Definitions

  • a hand-setting device to set the hands of a watch in which a setting crown on the outside of the case is coupled with a gear by a setting stem.
  • the gear meshes with a second gear and this second gear meshes with the dial train to set the hands.
  • This known construction has the disadvantage that it requires a relatively large space.
  • separate bearings for the setting stem are provided so that the watch is correspondingly more expensive.
  • a watch having a crown exterior to the case for setting the hands.
  • the crown is capable of being coupled to a setting stem when it is pulled outward from the case.
  • the setting stem carries a gear which is in constant mesh with a gear arranged on the center wheel staff. Another gear on the setting stem is in constant mesh with the hour 7 wheel.
  • the first gear fixed on the setting stem is the minute wheel-i.e. the wheel between the wheel carrying the minute hand and the wheel carrying the hour hand.
  • the transmission ratio is chosen so that the adjustment of the minute hand can be accurate.
  • the cannon pinion center wheel having a similar number of teeth, preferably an equal number of teeth.
  • FIG. 1 is a side view, taken in cross-section along line 11 of FIG. 2, of the hand-setting device of the present invention in uncoupled condition;
  • FIG. 2 is a top sectional view along line 22 of FIG. 1;
  • FIG. 3 is a partial sectional view along line 33 of FIG. 1;
  • FIG. 4 is a partial sectional view along line 4-4 of FIG. 3;
  • FIG. 5 is a view similar to that of FIG. 1 of a portion of the device shown in FIG. 1, but with the hand-setting device in coupled condition;
  • FIG. 6 is a cross-sectional view of another embodiment of the present invention.
  • the fourth wheel is driven by any driving means, preferably by an electric drive.
  • a suitable driving 3,303,641 Patented Feb. 14, 1967 means is described in US. Patent No. 3,046,460 to Ewald Zemla, Pforzheim, West Germany.
  • the seconds hand (not shown) is attached to staff 19.
  • Staff 19 is pivoted in bearing 20 of a bridge 22. The second hearing of this staff will be described later in more detal.
  • a fourth pinion 18 is fixed on the fourth wheel staff 19.
  • Pinion 18 engages a third wheel 12 which is fixed on thrid wheel staff 11.
  • the third wheel staff 11 pivots in bearing 13 in bridge 22 and in bearing 14 in a frame plate 10.
  • a third pinion 15 is turnably arranged on staff 11 so that it is free to rotate on the staff.
  • Pinion 15 presses a spring blade 16 which rests between pinion 15 and the third wheel 12.
  • Pinion 15 is pressed downwards against a positioning ring 17 fixed on the third wheel staff 11.
  • This arrangement acts as a friction coupling so that, by application of a predetermined force, the third wheel staff 11 can be turned relative to the third wheel pinion 15.
  • the third wheel pinion 15 engages a center wheel 28 which is fixed on a center tube 21. Tube 21 turns within bearing tube 24 fixed in the frame plate 10.
  • the second bearing 26 of the fourth wheel staff 19 is within center tube 21.
  • the minute wheel 30 is turnably arranged on a multipurpose staff 32 and it engages the center wheel 28.
  • a minute pinion 34 fixed on staff 32, engages an hour wheel 35.
  • Hour wheel 35 and hour tube 36 are turnably arranged on the bearing tube 24 and an hour hand (not shown) is fixed on tube 36.
  • Staff 32 is pivoted in bearing 37 in the frame plate 10 and in bearing 38 in the bridge 22.
  • the shoulder and reinforcing portion 40 of staff 32 determines the staffs axial position between the frame plate 10 and the bridge 22.
  • Watch case 44 has an opening in which ring 45 is fixed, in which a setting crown 46 can be shifted forwards and backwards.
  • Setting crown 46 has a knurled ring 47 and a shaft 48 which is positioned within the retainer ring 45 by means of a gasket 50.
  • a lock spring carrier 52 is arranged on the inner key of the retainer ring 45.
