page_text: LETTERS PATENT to William Gorse, of Birmingham, in the County
of Warwick, Machinist, for the Invention of "IMPROVEMENTS "IN
THE PREPARATION OF STRIPS OF IRON AND STEEL FOR THE MANUFACTURE
OF FLAT-POINTED CUT NAILS."
Sealed the 31st July 1868, and dated the 21st April 1868.
PROVISIONAL SPECIFICATION left by the said William Gorse at
the Office of the Commissioners of Patents, with his Petition, on
the 21st April 1868.
I, WILLIAM GORSE, of Birmingham, in the County of Warwick,
Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE PREPARATION OF STRIPS OF IRON AND STEEL FOR THE
MANUFACTURE OF FLAT-POINTED CUT NAILS," to be as follows:-
In preparing the said strips according to my Invention I take bars
of Swedish iron, or of the kind of steel called Bessemer homogeneous
metal, or other kinds of iron or steel haying little or no fibre, and I
roll the said bars into strips of a taper or wedge shape in cross section,
that is, thick at one edge and thin at the other edge; or I roll compound

page_text: strips of the size and figure of two or more of the said taper or wedge-
shaped strips joined together, either at the thick edges or at the thin
edges, or the thin edge of one joined to the thick edge of the other.
These compound strips when divided longitudinally by a slitting mill or
otherwise form strips of the first-described kind. When the said taper or
wedge-shaped strips are cut up transversely by the ordinary nail-cutting
machine they form flat-pointed nails. Owing to the absence of grain
or fibre in the iron or steel employed nails so made are very strong.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Gorse in the Great Seal Patent Office on
the 13th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GORSE, of Birmingham, in the County of Warwick, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of April, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Gorse, Her special licence that
I, the said William Gorse, my executors, administrators, and assigns, or
such others as I, the said William Gorse, 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 "IMPROVEMENTS IN THE PREPARATION
OF STRIPS OF IRON AND STEEL FOR THE MANUFACTURE OF FLAT-POINTED CUT
NAILS," upon the condition (amongst others) that I, the said William
Gorse, 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.

page_text: NOW KNOW YE, that I, the said William Gorse, do hereby declare
the nature of the 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, that is to say :-
In preparing the said strips according to my Invention I take bars
of Swedish iron, or of the kind of steel called Bessemer homogeneous
metal, or other kinds of iron or steel having little or no fibre, and I
roll the said bar into strips of a taper or wedge shape in cross section,
that is, thick at one edge and thin at the other edge; or I roll compound
strips of the size and figure of two or more of the said taper or wedge-
shaped strips joined together, either at the thick edges or at the thin
edges, or the thin edge of one joined to the thick edge of the other.
These compound strips when divided longitudinally by a slitting mill,
or otherwise, form strips of the first-described kind. When the said
taper or wedge-shaped strips are cut up transversely by the ordinary
nail-cutting machine they form blanks, which are afterwards made
into flat-pointed nails. Owing to the absence of grain or fibre in the
iron or steel employed nails so made are very strong.
.
Figure 1 represents in plan and cross section a strip of iron or steel
prepared or rolled of a taper or wedge shape in cross section from a
bar of Swedish iron or steel or Bessemer homogeneous metal according
to my Invention for the manufacture of flat-pointed cut nails. By an
examination of the cross section marked a the taper figure of the
strip will be readily scen. By cutting the strip, Figure 1, transversly
at the dotted lines by an ordinary nail-cutting machine blanks are
formed, from which flat-pointed nails are to be made. Figure 14
represents is front and edge view a blank cut from the strip, Figure 1;
and Figure 1 represents in front and edge view a flat-pointed nail
made from the blank, Figure 1^, the heading of the blanks to form
nails being effected in the, ordinary way. Nails thus made are very
strong, owing to the absence of fibre in the iron or steel from which
the wedge-shaped strip was made.
Figure 2 represents in plan and cross section, a compound strip of
the size and figure of two of the strips, Figure 1, that is, the strip,
Figure, 2, consists of two wedge-shaped strips b, c, joined together at
their thick ends. By slitting the compound strip lengthwise at the
dotted line d by means of a slitting mill, or otherwise, two strips b, c,
nearly similar to that represented in Figure 1 are produced.

page_text: Figure 3 represents in plan and section another compound strip
prepared according to my Invention, the wedge-shaped strips e, f, in
this case being joined together at their thin edges. This compound
strip is divided longitudinally at the dotted line 9, so as to form two
strips, as described with respect to Figure 2. Instead of joining the
compound strip at the thin or thick edges of the wedge-shaped strips,
as in Figures 2 and 3, compound strips may be prepared according to
my Invention in which the thin edge of one strip is joined to the
thick edge of the other strip; and instead of preparing compound
strips of the figure of two single wedge-shaped strips only, the said
compound strips may be prepared of the figure of more than two single
wedge-shaped strips; I prefer, however, to carry my Invention into
effect in the manner represented in the Drawing. Instead of making
the compound strips flat on one side and bevilled on the other side
the said strips may be bevilled on both sides, as illustrated at 1,
Figure 3. The other compound strips described and represented may
also be similarly bevilled. on both sides. The blanks cut from strips
bevilled on both sides exactly resemble the blanks cut from the single
strip, Figure 1.
I roll the strips or compound strips by passing them through the
rolls lengthwise, or in the direction in which hoop strips are rolled.
In the Drawing the arrows indicate the direction in which the strips
are passed through the rolls. The rolls which I employ for rolling or
preparing the strips or compound strips from bars of Swedish iron or
Bessemer homogeneous metal, or other kinds of iron or steel having
little or no fibre are constructed in the ordinary way, and any competent
roll turner will be able from the sections of the strips herein described
and represented to construct the said rolls.
Having now described the nature of my Invention, and the manner
in which the same is to be performed, I wish it to be understood that
I do not limit myself to the precise details herein described and
illustrated, as the same may be varied without departing from the
nature of my Invention; but I claim as my Invention, the improve-
ments in the preparation of strips of iron and steel for the manufacture
of flat-pointed nails, herein-before described and illustrated in the
accompanying Drawing, that is to say, rolling strips of iron or steel
of a taper or wedge shape in cross section, or of the figure of two or
more of the said taper or wedge-shaped strips from bars of Swedish

page_text: iron, or of the kind of steel called Bessemer homogeneous metal, or
other kinds of iron or steel having little or no fibre, the said strips
being formed by being passed through the rolls lengthways, and cutting
up the said strips transversely to form flat-pointed nails, as described
p and illustrated.
In witness whereof, I, the said William Gorse, have hereunto set
my hand and seal, this Third day of August, in the year of our
being formed by being passed through the rolls lengthways, and cutting
up the said strips transversely to form flat-pointed nails, as described
and illustrated.
In witness whereof, I, the said William Gorse, have hereunto set
hand and seal, this Third day of August, in the year of our
Lord One thousand eight hundred and sixty-eight.
