Improvements in or connected with Eye Glasses and Spectacles.
I CHARLES JOHN BAILEY of 22 Boyeston Street, Boston, in the State of
Massachusetts one of the United States of America, Rubber Manufacturer 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 for its object the production of an improved nose piece for
eye glasses and spectacles.
Prior to my invention eye glasses have been provided with nose pieces which
acting as springs press on opposite sides of the nose to hold the glass in place, and
these springs have been faced with cork and other smooth material.
To enable the nose piece to act more effectually than heretofore, I have provided
them with a holding surface presenting a series of small feet to bear separately on
the side of the nose, the feet clinging to the skin better than a substantially smooth
or level surface, and preferably these feet will be hollow at their ends, so that when
applied to the skin, the air will be expelled, causing the hollow ends to cling to the
skin.
Fig. 1 shows a pair of eye glasses provided with my improvement;
Fig. 2, an enlarged face view of the holding surface detached from the spring.
Fig. 3, a section on the line a-x, Fig. 2,
Fig. 4 shows my invention applied to the bridge piece of spectacles, and
Figs. 5 and 6 show modifications to be described.
The eye glass frame a, and the spring nose piece b, attached thereto, are and
may be all as usual.
In accordance with my invention I provide a holding surface composed of a back-
piece c of india-rubber, cured in any suitable way and of any desired color,
it having projecting from it at one side a series of feet c', each preferably made
hollow, so as to present a chamber c 2.
The back e will preferably be made like a tube, and the feet c' will project from
one side of the tube, a portion of the toothless part of the tube embracing the nose
piece or guard of whatever shape, but if desired the back may be made of a single
thickness and be slitted near its end and be caught in said slits on the ends of the
nose piece e, as shown in Fig. 5, or the holding surface may be cemented to the nose
piece or guard or to a piece of rubber riveted to the nose piece, as in Fig. 6.
The feet will bear against the sides of the nose, one at a short distance from the
other, such construction enabling the feet to become separately seated in order
that they may hold better and more firmly to the skin, and being separated they
do not impede the circulation of the blood, as well as when the surface engaging
the skin is a smooth surface of a length equal to the acting part of the nose piece
or guard.
To yet further increase the holding action of the holding surface, the feet c¹ may
be and they are shown as made hollow or tubular, so that when applied to the skin
the air will be expelled, causing the feet to thereafter act by suction to increase
their holding power, the hollow feet being more delicate and sure in their action.
This invention is not limited to the exact shape or character of the nose piece,
as the nose piece may be of any usual shape or construction.
The nose piece of ordinary spectacles, being composed of metal, frequently exerts

page_text: a disagreeable pressure on the nose, and I may use my flexible holding surfaces at
the inner side of the nose pieces of spectacles, and in the foregoing description of
the construction and operation of the parts I have used the term eye-glass as
synonymous with spectacle.
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. An eye-glass or spectacles having a nose piece provided with a holding surface
presenting a series of flexible feet.
2. An eye glass or spectacles having a nose piece provided with a holding surface
presenting a series of hollow flexible feet.
3. An eye-glass or spectacles having a nose piece, composed of a tubular back
and a series of projecting feet.
4. An eye glass or spectacles having a nose piece, composed of a back, a portion
of which is made to surround. the nose piece leaving the feet attached to 'the back
to bear against. the nose.
5. The within described rubber holding surface for eye glasses or spectacles the
same presenting a series of cellular feet or projections.
6. The nose holding surface for eye glasses or spectacles herein shown and
described.
Dated the 6th day of March 1896.
