Year: 1863

page_text: LETTERS PATENT to John Fernie, of Derby, in the County of Derby,
Engineer, and George Taylor, of Leeds, in the County of York, Iron-
master, for the Invention of "IMPROVEMENTS IN MACHINERY FOR SHAPING
PROVISIONAL SPECIFICATION left by the said John Fernie and George
Taylor at the Office of the Commissioners of Patents, with their Petition,
on the 30th November 1868.
We, JOHN FERNIE, of Derby, in the County of Derby, Engineer, and
GEORGE TAYLER, of Leeds, in the County of York, Ironmaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
SHAPING THE EDGES OF BOILER AND OTHER PLATES," to be as follows:-
The edges of boiler and other like plates are generally ragged and uneven
when they have the rolls, and the object of our Invention is to finish and
shape the edges while the plates are still hot to the exact shape and dimension
required for the use to which they are destined.
Our Invention consists of a machine constructed and acting in manner
hereafter described. On the four corners of a rectangular metal frame we fix
4 pillars; the upper ends of these pillars support a similar rectangular frame,
and all are bolted together. On the lower frame are fitted two movable beds,
which can be placed slightly deviating from the parallel if required; each of
these beds carries a sliding saddle moved by a screw or other convenient

page_text: On the upper side of these saddles is cast an upright upon which
another saddle is fitted capable of being moved vertically by screw and bevil
gearing. Each of these vertical saddles carries an oscillating headstock
provided with suitable journals, into which is fitted a spindle; on one end of
this spindle there is a turbine or Barker's mill, which is actuated by high-
pressure steam, and on the other end a saw suitable for cutting heated iron is
mounted. Two of these saws and their apparatus are mounted upon the beds
which are carried upon the lower rectangular frame. Two movable beds of
similar construction to the lower beds are connected to and carried by the
upper rectangular frame. These movable beds are supplied with similar
saddles, headstocks, spindles, saws, and motive gear to those already described,
but have in addition a transverse slide fitted to the saddle; this transverse
slide is governed by a "copy"-or former, which will cause the saw to traverse
slightly from a straight line.
In the centre of the rectangular frame we fix a hydraulic cylinder provided
with a ram; on the top of this ram a table of cast iron is mounted, and over
this table, firmly fixed to the upper rectangular frame, is a table of similar
shape and construction to the lower one. If a heated plate is placed between
the tables, and the hydraulic. ram. put in motion, the plate will be held
between them. If all the four saws are put in motion, and each traversing
in the same direction, the four edges of the plate will be sawn or shaped on
two edges to the form indicated by the beds on the lower rectangular frame,
and the two ends of the plate will be shaped to the form indicated by the copy
or former which governs the transverse slides of the two upper saws.
We
prefer to act on the plates while hot from the rolls, but they may be reheated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Fernie and George Taylor in the Great Seal Patent
Office on the 30th May 1864.

:
NOW KNOW YE, that we, the said John Fernie and George Taylor,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, reference being had to the Drawing
hereunto annexed, that is to say :-
The edges of boiler and other like plates are generally ragged and uneven.
when they leave the rolls, and the object of our Invention is to finish and.
shape the edges while the plates are still hot, to the exact or nearly exact
shape and dimensions required for the use to which they are destined.
Our Invention consists of a machine constructed and acting in manner here-
after described. On the four corners of a rectangular metal frame we fix four
pillars. The upper ends of these pillars support a similar rectangular frame,.
and all are bolted together. On the lower frame are fitted two movable
beds, which can be placed slightly deviating from the parallel if required;
each of these beds carries a sliding saddle, moved by a screw or other con-
venient means: On the upper side of these saddles is cast an upright, upon
which another saddle is fitted capable of being moved vertically by screw and
bevil gearing. Each of these vertical saddles carries an oscillating headstock
provided with suitable journals, into which is fitted a spindle; on one end of
this spindle there is a turbine or Barker's mill, which is actuated by high-
pressure steam, and on the other end. a saw or cutting wheel suitable for
cutting heated iron is mounted. Two of these saws and their apparatus are
mounted upon the beds which are carried upon the lower rectangular frame.
Two movable beds of similar construction to the lower beds are connected to

