Definitions

  • the object of the present invention is to provide a driving device which is capable of driving one or more bells mounted in a tower bell tower, whether it be a church tower or another building, which does not have the aforementioned drawbacks.
  • the device according to the invention has the additional advantage of additionally offering increased security, and this in an unexpected manner.
  • the object of the present is a device for driving an oscillating shaft, in particular a shaft connected by a transmission to the oscillating support of a bell, characterized by a pneumatic cylinder with a piston movable in a cylinder, by a rack fixed to the piston, by a motor shaft driven by the rack and driving the said oscillating shaft, and by a fully pneumatic control circuit which comprises, on the one hand, a maximum pressure detector capable of reacting to the pressure in a chamber of the cylinder and, on the other hand, a motion reversal detector capable of reacting to reversals of rotation of the oscillating shaft.
  • Fig. 1 shows, in general, the location of the device.
  • a bell 1 is suspended from an oscillating support 2 which is capable of oscillating around an axis materialized by two journals designated by 3 and resting on bearings.
  • the oscillating support 2 is integral with a toothed wheel 4, on which passes a chain 5 which passes, on the other hand, on a pulley 6 (fig. 1 and 2).
  • the pulley 6 is integral with an oscillating mobile 7, which constitutes a clutch plate and which is supported by means of bearings 8 on a motor shaft 9. This motor shaft is itself supported by different bearings 10, by relative to a frame 11.
  • a part of this frame 11 constitutes a fixed clutch cylinder 12, in which is mounted a movable clutch plate 13 which is keyed onto the shaft 9 but axially movable on this shaft.
  • a pneumatic pressure, acting inside the cylinder 12 and urging the plate 13 to the right, makes it possible to temporarily couple the shaft 9 to the plate 7 and, consequently, to drive the latter in rotation.
  • An opposing spring 14 ensures the return of the clutch plate 13 to the triggered position in the absence of air pressure in the left end of the cylinder 12.
  • the shaft 9 is driven in an oscillating rotary movement, by means of a drive pinion 15 which is driven out on the left end of the shaft 9 and of a rack 16.
  • This rack 16 is also visible, as is the pinion 15, in FIG. 3.
  • the rack 16 is integral with a double piston 17a, 17b, which slides in a cylinder 18 forming at its two ends two chambers 18a and 18b, which can be supplied alternately with pressurized air.
  • the movement of the rack 16, from one end of its travel to the other, causes a rotation pinion 15 at an angle of 1080 °. If the coupling 7, 13 is kept in the engaged state during this movement, the chain pulley 6 will perform the same angle of rotation and the wheel 4, driven by the chain 5, will perform a movement of a lower amplitude, for example with a total amplitude of the order of 300 °.
  • Fig. 3 also schematically shows the control circuit of the device described, a control circuit which is generally represented by the number 19.
  • this circuit essentially comprises a key valve 20 and a time relay 21.
  • the circuit 19 further comprises various detectors.
  • the detector 22 is a valve controlled by a pusher.
  • This pusher is already shown diagrammatically in FIG. 1 opposite the periphery of the wheel 4, in a predetermined position, so as to be actuated by a cam boss 23, fixed on the wheel 4, the actuation of the detector 22 taking place when the amplitude of the movement of bell 1 reaches a predetermined limit value.
  • this limit value can be set at will by placing the push-button valve 22 at the desired location, opposite the periphery of the wheel 4.
  • the control circuit further comprises two pressure detectors, of the pressure switch type, designated by 23 and 24.
  • adjustable pressure switches will be used so as to emit a control signal when the pressure to which they are subjected reaches a predetermined value. between 2 and 8 bars.
  • the pressure switch 23 will, for example, be adjusted so as to act for a pressure P1 equal to 5 bars while the pressure switch 24 will be adjusted so as to act for a pressure P2 lower than P1 determined from case to case according to the mass to be moved.
  • the control circuit 19 comprises a fourth detector constituted by a leakage sensor 25, connected to a corresponding relay 26.
  • the leakage sensor 25 which operates like a proximity detector cooperates with a witness plate 27.
  • This witness plate formed of two parts, of rectangular shape, with a notched internal edge, is mounted, as can be seen in FIG. 2, on the oscillating mobile 7.
  • the two halves of the plate 24 are screwed together, with a slight tightening (obtained by springs), on a circular surface 28 of the support 7.
  • the sensor 25 is placed opposite a straight edge of the plate 27, in the vicinity of one of its ends. During the oscillation of the rotary assembly 6, 7, this plate 27 bears against the sensor nozzle 25.
  • the control circuit further comprises various valves, five in number, which perform the following functions.
  • the valve 30 is an inlet valve.
  • the key valve 20 When the key valve 20 is engaged, it is actuated, so that the pressure coming from the source 29 reaches various elements of the circuit, in particular the preselection valve 31.
  • This inlet pressure which is measured by a pressure gauge P1, and which will be called the pressure P1 hereinafter, is adjusted by means of the adjustable limiting element 32.
  • the pressure P1 passes through it and reaches up to the next valve 33 which is the control valve of the two chambers 18a and 18b of the cylinder 18.
  • This pressure will be designated by the indication P2.
  • the valve 33 is controlled by auxiliary pressures on its right end (A1) or its left end (Ao) and directs the inlet pressure P, or P2 to the chamber 18a or to the chamber 18b. It therefore directly actuates the rotary actuator (17a, 17b, 15).
