Abstract

521,216. Actuating window blinds and screens or shutters for advertising devices and signals. LUCAS, Ltd., J., and PURDEN, R. H. Nov. 12, 1933, No. 32939. [Class 20 (iii)] [Also in Group XVIII] Blinds for vehicle or other windows, screens or shutters for advertising purposes or signals, are operated by means comprising a reversible electric motor, and a one-way clutch through which the blind &c. is actuated in one directon against the pull of a spring or weight adapted to move the blind &c. in the opposite direction when the motor is appropriately set. As shown in Fig. 1, the free end of the blind a is connected by cords n to a helical spring k fixed at m. The roller b is geared by belts e, h to the electric motor g which is reversible to permit closing of the blind by the spring, or opening by means of the motor against the pull of the spring. In the modification shown in Fig. 2, a coil spring k is fitted to the roller, the chords n being connected to the motor-driven shaft f. The pulley i on this shaft is fitted with a oneway ratchet-clutch. The device may be applied to sliding-blinds or other screens carried by guides.
