Definitions

  • a watch includes a dial train drive in which power is transmitted from an oscillating balance wheel to a magnetizable index wheel.
  • the index wheel drives the gear train of the watch.
  • the balance wheel oscillates a lever between two end positions and a pin on the lever steps the index wheel.
  • a magnet positioned adjacent the index wheel holds the lever in its rest position.
  • the present invention relates to watches and more particularly to a dial train drive.
  • the dial train is driven by an oscillating lever which is driven by an impulsed and oscillating timing balance wheel.
  • This lever has driving means which rotate an index wheel, so that at each oscillation of the balance wheel the index wheel is stepped up a pre-set step.
  • the step is equal to half the circular pitch of the index wheel.
  • the lever and the index wheel be kept in their final step position.
  • the lever and the index wheel are locked in their final step position by a magnet positioned near the lever and a mechanical pawl acting on the index Wheel. A recoil of the index wheel by outer influences, such as external shock, is prevented by this lock.
  • one magnet locks the index wheel and another magnet locks the lever.
  • the objective of this invention in this type of power take-off, is to simplify the lock means for the index wheel and for the lever, so that the drive is relatively reliable, inexpensive and small.
  • a magnet is provided for each step of circular pitch of the index wheel so that a direct or indirect magnetic influence locks the lever as well as the index wheel.
  • the use of a single magnet to perform both functions results in a simpler mechanism and conserves space, which is especially important in wrist watches.
  • Embodiments of the present invention are that the lever as well as the index wheel are directly locked or only the lever or only the index wheel is directly locked. In another embodiment only the lever or the index wheel is locked and a force is exerted by the magnet on the wheel in the case of the lever and 70 the lever in the case of the wheel, whereby the other part will also be locked.
  • step is equal to one circular pitch of the index wheel, only one magnet is necessary.
  • the arrangement may be that several steps, especially two steps, constitute one circular pitch and in this case the number of effective magnet poles corresponds to the number of steps.
  • FIG. 1 is a top plan view of a schematic representation of the first embodiment of the invention
  • FIG. 2 is a partially cross-sectioned side view taken along lines 11 of FIG. 1;
  • FIG. 3 is a top plan view of a schematic representation of a second embodiment of the present invention.
  • FIG. 4 is a top plan view of a schematic representation of a third embodiment of the present invention.
  • FIG. 5 is a partially cross-sectioned side view of a fourth embodiment of the present invention.
  • FIG. 6 is a top plan view of the embodiment of FIG. 5 with the lever in its second step position;
  • FIG. '7 is a top plan view of the embodiment of FIG. 5 with the lever in an intermediate position between its final positions;
  • FIG. 8 is a top plan view of the embodiment of FIG. 5 with the parts in the first step position.
  • the dial train drive shown in FIGS. 1 and 2 includes driving portion of the balance wheel 10 comprising the balance staff 11 and an impulse disk 13 provided with an impulse jewel 12.
  • the impulsed balance wheel (not shown) and the disk 13 are rigidly fixed on staff 11.
  • the staff 11 is carried in bearings in the frame of the watch (not shown).
  • the disk 13 cooperates with a lever having a horn arm 23 with its horns 21 and 22 and having a fork arm 27 with fork spokes and 26.
  • the horns 21 and 22 form a slot 28a which cooperates with the impulse jewel 12.
  • Magnetic pieces 30 and 31, of magnetizable material, are integral with the ends of spokes 25 and 26, respectively.
  • An index wheel arbor 38 having integral pivot ends 36 and 37, is carried in bearings in the plates 40 and 41 (the plates being shown broken away).
  • Arbor 38 is rigidly fixed on a corresponding shoulder of a reinforced center part of the index wheel 35, see FIG. 2.
  • a bearing bushing 44 is provided for the bearing of the lever 20, on whose circumference the lever 20 is rigidly fixed.
  • the bearing bushing 44 is rotationally arranged over a part of the bearing staff end 37 and over a bearing pivot 45 of the index wheel arbor 38.
  • the bearing bushing 44 is axially held between plate 41 and the front face of the index wheel arbor 38.
  • the lever 20 oscillates independently from the index wheel in a plane parallel to the plane of the index wheel.
  • the oscillation motion of the lever 20 is limited by a limitation finger 46 which is fixed on a stationary part of the watch.
  • this limitation finger 46 is arranged above a permanent magnet 50 (partially shown) whose pole 51 cooperates with the teeth of the index wheel and the magnetic pieces 30 and 31.
  • Magnet 50 can be used so that its locking action is caused by its single pole. In order to improve the magnetic flux, both the magnets poles may be used for locking.
  • the pole is located in respect to the iron parts of the lever and of the index wheel so that the magnetic resistance is minimum in the lock position.
  • at least the teeth of the index wheel are made of magnetizable material, but preferably the whole index wheel is made of such material.
