Definitions

  • the automatic winding mechanism is actuated by a rockable weight provided in the casing of the watch.
  • This displacements of this rockable weight are, however, generally insulficient in the smooth-running cars.
  • the advantage of this construction depends on the fact that the first casing containing all the common parts of a watch except the power mechanism, may be easily set at a place of the vehicle which is believed to be the most suitable, without taking too much space.
  • the power mechanism and the automatic winding mechanism may have the desired sizes and be provided at a place where sufiicient space is at disposal. They may already be planned with the vehicle itself and be mounted therewith.
  • Still another object of the invention is to fix said second casing to the frame of the vehicle anywhere under the engine bonnet whereby the winding of the watch is ensured by the displacements of an inertia block.
  • Fig. 1 schematically shows the general arrangement of the parts of the watch in the motor vehicle, in the first embodiment
  • Fig. 2 is a sectional view of the automatic windingand power-mechanisms of the watch
  • Fig. 3 is a view of Fig. 2 in the direction of arrow Ill;
  • Fig. 4 is a sectional view of the part of the watch fixed to the instrument-board of the vehicle;
  • Fig. 5 is a plan view of the parts shown in Fig. 4;
  • Fig. 6 schematically shows the disposition in the car of the different parts of the Watch, in the second embodiment
  • Fig. 7 is plan view of the automatic windingand power-mechanisms of the watch in this second enibodimerit;
  • Fig. 8 is a view of Fig. 7 in the direction of arrow Jill, with certain parts in section;
  • Fig. 9 schematically shows the disposition in the car of the different parts of the watch, in the third embodimerit.
  • Fig. 10 is a partially sectional side view of the automatic winding and power-mechanisms of the watch and Fig. ll is a view of Fig. 10 in the direction of arrow Xi.
  • a first casing 1 containing the train of gear wheels, the escapement mechanism and the time indicating device of the Watch is fixed on the instrument board 2 of a motor vehicle.
  • a second casing 3 containing the automatic windingand power-mechanisms of the watch is fixed on the tube 4 surrounding the shaft of the steering wheel of the vehicle.
  • An element of the casing 3 driven by said power mechanism is mechanically connected by a Bowden wire 6 to the first gear wheel of the train contained in casing 1.
  • Figs. 2 and 3 show in detail the parts contained in casing 3 fixed on the tube 4 surrounding the shaft 7 of the steering wheel.
  • Two plates 3 are rigidly fixed to the easing 3 in any appropriate manner not shown.
  • Three axles 9, 10, 11 are journalled in said plates.
  • a pinion 12 is fixed on the axle 9 which is formed with a square 33;
  • a ratchet wheel 1-3 provided with a central opening the form of which corresponds to that of the square 13, is rigidly linked to the axle 9 by a screw 15.
  • the wheel 14 is formed in one piece with a bearing surface 16 round which a pulley l? freely rotates.
  • the pulley 1'7 carries a pawl iii which co-acts with the ratchet Wheel 14 under the action of a spring 19, so that the ratchet wheel is driven with the pulley 17 when the latter rotates clockwise in Fig. 3, whereas the pulley 17 freely rotates on the bearing, surface 16 of the ratchet wheel 14- when it is driven in the other direction by a coil spring 2% wound round the shaft 7 of the steering wheel of the car and the pulley 17 and passing through an aperture 21 provided in the tube 4.
  • the pinion 12 meshes with the ratchet Wheel 22 fixed on the axle 10 constituting the arbor of the barrel 23.
  • the main spring of the watch (not shown) is as usual located Within the barrel.
  • the toothing of the latter meshes with a pinion 24 fixed on the axle 11 which is formed with a square 25 on which is adjusted a sleeve 3 26 rigidly fixed to the Bowden wire 6 which rotates in a sheath 27.
  • a brake block 28 bears against the toothing of the ratchet wheel 22 under the action of a spring 29, in order to prevent this ratchet wheel from rotating clockwise in Fig. 3 under the action of the main spring of the Watch.
  • the pulley 17 When the steering wheel of the vehicle is moved in any direction, the pulley 17 follows its movements. If this pulley rotates counterclockwise in Fig. 3, the pawl 18 simply jumps over the teeth of the ratchet wheel 14, While if the pulley 17 rotates clockwise, the pawl 18 drives the ratchet wheel 14 in the same direction. The latter drives in turn the barrel arbor by means of the pinion 12 and the ratchet wheel 22.
