I, IVAN DE BALÁS, Landowner of Elemer (Toroutaler Comitat) Austria
Hungary, do hereby declare the nature of my said invention to be as follows :-
This invention relates to improvements in photographic apparatus for amateurs
and in the plate receptacles connected therewith which have for their object to
conveniently store a great number of plates and to fill in readily and promptly, a
large number of plates in order to take as many views in as short a time as
possible the exposed plates being collected in a suitable receptacle.formed in the
apparatus.
In the accompanying drawings
Figure 1 shows the receptacle for the plates and the camera in parallel
perspective.
Figure 2, shows likewise in parallel perspective the detached receptacle for the
plates already folded up.
Figure 3 is a vertical section on line rx of Figure 1 showing the apparatus or
camera being filled from the receptacle.
Figure 4 is a vertical section on line y y of Figure 1, and,
Figure 5 is a horizontal section on line zz of Figure 4.
Figure 6 is a side view of the photographic apparatus or camera.
Figure 7 is a vertical longitudinal section of the same.
Figure 8 is a horizontal section on line x-y of Figure 6, and;
Figure 9 is a detail.
Figure 10 is a vertical transverse section on line -z of Figure 6 and
Figure 11 is a similar section on line y z of Figure 6.
The improved camera (Figures 1, 3, 6 and 7) consists of a long rectangular box
or casing a the bottom of which forms a slide or drawer b which can be pulled out
in front. A second false bottom c placed above the first and likewise formed as-a
slide or drawer but which is pulled out at the rear encloses with the first bottom:b
a long and flat chamber d which is used for the storage of the plates already
exposed. Above the upper bottom e the box a is divided by a vertical transverse
partition into two similar chambers f and g the front of which forms the camera
proper which is arranged in the ordinary way. The construction of this camera,
and of its adjusting means have been left entirely out of the drawings for the sake
of simplicity. The rear chamber forms the receptacle for the unexposed plates.j
Figure 7 which are pressed against the bottom c by means of a spring hand. of the
pressure plate being held in a horizontal superposed position.. From the
chamber g the different plates; which have to be exposed are brought by the slide
or bottom. c into the chamber, f. For this purpose the part of the drawer.c
(Figures 7-11) which is below the latter chamber is reduced or thinned, out a
depth equal to the thickness of a plate so that the bottom of the rear chamber is
thicker than that of the chamber f. To bring a platej from the chamber g.into
the chamber the drawer c is half withdrawn from the apparatus so that the
lowermost platej of the chamber 9 falls into the reduced or thinned out part of the
drawer c.
When, the latter is slightly, pushed back again it carries by means of
the edge the plate j resting on its front side and introduces it into the chamber fƒ.

page_text: There are arranged in the side walls of the chamber fclose in front of the transverse
partition e two spring catches which are latterally depressed by the introduced
plate but are allowed to spring back as soon as the plate has passed behind the
same, so that by withdrawing again the drawer c (which is effected after having
taken a view) this plate is held by the same catches until the drawer has left
the space when it falls into the chamber d. The latter is divided by a small
plate m into a front and a rear part for the following purposes:-Should the front
part of d be already filled with exposed plates; the plate m is drawn back into an
opening or notch formed in the side wall by means of a pin n inserted through the
side wall of d, Figure 10 whereupon by tilting the whole apparatus the plates which
are in the front part of d are allowed to slide into the rear part of same where
they are firmly held by subsequently pushing the plate m back so that the front
compartment of d can now be filled anew. To ensure that the drawer or slide c
shall always be kept in the dark within the rear wall a vertical slide p is inserted
transversely throughout this wall above the slide c and is held by springs g, above
against the same slide c. To the above described apparatus belong the large plate
receptacle Figures 1 and 2. The latter is a double box built of two entirely
similar parts ss Figures 1 and 2 connected together by a hinger so that they can
be folded together as shown in Figure 2 for convenience of transport. Each part s
forms a separate box which has four vertical compartments t. Each compartment t
is closed at the top by a slide u and contains as many plates j as are required to
fill up once the chamber g of the apparatus a. The plate rests upon a wooden
base plate constantly pressed upwards in the way of the pressure plate x by
spring w. In the centre of the bottom of each compartment t is formed a small
opening y held constantly closed by a slide a' acted upou by a spring z.
opening y serves to introduce a pin 6' Figure 3 the screw threaded end of
which is screwed into a nut c¹ fixed to the plate v which is required to fill the
apparatus a.

