  • Lever 26 is articulated at 27 on the frame and carries, articulated at 28 thereon.
  • an oscillating lever 29 called the "reverse le ver.”
  • Lever 2 is provided with two beaks 29a and 2912. the purpose of which will be described hereafter; a spring 30. carried by the control lever 26. maintains. at rest. the reverse lever 29 in the position represented in FIG. 1.
  • the other control lever. designated by 31. is articulated at 32 on the frame and operates to effect the return to lero operation.
  • the two control levers 26 and 3]. respectively. on which act buttons which have not been represented. and which are carried by the casing of the watch. are situated on both sides of the axis of the winding and setting stem 33, visible in FIG. 4a.
  • the said axis is itself designated by 33 in FIG. I.
  • the two bearing surfaces 34 and 35 of the two control levers 26 and 31 are symmetric with respect to the stem 33.
  • the control mechanism of the chronograph comprises a cam including of three superposed elements 36, 37 and 38 one with each other. by weldment. for example.
  • the said cam has thus three levels and there fore can operate elements positioned at different levels.
  • the cam is rotatably mounted on a collar 39a of the hub 39 of the crown wheel 40. Wheel 40 meshes with the winding pinion 41 carried by the stem 33.
  • the three-clement cam 36-37-38 is held in place on the col lar 39a and a screw 42 (FIGS. 1 and 4a).
  • the axis of the collar 39a. and consequently the axis of rotation of the three-element cam. intersects the axis of the winding and setting stem 33.
  • the action of the lower element 38 of the threeeleinent cam is controlled on the one hand by the reverse lever 29 and on the other hand by the control lever 31; such control permits rotativc movements. in one sense or in the other. ofthe cam; the action of the element 38 is also controlled by a jumpenspring 43 which cooperates with one or the other of three slots 44, 45 and 46 of the element 38. according to the position of the cam.
  • the element 38 operates a lever 47, the head 47a of which. is engaged in a slot 48 ofelement 38 and is artic ulated at 49 on the frame.
  • the purpose of said lever 47 will be discussed hereafter.
  • the lower element 38 of the cam also operates a brake 50, articulated at 5] on the frame. by means on a slot 52 of the element 38. Slot 52 acts on a nose 50a of the brake.
  • the brake 50 is in tended to cooperate. by means of its shoe 50h. with the wheel 1 of the chronograph.
  • the intermediary element 37 of the three-element cam operates the clutch lever S by means of a nose 37a acting on an arm 5b of the lever 5.
  • the upper element 36 of the cam operates the hammer ll) of return to zero.

Consequently, if a force or pressure is exerted, as indicated by the arrow 57 in FIG. 3. on the bearing surface 34 of the control lever 26. the nose 29a of the reverse lever 29 acts on the bearing surface 56 of the element 38 of the cam for rotating the cam in the clockwise direction and bringing it into the position represented in FIG. 3, in which the jumper 43 is engaged in the slot 46 of the element 38 of the cam. It is to be noted that, in the course of reaching this position, the cam has passed over its intermediary position (shown in FIG. 1) without stopping therein.
  • the last named position of the cam corresponds to the running of the chronograph: In this position. the oscillating pinion 2 is engaged in the toothing of the wheel ofchronograph l and the brake 50b is separated from this wheel. The hammer I0 is lifted by the element 36 of the cam.