  • a lock spring 54 in carrier 52 cooperates with an outer lock recess 56 in the pressed-in condition of the setting crown and cooperates with the lock recess 57 in the pulled-out condition of the setting crown.
  • Two follower fingers 51 are arranged on the lower end of the shaft 48 which engage with the recesses 58 and 59 of a coupling disc 60.
  • a coupling spring 62 presses against coupling disc 60.
  • Spring 62 has a ring-shaped pressure part 63 and a spring arm 64 which is fixed with a screw 65 on the bridge 22 (see especially FIGS. 3 and 4).
  • the cou pling disc 60 has two notches 67 and 67a and two bentoff tongs 6'8 and 68;: which with their front end engage under the pressure part 63 (see FIG. 3).
  • the multi-purpose staff 32 has a staff neck portion 70 having a relatively small diameter.
  • the coupling spring 62 and coupling disc 60 have a square hole 72 which corresponds in its form with the coupling square 42 of staff 32.
  • the lock spring 54 disengages from the outer lock recess 56 and engages in the inner lock recess 57.
  • the coupling disc 60 follows the setting crown in its upward movement under the influence of the coupling spring 62 so that the follower fingers 51 and 55 stay in the recesses 58 and 59.
  • the coupling disc slides over the coupling square 42. Since the opening 72 of the coupling disc corresponds with this Coupling square, a coupled condition is now created between the coupling square and the coupling disc.
  • the follower fingers 51 and 55 are coupled with the shaft 48 of the setting crown. Consequently, by rotating the setting crown 46, the staff 32 and also the minute wheel 30 will be rotated.
  • This multi-purpose staff 32 combines the minute wheel staff and the setting stem into a common staff which thus serves several purposes, namely to carry the minute wheel and to cause a hand adjustment by the setting crown.
  • FIG. 6 shows a variation of the form of construction of FIGS. 1 to 5. Since the parts do not completely correspond with the parts of the form of construction of FIG. 1, they are mentioned again.
  • the bearing tube 81 is fixed in a frame plate 80 in which a fourth wheel staff 82 is pivoted at 83 and 84.
  • the fourth wheel staff 82 carries on its upper end a fourth wheel .85 and a fourth pinion 86.
  • the second hand (not shown) is connected to staff 82.
  • a center tube 88 rotates on tube 81 and carries a center wheel 87.
  • An hour tube 89 rotates on center tube 88.
  • Hour tube 89 is integral with an hour wheel 90 which engages with a minute pinion 91 which is fixed on a multi-purpose staff 92.
  • Staff 92 pivots in a frame plate 89.
  • the staff 92 carries a minute pinion and a minute wheel 93 which engages in the center wheel 87.
  • the setting crown and the coupling spring correspond with the parts shown in the form of construction of FIGS. 1 to and they are labeled with the same reference symbols.
  • the coupling disc 193 has recesses 94 and 95 for the fingers 51 and 55 and a coupling hole 96 with which a coupling square cooperates.
  • a coupling bushing 98 is fixed on the multi-purpose staff 92.
  • Disc 99 prevents the dropping out of the coupling disc 193, when the whole watch movement is taken out of the watch case 44, since this positioning disc has a larger diameter than the coupling hole 96.
  • the method of operation of this form of construction is the same as in the form of FIGS. 1-5.
  • the motion transmission from the setting stem to the setting organ can be laid out by corresponding transmission members in such a manner that the motion of the setting stem to the setting organ is such that the setting organ is arranged on the surface of the case.
  • the coupling and the setting organ are coaxial with the setting stem.
  • This arrangement permits an easy assembly of the parts so that the setting organ is positioned on a case part, i.e. on the case bottom, and can be moved into a coupling position and into an uncoupling position.
  • the coupling itof the coupling is placed on the setting stem or connected with it and the second half of the coupling is arranged on the movement, i.e. on a frame plate or a bridge which self is separated from this setting organ.
  • the first half forms a part of the total watch movement.
