Definitions

  • This invention relates to new andiuseful improvements in torsion pendulum clocks.
  • the object of the invention is to provide a torsion pendulum clock of the above description eliminating the mentioned disadvantages and having a simple design which ensures both simple assembly and does not depend on the design features of other clocks with a torsion pendulum.
  • the torsion pendulum is mounted on a pin protruding out of the actuator.
  • the actuator may be a known electronically or contact controlledmovement serving merely to propel the pendulum.
  • Another feature of the invention consists in providing ported in the housing only by two points which may be.
  • the actuating unit with the pin is provided with permanent magnet discs between .which the electrical coils are placed.
  • Such an electrical drive is very simple and has a capacity favorable and entirely adequate for actuating the torsion pendulum.
  • An additional advantage is that the pin is actuated by a helical spring. Apart from the helical spring, the whole pendulum actuator has virtually only one moving part, viz. the pin itself with the discs and permanent magnets mounted thereon. No other'moving parts are needed.
  • means can be provided to operate the clockwork andthe torsion pendulum actuator by the same electric supply. This precludes stoppage of the clockwork while the pendulum continues to rotate. Therefore when the torsion pendulum is seen to oscillate, it
  • FIG. 2 i s'a sid'e'vi'eiw partly in section similar to FIG. l but taken across only the torsion pendulum with its FIG. 3 isa' s'ec'tion'vie'w across the actuator in FIG. 2
  • the torsion pendulum 16 is mounted under the clock and is operated by an actuator 3 in the base 23.
  • the actuator is entirely operably independent from the clockwork. Details of the actuator 3 are shown generally in FIG. 3.
  • the torsion pendulum 16 is, according to the invention, mounted on a pin 6 which extends upwardly from the pendulum actuator 3.
  • tapered coupling element 10 is fitted on pin 6 on which i the torsion pendulum is set with a matching bore.
  • actuator 3 is mounted in the clock base 23 by means of a central fixing screw 2 and a cap nut 12. This serves to mount and adjust the actuator separate from the clockwork using only the central fixing screw 2 and nut 12.
  • FIG. 3 The central actuating pin 6 is only supported at two points, namely, at its bottom with a journaled engagement on a support 4 and at an upper guided engagement 16a in fixing screw 2.
  • two holes 24 and 25 are provided on opposite sides of screw 2 through which a disc 17 can be seen.
  • Disc 17 and a second disc 18 spaced therefrom are fixed to pin 6 and are provided with permanent magnets 14, 15, and 5.
  • Magnet 5 serves also as a spacer between both discs 17 and 18.
  • Two propulsion coils 7, 11 for the rotor and both discs are fixed to the housing 1 between the discs 17 and 18, the rotor thus being fixed to pin 6.
  • a helical spring 8 is provided under disc 18 a helical spring 8 is provided connected by a suitable fixture with pin 6. The spring develops the return force for the torsion pendulum after each swing.
  • the electrical coils 7 and 11 are connected to a battery circuit or other source of current which also supplies the clockwork.
  • a bottom lid 9 is fixed from below by two screws 21, 22 to the housing 1 and carries the already mentioned support 4.
  • the functioning of clockworks to run the time piece but not the torsion pendulum is basically known.
  • the invention has inter alia the advantage that, as clearly seen in FIG. 1, the whole pendulum actuator 3 is easily mounted in the base 23 of the clock and entirely independent from other assemblies.
  • Another advantage of the invention is that existing clocks can be provided with additional actuators 3 and a torsion pendulum.
  • a torsion pendulum clock comprising a. a base portion,
  • the torsion pendulum clock of claim 2 including a d. drive means in said housing driving said pin rotatcouplmg element mounted on p l end of ably in alternate directions in a torsion pendulum 5 said pin and having a tapered outer surface engageable movement, by said pendulum.