page_text: with a ram.
and carried by the upper rectangular frame. These movable beds are supplied
with similar saddles, beadstocks, spindles, saws, or cutting wheels, and motive
gear to those already described, but have in addition a transverse slide fitted
to the saddle. This transverse slide is governed by a copy ".or "former,"
which will cause the saw to traverse slightly from a straight line when required.
In the centre of the rectangular frame we fix a hydraulic cylinder provided
On the top of this ram a table of cast iron is mounted, and over
this table, firmly fixed to the upper rectangular frame, is a table of similar
shape and construction to the lower one. If a heated plate is placed between
the tables, and the bydraulic ram put in motion, the plate will be held
between them. If all the four saws are put in motion, and each traversing in
the same direction, the four edges of the plate will be sawn or shaped on two
edges to the form indicated by the beds on the lower rectangular frame, and
the two ends of the plate will be shaped to the form indicated by the copy or
former, which governs the transverse slides of the two upper saws. We prefer
to act on the plates while hot from the rolls, but they may be reheated.
The accompanying Drawing is an elevation of a machine for shaping the
edges of boiler and other plates constructed according to our Invention.
a, a, is a rectangular metal frame, on the four corners of which we fix four
pillars 6, 6; the upper ends of the pillars b, b, support a similar rectangular
frame c, c, and all are bolted together; d, d, are two movable beds fitted to the
frame a, a; they may be placed slightly deviating from the parallel if required.
Each bed d carries a sliding saddle e, moved by a screw or otherwise. An
upright is cast on the upper side of each saddle e, as shewn, upon which
another saddle fis fitted, capable of being moved vertically by screw and
bevil gearing as before stated. Each saddle f carries an oscillating headstock g
provided with journals, into which a spindle is fitted; on one end of this spindle
there is a turbine or Barker's mill h, actuated by high-pressure steam, and on
the other end a saw or cutting wheel i, suitable for cutting heated iron, is
mounted. Two of these saws i, i, and their apparatus are mounted upon the
beds d, d, carried by the lower frame a, a. Two movable beds k, k, of similar
construction to the beds d, d, are connected to and carried by the upper
frame c, c. These beds are, as before mentioned, supplied with similar saddles,
headstocks, spindles, saws, or cutting wheels, and motive gear to the beds d, d;
1, 1, is one of the saddles of the upper beds; m, m, is a transverse slide fitted
to the saddles, and governed by a "copy" or "former," which will cause
the saw to traverse slightly from a straight line when required; n is a
hydraulic cylinder fixed in the centre of the machine, and provided with a
and
ram n'; o is a cast-iron table, mounted on the top of the ram;
P
is

page_text: a similar table fixed to the upper rectangular frame c, c.
The heated plate 9,
the edges of which are to be shaped, is placed between the tables o, p, and is
held firmly between them by the ram n', which is caused to rise for that
purpose. If all the four saws are put in motion, two edges of the plate q will
be sawn or shaped to the form indicated by the lower beds d, d, and the other
two edges to the form indicated by the copy or former which governs the
transverse slide m of the two upper saws.
In some cases we construct our machinery in two separate parts or machines,
each carrying two saws or cutting wheels, but we prefer the arrangement first
described.
Instead of being driven by a turbine or Barker's mill as before mentioned,
the saws or cutting wheels may be driven by belts, bands, or otherwise.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim, constructing
machinery, substantially in manner herein-before described and illustrated in
the accompanying Drawing, for shaping the edges of boiler and other plates,
when heated, to the exact or nearly exact shape and dimensions required.
In witness whereof, I, the said George Taylor, have hereunto set my
hand and seal, this Twenty-eighth day of May, One thousand eight
hundred and sixty-four.
GEORGE TAYLOR. (L.S.)
