Abstract

492,335. Clockwork mechanism. AEBERHARDT, H. March 15, 1937, No. 7531. Convention date, March 21, 1936. [Class 139] [Also in Group XIX] In a combined watch and dateindicator, a spring barrel, not shown, drives a pinion 1 secured to a staff 0 to which is fixed the minute wheel 3 driving the minute-hand sleeve 6. Pinions 4, 2 are also secured to the staff 0, the former 4 driving the hour-hand sleeve and the latter driving a wheel 12 connected to the date - indicating mechanism. The device is set either by a crown wheel engaging the wheel 12 or by a key engaging the squared end of the staff 0. Specification 486,874, [Group XIX], is referred to.
