818,329. Lamps combined with notebooks. INVERESK ENVELOPE CO. Ltd. [formerly LEVY & CO. Ltd., A.], and MACKAY, W. R. July 2, 1957 [July 2, 1956], No. 20378/56. Class 39(2) [Also in Group XV] A notebook or like cover has combined therewith an electric torch which normally lies towards one end of the back hinge of the cover so as to be along the inner face thereof, but can be raised and switched on to illuminate the book, the torch having contacts which are closed automatically when the torch is raised and opened when it is lowered. The each comprises a casing 15, battery 16 and bulb 17 covered by a cap 18 either wholly or partly transparent or, as shown, with an opening 19 to direct light on to the book. The other end of the casing is closed by a plug 20 of insulating material through which a metal pin 21 slides, the pin 21 having an enlarged head 22 held against the battery 16 by a spring 23. The torch is pivotally mounted by a pin 24 between the side lugs 13 of a bracket 12 secured along the back hinge of a cover 10, the lugs 13 having two pairs of protuberances 26 to hold the torch in the down position and in the raised position shown in dot-dash lines. In the raised position, the pin 21 contacts a tongue 14 on the bracket 12 to complete the circut through the torch to the light bulb 17. The casing 15, bracket 12 and pin 21 are preferably of metal but may be formed of a non-conducting material with a conductive coating.
