Definitions

  • ABSTRACT A mechanism'for setting the date-indicating indicia on a calendar watch' including a date-setting mechanism having an inactive position and at least one first active position, said setting mechanism causing the date- 7 indicating indicia to advance by one step into the first active position immediately after the date-indicating mechanism has been brought to a position correspond- 1 ing to the date 31.
  • Special watches are also known, of which the calendar is so designed as to stay up-to-date for several years.
  • Such watches are provided with mechanisms of a complicated nature and for instance comprise a cam of essentially circular shape and so activated by the movement as to complete one revolution every four years.
  • This cam is. provided on its periphery with 48 notches each corresponding to. one of the months of the 4-year period under consideration; the depth of each notch determines the time and the extent of the date-setting effected by the calendar indicating member.
  • the purpose of the present invention is to create a calendar watch no longer requiring its user to set the date at the end of those months with fewer than 31 days and lacking complexities such as would prevent widespread marketing.
  • the object of the present invention is a watch with a calendar mechanism comprising a dateindicating mechanism and a commuting member driven by the movement and activating said indicating member every 24 hours. It is characterized by an automatic date-setting mechanism with an inactive position and at least one first active position, said date-setting mechanism causing the indicating member to move forward by one step into the first active position immediately after the indicating member has been brought into the position corresponding to the date 31 by the commuting member.
  • the automatic correction mechanism may be previouslyprogrammed and its adjustment is less complex than'that of the perpetual calendar watches mentioned above.
  • FIG. 1 is a plan top view of the date setting mechanism according to the first embodiment
  • FIG. 2 is a section on a larger scale, along line IIII of FIG. 1,
  • FIG. 3 is a view similar to that of FIG. 1, showing a second position of the date-setting mechanism
  • FIG. 4 is a view similar to FIG. 1 for the second embodiment
  • FIG. 5 is a fragmentary section of a detail of the second embodiment, along line V-V of FIG. 4, on a larger scale,
  • FIG. 6 is a view of the second embodiment in another active position, g
  • FIG. 7 is a view analogous to FIG. 1, for the third embodiment
  • FIG. 8 is a fragmentary section on a larger scale of a detail of the third embodiment and FIG. 9 is an over-all view of the watch according to the first and third embodiments.
  • FIG. I shows a wrist-watch movement, the bottomplate of which holds a date-indicating ring 2 co-axial with the bottom-plate. and activated every 24 hours by a commuting member 3 itself provided with a radial finger-piece 4 engaging the toothing 5 of the dateindicating ring.
  • the commuting member 3 pivots round a fixed axis; itshub is mounted on a collet of bottomplate 1 as shown in FIG. 2 and is driven by settingwheel 6 and wheel-and-pinion 7 from the hour-wheel 8 which is normally emplaced at the center of the movement. As seen from FIG. 2, this hour-wheel is fastened on cannon-pinion 9.
  • the wheel-and-pinion 7 comprises two co-axial toothings, the lower one of a diameter half the upper ones, so that commuting member 3 rotates at the rate of one revolution every 24 hours.
  • Setting wheel 6'and wheel-and-pinion 7 are provided with central openings fastened on corresponding collets in the bottom-plate or on the pegs fastened to this frame element.
  • Plate 10 (not shown in FIG. 1) extends above setting-wheel 6 and in between the two toothings of wheel-and-pinion'7 so as to maintain those members in place axially.
  • control plate 12 of circular periphery and co-axially located with respect to member 2 above the date setting mechanism imminently to be described rather than being axially retained in place by the stepped screw 11.
  • Screws l1 and 13 the latter diametrically opposed to the former and also screwed into the bottom-plate 1 so maintain in place the command member 12 that the latter may be rotationally displaced between two positions defined by the end of slots 14 and 15 through which pass the shoulders of screws 11 and 13.
  • the shoulders of these screws are so adjusted that plate 12 may freely rotate about its axis.
  • a spring 16 pushing on a pin 17 constantly pulls on plate 12 towards the position shown in FIG. 3, i.e., towards the inactive position.
  • plate 12 is held back by one of the three arms of star 18 which functions in concert with pin 19 which in turn is mounted on plate 12.
  • a six-teeth ratchet wheel ganged to star 18 and functioning in concert with the inside end of the push-piece 20 allows step wise rotation of this star 60 degrees at a time so that pin 19 alternately is located at the end of one of the arms of star 18.or in'the hollow between two of those arms, so that plate 12 alternately passes from the active position to the inactive one.
  • plate 12 moves a control lever 21 which is located in a recess of bottom plate 1 and the inside end of which supports a peg 22; date-setting member 23 which rotates about peg 22 is provided with a radial finger-peg provided by the bottomplate; this peg at the same time serves as a pivot axis for a setting-wheel 25 connecting the commuting member 3 to date-setting member 23, so that these two members are constantly engaging one another even though the date-setting member moves in accordance with the position changes of lever 21. Because of the existence of setting wheel 25, both members 3 and 23 obviously rotate at the same speed.
