1Claim. (CI- 88-29)
This invention relates to improvements in through and having at the front ring ?anges
stereoscopes, and it is the principal object of my engaging the front face of‘ plate 20 to hold the
invention to provide ‘a stereoscope of simple and eye-pieces in place, while open or split rings 25,
inexpensive construction which can be folded 26 clamp the lenses 2|, 22 in place within their
into a comparatively small compass to be con
‘ veniently carried in a hand bag, pocket or the like.
Another object of my invention is the provision
of a foldable stereoscope the eye-pieces of which
are held in a novel and improved manner in the
O foldable front wall of the instrument.
A further object of my invention is the pro
vision of a stereoscope the rear and front walls
of which are held or supported in a wire frame
upon which they can be readily folded when
not in use.
A still further object of my invention is the
provision of a‘ foldable stereoscope the rear wall
of which is suited for the support of the ex
changeable pictures.
These and other objects and advantages of my
invention will become more fully known as the
description thereof proceeds and will then be
speci?cally de?ned in the appended claim.
In the accompanying drawing forming a ma
The material of the end edges of plate I! is
bent upon itself to provide guide‘ fianges?2l, 2B
for the picture cards 29 or the like made in the
usual two sectional form so that the rays com
ing from the picture strike the eyes as if com- 10
ing direct from an intermediate point, where'the
two pictures are seen apparently as one.
' In use plates 20, 15 are set up as illustrated in
Figure 1 while they may, when not in use, be
suitably folded upon the frame to be convenient- l5
ly carried on the person, or in hand bags or
folders etc.
It will be understood that I have disclosed the .
preferred form of my invention as one ex
ample only of the many possible ways to practi- 20
cally construct the same and that I may make
such‘ changes in the general arrangement and
in the construction of the minor details of my
invention as come within the scope of the ap
terial part of this disclosure:
pended claims without departure from the spirit 85
_ Fig. 1 is a perspective view of a stereoscope con
of my invention and the principles involved.‘
Having thus described my invention what I
claim as new and desire to secure by Letters
Patent is:
In a stereoscope, a wire frame open at one end 30
structed according to my invention.
Fig. 2 is a section on line 2-2 of Figure 1.
Fig. 3 is a top plan view of the stereoscope.
Fig. 4 is an end view thereof, folded.
As illustrated the stereoscope constructed ac- ’
cording to my invention consists of a wire frame
consisting of a pair of side bars III, II, the rear
- ends of which are connected by a bar l2, while
the front ends of bars l0, II are angularly bent,
as at l3 and I4.
A rear plate I5 is equipped with loops or eyes
I‘, ll through which the rear bar I2 is loosely
but frictionally guided so that the plate may be
conveniently folded upon the frame. ,
The angularly bent front ends I3, ll of bars
II, II are frictionally guided through loops or.
eyes ll, l9 formed in the material of the front
plate 20 so as to allow a folding of the plate
45 upon the frame.
The eye pieces or glasses 2|, 22 are held in
frames ‘or holders 22, 24 introduced through suit
able openings in the plate 20 extending there
and having its branches angularly bent at this
end, a picture holder plate having inwardly rolled
?anges to act as guides for picture cards, eyes
formed with the inner face of said plate through
which the rear bar of said frame is loosely but 86
frictionally guided, and an eye piece holder plate,
eyes formed at the inner face of said holder plate
for loosely but frictionally guiding the angularly
bent ends of said frame to hold the holder plate
in position but allowing a folding of the same ‘0
against said frame beneath the picture holder
plate when folded against said frame, and lenses
held in said eye piece holder plate by sockets
passed through said‘holder plate formed to en
gage the lenses from the rear and said plate from 45
the front, and a split ring engaging the front of
said lenses.
