Complete Specification Left, 3rd Nov., 1899-Accepted, 9th Dec., 1899
I, OTTO VON SAAL, of 22, Basinghall Street, in the City of London, Merchant,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements in folders, rigid clip folders and other
kinds of pince-nez or eyeglasses.
In pince-nez or eyeglasses as heretofore usually made the plaquettes, to hold
the glasses in position, are held against the bridge of the wearer's nose with a
pressure which is disagreeable and which often marks the nose.
Now, this invention has for its object to so construct such eyeglasses that they
can be securely held in position without the wearer experiencing the above men-
tioned unpleasant pressure upon his nose. To this end the plaquettes are made
of a flexible material such as a suitable spring strip of metal, the said strip being.
secured at each end to a rigid piece or frame attached to the frame of the
pince-nez. The outer face of each flexible strip, that is to say, the face which
comes into contact with the nose, can be covered with suitable material.
With this construction of plaquette the nose is securely gripped by the pince-
nez without any undue pressure as the flexible plaquette strips adapt themselves
to the shape of the nose to which they are applied.

I, OTTO VON SAAL, of 22, Basinghall Street, in the City of London, Merchant,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the fol-
lowing statement:-
-
This invention relates to improvements in folders, rigid clip folders and other
kinds of pince-nez or eyeglasses.
In pince-nez or eyeglasses as heretofore usually made the plaquettes, to hold
the glasses in position, are held against the bridge of the wearer's nose with a
pressure which is disagreeable and which often marks the nose.
Now, this invention has for its object to so construct such eyeglasses that they
can be securely held in position without the wearer experiencing the above men-
tioned unpleasant pressure upon his nose. To this end the plaquettes are made

page_text: of a flexible material such as a suitable spring strip of metal, the said strip being
secured at each end to a support piece or frame attached to the frame of the
pince-nez. The outer face of each flexible strip, that is to say, the face which
comes into contact with the nose, can be covered with suitable material.
With this construction of plaquette the nose is securely gripped by the pince-
nez without any undue pressure as the flexible plaquette strips adapt themselves
to the shape of the nose to which they are applied.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawing in which:-
Figure 1 is a front elevation drawn to an exaggerated scale of a pince-nez with
a rigid bridge having my improvements applied thereto :
Figure 2 is a section on the line 2-2 Figure 1:
Figure 3 is a view similar to Figure 1 shewing the improvements applied to a
pince-nez with a flexible bridge:
Figure 4 is a plan thereof; and
Figure 5 is a section on the line 5-5 Figure 3.
Referring first to Figures 1 and 2 is the frame of the pince-nez and b, b are
my flexible plaquettes, the said plaquettes being advantageously made of strips
of flexible material such as spring metal covered with layers of suitable material.
d. d are the support pieces which are secured to the frame of the pince-nez
and to which the ends of the flexible plaquettes are attached by suitable means,
such for example as the teeth e, e formed on the support pieces d, d and which
are bent round the ends of the plaquettes so as to clip them as clearly shewn in
the drawing.
In the arrangement illustrated in Figures 3, 4 and 5 the support pieces d, d
are secured at their lower ends only to the frame a of the pince-nez, their upper
ends & being slotted and arranged to slide on guide pieces e¹, e¹, formed upon the
upper part of the frame a, this being an ordinary method of mounting plaquettes
to obtain the necessary yield.
It will be seen that with this construction of pince-nez the flexible plaquettes
adapt themselves to the shape of the nose of the wearer thereby obviating the
unpleasant pressure which is necessary with eyeglasses as ordinarily constructed
to retain them upon the nose.
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. In pince-nez the employment of plaquettes made of a flexible material, sub-
stantially as hereinbefore described.
2. Plaquettes for pince-nez constructed substantially as hereinbefore described
and illustrated in the accompanying drawing.
3. Pince-nez having plaquettes constructed substantially as hereinbefore
described and illustrated in the accompanying drawing.
