Abstract

787,469. Locking switches. GENERAL ELECTRIC CO., Ltd. Jan. 17, 1956 [Jan. 17, 1955], No. 1368/55. Class 38 (5). Two switch dollies 3, 4 are interlocked by a sliding plate 5 which is guided by pegs 10 and a slot 9 and which has an aperture 11 engaged by dolly 3 and a slot 12 engaged by dolly 4. Movement of dolly 3 to the " on " position from the " off " position shown is not possible unless dolly 4 is being moved to, or is already in, its " on " position, but dolly 4 can be moved " on " and " off " independently of dolly 3 when the latter is " off."