  • the pole 51 of the magnet 50 has a toothlike shape on its front end 52 so that the small front face 53 is at times opposite to the index wheel tooth.
  • FIGS. 1 and 2 works as follows:
  • the front face 53 of the magnet is opposite an index wheel tooth 35a of the index wheel 35 so that the tooth is retained in this position by the magnet.
  • the magnetic piece 30 is attracted by the pole 51 and is pressed against the limitation finger 46.
  • the orientation of the lever 20 is that shown in FIGS. 1 and 2 and the position of the index wheel 35 is determined by the single magnet 50.
  • Spring 28 pushes the index wheel 35 an amount corresponding to the swing of the lever.
  • the tooth 35a is rotated out of the effective range of the magnet 50 and the next tooth 35b enters this effective range, so that tooth 35b takes the same position near the pole 51 as the tooth 35a had previously.
  • the return swing of disk 13, opposite in direction to arrow A restores the lever to the same orientation as in FIGS. 1 and 2 so that the power take-off is ready for the operation to be repeated.
  • impulse jewel 12 can move into the slot 28a and also strike the index wheel directly to step up the teeth in one direction, so that the index spring 28a is unnecessary.
  • the step is equal to the circular pitch of the index wheel and a single magnet is necessary.
  • the magnet 50' cooperates with one tooth of the index wheel and subsequently with one of the magnetic parts of the lever.
  • the magnet 50 exerts its locking without any contact with a tooth of the index wheel or the lever, so that sticking is prevented by the air gap between the magnet and parts attracted by it.
  • a non-magnetic layer may be placed on the concerned parts or on the magnet.
  • the disk is desig mated with the same reference figures as in FIGS. 1 and 2.
  • the lever 60 has a horn arm 61 with horns 62 and 63 forming between them a slot 64 and a pin arm 65 on which spokes 66 and 67 are arranged.
  • Lever pins 68 and 69 and magnets 70 and 71 are, in the vicinity of the pins, fixed on spokes 66 and 67, respectively.
  • the lever 60 is fixed on the staff 72 which has its bearing in the frames (not shown).
  • the oscillation of the lever in the counter clockwise direction is limited by a banking pin 73 fixed to a frame.
  • the index wheel 75 is fixed on an index wheel arbor 76 which has its bearing in the frames (not shown).
  • the lever 60 lies against the banking pin 73 and is retained in this position because the magnet 70 is attracted to the tooth 75a, the attraction of the magnet being toward axis 76.
  • the entire index wheel 75, or preferably its teeth, is made of magnetizable material.
  • the index wheel is shifted half a circular pitch at each lever oscillation.
  • a single magnet locks the lever and the index wheel at each step.
  • the magnets are here arranged on the oscillating lever and cooperate in the lock position with one tooth of the wheel.
  • the lever stops the index wheel at each step for half a circular pitch then two magnetic poles on the lever are necessary, the poles being arranged in an appropriate distance from each other.
  • the poles can be the poles of a single magnet or the poles of separate magnets.
  • the disk is again designated with the same reference figure as in the preceding forms.
  • the lever 80 has a pin arm 86 having a first spoke 87 and a second spoke 90.
  • the lever pins 88 and 91 are arranged on spokes 87 and 90, respectively.
  • the lever 80 has also a third spoke 93 which forms together with the second spoke a limiting fork which cooperates with the banking pin 94.
  • the lever is fixed on a lever staff 96 which has its bearing in the frame (not shown).
  • each tooth of an index wheel has a draw face 98.
  • the index wheel is fixed on an index wheel staff 100 which has its bearing in the frame (not shown).
  • Two magnets 102 and 104 cooperate with the index wheel teeth. These magnets can be formed similar to the magnet 50 of FIGS. 1 and 2.
  • the magnets 102 and 104 have poles 105 and 106 and teeth 107 and 108, respectively. Tooth 107 has a front face and tooth 108 has a front face 111, respectively.
  • the magnet 104 tries to rotate the index wheel 97 in the direction of the arrow E.
  • the draw face 98 of the tooth 97s presses against the lever pin 88 so that the spoke 90 of the lever 80 is pressed against the banking pin 94 and a new stable position is created by the influence of the single magnet 102.
  • the lock occurs in this embodiment because a stationary magnet which cooperates with the index wheel is provided for each step.
  • the lever is pressed and locked on the banking pin by the draw of an index wheel tooth on a lever pin.
  • the orientation of the lever and the index wheel is such that the stationary magnet, by its attraction on the nearby tooth, tries to move the tooth forward and locks the wheel.
  • the lock position of the lever is also determined by the same lock on the index wheel.
  • balance staff 120 is retained in conventional bearings.
  • a balance wheel impulse disk 122 has mounted on it a roller jewel 123 which in turn engage fork 127 of the lever 126.
  • the lever is mounted on lever staff 130 which has its bearing in the upper plate 132 and the lower plate 133.