  • These parts comprise the train of gear wheels, that is, firstly, an intermediate wheel 38, as commonly provided in watches intended for running eight days without being rewound.
  • the Wheel 38 is riveted on an axle 31 formed with a square 32 on which is adjusteda sleeve 33 rigidly fixed to the Bowden wire 6.
  • the wheel 39 meshes with the pinion 34 of the second wheel 35 driving in turn a third wheel 36, a fourth wheel 37 and an escapement wheel 38.
  • the latter as usual drives the escapement mechanism of the watch, constituted by a balance wheel 39 with a hair spring 48, by means of a lever which is not shown.
  • the intermediate, second, third and fourth wheels consituting the train of gear wheels of the watch are pivoted in a plate 11 fixed to the casing 1 and a bridge 42. fixed to the plate 41 by means of pillars .3.
  • a pinion 44 is pressed on the axle of the second wheel 35 and located between the plate 41 and the dial 45.
  • This pinion as usual drives a minute-setting wheel 46 and an hour wheel 47.
  • the minute-hand 48 and the hour-hand 49 are fixed on the axle of the second wheel 35 and the hour-wheel 47 respectively.
  • the setting of the hands is as usual ensured by a knurled button 97.
  • the pulley 17 andthe coil-spring are so provided that the spring 20 slides in the groove of the pulley 17 as soon as the main spring of the watch is sufiiciently wound.
  • the groove of the pulley 17 is polished and the spring 28 is twice wound round the shaft 7 in order to avoid a sliding of said spring on the shaft at an inopportune moment.
  • the tension of the coil spring 20 may be regulated for ensuring the desired sliding in the groove of the pulley 17 by cutting it at the desired length and by forming a hook 99 and an eyelet 100 at both its extremities to link them up with one another.
  • a first casing 1 identical with that described in the first embodiment, is first on the instrument board 2 of the motor vehicle.
  • a second casing 50 is fixed on the motor 51 of the car above the valve-operating camshaft 52.
  • Three axles 54, 55 and 56 are journalled in two plates 53 (Fig. 8), fixed to the casing 50.
  • a ratchet wheel 57 is riveted onto the axle 54 and a pawl 58 supported by a lever 59 co-acts with this ratchet wheel.
  • Said lever is pivoted round an axle 60 and a coil spring 61 leaning against a stop 62 fixed on one of the plates 53 normally pushes the lever 59 downwards in Fig. 7.
  • a shank 63 sliding within a cylindrical tubular projection-64 of the casing 50 ' may push the lever 59 upwards under the action of a cam 65 fixed onto the camshaft 52.
  • the shank 63 andthellever 59i occupy their upper position
  • the winding of the main spring of the watch is indirectly ensured by means of the spring 61.
  • the tension of the spring 61 may be previously regulated in the appropriate manner.
  • the spring 61 can no longer push the lever- 59-and the shank 63 downwards, and the cam 65 now rotates without any function on the described-mechanism, until the. watch-has run a certain period and the mainspring, isysufiiciently-slackened so and 6, is fixed, onathe instrument board 2 of they automobile.
  • a pinion79 is rigidly fixed onto the axle 76;formed;with a'square .80, on which is fixed a ratchet wheel 81 formed in one piece with a bearingsurface 82 around which a pulley '83 freely rotates.
  • A- thread 84' is fixed'to the pulley 85 by one of its extremities and-it carries aninertia block 86 at its other end; For keepingttheblock 86 in balance against.
  • a spiral spring 98' is fixed by its internal end to a pin 87 fixed in one of .the plates 75 and by its external end to a pin 88 Med in the pulley 83.
  • a pawl 89 pivoted around. an axle fixed to the:pulley 83 co-acts with the ratchet wheel 81 under the action of a spring 90.

  • This casing could then contain a diaphragm whereby the space to one side of this diaphragm would be in communication with the atmosphere and the space to the other side of the diaphragm would be connected to the gas-mixing or vaporizing chamber.
  • Such diaphragm would thus move according to the variations of the intake pressures within the said gas-mixing or vaporizing chamber.
