Abstract

141,634. O'Neil, R. S. July 24, 1918. Lamp signals; transparency and stencil luminous signals.-An indicator particularly suitable for use in conjunction with the device described in Specification 141,388, [Class 40 (i), Electric signalling systems &c.], for indicating rudder positions comprises a single lamp 1 in a casing with a display aperture 7, and colour screens 2, 3 which can be selectively interposed between the lamp and aperture by linkwork under control of corresponding electro-magnets 4, 5. A number of translucent disks 6 bearing numbers or other indications are arranged round the aperture and selectively operated by electro-magnete to interpose any required disk between the coloured light and aperture, the general arrangement and operation being similar to that described in Specification 141,633.
