Abstract

1436006 Toothed gearing BUNKER RAMO CORP 2 Aug 1973 [29 Sept 1972] 36876/73 Heading F2Q [Also in Division G3] A worm drive mechanism for an electrically wound clock comprises a worm in the form of a helical wire spring 14 secured coaxially to a motor shaft 12 and having a portion of the spring extending as a cantilever beyond the end of the shaft 12, and a worm wheel 22 in engagement with the cantilevered portion of the spring. The pitch of the unstressed spring matches that of the worm gear.
