Abstract

304,854. Terrett, H. C., and Scott, P. H. Nov. 2, 1927. Theatrical appliances.-A colour-changing illuminating device for scenic effects, &c. comprises a rotatable transparent disc divided into segments each having one of three primary colours and a rotatable opaque non-reflecting fan-shaped shutter, the disc and shutter being positively turned at different speeds. The disc 9 and shutter 12, 13 are mounted coaxially in front of lamps 3 and geared together by pinions 14, 18, 17, 10. The area of each of the shutter segments is at least equal to that of a colour segment of the disc. The sign legend may be on a facia 2 slidable in vertical guides, and may be optically-projected on to a screen.
