Year: 1863

page_text: LETTERS PATENT to George Taylor, of Leeds, in the County of York, Iron
Manufacturer, for the Invention of "IMPROVEMENTS IN SHAPING BOILER
AND OTHER PLATES AND IN APPARATUS EMPLOYED THEREIN."
Sealed the 29th January 1864, and dated the 1st August 1863.
PROVISIONAL SPECIFICATION left by the said George Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
1st August 1868.
I, GEORGE TAYLOB, of Leeds, in the County of York, Iron Manufacturer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SHAPING BOILER AND OTHER PLATES AND IN APPARATUS ENPLOYED THEREIN," to be
as follows:
My improvements in shaping boiler and other plates consist in a method of
flanging the plates by apparatus and machinery as hereafter described.
At present the plates which are to be flanged, after being rolled and sheared
to the dimensions required, are placed in a furnace, and after being properly
warmed they are fixed on blocks and the edges are then hammered down.
My Invention consists in flanging plates by dies in a press, to be worked either
by screws or levers, but I prefer to work it by hydraulic power, and by using
an accumulator I at once bring down the press upon a set of dies the smallest
of which is the proper internal size and shape the plate is required to be, and
the larger or top die is made so much larger than the first by the thickness
of the plate. To suit variations in the thicknesses of the plates I make the sides
of the dies articulated or jointed, and by means of springs and screws I keep
the loose parts so tight together as to flange the plates, and at the same time
the dies yield without breaking when a thicker plate is acted on. I also
mako the dies to expand and contract to suit different sizes of boilers, and for

page_text: this purpose I make them in several pieces by taking out or inserting pieces
as may be required. I make my dies of different sizes. To prevent that part
of the plate which is not acted on by the dies from buckling or bending, I
press a strong plate down on the surface of the boiler or other plate, and
retain it there with screws, levers, or, as I prefer it, by hydraulic pressure.
In some cases I flange plates while at the same heat as that at which they
are rolled, but my Invention is applicable for flanging plates while either cold
or hot, and for flanging the edges square or to any required bevil, while the
section may be varied from the arc of a circle to a right angle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Taylor in the Great Seal Patent Office on the 1st
February 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TAYLOR, of Leeds, in the County of York, Iron Manufacturer, send
greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of August, 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 me, the said George Taylor, Her special licence that I, the said
George Taylor, my executors, administrators, and assigns, or such others
as I, the said George Taylor, 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
"IMPROVEDENTS IN SHAPING BOILER AND OTHER PLATES AND IN APPARATUS EMPLOYED
THEREIN," upon the condition (amongst others) that I, the said George
Taylor, 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 George Taylor, do hereby declare
the nature of my said Invention, and in what manner, the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say :-
My improvements in shaping boiler and other plates consist in a method of
flanging the plates by apparatus and machinery as hereafter described.
At present the plates which are to be flanged, after being rolled and sheared
to the dimensions required, are placed in a furnace, and after being properly
warmed they are fixed on blocks and the edges are then hammered down.
My Invention consists in flanging plates by dies in a press worked either by
screws, levers, or hydraulic pressure, in manner hereafter described. I fix the
plates to be flanged on the bottom die by hydraulic pressure or by a lever and
plate as shown; the bottom die is the proper internal shape and size the plate
is required to be, and the larger or top die is, when brought home to its work,
so much larger than the first by the thickness of the plates to suit variations
in the thickness of the plates. I make the dies in segments and expand or
contract them by means of wedges, screws, and inclined guides.
In some cases I flange plates while at the same heat as that at which they
are rolled or I reheat them, and I flange the edges square or to any
required bevil, while the section may be varied from the are of a circle to a
right angle.
:
In the accompanying Drawings I proceed to shew the manner in which
I carry my said Invention into effect.
Figure 1 is a sectional elevation; Figure 2 is a plan of the bottom die
through the line B, C, of Figure 1; Figure 3 is a plan of the top dics
from the line B, C, shewing my arrangements of apparatus for shaping boiler
and other plates.
A, A, Figure 1, is a foundation or bed; B, B, are standards attached to
the bed A, A, for supporting the upper and fixed block and dies, to be here-
after described; C, C, are hydraulic cylinders fitted to the foundation; D, D,
are the rams connected to the plate E, E, on which is placed the bottom
die F, F, shewn in detail in Figure 2; G, G, are guide blocks attached to the
plate E, which have a slot cast in them partly inclined and partly straight, as
shewn in Figure 1, and are adjustable at top and bottom by screws as shown,
in order to make the flanging dies to which they are attached suitable to
different dimensions of plates; H is a plate which is brought down on the
plate to be flanged by means of a lever, screw, and balance weight, as shewn
in Figure 1, to secure the plate on the bottom die while under the operation
of flanging; J, J, is the upper stationary block fitted all round its edges with
adjustable segmental dies J, I; K, K, are pieces attached to the dies by bolts

page_text: having long slots in them, through which the pieces G, G, pass; L, L, aro
rollers which fit the inclined slots in the pieces G, and are secured to the
pieces K and the flanging dies I by means of a pin as shewn. When a plate,
represented by x, Figure 1, is to be shaped by flanging the edges thereof, it is
warmed, and placed upon the bottom die F, F, as shewn, and the plate His
brought down to fix it with sufficient pressure to prevent it being drawn out
of its proper place when under the operation of the flanging dies I, I. Com-
munication is now made between the bottom of the hydraulic cylinders C, C,
and an accumulator, whereby the bed plate E, E, carrying the bottom die F, F,
on which is fixed the plate a to be flanged, are raised, and the inclined
guides G, G, being also raised, the flanging dies are by the inclined slot and
roller made to approach the lower segmental dies, pressing all the time the
outer edge of the plate to be flanged against the bottom die, until the roller
has passed the inclined part of the guiding slot; the straight part allows the
surfaces of F, F, and I, I, to be brought to bear on the plate and straighten
it on its flat surface. Communication is now made between the upper part of
the hydraulic cylinders and the accumulator, and the water from the under
part being allowed to run out, the rams descend, as also the plate E, E, and
the dies F, F; hooks attached to the upper plate J, J, are brought down
over the flanged edges of the plate, and by this means it is drawn off tho
die F, F. The faces of the segmental dies must be altered to suit different
shapes of flange.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, shaping boiler.
and other plates by flanging the edges thereof. by means of machinery or
apparatus consisting chiefly of two sets of segmental dies made to approach
and act on the edges of the plate to be flanged substantially in manner herein-
before described.
In witness whereof, I, the said George Taylor, have hereunto set my hand
and seal, this Twentieth day of January, One thousand eight hundred
and sixty-four
GEORGE TAYLOR. (L.S.)
