Description

The determination of working time in companies has been the subject of many developments. We have, in particular, made clock clocks, activated by each employee when he arrives at his job, and then when he leaves. Such a clock, commonly called stamping, allows to check that each employee has done the work due.

It goes without saying that the information thus obtained is of a confidential nature. The employee can only access it upon departure or arrival. These moments are not conducive to the analysis of information, as there are usually many people to arrive or leave at the same time. As a result, it is difficult for the employee to know how much time he has actually spent on his job.

There are also devices to determine the time required to complete a particular task. The knowledge of this time facilitates the billing of work. One of them is described, for example, in the document US 3,719,037 . It has an hour and minute indicator and allows you to display up to half a day. A pusher can control his departure and stop.

While such a solution is well suited to the measurement of the working time of a particular task, it does not allow an employee to satisfactorily follow the time he gives to his employer.

The object of the present invention is to provide a mechanical or electromechanical watch that allows a good perception of the time spent working for a whole week, this time being particularly appreciated by many people to plan their work organization.

In the present description, the position of the components on the watch and in the movement is defined with reference to the position occupied, in a conventional manner, an hour hand arranged in the center of the dial and performing two turns per day.

The watch represented at figure 1 comprises a box 10 and, housed in the latter, a mechanical movement which will be described with reference to the figure 2 , a dial 12 and 14 hour hands and minutes 16. A ring 18, arranged at 3 o'clock, allows the driving of the components of the movement and, optionally, its reassembly.

The watch of the figure 1 further comprises a 24-hour hand 20 arranged at 9 o'clock and performing one revolution per day, an additional time-of-work indication needle coaxial with the needles 14 and 16, and a day-time indicator disc. week 24 appearing behind a window 26 open at noon in the dial 12. A pusher 28, placed at 4 o'clock, is intended to control the needle 22, as will be explained later.

The box 10 is provided with a groove 30, made in its periphery and surrounding the dial 12. Indexes 31 to 36 are mounted in this groove. The index 31 is fixed at noon, while the others, five in number, can slide in the groove with friction. They make it possible to form an adjustable ladder opposite the needle 22, the index 31 giving the zero point while the indexes 32 to 36 each mark the end of a working day.

The information display using the needles 14, 16 and 20, as well as the disc of the days 24, is done in a conventional manner and requires no particular remark.

Needle 22 is driven by movement during working hours only. The mechanism to ensure this training is represented on the figure 2 , seen on the dial side.

The movement comprises a plate 37 serving as a support for the various moving parts, in particular the disk 24. At the periphery of this plate are shown, schematically, the ring 18 and the pusher 28.

The plate 37 carries, on the side opposite to that represented on the figure 2 and, consequently, not visible in the drawing, a barrel serving as a source of energy, a finishing gear driven by the barrel and a mobile, the center wheel, carries a roadway on which is located the needle of minutes 16, an escapement controlled by the gear train and a pendulum powered by the exhaust and whose oscillations define the running of the watch.

The plate 37 bears, on its face shown in FIG. figure 2 , a clockwork gear and time setting that has not, either, been represented and which is driven by the roadway. This wheel has a wheel that makes a turn in twelve hours, carries the needle 14 and is provided with a pinion 38. A wheel of twenty-four hours 40 meshes with the pinion 38. It pivots about an axis A perpendicular to the plate 37and arranged at 9 o'clock. The "24 hours" needle 20 is fixed on this wheel. The pinion 38 and the wheel 40 have a number of teeth in a ratio of 1 to 2, so that the wheel 40 performs a revolution in one day, in the counter-clockwise direction.

The wheel 40 comprises a central shaft 41 and carries a coaxial pinion 42 and a drive finger 43, disposed at its periphery, the functions of which will be specified below.

A rocker 44, intended to control the drive or not of the needle of the working time 22, is pivotally mounted about an axis B perpendicular to platinum 37, arranged at noon. It comprises two fingers 44a and 44b, and a boss 44c, whose functions will be indicated later. In addition, it carries two wheels 46 and 48 and a pinion 50, integral with the wheel 48.

The wheel 46 is rotatably mounted about the axis B. It meshes with the pinion 50. The wheel 48 is arranged in such a way that, depending on the position of the lever 44, it meshes with the pinion 42 or not. The latch 44 thus provides a clutch function, the wheel 48 being driven only when it is engaged with the pinion 42.

