Abstract

327,406. Hoppe, G. Dec. 18, 1928, [Convention date]. Optical - projection apparatus. - Appara.- tus for displaying advertising pictures in shop windows, exhibition halls, &c. consists of a projector casing k, Fig. 1, a reflector casing m, bellows c connecting the two casings in one unitary structure, and rods e carried by the projector casing and working in fixed nuts n for focusing the apparatus. The apparatus described, which is shown in Fig. 1, is duplex in form so that the pictures may be visible at the same time to the public in a street and in the shop. The projector a is enclosed in the casing k and projects pictures from an automatically-moving band l either in rapid succession or intermittently. The bellows c connects the casing k in a light-tight manner with a box m containing a translucent screen d, a mirror b, and a transparent plate g. The mirror b is pivoted on a shaft h and adjusted by an arm f outside the casing. The plate g is hinged to the mirror b and to plate i which is pivotally and slidably movable in a slot t. The rods e are rotated by bevel gears for focussing the apparatus. Above or below the plates g are mounted mirrors b<2> by which transparent signs d<1> illuminated by natural or artificial light are projected.
