in the County of Surrey, for the Invention of "IMPROVEMENTS IN
MANUFACTURE OF WROUGHT NAILS."
THE
Sealed the 21st December 1876, and dated the 10th October 1870.
PROVISIONAL SPECIFICATION left by the said John Albert Huggett at the
Office of the Commissioners of Patents on the 10th October 1876.
JOHN ALBERT HUGGETT, of No. 12, Ferndale Road, Clapham, in the County of
Surrey. IMPROVEMENTS IN THE MANUFACTURE OF WROUGHT NAILS."
"
This Invention has for its object improvements in the manufacture of wrought
nails.
There is at the present time in the market and made in large quantities a class of
nails such as is shown in the Drawing annexed, Figure 1 being a side view, and
Figure 2 an edge view of the nail, and Figure 3 a plan or top view of the head.
The nail is, as will be seen, parallel on the side, and taper on the edge, and it has
a rose head overhanging on all sides the stem of the nail. Nails of this sort are at
present made by rolling the metal in a nail rod, cutting off from the rod lengths
suitable to form nails, and passing these lengths between rollers to give the taper
towards one end for the point. Afterwards the blanks are headed at the other end.
Now according to my Invention I produce this nail in place of from iron, the
material hertofore employed, from a soft homogeneous or cast steel; this material
I roll into bars of a section such as is shown at Figure 4; a side view also of the
bar is shown at Figure 5. I cut the bar transversely into strips, as is indicated by
the dotted lines in Figure 5, and in order to prevent the strips being deformed in
the operation of shearing I cause the end of the bar on the opposite side to the
shearing blade to be supported by a spring presser.
In place of the bar being rolled to the section shown at Figure 4 it may be rolled
to a section corresponding to two such bars placed together edge to edge, so that
cach strip cut off from it then makes two nail blanks joined together point to
point.
In order to finish the heads of the nail blanks the upper end of the blank is held
between a pair of dies which close upon it, and whilst so held it receives a blow

page_text: from a heading tool, which drives the metal in the bulb upon the blank into the
cavities of the dies, which correspond in form to the head it is desired to produce.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Albert Huggett in the Great Seal Patent Office on the 9th
April 1877.
JOHN ALBERT HUGGETT, of No. 12, Ferndale Road, Clapham, in the County of
Surrey. "IMPROVEMENTS IN THE MANUFACTURE OF WROUGHT NAILS."
This Invention has for its object improvements in the manufacture of wrought
nails.
There is at the present time in the market and made in large quantities a class
of nails such as is shown in the Drawing annexed, Figure I being a side view, and
Figure 2 an edge view of the nail, and Figure 3, a plan or top view of the head.
The nail is, as will be seen, parallel on the side and taper on the edge, and it has
a rose head overhanging on all sides the stem of the nail. Nails of this sort are at
present made by rolling the metal into a nail rod, cutting off from the rod lengths
suitable to form nails, and passing these lengths between rollers to give the taper
towards one end for the point. Afterwards the blanks are headed at the other end.
Now according to my Invention I produce this nail in place of from wrought iron,
the material heretofore employed, from a soft homogeneous or cast steel or steely
iron. A suitable metal is produced by the Siemens-Martin process, and also is made
in Sweden by the Bessemer process from charcoal iron; this material I roll into
bars of a section such as is shown at Figure 4; a side view also of the bar is shown
at Figure 5. I cut the bar transversely into strips, as is indicated by the dotted
lines in Figure 5, and in order to prevent the strips being deformed in the operation
of shearing I cause the end of the bar on the opposite side to the shearing blade to
be supported by a spring presser.
In place of the bar being rolled to the section shewn at Figure 4 it may be rolled
to a section corresponding to two such bars placed together edge to edge, so that
each strip cut off from it then makes two nail blanks joined together point to point,
or two cutters may be employed, one slightly preceding the other, and cutting off
separate nails.
In order to finish the heads of the nail blanks I employ a heading machine of
well-known construction; the upper end of the blank is held between a pair of dies,
which close upon it, and whilst so held it receives a blow from a heading tool, which
drives the metal in the bulb upon the blank into the cavities of the dies, which cor-
respond in form to the head it is desired to produce.
What I claim is, the manufacture of nails such as the Drawing represents from
soft, homogeneous, or cast metal by rolling bars of the section described, shearing
blanks from such bars, and heading the blanks, all substantially as herein
described.
In witness whereof, I, the said John Albert Huggett, have hereunto set my
hand and seal, this Thirty-first day of March, in the year of our Lord, One
thousand eight hundred and seventy-seven.
