"
'IMPROVEMENTS IN BINOCULAR OR DOUBLE EYE GLASSES AND SPECTACLES."
COMPLETE SPECIFICATION filed by the said Joseph Porter Michaëls at the
Office of the Commissioners of Patents on the 25th June 1880.
JOSEPH PORTER MICHAELS, Surgeon Dentist, of 45, Avenue de l'Opera, in the
City of Paris, in the Republic of France. "IMPROVEMENTS IN BINOCULAR OR
DOUBLE EYE GLASSES AND SPECTACLES."
The subject of the present Invention is a new and important improvement in
binocular glasses, commonly known as double oye glasses or pinco nez, which said
improvement is equally applicable to all other kinds of eye glasses and spectacles.
The object of the Invention is to remedy many defects and inconveniences in
the method of construction at present in use, such, for example, as misplacement
on the nose, falling therefrom, and unsteadiness which is prejudicial to the sight.
It is more on account of these drawbacks to the use of eye glasses that doctors
and oculists recommend spectacles in preference on account of their greater
stability.
The modifications which I claim as forming a new and useful Invention consist
in adapting to the frames of eye glasses certain appliances, which from their
peculiar construction cause the glasses to abut against and extend from the arch
of the eye brow to the nose; thus by the employment of these auxiliary organs
forming regulators, the eye glasses are always easily and correctly placed in position
and at the exact and proper distance for the eye sight, whilst at the same time
they prevent accidental displacement.
Having thus described the nature and objects of my Invention I will now enter
more fully into the details of its construction, viz., my Invention consists in the
addition of two branches which I torm regulators; these are fixed to the frame of
the glasses at convenient parts thereof, or on the spring, so that when the glasses
are opened they project in such a manner and at such an angle with the plane of
the glasses that the extremities of the regulators can bestride the upper part of
the nose, and abut under and against the soft parts of the eye brow more or less
Dine 471

page_text: near the angle of the oye brow and the nose. The upward pressure of the glasses
produced by the action of the contracting spring causes the branches to seek a
place of rest under the eye brow arch, and hence perfect adhesion and stability
are obtained.
The accompanying Drawings represent the manner in which the branches
or regulators aro or may be adapted to eye glasses, and with slight modification to
spectacles.
The same letters of referenco indicate like parts in the several Figures; Fig. 1
represents a view of the eye glass provided with the movable regulators, having
their development outside the contracting spring; Fig. 2 is a side view of Fig. 1;
Fig. 3 is a representation of the same Figure showing the regulators open;
Figs. 4, 5, 6, show the regulators applied to the inside of the contracting spring and
represented in the same order as the three preceding Figures; Fig. 7 shows the
eye glass closed or shut; Fig. 8 represents the eye glass showing the regulators
open, and illustrating the position they occupy with reference to the glasses.
A is the frame of the glasses, either of metal or other substanco; B, B, are the
glasses; C, the contracting spring; D, the griffs which rest on the sido of the nose;
E, the regulators constructed on the principle already described as forming the
subject of my Invention.
The regulators are represented fixed to the frame by means of a little screw,
so arranged as to admit of sufficient play for their development when the glasses
are in use. When shut the regulators are placed in contact and behind the spring;
when opened their development is regulated by known means and at a proper
angle.
Having thus described the nature of my Invention and the mode of carrying out
the same, what I claim and desire to secure by Letters Patent is,-
1st. The appliances or auxiliary organs described and shown as applied to
binocular or double eye glasses (and with slight modifications to spectacles), the
said organs or branches being marked E, E, which may be fixed or movable, and
attached at certain points of the frame or spring, and placed or arranged in such
a manner that when used the extremities find rest and support under the parts of
the cyo brow arch, and being in opposition to the griffs D, D, greater security and
stability is obtained.
2nd. I claim such combinations, modifications, and additions as may be
necessitated for applying the principle to different systems of binocular glasses,
having as object (in arcbuting from and under the eye brow arch to and on the
bridge of the nose) the accurate and exact placement of the glasses for the eye
sight, with greater comfort and security in the habitual uso of the binocular
glasses.
In witness whereof, I, the said Joseph Porter Michaëls, have hereunto set my
hand and seal, this Twenty first day of June, in the year of our Lord One
thousand eight hundred and eighty.
