Abstract
1,020,456. Springs. E.T.A. A.G. EBAUCHES-FABRIK. Oct. 30, 1962 [Nov. 1, 1961], No. 41082/62. Heading F2S. [Also in Division G3] The rundown time of a clockwork spring barrel is increased, albeit with some slight loss of power and timekeeping ability in a later stage of the rundown, by a particular mainspring. This spring, Figs. 1-10 (not shown), comprises a spirally coiled blade, characterized in that an outer length 6 thereof adapted for connection to the barrel, is of the same thickness throughout, so as to deliver the correct driving force, whilst a second length 7 extending inwardly from the outer length and adapted for connection to the arbor, is of lesser thickness than the outer length 6. This enables the diameter of the arbor to be reduced and the space available for the spring to be increased. The thickness of the outer length may be
