Description

SIGN
Filed April 6, 1929 Patented May 3, 1932 UNITED-STATES PATENT OFFICE WILLIAM ALBERT BURNS, OF BRONDESBURY, LONDON, ENGLAND, ASSIGNOR TO SOLA- FLEX SIGNS AMALGAMATED LIMITED, 01? LONDON, ENGLAND SIGN Application filed April 6, 1928, Serial No. 353,118, and in Great Britain April 17, 1928.
This invention relates to daylight signs and to prismatic glass for use therein.
The principal object of the invention is to provide a sign capable of being viewed effectively from lateral or slightly lateral positions. In the ordinary way, if a sign illuminated by daylight through a reflexive or refractive medium is hung at right angles to the face of a building (particularly near the street level of a high building) an observer only views such a sign effectively when he is at the same distance (or less) from the face of the building as the sign itself. As the distance a sign is allowed to overhang a pavement is relatively small only a proportion of passers-by on a wide pavement view it effectively.
Accordingly, a sign made according to the present invention and adapted to be hung out from the face of a building comprises a panel or stencil (hereinafter referred to as a stencil) and a ribbed prismatic refractive glass or a reflector whereof the ribs are inclined to the horizontal, the higher ends of the ribs being next the building. lVith this arrangement, the normal to the reflecting or refracting surface is directed laterally upwards and away from the building, and light derived from a lateral or vertical region of the sky is directed laterally of the sign after deviation to: render it visible to persons who are also laterally situated at the same side of the ll prefer to make the angle of tilt of the surfaces as large as possible to extend the field of view, the limit being usually fixed by the hei ht of buildings or other masks on the opposite side of a street. In an extreme case where the building carrying the sign is openly exposed, the inclination of the ribs may 7 approach the vertical.
Such signs having prismatic glass arranged to give what I may term lateral deviation, may be used in single-fronted signs, in parallel double-fronted signs, or in V-shaped double-fronted signs. In the case of double fronted signs care must be taken that neither construction masks the incident rays to the other. Considerable economy of space may be sometimes effected by arranging the prismatic glass with its ribs away from the stencil and towards the incident light.
' Several preferred forms are shown upon the accompanying drawings wherein Fig. l is a vertical sectional end view of a simple single-sided sign.
Fig. 2-is a similar view of an alternative form.
Fig. 3 represents a back view of the sheet ribs which have a long and a short face. The
Fig. 2 shows the frame 1,'stencil 2 and backing glass 3, but in this case the main lighting comes from behind, i. e. the right of the figure, and is transmitted through the glass; and the ribs may be regular and are acute-angled for satisfactory refraction and transmission of the light through the stencil. The ribs 30 are shown veryconsiderably inclined at Fig. 3, as for a position where the best light is derived from considerably to one side of the sign.
Figs. 4 and 5 show a double-sided form generally similar to the form shown at Fig. 1. The frame 1 holds a stencil 2 and backing gales 3 at each side. Daylight from the top and outer sides is reflected by the inclined silvered strips 3a, 3a shown shaded in Fig.
5. The casing also contains suitable sources of artificial light 4;, l at the top and side edges, subtended by the ribs, so as to illuminate the stencils in an alternative manner at night by throwing the light through the unsilvered steps or short faces 3?), 3b. In each case packing strips 5 are shown between the is arranged with the ribs running 2 prismatic side of the glass and the casing.
While I have described this invention in connection with outdoor signs, itcan be conveniently applied to indoor signs, or signs under cover provided awindow, fan'light,
