PROVISIONAL SPECIFICATION.
Improvements in or connected with Spectacles, Eye-glasses, and
Pince-nez.
I, JOHN MCPHAIL, of 3 Poplar Grove, The Elms, Dingle, in the County of
Lancaster, Master Mariner, do hereby declare the nature of my Invention to be as
follows:-
According to my Invention, there is provided an elastic bearing on that part of the
frame of the spectacles eye-glass or pince-nez that grip or rest on the nose of the
user. This elastic bearing is of such a nature that it will adapt itself to the contour
of the nose and will give a larger bearing surface than the ordinary frame or spring.
For the above purpose I employ a strip of India-rubber or a spiral coiled wire
or a combination of rubber flat or spiral spring so connected to each side of the
frame or spring piece of the glasses as to form an elastic hearing which will adapt
itself to the contour of the nose of the user.

COMPLETE SPECIFICATION.
Improvements in or connected with Spectacles, Eye-glasses, and
Pince-nez.
I, JOHN MCPHAIL, of 3, Poplar Grove, The Elms, Dingle, in the County of
Lancaster, Master Mariner, do hereby declare the nature of my said Invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
According to my Invention there is provided an elastic bearing on that part of the
frame of the spectacles, eye-glasses, or pince-nez, that grip, clip, or rest, on the nose
of the user. This elastic bearing is of such a nature that it will adapt itself to the
contour of the nose, and will give a larger bearing surface than the ordinary frame
or spring clip. For the above purpose I employ a spirally coiled wire, or a strip of
india rubber, or a combination of rubber and flat or spiral spring, arranged and
constructed as hereinafter fully described, and so connected to each side of the
frame or spring piece of the glasses, as to form an elastic bearing which will adapt
itself to the contour of the nose of the user when applied.
In the above description, and also in my Provisional Specification, I have stated
that the elastic bearing is made of india rubber, or coiled spiral spring, or combination
of rubber and flat or spiral spring, but in practice I find that the metallic coiled
wire is far superior and therefore preferable to rubber, and for that reason in this
specification I confine the description of my Invention almost entirely to eye-glasses
or pince-nez, and spectacles, etcetera, provided with the metallic coiled elastic
material as clips.
The accompanying Drawings which make part of this Specification, serve to
illustrate my Invention.
The Drawings are marked with letters of reference corresponding with those used
in the following explanation, and like letters are used to denote like or corresponding
parts throughout the several figures.
In the Drawings, Figure 1 is an elevation of a pair of eye-glasses or pince-nez,
with the improvements according to my invention applied thereto. This Figure
shows the normal state of the pince-nez before application to the nose of the user.

