Definitions

  • Two or more electrodes are arranged to constitute a mechanical oscillating or swinging arrangement of which at least one electrode is resiliently supported and is capable of flexing and swinging along a predetermined length of an oscillating course and direction toward and away from the other electrode or electrodes; a charge compensation in condenser fashion occurring when selected ones of said electrodes approach each other closely enough, within an electric field established between said electrodes.
  • said electrodes are sufficiently remote or spaced from each other, but are aligned with their frontal faces confronting each other.
  • the invention is applicable more generally to the operation and performance of clocks, watches and similar instruments requiring substantially no surveillance and nevertheless acting dependently and accurately for an extensive length of time.
  • Yet a further object of the invention is directed to means affording convenient and continuous replacement or replenishment of energy losses to which said device or instrumentality is being subjected during operation.
  • FIG. 1 shows a basic diagram of a device according to the invention employing two electrodes, one of which can be excited to perform mechanical vibrations.
  • FIG. 2 is another form or embodiment pursuant to the invention with two electrodes, both of which being excitable to carry out vibrations.
  • FIG. 3 is a similar embodiment equipped with three electrodes, two of which being movable.
  • FIG. 4 is still another form of the invention having incorporated three electrodes, of which only one is movable.
  • FIG. 5 shows schematically the application of the embodiment of FIG. 4 to a ratchet wheel drive.
  • a mass For achieving a structure capable of performing desired 7 vibrations a mass must be mounted in a resilient or springy manner and in a fashion that the mass can transmit its kinetic energy to a resiliently suspended or supported member, and after complete transmission or transfer of kinetic energy of the mass, the static energy stored in the resiliently suspended member is again completely transferred to the mass in the form of kinetic energy. To maintain the resultant vibration, it becomes further necessary to replace any inevitably resulting energy losses.
  • FIG. 1 there is disclosed a device with an arrangement capable of executing vibratory motions for the drive of a clock or timepiece mechanism.
  • an electrode 2 On an elastic or resilient member or tongue 1 is fastened an electrode 2, which constitutes at the same time primarily the vibrating mass.
  • the other end of the tongue I is rigidly connected with an insulating block 3.
  • the electrode can swing back and forth in the direction of arrow 4, when it is excited or caused to do so.
  • a second electrode 5 is provided at a distance and location opposite the movable electrode 2, which is likewise fastened on said block 3 by means of a relatively heavier support or carrier 6.
  • Tongue I and carrier 6 are electric conductors, so that through connections 7 and 8 electric current can be supplied to the electrodes from a voltage source or energy cell (not shown) for the charging of these electrodes.
  • Block 3 contains or consists of insulation material.
  • the two opposite electrodes 2 and 5 constitute or function as a condenser, the capacity of which depends on the size of the mutually opposite faces of the electrodes and the distance between them.
  • This condenser charges across the connections 7 and 8, so that electrode 5 has a positive and electrode 2 a negative potential.
  • electrode 5 By the action of the electric field between these two electrodes the latter are pulled and attracted toward each other, the movable electrode 2 being moved counter to the force of the elastic tongue 1 toward and up to electrode 5.
  • Electrode 2 is now exposed only to the action or force of the tensioned elastic tongue member 1 and hence can swing back, passing, owing to inertia, beyond its neutral or initial position to a second end position shown in broken lines (FIG. I).
  • the voltage source with which the electrodes are connected is high-ohmic, or has purposely been rendered high-ohmic by a preconnected or series ohmic resistance (not shown), in order that at the time of contact of the electrodes the short circuit current is limited and, on the other hand, the condenser constituted by the electrodes, after these latter two do no longer touch each other due to the return movement of the movable electrode, is charged again with delay.
  • This internal resistance is so great that the condenser is charged to practically the full voltage of the energy supply source at the earliest after attainment of the central position of electrode 2.
  • FIG. 2 another form of construction according to the invention is revealed in principle. It differs from the first embodiment only in the likewise resilient arrangement of the second electrode 5, which is fastened to an elastic tongue 1', so that the two electrodes 2 and 5 are able to execute mutually oppositely directed swinging movements, whereby they touch once in the course of each occurrence of vibration for the purpose of charge exchange, as is indicated in broken lines. Also these electrodes are connectable to a high-ohmic voltage or like energy source (not shown).
  • two electrodes 10 and l l maintained at a distance by a web or bridge element 9, and electrically insulated from each other, are arranged at the freely vibrating end of a resilient tongue 12. These electrodes are connected for electric conduction via flexible conductors l3 and 14 with the terminals l5, 16 so that corresponding charges can be supplied to them from an energy cell or source (not shown).
  • a stationary or fixed third electrode 17 which is electrically insulated.
  • the latter assumes the same polarity, and subsequently electrode 10 is repelled from and simultaneously electrode 11 is attracted by electrode I7, because the latter two carry opposite charges.
  • FIG. 4 shows a variant of the embodiment of the invention of FIG. 3, in that the two outer electrodes 18 and 19 are fixedly attached or held in position and the central electrode 20 is fastened to the freely vibrating end of tongue 21 as indicated in FIG. 4 at 25, 26. Electrode 20. is electrically insulated from the remaining part 7 of the instrumentality, as shown.
  • the operation of this structure of FIG. 4 is basically the same as that of FIG. 3 with the exception that the central electrode 20 is able to swing back and forth between the two outer electrodes l8 and 19. (See wiring diagram of FIG. 5.)
  • Contact points 22, 23 and 2A of a known conductive metal or material resistant to burning down or melting are arranged on the end faces of the respective electrodes. They render it possible that when using a voltage source of 1,000 volts, for
  • the electrodes need not approach each other completely for the charge exchange or load compensation, in that already at a sufficiently minute or small distance between the contact points a spark arcs over, which suffices for charge compensation. In this way the harmonic vibratory movement of the mass (electrodes) is not disturbed by any impact of the electrodes on each other.
  • a transducer may be inserted in the circuit, which transforms the current surges occurring during a charge reversal into an alternating current voltage, which can be tapped at the terminals of the secondary winding of the transformer or transducer, At
  • the resilient tongue a pawl may be arranged which engages in the asymmetrical teeth of a gear, the latter being advanced by one tooth during each vibratory movement. (See FIG. 5.)
  • an isotropic generator is advantageously employed.
  • Such voltage cells or sources can be accommodated within a minimum of space and yet furnish a terminal voltage of more than 1,000 volts.
  • a system for generating periodical mechanical oscillations with relatively high-frequency stability in particular for use in connection with timepieces and like instruments, characterized by two electrodes springedly and swingably supported and mutually electrically insulated, a common bridge element for said two electrodes forming the support therefore and maintaining the two electrodes at predetermined fixed distance from each other, a third electrode having opposed power source.
