Improvements in or connected with Pince-nez or Double
Eye-glasses.
I, JOHN JAMES WOOD, of 20, Lord Street, Liverpool, in the County of
Lancaster, Optician, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has reference to pince-nez or double eye-glasses in which the
centres of the glasses are so fixed that once a wearer or user of such glasses has
obtained a pair with centres corresponding with the centres of his eyes, that is,
with the distance apart thereof, his eyes will always be coincident with the centres.
of the glasses and will always look through the centres of them, no matter what
part of the nose they are fixed upon. The chief objects amongst others of my
invention are to provide devices for gripping the nose, which shall effectually
support the eye-glasses or pince-nez thereon, that is support it firmly and at the
same time comfortably; and also, at the same time, to provide suitable elasticity
in the gripping bearers, combined with strength, so that they will withstand
considerable rough usage. A further object is to so construct or arrange the parts
of the glass or frame that they may be slid into and drawn out of a case, or the
pocket, easily, and without being so liable of catching in the pocket or case and
becoming strained or broken.
According to this invention, I combine with eye-glasses having a rigid or firm
bridge and fixed centres, arms mounted at one end upon a hinge or joint each
having a spring in connection with it, adapted to normally press the arms towards
the nose; and at the other end, gripping bearers which are hinged by a pivot or
equivalent loose joint through which said bearers may move or swivel about on
said arms; or, one only of said gripping bearers may be loose upon its joint and
free to swivel thereon, the other being fixed after fitted or adjusted to the wearer's
nose.
The said springs may be of coiled form, and enclosed within a case or box, or
sides, and hidden, or of other suitable form; whilst the arms are rigid or possess
little elasticity and great resistance against permanent bending.
To regulate the amount of movement of the holding on devices I may provide
stops on the frame near the gripper end of the arms which may have heads on or
so formed or constructed that the arms cannot be pulled away from the glasses or
frame... Or, stops may be provided on or in connection with the hinged joint
or hinges on which the arms are supported.
To render the glasses or pince-nez capable of being easily slipped into the pocket
or case, or drawn out therefrom, and without being so liable to catch and become
strained, I provide a duplex frame about where the holding devices come so that it
forms a guide or shield. Or, a guide bar or device may be provided outside or
about same producing the same effect.

Eye-glasses.
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-nez or double eye-glasses in which the
centres of the glasses are so fixed that once a wearer or user of such glasses has
obtained a pair with centres corresponding with the centres of his eyes, that is,
with the distance apart thereof, his eyes will be always coincident with the centres
of the glasses, and will always look through the centres of them, no matter what
part of the nose they are fixed upon. The chief objects of my invention are to
provide devices for gripping the nose, which shall effectually support the eye-
glasses or pince-nez thereon, that is support it firmaly, and at the same time
comfortably; and also, at the same time, to provide suitable elasticity in the
gripping bearer supports, combined with strength, so that they will withstand
considerable rough usage. A further object is to so construct or arrange the parts
of the glass or frame that they may be slid into and drawn out of a case, or the
pocket, easily, and without being so liable to catch in the pocket or case, and
become strained or broken.
'
According to this invention, I combine with eye-glasses having a rigid or firm
bridge and fixed centres, arm's mounted at one end upon a hinge or joint each
having a spring in connection with it, adapted to normally press the arms towards
the nose; and at the other end, gripping bearers which are hinged by a pivot or
equivalent loose joint or carrying support through which said bearers may move or
swivel about on said arms; or, one only of said gripping bearers may be loose upon
its joint and free to swivel thereon, the other being fixed, after being fitted or
adjusted to the wearer's nose.
The said springs may be of coiled form, and enclosed within a case or box, or
sides, and hidden, or of other suitable form; whilst the arms are rigid, or possess
little elasticity and great resistance against permanent bending.
To regulate the amount of movement of the holding on device I may provide
stops on the frame near the gripping bearer end of the arms, which may have heads
on or so formed or constructed that the arms cannot be pulled away from the
glasses or frame. Or, stops may be provided on or in connection with the hinged
joint or hinges on which the arms are supported.
To render the glasses or pince-nez capable of being easily slipped into the
pocket or case, or drawn out therefrom, and without being so liable to catch and
become strained, I provide a duplex frame about where the holding devices come
so that it forms a protecting shield. Or, a guard bar or device may be provided
outside or about same producing the same effect.
In the drawings illustrating this invention, Figure 1 is an elevation shewing a
pince-nez or double eyeglass having rigid or practically rigid hinged arms, and
hinged gripping bearers on the free ends thereof; and Figure 2 is an end view in
section, shewing the said arms and hinge, and gripping bearers, in detail.
Figure 3 is an elevation, and Figures 4 and 5 are, respectively, plan and end
view shewing forms of protecting shield or provision according to this invention.
The same letters and figures of reference are used to denote the same or like
parts wherever they occur in the different figures of the drawings.
Referring in the first instance to Figures 1 and 2, a are the glass frames, b is a
rigid or practically rigid bridge connecting said frames a together, and c are the
glasses. d are the rigid or practically rigid arms; and e are gripping bearers

