Definitions

  • ABSTRACT A measure and control instrument for divers comprising a time counter, a bathometer, and means actuated by said time counter and bathometer for automatically and continuously indicating the duration of the decompression stage to be observed by a diver.
  • Such means comprises a mechanism driving at least one indicating member in an intermittent movement the frequency of which is constant and the amplitude of which varies with the depth of submersion.
  • the known diving equipment included a watch to measure the duration of submersion, a pressure gauge or bathometer to measure the depth of submersion, and a chart or a table to be used by the diver underwater after having taken the readings from his watch and pressure gauge or bathometer.
  • Some attempts have been made to simplify this clumsy equipment; for example, the use of watches provided with special glasses or dials having indications corresponding to the diving tables.
  • these indications are complicated to interpret or to use, especially because they often necessitate manipulations underwater which are rendered difficult for many reasons, for example the obscurity, the difficulty of carrying out certain gests, and so on.
  • the known equipment and procedure are totally unsuitable to the essential requirements of freedom of movement and safety.
  • An object of this invention which sets out to remedy this situation, is to provide a control and measuring instrument for divers comprising a time counter and a bathometer.
  • a further object of this invention is to provide such an instrument which comprises means which automatically and continuously transmit to at least one indicating member, the duration of the stage or stages of compression from data provided by the time counter and the pressure gauge or bathymeter.
  • the means in question can be mechanical, electronic or otherwise.
  • the instrument too can be entirely mechanical, partly mechanical, partly electronic, or entirely electronic.
  • These means must simply be capable of computing automatically and continuously the duration of the decompression stage or stages from inform ation transmitted by the time counter and the pressure gauge or bathometer.
  • the referred-to-means which must continuously compute the duration of the decompression stage from the measure of the time and the measure of the depth of submersion may achieve this object if they comprise a first element moving at a constant speed, a second element moving at a variable speed greater than that of the first element, a device for regulating the speed of this second element as a function of the depth .of submersion, and an indicating member showing a value which is proportional at any instant to the difference of position of the two elements. If the parameters are correctly determined, this value gives a permanent measure of the length of the decompression stage.
  • FIG. 1 is a plan view of the instrument, showing the dial side;
  • FIG. 2 is schematic plan view, similar to FIG. 1, the glass, hands, dial, and exterior control members having been removed; I
  • FIG. 3 is a cross-section taken along line III-III of FIG. 2; but with the hands, dial and glass shown;
  • FIG. 4 is a cross; e ct ion 9f a detail taken along line lV-IV ofFlG.
  • FIG. 5 is a graph showingthe duration of the decompression stage of 3 meters indicated by the instrument for a diving depth of 30 meters;
  • FIGS. 6 to 11 schematically show g u g the instrument corresponding to the diagram of FIG. 5 for submersion times of 0, 15, 30, 45, 60 and 75 minutes.
  • v I
  • the instrument shown. indicates the date, hour, minutes and seconds in the manner of a conventional watch and, during a dive, the duration of submersion, the depth of the diver and, continuously, the duration of the decompression stage to be observed at -3 meters.
  • the instrument additionally indicates at any time to the diver, while he is carrying out a decompression stage, the remaining time that he must stay at that stage.
  • the instrument can be used for successive dives.
  • the instrument shown, worn on the divers wrist comprises a monobloc watertight casing 10, a glass 11 fitted on a bezel 12 itself fixed on the bezel-snap with interpositioned joints ensuring an absolute watertightness down to a depth of at least 100 meters.
  • a mechanism 17 intended to drive, from the movement, on the one hand a graduated crown 18 and on the other hand, an indicating hand 19.
  • This crown 18 and the hand 19 constitute the two elements mentioned above.
  • an hour dial 20 and an annular dial 21 carrying a graduation 0 through 60 are located at the level of the crown 18, respectively positioned at the center and at the exterior thereof. These two dials are fixed; the first rests on the plate 16 and the second is pinched between the bezel and the bezel-snap of the casing.
