Abstract
193,039. Soc. Baille-Lemaire et Fils. Feb. 10, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Cameras for plates and roll-films are so constructed that the plates are exposed in the same focal plane as the film, thereby avoiding the necessity of a focussing adjustment. The guide roller. 3, Fig. 1, for the film is mounted on a frame 1 which is pivoted at 2. An abutment 7 on the removable back 8 presses the frame 1 and roller 3 into operative position for roll films, and when the back 8 is removed, the frame 1 and roller 3 are rocked by a spring 6 into idle position, as shown in Fig. 2, thereby allowing the insertion of a plate-holder in the same focal plane as the roll-film occupied.
