Abstract: 408,649. Changing signs. RAPID AKT.-GES., Bruggen, Switzerland. Oct. 13, 1932, No. 28553. Convention date, Oct. 14, 1931. [Class 3 (i).] A display band wound on and off rollers 9, 10 is reversed at each end of traverse by reversing the current through a driving motor 14 by a switch 34. The motor is connected by bevel gearing 17, 18 and helical gearing 20, 22 to the roller 9 and by a chain 33 through helical gearing 29, 30 to the roller 10. The helical gears automatically throw clutches 24, 27 in and out of action to disconnect the winding-off roller from the motor. Brakes may be provided to retard the winding-off roller and keep the band taut. The switch 34 is automatically actuated at each end of traverse of the band by a buckle 50 which controls the switch lever 35. The buckle 50 is drawn up or down by cords 48, 49 attached to sectors 46, 47 which are given a part rotation by a rod thrust out through the end of each roller at the end of traverse. The rod is actuated by a spring-pressed bell-crank held down normally by a hinged flap forming part of the roller surface, but freed when the band is unwound. The band is built up of sections provided at their transverse edges with folded steel strips 57 notched at desired positions. In the notches engage flexible or hinged lamps 59, which allow of lateral and longitudinal relative motion of the sections. A similar joint connects the band to the rollers 9, 10. The notches may have a constricted entrance, or the clamps may grip the strips by spring pressure. Sections of varying width can be mounted in these strips, and lateral shutters may be provided on the casing to adjust the width of the viewing opening. The band 11 may be moved continuously, or intermittently by a contact control disc, and may be displayed on two sides of the casing. Several bands may be mounted in one casing, and be driven by one or several motors, and the bands may move in succession. Means may be provided for reversing the band at any position. The band may be illuminated by lamps at the front or rear. The band sections may be of woven fabrics, of non- inflammable cellulose, or of paper, devoid of wood-pulp, made transparent by oil, varnish, &c., and coated with material resistive to humidity and temperature change so as to retain its original size, and finally covered with talcum. The casing 1 has a door 2 to close the viewing aperture, and two side casings 5, 6 each provided with a door 7, 8.
