Improvements in Stereoscopes.
I, LOUIS JEFFERY, of 1 Newton Villas, Finsbury Park, in the County of
Middlesex, Dentist, do hereby declare the nature of this invention to be as
follows
By this invention I am enabled to exhibit in a stereoscope a continuously moving
panoramic view.
Two similar series of pictures each forming a continuous panorama are mounted
upon two endless bands to which a slow continuously revolving motion in the same
direction can be given.
Each endless band is made to pass around a drum by which it can be revolved and
also around two parallel guide rollers at a distance apart."
The two guide rollers of one band and the two guide rollers of the other are all in
one plane and parallel with one another.
A portion of each band stretched flat between two guide rollers can thus be
exhibited side by side with a similar portion of the other band just in the same way
as the two pictures are exhibited side by side on an ordinary stereoscopic slide and
can be viewed simultaneously by looking through the two lenses or eye pieces of the
instrument just in the same way as though an ordinary stereoscopic slide were being
used.
•
The two drums used for giving a revolving motion to the two endless bands may
be made to revolve simultaneously and at equal speeds by toothed wheels upon
them gearing with opposite sides of a toothed pinion driven in any convenient
manner.

I, LOUIS JEFFERY, of 1 Newton Villas, Finsbury Park in the County of
Middlesex, Dentist, 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:-
By this invention I am enabled to exhibit in a stereoscope a continuously moving
panoramic view.
Two similar series of pictures each forming a continuous panorama are mounted
upon two endless bands to which a slow continuously revolving motion in the same
direction can be given.
Each endless band is made to pass around a drum by which it can be revolved and
also around two parallel guide rollers at a distance apart.
The two guide rollers of one band and the two guide rollers of the other are all in
one plane and parallel with one another.
A portion of each band stretched flat between two guide rollers can thus be
exhibited side by side with a similar portion of the other band just in the same way

can be viewed simultaneously by looking through the two lenses or eye pieces of the

used.
•
The two drums used for giving a revolving motion to the two endless bands may
be made to revolve simultaneously and at equal speeds by toothed wheels upon
them gearing with opposite sides of a toothed pinion driven in any convenient
manner.
Figure 1 is a plan of a stereoscope constructed according to this invention the
cover b being removed.
Figures 2 and 3 are vertical sections on the lines 2-2 and 3-3 Figure 1
respectively.
a is the case b the cover ca hinged mirror throwing light into the interior and
d, the eyepieces.
e are the endless bands carrying the views they pass round the drums f and guide
rollers g the latter being mounted on plates / carried by spindles ; pressed outward
by the springs k so that the bands are kept in tension. The drums fare mounted on
toothed wheels gearing with the pinion m to which is fixed the bevel pinion n
gearing with the bevel pinion o on the shaft p which also carries a handle 9.
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. The combination with a stereoscope of means for continuously moving two similar
series of pictures each forming a continuous panorama substantially as described.
2. Stereoscopes substantially as described and shown in the drawings.
