Year: 1877

page_text: LETTERS PATENT to Anthon Steenberg, Patent Agent, of Copenhagen, Denmark,
for the Invention of "AN IMPROVED SAFETY PIN." A communication from
Thorvald Thorson and Holger Petersen, persons resident at Copenhagen,
Denmark.
Sealed the 16th November 1877, and dated the 18th May 1877.
PROVISIONAL SPECIFICATION left by the said Anthon Steenberg at the
Office of the Commissioners of Patents on the 18th May 1877.
ANTHON STEENBERG, Patent Agent, of Copenhagen, Denmark. "AN IMPROVED
SAFETY PIN." [A communication by Thorvald Thorson and Holger Petersen, residing
at Copenhagen, Denmark.]
The object of this Invention is to obtain a pin which can gather two separated
articles conveniently and quickly, and in such manner that the pin cannot loosen
itself, and at the same time it is closed in such a manner that the points of the pin
cannot tear when they are loose in the clothes wherein they are placed.
The form of these improved pins somewhat resembles that of a hair pin, that is
to say, it has two legs formed of a single piece of wire, but it is coiled spirally at its
head to form an elastic joint on which the legs can open and close, and it may be
einployed as a hair pin or in many other ways. It is provided at one end with a
lock that is fastened to one leg and in which the other leg is enclosed by the
points.
The lock consists of a small bent or double plate whose two sides leave a little
interval that corresponds with the thickness of the pin. On the one side of the
lock is a small aperture through which the point of one leg of the pin enters when
the said pin is closed.
As above mentioned, the said pin can be used as a hair pin, but in order to pre-
vent that the coiled end shall not be involved or caught in the hair, it is covered on
both sides with a small plate or shield.
The said pin can be ornamented in different manners and may be formed of any
suitable material.

an Order of the Lord Chancellor filed by the said Anthon Steenberg in the
Great Seal Patent Office on the 18th December 1877.
ANTHON STEENBERG, Patent Agent, of Copenhagen, Denmark. "AN IMPROVED
SAFETY PIN." A communication by Thorvald Thorson and Holger Petersen, persons
resident at Copenhagen, Denmark.
The object of this Invention is to furnish a device or pin which can be used to
gather and secure two separate articles conveniently and quickly, and in such a
manner that the said pin cannot become accidentally loose, and at the same time it
is closed in such a manner that the points of the pin cannot tear like ordinary pins
when they are loosened in the clothes or other articles wherein they are placed.
In the accompanying Drawing Figure 1 shews my improved safety pin open;
Figures 2 and 3 show the same closed.
The form of this improved safety pin, as shewn, somewhat resembles that of an
ordinary hair pin, that is to say, it has two legs formed of a single piece of wire,
but coiled spirally at its head or bend to give elasticity to the said legs, and it may
be employed as a hair pin or in many other ways. It is provided with a lock a,
that is fastened to one leg b, and in which the extremity or point of the other leg c
is enclosed.
The lock a consists of a small bent or double plate, whose two sides
have between them a slight space that corresponds with the thickness of the pin;
on one side of the lock is a notch or aperture d, through which the point of one
leg of the pin enters when the said pin is to be closed.
As above-mentioned the said device may be used as a hair pin, but in this case,
in order that the coiled end or head shall not be involved or entangled in the hair,
it is covered on both sides with a small plate or shell c, as shown in Fig. 3.
The said pin may be formed of any suitable material and finished or ornamented
as desired.
Having thus fully described the said Invention, and the manner of performing the
same, I wish it to be understood that I claim, the improved safety pin, consisting of
the single piece of wire, coiled spirally, and extended to form the legs, in combi-
nation with the lock for securing and protecting the points of the said legs, and
with or without the cover or shell on the head as above described.
In witness whereof, I, the said Anthon Steenberg, have hereunto set my hand
and seal, this Fifteenth day of November, in the year of our Lord One
thousand eight hundred and seventy-seven.
ANTHON STEENBERG. (L.S.)