  • member 23 When in that position, member 23 will continue rotating about itself and therefore it remains oriented in the same manner with respect to commuting member 3 without however activating anything.
  • the latter may bear the numbers 30 and 31, one corresponding to the active position and the other to the inactive position, and these numbers may successively appear in a window 32 shown in FIG. 9 and located at 6 oclock.
  • push-piece 20 may be located at 2 oclock, the winding stem at 4 oclock and the latter also bearing crown 33.
  • the date window 34 in that case may be located at 3 oclock.
  • FIGS. 4, 5 and 6 show an embodiment generically conceived from the same principle but allowing the programming of date-setting not only for the end of a month of 30 days but also forthe end of February when holding 28 days or when holding 29 days in leap years.
  • This embodiment again comprises date ring 2 and commuting member 3 with its finger piece 4 functioning in concert with toothing 5 of ring '2.
  • this embodiment comprises jumper 28 and setting-wheel 6, wheeland-pinion transmission 7 ensuring reduction in the ratio of 2 to l, and hour wheel 8.
  • control member 12 has been replaced by a circular plate 35 which though axially retained in place by the two screws 11 and 13 engaging the clearances 14 and 15 may be subject to a rotational shift of much larger amplitude than plate 12, the two recesses 14 and 15 being longer.
  • the contour of the cen tral opening of plate 35 is provided with three notches 36, 37 and 38 between which extend two segments in the shape of arcs of circle of the same radius rather than the single notch 26 of plate 12. The whole of this profiled contour section of the central opening of plate 35 is bounded by two nearly radial segments acting as stops.
  • the mechanism now comprises three levers 39, 40 and 41 each provided at its inward end with one of the three date-setting members 42, 43 and 44. These levers each pivot round an axis coinciding with that of the setting wheels 45, 46 and 47. Further, each of the three levers 39, 40 and 41 carries a roller 48, 49 or 50 at its outward end and is pulled by a spring 51, 52 and 53 in such manner that this roller pushes against the periphery of ring 2.
  • the control member 35 is ganged to a toothed sector 54 which meshes with a setting wheel 55 itself co-axial with screw 13. In lieu of being controlled by push-piece 20, this member is controlled by a stem 56 and pinions 57 and 58, the latter meshing in with the setting wheel 55.
  • the spring pawl 59 ensures achieving the four angular positions corresponding, the first to the inactive position, the second to the first active position in which it is the axis of date-setting member 42 that may engage hollow 36, the third (shown in FIG. 4) corresponding to the second active position in which the date-setting member 43 is in a position to engage toothing 5 because its axis has entered notch 37, and the fourth (FIG.
  • the desired date-setting operations are effected with the three hollows 60,61 and 62 in the date-ring periphery; they function in concert with rollers 48, 49 and 50 and with finger-pieces mounted on the date-setting members.
  • member 42 is provided with a finger-piece 42a, member 43 with two finger-pieces 43a and 43b, and member 44 with three finger-pieces 44a, 44b and 44c.
  • the exterior edge of date ring 2 is profiled as illustratively shown in FIG. 5, which shows a cross-section through this ring and further shows lever 41 with its roller 50 pushing against this ring 2.
  • the section of ring 2 shows two fairly deep grooves defining three parallel ribs. These window each one day apart. The next month, one will have to move plate 35 in such fashion that the spring pawl 59 will be brought into its second notch. Therefore, it shall be the axle of the date-setting member 42 which will be opposite notch 36, and when the date 31 shall appearin the window, roller 48 will drop into the ribs stretch along the entire periphery of the ring, but
  • the hollow 62 is machined in the upper rib, hollow 61 in the middle rib and hollow 60 in the lower rib;
  • rollers 48, 49 and 50 they are mounted on reduced diameter axles and are'each located at the particular height of one of the three ribs.
  • that command lever carrying a date-setting organ the axis of which is opposite one ofthe notches 36, 37 and 38 may move under the influence of its spring and bring the date-setting organ near the toothing 5, but such motion may only occur when the hollow machined in the rib corresponding to the roller of this lever shall have reached a position allowing such motion.
  • the hollows 60, 61 and 62 are of different lengths.
  • the angular length of hollow 60 corresponds to a double pitch of toothing 5, that of hollow 61 to a triple pitch and that of hollow 62 to a four-fold pitch.
  • the commutation finger-piece 4 again engages toothing 5 and cuases the date ring to advance, so that the end of hollow 61 will again lift roller 49 and disengage date-setting member 43 from the date-ring.
