Abstract

523,706. Ornamental effects. MOORE, H. A. March 20, 1939, No. 8849. [Class 93] [Also in Groups XVIII; VII and XIX] 'Edge-illuminated devices for displaying, signs, jewellery, ornamentation and indicators comprise sheets 20, having at the rear incised circular depressions or recesses 22 the bottoms of which approach more nearly to the front face 28 of the sheet the further they are from the light source 26. The sheet 20 may be transparent or translucent and may be coloured or fronted by a translucent coloured sheet. It may be enclosed on three sides by a metal frame and be backed by an opaque coating &c. which may be reflective. The recesses have frosted sides and may be cylindrical or conical in form either wholly or in part. The sheet may be wedgeshaped and the recesses of equal depth from the rear face, as shown in Fig. 5. Letters &c. may be formed as channels of varying depth, with recesses either located at the bottom thereof or arranged as a border. Two relatively rotating discs 68, 70, Fig. 14, may have each a series of recesses 22 which increase in depth the nearer they are to the axis of rotation 72. The light-admitting edge may be forked and be fitted with a colour filter, or may be bent at an angle to the main sheet, and the bent-over portion be itself furnished with recesses. A plurality of the devices may be disposed around a neon &c. elongated lamp, and in one form the device may comprise a shop-window pelmet. When applied to an indicator, recesses are formed both in the moving pointer and in the surrounding index face, and a single screened lamp arranged centrally of several indicators may be used as a common source of light.
