Definitions

  • the present invention relates to a watch movement with ringing mechanism, comprising an alarm releasing device adapted to release the alarm at a predetermined moment, then to stop it, and to release it again.
  • the present invention has for its object to make good this loss.
  • the releasing device comprises two distinctive releasing members adapted to be adjusted at will one with respect to the other for releasing the alarm, the first of said members for a first alarm period at a determined moment and the second for a second alarm period after a freely adjustable time interval.
  • FIG. 1 shows a part of an axial section through the watch movement according to the invention
  • FIG. 2 is a top view of the device for releasing the alarm in an operating position
  • FIG. 3 is a top view of the same device but in another operating position
  • FIG. 4 is a top view of still the same alarm releasing device in a third operational position
  • FIG. 5 is an elevational view of an alarm watch provided with a movement according to the present invention.
  • the movement illustrated in FIG. 1 comprises a thin plate 1, a bridge 2 extending parallelly to said plate and situated underneath of it, and a dial 3 extending above of the' plate 1 at a determined distance thereof, some of the train elements of the movement being arranged between the plate and the dial.
  • the power necessary for driving the movement and the alarm mechanism is accumulated in a motor barrel 4 comprising a motor spring 5.
  • the inner end of spring 5 is hooked to a barrel-arbor 6 pivoted in a bearing 7 on bridge 2, on the one hand, and in the center portion of the drum of barrel 4 on the other hand.
  • the barrel-arbor 6 carries a retaining means 8 forming the cover of the barrel and cooperating with a Breguet or saw toothing 9 at the inner face of bridge 2.
  • the drum of barrel 4 moreover is pivoted in a bearing 10 of the plate 1.
  • This drum has an outer toothing 11 meshing with a first train element (not represented) of a gear train comprising an escape wheel cooperating with a contventional regulating device with a balance.
  • the drum of barrel 4 further carries a driving wheel 12 secured to the end of its arbor and extending into the space between the plate 1 and the dial.
  • This driving wheel actuates the indicating means of the alarm as well as the ringing mechanism in the following manner:
  • the wheel 12 meshes with a transmission wheel 13 which in turn is frictionally coupled to a disc 14 having a peripheral toothing of same diameter as the toothing of the wheel 13.
  • This disc 14 in turn meshes with an hour wheel (not shown) of conventional construction arranged in the center of the movement and carrying the hourhand 15 (FIG. 5).
  • This wheel further entrains a minutewheel meshing with a canon-pinion carrying the minutehand 16 coaxially to the hour-hand 15.
  • the frictional coupling between the elements 13 and 14 aifords for the hand-setting of the hands 15 and 16.
  • the dial 3 is provided with a chapter ring 17 visible from the exterior.
  • the barrel 4 regulated by the gears and the regulating device, rotates at a speed of one revolution in 12 hours.
  • the gear elements 13 and 14 having a diameter that is double the one of wheel 12 thus effect one revolution in. 24 hours.
  • the hour wheel has the same diameter as the wheel 12.
  • the wheels 13 and 14 rotate in counter-clockwise direction while wheel 12 rotates in clockwise direction.
  • a winding button secured to the end of the barrel-arbor 6 serves to wind the spring 5. It appears from FIGURES 1 and 5 that the dial 3 has an opening 18 of circular shape situated in the zone of 6 oclock and through which the upper face of disc 14 is visible. This upper face carries a crown 19 marked from 0 to 24 hours.
  • a stationary index 20 thus indicates the time in the double hour circle.
  • the elements 13 and 14 pivot on a shaft 21 guided in a bearing 22 of bridge 2 and in an opening 23 of plate 1.
  • This shaft extends to the rear side of the movement where it is accessible. It carries a cap 24 resiliently engaged on its upper end owing to a slot 25.
  • This cap which rotates with shaft 21 is engaged in a sleeve 26, which in turn is engaged in co-axial openings of the elements 13 and 14.
  • the cap 24, the sleeve 26 and the elements 13 and 14 are frictionally adjusted on each other and may rotate independently from each other.
  • the sleeve 26 carries at its upper end an indicating member 27, which extends above of disc 14 and the cap 24 carries an indicating member 28, which extends above of the indicating member 27.
  • Both said indicating members normally rotate with the disc 14 entrained by the movement, but may be adjusted at will with respect to said dial disc and placed either in coincidence or with an angular spacing between 0 and a maximum value.
  • the indicating member 27 is in advance of the member 28 in the direction of rotation of disc 14.
  • the ringing of the alarm watch is released when the member 27 is opposite index 20. It stops automatically after a determined period and is again released when the indicating member 28 comes opposite to index 20.