A spring 52, integral with the plate 37, bears against the boss 44c and thus generates a torque tending to pivot the latch 44 in the counterclockwise direction.

The shaft 41 passes through the plate 37 and carries, on the opposite side, a cam 54 intended to cooperate with the finger 44a, itself passing through the plate 37 by a cutout 56.

The cam 54, shown on the figure 2a , comprises two cutouts 54a and 54b, each embracing an angle of 60 °, this angle being traveled in 4 hours when the wheel 40 makes a complete turn in 24 hours. The cam 54 is arranged so that the finger 44a engages in the cutouts 54a and 54b during working hours, in this case from 8:00 to 12:00 and from 13:00 to 17:00. When the finger 44a is engaged in one of the cutouts 54a or 54b, the spring 52 thus tends to bring the rocker 44 into the position for which the wheel 48 is engaged with the pinion 42.

The disc, in fact, a ring, twice carries the indications of the days of the week, at its periphery, on its face adjacent to the dial 12. This disc is provided with fourteen teeth 58, only two of which are visible in the drawing, radially extending in the central opening of the ring and intended to cooperate with the drive finger 43. It further comprises two annular sectors 60, only one of which is visible in the drawing, extending radially inward and arranged at the same height as the finger 44b so that it can support it when the days "Saturday" and "Sunday" appear in the window 26. In this way, for these two days, the rocker 44 prevents the clutch of the wheel 48 with the pinion 42.

The movement comprises, in its center, a wheel 62 of working time indicator, disposed over the barrel wheel and carrying the needle 22. The wheel 62 is engaged with the wheel 46 carried by the latch 44. when the finger 44a enters one of the grooves 54a or 54b of the cam 54, the sectors 60 being located, therefore not facing the finger 44b, the wheel 62 is kinematically connected to the wheel 40 and rotates in the clockwise. The numbers of teeth that comprise the pinions 42 and 50 and the wheels 46, 48 and 62 are selected so that the latter travels at an angle of 6 ° per hour, or one turn in 60 hours.

In most cases, the work time due by an employee is less than 60 hours. Therefore, it is necessary that the needle 22 can be reset at the end of each week. This function is provided by the pusher 28 and by a mechanism comprising a hammer 64 and a cam 66 of the spiral type, fixed on the wheel 62.

The hammer 64 pivots on the plate 37 around a C axis arranged around 6 o'clock. It comprises an elastic arm 64a whose end is in abutment against the plate 37 and which generates a torque tending to turn it clockwise and thus keep it resting against the pusher 28. The hammer 64 further comprises a bearing surface 64b disposed opposite the cam 66, so as to bear against the latter when acting on the pusher 28. More specifically, the hammer 64 rotates the cam 66, and with it the wheel 62 and the needle 22, until it is at noon. Finally, the hammer 64 forms a stop 64c, close to the bearing surface 64b, whose function is to prevent an untimely zeroing, as will be explained later.

It is clear that the zeroing of the needle 22 must be done at the end of the workweek, when the latch 44 is disengaged. In this way, only the wheels 46 and 48 and the pinion 50 rotate with the wheel 62. If it were not the case, all the clockwork could be driven, which would change the display of the time.

To avoid any inadvertent manipulation, the movement comprises a latch 68 and a spring 70, arranged in the space between the hammer 64 and the latch 44. The latch 68 pivots about an axis D. It comprises a finger 68a and a boss 68b, against which is applied the spring 70 which generates a couple holding the finger 68a in abutment against the latch 64. The latch 68 is arranged in such a way that a portion 68c forms a striker and is or is not in the the space swept by the hammer 64, depending on whether or not the latch 44 has the clutch function. It is thus not possible to apply the hammer 64 to the cam 66 when the wheel 62 is driven.

In the example just given, the working time is scheduled from 8 to 12 hours, then from 13 to 17 hours. However, it is clear that schedules can vary considerably from one company to another or depending on the country. Therefore, the cam 54 is disposed on the side of the movement opposite the dial 12. It is thus possible to replace it with another corresponding to the current schedule. These cams can be easily manufactured by milling, on an ad hoc pose. They are then put in place by any watchmaker.

