TRUYDUNALDITION
A Combined Binocular and Photographic Camera or Stereoscope.
[, WILLIAM HENRY WOOD of 84 Foxberry Road, Brockley, in the County
of Surrey, Inventor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in binoculars and the like, and the object
of my invention is an opera, field or other binocular glass which is capable of also
being used as a photographic camera, stereoscopic camera or stereoscope.
In carrying out my invention I employ a pair of telescopic tubes such as are
used in' the construction of binoculars and the like, the inner one of each of said
telescopic tubes carries the eye lens and the outer one the object lens. Said inner
tubes are rigidly connected together and for the purpose of focussing, said outer
tubes are adapted to be simultaneously moved in a longitudinal direction' by
suitable means.
Each of the object lenses is removably fixed within' its outer tube and on said'
object lenses being removed I may fix in their places a pair of photographic lenses
which are provided with any suitable shutters.
At a suitable position within each of the inner tubes and at any desired distance
apart, I fix two diaphragms which are provided with suitable apertures, and the
peripheries of said inner tubes are also provided with apertures or slots which are
adapted to permit suitably constructed frames being inserted between said
diaphragms.
For the purpose of using my improved binocular as an ordinary hand or
detective camera, I remove both object lenses and fix two exactly similar
photographic lenses in position, I next insert the two frames between the
diaphragms, one of said frames carrying a dark slide and sensitised plate and the
other frame carrying a focussing screen of ground glass. I next remove the eye
lens of the tube in which the focussing screen has been inserted and fix in its stead'
convex focussing leus. On looking through the screen' carrying tube, the
focussing screen will show the picture that will be photographed on the sensitive
plate within the other tube and on account of the photographic lenses being both
exactly alike, the proper focus may be obtained-by the means described the
convex lens' serving to enlarge the picture on the screen thus enabling the focus to
be set very exact for obtaining a sharp picture. Any suitable dark slide and
shutter may be used.
For the purpose of using my improved binocular as a stereoscopic camera, I
obtain the focus as already described and then remove the focussing screen and
insert a second dark slide and sensitised plate, by which means a stéréoscopic
picture will be obtained. Or, I may fix a third tube to the binocular for the purpose of
focussing and may then insert both dark slides and sensitised plates simultaneously.
For the purpose of using my improved binocular as a stereoscope,' I remove
both the object and eye lenses and substitute lenses of suitable shape, and I insert
both of the frames which carry the necessary transparencies.

I, WILLIAM HENRY WOOD, of 84 Foxberry Road, Brockley, in the County
of Kent, Inventor, 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 binoculars and the like, and the object
of my invention is to make an opera, field or other binocular glass which shall be
capable of being also used as a photographic camera, stereoscopic camera or
stereoscope, in the manner substantially as hereinafter described.
In order that my invention may be readily understood, reference is made to the
accompanying drawings wherein like letters indicate corresponding parts throughout
the several figures and in which :-
Figure 1, represents a sectional view of a binocular glass constructed in
accordance with my invention, one tube carrying an object lens and the other tube
carrying a photographic lens.
Figure 2, represents one of the diaphragms P hereinafter referred to.
In carrying out my invention I enploy a pair of telescopic tubes such as are
used in the construction of binoculars and the like, the inner tubes A of said
telescopic tubes carrying the eye lenses B, and the outer tubes C normally carry
object lenses D. Said inner and outer tubes are respectively rigidly connected
together by means of ties or equivalents E, and for the purpose of focussing, said
outer tubes are adapted to be simultaneously moved in a longitudinal direction, in
the usual manner.
Each of the object lenses D is removably fixed within its outer tube C, and on
said object lenses being removed, I may fix in their places to the said tubes Ca
pair of photographic lenses F which are provided with any suitable shutters, said
shutters being preferably located in the space F¹.
At a suitable position within each of the inner tubes A, 1 fix two diaphragms P
which are formed with suitable apertures, preferably as shown in Figure 2, and the
peripheries of said inner tubes A are also provided with apertures or slots G which
are adapted to permit suitably constructed photographic dark slides being inserted
between said diaphragms.
For the purpose of using my improved binocular as an ordinary hand or
detective camera, 1 remove both object lenses D, and fix two exactly similar
photographic lenses F in their stead to the outer tubes C. I next insert a dark
slide containing a sensitised plate between the diaphragms P of one tube A and
between the diaphragms of the other tube A, I insert a slide carrying a focussing
screen of ground glass, mica or other suitable material. I next change the eye
lens of the tube A in which the focussing screen has been inserted and use in
its stead a suitable focussing lens H. On looking through the tube carrying
the focussing screen, a facsimile of the picture that will be photographed on the
sensitive plate within the other tube, will be seen, and on account of the
photographic lenses being both exactly alike, the proper focus may be obtained by
the means described, the focussing lens serving to enlarge the picture on the screen
thus enabling the focus to be set very exactly in order to obtain a sharp picture.
For the purpose of using my improved binocular as a stereoscopic camera,
I obtain the focus as above described, and then remove the focussing screen from
the tube A and in its place insert a second dark slide and sensitised plate, between
diaphragms P, so that, by means of the two lenses and dark slides, fixed side by
side, a stereoscopic picture will be obtained. I may employ any suitable means
whereby both shutters of the two lenses may be operated simultaneously.

page_text: Instead of first inserting a focussing screen within one of the tubes A and then
replacing said screen by a dark slide and sensitised plate, I may fix a third tube to
the binocular, which third tube is provided with a focussing screen so that I may
at once insert a dark slide and sensitised plate in each of the tubes A.
For the purpose of using my improved binocular as a stereoscope, I remove both
the object lenses and change the eye lenses for lenses of suitable focus, and I insert
a frame between the diaphragms of each tube A, which frames carry the necessary
transparencies. Instead of inserting said frames between the diaphragms as
described, I may use a suitably constructed frame which carries the transparencies
and which frame is fixed within the tube C in place of the ordinary object lenses.
My improved binocular may be used as a field or opera glass, detective camera
stereoscopic camera or stereoscope by merely changing the lenses and inserting the
necessary dark slide or transparencies as described, and a great advantage
appertaining to my improved binocular is that whether used for one or other of
the above purpose, the manner of holding or using said binocular is the same, the
end adapted to carry the eye lens being always put to the eyes of the person using
it, whereas in binoculars-adapted to be used as cameras-of the hitherto usual
construction, it has been necessary to reverse the said binocular when used for
photographic purposes clearly indicating the purpose of the person so using it.
I prefer to provide each of the tubes A. with a sliding lid A¹ by means of which
the apertures G may be closed, and I insert between each of the tubes A and C a
ring or equivalent of felt or other suitable material B', whereby the light is
completely shut out and the sliding of the outer tube over its inuer tube rendered
smooth and noiseless.
The lenses B and H may be secured to the tubes A in any suitable manner so
as to be readily changeable for the purpose hereinbefore described, but I prefer to
fix said lenses in suitably constructed quadrant frames J said frames being
supported at a suitable part of the tubes A by means of pins J', the arrangement
being such that on turning the heads J of said pins, the quadrant frames will be
swung therewith and consequently the lenses changed.
I wish is to be distinctly understood that I do not confine myself to any
particular construction of any of the parts contained in my improved binoculars,
as the construction of said parts may be varied without departing from my
invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
A binocular adapted to be used as a field or opera glass, detective camera,
stereoscopic camera or stereoscope, substantially as described and illustrated.