  • the releasing mechanism which ensures these functions primarily comprises a cam 29 mounted for rotation with the cap 24 and the shaft 21.
  • the cap 24 comprises at its lower end a pair of noses 30 diametrically opposite to each other and engaged in corresponding recesses provided on the lower face of cam 29.
  • the mechanism further comprises a releasing wheel 31 engaged on the lower end of the sleeve 26 which presents a flat portion 32 to which corresponds a straight portion of the contour of the center opening of wheel 31 so that the driving connection of sleeve 26 and of wheel 31 is ensured.
  • a resilient disc 33 presenting at its periphery upstanding tongues 34 engaged in a Breguet toothing 35 provided at the lower face of wheel 13.
  • Disc 33 rests on wheel 31 and has an opening engaged by a catch 36 projecting from wheel 31.
  • Disc 33 connected for rotation with wheels 31 forms a unidirectional coupling between this wheel and the transmission wheel 13 and as the latter is constantly engaged with the wheel 12 entrained by the barrel, the releasing wheel 31 may be displaced with respect to wheel 13 only in forward direction, i.e. in counter-clockwise direction as seen in FIGURE 5.
  • the wheel 31 further has at its lower face a pair of stops 37 and 37a arranged on both sides of cam 29 so that when shaft 21 is rotated in counter-clockwise direction the cam 29 abuts the stop 37 and entrains wheel 31 and disc 33 the tongues of which slide on the Breguet toothing 35.
  • the relative position of cam 29 and of wheel 31, which in this manner is determined by the first stop 37, corresponds to that in which both indicating members 27 and 28 are placed one above the other.
  • disc 33 ensures the frictional coupling between the wheel 14 and the wheel 13. Since wheel 14 .is axially retained by a collar of sleeve 26, while cam 29 is axially retained by the catches 30, the resilient disc 33 rests on wheel 31 and presses the latter against cam 29 while compressing the wheel 13 against wheel 14 as the cap 24 axially retains sleeve 26.
  • FIGURE 1 A shaft 38 pivoted between the bridge 2 and the plate 1 and extending into the space between the plate 1 and dial 3 carries and rotationally drives a control disc 39 on the hub of which is mounted a collet 40 to which is attached the inner end of an alarm spring 41.
  • the outer end of this alarm spring is attached to a pillar 56 projecting from plate 1 in direction to bridge 2.
  • the disc 39 may slide on shaft 38. It presents in the inner face of its hub a Breguet toothing 42 engaged by a corresponding toothing of an alarm wheel 43 mounted for free rotation on the lower end of shaft 38.
  • a spring plate 44 maintains the Breguet toothings 42 engaged with each other in such manner that when shaft 38 is rotated by spring 41 after winding and releasing of the alarm, the wheel 43 is entrained by the Breguet toothing 42 and rotates an escape wheel 45 actuating by means of a pallet (not represented) a ringing hammer.
  • a winding wheel 46 provided at its periphery with a toothing 47 and carrying on its lower face a stop 48.
  • the toothing 47 of wheel 46 extends at the level of the releasing wheel 31 and the stop 48 extends at the level of cam 29.
  • the manner in which these elements cooperate is represented on FIGURES 2, 3 and 4. While the toothing 47 extends on the whole periphery of wheel 46the toothing of the releasing wheel 31 extends only about 320 and comprises a last tooth 49 which is reinforced.
  • Cam 29 further has an ear limited by a radial face 50 abutting against stop 37 when the indicating members are brought tov coincide and a peripheral edge 51 of slightly spiral form for facilitating the displacement of the cam under: the action of stop 48.
  • the unit of the ringing block continues to be entrained owing to the meshing of gear element 13 with gear element 12 and to rotate in counterclockwise direction.
  • the first tooth 52 of the releasing wheel 31 comes to engage toothing 47 and entrains gear element 46 (FIG. 3).
  • the alarm spring is thus automatically wound in clockwise direction from the power communicated by the barrel 4 and this winding will last until the gear elements 29 and 31 are again in the position shown in FIGURE 2, i.e. 24 hours later where a further alarm will be released.
  • cam 29 the edge 51 of which would present several steps and a wheel 46 provided with several stops so that each alarm could be divided into several periods. It would also be possible to provide several cams adjustable with respect to each other and affording for the releasing of several alarms at determined time intervals.
  • the described ringing mechanism is further provided with a blocking system for stopping the ringing once it has been released.
  • This system comprises a lever 53 adapted to stop the hammer and provided at one end of one of its arms with 'a stud 54 sliding in :a slot 55 of gear element 39 and which, when the alarm spring 41 starts to be wound, again returns the blocking system into its starting position.
