Definitions
- the present invention relates to a timepiece comprising a striking mechanism combining a repeater mechanism, indicating the current time by sound on demand, and an alarm or clock mechanism.
- Such a timepiece is described in patent CH 703635 of the present applicant.
- the alarm mechanism it comprises uses the quarter and minute parts and the hour rack of the repeater mechanism to sound the alarm time, but holds them back before they come into contact with their snails. respectively until the current time coincides with the alarm time programmed by the user.
- First and second pushers present on the case of the timepiece allow the user to respectively activate the repeater mechanism, to ring the current time, and the alarm mechanism.
- the snooze mechanism cannot be triggered.
- a display device indicates the state, activated or deactivated, of the alarm mechanism.
- This timepiece according to patent CH 703635 has the disadvantage of requiring, as a source of energy for the repeater and alarm mechanisms, a striking barrel that can be wound by a winding crown.
- This barrel must be able to store a large amount of energy, therefore be large in size, to avoid the user having to wind it often.
- it requires in practice to provide a display of its energy reserve so that the user can know when to wind it up, and the user must remember to check the energy level before activating the repetition or the alarm.
- a timepiece in particular a wristwatch, a pocket watch, a pendant watch or a clock, comprising a striking mechanism that can operate in a repeat mode or an alarm mode, a source of mechanical energy for powering the striking mechanism and manual control members for controlling the striking mechanism, the striking mechanism being arranged to produce an audible indication of the current time when the repeat mode is activated and to produce at an hour alarm determined an audible indication of said alarm time when the alarm mode is activated, characterized in that the manual control members comprise a first manual control member making it possible to select one or the other of the repeat and alarm and a second manual control device for arming the mechanical energy source and activating the selected mode.
- the energy source As the energy source is armed before each chime, it can be small, like the barrels of traditional repeater mechanisms without an alarm. In addition, the arming of the energy source is transparent for the user, since it is the same control member, preferably a lock, which allows this arming and the activation of the repeat or alarm mode. It should also be noted that the fact of activating the repeat mode and the alarm mode by means of the same control device provides ease of use.

- FIGS. 38 and 39 are top views showing isolation devices respectively allowing the selection of the minute repeater or alarm mode and the ringing of the alarm when a crown of the timepiece is in an axial winding position (figure 38) and respectively preventing the selection of the minute repeater or alarm mode and the ringing of the alarm when the winding stem is in an axial reset position the hour (figure 39).
- a timepiece according to the invention which in the example illustrated is a wristwatch, comprises a case 2 containing a base movement, a striking mechanism connected to the base movement, a dial 8 and indicator hands or other indicator members associated with dial 8.
- the indicator hands typically comprise an hour indicator hand 10, a minute indicator hand 12 and a seconds indicator hand 14 actuated by the basic movement, as well as a 16 hour alarm hand.
- the winding crown 18 can occupy three axial positions: a pushed position, an intermediate position and a pulled position. In the pushed position, a clockwise rotation of the winding crown 18 winds the basic movement. In the intermediate position, turning the winding crown 18 clockwise or anti-clockwise allows you to set an alarm time. In the pulled out position, turning the winding crown 18 clockwise or anti-clockwise sets the current time (time of the basic movement).
- the selection pusher 20 passes coaxially through the winding crown 18 and is axially movable relative to the latter. The selection pusher 20 could nevertheless be separated from the winding crown 18.
- the striking mechanism has a minute repeater operating mode and an operating mode alarm, the passage from one mode to the other being effected by means of the selection button 20.
- an actuation of the activation lock 22 that is to say a sliding of the activation lock 22 on the periphery of the case 2 between a rest position and an end position , switches the striking mechanism from a selected minute repeater state (block a) to an activated minute repeater state (block b) by triggering the striking of the hours, quarters and minutes of the current time.
- the chime mechanism remains in minute repeater mode until selection pusher 20 is pressed.
- an actuation of the activation lock 22 causes the ringing mechanism to pass from a selected alarm state (block c), where the ringing mechanism is inactive, to an activated alarm state (block d), where the striking mechanism waits for the current time to reach a determined alarm time before triggering the striking of the hours, quarters and minutes of said alarm time (block e). Once the alarm time has been sounded, the alarm mechanism returns to its selected alarm state (block c).
- Said determined alarm time may be an alarm time programmed by the user, indicated by the alarm hour hand 16, or an alarm time depending on an alarm time programmed by the user.
- the alarm time can only be set by the user in steps of fifteen minutes over twelve hours, either at the full hour, the hour and a quarter, the hour and a half or the hour. hour and three quarters, and said determined alarm time at which the bell is triggered is the alarm time programmed by the user less one or two minutes, in order to increase the number of strokes to ring and make the time indication particularly audible to the user.
- the activation lock 22 has not been activated, it is possible to switch from one operating mode to another, from minute repeater to alarm and vice versa, by pressing the selection button 20.
- the user can, by pressing the selection button 20, return to minute repeater mode where he can ring the current time at any time by activating the activation lock 22.
- minute repeater or alarm it is not possible to stop the ringtone when it has been triggered The user must wait for the end of the ringtone before being able to start a new one maneuver on the timepiece.
- the travel of the activation lock 22 in the alarm mode is the same as in the minute repeater mode and does not depend on the number of strokes to be sounded, as will be explained later.
- the two modes of operation use the same energy source consisting of a striking barrel 24 (cf. figure 2) independent of the barrel of the base movement.
- the basic movement and the striking mechanism are mounted on a frame (not shown) conventionally made up of a plate and bridges.
- the basic movement (not shown) is of the traditional type. It is located on the bridge side and comprises a barrel acting as a power source, a going train, an escapement and a balance-spring or other resonator.
- the basic movement can be supplemented by an automatic winding mechanism arranged to wind the barrel using the energy released by the movements of the wearer of the timepiece.
- the striking mechanism designated by 6 in the drawings, is located partly on the bridge side and partly on the dial side, but mainly on the dial side.
- On the bridge side (FIG. 2), there are hammers 40, 42 and gongs 44, 46, as well as the striking barrel 24, a speed regulator 48, for example of the inertial flywheel type, and a striking gear train 50 connecting the bell barrel 24 to the speed regulator 48.