The mechanism described with reference to figures 1 and 2 is well suited for people working on a regular schedule. It is, however, of little interest to companies practicing free time. The watch represented in Figures 3 to 5 offers the bearer the opportunity to follow his work program.

The figure 3 presents this watch, as it is seen by the wearer. It comprises a box 100 forming a housing in which there is a movement, which is not visible in this figure and which will be partially described with reference to figures 4 and 5 , a dial 102 disposed on the movement, and hour hands 104 and minutes 106, mounted coaxially on the movement and pivoting about an axis arranged at noon, in the middle portion of the dial 102. The movement is controlled by a winding crown and reset time 108, which carries a rod, not visible in the drawing, which passes through the box 100 and allows the driving of movement components.

The indications relating to the working time are displayed by means of three hands, respectively say the working time done 110, the working time due 112 and the time reported 114. More precisely, the needle 110, which pivots in the center of the movement , displays the time worked during the current week. The needle 112, set at 4 o'clock, indicates the average weekly working time owed by the employee to his employer, while the needle 114, which is at 8 o'clock, shows the cumulative differences, in addition or in less, between the time of work done each week and the time due.

The box 100 carries, in addition, two pushers 116 and 118, respectively arranged at 2 o'clock, to control the start and stop counting, and 4 hours to ensure the reset.

In a similar way to the watch of figures 1 and 2 , the box 100 advantageously comprises a groove 120 in which six indexes 122 to 127 are housed, the index 122 being fixed and the indexes 123 to 127 movable.

The movement of this watch includes, in a conventional manner, but not shown in the drawing, a barrel ensuring the supply of energy, a work train that causes an escapement, which maintains a balance, which defines the running of the watch.

The mechanism specific to the control of the needles 110, 112 and 114 is represented on the figures 4 and 5 . The figure 4 shows, more particularly, the components associated with the commands given by means of the pusher 116, while the figure 5 refers to the components biased when the pusher 118 is actuated. In these figures, only moving parts are shown. It goes without saying that these are arranged on a support, for example a platen, as has been explained about the embodiment presented with reference to the figures 1 and 2 .

As shown in figure 4 , the mechanism comprises four mobiles bearing the references 128, 130, 132 and 134 on which the hour hands 104, the work time 110, the working time due 112 and the reported time 114 are respectively fixed.

The wheel 128 is driven by the finishing gear and makes a turn in twelve hours. It meshes with a central wheel 136, coaxial with the wheel 130, through an intermediate wheel 138. The central wheel 136 therefore rotates continuously. A clutch 140 provides a kinematic connection between the wheels 138 and 130. It comprises a rocker 142, pivoting E and provided with an elastic arm 142a and a boss 142b. It carries a mobile 144 formed of a wheel 144a and a pinion 144b, superimposed and arranged respectively at the same height as the wheels 136 and 130.

The rocker 142 cooperates, by its boss 142b, with a cam 146, which is driven by the pusher 116, schematically represented by an arrow, which controls a pawl 148. The cam 146 comprises, superimposed, a cross 150 with six separate arms 150a by as many rounded recesses 150b, of complementary shape to the boss 142b, and a ratchet wheel 151, comprising twelve teeth. The cross 150 is at the same level as the rocker 142, the boss 144b being supported on one of the branches or in one of the recesses. The wheel 151 furthermore cooperates with a retaining pawl, not shown in the drawing, and which prevents the cam 146 from moving back at the return of the pawl 148.

With each pressure on the pusher 116, the cam 146 rotates 30 °, the boss 142b passing from a recess to a next branch and vice versa. The rocker 142 is thus arranged so that the mobile 144 is in engagement with the wheels 130 and 136 when the boss 142b bears against one of the branches 150a, thus ensuring the clutch function, or on the contrary remote of these wheels when the boss 142b is supported in one of the recesses 150b, so that they are disengaged from one another. In other words, it suffices for the user to press on the pusher 116 to start the counting of the working time, then press again to stop it.

The adjustment of the position of the needle 112, which corresponds to the working time due, is done by means of the crown 108 and a mechanism similar to that shown in FIG. figure 2 , which was not shown in the drawing, to avoid overloading it.