  • dial 20 turn three hands, hour hand 22, minute hand 23, and second hand 24, driven in a conventional manner by the watch movement through ndicati ons of plates 16 and 17.
  • Hand 19 is mounted on a fourth bush 25, exterior to and coaxial with the three others.
  • the turning crown 18 is divided into a quarter-tum sector 26 colored white,” and three-quarter turn sector '27 colored red. This second sector is graduated 0 through 45 minutes and has an index 30 indicating on the dial 21 the submersion time in minutes; reference numeral 29 designates the winding crown which also serves for setting the hour and date of the watch. 4
  • Crown 18 is intended to be driven at a rate of 1 revolution per 60 minutes by the watch movement through the intermediary of a pinion 39, a runner 41 pivoted between plates 15 and 16 and a toothed wheel 43 which meshes with an interior toothing of the crown 18.
  • the bottom 32 of the casing which has openings 33 and an aneroid membrane 31 welded on a ledge of this bottom, defines a chamber 34 in which water can enter.
  • the deformations undergone by this membrane under the action of the water pressure are transmitted to a needle 35 through a lever 36, a rack 37 and a pinion 38 freely turning on a runner .58 pivoted between the plates 15 and 16.
  • the link between the pinion 38 and the needle 35 is through a pinion 60 secured to a fifth bush 61 positioned between the bush upon which is secured the hour hand 22 and the bush upon which is secured the indicating hand 19.
  • An arm 50 at the end of which is mounted a finger 49 provided with a ball, is solid in rotation with the pinion 38. Consequently this finger is angularly displaced in the clockwise direction upon increase in the pressure on the membrane and in the opposite direction upon decrease of this pressure. Arm 50 is positionned approximately at 12 oclock when the instrument is only submitted to atmospheric pressure, and approximately at 3 oclock when the pressure on the membrane reaches 7 atmospheres (60 meters).
  • finger 49 The precise role of finger 49 will be explained in detail farther on.
  • the assembly formed by the membrane 31, lever 36, rack 37, pinion 38 and hand 35 constitutes a bathometer the depth indications of which are given by needle 35 and dial 21.
  • a shock-absorber 54 mounted on the bottom of the movement absorbs the deformations of the membrane caused by movements of the diver.
  • dial 21 cooperates not only with index 30 to indicate the time of submersion, but also with hand 35 to indicate the pressure, or correctly speaking, the depth; the 0 through 60 graduation is thus read in minutesor in meters, depending whether index 30 or hand 35 is under consideration.
  • Hand 19 is normally caused to rotate by the watch movement through pinion 39, two toothed wheels 28 and 40 both belonging to the runner 41 and by a crank-shaft comprising a toothed wheel 42 pivoted in plate 16 (FIG. 4).
  • a rod 44 carrying at its end a click 45 intended to cooperate with a ratchet wheel 46.
  • the click 45 and wheel 46 form a clickand ratchet wheel of which the stop click is indicated by reference numeral 47.
  • Wheel 46 is keyed on the previously-mentioned runner 58 and its displacements are transmitted by a toothed wheel 57 of this runner to a toothed wheel 56 solid with a bush 25 and by this bush to hand 19.
  • Rod 44 is submitted to the action of a spring blade 48 which tends to urge the click 45 against the ratched wheel 46.
  • the end of rod 44 located at the level of finger 49 abuts against this latter for a certain time during its movement before the click 45 can actuate wheel 46.
  • the angular position of finger 49 is capable of varying about 90 between the two above-mentioned extreme positions, and it is seen that the first tooth with which the click meshes upon the driving alternation of the rod thus varies according to the angular position of arm 50. It follows that the angular displacement imposed to the ratchet wheel 46 and consequently to the hand 19, upon each rotation of the wheel 42, corresponds to a variable number of teeth of the ratchet wheel.
  • finger 49 when the pressure reaches and exceeds 5 atmospheres (40 meters), finger 49 is completely retracted, i.e. it does not obstruct the movement of the rod and the displacement of the ratchet wheel is maximum. In the second of the above-considered extreme positions, finger 49 permanently maintains the rod and the click away from the ratchet wheel.