  • the valve 35 is intended to preselect a third pressure P3 adjusted by means of a limiter 36 and to direct on a control valve 37 directly mounted in the line supplying the cylinder 12 of the clutch, either the pressure P1 or the pressure P3 .
  • This valve 35 is controlled by the operation of the timer 21 when the key valve 20 is in the rest position. It acts upon the activation of the third phase of operation of the bell, as will be seen below.
  • the valve 37 directly controls, as said above, the clutch cylinder 12. It is controlled by an auxiliary pressure which acts differently depending on which operating phase one is in.
  • control circuit further comprises various memory relays, numbered 41 to 44, an AND cell 45, a single pulse generator 46 which, in the particular case, is adjustable with a time delay which can be chosen at will between 0.1 and 30 sec, OR cells numbered 47, 48 and 49 and a NON cell 50.
  • This cycle is started by actuation of the key valve 20 which is moved from bottom to top in FIG. 3.
  • the pressure P1 arrives in particular on the memory relay 41, so that the inlet valve 30 is actuated.
  • the pressure P1 passes through the valve 31 and arrives, after actuation of the valve 33, on the right end of the cylinder 18, that is to say in the chamber 18b.
  • the double piston 17 therefore undergoes increasing pressure going in its direction from right to left.
  • the pressure P1 reaches the cylinder 12 and the clutch is engaged.
  • the bell therefore undergoes, through the transmission 5, 6 and the shaft 9, a torque which tends to cause it to oscillate.
  • the air pressure in the chamber 18b is adjusted so as to ensure the oscillating phenomenon which starts the bell during the start-up phase.
  • the memory relays 43 and 44 are actuated so that the control of the valve 33 is switched. Pilot pressure is supplied to the left inlet Ao.
  • the clutch remains engaged, all of the oscillating masses undergo a braking torque which is applied until the direction of oscillation is reversed.
  • the detector 25 comes into action and acts on the relay 26 so that the memory relay 44 is again controlled.
  • the control pressure is again directed towards the chamber 18b, which gives the bell a torque in the other direction until the maximum pressure, detected by the sensor 24, is reached, and so on.
  • the bell therefore performs a forced oscillation, the clutch being permanently coupled, which ensures the starting of the bell.
  • the second phase is engaged, as said above, when the amplitude of the movement of the bell is such that the cam 23 (fig. 1) reaches the pusher of the push valve 22.
  • the memory relay 42 switches and the pressure threshold will, in the future, be detected by the pressure switch 23 and no longer by the pressure switch 24.
  • the control of the valve 31 acts in such a way that it is the pressure P2 which will supply the control valve 33 and no longer pressure P1.
  • the switching of the memory 42 cuts the power supply to the cell ET45, the pulse generator 46 is out of service; therefore, the distributors 33 and 37 work in parallel, so the clutch is bonded only when the chamber 18b is under pressure.
  • the operation will therefore be as follows: Upon detection of a reversal by the sensor 25, the bell is in a position where the amplitude of its deviation from the vertical position is maximum. The circuit then causes the clutch to engage and switches the control pressure on the opposite end of the cylinder 18. The moving masses are therefore subjected to an acceleration torque and receive a driving pulse. The pressure inside the driving chamber of the cylinder increases. When the threshold, determined by the pressure switch 23, is reached, the clutch is triggered so that the moving masses, integral with the bell, are released. In The double piston therefore returns, at the end of its travel, to its initial position, on the right. The bell swings freely, then returns back, which causes the nozzle 25 to close. When the rotation of the bell support shaft reverses next, the nozzle 25 opens again, which again causes the cycle described, that is to say the engagement of the clutch and the switching of the pressure from one end to the other of the cylinder of the jack.
  • the third phase of operation is initiated by the return of the key valve 20 in the position shown in FIG. 3.
  • the time relay 21 however maintains certain circuits under pressure, in particular those which control the piloting of the valve 35.
  • the NO cell 50 places the logic circuit, in such a way that the valve 37 remains permanently engaged, and the pressure P3 acts permanently on the clutch 12.
  • the valve 33 is controlled at A1, so that the chamber 18b of the cylinder of the rotary actuator is kept under pressure.
  • the double piston 17a, 17b is held in a fixed position and the clutch 12 operates as a brake, the bell oscillating under the effect of its inertia and against the braking action exerted by the plate 13 which remains practically stationary.
  • a fully pneumatic control circuit has thus been described, which makes it possible to perform all the functions which simulate a manually-controlled bell ringing. It was found that this device still had the following advantage: As an air duct connecting the compressor, placed at the foot of the bell tower, to the device located at the top of the latter, near the bell, is sufficient , if necessary, serve as an emergency water pipe (dry column), therefore, be used by fire departments in the event of an emergency. Thus, not only does the absence of electrical voltage at the top of the steeple reduce the risk of fire by short circuit, lightning strikes, or other, but moreover the presence of a pipe promotes the intervention of the emergency services in the event of of fire.
  • control circuit of the installation described could also be designed differently, with elements arranged differently or with other elements.
  • the above description shows that it is possible, by means of a simple diagram like that which is represented in FIG. 3, to carry out the functions described and to control them in a perfectly reliable manner.
  • the control of the rocking movement involves in particular an adjustment of the flow rates which are a function of the volumes of the various pneumatic elements, as well as the masses and moments of inertia of the members to be set in motion. These values will be determined during the construction of the device, from case to case.
  • the device can also be produced under multiple form, allowing to simultaneously control several different bells from the same pneumatic source.
