Definitions

  • the present invention relates to setting and winding mechanismfor watches, which essentially is characterized by the fact that it comprises a winding rod or push stem which is arranged radially in a plane parallel to the plate of the :movement, said stem carrying a single pinion and being adapted to slide longitudinally in order to bring the pinion into gear either with a :crown wheel for winding or with a setting gear, members being provided for regulating the meshing motion of the said pinion in both of its possible positions.
  • Figures 1 and 2 are plane views of a first working form
  • Figure 3. is a section along the line III-III of Figure 1:;
  • Figure 4 is a plane view of a second-working form;
  • Figure 5 is asection along the line IIII of Figure 4 and Figure 6 is a detail view.
  • the winding stem 10 is arranged radially on the rear face of the plate 11 and in a plane parallel to the latter. It is secured in vplace @by a member 12 fixed to the plate 11 and is adapted to slide longitudinally in said member 12.
  • a spring 13 is provided on the member 12; the end 14 of said spring alternatively engages in two circular grooves 15 and 16 of the stem 10, depending on the position into which the latter is brought.
  • the stem 10 carries on one of its ends a pinion 17 which meshes either with a crown wheel 18 or with a setting gear 19 just as the end 14 of the spring 13 meshes either with the groove 15 or with the groove 16.
  • a detent 20 turns on a pivot 21 of the member 12.
  • This detent 20 is provided with two beaks 22 and 23, of which beak 22 is in contact with the inner face of the pinion 17, whilst the beak 23 enters into the groove 16 of the rod 10.
  • the free end 24 of the detent is equally displaced and slides freely between the portion 25 of the member 12 and the plate 11.
  • the end 24 of the detent 20 presents a projection 26 constituting an in-,
  • winding stem 10 needs not necessarily be arranged on the rear face of the plate 11.
  • the stem 10 at the end of which is fixed the pinion 17 is arranged radially on the rear face of the plate 11 and in a plane parallel to said plate. It is held in place by a bridge 12 fixed to the plate 11 and is adapted to slide longitudinally between these two two circular notches or grooves 15 and 16 into which alternatively penetrates the end 14 of a sliding member 14 submitted to the action of a spring 13 fixed to the bridge 12.
  • a detent 20 is pivoted on an axle 21, arranged coaxially with the axle of the pawl 27 of the clockwork upon which is fixed small pin 28 which traverses an opening 29
  • the winding stem 10 presents.
  • the spring 13 and to the sliding member 14 is such that normally the member 14 is free to slide whenever the winding rod 10 is displaced longitudinally from one groove, say for instance 15, into the groove 16.
  • the detent 20 is adapted to be displaced through a small recess of the spring 13 so as to be brought in front of the sliding member 14 which for this reason may no longer be displaced in longitudinal direction. This is the position as represented in Fig. 6 of the drawing.
  • time indicator is either to be wound or if it is to be set to time the winding rod or push stem is longitudinally displaced in such a manner as to make the pinion 17 engage with a crown wheel 18 or with the set ting gear respectively (not shown in the drawing) the end 14 of the member it passing in this latter case from groove 15 into groove 16.
  • the spring 30 besides secures and facilitates the function of the pawl if during winding apull is exercised on the winding rod or push stem.
  • the winding parts are'much more distant from the dial than in ordinary watches. This feature is particularly advantageous in watches for automobiles if it is desired to place the watch in-the rear of the dashboard and if this latter is of a certain thickness as is the case when made of wood.
  • winding and setting pinion carriedby said spindle, a pawl actuated incident to winding the watch, and means coacting with said pawl to prevent axial displacement of the spindle during the winding operation.
  • a winding spindle movable axially to winding and setting positions, a winding and setting pinion carried by said spindle, a pawl actuated incident to winding the watch, and means coacting with said pawl to prevent axial displacement of the spindle during the winding operation, said last mentioned means including a pivotally mounted member having an inclined extremity and a pin carried by said pawl adapted to include the said inclined extremity during the winding operation.
