IMPROVEMENTS IN FOLDING EYE GLASSES OR PINCE-NEZ
Year: 1884

page_text: I, NICOLAS KORSHUNOFF, Civil Engineer 37, Rue de Chazelles, Paris do hereby
declare the nature of my Invention for IMPROVEMENTS IN FOLDING EYE GLASSES
OR PINCE-NEZ to be as follows:-
My Invention is a new style of spectacles named "Triple Fix" representing the
numerous advantages from the different systems analogous at present in use.
The holders of my spectacles "Triple Fix" carries the pressure on either side of
the nose up and around the inner corners of the eyes and carries it without
interruption until about the middle of the arc of the eye-brows, so that the
pressure on the nose is distributed uniformly in this manner for about one inch
and a half on either side of the nose.
The holders may be:
:
1st Immovably fixed and flat.
2nd
do
do and round or oval.
3rd Immovably fixed at both ends.
4th Moveable and flat, round or other form.
The holders of these spectacles can be made of the same materials generally used
in the mountings of spectacles, and can be covered with tortoiseshell, leather &c. or
any other material, & if desired can be coloured exactly like the complexion.
The spectacles described as above are so characterised for their simplicity and
remarkable fixity that for preparing spectacles such as above must be remembered
as a general rule the measure of the distance between the pupils of the eyes which
distance can easily be measured along the line of the eye-brows & cut the shape
of the arc of the brow and the thickness of the bridge of the nose. With this
measure the spectacles will fit at once and the centre of the glasses will always
be directly in front of the pupils of the eyes, thereby greatly preserving the eye
sight.
The principial advantages are as follows:
1st These spectacles will be firmly fixed in their proper place in whatever position
the person's head may be in.,
2nd The focus of the glasses is always placed exactly in front of the pupils of
the eyes.
3rd As the pressure on the face is distributed over a length of three inches, it is
so equalised as scarcely to be felt and leaves no feeling or mark of irritation.
In a word these spectacles assist greatly in preserving the eye sight.

page_text: I NICOLAS KORSHUNOFF, Civil Engineer 37, Rue de Chazelles, Paris, do hereby
declare the nature of my Invention for IMPROVEMENTS IN FOLDING EYE GLASSES
OR PINCE-NEZ, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The present Invention is a new style of spectacles named "Triple Fix" repre-
senting the numerous advantages from the different systems analogous at present
in use.
"
The holders of my spectacles "Triple Fix" carries the pressure on either side
of the nose up and around the inner corner of the eyes and carries it without
interruption until about the middle of the arc of the eye-brow, so that the
pressure on the nose is distributed uniformly in this manner for about one inch
and a half on either side of the nose.
The holders may be :'
1st Immovably fixed and flat.
2nd
do
do and round or oval.
3rd
do
do at both ends.
4th Moveable and flat, round or other form.
The spectacles of the first three sorts will be sold in special boxes convenient to
be carried in the pocket. The other kinds of spectacles which are described will
be closed in the ordinary manner therefore the holders of them will be moveable
from the usual angle so as to be level with the surface of the glasses when folded.
The holders of these spectacles can be made of the same material generally used in
the mountings of spectacles and can be covered with tortoiseshell, leather &c., or
any other material, and if desired can be coloured exactly like the complexion.
The spectacles described as above are so characterised for their simplicity and
remarkable fixity that I have selected only four specimens showing six Figures!
1 Fig. This is a plane view with flat moveable or fixed holders.
2nd Fig. Is a top view of the same showing the exactly required position of the
holders.
3rd Fig. Represents the holders fixed at both ends, giving a plane view.
4th Fig. Gives a top view of the same.
5th Fig. Is a plane view with the holders joined at one end to the glass and
except the bridge no other mountings are.required.
6th Fig. Gives a plane view in which the holders are moveable and are joined
with the bridge on the line of the great axle of the oval of the glasses. With a
small spring attached to the holders they can be preserved in the necessary angle.
When folding the glasses for closing the springs permit the holders to lie flat on a
level with the surface of the glasses.
Having now explained the nature of my Invention I do not limit myself in
materials, form, and the manner in fixing the holders to the mountings of the
spectacles, as all mountings holders, or their accessories can be easily varied as
required. Spectacles strong, light, very light, elegant, aesthetic or highly aesthetic,
for example:
The aesthetic can be made from two glasses of crystal stones with the bridge
and holders covered with silk of the colour of the skin. The outer edges of the
.glasses must be finely grooved to keep the fingers from slipping when adjusting the
spectacles on the face. Another kind can be made with the mountings and holders
of tortoiseshell.
For preparing spectacles such as above there must be remembered as a general
rule the measure of the distance between the pupils of the eyes which distance can

the brow and the thickness of the bridge of the nose. With this measure the
spectacles will fit at once and the centre of the glasses will always be directly in
front of the pupils of the eyes thereby greatly preserving the eyesight.
The principal advantages are as follows:
1st The spectacles will be firmly fixed in their proper place in whatever position
the person's head may be."
2nd The focus of the glasses is always directly placed in front of the pupils of
the eyes.
3rd The pressure on the face of the person is so èqualised as scarcely to be felt
and leaves no feeling or mark of irritation.
In a word these spectacles assist greatly in preserving the eyesight.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
'
1. The holders of the spectacles which grip without interruption about one inch
and a half on either side of the nose substantially as described and represented by
the specimens on the Drawings.
