Definitions

  • the present invention relates to a watch movement which includes, besides the elements which indicate hours and minutes by means of a permanent drive arrangement, at least two totalizers and a drive and control mechanism therefor whereby they may be connected to the movement so as to be driven by it or they may be disconnected from the movement or returned to a zero position, said totalizers and indicators being coaxial.
  • Watch movements of this kind are already known in which each one of the totalizers has a cog wheel mounted to the center of the movement. These cog wheels are of the same diameter. Each one of these wheels is connected to a barrel of the watch which passes through the central opening of the dial and which has a totalizing hand which moves above the dial opposite the turn of the hours. In these known watches, the totalizers count the minutes and the hours, respectively.
  • the control mechanism is composed of a second pair of cog wheels which are always in contact with one of said cogs and which carry the hearts" for return to zero which are activated by a lever for return to zero.
  • the purpose of the present invention is to create a watch movement of the kind mentioned above which has a control and engaging mechanism which is more simple than those of the movements which have been known up to this time, which has a small number of pieces and is smaller in size, particularly in the center of the movement.
  • the watch movement according to the invention is characterized in that these totalizers contain cogs of different diameter equipped with cores for return to zero each one of which is connected to one of said elements (totalizers), the cog of greatest diameter of the first totalizer being connected to the spring drum by a watch train partially mounted on a lever.
  • FIG. I is a top view of the dial of the movement
  • FIG. 2 is a partial cross-sectional view along the line II-ll of FIG. 3;
  • FIG. 3 is a top view of the movement taken after the dial has been removed and the totalizers taken out;
  • FIG. 4 is a top view taken after the dial has been removed and the movement totalizers have been partially taken out.
  • FIG. 1 shows the appearance of the visible side of the watch.
  • the dial 1 has two long windows 2 and 3 extending in an arc of a circle concentrically to the axis of the hands, 4, 5 and 6.
  • the window 2 extends on both sides of noon immediately inside of the hour indications 7, whereas the window 3, with a smaller opening, extends in the opposite direction, that is to say on both sides of 6 o'clock and in the immediate vicinity of the axis of the hands.
  • the first of the two totalizers 8 and 9, which are visible in these windows and which are described in greater detail in what follows, has a peripheral scale 10 which corresponds to the 60 minutes of the hours and the other one has the figures for the hours, 11, from 1" to 12. Index marks 12 and II!
  • the indicators 8 and 9 turn past the index marks 12 and 13 thus indicating at all times the time which has elapsed. This time is given in hours and in minutes, but it is quite obvious that in other forms of design one could also give this indication in minutes and seconds.
  • the indicator 9 has numbers from I to l2 and is controlled in such a way as to carry out a revolution in l2 hours when the mechanism is engaged it is quite clear that one could also have an element for indicating hours which makes a revolution in 24 hours and which has numbers from I to 24.
  • the totalizer of the hours and of the minutes have a dragging movement, that is to say that as soon as they are engaged they turn continuously.
  • one or the other of these indicators totalizers) and more particularly the hour totalizer could also be activated by jumps. The changes which would have to be made in the mechanism to achieve this jump drive will be indicated further on.
  • the watch which is shown in the drawing does not include an indicator for the days of the month.
  • the total izer mechanism could also, if necessary, be built into a calendar watch.
  • the dial could be equipped with a window for the date of the month situated for example at the site of one of the hour indications.
  • the clutch l9 carries a wheel 20 of the same diameter and of the same modulus as the hour wheel 17. These two wheels are positioned immediately one above the other.
  • the foil 2! which is secured by the elastic ring 22 presses the assembly of the disc 9, of the clutch I9 and of the wheel 20 against the hour wheel avoiding any axial contact. Since the lower extremity of the clutch 19 extends slightly protruding with respect to the wheel 20, the latter is slightly separated from the hour wheel thus preventing any rubbing between these two elements.
  • the clutch I9 is made in a single piece with a flat side part 23 which extends above the wheel 20 and which has the shape of a heart, as is shown in F IG. 3. This heart permits the return to zero of the totalizer 9, as will be seen further on.
