Abstract

2137. Schwan, K. Jan. 27. Driving-mechanism, spring; going-trains.-In a clock which requires winding only at long intervals, the barrel a is mounted on ball bearings a' to reduce friction. The transmission ratios in the going-train are very large, so that as few wheels as possible may be employed.