The drive of the needle 112 is in the first position drawn from the crown 108, via the wheel 132. For this information to be useful, it is necessary that it can be compared with the time worked. , which ensures two toothed sectors 152 and 154 superimposed, pivoting about the same axis F and connected to each other by means of a spiral spring 155, schematically represented on the figure 5 interposed between them and fixed to each of them by its extremities.

The sector 152 is connected to the wheel 132 by a mobile 156 and carries a pin 152a forming a stop and intended to cooperate with the sector 154, the latter being brought into abutment against the pin 152a in the absence of external stress. The sector 154 is connected to the wheel 130 by two references 158 and 160 carried by a rocker 162, whose function will be specified later, pivotally mounted about an axis G which coincides with the axis of rotation of the reference 158. The flip-flop 162 has a boss 162a, which cooperates with a spring 164 which generates a torque maintaining the return 160 in engagement with the sector 154, as well as a finger 162b and a bearing surface 162c, the functions of which will be explained by reference. to the figure 5 .

At the start of the count, the needle 110 is at noon and the sector 154 resting against the pin 152a. When the user actuates the pusher 116, the clutch 140 kinematically links the wheels 130 and 136, so that the wheel 130 begins to rotate clockwise. It causes the references 158 and 160 and the sector 154 which rotates about the axis F, in the counterclockwise direction. The active length of the sector 154 is defined by the position of the pin 152a or, in other words, the needle 112.

Throughout the week, the user alternately orders the stopping and starting of the counting of the working time by means of the pusher 116. When the working time carried out exceeds the working time due, the needle 114 must be driven rotating in a clockwise direction. This training is carried out by means of a reference 166 in engagement with the wheel 134. More specifically, when the sector 154 has traveled the angle corresponding to the working time due, the reference 160 is no longer retained by the sector 154, so that the rocker 162 pivots under the effect of the spring 164 until the return 160 engages the return 166, as shown in phantom on the figure 4 . From this moment, the wheel 134 is kinematically connected to the wheel 130 and rotates clockwise, until a new pressure on the pusher 116 disengages the wheel 130.

At the end of the week, the needle 110 must be reset to zero, the difference between the time performed and the time due being counted by the needle 114. This function is performed by the components of the mechanism shown in FIG. figure 5 .

More particularly, in this figure, the wheels 130 and 134, the sector 154, the references 158, 160 and 166, the rocker 162, with its finger 162b and its bearing surface 162c, and the spring 164. The push 118 is schematically represented by an arrow. A pawl 167, formed of a rigid arm 167a and an elastic arm 167b, is pivotally mounted on the sector 154, the rigid arm 167a extending in the portion between the pivot point F and the periphery provided with the toothed portion, along the side against which the pin 152a bears. A pin 154a is attached to the sector 154, in a position adjacent to the rigid arm 167a. The sector 154 is provided with a cutout 154b in which is engaged the end of the elastic arm 167b, arranged so that it generates a torque that keeps the rigid arm bearing against the pin 154a.

The mechanism further comprises three flip-flops 168, 170 and 172, a hammer 174 and a cam 176 integral with a shaft carrying the needle 110 and frictionally mounted on the wheel 130. The rocker 168 amplifies the movement of 118. It pivots about an axis H arranged in the vicinity of 6 hours and bears against the rocker 170 halfway between the pivot point of the latter and the fulcrum of the pusher 118.

The flip-flop 170 is pivotally mounted about an axis J disposed in the vicinity of 3 hours. It comprises three control fingers 170a, 170b and 170c, arranged to cooperate respectively with the sector 154, the rocker 162 and the hammer 174, and an elastic arm 170d, bearing against the plate in the neighborhood of 1 hour and generating a torque tending to support the rockers 168 and 170 against each other.

More specifically, the end of the finger 170a is arranged so that it comes to bear against the rigid arm 167a of the pawl 167, and thus to drive the sector 154 until it is no longer in contact with the the reference 160.

The end of the finger 170b is arranged to cooperate with the bearing surface 162c and thereby pivot the rocker 162 in the counterclockwise direction, which causes the disengagement of the reference 160 from the sector 154.

The end of the finger 170c is in abutment against a side of the hammer 174, so as to move the latter so that it comes against the cam 176, thus ensuring the zeroing of the needle 110, as will be explained later .