- the rest of the striking mechanism 6 (see Figure 12) is located on the dial side.
- the striking barrel 24 (cf. FIGS. 4, 5, 6 and 10) consists of a barrel drum 52 housing a spiral barrel spring 54 and a toothing 56 integral with the barrel drum 52.
- the barrel drum barrel 52 is traversed, in a free rotation manner, by a barrel shaft 58 to which is attached the inner end of the barrel spring 54, the outer end of the barrel spring 54 being itself coupled to the wall of the drum of barrel 52 by a sliding flange 60, as will be explained later.
- a spindle wheel 62 integral in rotation with the barrel arbor 58 On the barrel arbor 58, above the striking barrel 24, are also mounted, in order, a spindle wheel 62 integral in rotation with the barrel arbor 58, a trigger ratchet 64 free in rotation with respect to the barrel arbor 58 and which a spring 66 (visible in FIG. 27) prevents from moving back, and a drive plate 68 integral in rotation with the barrel arbor 58.
- the trigger ratchet 64 is held axially by two bearing screws 70 which pass through elongated holes 72 of the detent ratchet 64 to be screwed into the drive plate 68.
- the elongated holes 72 allow limited rotation of the detent ratchet 64 relative to the drive plate 68.
- the drive plate 68 carries a detent pawl 74 and a return spring 76 of the detent pawl.
- a pin 78 carried by the trigger ratchet 64 passes through an opening 80 of the drive plate 68 large enough not to impede the rotation of the latter. This pin 78 has the function of moving the trigger pawl 74 outwards, the end of which has an inclined surface 82 for this purpose.
- the trigger pawl 74 is arranged to cooperate, via an engagement lug 84 which it comprises, with a barrel ratchet 86 free to rotate around a barrel 88 of the escape plate 68.
- a ratchet of 90 hours Around the barrel of the ratchet to barrel 86 are mounted a ratchet of 90 hours, a rack pinion on rocket 92, a piece pinion of quarters 94 and a piece control finger quarters 96.
- the hours ratchet 90, the rack pinion on the fusee 92 and the quarters part control finger 96 are integral in rotation with the barrel ratchet 86.
- the quarters part pinion 94 is free in rotation relative to the barrel ratchet 86 but is controlled by the quarters piece control finger 96 via a pin 98 carried by the quarters piece pinion 94.
- the assembly 64, 68, 86, 90 , 92, 94, 96 is held axially in one direction by a shoulder 100 of the barrel shaft 58 against which the drive plate 68 can rest and in the other direction by a nut 102 screwed onto one end of the barrel arbor 58.
- the assembly 64, 68, 86, 90, 92, 94, 96 is located on the dial side while the striking barrel 24 and the fuse wheel 62 are located on the bridge side.
- the assembly 64, 68, 86, 90, 92, 94, 96 constitutes a detent fuse of the type found in grand alarm mechanisms where the alarm can be triggered manually (on demand) or automatically (by the way). It makes it possible to decouple the striking barrel 24 from the parts used to actuate the hammers 40, 42 to authorize the taking of information of the number of strokes to be sounded and to couple the striking barrel 24 to the said parts used to actuate the hammers 40, 42 after taking information to ring the bell.
- the barrel drum 52 by its teeth 56, meshes with the wheel 104 of a one-way clutch wheel set 106 (cf. FIGS. 7 and 8).
- control 112 is pivotable about a point 114 and has a slot 116 in which is engaged a fixed pin 118 (visible in Figure 27) acting as a stop defining two limit positions of the control rack 112, namely a position of rest and an end position.
- a rack return spring 120 acts on the control rack 112 for the maintain in its rest position when it is not actuated by the activation lock 22.
- the control rack 112 is used to arm the barrel spring 54 via the barrel drum 52.
- a pawl 122 engaged in the toothing 56 under the action of a pawl return spring 123 prevents the striking barrel 24 from being unwound by the barrel drum 52.
- the control rack 112 also serves to actuate a winding pawl 124 positioned by a winding pawl spring 126 - the winding pawl 124 and the winding pawl spring 126 are visible in Figure 27 - to set the detent ratchet 64 in motion and thereby disengage the detent pawl 74, plus precisely its engagement lug 84, of the teeth of the barrel ratchet 86 by means of the pin 78 carried by the trigger ratchet 64.
- the wheel 104 and the pinion 108 of the one-way clutch mobile 106 are fixed in rotation in one direction and free in rotation with respect to each other in the other direction.
- the movement of the control rack 112 by the activation lock 22 rotates the pinion 108 in the direction in which it is integral with the wheel 104.
- the wheel 104 driven by the pinion 108 in turn drives the barrel drum 52 , which arms the barrel spring 54.
- each actuation of the activation lock 22 raises the striking barrel 24.
- control rack 112 is abandoned to the action of its spring 120 and returns to its rest position by rotating pinion 108 but not wheel 104 which, in this sense, is disengaged from pinion 108 and retained by toothing 56 itself retained by pawl 122.
- the control rack 112 For its drive by the activation lock 22, the control rack 112 comprises an arm 128 that a pin (not shown) carried by the activation lock 22 can push against the action of the rack return spring 120 and against the action of a return spring of the activation lock 22.
- the activation lock 22 is movable between a rest position where its return spring presses it against an abutment of the box 2 and an end position race where it bears against the control rack 112 itself at the end of the race against the pin 118 (see Figure 28).
- the one-way clutch wheel set 106 (cf. FIG. 9) is for example as described in the applicant's international patent application no. PCT/IB2020/060506.
- the wheel 104 comprises an internal toothing 132 with asymmetrical teeth which delimits a housing 134 in which there are a rigid pawl 136, a rigid drive member 138 and an elastic blade 140 connecting the rigid pawl 136 to the rigid drive member 138.
- the rigid drive member 138 is integral in rotation with the pinion 108.
