Abstract
955,499. Spring mechanisms. A. & M. FELL Ltd. Feb. 8, 1963 [Feb. 23, 1962], No. 7094/62. Heading F2S. [Also in Division G3] A clock (see Division G3) comprising a coiled driving spring (not shown) fastened at its ends respectively to a cylindrical drum 1 containing the spring and to a hollow arbor 4 on which the drum is rotatably mounted, and further comprising a clockwork mechanism located axially on one side of the drum and driven by the torque between the drum 1 and arbor 4 and having a clock face with hour and minute hands and a central seconds hand 17<SP>1</SP>, is provided with a shaft 20 driven along with the seconds hand, this shaft extending through the hollow arbor 4 to the other axial side of the drum 1 and being adapted thereat to provide a driving connection 22 to an external mechanism. The output to the drive 22, at one revolution per minute, may be represented by a torque of 20 gm. cm. which may be sustained for forty hours employing a spring of 30 kg. cm. torque.
