Improvements in or connected with Pince-nez, Double Eyeglasses,
and other Spectacles.
1, JOHN JAMES WOOD, of 20, Lord Street, Liverpool, in the County of
Lancaster, Optician, do hereby declare the nature of my said invention to be as
follows:-
This invention has reference to pince-nez, double eyeglasses, or spectacles, and.
the chief object amongst others of my invention is to provide glasses which shall
be best for the eyesight, and at the same time shall be easy fitting and comfortable
to users.
There are practically two kinds of pince-nez, double eyeglasses, or spectacles,
namely, those which have a bridge so connecting the two glasses that the relative
positions of the foci of the two glasses are constant and provided with means of
different kinds for gripping the nose of the wearer, and those having a spring or
adjustable bridge wherein the relative position of the foci of the glasses is variable
and changes according to the shape and size of the user's nose, and which spring.
causes the pince-nez or spectacle to grip the nose, with or without additional or
secondary gripping devices. Of these the kind I employ, by preference, is that in
which the relative positions of the foci of the two glasses is constant or practically
constant when applied to the nose of the wearer; use this type because it is best
for the eyesight. In connection with the frame of the glasses, and to a suitable
part thereof, I fix a gripping device consisting of spring retained hinged or movable
gripping bearers, the hinge or movable support being susceptible of movement
laterally, and the gripping bearers being adapted to have oscillatory movement
about the point of their spring retained support. The supporting or retaining
spring or springs may be attached to the glass frames, or the bridge bar, and may
be of any suitable kind.
Although as above stated the form of glasses I prefer to use is that in which the
relative positions of the foci are constant when in use, nevertheless the
improvements connected with the gripping devices may be applied to other forms
of pince-nez or glasses or spectacles.

Improvements in or connected with Pince-nez or Double Eyeglasses.
and other Spectacles.
I, JOHN JAMES WOOD, of 20, Lord Street, Liverpool, in the County of
Lancaster, Optician, 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 following statement :-
This invention has reference to pince-uez or double eyeglasses, or spectueles, and
the chief object amongst others of my invention is to provide glasses which shall
be best for the eyesight, and at the same time shall be easy fitting and comfortable
to users.
There are practically two kinds of pince-nez or double eyeglasses, or-spectueles,
namely, those which have a bridge so connecting the two glasses that the relative
positions of the foci-i.e. centres of the two glasses are constant and provided with
means of different kinds for gripping the nose of the wearer, and those having a
spring or adjustable bridge wherein the relative positions of the foci-i.e. centres-
of the glasses are variable, and change according to the shape and size of the user's
nose, and which spring causes the pince-nez or spectacle to grip the nose, with or
without additional or secondary gripping devices. Of these the kind I employ
by preference is that in which the relative positions of the foei centres of the two
glasses is constant or practically constant when applied to the nose of the wearer
(I use this type because it is best for the eyesight), and in connection with
the frame of the glasses, and to a suitable part. thereof, I fix a gripping device
consisting of spring retained hinged or movable gripping bearers, the hinge or
movable support being susceptible of movement laterally, and the gripping bearers
being adapted to have oscillatory movement about the point of their spring retained
support. The supporting or retaining spring or springs may be attached to the
glass frames or the bridge bar, and may be of any suitable kind.
In the drawing I shew a pince-nez which serves to illustrates my invention. Ishew
as un-example a pince new of the kind in which the part connecting the two glasses
together is a fixed or constant one. In the drawing, Figure 1 is an elevation; and
Figure 2 is a plan.
With reference to the figures, a designates the gripping bearers, and bare the
spring supports. e is the frame for holding the glasses and d is the bridge piece
connecting the said frames together.
The gripping bearers a consist of cork, rubber, or other faced bars, or other bars
having an eye or hinge e at their back, such eye or hinge being supported from the
springs by a pin f' mounted or fixed in the support provided on the ends of the
springs b.
The spring supports, it will be seen, project inward of the glass-frame. In the
example shewn, this relation is effected by the projecting block or piece by which
The effect of this arrange-
the springs are supported by and from the frames c.
ment is that the path of the motion of the devices is out of the plane of the glasses,
and is consequently free; and moreover the gripping bearers hold the glasses a
convenient distance from the eyes.
In this example of pince-nez it will be seen the foei centres of the two glasses are
always constant, whatever the shape and size of the user's nose may be, and yet
may be used by persons having different sizes and shapes of noses, and applied to
different parts of a person's nose, and in any case the gripping bearers a will adapt
themselves to the shape of the wearer's nose and will be comfortable to him. This
is the form of frame I prefer to apply the above-described-bearers to, nevertheless
they may be applied to other forms of pince nez, or glusses or spectacles, with
advantage, as spring retained hinged gripping devices.

page_text: As regards the particular constructions and dispositions of the parts of the
devices herein set forth with reference to the example illustrated, these may be
modified and carried out in different ways under the invention, and springs of other
kinds substituted for the one shewn, and combined with the frame in modified
mauners.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements substantially as herein set forth in or connected with pince-
nez or double eyeglasses. and other spectacles.
2. A pince-nez or double eyeglasses, or other spectacles, wherein the relative
positions of the foci-i.e. centres of the glasses] are constant or fixed, and the
i.e. hinged-gripping bearers are adapted to be moved or adjusted laterally and
pressed onto the wearers nose by springs; substantially as set forth. also the
particular arrangement or construction of the hinged gripping bearers and springs
shown in and described with reference to the drawings.
