Improvements in Lorgnettes.
I, JEAN FEHL of Hanau, in the German Empire, Goldsmith, 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 :-
My invention relates to improvements in lorgnettes and the object of it is to
provide for the closing of the handles bringing the glasses into their functional
position, and for the releasing of the said handles, turning the glass down again.
Figure 1 is a front elevation shewing the handles closed and the glasses held in
their functional position.
Figure 1 is a front elevation shewing the handles apart and the glasses folded
down between the handles.
Figure 18 is a detail illustrating the action of the closing spring.
Figures 2 and 3 are detail views illustrating two modifications of the closing
spring illustrated in Figures 1 and 1B.
The lorgnette is composed of two handles or levers A, A1, the pivot a common
to them both, the frame A² with its glasses B, B, and the pivot b¹ upon or about
which the frame A² turns.
The pivot b is made fast to the outer end of one of the levers-according to
the construction illustrated, it is made fast to the lever A.
c is a spiral spring. It is made fast by its inner end to the pivot 6 and by its
outer end to the inner end of the frame A³ at a point, preferably, between the said
pivot and the adjacent glass B.
d is a pin fast to the inner end of the frame A' and from which it projects
at right angles therewith. The position of this pin on the said frame is of
importance. It is between the pivot and the adjacent glass B and below a line
drawu from the said pivot to the focus of the said glass-see Figures 1 and 1B.
e is a slot cut in the outer end of the lever A' in a proper position and wide
enough to receive the pin d and to allow of the motion, in either direction, of
the frame A and of the handles A, A'.
The free or normal condition of the spring c holds the frame A' between the
levers A, A' and the handles of the lorgnette apart, as shewn in Figure 1ª.
Pressure upon the handles A, A¹ separates the opposite ends of the levers, the
engagement of the slot e with the pin d swinging the frame A' about the pivot b¹,
through an angle of 90°, into the position illustrated in Figure 1. As, however,
the outer end of the spring c is fast to the frame A2, and the inner end to the
lever A (through the pivot b), the spring is put into a tension sufficient to
return both levers, handles, and frame to their, respectively, original positions, so
soon as the handles or either of them is released.
The modification illustrated in Figure 2 consists of a compressible spring c¹
lying in a recess c* formed to receive it in the handle A and lever A', partly
in the one and partly in the other. It may replace the spring c of the con-
struction illustrated in Figures 1, 14 and 1B. The ends of the spring c push
against both ends of the recess and as one of these is in the lever A' and
the other in the handle A-the direction of the action of the spring being to
one side of the pivot b',-the handles A, A' are pushed apart as soon as they
are released.
The modification illustrated in Figure 3 consists of a spring made fast to

page_text: one lever and acting against the other in the plyers joint of them both. This
modification is a substitute for the spring e of Figure 1 or that, c', of Figure 2.
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 a lorgnette, the combination of two levers pivotted together about half
way of their length; an eye-glass frame pivotted to the upper end of one of the
said levers; and a stud projecting laterally from the said eye-glass frame into
a slot in the said upper end to receive the said stud; substantially as set forth.
2. In a lorgnette, the combination of two levers pivotted together about half
way of their length; an eye-glass frame pivotted to the upper end of one of the
said levers; a spring secured with one end to the pivot of the eye-glass frame and
having the other end secured to the eye-glass frame itself, adapted to normally
depress the same between the said levers; and a stud projecting laterally from the
said eye-glass frame into a slot in the upper end of one of the said levers;
substantially as set forth.
3. In a lorgnette, the combination of two levers hinged together about half
way of their length; an eye-glass frame pivotted to the upper end of one of the
said levers; a spring near the pivot of the levels adapted to push the two handles
apart as soon as they are released, thereby turning the eye-glass frame down
between the levers; substantially as set forth.
