TRACING TABLES 
“ BARNES ” TRANSILLUMINATED 
A4760 
Originally developed for the Hydrographic department of the Admiralty for the detailed 
examination of charts printed on thick paper, the “ Barnes ” table is now produced for 
use in the drawing office for making tracings or for any work which requires a plan or 
drawing to be evenly illuminated from the reverse side. 
The illumination is provided by a fluorescent discharge tube fixed at the focal axis 
of a parabolic reflector. The light is therefore reflected in parallel rays so that the trans 
parent glass top of the table is evenly illuminated. 
The table is constructed of Prime Seasoned Beech and finished cellulose lacquer, 
self colour. A frosted glass screen 54 in. x 32 in. is fitted to the top and this is illuminated 
by means of a 40 Watt fluorescent strip lamp and parabolic reflector, which are located 
beneath the screen. The table is fitted with six feet of flex, and is designed to operate 
on mains voltage of 200 250 volts, 50 cycles. 
Overall dimensions:—3 ft. 6 in. x 3 ft. 5^ in. x 5 ft. I in.
