Improvements in and connected with Cameras.
We, ROBERT BALLANTINE and MATTHEW BALLANTINE, both of 101, Buchanan
Street, in the County of the City of Glasgow, North Britain, Opticians, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in cameras and has for its object to so
construct these that they are capable of being used either with films or plates at
the will of the operator.
In carrying out our invention we make the camera of any convenient shape and
on each side of it, towards the front, we make a recess, into one of which the film
is placed, while in the other the roller, in which the film is wound after
the exposure has been made, is carried. These recesses are provided with
suitable shutters. When the film is to be used for the purpose of taking the
exposures, it passes up through a slit or space between the outer and inner walls
of one side of the camera and over a roller and straight across the inside of the
camera behind the lens to the opposite side, and then passes over a similar roller
and down a corresponding slit or space, and after exposure it is wound on to the
spindle by means of a little knob or handle provided for the purpose.
In order to ascertain the number of the film being exposed at any stage we
provide an cychole on the back end of the camera covered over with mica or other
suitable transparent material and of any convenient colour so as to exclude the
light.
We also so construct the inside of the box that we can use films of two or more
different sizes.
When plates are to be used we simply detach the back of the camera and fix on
by means of catches or in any other suitable manner a box. Carried in this box there
is a smaller box, which slides in a groove and in which any convenient number of
plates are carried. This inner box is so constructed that, after an exposure has
been made, by slightly sliding or pulling it in an upward direction by means of a
little catch or handle connected to it, the plate falls out of the way, thus leaving the
next plate ready for exposure.
In order to retain the plates in their proper positions a spring is fixed to the
back end of this box and presses on the plates in a forward direction.

We, ROBERT BALLANTINE and MATTHEW BALLANTINE, both of 101, Buchanan Street,
in the County of the City of Glasgow, North Britain, Opticians, 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:-
Our invention relates to improvements in cameras and has for its object to so
construct these that they are capable of being used either with films or as a magazine
for plates at the will of the operator.
In order that our invention may be properly understood and readily carried into
effect we have hereunto appended one sheet of drawings of which,
Figure 1 is a longitudinal section, shewing the camera with box for taking with
plates attached also.
Figure 2 is part longitudinal section shewing the box in which plates are
held.
Figure 3 is detailed view of the spring arrangement for retaining the plates in
position.
In carrying out our invention we make the camera of any convenient shape and
on each side of it, towards the front, we make a recess A, A', into one, A. of which
the film B is placed, while in the other A', the roller C on which the film B is wound
after the exposure has been made, is carried. These recesses A, A¹, are provided
with suitable shutters D, D¹. When the film B is to be used for the purpose of
taking the exposures, it passes up through a slit or space E-between the outer and
inner walls of one side of the camera and over a roller G and straight across the
inside of the camera behind the lens to the opposite side, and then passes over a
similar roller G¹ and down a corresponding slit or space E¹, and after exposure it is
wound on to the spindle H by means of a little knob or handle I provided for the
purpose.
In order to ascertain the number of the film being exposed at any stage we
provide an eyehole J on the back end K of the camera covered over with mica or
other suitable transparent material and of any convenient colour so as to exclude
the light.
We also so construct the inside of the box that we can use films of two or more
different sizes.
When plates are to be used we simply detach the back of the camera and fix on
by means of catches or in any other suitable manner a box L. Carried in this
box there is a smaller box M, which slides in a groove and in which any convenient
number of plates N are carried. This inner box M is so constructed that, after an
exposure has been made, by slightly sliding or pulling it in an upward direction by
means of a little catch or handle O connected to it, the projecting piece or stop W
rises and so the plate N gets released and falls out of the way, thus leaving the next
plate ready for exposure, as seen in Figure 2.
In order to retain the plates in their proper positions a spring P, which is fixed
to a plate Q, and which is connected to the back end of this box by means
of catches or otherwise, presses on the plates in a forward direction.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
In cameras, constructing these so that they are capable of being used either with

page_text: films or as a magazine for plates at the will of the operator, substantially as
described, and illustrated in the accompanying sheet of drawings.