- the wheel 104 is mounted loose around the axis 142 of the pinion 108 and is made integral with the pinion 108 in one direction of rotation by the rigid pawl 136 blocked by the rigid drive member 138 against a tooth of the internal toothing 132. In the other direction of rotation, the rigid pawl 136 clicks and thus separates the wheel 104 from the pinion 108
- the striking barrel 24 has a sliding flange 60. It is therefore a barrel which resembles that of self-winding watches, the sliding flange 60 serving to avoid any excess tension in the barrel spring 54 .
- the striking barrel 24 in the present invention is fully charged each time the activation lock 22 is actuated. , this in order to guarantee sufficient energy for the maximum number of strokes that the striking mechanism 6 may have to ring according to the alarm time that the user has programmed. In the majority of cases, therefore, after a ringing, energy remains in the ringing barrel 24. As the stroke of the activation lock 22 is the same whatever the number of strokes to ring and the mode of operation , the actuation of the activation lock 22 for the next ring brings a surplus of energy which it is useful to evacuate to avoid a breakage of the spring of barrel 54.
- This sliding flange 60 is shown in Figure 10. It may include protrusions 144 cooperating with corresponding notches made in the wall of the barrel drum 52 to index positions of the sliding flange 60 along said wall between which the sliding flange 60 can slip if the mainspring 54 is over-tensioned.
- the stub wheel 62 is kinematically connected to the speed regulator 48 via the ring gear 50, also called "small gear", which is a multiplier gear.
- the speed regulator 48 makes it possible to regulate the speed of rotation of the striking wheel 50 and of the barrel arbor 58.
- a helix 146 for locking and unlocking the striking wheel 50 is coaxial with and integral with the speed regulator 48.
- the output torque of the striking wheel 50 is very low, so that a simple tangent contact on the helix 146 suffices to stop the entire striking wheel 50 and the barrel arbor 58. This tangent contact is ensured by a lever propeller stopper 148 when the latter is constrained by a quarter piece 150 as shown in Figure 11.
- the quarter part 150 comprises on its periphery two series 152, 154 of three teeth.
- the first series 152 is intended to cause a first lifting of the quarters (not shown) raising a small hammer 42 striking a high pitch 46 (cf. figures 11 and 3), and the second series 154 is intended to cause a second lifting of the quarters (not shown) raising a large hammer 40 striking a low gong 44.
- the quarter piece 150 further has an internal toothing 156 meshing with the quarter piece pinion 94.
- the piece quarters 150 also has a quarters feeler 158. This quarters feeler 158 is arranged to rest on the rungs of a quarters cochlea 160 (see FIGS.
- the quarter cochlea 160 is coaxial with the floor of the basic movement. In addition, it carries a pin 164 which, at each turn of the roadway, advances a twelve-pointed star 166 carrying a cochlea of hours 168 by one tooth.
- the barrel ratchet 86 In the rest state of the striking mechanism 6 (selected minute repeater state or selected alarm), the barrel ratchet 86 is secured to the barrel arbor 58 by the cooperation between the trigger pawl 74 and the barrel ratchet 86, and the quarter piece 150 subjected to the action of the barrel arbor 58 via the barrel ratchet 86, the quarter piece control finger 96 and the quarter piece pinion 94 is blocked by helix 146 in a raised position, away from the quarters cochlea 160, against the force of the quarters piece return spring 162.
- a cochlea of minutes 170 (cf. figure 14) is coaxial and integral with the roadway. On the rungs of this 170-minute cochlea can come to rest a 172-minute feeler of a 174-minute piece to determine the number of minutes to strike.
- the minute part 174 is mounted on the same axis 176 as the quarter part 150 and is subjected to the action of a minute part return spring 178.
- the minute part 174 is provided with a first toothed sector 180 of fourteen teeth intended to cause lifting of the minutes lifting the small hammer 42.
- the minute part 174 comprises a second toothed sector 182 which cooperates in a traditional manner with a minute hook 184 carried by the quarter part 150 .
- the 90-hour ratchet is intended to drive a lifting of the hours raising the large hammer 40.
- the rack pinion on a rocket 92 integral with the 90-hour ratchet, meshes with the toothed sector 186 of a 188-hour rack or rake ( see Figures 4 to 6 and 12) subjected to the action of an hour rack return spring 190 and which comprises an hour feeler 192 capable of coming to rest on the rungs of the hour cochlea 168 to determine the number of hours to ring.
- a pin 194 carried by the quarter piece 150 serves to retain the hour rack 188 for a certain time during the fall of the quarter piece 150 towards the quarter cochlea 160.
- the quarter cochlea 160 and minutes cochlea 170 is mounted freely a surprise 196.
- a pin 198 implanted in the minutes cochlea 170 and engaged in a larger hole 200 of the surprise 196 limit the rotational mobility of the surprise 196 with respect to the minute cochlea 170.
- the quarter cochlea 160 is integral with the surprise 196 and defines a spring 202 which acts on the pin 198. This spring 202 tends to align the surprise 196 angularly with the cochlea of 170 minutes.
- the function of a surprise is to lengthen the 0 rung of each arm of the minute cochlea when no minute is to strike, in order to prevent the minute feeler from falling untimely on the fourteenth rung of the adjacent branch.
- the surprise 196 is activated before each striking, when the hour to strike is an hour without a minute to strike or an hour which slightly precedes (typically by one or two minutes) an hour without a minute to strike, by a quarter jumper 204 which shifts it angularly with respect to the minutes cochlea 170 against the action of the spring 202. After the ringing, the surprise 196 returns to the rest position.
- the activation of the surprise 196 does not occur during the actuation of the activation lock 22, as in a classic minute repeater, but during the fall of the parts of the quarters 150 and the minutes 174 and of the hour rack 188 on their snails 160, 170, 168, more precisely during the fall of the hour rack 188.
- the quarter jumper 204 is controlled by the hour rack 188 via a pin 206 carried by the hour rack 188 and against which an arm of the quarter jumper 204 rests under the action of a quarter jumper return spring 208. Each time the hour rack 188 falls towards the hour cochlea 168, it allows the quarter jumper 204 to approach the surprise 196.
