Abstract
503,300. Illuminating pictures, signs, &c. HOARE; R. R. Oct. 2, 1937, Nos. 30661/38, 30662/38, and 30663/38. Divided out of 504,027. [Class 75 (iv)] [Also in Groups XV and XVIII] A picture, sign, or other surface G, which is mounted in a frame A and covered by a sheet of glass B spaced from the surface G, is illuminated by one or more lamps L disposed within a casing D which is secured in a slot K in the upper part of the frame A, the sides of the slot K and casing D being polished and a reflector R being provided so that a flat beam is projected over the surface G between the latter and the glass B. Slightly inclined strip mirrors are disposed along the base and two upright sides of the frame between the surface G and glass B so as to reflect light which would otherwise be lost back on to the surface G. The reflector R is hinged to provide access to the casing D, and passage of heat from the latter to the surface G is prevented by the provision of vents J and a glass plate F disposed across the lower end of the slot K.
