page_text: I, ISAAC GREENBURY, Jeweller 6 The Arcade Princes Street Edinburgh do
hereby declare the nature of this invention to be as follows:-
My invention consists in securing within a circular case a dial of transparent
material carrying views said dial being revolved by means of a knob secured to the
end of the case said knob having a connection with notched end for running on a
grooved wheel or box carrying said dial. I secure a small magnifying glass to the
front of said case for looking through and have a slit or holes at the back of the
case covered with glass for admitting light. By turning said knob the dial is
revolved displaying each view in rotation before the magnifying glass. Or in
place of revolving the dial by means of said knob arrangement
case in two halves and secure to revolve by means of a pivot running through their
may form said
centre the front half carrying said magnifying glass and the back half carrying said
dial with views. If found more convenient I may have the rim of said dial
projecting between said halves for revolving by means of the hand.
Dated this 10th day of September 1895.

I, ISAAC GREENBURY, of 6 The Arcade, Edinburgh, in the County of Mid-
lothian, North Britain, Jeweller 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 a pocket panorama and consists of a case which may be
made similar to a watch case and having within it a dial of transparent material
having around the edge of the dial a number of small photographic or other views.
A spy hole with magnifying glass is provided through the one case or side of the
instrument with a corresponding light hole through the opposite side, so that
by rotating the dial the photos may be brought one at a time opposite the spy
bole.
The said panorama may be used as a fancy article for the display of photo-
graphs or other pictures, in an attractive form and it may be at a cheap cost.
Figure 1 shows the case opened: Figure 2 the case closed: Figure 3 a section.
By rotating the knob a, the dial with the photographic views (illustrated by the
round dotted lines) is rotated through the gearing at 6 and the views brought
opposite the spy hole c, d being the light hole through the other side of the case.
If desired, I may employ a plate e to cover all the other views except the one
which is being looked at.
Or the photo dial may be rotated by the circular projecting disc portion f
Figure 4, which may have roughened edges for the purpose of rotating it round
with the finger and thumb. Figure 5 shews the case open and Figure 6 the case-

page_text: enclosed. A ratchet and pawl may be employed in this case to steady the rotation
as shewn in Figs. 4 and 5.
The said projecting disc f may be conveniently utilised by containing a compass
as shewn in Figure 7.
It is obvious that the precise mechanical details for bringing the photos opposite
the spy hole may be varied in many ways.
Also I may, if desired, dispense with the ratchet and pawl shewn in Figures 4
and 5, allowing the natural friction of the parts to keep the views steady.
The article may be attached to a watch or other chain for carrying the article in
the pocket.
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 :-
