Abstract
502,424. Monogrammic signs. SOC. D'APPAREILS LUMINEUX ANNONCIATEURS & SIGNALISATEURS, and BOSCHE, A. E. J. Sept. 23, 1937, No. 25847. [Class 118 (ii)] In signalling, advertising, and like devices in which a plurality of relatively movable perforated plates are arranged in pack form and co-operate with a stationary plate or plates and a luminous source to give selected indications which depend upon the relative positions of the plates, the plates are lifted by individual electromagnets operated from remote control. The core 11 of each electromagnet 10 has a projection 12 which engages an eye 13 in the top of each plate 7, a spring 16 bearing on the projection 12 to force the plate down on to a ledge 15 when current is out off. Two bails 24 on shafts 23 normally press on the pack of plates, to keep them in position, under the influence of springs 25. Cores 18, 19 are retracted by a solenoid 17 to turn the shafts 23 and release the pack prior to movement of one or more plates 7, the solenoid being in series with the electromagnets 10. A plurality of the devices may be arranged side-by-side, each being connected to a relay which leads the current to the required devices in succession. Specification 370,728, [Group XVIII], is referred to.