  • the number of teeth of the wheel 46, the dimensions and speeds of the various members of the mechanism, and the shape of the rod are determined in a manner such that this latter situation is maintained until the angular position of the arm 50 corresponds to a depth of 16 meters inclusive. Only from a depth of 18 meters does the click 45 come into engagement with the wheel 46 and cause an angular displacement which regularly increases each time that the depth increases by 2 meters, from 18 meters down to 40 meters.
  • the starting and the resetting to zero of the disk 18 and hand 19 are controlled simultaneously by the pushpiece 52.
  • the mechanisms used for this purpose well known to watch makers, have not been shown.
  • the knurled crown 53 enables the needle to be started from an arbitrarily chosen angular position. The importance of this feature will appear further on.
  • the graph of FIG. 5 shows readings taken with the described instrument for a dive carried out to a depth of 30 meters and a duration of submersion from 0 to 75 minutes. These readings are compared with the corresponding values shown in tables, in this case by the GERS table (blacked in coordinates) and the SEEMANN table (circular coordinates).
  • FIGS. 6 to 11 are shown the positions respectively occupied by the dial l8 and hand 19 of the described instrument for durations of submersion equal to 0, 15, 30, 45, 60 and 75 minutes. The good agreement between the readings of the instrument and the tabular values will be noted. The small divergences noted fall within the safety margin for the instrument.
  • the maximum submersion time without a decompression stage for a depth of 30 meters given by the instrument is 19 minutes, whilst the GERS table gives 20 minutes.
  • the instrument indicates a decompression stage of 33 minutes, the SEEMANN table 30 minutes and the GERS table 37 minutes.
  • the instrument indicates 45 minutes, the GERS table 46 minutes.
  • the use of the instrument is extremely simple; at the moment of diving, the wearer presses the chronometric push-piece 52 once to set the index 30 and hand 19 at zero (i.e. at 12 oclock), and again to start the disk 18 and hand 19 which, at that moment, is driven by the finger 55. Whilst the diver is at or below the 16 meter limit, the crank-shaft mechanism turns but is inoperative, as has been previously explained, because the position of the finger 49 prevents the click 45 from reaching the teeth of the ratchet wheel; on the contrary, the hand 19 turns with the crown 18 at a rate of 1 revolution per 60 minutes.
  • the finger 49 At the depth of 18 meters the finger 49 reaches an angular position such that the click 45 can engage the wheel 46 and advance it eight teeth by alternating movement; the hand 19 thus turns faster than the dial 18 and penetrates in the white zone of the crown; if the diver continues to descend the finger 49 retracts more and more and the click 45 can engage increasingly earlier with the ratchet wheel; this results in a regular increase in the angular speed of the hand 19 of 1/60 revolution per hour each time that the diver descends 2 more meters.
  • the diver stops at a depth of 30 meters to carry out observations or any work whatsoever.
  • the angular speed of the hand 19 remains constant, greater than that of the dial 18; as long as the hand 19 is in the white zone 26, the diver knows that it is not necessary to carry out a decompression stage. From the moment when this hand penetrates in the red zone, he knows that he must carry out a decompression stage the duration of which is indicated at any moment by the position of the hand 19 facing the graduation carried by the red zone 37. Additionally, the index 30 read on dial 18 also gives him at any moment his submersion time. Finally, his depth is indicated on the same dial 18 by needle 35.
  • the value of the C-factor can be calculated from tables according therfialculat d increase.
  • e data rom the above-mentionned table can add tionally be carried by a bezel, possibly turning, on the instrument casing so that the diver does not need to consult separate tables.
  • the invention is not limited to the embodiment which has been described and shown by way of example.
  • a measure and control instrument'for use by divers comprising a time counter for measuring the time of submersion, a bathometer for measuring the depth of submersion, and means actuated by said time counter and said bathometer for determining and indicating the duration of the decompression stage to be observed by a diver in function of the time and depth of submersion, said means comprising a mechanism driving at least one indicating member in an intermittent movement the frequency of which is constant and the amplitude of which varies with the depth of submersion.
