Abstract

5310. Hartmann, F., and Olißk, J. March 14. Going-trains.-A watch is made which requires winding-up only once a week, but in which the length of the mainspring is still normal. The ratios of the wheels and pinions give four hours for the revolution of the centre-wheel G and a quarter of an hour for the revolution of the third wheel Z. The centre-arbor extends through the hollow arbor of the centre-wheel and carries at the back a second centre-wheel M<2> in gear with a wheel M<1> of one-fourth the size on the third arbor. Motionwork.-Instead of having a cannon pinion, the centre-arbor and second centre-wheel M<2> are connected by a friction clutch P.
