Description

United States Patent 2,785,529 TIMEPIECE AUTOMATIC REGULATOR Hans Haerri, Les Bioux, Switzerland, assignor to Benrus Watch Co. Inc., La Chaux-de-Fonds, Switzerland, a firm of Switzerland Application October 22, 1954, Serial No. 464,132 7 Claims. (Cl. 53-109) My invention has for its object a time-piece including means for automatically adjusting the regulating lever when setting the time-piece right. According to my invention, I provide a winding-up stem adapted to occupy selectively three operative positions, to wit a winding up position, a time-setting position and a third position for which the time may be set right in a manner such as will adjust the regulating lever. This is provided by two levers one end of one of which is operatively connected with the regulating lever while its other end carries teeth, the second lever pivotally secured to the first lever is controlled by the winding up stem; the arrangement is such that when the stem is brought into its third operative position, the teeth on the first lever mesh with the cannon pinion so as to make the latter shift the regulating lever.
I have illustrated in accompanying drawings a preferred embodiment of a time-piece according to my invention. In said drawings:
Fig. 1 is a front view of a time-piece seen from its dial side, after removal of all but a fragment of the dial.
Fig. 2 is a partly cross-sectional side view of Fig. 1 through line IIII thereof.
As illustrated, the time-piece includes a winding up stem 1 controlling the conventional pusher member 2 carrying a stud 3 cooperating with a spring blade 4; the said spring blade is provided with three recesses 5, 6 and 7 adapted to be engaged selectively by the stud 3 when the winding up stem is shifted longitudinally. Engagement of the stud by the notch 5 allows winding up the time-piece, by the notch 6 ordinary time-setting and by the notch 7 time-setting associated with automatic adjustment of the regulating lever.
The center wheel or driving Wheel is shown at 8, the cannon pinion at 9 and the regulating lever at 10, the tail piece 11 of said regulating lever carrying a pin 12 passing vertically throughout the timepiece. A lever 13 is provided at one end with a toothed sector 14 and at its other end with a slot 15 inside which the pin 12 is adapted to slide. Said lever 13 is pivotally secured at 16 to a second lever 17 which in its turn is pivotally secured at 18 to a screw fitted in the case of the time piece, the lever 17 being adapted to move in a plane parallel to the general plane of the timepiece. The outer end 19 of the lever 17 forms a sloping surface engaged by the stud 3 on the pusher member; a return spring 17a urges the lever 17 towards the stud 3. As shown, the levers 17 and 13 are arranged on the dial side of the timepiece to move in planes parallel to the general plane of the timepiece, and the regulating lever is arranged on the opposite side of the timepiece to move in a plane parallel to the general plane of the timepiece.
When the winding up stem 1 is shifted to the illustrated position, the lever 17 moves the toothed sector 14 of the lever 13 radially with respect to the cannon pinion 9 into meshing relation with said pinion. In the position illustrated, the stud 3 engaging the notch 7,
the pusher member and the winding up stem are in the position allowing the setting right of the time-piece with an automatic adjustment of the position of the regulating lever. The lever 17 holds, in this case, the toothed sector 14 of the lever 13 in mesh with the cannon pinion 9. When the latter is shifted so as to set the time right, it causes the lever 13 to rock and thus to alter the position of the regulating lever whereby the future operation of the time-piece is adjusted.
The movements of the regulating lever are limited by reason of the pin 12 being guided inside the groove 20 formed in the case; the peripheral length of the toothed sector 14 corresponds to the maximum allowed movement of the regulating lever so that said sector cannot be angularly shifted to a further extent when the cannon pinion is moved beyond a predetermined angular position. The lever 13, by means of the pin 12 and slot 15, is slidably connected to the tail piece 11 of the regulating lever whereby movement of the lever 13 into and out of meshing relation with the cannon pinion 9 does not affect the movement of the regulating means.
When the Winding up stem is returned into the position corresponding to conventional time-setting, with the stud 3 engaging the notch 5 or into the position corresponding to winding up with the stud 3 engaging the notch 5, said stud 3 on the pusher member acts on the sloping surface 19 of the lever 17 so as to shift the toothed sector away from the cannon pinion.
