page_text: PROVISIONAL SPECIFICATION.
Improved Photographic Plate Holder and Charging Apparatus.
I, HERMANN OTTO FOERSTERLING, Engineer, of Friedenau, near Berlin, in
the Empire of Germany, do hereby declare the nature of this invention to be as
follows:
This invention relates to the production of a removable plate holder furnished
with plates, by means of which the apparatus is so charged that the charging
thereof with more than a single plate at one time is impossible.
According to this invention the plate holder which is in the form of a box
is filled with plates and fixed by means of its lid to a base or supporting piece.
The plate holder is capable of sliding in its lid and on side rails along a flap
fixed to the base the flap being thicker than the cover to the extent of one
plate between the slide rails so that when the plate holder is pushed forwards
only one plate can at any time remain lying on the flap. The flap is operated
by a lever to convey the plate that is to be exposed to the front of the exposure
opening.

Improved Photographic Plate Holder and Charging Apparatus.
I, HERMANN OTTO FOERSTERLING, Engineer, of Friedenau, near Berlin, in
the Empire of Germany, 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 charging apparatus or magazine for photographic
plates by means of which the photographic apparatus is so charged that the
charging thereof with more than a single plate at one time is impossible.
The accompanying drawing is a side view of the apparatus constructed accord-
ing to this invention.
The plate-holder P is filled with plates and fixed by means of its lid D to a
base or supporting piece B. The plate-holder is capable of sliding on its lid
on side rails along a flap S connected to the base. The flap S is thinner than
the cover to the extent of one plate between the slide rails, so that when the
plate-holder is pushed forwards only one plate can abut against the edge of
the cover, and remain lying on the flap S. The flap S is operated by a lever

page_text: engaging with a to convey the plate that is to be exposed to the front of the
exposure opening. The charging apparatus is firmly secured by its base to the
bottom of the exposure camera and remains there until the plates are used up.
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-
-
1. Photographic-plate holder and charging apparatus characterised by a remov-
able charging holder, which slides on its cover and also on the charging flap,
which is thinner than the cover to the extent of the thickness of one plate, so
that as the plate-holder is pushed over the flap only one plate at a time is
deposited thereon.
2. The improved photographic-plate holder and charging apparatus substan-
tially as described with reference to the drawing.
Dated this 26th day of June 1900.