  • the clutch 19 has a cylindrical extent upon which is mounted an element 24 the outside shape of which is of exactly the same dimensions and the same shape as the element 23 and which has around its central opening an annular ribbing onto which the disc 8 is driven which constitutes the minutes totalizer. At its lower edge the heart 24 also has a ribbing which provides for the presence of a slight play between the two hearts.
  • the adjustment of the central opening of the heart 24 on the central area of the clutch 19 is also a free adjustment so that the indicator disc 8 can turn independently of the indicator disc 9.
  • the disc 8 extends therefore in its central part under the disc 9 but it presents, according to a circle having the diameter of this disc, a sheathing which brings its peripheral part to the same height as the element 9, that is to say directly below the dial.
  • the peripheral part of the disc 8 which has the minute indications 10 appears immediately below the opening of the window 2.
  • the cogged rim rests on a circular ribbing 26 located in the upper part of the cover plate 277 This element is therefore supported at its periphery but can still turn about its axis.
  • the activating of the disc indicating the minutes 8 is done by the periphery of the movement.
  • the movement has an additional moving drive part 28 the pinion of which is in direct contact with the ribbing of the cylinder drum 29.
  • This additional moving body pivots between the plate and a bridge 30 which can be, for example, the cylinder bridge.
  • the moving body 28 has at one extremity of its shaft a wheel 31 which is housed in a hollow place inside of the cover plate and which, for activating the disc 8, is put into contact with the wheel of a transmission moving body 32 having a pinion and a wheel and mounted on a lever 33.
  • a simple return 34 is used, in the form of design described, for activating the hours totalizer 9, that is to say the clutch l9 and consequently the wheel 20.
  • This return is shown in FIG. 2 with broken lines.
  • This return (gear) which is held by a lever 35 is of a height such that it can simultaneously come into contact with the wheel 17 and the wheel 20. In order to bring about the activation of the element 9 it suffices therefore to move the lever 35 in order to bring the return 34 into contact with the two cogs which are to be connected. This return simply brings about a coupling between the wheels 17 and 20.
  • the hours totalizer it is only necessary to replace the return 34 by an intermittent drive mechanism and replace the wheel 20 by a star with 12 or 24 cogs.
  • the intermittent drive mechanism would then be mounted on the lever 35 and could include the necessary elements to gradually accumlate, for example, in a spring, the power which is necessary to make the element 9 jump by one step and to release this power at the desired instant in order to make the star of the totalizer advance by an angle corresponding to l hour.
  • the levers 33 and 35, as well as the moving body 32 and the return 34, are also visible in FIG. 3 where they are represented by solid lines in the engaged position.
  • the rim 25 is shown by broken lines and we can see that the cogs of the pinion of the moving body 32 is in contact with it whereas the cog of the wheel of this moving body is in contact with the wheel 31 of the additional moving body 28.
  • the lever 33 pivots on a stud 36 which is secured in the plate. [ts extremity opposite the moving body 32 is pulled by a spring 37 which continuously tends to separate the lever from the rim 25.
  • the described watch movement has a control lever 38 which is held against the inside of the coverplate by a lug 39 driven into that piece.
  • This lever 38 has three arms 38a, 38b and 380. It is cut with a small tongue 40 which is folded up in a right angle and which is located in the vicinity of the lug 39 at the periphery of the movement so as to be opposite the side of the case.
  • the latter is equipped with a pusher making it possible to push on the small tongue 40 in the direction of the arrow A (FIG. 3) and then making the lever 38 pivot in the hour direction starting from the position shown by solid lines.
  • the arm 38a of the lever extends opposite a lug which is located at the end of the lever 33 beyond the pinion 32.
  • the arm 38c constitutes a hammer the edge of which has a greater thickness than the central part.
  • the cam 43 has two notches 42a and 42 b at its periphery.
  • the hammer 38c carries out the movement mentioned previously, during the stopping and return to zero of the totalizer mechanism its extremity passes into the notch 42a and rests against the side of this notch causing the cam to rotate to the position represented by broken lines in FIG. 3.
