Abstract

1394073 Chronographs BAUMGARTNER FRERES S A 26 May 1972 [17 June 1971] 24893/72 Heading G3T A chronograph comprises a drive transmitting member 2 which is loosely mounted on a chronograph hand shaft 6 and is pressed into engagement with a heart-shaped cam 7 fixed to the shaft by a spring 5 acting between the member 2 and a coupling member 1' which is fixed for rotation with the member 2 but axially slidable thereon and which is pressed by the spring into engagement with a fourth wheel 4. The latter carries a conventional seconds hand 4". Operation of a pusher 9, Fig. 2 (not shown) closes fork arms 10, 11 to raise the coupling member 1 from wheel 4, and a lever (12) coupled to the arm 11 is brought into engagement with cam 7 to return the chronograph hand 13 to zero.
