Pincenez."
I, JULES COTTET, fils, of Morez, Departement du Jura, in the Republic
of France, Optician, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a novel method of construction of folding eyeglasses
by which plates or supports by which the glasses are held upon the nose are moved
automatically out of the way when the glasses are closed and are brought into
their proper position when the glasses are opened.
The glasses consist of two elliptical rings of the usual kind connected by a
flat flexible spring the ends of which are fixed to the rings, and which also carries
a rigid semicircle the ends of which terminate in hooks and move freely through
rings formed upon arms which carry the moveable pressure plates or supports.
These arms are pivotted and turn upon screws screwed into supports carried by the
inner sides of the elliptical rings of the glasses, so that the arms turn in directions
at right angles to the glasses, and their outer ends are fitted with screws which are
screwed into sockets attached to the pressure plates, which have a slight play
allowed them.
When the eyeglasses constructed as described are opened they carry with them
the supports to which the arms are pivotted, whilst the rings upon the arms are
brought and kept in the right position by the rigid semi-circle. The arms are
therefore, together with the pressure plates, moved into or out of the required
position without touching or coming in the way.

Improvements in Flexible Eye-glasses or "Pincenez.'
I, JULES COTTET, fils, of Morez, Departement du Jura, in the Republic of
France, Optician, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, and accompanying drawing, that is
to say :-

My invention relates to a novel method of construction of flexible eye-glasses
or piucenez," (or eye-glasses, the glasses of which are connected by a flexible
spring so that they can be brought together, or opened out and separated), the
plates or supports by which the glasses are held upon the nose being moved auto-
matically into their required positions, when the glasses are separated or brought
together, respectively.
The accompanying drawing is in illustration of my invention, Figure 1 being a
front elevation of a pair of the improved eye-glasses; Figure 2 a similar view, of

page_text: the mechanism upon a much larger scale; Figure 3 a plan of Figure 2, showing
in dotted lines the position of the parts when the glasses have been opened or
separated, Figure 4 is a front view of a somewhat modified form of the improved
eye-glasses.
The glasses consist of two elliptical lens rings, or frames, a, of the usual kind,
connected (in the form shown in Figure 4) by a flat flexible spring c¹, the ends of
which are fixed to the rings by supports at b. In Figures 1, 2, and 3, the rings a
are connected by a spring c, the central part of. which is formed of a rigid semi-
circular bar k. In Figure 4 this rigid semi-circle k is shown attached to the
centre of the flat spring el. In both forms the rings a are also provided with
supports d, (Figures 2 and 3), which carry the arms e, the latter pivotted to and
turning upon the supports d, by means of rivets or screws f. The arms e are
prolonged in the form of studs, having bevelled ends at 7 fitting against corre-
sponding faces upon sockets which carry the slightly curved supports or pressure-
plates i, adjustable upon the nose of the wearer, the sockets and studs being
attached together by screws j, so that the former can have a slight play round
their axis, in one direction. It may be brought back and retained in the position
shewn, by an internal spring.
In the method of construction shown in Figures 1, 2, and 3, the lower ends of
the rigid semi-circle k are bent up into hooks which pass through and slide in
small rings upon the back of the arms e. When the rings a of the eye-glasses
constructed as described are opened or separated, they carry with them the two
supports d to which the arms e are pivotted,-the springs c, or c', being bent some-
what up by the opening, whilst at the same time the rings upon the pivotted
arms are kept constantly in the same position, by the hooked ends of the rigid
semi-circle k, which pass freely through them. The arms e are, therefore, together
with the pressure plates i carried by them, separated, turning upon the rings 7 as
centres, so that they take the position shown in dotted lines in Figure 3, and the
eye-glasses can then be adjusted upon the nose, where they are retained by releasing
the rings a and allowing them to return to their original or normal position in front
of the wearer's eyes. The pressure-plates are in this way moved into or out of
the required positions without touching or coming in the way of each other or of
other parts of the eye-glasses.
The other parts of the improved eye-glasses are similar to those ordinarily used,
and may be made of any suitable materials. The glasses or lenses may be
removed from the rings a by unscrewing the joint screws at m, and a ring or
attachment may be provided at n to receive a cord or chain. The pressure-
plates i may be made of any suitable material, preferably metal lined with cork.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved eye-glasses, having moveable pressure-plates to fit on the nose,
and consisting of two lens-rings a, connected elastically to a rigid curved bar k,
the ends of which are bent up and receive and retain at a constant distance apart
two rings at the inner end of the arms e which carry the pressure-plates, which
pressure-plates are also pivotted to supports d upon the rings a, in such manner
that when the two rings a are bent away from each other, the arms e are turned
round upon their axis formed by the rings which remain always in the same
position, so that the gradual separation of the pressure-plates is caused, substan-
tially as described and illustrated.