The fingers 170a and 170b form between them a cut 170e whose function will be indicated later.

The flip-flop 172 pivots on an axis K disposed substantially at 5 o'clock, between the center of the movement and the rocker 168. It comprises an elastic arm 172a whose end is engaged in the cutout 170e so as to be driven when the flip-flop 170 pivots, a rigid arm 172b carrying a reference 178 and terminated by a finger 172c intended to cooperate with the finger 162b to retain the rocker 162.

The hammer 174 is pivotally mounted about an axis L disposed between 2 and 3 hours. It extends towards the center of the movement, in the direction of the cam 176, and is arranged so that, when the lever 170 comes to take leaning against its side, it pivots clockwise. The hammer 174 has a substantially planar work surface 174a that contacts the cam 176 and generates a torque that rotates the shaft until the needle 110 is at noon.

A spring 180, integral with the plate, acts on the hammer 174 on the opposite side to the finger 170c and generates a return torque tending to bring, in a counterclockwise movement, the hammer 174 in the rest position.

When at the end of the week, the user wants to reset the needle 110, he presses the push 118. Two situations can then occur.

In the first, which has not been illustrated, the actual working time is greater than the working time due. This means that the sector 154 is no longer driven by the return 160, which is engaged with the reference 166. When the user actuates the pusher 118, it drives the flip-flops 168, 170 and 172.

The flip-flop 172 then retains the flip-flop 162 in the position it occupies, by means of the finger 172c, while the reference 178 engages with the references 160 and 166. As the latter is also engaged with the reference 166, these three references block each other, as well as the gear train up to the wheel 130.

The finger 170a comes to bear against the arm 167a of the pawl 167. It pushes the sector 154 clockwise until the end of the finger 170a exceeds the end of the arm 167a. The sector 154 is then no longer held and it falls against the return 160. The rocker 170 continues its movement until the finger 170b comes into contact with the bearing surface 162c, which pivots the rocker 162 in clockwise and releases the sector 154, which returns to its initial position, bearing against the pin 152a.

On the other hand, the finger 170c acts on the hammer 174 which rotates the cam 176 and, with it, the shaft carrying the needle 110.

When the user releases the pusher 118, the elastic arm 170d returns the latch to its initial position and carries with it the flip-flops 168 and 172. During this movement, the pawl 167 clears to let the finger 170a.

The second situation corresponds to the case where the working time is less than the working time due. In this case, the return 160 is always engaged with the sector 154. When a pressure is applied on the pusher 118, the flip-flop 168 pivots and also drives the flip-flops 170 and 172. The flip-flop 172 causes the reference 178 to engage with the references 160 and 166, then the elastic arm 172a is deformed, maintaining the return in this position. After which, the finger 170a pushes the pawl 167, which drives the sector 154, which rotates the returns 160, 178 and 166, which causes the wheel 134 in the counterclockwise direction. This amounts to saying that the mechanism takes into account the difference between time due and time done. When the sector 154 reaches the position in which the reference 160 is no longer driven, we find the same conditions as those corresponding to the end of the first situation.

The mechanism as described in Figures 3 to 5 can advantageously be completed by such functions as locking the pusher 118 when the clutch 140 is engaged with the wheels 130 and 136, or the zeroing of the needle 114. Frictions will also be added, so that there is no inadvertent movement when the clutches are released. These functions are well known to those skilled in the art. The locking can be ensured in a manner similar to that performed between the hammer 64 and the lock 68. The zeroing of the needle 114 can easily be carried out by an additional pusher placed at 8 o'clock, controlling a hammer and a cam secured to the shaft carrying the needle 114. Here again, the shaft carrying the needle 114 is advantageously mounted frictionally on the wheel 134.

This description has been made with reference to two embodiments very different from each other, showing two ways of allowing the counting a weekly working time. It is obvious, however, that many other solutions can be envisaged without departing from the scope of the invention.

Thus, in particular, that according to an alternative embodiment not shown, it is possible to give the wearer of the watch the possibility of setting itself, a priori, the hours during which the counting means must be activated. For this purpose, for example, the cam 54 of the figure 2 can be replaced by a composite mechanical structure of form adjustable from the outside in order to modify, at will, the moments at which the clutch is controlled.