This
In order to fill the camera a the latter must be first connected with the
receptacles as clearly shown in Figures 1 and 3. For this purpose each
compartment is provided above its closing slide with horizontal guiding grooves d'
while the camera a is provided at the lower edge of its rear half with corresponding
guiding ribs e¹. The camera a is inserted by its rear part so that the ribs e may fit
into the grooves d' of one of the compartments t the chamber g of the apparatus a
being now situated exactly above one of the compartments t. The slide u of the
compartment t being now opened the lowermost bottom or slide 6 of the camera a
is half opened and the slide c is entirely opened Figure 3 so that the compartment t
forms a single enclosure with the chamber g of the apparatus a. Now the pin b¹
above mentioned is inserted after having drawn back the slide a' through the
bottom of the compartment t and is screwed in the plate vso that the latter can be
raised by the aid of this pin 61 into the chamber 9 carrying the platej with it. In
the side walls of the chamber are two horizontal hooks Figures 3 and 11 which
must be previously withdrawn. These books are pushed in again when the plates
are already raised above them. The plate v has two latteral notches g¹ Figure 5
which enable them to be drawn back again into their compartment t without
remaining suspended to the hooks f. After the pin 61 is withdrawn all the slides
are closed again and the camera a is removed from the receptacles being now
ready for use. In the same manner the already exposed plates; of the camera
can be obviously transferred from the chamber d of the apparatus a to the
empty compartments of the receptacles so that with such a photographic
apparatus and assuming that each compartment t contained 20 plates; for instance,
160 exposed could be made which could not be done with the apparatus hitherto
'constructed.

1, IVAN DE BALÁS, Landowner, of Elemer (Torontaler Comitat) Austria
Hungary, do hereby declare the nature of my said invention, and in what manner
the same is to be performed to be particularly described and ascertained by the
following statement:-
This invention relates to improvements in photographic apparatus for amateurs
and in the plate receptacles. connected therewith which have for their object to
conveniently store a great number of plates and to fill in readily and promptly a
large number of plates in order to take as many views in as short a time as
possible, the exposed plates being collected in a suitable receptacle formed in the
apparatus.
The drawings referred to in this Complete Specification are those deposited with
the Provisional Specification.
Fig. 1 shows the receptacle for the plates and the camera in perspective.
Fig. 2 shows in perspective the detached receptacle for the plates folded up..
Fig. 3 is a vertical section on line x x of Fig. 1. showing the apparatus or
camera being filled from the receptacle.
Fig. 4. is a vertical section on line y y. of Fig. 1.
Fig. 5 is a horizontal section on line 2 2. of Fig. 4.
Fig. 6 is a side view of the photographic apparatus or camera.
Fig. 7 is a vertical longitudal section of the same.
Fig. 8 is a horizontal section on line x-y of Figure 6.
Fig. 9 is a detail.
Fig. 10 is a vertical transverse section on line x- of Figure 6.
Fig. 11. is a similar section on line y-z. of Figure 6.
The improved camera (Figs. 1, 36 & 7) consists of a long rectangular box or
casing a'the bottom of which forms a slide or drawer 6 which can be pulled out in
front. A second false bottom c, placed above the first and likewise formed as a
slide or drawer but which is pulled out at the rear, encloses with the first bottom b
a long and flat chamber d which is used for the storage plates already exposed.
Above the upper bottom c the box a is divided by a vertical transverse partition
into two similar chambers & g. the front one of which forms the camera proper
which is arranged in the ordinary way. The construction of this camera fand of
its adjusting means have been left entirely out of the drawings for the sake of
simplicity. The rear chamber g. forms a receptacle for the unexposed plates j.
Figure 7 which are pressed against the bottom c by means of a spring hand
pressure plate i. From the chamber ġ the different plates ; which have to be
exposed are brought by the slide or bottom c into the chamber f. For this
purpose the part of the drawer or slide c (Figs. 7-11) which is below the latter
chamber is reduced or thinned out a depth or equal to the thickness of a plate so
that the bottom of the rear chamber is thicker than that of the chamber f. To
bring a platej from the chamber g into the chamber f the drawer or slide c is half.
withdrawn from the apparatus so that the lowermost platej of the chamber g falls.
into the reduced or thiuned out part of the drawer c. When the latter is slightly
pushed back again it carries by means of the edge k. the platej resting on its front
side and introduces it into the chamber f. There are arranged in the side walls of
the chamber (close in front of the transverse partition e) two spring catches!
which are laterally depressed by the introduced plate ; but are allowed to spring
back as soon as the plate has passed behind the same, so that on again with-
drawing the slide (which is effected after having made an exposure) this plate j.
is held by the same catches / until the slide has left the space f when the plate

