Definitions

  • This invention relates to watches and more especially to watches equipped with means for effecting winding of the main spring upon movement of the watch.
  • An object of this invention is a self-winding watch provided with improved and etlicient means for efi'ecting winding of the main spring upon movement of the watch and preventing overwinding of such spring.
  • a Watch embodying the invention is provided with a weighted pendulum which is caused to oscillate by movement imparted to the watch, usually while being worn.
  • a ratchet wheel or the like is geared to the winding train of the watch and the pendulum is provided with a pawl by means of which unidirectional rotation is imparted to the ratchet wheel upon oscillation of the pendulum.
  • the pawl is mounted on the pendulum in such a manner as to be capable of linear movement relatively thereto and resilient means are provided tending to maintain the pawl in enga ement with the teeth of the ratchet wheel.
  • Fig. 1 is a rear view of a watch embodying the invention.
  • Fig. 2 is a similar view somewhat enlarged of the pendulum, ratchet wheel and pawl.
  • Fig. 3 is a side view of Fig. 2
  • Fig. 4 is a view similar to Fig. 2 of a modified embodiment of the invention.
  • the case 10 may be of any suitable (i sign and within it is suitably mounted the watch movement 11.
  • the main spring gear wheel 12 is connected through a suitable winding train with a ratchet wheel 13, rotation of which in one direction is prevented by a pawl 14.
  • a weighted pendulum 15 is pivotally supported co-axlally with the ratchet wheel 13 and a lever 16 is mounted on the pendulum by means of a pivotedpin 16.
  • the lever 16 pivotally supports a pawl 17 which is adapted to engage the teeth of the ratchet wheel 13 and which is pressed into operating position by a spring 18.
  • a leaf spring 19 is attached at one end to the pendulum and its other end bears against the lever 16 to maintain said lever in contact with the pin 20 carried by the pendulum.
  • the pendulum 15 is provided with a series of sockets adapted to receive a in 21 by means of which the tension exerted y the spring 19 on the lever 16 may be varied.
  • Resilient abutments 22 are provided to be engaged by the enlarged portion of the pendulum 15 to cushion the pendulum at either end of its stroke.
  • the pendulum 15 has mounted thereon, by a pivot pin 16 a lever 16' provided with a resilient extension 19 which enga es the surface of an eccentric adjusting member 21.
  • a pawl 17 is pivoted to the lever 16 and is pressed by spring 18 into engagement with the teeth of the ratchet wheel 13.
  • the pendulum is provided with a pin 20 against which the main portion of the lever 16 is held by reason of the engagement of the projection 19 with the ad 'usting member 21.
  • the operation of this em' odiment is similar to the operation of the embodiment disclosed lever to press the latter into engagement with in Figs. 1 to 3 inclusive.
  • I11 a self-winding watch, a pendulum, a ratchet wheel, a lever pivoted to said pendulum, a pawl carried by said lever to cooperate with said ratchet wheel, and resilient means tending to maintain predetermined relation between said pawl and pendulum.
  • a pendulum In a self-winding watch, a pendulum, a ratchet wheel, a lever pivoted to said pendulum, a pawl carried by said lever to cooperate with said ratchet wheel, resilient means tending to maintain predetermined relation between said pawl and pendulum, and means for varying the tension of said resilient means.
  • a pendulum In a self-winding watch, a pendulum, a ratchet wheel, a lever pivotally supported by said pendulum, a pawl carried by said lever and being adapted to engage the teeth of said ratchet wheel, a stop carried by said pendulum, and a resilient member tending to maintain said lever in contact with said stop.
  • a pendulum In a-self-winding watch, a pendulum, a ratchet wheel, 'a lever pivotally supported by said pendulum, a pawl carried by said lever and being adapted to engage the teeth of said ratchet wheel, a stop carried by said pendulum, a resilient member tending to maintain said lever in contact with said stop, and an adjustable member for varying the tension of said resilient member.
  • a pendulum In a. self-winding watch, a pendulum, a ratchet wheel, a pawl supported by said pendulum for linear movement relative thereto, a leaf spring attached at one end to said pendulum and having its free end tending to maintain predetermined relation between said pawl and pendulum.
  • a pendulum In a self-winding watch, a pendulum, a ratchet wheel, a pawl supported by said pendulum for linearmovement relative thereto and adapted to cooperate with said ratchet wheel, a leaf spring attached at one end to said pendulum and having its free end tending to maintain predetermined relation between the pawl and pendulum, and a row of recesses in said pendulum adapted to receive a pin to be engaged by said spring whereby the tension thereof is varied.
  • a pendulum In a self-winding watch, a pendulum, a ratchet wheel, a lever pivotally supported by said pendulum, a pawl pivoted to said lever, resilient means tending to maintain said pawl in engagement with the teeth of said ratchet wheel, a stop carried by said pendulum, a leaf spring attached at one end to said pendulum Y and having its free end bearing against said said step.
