COMPLETE SPECIFICATION.
Improvements in Pince-Nez or Double Eye-Glasses.
1, SIGMUND LUDWIG GOLDMAN, of 3° Bradford Avenue, Redcross Street, in the
county of London, Merchant, 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 relates to improvements in pince-nez or double eye-glasses of
the kind wherein a rigid bridge is employed and wherein the placquets are pivoted
at their centre and are connected to the frame of the eye-glasses by spring con-
nections: the object of the invention being to so construct pince-nez or double
eye-glasses that the placquets whilst possessing the necessary amount of elasticity
in the plane of the eye-glasses shall yet be perfectly rigid in a plane at right angles
thereto.
According to my invention I pivot each placquet at its centre to one end of a
rigid arm or bar the other end of which is pivoted to the bridge of the frame. To
give the necessary inward pressure to the placquets to enable them to fix the
glasses in position upon the nose of the wearer I provide springs one end of
each of which is rigidly connected to the frame of the eye-glasses whilst the other
end is loosely connected to the placquet or to the arm or bar holding the placquet
in position.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is an elevation to an exaggerated scale of pince-nez or double eye-glasses
having my improvements applied thereto :
Figure 2 is a section on the line 2-2 Figure 1.
a is the frame of the pince-nez or double eye-glasses and 6 the rigid bridge
thereof. , are the placquets and d, d' are the arms or bars to one end of which
the placquets are pivoted at about the middle point of their length, the other ends
of the said bars d, d being pivotally connected to the bridge h. The bars d, d
are formed with short extensions or stops d¹, d¹ to limit the extent to which the
placquets can move.
,e are the springs which are preferably made of twisted wire the said springs
being rigidly secured to the frame of the pince-nez or eye-glasses at f, f and being
formed at their free ends with hooks g, g engaging eyes h, h on the bars d, d.
With this construction of pince-nez or double eye-glasses it will be obvious
hot the placquets whilst possessing the requisite amount of elasticity in the
plane of the glasses to enable them to adapt themselves to and grip the nose of
the wearer yet they are held rigidly in the said plane by the bars d, d.
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 pince-nez or double eye-glasses of the kind wherein a rigid bridge is
emploved pivoting the placquets to bars hinged or pivoted to the bridge and

page_text: applying the necessary inward pressure to the said placquets by means of springs
(preferably made of twisted wire) connected to the frame, substantially as described
and illustrated.
2. The manufacture and use of the improved pince-nez or double eye-glasses
herein before described and illustrated in the accompanying drawing.