Figure 2 shows the state of the pince-nez when on the nose of the user. Figure 3
is an enlarged view of a portion of the eye-glass or pince-nez with my improve-
ments applied thereto. Figure 4 is an end-view of the spirally coiled wire which
forms the bearing and constitutes the clip for the nose. Figure 5 is an enlarged
view illustrating the construction of the spirally-coiled wire. Figure 6 is an end
view of the wire-coil. Figure 7 is an enlarged section of the wire. Figures 8 and 9
illustrate in a normal and extended state, respectively, the application of my Invention
to pince-nez having a straight expanding bridge, and hinged adjustable nose-bearings.
Figure 10 illustrates a strip of india rubber adapted to be used as the elastic bearing;
and Figure 11 is an end view thereof. Figure 12 shows the india rubber in the
form of a tube to be used in combination with a spiral coiled or other suitable spring,
to form the elastic bearing.
It will be seen that Figures 1, 2, 8, and 9 of the Drawings illustrate known forms
of eye-glasses or pince-nez with my improvements applied thereto.
According to my invention I make the bearings which constitute the clips of the
pince-nez of an elastic medium, a, (see Figures 1 and 2), so that when in position on
the nose, it will yield, as shown at a', Figure 2. To provide the spiral-wire coil with
a gripping-surface, it is drawn with the section shown at Figure 7,-namely, with a
hollowed-out face having projecting edges . These edges are milled, and thus a
rough surface is formed on the outside of the wire. The wire is then coiled on
a mandril into the form shown at Figures 5 and 6. To attach the spiral coil to the
frame, I provide the usual brackets c c, with short flat springs d d. These springs d d
enter and slip between the coils of the wire, as illustrated in Figures 3 and 4.
These springs d d keep the spiral coil in its place and prevent side motion. The
spiral wire may be attached to the springs d d by passing the ends of the wire
through holes e in the springs d d, as shown at Figure 4. The spiral coil is by
preference made of gold or silver wire, or metal, or alloy, that will not readily
tarnish.
The spiral coiled wire bearing clips a, above described, can be applied to any form
of folding, or rigid eye-glasses, spectacles, or pince-nez, which are held to the nose
by friction, and springs. For example, they can be applied to the form of eye-
glasses shown at Figures 8 and 9. In this case the bearing clips are hinged to the
frame of the glasses, and the coiled wire is attached to the clips, by the springs d d.
The norinal form of the coiled wire is shown at Figure 8, and Figure 9 shows the
form taken by the coiled wire when the eye-glasses are in use on the nose of the
wearer.
Now with respect to the use of india rubber elastic bearings, as the clips of a
pince-nez, provide pieces, such as a, shown in Figures 10, 11 and 12, and secure
them to the brackets & in any suitable way.
In Figures 10 and 11 the rubber bearing piece a is solid, and is secured to the
brackets e, by the spring pieces d, which ship into holes provided in the ends of the
rubber. The outside of the rubber pieces are provided with a roughened or milled
bearing surface such as that shown in Figure 10, or in any other suitable way, to
enable them to grip and hold onto the nose of the user to the desired extent.
Where the india rubber is used in combination with a spiral or equivalent metallic
spring, it may be applied in the form of a tube, as shown in Figure 12. In this
case the rubber is placed over the metallic spring, such spring being fastened to
the brackets c in any suitable way.
In the foregoing description of my Invention I have described its application
more particularly to that type of eye-glasses which are kept on the nose by the action
of a spring-bridge; but I would have it understood that my Invention is also
applicable to other types of eye-glasses, such as spectacles, in which the bridge or
connecting bar rests on the nose of the user. In this case the frame which contains
the glasses can be provided with the spiral coiled wire hearing a, as above described,
with reference to Figures 1 and 2; or, a secondary bridge consisting of a spiral
coiled wire, can be added under the main bridge or connecting bar of the spectacles.
*This secondary bridge is connected at each end of the frame of the glasses and forius

page_text: an elastic bearing pad, which rests on the nose of the user, and takes the weight of
the spectacles.
Although I have described a coiled wire as the best medium of which to make the
metallic elastic bearings, I would have it understood that they may be made of other
forms of metal springs, such as wave, zig-zag, and like springs, or wire, and provided
with roughened bearing surfaces.
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 :-
1. In spectacles, eye-glasses, and pince-nez, the combination with the frame, of an
elastic nose-bearing, consisting of a coiled wire, constructed substantially as described,
and which will adjust itself to the contour of the nose on which it bears or rests;
for the purposes set forth.
2. In spectacles, eye-glasses, and pince-nez, the combination with the frame
thereof, of an elastic nose-bearing, consisting of coiled wire, a, provided with milled
or roughened edges, said bearings being adapted to conform to the contour of the
nose of the user; substantially as described.
3. In spectacles, eye-glasses, and pince-nez, the combination with the frame
thereof, of an elastic nose-bearing, consisting of a coiled wire, or wave or equivalent
spring, having a milled or roughened surface; substantially as and for the purposes
set forth.
4. In spectacles, eye-glasses, and pince-nez, the combination with the frame
thereof, of an elastic nose-bearing, a, and retaining springs, d; for the purposes set
forth.
5. In spectacles, eye-glasses, and pince-nez, having hinged adjustable nose-bearings,
as described, the combination of spirally coiled wires a having milled edges b, and
retaining springs d; substantially as, and for the use and purposes, shown and
described.
6. The eye-glasses or pince-nez provided with the elastic bearings, a, constructed
and arranged as set forth, respectively, with reference to Figures 1, 2, and 3;
Figures 8 and 9; and Figures 10, 11, and 12, of the Drawings.
