- Description:
- This apparatus is to enable photographic dry plates or films, when placed in the envelopes provided, to be changed in daylight. The envelope is of a stiff, light-proof cloth, in two parts, and is laid within the slide upon the shutter. The shutter has a groove which engages with a prominence upon the flap of the envelope, so that when the shutter is drawn the flap of the envelope is drawn from over the plate with it. There is an opening in the back of the slide, covered with celluloid, through which may be seen whether the envelope flap is working properly, and any number upon the envelope. After exposure the shutter is closed, the same action closing the flap of the envelope, which, with the plate inside, may then be removed and another inserted in its place. Only one slide is required, and this may, if desired, be built into the camera and form an integral part of same.
