IMPROVEMENTS IN THE BRIDGES OF PINCE NEZ OR DOUBLE EYEGLASSES
Year: 1885

page_text: We WILLIAM CURRY and JOSEPH FIDOE PICKARD both of 195 Great Portland
Street in the County of Middlesex Ophthalmic Opticians do hereby declare the
nature of our invention for IMPROVEMENTS IN THE BRIDGES OF PINCE NEZ OR
DOUBLE EYEGLASSES to be as follows:-
Our invention consists of the combination of 2 or more pieces of metal or other
hard substance with a spring preferably a wire spiral spring so as to enable the
same pince nez eye glass to fit any size of nose this is usually accomplished now
by a flat metal spring which is very brittle and is constantly breaking rendering
the pince nez eyeglass useless and the spring has been mended. The terminals of
our new bridge are attached to the rim of the 2 glasses or the substance forming
the rim or frame of the glasses one glass at either terminal Two at least of the
pieces of metal or other hard substance of which the bridge may be made will at
the end farthest from their attachment to the glasses have a loop at a right angle
to the length of the piece of metal or other hard substance and through these loops
the other of the two pieces will be respectively passed and between the two loops
will be placed a spring which will have the effect of drawing the two glasses close
together. This spring may be a wire spring coiled round one of the pieces of metal
or other hard substance but it may be separate from the two pieces of metal or other
hard substance. The bridge may have two or more springs used in its construction
and two or more of the pieces of metal or other hard substance used in its con-
struction may have loops on them and travel respectively through loops on other
pieces of metal or other hard substance.

We WILLIAM CURRY and JOSEPH FIDOE PICKARD both of 195 Great Portland
Street in the County of Middlesex Ophthalmic Opticians, do hereby declare the
nature of our said invention of IMPROVEMENTS IN BRIDGES FOR PINCE NEZ OR
DOUBLE EYEGLASSES, and in what manner the same is to be constructed and
performed, to be particularly described and ascertained in and by the following
statement:-
The bridge is formed of two straight pieces of metal or other hard substance and
to one end of each is joined at a right angle a piece of metal or other hard
substance having a hole in it and which piece of metal protrudes beyond the
straight piece of metal on every side.
Figure I shows one of these straight pieces of metal or other hard substance
marked A and the piece of metal or other hard substance with a hole in it which
is marked B while the end of the straight piece of metal or other hard substance
furthest from B is marked C.
Round one of the two pieces is wound a wire spring between B and a point
short of C.
The ends C of the two pieces of metal or other hard substance are then
respectively passed through the loop or hole B in the other of them and attached
to the rim or frame of the glasses as shewn in figure II which shews the pince nez
or double eyeglasses fitted with our improved Bridge.
The effect of so constructing the Bridge is that the Glasses are drawn close
together by the expansion of the spring when not in use but when in use the
insertion of the nose causes the compression of the spring by the pressure of the
angled ends in which the hole B is pierced so that the glasses which fit the smallest
nose can be worn comfortably by a person having a large nose.
It is not necessary for the Bridge to be a flat one as instead of using one spring
two springs as described may be used one on either side.
This has always hitherto been attempted by the use of a flat spring which is
very liable to breakage.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be constructed and used we
declare that what we claim is :-
(a.) The method of constructing the Bridges of Pince Nez or double oye glasses
substantially as above described but we do not claim any of the parts of the bridge
separately.
