Proprietor of the Scandinavian Patent Office, under the Firm of L. A. Groth
and Co., 97, Finsbury Pavement, London, and 20, Forhaabningsholms Allee,
Copenhagen, for an Invention of "A NEW OR IMPROVED CONSTRUCTION
OF SAFETY PINS." A communication from abroad by Joseph Levi, of New
York City, in the County and State of New York, United States of America.
PROVISIONAL SPECIFICATION loft by the said Lorentz Albert Groth at the
Office of the Commissioners of Patonts on the 18th June 1881.
LORENTZ ALBERT GROTH, K.G.V., Civil Engineer and Proprietor of the
Scandinavian Patent Office, under the Firm of L A. Groth & Co., 97, Finsbury
Pavement, London, and 20, Forhaabningsholms Alleo, Copenhagen. "A NEW
OR IMPROVED CONSTRUCTION OF SAFETY PINS." A communication from abroad
by Joseph Levi, of New York City, in the County and State of New York, United
States of America.
This Invention refers to a new or improved construction of safety pins.
This safety pin consists of two different parts, one forming a common pin and
the other a spring cap to be placed on the pin after it has been thread through
the cloth.
The spring cap consists simply of a spiral spring made from wire and of a size to
suit the pin. One end of the spring cap is open, and the other provided with a
top or head.
When the safety pin is to be used the pin is thread through the stuff, after
which the spring cap with a little turning is fastened to the pin, thus giving
safety enough to prevent any of the parts of the pin from being lost.
Both parts of the safety pin can, if desired, be connected with each other.

LORENTZ ALBERT GROTH, K.G.V., Civil Engineer and Proprietor of the
Scandinavian Patent Office, under the Firm of L. A. Groth & Co., 97, Finsbury
Pavement, London, and 20, Forhanbningsholms Allee, Copenhagon, "A NEW
OR IMPROVED CONSTRUCTION OF SAFETY PINS." A communication from abroad
by Joseph Levi, of New York City, in the County and State of New York, United
States of America.
This Invention refers to a new or improved construction of safety pin. The
safety pin consists of two different parts, one forming a common pin and the other
a spring cap to be placed on the pin after it has been thread through the cloth.
Fig. 1 is a sectional view of the complete pin.
Fig. 2 is a common pin.
Fig. 3 is the spring cap; Fig. 4 is the pin as connected,
The spring cap B consists simply of a spiral spring C made from wire and of
a size to suit the pin.
One end of the spring cap B is open, and the other provided with a top or
head D.
When the safety pin is to be used the pin is thread through the stuff, after
which the spring cap B with a little turning is fastened to the pin, thus giving
safety enough to prevent any of the parts of the pin from being lost.
Both parts of the safety pin can, if desired, be connected to each other by means
of chains or other similar connections.
Having now described the nature of the said Invention and the manner in
which the same is to be performed, I would have it understood that what I
claim is,-
The spring cap B consisting of a spiral spring C with a top or head D arranged
and fitted to a common pin, as above described and illustrated in the Drawings
hereto annexed and for the purpose herein set forth.
In witness whereof, I, the said Lorentz Albert Groth, have hereunto set my
hand and seal, this Fourteenth day of December, in the year of our Lord
One thousand eight hundred and eighty one.
