Pendulum clock mechanism

Uses only two C cell batteries and is very strong. However, since anchor 16 is itself installed in a misaligned or inclined position when the clock mechanism is improperly installed, the proper reciprocating motion of pendulum bob 30 with respect to the gravitational vertical will attempt to exert a greater torque upon anchor 16 during one excursion of this oscillation as compared to the opposing excursion. This time and pendulum quartz clock … Should anchor 16, for any reason oscillate around a position offset from the designed equilibrium position, pallet pins 18 and 20 will execute different motions with respect to escape wheel 10 and will not symmetrically engage escape teeth 10a.

The ticks or "beats" should be at precisely equally spaced intervals to give a sound of, "tick...tock...tick...tock"; if they are not, and have the sound "tick-tock...tick-tock..." the clock is Since the pendulum rate will increase with an increase in gravity, and local gravity varies with latitude and elevation on Earth, precision pendulum clocks must be readjusted to keep time after a move. In the extreme case, one of the pallet pins may be driven with such force against escape wheel 10 that the pallet pin may be bent, broken or the escapement may be jammed.An anchor crutch or swing rod 22 is rigidly coupled to pallet arbor 14. This can run largest metal grandfather clock pendulum on the market along with added weight. Thus, post 24 supports the entire pendulum mechanism and removes this stress from the escapement. turned_in_out Chiming Pendulum Quartz Clock Movements. Thus, the error in time keeping which occurs during this period will be extremely small.Thus, in this invention, even when the clock is installed in an inclined angle, an automatic adjusting action will take place as soon as the clock mechanism is started into motion. The upper end of lever 32 extends into the central opening of ring portion 26a. The present invention includes a pendulum clock mechanism which includes an escape wheel with escape teeth disposed on a circumference, an anchor which pivots about a pallet arbor and which has at least two pallet pins which engage the escape wheel, a pendulum bob which acts as an oscillating time standard for the clock, and coupling parts, described below, which connect the pendulum with an anchor crutch fastened to the pallet arbor. This causes the position of anchor 16 to be corrected such that anchor 16 is in a proper designed position for escape action. The lever and pendulum arm are frictionally coupled such that when the equilibrium position of the pendulum arm is offset from the designed equilibrium position of the clock mechanism, the lever is automatically rotated such that the escapement is still driven about its designed equilibrium position.an escape wheel having plurality of escape teeth disposed on the periphery of said escape wheel;an anchor coupled to a rotatable pallet arbor and having two symmetrical pallet pins engageable with said escape wheel;a resilient swing member coupled to a pivot point at a first end and to said pendulum at a second end;a lever rotatably provided on said pivot pin at one end and coupled to said swing rod at the other end; anda slip spring provided on said pivot pin and applying a compressive force on said lever such that said lever is frictionally held at some first angle relative to said pendulum and such that whenever a torque greater than predetermined magnitude is exerted on said lever, said lever rotates to and maintains a second angle relative to said pendulum,whereby said escapement executes accurate time keeping motions without substantial dependence on alignment of said clock mechanism with the vertical as defined by gravity by automatically compensating for misalignments.an escapement for controlling speed and regularity of said pendulum; andmeans for coupling said escapement and said pendulum and for driving said escapement in a symmetric, periodic movement regardless of the disposition of said pendulum and an escapement with respect to the vertical, said means including;a swing member coupled to said pendulum and to support the weight of said pendulum about a pivot point, said swing member configured in the shape of a ring;a lever rotatably coupled to said escapement, said lever extending from said ring of said swing member towards the interior of said ring, said lever further being rotatably coupled to said pendulum at some first angle relative to said pendulum such that whenever a torque greater than a predetermined magnitude is exerted on said lever, said lever rotates to and maintains a second angle relative to said pendulum,whereby said escapement executes accurate time keeping motions without substantial dependence on alignment of said clock mechanism with the vertical as defined by gravity by automatically compensating for misalignments.MECHANICALLY-DRIVEN CLOCKS OR WATCHES; MECHANICAL PARTS OF CLOCKS OR WATCHES IN GENERAL; TIME PIECES USING THE POSITION OF THE SUN, MOON OR STARSOscillators acting by gravity, e.g.

It is to be understood that a conventional clock gear train may be driven by the regulated motion of escape wheel 10 and escape wheel arbor 12 according to principles well known to the art. Understandably, such an extreme case results in a complete and functional failure of the pendulum clock.Furthermore, another defect in conventional pendulum clocks is the vulnerability of the pallet pins to relatively mild shocks.

Accordingly, no improper torque is applied to the slip mechanism of the coupling parts and no slipping action occurs in the slip mechanism.FIG. However, this slip mechanism could also employ a coil spring or a frictional plate made of synthetic resin or any other well known or yet to be discovered equivalent in the art.