page_text: hinged on the ends of the arms d. Each of the arms d'is hinged at its base to the
frames a, and is pressed outwards from their frames by springs, one of which, f, is
shewn on the right hand side of Figure 1, and in Figure 2. These springs fare of
cailed form as shewn, and are arranged in boxes h on the frames a, the outer end of
said springs being held to the side of the said boxes, say in a groove therein, and
the other in the cleft of central slit pins i, which are rivetted, screwed, or otherwise
suitably fixed in the cheeks d¹ forming the base of the arms d. The cheeks d'
enclose the sides of the boxes h and form sides thereto. The springs fare so
coiled and wound up in the boxes h that they tend to force the arms d outwards of
the frames, and onto the rose of the wearer of the glasses; and the limit of such
outward movement is controlled by the projecting stops on the boxes h, in
contact with which the parts of the base of the arms & come, when the glasses
are not being used, i.e. off the nose.
The gripping bearers, as stated, are hinged on the extremities of the arms d, the
hinges consisting of bosses d³, and bosses e on the backs of the gripping bearers e,
screw pins e² being used to connect these two bosses, the threaded ends of said pins
screwing into the bosses e'. In cases where it is desired to have one of the
gripping bearers e fixed, the screw pin e² thereof is screwed up tight after the said
gripping bearer has been set to the inclination of the wearer's nose, which
inclination is formed by fitting the glasses on the nose while it is loose.
By the above construction of the parts in combination with eye-glasses having a
rigid bridge and fixed centres, lateral adjustment of the gripping bearers, bodily, is
afforded by the hinged rigid arms d (which are pressed toward the nose by the
coiled springs f), while the gripping bearers e adjust themselves to the different
inclinations of different noses, and to the different parts thereof, by the hinges by
which said gripping bearers are supported on said rigid arms; and the pressure on
the gripping bearers, due to the springs f is distributed equally over the whole
surface of said gripping bearers, by said hinges being disposed centrally or nearly
centrally in the length thereof..
It is to be stated that no claim under this invention is made to the springs f,
boxes h, and the mode of connection or to the eye-glasses with a rigid bridge,
per se.
Referring now to Figures 3, 4, and 5, there is illustrated in these figures the
means according to this invention by which the arms d, when consisting of spring
metal (constituting springs) are shielded or protected against being injured-
i.e. bent out of position or broken-by rough usage, as when caught in the pocket
or case, in being pulled out or pushed in; or, under like circumstances. The
construction shewn on the right hand side of Figure 3, and in Figure 4, consists of
a duplex frame; namely, in addition to the frame a there is provided a second
frame bar a' on the inner side of the spring arms d, said frame bar a¹ being
connected at its lower end to the block to which the spring arm d is fixed, and at
the top to the bridge b. A bar a² is provided midway between the frame bars a
and a-to which it is fixed-to limit the outward movement of the springs d, and
to serve as a stop thereto, the arms d passing between the frame bars a and a¹
above said bar a³, as shewn.
On the left side of Figure 4, and in Figure 5 the shielding or protecting means
consists of a bar a¹ on the frame a and carried round or about the upper end of the
spring arm d, the lower bar a² serving as a stop to limit the outward movement of
said arm.
This construction of spring arms d and hinged gripping bearers e above described
is set forth in the Specifications of my former Letters Patent No. 4280 of 189
and No. 7888 of 1891, and is therefore not claimed per se under this invention.
As a modification of the construction set forth with reference to Figures 1 and 2,
in lieu of the coiled springs f, plain springs f, shewn in dotted lines, may be
employed to press the arms d outwards from the frames a; in which case the
arms may be mounted on the frames a-or glasses as the case may be-by simple
hinges.

page_text: In some cases the shield or protecting bars a! (or a' and a²) may be employed in
connection with the pince-nez set forth with reference to Figures 1 and 2, for
providing against straining of the parts.
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 herein described improvement in or connected with pince-nez or double
eye-glasses, consisting of the combination with piuce-nez or double eye-glasses the
centres of the glasses of which are fixed, of rigid arms a hinged on the frames or
glasses thereof, gripping bearers (or one gripping bearer) e having oscillatory
movement upon game, and springs by which said arms are pressed outwards and the
gripping bearers onto the nose of the wearer; operating substantially as and for
the purposes set forth.
2. The double eye-glasses or pince-nez having its parts constructed, combined,
and adapted to operate particularly as set forth with reference to and shewn in
Figures 1 and 2 of the drawings, for the purposes specified.
3. The herein described improvement in or connected with pince-nez or double
eye-glasses, consisting of the combination with pince-nez or double eye-glasses the
centres of the glasses of which are fixed, of spring arms & fixed on said frames or
glasses thereof, gripping bearers (or one gripping bearer) e having oscillatory
movement upon same, and shield or protecting bars a' (or a and a²); substantially
as set forth with reference to and shewn in Figures 3, 4 and 5 of the drawings.
