the wheel on the roll c, and the other into the wheel d on the roll d; the
roll e rotates by the friction of the bar i, and it is raised and depressed by the
shaft m, which is furnished with two pairs of fast and loose pulleys m³, m³,
and m³, m, one pair of which is driven by an open strap, and the other by a
crossed strap; on the shaft m are fixed the worms m³, geering into worm
wheels n on the screws n', which act on the bearings a', and on the blocks f.
The mode of operation is as follows:-The roll e having been raised, the bar
of metal i to be operated upon, either heated or cold, is placed upon the
rolls c and d, rotary motion is then given to these rolls by shifting the driving
strap to the fast pulley j', the shaft m is then put in motion by shifting its
driving strap to the pulley m, and it is made to rotate in the proper direction
for lowering the roll e until it comes in contact with, and presses upon the
bar i; the pressure on the roll e is maintained until the bar is straightened
and the surface thereof polished or finished. As soon as the bar has been
sufficiently operated upon the direction of motion of the shaft mis reversed to
raise the rolle and the beam h, the finished bar i is then removed and
another one put in its place, when the operations are repeated as before.
I wish to observe that weighted levers or other equivalents may be employed
instead of the screws n¹.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim the improved combina-
tion and arrangement of machinery as shewn and described for straightening
and polishing or finishing cylindrical bars of iron and other metals.
In witness whereof, I, the said Ambrose Edmund Heath Buckley Butler,
have hereunto set my hand and seal, the Fifth day of March, in the
year of our Lord One thousand eight hundred and sixty-three.
