Year: 1860

page_text: LETTERS PATENT to Bernard Lauth, of the City of Manchester, in the
County of Lancaster, Engineer, for the Invention of "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR STRAIGHTENING METAL BARS, RAILS, RODS,
Sealed the 17th October 1860, and dated the 19th April 1860.
PROVISIONAL SPECIFICATION left by the said Bernard Lauth at the
Office of the Commissioners of Patents, with his Petition, on the
19th April 1860.
I, BERNARD LAUTH, of the City of Manchester, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR STRAIGHTENING METAL BARS, RAILS,
RODS, TUBES, PLATES, AND OTHER SIMILAR ARTICLES," to be as follows:-
I cause each bar, rail, rod, tube, or plate to pass between a double set of
rollers, consisting of two or more rollers at the top, and two or more at the
bottom, the centres of the top rollers being placed between the centres of the
bottom rollers. The said rollers are either grooved, flat, or of any suitable
form, according to the kind of article to be straightened, and the positions of
their bearings are regulated by screws or wedges, either acted upon separately
or simultaneously.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Nineteenth day of April, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Bernard Lauth, Her special licence that I, the said Bernard
Lauth, my executors, administrators, and assigns, or such others as I, the said
Bernard Lauth, 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 "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR STRAIGHTENING METAL BARS, RAILS,
RODS, TUBES, PLATES, AND OTHER SIMILAR ARTICLES," upon the condition (amongst
others) that I, the said Bernard Lauth, 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 Inven-
tion, 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 Lotters Patent.
NOW KNOW YE, that I, the said Bernard Lauth, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
I cause each bar, rail, rod, tube, or plate to pass between a double set of
rollers consisting of two or more rollers at the top, and two or more at the
bottom, the centres of the top rollers being placed between the centres of the
bottom rollers. The said rollers are either grooved, flat, or of any suitable
form, according to the kind of article to be straightened, and the positions of
their bearings are regulated by screws or wedges, either acted upon separately
or simultaneously.
The manner in which my Invention is to be performed will be clearly
understood by referring to the figures and letters on the accompanying Sheet
of Drawings, in which Figure 1 is a transverse section, Figure 2 a plan, and
Figure 8 a transverse elevation of one of my improved arrangements of rollers
for flattening plates.
The top rollers are shown at a, and the bottom rollers at b, the centres of
the top rollers being placed between the centres of the bottom rollers; the
gudgeons of all the rollers work in suitable bearings in the framework c.
A bottom roller at each end is turned in the direction of the passage of the

page_text: plate by the gearing d, and at the front of the machine are gripping or
nipping rollers to advance the plate, and at the back another pair of similar
rollers to deliver it from the machine.
For straightening round, square, or other shaped bars, rails, or tubes, the
rollers are placed in a similar position, but they are grooved or shaped
according to the form of the article to be straightened.
The rollers, framework, and gearing are made of any required strength, and
the rollers are placed at any suitable distance apart, and also any required
number of rollers may be used.
Ilaving now described the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be distinctly
understood that I claim as my Invention, and which, to the best of my
knowledge and belief, has not been hitherto used within the realm, the
employment of a double set of two or more rollers for straightening bars, rails,
rods, tubes, or plates, having the centres of one set placed between the centres
of the other set, the rollers being plain, grooved, or otherwise shaped, accord-
ing to the shape or kind of article to be straightened or flattened.
In witness whereof, I, the said Bernard Lauth, have hereunto set my
hand and seal, this Sixteenth day of October, in the year of our Lord
One thousand eight hundred and sixty.

said Bernard Lauth,
