page_text: I, JACOB PILLISCHER, Manufacturing Optician and Scientific Instrument Maker,
of 88, New Bond Street, in the County of London, do hereby declare the nature
of this invention to be follows:-
This invention has for its object improvements in eye glasses. Hitherto eye
glasses have usually been made with a solid frame having sides
extending over the ears, or in the form of folders.
or "wings"
A third form has of late years
been constructed without the side pieces, having springs and plates or plaquets
to retain it on the nose.
Now this form although convenient in some respects, yet, as hitherto made, has
several defects, it is heavy, unsightly and complicated.
My present invention has for its object to obviate these defects and accordingly
I construct the eye glasses as follows:

The frames are of any suitable shape so as to receive any desired form of lens.
Instead of connecting the frames by an arch-bridge
bars, in conjunction with springs, as has been done, I unite the same by means of
or by a parallel bár or
a crank or
sweeping W" bridge. This enables me exactly to adjust the
relative positions of the lenses, and the shape of the bridge to the requirements of
the wearer.

Above the bridge, at either side, a light spring is attached and passes along the
frame down to a convenient point below the centre-line. The springs are then
bent upwards and inwards and fitted with plaquets to bear against the nose of the
wearer in the usual manner.
It will thus be seen that instead of mounting the plaquet on a special support
and actuating it by a spring, the spring, being bent to shape, forms a single piece
with the plaquet, following the outline of the frame on the one side and that of the
nose on the other.

glasses have usually been made with a solid frame having "sides wings"
extending over the ears, or in the form of folders. A third form has of late years
been constructed without the side pieces, having springs or plates, or plaquets,
to retain it on the nose.
Now this form although convenient in some respects, yet, as hitherto made, has
several defects. It is heavy, unsightly, and complicated.
My present invention has for its object to obviate these defects and accordingly
I construct the eye-glasses as shown in the accompanying drawings, in which:
The frames A. A. are of any suitable shape so as to receive any desired form of
lens. Instead of connecting the frames by an arch-bridge, or by a parallel bar or
bars, in conjunction with springs as has been done, I unite the same by means of
crank" or "sweeping W' bridge at B. This enables me exactly to adjust the
relative positions of the lenses, and the shape of the bridge to the requirements of
the wearer.

Above the bridge, at either side, light springs C, C, are attached and pass along
the frames A, A, down to a convenient point below the centre line. The
springs C, C, are then bent upwards and inwards and fitted with plaquets D, D, to
bear against the nose of the wearer in the usual manner.
It will thus be seen that instead of mounting the placquet on a special support
and actuating it by a spring, the spring, being bent to shape, forms a single piece
with the plaquet, following the outline of the frame on the one side and that
of the nose on the other.
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:-

In eye-glasses the combination of the frames with a crank-bridge" or a
"sweening W" bridge, springs C, C, and plaquets D, D, all as set forth and
illustrated in the drawings.
