IMPROVEMENTS IN THE MANUFACTURE OF HORSE NAILS
Year: 1881

page_text: LETTERS PATENT to John Albert Huggett, of 21, Finborough Road, Kensington,
in the County of Middlesex, for an Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF HORSE NAILS."
PROVISIONAL SPECIFICATION left by the said John Albert Huggett at the
Office of the Commissioners of Patents on the 29th November 1881.
JOHN ALBERT HUGGETT, of 21, Finborough Road, Kensington, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF HORSE NAILS."
This Invention has for its object improvements in the manufacture of horse
nails.
For this purpose I first prepare by hot rolling a mild steel bar, such as is
described in the Specification of my Patent, No. 1789, in the year 1877, of a
sectional form corresponding to two nails laid point to point and grooved along the
centre to give the proper bevil to the points. In place however of proceeding to
shear alternate pieces, nails, and waste from this bar, as is described in the said
Specification, I first slit or divide the bar along the centre by means of roller
shears, and from the lengths thus obtained I punch out pieces, forming nails by
means of a punch and bolster of corresponding shape.

by the said John Albert Huggett in the Great Seal Patent Office on the
27th May 1882.
JOHN ALBERT HUGGETT, of 21, Finborough Road, Kensington, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF HORSE NAILS."
This Invention has for its object improvements in the manufacture of horse
nails.
For this purpose I first prepare by hot rolling a mild steel bar, such as is
described in the Specification of my Patent, No. 1789, in the year 1877, of a
sectional form corresponding to two nails laid point to point and grooved along
the centre to give the proper bevil to the points. In place however of proceeding
to shear alternate pieces, nails, and waste from this bar, as is described in the said
Specification, I first slit or divide the bar along the centre by means of roller
shears, and from the lengths thus obtained I punch out pieces, forming nails by
means of a punch and bolster of corresponding shape.
In order that my said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a transverse section of the steel nail bar in the form in
which it is rolled; Figure 2 is a similar view of one of the parts into which the
bar is divided by slitting the bar, Figure 1, along the centre; Figure 3 is a side
elevation of the bolster and punch used in punching out the nail blauks; Figure 4
is a plan of the boister; and Figure 5 is an end view of the same.
The bolster, for convenience of manufacture and hardening, is made in three
pieces fitted and pinned together, as shewn, and it is received into a cavity which
it just fits in the bed of the machine. The position in which the split nail bar is
laid upon the bolster is indicated by the dotted lines in Figure 3. The hole on
the face of the bolster corresponds to the form of the nail blank to be produced,
but the hole is tapered or enlarged in passing downwards from the mouth, so that
the blanks when punched out from the bar may fall freely away through the
bolster and the bed on which the bolster is supported. The lower part of the
punch is exactly fitted to the hole in the bolster, and its face is inclined so that it
commences to operate against the nail bar upon the thicker or head side.
The punch is mounted in the machine in the usual way, and adjusted at each
descent to enter truly into the hole in the bolster, forcing before it a piece of the
nail bar which forms a nail blank. The nail blanks are finished by the operations
described in the Specification of my Patent, No. 2024, in the year 1879, that is to
say, by passing them sideways between suitably formed rollers, and at a subsequent
operation clipping the points by means of V form clipping cutters.
Having thus described the nature of my said Invention and the manner of
performing the same, I would have it understood that I claim the manufacture of
horse nails, substantially as herein described.
In witness whereof, I, the said John Albert Huggett, have hereunto set my
hand and seal, this Twenty fourth day of May, One thousand eight
hundred and eighty two.
