Abstract

141,633. O'Neil, R. S, July 24, 1918. Lamp signals; transparency and stencil luminous signals.- An indicating device, 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, has a number of transparent disks 9 (not shown) mounted around a display opening 4 and adapted to be interposed selectively between the opening and a source of light by corresponding electro-magnets 5 and linkwork 6. The disks bear numbers or other signal indications. A number of lamps 1-3 of different colours are provided, and can be selectively illuminated. As described, a white light shows when the rudder is in midposition. When the rudder moves to either side a corresponding red or green light is shown, together with one or other of the numbered disks corresponding with the degree of movement.