- This movement of the quarter jumper 204 has most of the time no effect on the surprise 196 given the angular position of that here, but when the hour to strike is an hour without a minute to strike or an hour which slightly precedes an hour without a minute to strike, the quarter jumper 204 comes into contact with the surprise 196 to shift it angularly with respect to the minute cochlea 170.
- the quarter jumper 204 is only in the way of the surprise 196 during the striking phase and does not need to be raised every quarters of an hour by the surprise 196 between the moment when the alarm is activated by the actuation of the activation lock 22 and the moment when the current time coincides with the determined alarm time. Energy consumption is thus reduced.
- the 174 minute coin may be very close to the 170 minute cochlea. The time it takes for the 174 minute coin to fall to the 170 minute cochlea may be too short to allow the 188 hour rack to activate the 196 surprise.
- the mechanism of chime 6 is provided with a 210 minute blocker arranged to delay the fall of the 174 minute piece until the 196 surprise is activated by the 188 hour rack.
- the minute blocker 210 is particularly visible in figure 14. It pivots around a point 212 and its rest position is defined by a pin 214 against which it rests under the action of a return spring 216.
- a first arm 218 of the minute blocker 210 acts as a stop for a pin 220 carried by the minute piece 174 to stop the minute piece 174 when the quarter piece 150, the minute piece 174 and the hour rack 188.
- a second arm 222 of the minute blocker 210 is struck by the pin 206 of the hour rack 188 after the hour rack 188 let the quarter jumper 204 move towards the surprise 196 to activate it or not depending on the hour to ring.
- This cooperation between the 188 hour rack and the 210 minute blocker raises the 210 minute blocker and releases the 174 minute piece which can thus fall on the 170 minute cochlea to take the information of the number of minutes to ring.
- the striking mechanism 6 comprises (cf. FIGS. 15 to 20) a column wheel 224 consisting of a ratchet 226, a stage of columns 228 and of a cap 230, these three elements 226, 228, 230 being mounted integral around a column wheel axle 232.
- the column wheel 224 is positioned by a jumper 234 cooperating with the ratchet 226. It is driven by the selection pusher 20 via, successively, an intermediate rocker 236, a control 238 and a control hook 240 (more visible in FIG. 36) engaged in the toothing of the ratchet 226.
- the ratchet 226 has twelve teeth and the stage of columns 228 six columns.
- the active faces RM of the columns of the stage of columns 228 correspond to the minute repeater mode while the voids AL between two columns correspond to the alarm mode.
- the cap 230 is located in the example illustrated between the ratchet 226 and the stage of columns 228. It has in its lower face, that is to say the face farthest from the stage of columns 228, a recess 242 which surrounds the column wheel axle 232.
- the two walls which laterally delimit the recess 242 constitute star-shaped cams for the inner wall 244 and of generally polygonal shape for the outer wall 246.
- the vertices RM of the star and the polygon are aligned angularly with the active faces RM of the columns and also correspond to the minute repeater mode.
- the zones AL of the hollow 242 between the vertices RM correspond to the alarm mode.
- Each actuation of the selection pusher 20 moves the column wheel 224 by one ratchet tooth and causes the striking mechanism 6 to pass from one mode of operation to another.
- the principle of operating mode selection is to allow quarter coin 150 to drop immediately after actuation of activation lock 22 when striking mechanism 6 is in minute repeater mode, to trigger the striking hours, quarters and minutes of the current time, and to prevent the quarter piece 150 from falling beyond an intermediate standby position, until the current time corresponds to the determined alarm time, when the striking mechanism 6 is in the alarm mode.
- a secondary alarm trigger rocker 248 is used pivoted around a point 250 and which carries at one end a first pin 252 and at another end a second pin 254 ( Figure 20) engaged in the recess 242 of the cap 230.
- On the first pin 252 acts an alarm trigger rocker jumper 256 subjected to the action of a jumper spring 258.
- the alarm trigger rocker jumper 256 has two inclined surfaces 260, 262 forming an angle between them.
- pressing the first inclined surface 260 of the alarm trigger rocker jumper 256 on the first pin 252 keeps the second pin 254 bearing against the outer wall 246 of the recess 242 in an RM zone and keeps the first pin 252 out of the path of gyration of an abutment 264 defined by an extension 266 of the quarter piece 150 - abutment 264 which is in an arc of a concentric circle with the quarter piece 150.
- the piece of quarters 150 is free to fall on the cochlea of quarters 160 upon actuation of the activation lock 22.
- the secondary alarm triggering rocker 248 prevents a primary alarm triggering rocker 268 from touching an output cam 270 of an alarm differential 272, as will be explained later.
- the purely “alarm” part of the striking mechanism 6 is thus disconnected from the rest of the mechanism 6 and does not induce any energy consumption in the basic movement.
- the support of the second inclined surface 262 of the alarm trigger rocker jumper 256 on the first pin 252 keeps the latter in the path of gyration of the stop 264 of the quarters piece 150 and therefore prevents the quarters piece 150 from falling on the quarters cochlea 160 and triggering the bell.
- the quarter piece 150 stops on the first pin 252, which corresponds to the intermediate waiting position mentioned upper. In this position, the second pin 254 is not in contact with either of the two walls 244, 246 of the recess 242 and the secondary alarm trigger rocker 248 is retained by the primary alarm trigger rocker 268 which, here , is in contact with the output cam 270 of the alarm differential 272.
- the secondary alarm trigger flip-flop 248 For its cooperation with the primary alarm trigger flip-flop 268, the secondary alarm trigger flip-flop 248 is provided with a tab 274.
- the secondary alarm trigger flip-flop 248 further comprises a finger 276 capable of cooperating with a nut on the floor 278, coaxial with and integral with the floor of the basic movement, having four notches 280 (cf. FIG. 21) representative of the quarters to ring in the alarm mode.
- the primary alarm trigger rocker 268 comprises on its periphery two lugs 282, 284 capable of interacting with the lug 274 of the secondary alarm trigger rocker 248 and an arm 286 passing under the cam output 270 of the alarm differential 272 and whose end is surmounted by a lug 288 arranged to cooperate with this output cam 270.