  • the rear side of the notch 42! moves the cam following stud 35d on arm 35a and consequently causes the lever 35 to pivot in the hour direction against the action of the spring 45, thus separating the return 34 from the cogs of the wheels 17 and 20.
  • the elements described above assure the stopping of the totalizer and its return to zero by a single movement of the lever 38 under the action of the pusher working in conjunction with this lever.
  • the position represented by the broken lines in FIG. 3 is therefore the normal position when the totalizer is not being used. The pusher is then pushed inside.
  • the pusher can be provided in such a way that it can be moved towards the outside.
  • This pusher will work together in conjunction with a spring mechanism which assures these two positions.
  • the lever 38 is released which, under the action of its spring 4] which is stronger than the spring 37, shifts the lever 38 and the scale levers 33 and 35.
  • the lever 33 is driven against the action of the spring 37 and in the hour direction, carrying out the engaging of the minutes totalizer element. Pivoting of the lever 38 under the effect of the spring 41 separates the hammer from the hearts 23 and 24.
  • the extremity of the hammer catches the edge of the notch 42a of the cam 42 and makes it pivot in the hour direction so that the lug 35d can enter the notch 42b which brings the lever 35 into its position as shown by broken lines.
  • the engaging and disengaging positions are therefore controlled by the same pusher.
  • the two extreme positions of the lever 35 are determined by the stud 46 which moves into the opening 47 provided in the plate and the positions of the lever 33 are determined by the stud 56 situated at its extremity opposite the moving body 32 and by the opening 57 (H6. 4).
  • the mechanism shown in FIG. 3 also has the lever 48 which pivots on the stud 49 and which extends along the periphery of the movement at a level which is slightly lower than that ol' the hammer 38.
  • This lever has a lowered small tongue 50 which is situated, as the small tongue 40, at the periphery of the movement and at its extremity opposite the pivot 49 there is a stud 51 which extends on the side of the arm 38: of the lever 38.
  • the movement which is equipped with the lever 48 has the advantage that the control pusher can be placed at will along side 4 o'clock or alongside 8 o'clock with respect to the stem winder oriented at 3 o'clock. It is therefore possible to vary the presentation of the watch.
  • the action of the pusher in the last case causes the pivoting of the lever 48 in the counterclockwise (anti-hour) direction so that the lever 38 is engaged and the other elements of the mechanism follow the movement of the lever 38 as has been described.
  • FIG. 4 shows another possible variation for the engaging and disengaging mechanism.
  • This mechanism is controlled by the stem winder which makes possible the two engaging and disengaging movements of the totalizer mechanism.
  • the lever scale 33 and the lever 38, as well as the lever scale 35 and the cam 42, which were not represented, are arranged as in FIG. 3.
  • the lever 48 is eliminated and the case does not have any pusher.
  • the stem winder which works together with the drawer 52, is activated so that it can be brought into a third position by pressure exerted on the rim from the winding up position.
  • the drawer spring can have a third notch providing this third position.
  • an arm 53 is provided between the lever scale 33, the lever 38 and the drawer 52, said arm pivoting at one of its extremities, for example, about a screw 54 (FIG. 4).
  • This arm passes in front of the drawer plug 52a between the stud 55 secured approximately at the middle of the arm 38b of the lever 38 and the small tongue 40.
  • the other elements of this mechanism are similar to those which are shown in FIG. 3.
  • the lever 38 pivots in the clockwise direction bringing the hearts to zero and engaging the totalizers.
  • a reverse movement imparted to the stem causes a shift of the drawer and a pivoting of the lever 38 in the counter clockwise direction under the action of the spring 41 which, also in this case, must be stronger than the spring 37.
  • a watch movement having means for continuously indicating two different units of measure of time, said movement additionally comprising,
  • a cylinder drum associated with means for driving said watch movement, said cog of greater diameter adapted to be operatively engaged with said cylinder drum through a watch train, a portion of which is mounted on a first lever arm.
