Year: 1875

page_text: LETTERS PATENT to Franziscus Xaver Ferdinandus Пcilborn, of
Birmingham, in the County of Warwick, Jewellor, for the Inven-
tion of "A NEW OR IMPROVED SPRING EARRING."
Sealed the 28th September 1875, and dated the 12th April 1875.
PROVISIONAL SPECIFICATION left by the said Franziscus Xaver
Fordinandus Heilborn at the Office of the Commissioners of
Patents, with his Petition, on the 12th April 1875.
I, FRANZISCUS XAVER FERDINANDUS HELLBORN, of Birmingham, in
the County of Warwick, Jeweller, do hereby declare the nature of tho
said Invention for "A NEW OR IMPROVED SPRING EARRING," to be as
follows:-
My Invention consists of a new or improved spring carring, the parts
of which are constructed and arranged as herein-after described.
The said earring consists of two semi-elliptical plates hinged together.
When the half rings or plates are closed upon one another their free or
unconnected ends nearly meet, and the two parts in their closed position

page_text: form a nearly complete elliptical ring. On the free end of one half ring
or plate a pin or wire is fixed, which when the carring is in use passes
through the piercing in the lobe of the car. A flat spring on the inside
of one half ring or plate acting on a hecl on the other half ring or plate,
and near the joint of the carring, retains the jointed half rings or plates
in their open position, and also forcibly holds them in their closed
position.
The jointed half rings or plates when closed upon one another are not
opposite one another, but that half ring or plate which constitutes the
front of the carring is inclined to the other or back half ring. The 1
result of thus arranging the half rings or plates is to present to the eye
when the earring is worn both the outer side of the front half ring and
the greater part of the inner side of the back half ring. The outer sido
of the front half ring may be ornamented in any desired manner.
In using the carring the jointed half rings or plates are opened out on
their joint so as to separate thein, and the pin or wire at the unjointed
end of the back half ring is passed through the piercing in the lobe of
the ear.
The front half ring is then closed upon the back half ring, the
spring described holding them firmly together. When the half rings
are thus closed the pin or wire on the free end of the back half ring
(which has been passed through the car) bears against the free end of
the other or front half ring, and the carring is very firmly fastened to
the car.
To detach the carring it is only necessary to separate the two jointed

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRAN- 30
ZISCUS XAVER FERDINANDUS HEILBORN, of Birmingham, in the County
of Warwick, Jeweller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of April, in the year of

page_text: our Lord One thousand cight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Icr heirs and successors,
give and grant unto me, the said Franziscus Xaver Ferdinandus
Heilborn, Her special license that I, the said Franziscus Xaver Ferdi-
nandus Heilborn, my executors, administrators, and assigns, or such
others as I, the said Franziscus Xaver Ferdinandus Пeilborn, my
executors, administrators, and assigns, should at any time agree with,
and no others, 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 "A
NEW OR IMPROVED SPRING EARRING," upon the condition (amongst others)
that I, the said Franziscus Xaver Ferdinandus Пcilborn, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
"
NOW KNOW YE, that I, the said Franziscus Xaver Ferdinandus
Heilborn, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to
say:―
My Invention consists of a new or improved spring carring, the parts
of which are constructed and arranged as herein-after described
The said carring consists of two semi-elliptical plates hinged together.
When the half rings or plates are closed upon one another their free or
unconnected ends nearly meet, and the two parts in their closed position
form a nearly complete elliptical ring. On the free end of one half ring
or plate a pin or wire is fixed, which when the carring is in use passes
through the piercing in the lobe of the car. A flat spring on the inside
of one half ring or plate acting on a heel on the other half ring or
plate and near the joint of the carring retains the jointed half rings or
plates in their open position, and also forcibly holds them in their closed
position.
The jointed half rings or plates when closed upon one another are not
onnosite one another. but.that half ung or plate which constitutes the

page_text: front of the earring is inclined to the other or back half ring The result
of thus arranging the half rings or plates is to present to the eye when
the earring is worn both the outer side of the front half ring, and the
greater part of the inner side of the back half ring. The outer side of
the front half ring may be ornamented in any desired manner.
Figure 1 of the accompanying Drawing represents in side elevation,
Figure 2 in edge view, and Figure 3 in plan a spring carring constructed
according to my Invention, the two half rings or plates being in their
closed position.
Figure 4 represents the carring open ready to be fixed to the car; and
Figure 5 represents an inside clevation of the two halves or plates of the
earring, and exhibits the position of the spring on the back half, and the
heel on the front half of the carring.
The same letters of reference indicate the same parts in the several
Figures of the Drawing.
" is the front half ring or plate, and is the back half ring or plate,
the two parts a, b, being jointed together at c. When the two half rings
or plates are closed upon one another, as illustrated in Figures 1, 2, and
3, they form a nearly complete elliptical ring. d is the pin or wiro fixed
to the free end of the front half ring a, which wire dis passed through
the lobe of the car to secure the carring to the car. On the inside of the
back half ring b is a spring e, the curved end of which bears against a
heel on the front half ring a, as scen best in Figure 4. By means of the
spring e the jointed half rings a, b, are retained in their open position, as
represented in Figure 4, or forcibly held together in their closed position,
as represented in Figures 1, 2, and 3.
By an examination of Figures 1, 2, and 3 it will be seen that the
jointed half rings a, b, when closed are not opposite one another, the
front half ring a being inclined to the back half ring b. By this arrange-
ment of the half rings the carring when worn presents to the cyc both
the outer side of the front half ring a, and the greater part of the inner
side of the back half ring 6 (see Figure 2).
b
In using the carring the jointed half rings or plates a, b, are opened
out on their joint, so as to separate them, as illustrated in Figure 4, and
the pin or wire d at the unjomted end of the front half ring a is passed
through the piercing in the lobe of the car. The front half ring a is

page_text: then closed upon the back half ring b, the spring e holding them firmly
together. When the half rings à, b, arc thus closed the pin or wire d on
the free end of the front half ring a (which has been "passed through
the car) bears against the free end of the other or back half ring b,
and the carring is very firmly fastened to the car.
To detach the earring it is only necessary to separate the two jointed
plates or half rings a, b, by which motion the pin or wire d is withdrawn
from the lobe of the car.
The pair of earrings constructed according to my Invention are alike,
except that they are inclined differently, the carring for the left car
inclining in an opposite direction to that of the carring for the right car.
The carring represented in the Drawing is the left earring
Having now described the nature of my Invention, and the manner
in which the same is to be performed, I wish it to be understood that
I do not limit myself to the precise details hercin described and
illustrated, as the same may be varied without departing from the nature
of my Invention, but I claim as my Invention, the new or improved
spring carring, the parts of which are constructed and arranged and
used substantially as herein-before described and illustrated in the
accompanying Drawing.
In witness whereof, I, the said Franziscus Xaver Ferdinandus
Heilborn, have hereunto set my hand and scal, this Thirtieth
day of September, in the year of our Lord One thousand eight
hundred and seventy-five.