- the primary alarm trigger rocker 268 is pivoted not around a physical axis but around a virtual axis by means of a flexible guide 290 suspending it from a fixed base 292.
- the alarm differential 272 is used to compare the current time to the determined alarm time.
- Two diametrically opposed notches 294 made in the output cam 270 define two angular positions of the output cam 270 (one per twelve o'clock) in which the current time coincides with the determined alarm time.
- the high rotational speed of the road relative to the output cam 270 allows the four notches 280 of the road nut 278 to refine the determination of when the alarm sound should be triggered.
- the 278 pavement nut is indexed to the 170 minute cochlea for a trip one or two minutes before the quarter.
- the output cam 270 is indexed so that the primary trigger occurs a little before the trigger on the road nut 278.
- the alarm differential 272 comprises, around a differential axis 296, a programming wheel 298, a programming pinion 300, a satellite wheel 302, an output wheel 304 and the output cam 270 integral with output wheel 304.
- Programming wheel and pinion 298, 300 are integral with differential shaft 296 and their angular position is maintained by jumper 306 acting on programming wheel 298.
- satellite wheel 302 and output wheel 304 are mounted loose.
- the satellite wheel 302 carries a satellite 308 which meshes on the one hand with the programming pinion 300 and on the other hand with the output wheel 304.
- the output wheel 304 and the output cam 270 rotate at the rate of a turn per twenty-four hours.
- the programming wheel 298 and the satellite wheel 302 are the two inputs of the differential alarm 272. They represent respectively the alarm time programmed by the user and the current time.
- the satellite wheel 302 is kinematically connected, by two references 310, to the hour wheel 312 of the basic movement, coaxial with the roadway. Traditionally, the hour wheel 312 meshes with a timer pinion 314 and the roadway meshes with a timer wheel 316.
- An alarm display wheel 318 is mounted coaxially to the hour wheel 312 and to the roadway and freely rotatable with respect thereto.
- This alarm display wheel 318 is kinematically connected to the programming wheel 298 by a reference 320.
- This alarm display wheel 318 carries the alarm hour hand 16 indicating on the dial 8 the alarm time programmed by the user (cf. figure 1) and preferably moving in quarter-hour steps.
- a locking lever called "bird" 322 pivotally mounted around a point 324, comprises a first beak 326 which cooperates with a beak 328 of the room quarters 150 in minute repeater mode to prevent the quarters piece 150 from falling as long as the activation lock 22 has not reached the end of its travel (cf. FIG. 12).
- This characteristic makes it possible to guarantee the smooth running of the sequence by preventing the quarter piece 150, after having been released, from rising under the action of the striking cylinder 24 without having been able to feel the quarter snail 160.
- the bird 322 is coupled to a shift blocker 330 which is pivoted around a point 332 and which a return spring 333 tends to rotate clockwise in Figures 12 and 13.
- the coupling of the bird 322 and quarter blocker 330 is achieved by the physical axis of rotation of the bird 322 which passes through an oblong hole 334 of the quarter blocker 330 and by a pin 336 carried by the bird 322 which passes through another oblong hole 338 of the quarter blocker 330, the two oblong holes 334, 338 having different orientations.
- the quarter blocker 330 comprises a main part - the part coupled to the bird 322 - and an arm 340 rigidly connected to the main part and passing over the column wheel 224.
- the end of the arm 340 has on its face a lug 342 which cooperates with the stage of columns 228 of the column wheel 224.
- the shift blocker 330 is thus controlled by the column wheel 224. columns and gaps between the columns are reversed, the columns corresponding to the alarm mode and the gaps between the columns to the minute repeater mode.
- a pin 344 carried by the control rack 112 acts on a finger of the bird 322 to cause the bird 322 and release the quarters piece 150.
- the quarters blocker 330 is positioned by the column wheel 224 so that the bird 322 is moved away from the beak 328 of the quarters piece. quarters 150 and cannot retain the coin of quarters 150.
- the function of the bird 322 is indeed filled, in the alarm mode, by the secondary alarm trigger flip-flop 248 and its pin 252.
- the bird 322 also allows the striking mechanism 6 to return to minute repeater mode when the user actuates the selection pusher 20 while the striking mechanism 6 is in the activated alarm state (transition from the block of to block a in figure 3).
- the quarter piece 150 is blocked by the pin 252 of the secondary alarm trigger rocker 248.
- a rotation one step of the column wheel 224 caused by the actuation of the selection pusher 20 causes the shift blocker 330 to pivot, which itself actuates the bird 322 so that a second beak 346 of the latter, adjacent to the first spout 326, comes to be placed in the path of the spout 328 of the quarter piece 150 (cf. FIG.
- the second beak 346 of the bird 322 retains the quarter piece 150 in a lower position than its high rest position and than its position on the first beak 326 of the bird 322.
- the quarter piece 150 blocks the propeller 146, and therefore the speed regulator 48 and the barrel shaft 58, via the propeller stop lever 148.
- the propeller 146 In its intermediate standby position (alarm activated state), the propeller 146 is blocked by a leg 348 of the secondary alarm trigger rocker 248.
- the propeller 146 is released and the barrel arbor 58 drives the drive plate 68 which causes the pawl to plunge back trigger 74 in the teeth of the barrel ratchet 86 and raises the quarter piece 150 to its high rest position, the bird 322 disappearing when the beak 328 of the quarter piece 150 passes the first beak 326.
- the column wheel 224 sets the bird 322 into the path of the beak 328 of the quarter piece 150 and, in conjunction with the alarm trigger toggle jumper 256, places the secondary alarm trigger toggle 248 and its pin 252 out of the way of the stop 264 of the quarter piece 150.
- the user can then, at any time, trigger the minute repeater chime by sliding the activation lock 22 on the edge of the box 2 from its rest position until to its end position.
- This displacement of the activation lock 22 arms the striking barrel 24 via the control rack 112 and the one-way clutch mobile 106.
- a pin 350 mounted on control rack 112 actuates winding pawl 124.
- Winding pawl 124 drives detent ratchet 64 on which pin 78 is mounted.
