Abstract

179,453. Baker, T. R. June 10, 1921. Securing toothed wheels on shafts.-In gearing for clocks, watches, speedometers, gramophones, &c., a toothed wheel b having a circular bore c is secured by a driven fit on its spindle a, which is formed with longitudinal grooves a<1> capable of serving as pinion teeth. The ends of the spindle a are turned down to constitute journals a<2>, and a gap d may be formed if necessary, to clear another member of the gear-train. The arrangement permits the wheel b to be turned over when the working-flanks of its teeth are worn, or to be shifted axially when it has worn a groove in the pinion with which it engages.