  • indexing jewel 135 is mounted on the lower side of the lever 126 which jewel engages index wheel 144.
  • Index wheel 144 and index wheel pinion 142 are fixed on the index wheel staff 144.
  • the index wheel staff 144 has pivots 146 and 147 which are mounted on frame plate 132 and 133, respectively.
  • a banking pin 150 made of a magnetizable material such as iron, is mounted on lever 126.
  • the banking pin cooperates with two banking faces 152 and 154 of the upper frame plate 132.
  • a magnet 160 is fixed to the lower frame plate 135 and is formed with a truncated cone shape 161 at its upper end.
  • a tooth 165 of the index wheel is located above magnet 160 and symmetrically above the truncated cone end 161 in such a manner that tooth 165 is locked in position.
  • the banking pin 150 by means of magnet 160, is attracted and pressed against the banking face 154 of the upper frame plate 132 so that both the index wheel 140 and the lever 126 are locked.
  • the banking pin 150 engages between two teeth of the index wheel 140 and prevents rotation of the index wheel while the wheel is in its rest position.
  • FIG. 7 shows the position between both rest positions wherein the banking pin 150 has not yet reached the banking face 152 of the upper frame plate 132.
  • tooth 168 cannot reach a symmetrical position relative to magnet 160 and this therefore means that a consistent draw in the circumferential direction on tooth 168 will be exerted by magnet 160.
  • Tooth 166 will continue to be pressed against the indexing jewel 135 and the banking pin 150 will continue to be pressed against banking face 152.
  • Tooth 166 is located essentially tangential to index jewel 135 so that practically the full moment of the magnet on the tooth 168 will be transmitted to the lever 126.
  • the jewels holding action described above ceases and the magnet 160 is supposed to swing the index wheel by the short remaining distance to the FIGURE 6 position in which tooth 165 (168 in FIG. 8) is symmetrically located over the cone end 161 of magnet 160, as described above.
  • the magnet serves this purpose, the resulting homing-in of the index wheel occurs even if, as in some prior index systems, the jewel 135 has caused a slight reverse motion of that wheel incident to the retreat of the jewel to the left from the space between index teeth 166 and 167.
  • the system disclosed has a desirable further action, evident from FIGURES 6-8, in the event that a drag develops, such as often happens, as a result of an accumulation of friction producing conditions opposing the motion of the index wheel 140.
  • a drag develops, such as often happens, as a result of an accumulation of friction producing conditions opposing the motion of the index wheel 140.
  • the indexing lever 126 and index wheel 140 do not quite reach the final position shown in FIGURE 8, but halt at a position short of that, as represented in FIG. 7, at the end of the positive clockwise drive of the index wheel 140 by the jewel 135.
  • the desired locking effect of the single magnet 160 is still present in that event of drag because the banking pin still is held by magnetic attraction against the stop 154 as shown in FIGURE 6, and this holds the lever 126 in the position shown.
  • the pin 150 has an inherent fail-safe role inassuring a proper positioning of the index wheel on the idle stroke of the jewel 135, even if drag prevents the homing action of the magnet, from bringing the wheel to its desired rest position; positioning of the index wheel in either event being such that on the next succeeding half oscillation toward the first position the driving jewel 135 assuredly enters the space between index teeth 166 and 167 to exert the advancing action depicted (at its termination) in FIGURE 7.
  • a dial train driving mechanism including an oscillatory timing wheel rotatably secured to the plate and having driving means, means to impulse the timing wheel so that it oscillates, a lever having driving means rotatably secured to the plate and oscillated by the timing wheels driving means, an index wheel rotatably secured to the plate having magnetizable teeth with draw faces, said wheel being driven by the levers driving means, a magnet adjacent the teeth of the index wheel, and fixed means to bank the lever, wherein the lever driving means and the index wheel teeth having a draw face contact so that in one of its locking positions the magnets field holds a tooth and the said draw face locks the lever.
  • levers driving means consist of two pins protruding from the lever
  • the said second pin being arranged also to enter the space between two adjoining teeth of said index wheel when the said index pin is swung away from said index wheel,
  • a second banking pin carried by said lever at a point on the opposite side of its pivot from the said index pin but not arranged to advance the index wheel similarly, said second pin arranged to be swung by said lever between said banking stops, the said second pin being arranged also to enter the space between two adjoining teeth of said index wheel when the said index pin is swung away from said index wheel, and a magnet having a pole face closely adjacent to the circle of teeth of said index wheel at a point on said circle at which it also is closely adjacent to the terminal position of said second pin at which the said second pin is between two teeth of said index wheel, the said magnet as thus positioned tending to move said index wheel to a rest position and to hold it there by its magnetic action on an approaching tooth of said index wheel at the end of a driving stroke of said index pin, and tending also by magnetic action to hold said second pin in its said terminal position between two teeth, and the arc of swing of said second pin toward