- Pin 78 raises detent pawl 74 against the action of its spring 76 to bring it out of the teeth of the barrel ratchet 86.
- the rack pinion on the fusee 92 which has become free to rotate, is driven by the hour rack 188 itself driven by the hour rack return spring 190.
- the quarters piece pinion 94 is driven by the quarters piece 150 itself driven by the quarters piece return spring 162.
- the quarters piece 150 retains the quarters rack. hours 188.
- the first beak 326 of the bird 322 stops the quarter piece 150 so as not to trigger the chime before the end of the winding of the striking barrel 24.
- the control rack 112 then drives the bird 322 via its pin 344, which releases the 150 quarters coin falling under the impetus of the 162 quarters coin return spring.
- the 150 quarters coin drags the 174 minutes coin via the 184 minutes hook.
- the hour rack 188 is released by the quarter part 150 and falls under the impulse of the hour rack return spring 190.
- the minute hook 184 encounters a fixed element which disengages it from the second toothed sector 182 of the minutes 174, thus separating the quarters piece 150 and the minutes piece 174 which then fall separately under the impulse of their respective return springs 162, 178. During its fall, the minutes piece 174 is slowed down by the minutes stopper 210 until the quarter jumper 204 controlled by the hour rack 188 drops towards the surprise 196 to activate it or not according to the hour to strike.
- the quarter piece 150, the hour rack 188 and the minute piece 174 then feel their respective snails 160, 168, 170 to read the number of strokes to be struck.
- the speed regulator 48, the striking gear 50 and the barrel arbor 58 are released.
- the drive plate 68 integral with the barrel arbor 54 begins to rotate.
- the trigger pawl 74 which it carries moves away from the pin 78 mounted on the trigger ratchet 64 and plunges into the toothing of the barrel ratchet 86.
- the elements 86, 90, 92 and 96 are again integral in rotation with the barrel arbor 58.
- the rack pinion on a fusee 92 raises the hour rack 188 and the hour ratchet 90 activates the hour lift to strike the hours (one stroke per hour).
- the quarters piece control finger 96 catches up with the pin 98 carried by the quarters piece pinion 94 and drives the latter to raise the quarters piece 150 to its high rest position where it will again block the gear 48, the striking wheel 50 and the barrel arbor 58.
- the quarter piece 150 actuates the lifted from the quarters to strike the quarters (two strokes per quarter) then drives the 174 minutes piece through the 184 minutes hook which fell back into the second 182 toothed sector of the 174 minutes piece.
- the 174 minutes piece then activates the minute lifter to ring the minutes (one strike per minute).
- the rack return spring 120 returns the control rack 112 to the rest position, this return being made possible by the disengagement carried out by the one-way clutch mobile 106 .
- the column wheel 224 When, now, the user selects the alarm mode by pressing the selection button 20 (alarm state selected), the column wheel 224, via the shift blocker 330, puts the bird 322 out of the way. of the beak 328 of the quarter piece 150 and, in collaboration with the alarm trigger rocker jumper 256, puts the secondary alarm trigger rocker 248, more precisely its first pin 252, in the path of the stop 264 quarters room 150.
- the user can then, at any time, trigger the alarm by sliding the activation lock 22 on the perimeter of the box 2 from its rest position to its end position. race.
- This displacement of the activation lock 22 arms the striking barrel 24 via the control rack 112 and the one-way clutch mobile 106.
- the pin 350 mounted on control rack 112 actuates winding pawl 124.
- Winding pawl 124 drives detent ratchet 64 on which pin 78 is mounted.
- Pin 78 raises detent pawl 74 against the action of its spring 76 to bring it out of the teeth of the barrel ratchet 86.
- the rack pinion on the fusee 92 which has become free to rotate, is driven by the hour rack 188 itself driven by the hour rack return spring 190.
- the pinion piece of the quarters 94 is driven by the quarters piece 150 itself driven by the quarters piece return spring 162.
- the quarters piece 150 drives the minutes piece 174 via the minutes hook 184. Via its pin 194, quarter piece 150 retains hour rack 188. Quarter piece 150 stops on first pin 252 of secondary alarm trip rocker 248, which also stops hour rack 188 and piece of minutes 174. The piece of quarters 150 remains in this intermediate standby position until the current time coincides with the determined alarm time.
- the primary alarm trigger flip-flop 268 rests by its lug 288 against the periphery of the output cam 270 of the alarm differential 272 and the secondary alarm trigger flip-flop 248 is retained by the primary alarm trigger rocker 268 as long as the pin 288 is not opposite a notch 294 of the output cam 270.
- the rocker secondary alarm trigger 248 falls under the impulse of the alarm trigger rocker jumper 256 and its spring 258 until the finger 276 of the secondary alarm trigger rocker 248 abuts on the periphery of the nut on the floor 278.
- the quarter piece 150 is at this time still blocked by the first pin 252 of the secondary alarm trigger rocker 248.
- the additional movement of the secondary alarm trigger rocker 248 that this causes brings the pin 252 in front of a groove 352 (visible in Figure 18) of the extension 266 of the quarter piece 150, groove 352 in an arc of a concentric circle with the quarter piece 150.
- the quarter piece 150 is thus released and can fall onto the 160 quarters cochlea.
- the pin 350 (cf. figure 27) which actuates the winding pawl 124 is carried by the end of an elastic arm 356 of the control rack 112 and the winding pawl 124 is itself elastically deformable.
- the elastic arm 356 and the winding pawl 124 are rigid enough not to substantially flex when the pin 350 actuates the winding pawl 124 at the time of transition from the minute repeater selected state to the minute repeater activated state. or from the selected alarm state to the activated alarm state (see figure 28).
- the action of the pin 350 on the winding pawl 124 and of the winding pawl 124 on the detent ratchet 64 immediately abuts the wall of the elongated holes 72 of the detent ratchet 64 against the bearing screws 70 screwed into the drive plate 68 to lock the detent ratchet 64 and prevent the pin 78 from coming together of the engagement pin 84 of the trigger pawl 74.
- the control rack 112 and the activation lock 22 can nevertheless continue their travel without causing any breakage thanks to the elasticity of the arm 356 and the winding pawl 124 (cf. FIG. 29).
