Abstract

16,220. Bell, W. T. July 8. Signs; advertising.-Relates to electrically-illnminated signs &c, in which groups of incandescent lamps arranged to form words or other devices are successively illuminated and extinguished. Each lamp is independently connected with the main circuit through a switch, and the pushes P of the switches, are arranged beneath a jacquard cylinder A, over which passes the chain of pattern cards G, and which is reciprocated vertically by cam and spring mechanism d, d', the cylinder being rotated through a quarter of a revolution after each reciprocation by means of a lever system F<2>, F<3>, The depression of a push P is preferably caused to operate a toothed wheel through one tooth, and the toothed wheel in turn is caused to operate switch mechanism arranged to open and close the lamp circuit at each alternate tooth. In this case, two depressions of the jacquard cylinder are necessary for each word or device, one to switch the lamps ' on' and the other to switch them off.' To allow for this, pairs of corresponding pattern cards may be employed, or the card cylinder may be operated in such a manner as to bring a fresh card into position at each alternate movement.
