PROVISIONAL SERUIFICATION.
An Improvement in Photographic Cameras.
I, EDWARD CHARLES HAWKINS Scientific Instrument Maker 12 St. Ann's
Terrace St. John's Wood London N.W. do hereby declare the nature of this
invention to be as follows:-
This invention is for the purpose of readily bringing a series of photographic
plates or films one after the other into position opposite a lens for exposure to the
action of light.
I provide for this purpose sheaths or carriers, to hold the said plates or films,
having arms or pins projecting from their lower corners, the said arms rest upon
guides or brackets affixed to the inner sides of the camera. The sheaths are pressed
forward by means of a spring, the top edge of the foremost sheath being retained by
a fixed stop at the top of the camera the projecting arms or pins engaging in
indented wheels, which upon being wholly or partially rotated, according to the
number of indentations, press the arms of the foremost sheath downwards, thereby
liberating the sheath from the aforementioned stop, and allow it to drop to the
bottom of the camera, the next sheath then advancing into position ready for
removal by repeating the operation.
The aforementioned wheels are rotated by other toothed wheels operated from the
outside of the camera by a suitable key or handle.
Dated this Fifth day of March 1894.
