Definitions

  • the invention relates to a perpetual calendar mechanism for a timepiece comprising a month star performing one revolution per year, a month cam fixed on the month star and having solid parts corresponding to the months of thirty-one. days, shallow notches corresponding to those of thirty days and an opening located between the solid parts corresponding to the months of January and March, a mobile pivoting on the star of the months and comprising inter alia a cam of the years arranged to perform a in four years, said year cam having four flanks appearing in turn in said opening, a month indicator and a four year cycle indicator.
  • the star of the months is provided with a mobile which pivots on it and which comprises a cam of the years which is arranged to carry out a turn in four years.
  • the present invention precisely takes advantage of this arrangement and causes the indication of the cycle of four years to depend, not on the rotation of the star of the months but on the position of the cam of the years, which leads to a simplified construction and less cumbersome.
  • the date display (not shown in the drawings which accompany this description) can be done by means of a hand or even by means of a disc, the numerical indications of which appear in turn through a window.
  • the needle or the disc capable of making a turn in thirty-one days, is controlled by a so-called multiple rocker of which one of the spouts is controlled by a cam which makes a turn in twelve months and which will be discussed below.
  • Fig. 1 is a top view of a first alternative embodiment of the invention.
  • the indications 2 relating to the months of the year and distributed over a circumference.
  • the month 3 needle is chased on a month 4 star cannon which pivots on a post 5.
  • fig. 2 is a section through FIG. 1, we see that the post 5 is secured to the calendar board 40 for example by hunting.
  • the star 6 On the barrel 4 is driven the star 6 which thus rotates freely around the tenon 5 which serves as its pivot axis.
  • a month cam 7 is fixed on the star by means of screws 8.
  • the spout of the multiple rocker rests to slave the date hand to the current month as was mentioned above.
  • the beak of the rocker is symbolized in figs. 1 and 2 by arrow 14 while the servo mechanism of the date indicator is not shown.
  • the month star 6 carries twelve teeth and the cam 7 has solid parts 9 corresponding to the months of thirty-one days and shallow notches 10 corresponding to those of thirty days.
  • the cam 7 In the cam 7 is made an opening 11 situated between the solid parts corresponding to the months of January 9 'and March 9 ".
  • this opening 11 In this opening 11 is housed the cam from the 12s which is presented as a small rectangle forming part of a mobile 13 pivoting on the star 6. It is apparent that three sides of the rectangle are equidistant from the pivot point 15 while the fourth, which is here in the form of an arc, is further away.
  • the spout 14 In February, the spout 14 is opposite the opening 11. If, at this moment, is turned towards the outside of the opening 11. If at this moment, is turned towards the outside of the opening 11 one of the three flanks closest to the center, the beak 14 will have its maximum penetration, which will correspond to a month of February of twenty-eight days.
  • the cam 12 makes one revolution in four years, which generally is obtained in the following manner.
  • the cam 12 is provided with a barrel 16 cut in a square which pivots freely in the star 6.
  • a Maltese cross 17 with four entrances held integral with the cam of the 12 years by a screw 18.
  • a finger from the 26s is chased on the tenon 5.
  • the finger 26 therefore remains stationary.
  • the star 6 makes one turn per year, it will be understood that the Maltese cross 17 and therefore the cam of the 12 years which is linked to it will only turn a quarter of a turn during the same period of time.
  • the arcuate side of the cam 12 will be placed in front of the opening 11, as shown in fig.1.
  • the present invention takes advantage of the state of the art which has just been exposed to control a four-year cycle indicator by the mobile 13 pivoting on the star and of which the cam of the 12 years.
  • the mechanism first has a first ring 20 which is integral with the month star 6. It can be seen that the screws 8 are screwed into a thread formed in the ring 20 in such a way that when they are tightened, ring 20, cam 7 and star 6 form a rigid assembly which performs one revolution per year and which drives in its rotation the month needle 3, said needle being integral with the barrel 4 itself integral with the star 6.
  • the mechanism then has a second ring 21 arranged to rotate freely inside the first ring 20.
  • This second ring is driven on a pinion 22 mounted freely on the barrel 4.
  • the teeth 23 of the pinion 22 mesh with a toothing 24 carried by the mobile 13 pivoting on the star 6.
  • the second ring constitutes the cycle indicator of four years proper and happens to be controlled by the mobile 13.
  • the finger 26 begins to enter an entry 27 of the Maltese cross 17.
  • the mobile 13 is then rotated in the direction of the arrow 28 if the star rotates in the direction of the arrow 29.
  • the Maltese cross occupies the position illustrated in fig. 3.
  • the entry 27 of the Maltese cross 17 will leave the finger 26 and in February the round 50 of the Maltese cross is again in contact with the circular part 25 of the finger 26.
  • the Maltese cross 17 and the mobile 3 which is linked to it will have made a quarter turn in the direction of the arrow 28 and will have driven, via the toothing 24, the pinion 22 and the second ring 21 by a quarter turn In the opposite way.
  • the visible faces of the rings 20 and 21 are arranged in the same plane as the visible face of the dial 1.
  • the visible face of the first ring 20 is divided into four areas, the first marked "1", the second marked "2", the third marked “3” and the fourth marked "leap”.
  • An index 30 is affixed to the visible face of the second ring 21. From February to September, the month hand 3, the first ring 20 and the second ring 21 rotate in synchronism in the direction of the arrow 41 The index 30 remains permanently centered in front of the range marked "leap" of the first ring 20, thereby indicating that the current year is a leap year.
  • the second ring 21 begins to rotate in the opposite direction to the first ring 20 and in the direction of the arrow 31.
  • the index 30 will be centered on the indication "1" indicating a first pre-leap year.
  • the hand 3 could be replaced by an index affixed to the first ring 20, said index then playing the role of indicator of the months.
  • the cam from the 12s is surmounted by an indicator disc from the 36s which is chased there and therefore rotates with it.
  • the ring 35 is provided with a window 37 which reveals information carried by the disc.
  • the disc 36 will make a revolution in four years and present through the window 37 four different tracks, the change of track taking place over four months (October to January) so that the indication of the current year appears clearly when we approach the month of February.
  • the indicator disc for years 36 turns on itself at each change of year and revolves around tenon 5 in a year driven by the star 6 and the ring 35 secured to said star.
  • Fig. 4 is a top view of the indicator according to this second variant.
  • the visible surface of the ring 35 is at the same level as the top of the dial 1 of the watch.
  • This dial bears the indications 2 of the months.
  • the month indicator here is an index 38 affixed to the ring, but it could be a needle driven out of the barrel 4 (see fig. 5), as was the case in the first variant described above.
  • the disc 36 contains four pieces of information distributed at equal distance from each other, three of which relate to the pre-leap years and marked "1", "2" and "3" and the fourth of which relates to the leap year and marked "BIS". One of this information appears in the window 37 and then changes with each revolution of the index 38.
  • this second variant of embodiment directly takes advantage of the rotation of the mobile 13 pivoting on the star 6 to display the current year since it is no longer necessary to equip the mechanism with a pinion meshing with a toothing as in the first variant.
  • this second variant requires a ring 35 of large diameter so that the indications carried by the disc 36 are still legible in the window. This drawback could be avoided by replacing numbers and letters with colored dots, for example red for the leap year, white, black and blue for the pre-leap years.
  • the disc 36 could be replaced by a needle whose axis would be integral with the mobile 13 and would cross the ring 35.
  • the indications "1", “2" and “3” and “leap "Would be affixed directly to the ring 35.