page_text: falls into the chamber d, the latter being divided by a small plate m into a front
and a rear part for the following purposes: Should the front part of d be already
filled with exposed plates; the plate m is drawn back into an opening or notch
formed in the side walls by means of a pin n inserted through the side wall of d, as
shown in Figure 10, whereupon by tilting the whole apparatus the plates; which
are in the front part of d are allowed to slide into the rear part of the same when
they are firmly held by subsequently pushing the plate m back so that the front
compartment of d can now be filled anew. To ensure a light tight connection
between the slide c and the box and when the slide c is removed therefrom a
vertical slide P. is inserted transversely throughout this wall above the slide c and
is held by springs 9 against the same slide c.
g
To the above described apparatus
belong the large plate receptacle Figures 1 and 2. The latter is a double box
built of two entirely similar parts ss connected together by hinges r so that they
can be folded together as shown in Figure 2 for convenience of transport. Each
parts forms a seperate box which has four vertical compartments t, each compart-
ment t being closed at the top by a slide u and contains as many plates; as are
required to fill the chamber g of the apparatus a. The plates rests upon a
wooden base plate v constantly pressed upwards by the pressure plate by a
spring w. In the centre of the bottom of each compartment t is formed a small
opening y closed by the slide a acted upon by a spring z. This opening y. serves
to introduce a pin 61 (Fig. 3) the screw threaded end of which is screwed into a
nut c¹ fixed to the plate v when filling the apparatus a.
In order to fill the camera a the latter must be first connected with the
receptacles as clearly shown in Figures 1 and 3. For this purpose each com-
partment t is provided above its closing slide with horizontal guiding grooves d¹
while the camera a is provided at the lower edge of its rear half with corresponding
guiding ribs el. The camera is inserted by its rear part so that the ribs e' may fit into
grooves d' of one of the compartments t, the chamber g of the apparatus a being
now situated exactly above one of the compartments t.
The slide u of the com-
partment being now opened the bottom or slide 6 of the camera a is half opened
and the slide c is entirely opened, (Figure 3) so that the compartment t forms a
single enclosure with the chamber of the apparatus a. The pin b above
mentioned is now inserted (after having drawn back the slide a¹) through the
bottom of the compartment t and is screwed in the plate r so that the latter can
be raised by the aid of this pin 6' into the chamber 9 carrying the plates with it.
In the side walls of the chamber are two horizontal hooks f¹ Figures 3 and 11
which must be previously withdrawn. These hooks are pushed in again when the
plates are already raised above them. The plate v has two latteral notches g¹
Figure 5 which enables it to be drawn back again into the compartment t. without
remaining suspended by the hooks/'. After the pin is withdrawn all the sides
are closed again and the camera a is removed from the receptacle's being now
ready for use. In the same manner the already exposed plates; of the camera can
be obviously transferred from the chamber d of the apparatus a to the empty
compartment of the receptacles to that with such a photographic apparatus and
assuming that each compartment t contained 20 plates j for instance 160 exposures
could be made which could not be done with the apparatus hitherto constructed.
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
1st. A photographic apparatus wherein a camera and a plate storing
receptacle g are arranged adjacently in a box or casing a the common bottom c of
both having the form of a slide used for inserting sensitized plates j from the
storage receptacle g into the chamber fon the one hand and for closing on the
other hand the space d below the two chambers 9 and f serving to receive
the plates already exposed the bottom B of this space d having likewise the form
of a s
slide.

page_text: 2nd. In the apparatus above claimed the bottom e having the form of a slide
half of which is situated below the chamber fand is reduced in thickness to the
extent of the thickness of a plate j so that by withdrawing the drawer e half its.
length the lowermost plate of those placed in the chamber g and held therein under
spring pressure falls onto the thinned or reduced portion of the slide c and is carried
away by the latter in order to be pushed back into the chamber f
3rd. The spring catches / in the side walls of the chamber f which give away to
the incoming plates while subsequently holding them behind as soon as the slide c is
withdrawn again in consequence whereof this withheld platej is bound to drop.
down in the space d.
4th. A plate storage receptacle forming an appendage of the apparatus or
camera claimed above consisting of two equal parts or boxes s capable of being.
folded together and connected by hinges reach part or box being divided into
four vertical compartments t closed at the top by a slide u and wherein the
sensitized plates rest on a wooden base plate v pressed upwards by a spring w in
the way of the pressure plate the plate; being thereby firmly held against the
closing slide u while each compartment t is provided at the bottom with an
opening y closed by an automatic slide a¹ and serving for the insertion of a pin b¹
screwed into the plate whenever the camera a is to be filled out of one of the
compartments.
5th. The arrangement whereby the apparatus a can be successively fixed with
the chamber g above each one of the compartments t so that by opening all the
slides the corresponding compartment t forms one space with the chamber g and
the plates can be raised in the way of the pin by means of which the plate v-
is eventually pushed upwards from the compartment t into the chamber where
they are pushed in by the hooks f¹movable in their side walls and are held thereby
until all the slides are closed again.
