Abstract

534,672. Chronographs. SOC. INDUSTRIELLE DE SONCEBOZ SOC. ANON. Sept. 19, 1939, No. 26164. Convention date, Aug. 22. [Class 139] Stop mechanism.-A time piece with a chronograph mechanism has an operative connection between the two mechanisms which includes a sun and planet differential gear under the control of a manipulative member to start, stop and re-set the chronograph indicator. The seconds spindle of the time-piece is connected by a gear train 1 ... 5 Figs. 1 and 2, to the first sun wheel 7 of the differential gear loose on a spindle 6. A second sun wheel 8 also loose on the spindle is connected to the first sun wheel 7 by a pair of planetary gears 9, 10 supported on a disc 13 secured to the spindle 6. The spindle 6 carries a heart shaped cam 14 and an indicating pointer 6a and the sun wheel 8 is formed with a disc 8a. Mounted on a shaft 15 are a pair of retaining levers 16, 17 for cooperation with the discs 8a and 13 respectively and a resetting lever 18 for co-operation with the heart cam 14. These levers are operated by a single button 19 with controlling cams 20, 21, 22; with the button in the stop position the lever 17 holds the disc 13 and planetary gears stationary; in the operative position the lever 16 holds the disc 8a and the planetary gears convey the movement to the pointer 6a.
