Year: 1881

page_text: LETTERS PATENT to George Klug, of Glasgow, in the County of Lanark,
North Britain, for an Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF FLAT HEADED TACKS, NAILS, DRAWING PINS, AND ANALOGOUS ARTICLES."
A communication from Carl Meier, of Berlin, in the Empire of Germany.
PROVISIONAL SPECIFICATION left by the said George Klug at the Office
of the Commissioners of Patents on the 12th August 1881.
GEORGE KLUG, of Glasgow, in the County of Lanark, North Britain. “IM-
PROVEMENTS IN THE MANUFACTURE OF FLAT HEADED TACKS, NAILS, DRAWING
PINS, AND ANALOGOUS ARTICLES." A communication from Carl Meier, of Berlin,
in the Empire of Germany.
This Invention, which relates to the manufacture of flat head tacks, upholsterer's,
and other nails, drawing pins, and analogous articles, consists in forming the head
and stem or point of such articles in one piece from suitable sheet metal discs or
metal plates, the metal to form the stem or point being taken out from the disc or
plate forming the head, and under this method of construction the tack, nail, or pin
may have one, two, or more stems or points.
In forming the articles according to this Invention, the stem or point, say, of a
drawing pin, is formed by punching or driving a suitable streak of the head out or
through and bending it downwards. The stem or point being thus roughly shaped
is or may be rounded and somewhat lengthened by rolling or squeesing around its
sides, and the whole is afterwards stamped, polished, and finished in such a manner
as to suit the purpose for which the article is to be used.
When the tack, nail, or pin is to be formed with two or more stems or points,
these are produced by punching or bending a corresponding number of streaks
outwards from the centre of the metal disc or plate towards its periphery, the roots
or bases of the stems or points being near or around the periphery of the head,
after which the whole is stamped, polished, and finished according to the purpose
for which the article is to be used.
The heads of the tacks, nails, or pins may be circular, oval, elliptical, square, or
of other suitable form, and the said tacks, nails, or pins may be electro plated,
either wholly or on the heads, or otherwise ornamented as desired.
By this means of constructing tacks, nails, pins, or analogous articles, the cost of
manufacture is cheapened; and an article more ornamental and durable is likewise
produced, and which in the case of drawing pins may be employed without danger
of the stem coming through the head and injuring the person using it.

the said George Klug in the Great Seal Patent Office on the 7th February
1882.
GEORGE KLUG, of Glasgow, in the County of Lanark, North Britain. "IM-
PROVEMENTS IN THE MANUFACTURE OF FLAT HEADED TACKS, NAILS, DRAWING
PINS, AND ANALOGOUS ARTICLES." A. communication from Carl Meier, of Berlin,
in the Empire of Germany..
The said Invention, which relates to the manufacture of drawing pins, thumb
tacks, and similar nails, consists in forming the head and stem or point of such
articles in one piece and from suitable steel or other sheet metal discs or plates, the
metal to form the stem or point being taken out from the disc or plate forming the
head. Under this method of construction the said articles may have one, two, or
more stems or points.
In manufacturing, say, a drawing pin or thumb tack according to this Invention,
the stem or point is formed by partially separating, punching, or driving out a
suitable streak of the head and bending it downwards. The stem or point being
thus roughly shaped is or may be rounded and somewhat lengthened by rolling or
squeezing around its sides, and the whole is afterwards stamped to the requisite
shape, polished, and finished in a manner suitable to the purpose for which the
article is to be used.
When the article is to be formed with two or more stems or points, these are
produced by punching or bending a. corresponding number of streaks outwards
from the centre of the metal disc or plate towards its periphery, the roots or
bases of the stems or points being near or around the periphery of the head, after
which the whole is stamped, polished, and finished according to the purpose for
which the article is to be used."
The heads of the drawing pins or nails may be circular, oval, elliptical, square,
or of other suitable form, and the said pins or nails may be electro plated, either
wholly or on the heads, to protect them from rust, or otherwise ornamented as
desired.
By this means of constructing drawing pins, thumb tacks, or similar nails, the
cost of manufacture is cheapened, and an article more durable and if desired_more
ornamental is produced, and which may be employed without danger of the stem
coming through the head and injuring the person using the article, or of the stem
and head coming apart in withdrawing the pin from the board.
In order that the said Invention may be clearly understood, I have hereunto
appended an explanatory Sheet of Drawings, on which Figure 1 illustrates in plan
and Figure 2 in vertical section the method of striking the stem or point 6 out
from the head a; Figure 3 is a sectional view of the pin when completed, drawn
at right angles to Figure 2, all of these Figures being on an enlarged scale.
Having now described and particularly ascertained the nature of the said
Invention, as communicated to me by the said Carl Meier, I would observe in
conclusion that what is considered to be novel and original, and therefore claimed as
the Invention secured to me by the hereinbefore in part recited Letters Patent
is,―
The improved drawing pins, thumb tacks, and similar nails hereinbefore
described, and wherein the head and stem or stems is or are constructed in one

page_text: piece, substantially as set forth and in part shown on the Drawings hereunto
annexed.
In witness whereof, I, the said George Klug, have hereunto set my hand and
seal, this Second day of February, in the year of our Lord One thousand
eight hundred and eighty two.
