A.D. 1867, May. -- No. 1526.
NEWTON, WILLIAM EDWARD.--(A COMMUNICATION FROM HENRY COOK.)--(PROVISIONAL PROTECTION ONLY.)--"IMPROVEMENTS IN PORTABLE PHOTOGRAPHIC APPARATUS."
1st. A cylindrical box, constructed to contain fifty or other convenient number of prepared and sensitised glass plates, which are brought, by means of tyhe simple rotation of the case, one after another, directly over a door, which opens and shuts automatically.
2nd. The photographic apparatus or camera. --This apparatus is like an ordinary opera glass. Its lenses are exactly similar in focus; one projects the image to be photographed on to the focussing glass, which occupies the large part of the tube; the other produces the image on the sensitised plate, which occupies a small dark chamber formed in the opposite tube. The above-mentioned cylindrical boxis pushed over an opening in the dark chamber; upon the doors of the box and of the chamber being opened simultaneously, a sensitised plate falls into the chamber. When the view has been taken, the apparatus is turned upside down, and the plate which has been exposed falls back into the box, which is then removed. The door of the box closes, and a small movement to the right or left brings another sensitised plate over the door and the opening in the camera.
A stand for the camera consists of a socket and upright post provided with a universal joint.