  • the user of the watch must activate stem 56 so as to rotate the control member 35. in the clockwise sense as shown in FIG. 3; this will bring the peg of springpawl 59 into the front end of notch 60.
  • finger-piece 42a Approximately 2% hours after this commutation, finger-piece 42a will again come and activate the date ring and will immediately cause date 1" to appear in the window.
  • plate 35 may be provided with index marks appearing in a secondary window which corresponds to window 32 and allowing the user to know at any time how the correction mechanism is programmed.
  • index marks may consist in showing the four dates of 28, 2 9, 30 and 31 as borne on plate 35 and shown in FIGS. 4 and 6; one of those dates appears in the secondary window, which, in this instance, is located at 12 0clock according to the position of plate 35.
  • one may also provide other symbols to theguser, in lieu of the four mentioned dates for the desired indication.
  • FIGS. 4 through 6 represents an array quite analogous to that of FIG. 1 and particularly, its height requirement is of the same order.
  • date-ring 2 is fastened to bottom plate 1 in the same manner as in the other embodiments, and its toothing 5 functions in concert with commutation member 3 which is provided with a rigid finger-piece 4 and pivots about a fixed peg; screw 11 is atthe center of this peg; the screw shoulder guides control plate 63 which is also guided by the shoulder of screw 13 and may rotate to the extent of the two positions defined by the ends of slots 14 and 15.
  • This embodiment therefore is similar to the first one as regards the possibilities it offers, since it allows only programming automatic commutation from the date 30" to the first of the next month.
  • plate 63 The alternate displacements of plate 63 are controlled by a star 18 identical with the one shown in FIG. 1; this star is ganged to a six-tooth ratchet wheel activated by push-piece 20.
  • Pin 19 will take a position either at the end of one of the arms of star 18, or in the hollow between two of those arms; under the influence of spring 16 pushing against pin 17, plate 63 rotates counter-clockwise before it is brought back by spring 16 to the position shown in solid lines in FIG. after a new pressure has beenapplied to push-piece 20.
  • the commuting member 3 also is driven by the intermediary of setting wheel 6 and wheel-and-pinion 7; the latter itself is driven by hour-wheel 8 and thus causes a reduction in the ratio of 2 to 1, so that the commuting member rotates at one revolution every 24 hours.
  • a variation provides for a different way of driving this commuting organ: particularly, the toothing might have a diameter twice that of a wheel directly fastened upon the hour-wheel and the toothing might directly mesh in with such wheel.
  • the commuting member 3 might also be provided with a device ensuring immediate jumping of date member 2.
  • the mechanism shown in FIG. 7 comprises a lever 64 pivoting at one of its ends around a peg co-axial with screw 13; a pin 65 is fastened to the other end of lever 64, and this pin may function in concert with a date-setting tooth 66 ganged to date ring 2 and located below the normal toothing 5
  • this tooth will be fastened by screwing or by driving in or by soldering and it will be the only inward projecting element along the entire periphery of date ring 2, at the level of which it is located (FIG. 8).
  • lever 64 bears a pin 67 engaging an elongated opening from a cam 68 which is mounted in pivotable fashion upon a peg ganged to the bottom-plate.
  • This cam is provided with a lug itself provided with radial flank under the influence of a spring 69.
  • This cam also supports a pivoting finger-piece 70 which is being pulled by a spring 71 and located at the level of toothing 5 and very near it.
  • pawl 70 When cam 68 rotates clockwise round its axis, pawl 70 may pull out of the way by gliding on the teeth of toothing 5; but when the cam rotates counter-clockwise, the pawl front end can grip a tooth of toothing 5 and cause ring 2 to advance sufficiently for jumper 28 to jump above the top of a tooth; then jumper 28 ensures the advance of the date member by an amount corresponding to one pitch of its toothing.
  • tooth 66 drives lever 64 and cam 68 against spring action of spring 69.
  • Pin 65 describes an arcuate path centered upon the axis of screw 13, deviating towards the inside of toothing 5; in that manner pin 65 passes above tooth 65 before the date ring has reached its new position corresponding to the date 31.”
  • the cam pivots round its axis and in the clockwise sense so as to cause pawl 70 to pass above one of the teeth 5; it is then released and spring 69 will then bring back cam 68 and lever 64 to their initial positions shown in solid lines in the drawing.
  • pawl 70 causes a new commutation during this motion; this commutation is instantaneous and affects the datemember, so that the number 1 appears in the window.
  • Both plates 63 and 12 bear date indications 30 and 31; these may appear in an auxiliary window located at 12 oclock and constantly indicating to the user how the watch is programmed. In such a case too, the indications 30 and 31 the principle of its mechanism might also be applied to an automatic commuting mechanism from the 29th to the lst or from the 30th to the lst, according to the control member position.
