Abstract

719,401. Signs. DALISON, A. W. M. March 13, 1953 [Jan. 7, 1952], No. 503/52. Class 3(2) [Also in Group XV] A device for illuminating signs comprises two compartments 6, 7 separated from each other by a heat resisting transparent partition 10 and communicating with each other only under the partition as at 14, or through holes in the bottom of the partition, air holes 20, 21 being provided only at or near the top of the compartments, a source of light 16 being placed in the compartment 6 and the sign being mounted in a frame 3 at the front of the compartment 7. The compartments are provided in a box-like structure 1 to which the frame 3 is attached by studs 4 which fit in holes in the box. The partition 10 may be held in a holder 11 by clip 12 and the air holes 20, 21 may be provided with light traps 22, 23. The sign is mounted in the frame 3 between a sheet of plain glass and a sheet of opal glass or between suitable plastic sheets. As the air in the compartment 6 is heated by the light 16 the hot air escapes through the holes 20 and cool air is drawn into the compartment through the opening 14 after being drawn into the compartment 7 through the holes 21 and over the back of the picture so as to have a cooling effect thereon.