- both arm 356 and winding pawl 124 are elastic to reduce bulk, but only arm 356 or winding pawl 124 could be elastic.
- the return spring 126 of the winding pawl 124 is typically in the form of a spiral, as illustrated, and carries at its inner end a pin 360 which secures this inner end to a rigid mobile base 362 from which the active part, deformable elastically, of the winding pawl 124.
- a winding and time-setting mechanism winds the barrel of the basic movement and sets the current time and the alarm time.
- This winding and time-setting mechanism is illustrated in Figure 23. It comprises the winding crown 18 coaxial with and integral with a winding stem 364, a pull tab 366 controlled by the winding stem 364, a time-setting 368 controlled by pull-bar 366, a sliding pinion 370 integral in rotation with the winding stem 364 but axially movable with respect to the latter, this sliding pinion 370 being controlled by the time-setting rocker 368, a return spring 372 of the time-setting rocker 368 which may be in one piece with the latter, and a winding pinion 374 mounted freely in rotation around the winding stem 364 and connected kinematically to the ratchet of the barrel of the basic movement in a known manner.
- the winding and time-setting mechanism further comprises a corrector lever 376 carrying two transmissions 378, 380 which are permanently engaged with each other.
- This corrector lever 376 is controlled by an extension 382 of the pull tab 366 by means of a pin 384 implanted in the corrector lever 376 and able to move in an L-shaped opening 386 of the pull tab extension 382.
- the first reference 378 carried by the corrector lever 376 is intended to be connected to the wheel of programming 298 via a gear train 388.
- the second transmission 380 is arranged to mesh with the timer wheel 316.
- the winding crown 18 and the winding stem 364 can together assume three axial positions indexed in a known manner by a pull tab jumper spring 390 acting on a pin 392 carried by the pull tab 366. These three positions are a pushed position (position 0) , an intermediate position (position 1) and a pulled position (position 2).
- the pin 384 moves relative to the pull tab 366 in one of the two branches of the L-shaped opening 386 during the passage from position 0 to position 1, and vice versa, of the winding crown 18, and in the other branch of the L-shaped opening 386 when passing from position 1 to position 2, and vice versa, of the winding crown 18.
- the orientation of the L-shaped opening 386 is such that the corrector lever 376 retains its unchanged position between position 0 and position 1 of the winding crown 18 and pivots when the winding crown 18 moves between positions 1 and 2.
- the sliding pinion 370 In position 0 of the winding crown 18, the sliding pinion 370 is pressed by the time-setting rocker 368 and its return spring 372 against the winding pinion 374, so that rotation of the crown 18 in a determined direction winds the barrel of the base movement.
- the time setting rocker 368 Under the action of the pull tab 366, moves the sliding pinion 370 to disengage it from the winding pinion 374 and engage it with the first transmission 378 carried by the corrector lever 376.
- This first transmission 378 is itself in engagement with the gear train 388 via a transmission 394.
- a rotation of the winding crown 18 in one direction or the other modifies the angular position of the programming wheel 298 and consequently of the alarm display wheel 318 and thus allows the user to set the alarm time.
- the pull-bar extension 386 pivots the corrector lever 376 to cause the second reference 380 to engage in the toothing of the timer wheel 316 and to release the first transmission 378 from the toothing of the transmission 394, the sliding pinion 370 being simultaneously moved by the pull tab 366 to remain in contact with the first transmission 378.
- a rotation of the winding crown 18 in a direction or the other modifies the angular position of the timer wheel set 314, 316, of the roadway, of the hour wheel 312 and of the satellite wheel 302, allowing time setting of the basic movement and communication of this information to the alarm differential 272.
- the striking mechanism 6 further comprises a display mechanism designed to assume three states corresponding respectively to the minute repeater mode, to the selected alarm state and to the activated alarm state.
- This display mechanism comprises (cf. FIG. 30) an indicator disc 396 dividing into three angular sectors 398, 400, 402. These three angular sectors 398, 400, 402 are typically materialized by different colors on the indicator disc 396, namely a first color identical to that of dial 8 for the minute repeater mode, a second color for the selected alarm state and a third color for the activated alarm state.
- a window 404 (see Figure 1) made in the dial 8 and having for example the shape of a bell makes visible to the user the color of the angular sector which is below him.
- the indicator disc 396 is coaxial with and integral with a disc positioning toothing 406 (cf. FIG. 31) with which an indicator drive rake 408 is pivoted around a point 409.
- a return spring 410 acting on the rake indicator driver 408 tends to apply a spout 412 of the latter against the stage of columns 228 of the column wheel 224.
- the spout 412 bears against the active face RM of a column (FIGS. 16 and 30) , we are in the minute repeater mode and the position of the indicator disc 396 determined by the indicator drive rack 408 is such that the sector angle 398 associated with the minute repeater mode is located under the aperture 404.
- the beak 412 plunges into a vacuum AL between two columns but is stopped in its fall by a blocking device 414 (FIG. 31).
- This movement of the indicator drive rake 408 causes a corresponding movement of the indicator disk 396 and the angular sector 400 associated with the selected alarm state is placed under the window 404 (FIG. 32).
- the blocking device 414 authorizes an additional displacement of the indicator driving rake 408 causing the beak 412 to plunge even further into the vacuum AL until that the indicator drive rake 408 abuts against a fixed pin 416 (FIG. 33).
- the indicator disc 396 therefore pivots again to place the angular sector 402 corresponding to the activated alarm state under the window 404.
- the blocking device 414 comprises the control disc 354 carrying three pins 418, 420, 422 and subjected to the action a return spiral spring 355 (visible in FIG. 35), a blocking rocker 424 pivoted around a point 426 and of which a fork 428 accommodates the pin 420, and a stop lever 430 pivoted around a point 432 on the indicator drive rake 408.
- the pin 418 is held in contact with the extension 266 of the quarter piece 150 by the action of the return spiral spring 355 on the control disc 354.
- the locking rocker 424 is kinematically connected to the control disc 354, that is to say it pivots when the control disc 354 rotates and is stopped when the control disc command 354 is off.
