Abstract
336,786. Henkes, C. C. Oct. 14, 1929. Monogrammic signs.-In monogrammic signs wherein the making and breaking of the circuits of a field of electric lamps is controlled by a movable perforated strip D passing between movable contacts C with hemispherical heads and a contact plate B, the plate B is magnetized by permanent or electro magnets A<1>, A to attract the contacts C and to reduce the arc at the points of contact by the blow-out effect of the magnetic field. Springs L or mercury J may be used below the contacts 0 to secure positive contact with the guides H, which are connected to the lamps.
