page_text: LETTERS PATENT to George Heaton Daglish and Thomas Windus, both
of Saint Helen's, Lancashire, Engineers, for the Invention of "IMPROVE-
MIX MACHINE PAD REV DES PAR IDAY SHIPS LUD OTHER TIRE
PROVISIONAL SPECIFICATION left by the said George Heaton Daglish.
and Thomas Windus at the Office of the Commissioners of Patents, with.
their Petition, on the 20th October 1863.
We, GEORGE HEATON DAGLISH and THOMAS WINDUS, both of Saint Helen's,
Lancashire, Engineers, do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN MACHINERY FOR BENDING PLATES FOR IRON SHIPS AND
OTHER LIKE PURPOSES," to be as follows:-
This Invention relates to the bending of the "garboard strake" of plates
for iron ships, and consists in the application and use for that and similar
purposes of a set of double or single purchase crab or other gearing in com-
bination with a toothed quadrant fixed at each end of the machine, each end
of a movable roller being carried by one of the quadrants in a universal joint
capable of being moved nearer to or further from the main blocks of the
machine to suit the different thicknesses of plates to be bent. The quadrants
are carried upon gudgeons cast upon the bottom block at each end, the top
block being suspended by balance levers and toothed quadrants over the
bottom block, and when lowered down on to the plate to be bent is firmly

page_text: secured by cotter bolts or other suitable means. The plate may be bent
either up or down as may be most convenient, but it has been found in
practice better to bend it upwards, as it is then more easy to apply the gauges
to ascertain when the plate has received the required curvature; one end of
the roller can be moved independently of the other by means of the universal
joints before mentioned. The top block is cast hollow, so as to contain water,
and thus keep it at a low temperature, and can be moved up and down with
the greatest facility by means of balance levers, the toothed quadrants
preserving its level, and preventing it from getting fast. The gearing can
be worked by manual labour or steam power, but the former is preferred, as
the number of hands requisite to handle the plate in bringing it from the
furnace are sufficient to work the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Heaton Daglish and Thomas Windus in the Great
Seal Patent Office on the 20th April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HEATON DAGLISH and THOMAS WINDUS, both of Saint Helen's, Lancashire,
Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of October, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Heaton Daglish and Thomas Windus, Her special license
that we, the said George Heaton Daglish and Thomas Windus, our executors,
administrators, and assigns, or such others as we, the said George Heaton
Daglish and Thomas Windus, our 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 MACHINERY FOR BENDING PLATES FOR IRON SHIPS AND OTHER
LIKE PURPOSES," upon the condition (amongst others) that we, the said George
Heaton Daglish and Thomas Windus, our executors or administrators, by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us or them, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and

page_text: 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 we, the said George Heaton Daglish and Thomas
Windus, do hereby declare the nature of our said Invention, and in what
5 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
Our said Invention relates to the bending of the " garboard strake" of
plates for iron ships, and consists in the application and use for that and
similar purposes of a set of double or single purchase crab or other gearing,
in combination with a toothed quadrant fixed at each end of the machine,
each end of a moveable roller being carried by one of the quadrants in a
universal joint capable of being moved nearer to or further from the main
blocks of the machine to suit the different thicknesses of plates to be bent.
The quadrants are carried upon gudgeons cast upon the bottom block at each
end, the top block being suspended by balance levers and toothed quadrants
over the bottom block, and when lowered down on to the plate to be bent is
firmly secured by cotter bolts or other suitable means. The plate may be
bent either up or down as may be most convenient, but it has been found in
practice better to bend it upwards, as it is then more easy to apply the guages
to ascertain when the plate has received the required curvature; one end of
the roller can be moved independently of the other by means of the universal
joints before mentioned. The top block is cast hollow, so as to contain water,
and thus keep it at a low temperature, and can be moved up and down with
the greatest facility by means of balance levers, the toothed quadrants
preserving its level, and preventing it from getting fast. The gearing can
be worked by manual labour or steam power, but the former is preferred, as
the number of hands requisite to handle the plate in bringing it from the
furnace is sufficient to work the machine.
And in order that our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose we shall
refer to the several Figures on the three Sheets of Drawings hereunto
annexed, the same letters of reference indicating corresponding parts in all
the Figures.
Figure 1 of the accompanying Drawings represents a front elevation of the
machine; Figure 2 is a ground plan of the same; Figure 3 is an end
elevation; Figure 4 is a cross section of the top and bottom blocks and
roller; Figure 5 is a cross section shewing the application of wood blocks or

page_text: moulds; and Figures 6, 7, and 8 represent details of the swivel adjustable
bearing for carrying the ends of the bending roller.
A is a top block, which is cast hollow, and filled with cold water, which
may be allowed to circulate through it to equalize its temperature when in
contact with a hot plate. In combination with this. block there is a bottom
block B, which may also be arranged to be filled with water if thought
necessary, a bending roller C, two quadrants D, D, working on gudgeons
cast on the end of the bottom block B, and carrying the bending roller C, two
sets of double purchase crabs or other gearing E, E, for working the quadrants
D, D, and two balance levers F, F, for balancing the top block A (to which
they are attached by the links G, G, G, G.) with toothed quadrants at the
long end of the levers working into each other, so as to ensure the top blocks
rising and falling uniformly parallel to the bottom block B. The short ends
of these levers are provided with a socket H, in which to insert a crowbar to
move the top block A up or down as required, which can be done with the
greatest ease when properly balanced. The bottom block B has two strong
cotter bolts I, I, I, I, at each end, which pass vertically through the top
block A, and are prolonged so as to carry the knife edge centres of the balance
levers F, F. The plate to be shaped is first heated, and then inserted and
nipped between the top and bottom blocks, which are then firmly drawn together
by driving the cotters into the cotter bolts I, I, as shewn in Figure 4. The
plate can either be bent up or down, but it is found preferable to bend it
upwards, when the guage can be more readily applied so as to ascertain when
the required shape has been obtained. By the use of a peculiar swivel bearing
fixed in the arms of the quadrant D, D, and carrying the end of the bending
roller C, as shewn in Figures 6, 7, and 8, one end of the roller can be moved
up or down independently of the other end, and each end can be moved nearer
to or further from the machine, and thus any degree of twist from a straight
line to a right angle can be given to the plate, or both ends of the roller can
be moved simultaneously if required. By the use of wood blocks or moulds
secured to the bottom block B, as shewn in Figure 5, any required curve may
be given to the plate, instead of merely twisting or bending; in this case it
will be found preferable to bend the plate downwards, as shewn in Figure 5.
The double purchase crab gearing E, E, at each end of the machine can be
worked either by manual labor or by steam power, but the former is preferred,
as the number of hands necessary for bringing the plate from the furnace to
the machine is quite sufficient to perform the operation.
Having now described and particularly ascertained the nature of our said.
Invention, and the manner in which the same is or may be used or carried

page_text: into effect, we would observe in conclusion that what we consider to be novel
and original, and therefore claim as the Invention secured to us by the herein-
before in part recited Letters Patent, is,―
1st. The application and use to and in machinery or apparatus for bending
plates for iron ships and other like purposes of a double or single purchase
crab, or other equivalent gearing for actuating each end of the bending roller,
substantially as herein-before described.
2nd. The application of swivel or universal adjustable bearings for carrying
the ends of the bending roller, as herein-before described.
3rd. The system or mode of balancing the top block A by means of balanced
levers provided with toothed quadrants geared together, as herein-before
described.
In witness whereof, I, the said George Heaton Daglish, have hereunto
set my hand and seal, on behalf of myself and the said Thomas
Windus, this Sixteenth day of April, One thousand eight hundred and
sixty-four.