- the stop lever 430 comprises at one end a finger 434 which bears on a pin 436 implanted in the indicator drive rake 408 and at its other end a pin 438 which cooperates with the locking rocker 424.
- the return spiral spring 355 tends to rotate the control disc 354 clockwise but the quarter piece 150, subjected to the action of the striking barrel 24 and blocked by the propeller 146, retains by its extension 266 the control disk 354.
- the locking rocker 424 is therefore also retained, as is the stop lever 430 which thus prevents the indicator drive rake 408 from pivoting at the - beyond an intermediate position.
- the quarter piece 150 drops to its intermediate standby position where it abuts against the pin 252 of the secondary alarm trigger rocker 248 (FIG. 33), allowing the control disc 354 and thus the locking rocker 424, the stop lever 430 and the indicator drive rake 408 to rotate through an angle, thereby changing the display state to indicate the alarm state activated.
- the 150 watch piece After the alarm time has been reached and the bell has sounded, the 150 watch piece, at the end of the ascent, returns the display to the selected alarm state. During this movement, the third pin 422 of the control disc 354 raises the secondary alarm trigger rocker 248 to return its pin 252 to the path of the stop 264 of the quarter piece 150. In a variant, it is a extension 149 (cf. FIG. 11) of the propeller stop lever 148 controlled by the quarter piece 150, and not the pin 422, which raises the secondary alarm trigger rocker 248 after the ringing of the alarm time.
- the angular position of the indicator disk 396 is linked both to the angular position of the column wheel 224 and to the angular position of the quarter piece 150.
- the column wheel 224 allows passage from the state minute repeater display to selected alarm and the status of selected alarm or activated alarm to minute repeater display. Moving the piece of quarters 150 allows you to switch from the selected alarm display state to activated alarm and, after ringing, to return to return to the selected alarm display state.
- the blocking device 414 of the display mechanism is also used to fulfill an isolation function preventing a time setting (of the basic movement or of the alarm) when the bell is ringing, in order to avoid breakage in the striking mechanism 6, in particular at the level of the snails 160, 168, 170 and the output cam 270.
- the locking rocker 424 comprises a first tab 440 which is out of the way of the time-setting flip-flop 368 when no bell rings, that is to say when the quarter piece 150 is in its upper rest position or in its intermediate standby position where it retains the control disc 354. The user can then freely pull the winding stem 364 to place it in its intermediate axial position for setting the alarm time (position 1) or in its drawn axial position for setting the alarm time.
- Another isolation function is provided in the striking mechanism 6, which consists in preventing a change in the operating mode (minute repeater or alarm) when the bell is ringing, in order to avoid breakage, in particular at the level of the column wheel 224. As shown in FIG. quarters 150 is in its high resting position or in its position intermediary of waiting where it retains the control disc 354. The user can then freely actuate the column wheel 224 via the selection pusher 20.
- the locking rocker 424 raises the control hook 240 to release it from the teeth of the ratchet 226 of the column wheel 224 and holds the control hook 240 out of the teeth of the ratchet 226 until the end of the ascent of the quarter piece 150.
- the interaction between the locking rocker 424 and the control hook 240 is carried out by means of a second leg 442 of the locking rocker 424 and a pin 444 of the control hook 240.
- the striking mechanism 6 further comprises an isolation device, illustrated in Figures 38 and 39, preventing selection of the minute repeater/alarm mode when setting the time (of the basic movement or of the alarm) , this also in order to avoid breakage, in particular at the level of the connection between the primary and secondary alarm trigger flip-flops 248, 268.
- This device comprises an L-shaped extension 446 (better visible in FIGS. 34 and 35) of the pull tab 366 arranged to cooperate with the pin 444 of the control hook 240.
- the winding stem 364 When, on the other hand, the winding stem 364 is placed in the intermediate axial position for setting the alarm time (position 1) or in the drawn axial position for setting the current time (position 2), the 446 extension of the t irette 366 pulls the control hook 240 out of the path of gyration of the ratchet 226 of the column wheel 224 (FIG. 39). The user can press the selection button 20, but this action will have no effect on the column wheel 224.
- the striking mechanism 6 includes an isolation device, also illustrated in Figures 38 and 39, making it possible to deactivate the alarm part of the striking mechanism 6 when setting the time (of the basic movement or of the 'alarm), this also in order to avoid breakage, in particular at the level of the primary and secondary alarm trigger flip-flops 248, 268, in particular when setting the time backwards.
- This device comprises a deactivation rocker 448 coaxial with the time setting rocker 368, subjected to the action of a return spring 450 and controlled by the pull tab 366 and a locking lever 452 controlled by the deactivation rocker 448.
- the locking lever 452 When the winding stem 364 is in the axial winding thrust position ( Figure 38), the locking lever 452 does not act on the primary alarm trigger rocker 268 and the alarm part of the striking mechanism 6 can operate normally.
- the winding stem 364 When, on the other hand, the winding stem 364 is placed in the axial position for setting the alarm time or in the axial position for setting the current time (FIG. 39), the locking lever 452 pushes the primary alarm trigger 268 so as to move the lug 288 away from the output cam 270, thus preventing the alarm from triggering.
- the present invention has been described above in the context of a minute repeater. But it is clear to those skilled in the art that it can be applied to any other repetition, for example a quarter-hour or five-minute repetition.
- the minute repeater or, more generally, repeater function could be part of a grand or petite strike mechanism that the timepiece would include.
- the activation lock 22 could be replaced by a rotating bezel or a pusher, as is known per se.
- the lock and the rotating bezel are preferred to the pusher because they require less force from the user to wind the striking barrel 24.
- the winding of the striking barrel 24 by the control rack 112 could effected by the barrel arbor 58 rather than by the barrel drum 52.
- the fusee 64, 68, 86, 90, 92, 94, 96 would be coupled by a kinematic connection to the barrel drum 52 rather than to the barrel arbor 58.
- Another modification could consist in controlling the quarter jumper 204 and/or the minute blocker 210 by a part other than the hour rack 188 , for example by the piece of quarters 150.
