page_text: I, DAVID YOUNG, Patent Agent, of the Firm of D. Young & Co., of 11 and 12,
Southampton Buildings, London, W.C., do hereby declare the nature of this inven-
tion to be as follows:
•
My invention relates in general to eye-glasses, and particularly to the con-
struction and arrangement of the bow-spring and nose-guards and the manner
of connecting them with the lenses or frame.
In my improved eye-glasses the spring and nose-guards are made of a single
piece. The spring is attached to the lenses or frames, as the case may be, from
the front and at right angles to the plane of the lenses. No coupling posts are
used. The offsets of the nose-guards are in line with the centres of the lenses.
No discomfort is experienced by the wearer from the pressure on the nose, and
the use of cork, rubber, celluloid, or other covering for the nose-guards is done
away with.
The objects of the invention are, first, to provide an improved, simple and
effectual support for eye-glasses; second, to do away with the pinching of the
nose by the nose-guards; third, to provide for accurately and permanently fixing
the optical centres of the lenses; fourth, to provide a support for the lenses of
eye-glasses, so constructed that, when it shall be once properly adjusted to the
eyes and nose of the wearer, it will not easily become disarranged.
Other minor objects of the invention will appear from the following descrip-
tion
The invention consists in the construction and combination of the parts as
hereinafter mentioned..
The eye-glasses hereinafter more particularly referred to are made without
frames; but it will readily be understood from the description that the invention
will apply as well to eye-glasses with frames.
In my improved glasses but seven separate pieces are used. The lenses form
two of the pieces. The third piece is made up of the bow-spring, the right nose-
guard consisting of the upper branch and the lower branch, the left nose-guard
consisting of the upper branch and the lower branch and two vertical projections.
The fourth and fifth pieces connect-the. lenses with the spring and nose-guards,
and two screws form the sixth and seventh pieces.
The bow-spring and nose-guards are stamped out of sheet-metal and belt to
form the arch or bow-spring and the two nose-guards. The upper branches of
the nose-guards are offset at certain points which, when the parts are all
assembled, are in line with the centres of the lenses. The upper branches of the
nose-guards project backwardly on a line. with the centres of the lenses, then

page_text: curve upwardly and forwardly, and incline toward the bow-spring, and the lower
branches extend downwardly in a vertical plane with the lenses.
The connections between the nose-guards and lenses are made as follows: Two
pieces are cut out of sheet-metal to form the combined ears, strap, and clip for
attaching the lenses to the nose-guards. After the blanks are stamped, they are bent
into the required form. The two extensions form ears which extend on each side of
the lens, and are provided with holes which register with a hole in the lens to
receive a rivet or screw. The points of the said extensions form the strap and
are bent to conform to the curvature of the edge of the lens. Suitable prongs are
adapted to be bent over to clamp one of two projections on upper branches of the
nose-guards and other prongs are adapted to be bent over to clamp one of the lower
branches of the nose-guards. The said clips thus firmly connect the nose-guards and
bow-spring with the lenses without the use of coupling posts and post-screws. The
only screws or rivets used in the construction are those which connect the lenses with
the ears of the clips. After the parts are assembled as described, the upper and
lower branches of the nose-guards and the bow-spring may be adjusted to the
nose of the wearer. The lower branches which are in contact with the bony
portion of the nose, do not pinch, their only purpose being to steady the eye-
glasses in their proper place. The eye-glasses are held firmly on the nose without
annoyance to the wearer by the upper branches of the nose-guards. Owing to
the peculiar shape and the positions of the upper branches of the nose-guards and
their co-operation with the bow-spring, the feeling to the wearer is that of security
and adhesion rather than pinching.
It will be observed that the bow-spring sits at approximately an angle of forty-
five degrees with the plane of the lenses, while the upper branches of the nose-
guards extend at a similar angle on the opposite side of the lenses. The effect
of this construction is to obtain a broad bearing-surface for the glasses on the
nose, it being understood that the bow-spring rests on the nose.
The forwardly
curving ends of the upper branches of the nose-guards also give a wide bearing
and tend to overcome the tendency to slip downwardly.
By the peculiar shape above mentioned, I refer to a torsional twist in the said
upper branches the effect of which is twofold. It makes the upper portion of
these branches conform to the shape of the portion of the nose upon which they
directly bear and also exerts a pressure, which adds to the effectiveness of the
device. The upper and lower branches also form the two ends of a spring, the
normal tendency of which is to exert pressure against the nose, though the lower
branches are so arranged that the pressure is very slight.

