606,178. Producing designs. BACHMANN, O. March 21, 1945, No. 7184. [Class 98 (i)] Designs are produced by a multiple pin-hole camera containing an apertured plate disposed between an illuminating device and photographic material, the plate being arranged in a rotatably and axially adjustable ring and having several sleeves, one end of each of which is nozzle-shaped, mounted in the apertures, the design to be reproduced being detachably mounted on a rotatable support. As shown, on one end of a drum 2, Fig. 1, is rotatably mounted a plate 7 to which can be clamped a design having a transparent image on a black ground in front of which a light source 11 is movable. Detachably mounted at the other end of drum 2 is a rotatable carrier 20 in which is mounted a member slidable in a direction at right angles to the axis of the carrier 20; this member has slidable therein in a direction orthogonal to the direction of movement thereof, a holder for photographic material. Near this end of the drum 2 an apertured plate 16, Fig. 5, is carried in gimbals, the outer gimbal ring 12 having pins projecting inwardly of the drum and passing through slots in the surface thereof so that it is rotatable and axially adjustable, and nozzle-ended sleeves 17 having small apertures 18 are inserted in the apertures of the plate 16. By axial movement of the ring 12 the multiple images may be caused to abut, to overlap or to be spaced.
