page_text: LETTERS PATENT to Peter Purdie, of Glasgow, in the County of Lanark,
North Britain, for the Invention of "NEW OR IMPROVED NAIls, Budds,
SPRIGS, AND RIVETS, AND IMPROVEMENTS IN THE MEANS OR MECHANISM
EMPLOYED FOR ManufacturING THE SAME.'
"
Sealed the 19th January 1875, and dated the 27th November 1874.
PROVISIONAL SPECIFICATION left by the said Peter Purdie at the
Office of the Commissioners of Patents, with his Petition, on the
27th November 1874.
I, PETER PURDIE, of Glasgow, in the County of Lanark, North
Britain, do hereby declare the nature of the said Invention for "New
OR IMPROVED NAILS, BUDDS, SPRIGS, AND RIVETS, AND IMPROVEMENTS IN THE
MEANS OR MECHANISM EMPLOYED FOR MANUFACTURING THE SAME," to be as
follows, that is to say :—
The first part of this Invention, which relates to new or improved nails,
budds, and sprigs, has reference to such as are or may be used in
carpentry, in the manufacture of boots and shoes, in fixing shoes on
horses' feet, or for other purposes wherein nails, budds, and sprigs are

page_text: employed. And the Invention also relates to forming or constructing.
rivets for shipbuilding or other purposes after the manner of the improved
nails, budds, or sprigs, and by the mechanism herein-after described as
constituting the second part of this Invention.
The objects of the Invention are to reduce the weight of metal con-
stituting the improved nails, budds, sprigs, and rivets, to prevent the
splitting of the materials into which they are driven, and to enable a
greater number to be driven into any given area or surface. These
objects are effected by constructing the nails, budds, sprigs, and rivets of
a taper form and triangular in section, and they are or may be formed of
iron, steel, copper, brass, or tin.
The second part of the Invention, which relates to the means or
mechanism by which the improved nails, budds, sprigs, and rivets are
produced, consists of dies or revolving wheels, whose edges or peripheries
have taper triangular recesses in alternate directions cut into their
surfaces. These dies or revolving wheels being pressed or forced into or
upon the piece or bar of iron, steel, copper, brass, or tin from which the
nails, budds, sprigs, or rivets are to be made, at once cut or divide the
metal into nails, budds, sprigs, or rivets of the form or shape herein-
before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Purdie in the Great Seal Patent Office on
the 26th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
PURDIE, of Glasgow, in the County of Lanark, North Britain, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of November,
in the year of our Lord One thousand eight hundred and seventy-
four, in the 38th year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Peter Purdie, Her special
license that I, the said Peter Purdie, my executors, administrators, and
assigns, or such others as I, the said Peter Purdie, my executors, admi-
nistrators, or assigns, should at any time agree with, and no others,

page_text: 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 "NEW OR IMPROVED NAILS,
BUDDS, SPRIGS, AND RIVETS, AND IMPROVEMENTS IN THE MEANS OR MECHANISM
EMPLOYED FOR MANUFACTURING THE SAME," upon the condition (amongst
others) that I, the said Peter Purdie, by an instrument in writing
under my hand and seal, 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 Peter Purdie, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings,
and to the letters and figures marked thereon, that is to say:
-
The first part of my said Invention, which relates to improved nails,
budds, and sprigs, has reference to such as are or may be used in carpentry,
in the manufacture of boots and shoes, in fixing shoes on horses' feet, or
for other purposes wherein nails, budds, and sprigs are employed. The
Invention also relates to forming or constructing rivets for ship-
building or other purposes after the manner of the improved nails,
budds, and sprigs, and by the mechanism herein-after described as con-
stituting the second part of my said Invention. 0
The objects of the Invention are to reduce the weight of metal con-
stituting the improved nails, budds, sprigs, and rivets, to prevent the
splitting of the materials into which they are driven, and to enable a
greater number to be driven into any given area or space.
And in order that my said Invention may be properly understood, I
now proceed more particularly to set forth the system, mode, or manner
in or under which the same is or may be used or practically carried into
effect, reference being had to the annexed Sheet of Drawings, and to the
letters and figures marked thereon, that is to say :—
On the Sheet of Drawings hereunto appended Figures 1, 2, and 3
illustrate the system of constructing the improved nails, budds, sprigs,

page_text: and rivets in accordance with my said Invention, as shown more par-
ticularly at Figures 2 and 3, which arc respectively an elevation and
transverse section of a singe nail. The nails, budds, sprigs, and rivets are
constructed of a taper form and triangular in section. Such nails, budds,
sprigs, and rivets may be formed of iron, steel, copper, brass, or tin, as
desired, and they are cut, stamped, or pressed from sheets, pieces, or bars
of such metal in the manner illustrated at Figure 1 of the Drawings,
that is to say, with the heads a and points 6 of the nails, budds, sprigs,
or rivets in alternate directions.
The means or mechanism by which the improved nails, budds, sprigs,
and rivets are produced, and which constitutes the second part of my
said Invention, consists of revolving dies or wheels, in the periphery of
the upper one of which taper triangular recesses are cut in alternate
directions, as illustrated in part side elevation at Figure 4, and in front
elevation at Figure 5 of the Drawings. The piece or bar of iron, steel,
copper, brass, or tin from which the nails, budds, sprigs, or rivets are to
be made is passed in between the plain roller or wheel A. and the cutting
roller or wheel B, which is caused to rotate by suitable gearing, and being
pressed or forced into or upon the said piece or bar the roller or wheel B
at once cuts or divides the metal into nails, budds, sprigs, or rivets of the
form or shape herein-before described.
Instead of employing a revolving die or wheel a flat vertically
operating die or stamp, whose under surface is formed with taper
triangular recesses in the manner herein-before set forth, and as indi-
cated at Figure 6 of the Drawings, may be used to produce the improved
nails, budds, sprigs, or rivets.
In making nails, budds, sprigs, or rivets in accordance with my said
Invention from the harder metals, such as iron or steel, the pieces or
bars of such metal before being operated upon by the dies or wheels are
or may be heated, and when it is desired to form a projecting head upon
the nails, budds, sprigs, or rivets a recess is formed in the side of the die
or wheel at the wider end of each tapered triangular groove, as indicated.
at x, Figure 4, into which the metal is forced by the pressing action of
the die or wheel upon it, or projecting heads may be otherwise formed on
the said nails, budds, sprigs, and rivets if desired.
Having now described and particularly ascertained the nature of my
said Invention, and the system, mode, or manner in or under which the

page_text: same is or may be used or practically. carried into effect, I would observe
in conclusion that what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited
Letters Patent is,→
First. The new or improved nails, budds, sprigs, and rivets constructed
of a taper form and triangular in section, as herein-before described and
shewn on the appended Drawings.
Second. The revolving flat cutters or dies with peripheries and surfaces
constructed as shewn at Figures 4, 5, and 6 of the Drawings, and the
employment thereof in the production of nails, budds, sprigs, and rivets,
as herein-before described.
In witness whereof I, the said Peter Purdie, have hereunto set my
hand and seal, this Twenty-fifth day of May, One thousand
eight hundred and seventy-five.