1, DAVID YOUNG, of 11, Southampton Buildings, London, W.C., Patent Agent,
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:-
My invention relates in general to eyeglasses, and particularly to the con-
struction and arrangement of the bow-spring and nose-guards and the manner
of connecting them with the lenses or frame.

page_text: In my improved eyeglasses the spring and nose-guards are made of a single
piece. The spring is attached to the lenses or frames, as the case may be, from
the front and at right angles to the plane of the lenses. No coupling-posts are
used. The offsets of the nose-guards are in line with the centers of the lenses.
No discomfort is experienced by the wearer from the pressure on the nose, and
the use of cork, rubber, celluloid, or other covering for the nose-guards is done
away with.
The objects of the invention are, first, to provide an improved, a simple, and an
effectual support for eyeglasses; second, to do away with the pinching of the
nose by the nose-guards; third, to provide for accurately and permanently fixing
the optical centers of the lens; fourth, to provide a support for the lenses of
eyeglasses so constructed that when it shall be once properly adjusted to the
eyes and nose of the wearer it will not easily become disarranged.
Other minor objects of the invention will appear from the following descrip-
tion.
The invention consists in the construction and combination of the parts herein-
after described, and pointed out definitely in the claims.
.
In the drawings, Figure 1 is a perspective view of a pair of eyeglasses embodying
my invention. Fig. 2 is a rear elevation thereof, and Fig. 3 is a plan
view. Fig. 4 is an illustration of the blank spring and nose-guards. Fig. 5 is a
side elevation of the spring and nose-guards detached. Fig. 6 is a vertical section
on line of Fig. 2. Fig. 7 is a blank of one of the combined straps and clips,
and Fig. 8 is a side view of the said strap and clip struck up into shape for use.
Fig. 9 is a rear perspective view, and Fig. 10 is an enlarged detail showing the
upper branch of one of the nose-guards.
Throughout the specification and drawings like parts are designated by like
characters.
The eyeglasses illustrated in the drawings forming part of this specification are
without frames; but it will readily be understood from the description that the
invention will apply as well to eyeglasses with frames.
In my improved glasses but seven separate pieces are used. The lenses 1
and 1º form two of the pieces. The third piece is made up of the bow-spring 2, the
right nose-guard consisting of the upper branch 2" and the lower branch 2", the
left nose-guard consisting of the upper branch 2b and the lower branch 21, and
the two vertical projections 2° and 24. The fourth and fifth pieces connect the
lenses with the spring and nose-guards, and the screws 6 and 6" form the sixth
and seventh pieces.
The bow-spring and nose-guards are stamped out of sheet metal in the form
shown in Fig. 4. The blank is then bent to form the arch or bow-spring 2 and
the two nose-guards. The upper branches 2" and 2b of the nose-guards are off-set
at the points 211 and 2011. When the parts are all assembled, these points 211
and 2 are in line with the centers of the lenses. The upper branches 2ª and 2b
of the nose-guards project backwardly on a line with the centers of the lenses,
then curve upwardly and forwardly, and incline toward the bow-spring, and the
lower branches 21 and 21 extend downwardly in a vertical plane with the lenses.
The connections between the nose-guards and lenses are made as follows: Two
pieces are cut out of sheet metal in the form shown in Fig. 7. These pieces form
the combined ears, strap, and clip. for attaching the lenses to the nose-guard.
After the blanks are stamped in the shape shown in Fig. 7 they are bent into
the form shown in Fig. 8. The two extensions 3 and 3 form ears which extend
on each side of the lens, and are provided with holes 3 and 3, which register
with a hole in the lens to receive a rivet or screw 6 or 6. The points 3d 3d
form the strap and are bent to conform to the curvature of the edge of the lens.
The prongs 3 and 3 are adapted to be bent over to clamp one of the pro-
jections 2 or 2d, and the prongs 3 and 31 are adapted to be bent over to clamp
one of the lower branches 21 or 21 of the nose-guards. Said clips thus firmly
connect the nose-guards and bow-spring with the lenses without the use of
coupling-posts and post-screws. The only screws or rivets used in the construction

page_text: are those which connect the lenses with the ears of the clips. After the parts
are assembled as described the upper and lower branches of the nose-guards and
the bow-spring may be adjusted to the nose of the wearer. The lower branches 21
and 2b, which are in contact with the bony portion of the nose, do not pinch,
their only purpose being to steady the eyeglasses in their proper place. The eye-
glasses are held firmly on the nose without annoyance to the wearer by the upper
branches and 2 of the nose-guards. Owing to the peculiar shape and the
positions of the upper branches of the nose-guards and their co-operation with the
bow-spring, the feeling to the wearer is that of security and adhesion rather than
pinching.
It will be observed that the bow-spring sits at approximately an angle of forty:
five degrees with the plane of the lenses, while the upper branches of the nose-
guards extend at a similar angle on the opposite side of the lenses. The effect
of this construction is to obtain a broad bearing-surface for the glasses on the
nose, it being understood that the bow-spring rests on the nose. The forwardly-
curving ends of the upper branches of the nose-guards also give a wide bearing
and tend to overcome the tendency to slip downwardly.
By peculiar shape" mentioned above I refer to the torsional twist in said
upper branches, as clearly shown in Figs. 9 and 10, the effect of which is
two-fold. It makes the upper portion of these branches conform to the shape of
the portion of the nose upon which they directly bear and also exerts a pressure,
which adds to the effectiveness of the device. It will also be observed that the
upper and lower branches form the two ends of a spring, the normal tendency of
which is pressure against the nose, though the lower branches are so arranged
that the pressure is very slight.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what claim is:
1. In eyeglasses, the combination of a bow-spring, nose-guards having lower
and upper branches, the latter being offset on a line with the center of the lenses
and curving backwardly and upwardly and having a torsional twist, and the
lower arms being in approximately the same vertical plane as the lenses, sub-
stantially as described.
2. In eyeglasses, the combination of a bow-spring and nose-guards, the bow-
spring entering from the front of the lenses and set at an angle thereto, and the
