Abstract
841,888. Electric clocks. KIENZLE UHRENFABRIKEN A. G. March 25, 1957 [Nov. 27, 1956], No. 9680/57. Class 139 In an electric clock wherein the mainspring 1 is repeatedly wound-up by the armature 3 of an electromagnet 4 the centre of gravity S of the combined barrel 2 and mainspring 1 is offset from the barrel arbor O, e.g. by providing a peripheral recess 21 on the barrel, so that the turning moment on the barrel is substantially constant.
