Improvements in and connected with Catching Apparatus for
Exposed Photographic Plates.
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 for improvements in and connected with catching apparatus
for exposed photographic plates has for its object to provide means for prevent-
ing the exposed plate falling into the developing space, or chamber, and the net
failing to act, and combines a disengaging apparatus directly with the movement
of the catching net.
According to this invention the plate lying behind the exposure chamber
rests on a slide normally held in position under the plate by a spring. The
slide is forced from under the plate against the action of the spring by a pusher,
near the end of which the net is suspended so that before the plate is allowed to
fall the net is brought directly underneath and catches the plate as it falls through
a slot.

Improvements in and connected with Catching Apparatus for
Exposed Photographic Plates.
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 for improvements in and connected with catching apparatus
for exposed plates, has for its object to provide means for preventing. the ex-
posed plate falling into the developing space, or chamber, and the net failing
to act, and combines a disengaging apparatus directly with the movement of
the catching net.
The accompanying drawing is a side elevation of apparatus constructed
according to this invention.
The plate P is supported in the camera behind the exposure chamber R on a
slide Snormally held in position under the plate by a spring F. The catching

page_text: apparatus HN is arranged in a developing chamber situated beneath the exposure
chamber. To allow the plate to drop, the slide is forced back against the action
of the spring F by a pusher H which carries the net N at its inner end so that
when the pusher reaches the end of its stroke the net is brought directly under-
neath and catches the plate as it falls through the slot L. The pusher H can be
drawn so far out of the developing chamber that the plate when it has fallen into
the net is put into the developing and fixing baths by the rotating and drawing
out of the pusher.
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
Catching apparatus for exposed photographs, the distinguishing feature of
which is that the pusher, which carries the catching net actuates a spring slide
and at the same time brings the net underneath a slot through which the plate
falls, so that the plate resting on the slide, must necessarily fall into the net.
