Definitions

  • FIGURE 1 is a fragmentary plan view of a watch de signed according to the present invention
  • FIG. 2 is a fragmentary plan view of the watch, shown at an enlarged scale
  • FIGS. 3 and 4 are diagrammatic views demonstrating the operation of the mechanism of the watch shown in FIG. 1;
  • FIG. 5 is a section along the lines 5-5 of FIG. 1, but on a smaller scale.
  • two pawls 20 and 21 pivoted on an oscillating mass 22 drive a ratchet wheel 23 disposed coaxially with the barrel (not shown) of the watch, the axis 24 of which is indicated in FIG. 2, the ratchet wheel 23 rotating the barrel (not shown.)
  • the two pawls 20 and 21 are approximately parallel and their respective pivot points 27 and 28 are disposed on the mass 22 and in particular on a part 29 of the mass 22 lying inside an arc of a circle 30, the center of which coincides with the center of the movement and which passes through the center of rotation 25 of the mass 22.
  • the pawls 20 and 21 are held elastically in engagement with the ratchet wheel 23 by springs (not shown) and the mass 22 is shaped in such manner as to be able to pivot about the pivot 25 through an angle y.
  • the pivot 25 of the mass 22 is formed by a pivot member 30 which rotates in ballbearings 31 and 32, the first of which is supported by 9.
  • the part 35 of the mass 22, carrying the pivot 3%, has lateral cavities intended for the passage of the lug 3-3 and of the bridge 34 while the remainder of the mass 22 surrounding the movement has a thickness approximately equal to the thickness of the latter.
  • the illustrated pawl mechanism occupies a minimum of space and may be constructed in such manner that the oscillation of the mass 22 corresponds exactly to an advance by one tooth of the wheel 23.
  • the wheel 23 will, for example, have a diameter of 9.2 millimeters and teeth, which gives a circumferential pitch of its teeth of about 0.16 millimeter.
  • This drive of the wheel 23 with very small advances dispenses with a reduction gear and facilitates the obtaining of a very flat watch.
  • the watch according to the present invention may also contain a movement of a shape other than circular.
  • the mass can also be formed as a part of the case of the watch in relation to which the movement oscillates.
  • a wristwatch including a movement
  • said movement having a spring barrel and an automatic winding mechanism
  • said winding mechanism comprising an oscillating mass of substantially annular configuration surrounding said movement
  • pivoting points of said pawls being disposed at opposite sides of and adjacent to an imaginary line extending through the center of rotation of said mass and substantially tangentially to said ratchet wheel,
