  • Patent number: 8764280
    Abstract: An enhanced escapement mechanism provides improved isolation of energy and torque for an oscillation system, e.g. a pendulum. In an exemplary embodiment, during a first phase, a pendulum releases an impulse arm that is decoupled from a main wheel, which falls and impulses the pendulum, such as at or near the middle of the pendulum swing. In a second phase, the impulse arm continues to fall, becoming totally detached from the pendulum, wherein the falling impulse arm releases the main wheel, which restores the impulse arm to its initial position. The main wheel continues to rotate until it is no longer in contact with the impulse arm, and is captured, such that the process may be repeated. While the enhanced escapement mechanism typically provides an impulse to an oscillation system during each period, alternate embodiments provide an impulse for each of a plurality of periods, e.g. once every ten periods.

  • Patent number: 8475034
    Abstract: Enhanced compound pendulums provide thermal compensation and/or barometric compensation, such as for a mechanical clock system. The enhanced compound pendulums are simple to construct, and can be more easily compensated than conventional, single-bob pendulums. The enhanced compound pendulums typically comprise material that is added above the point of rotation. Thermal expansion factors for components of the enhanced compound pendulums may preferably be chosen to provide thermal compensation to the first order. In some embodiments of enhanced compound pendulums, volume is added above the pivot to provide barometric compensation, such as by equalizing the moments above and below the pivot, or by providing geometric symmetry above and below the pivot, with a lower density above the pivot.

  • Publication number: 20090073814
    Abstract: A gravity pendulum, referred to as a low-displacement pendulum because it does not displace air as it rotates, is disclosed. The low-displacement pendulum uses an unbalanced wheel instead of the more conventional suspended bob. Because the pendulum does not displace air as it rotates, it eliminates an important component of air drag that causes energy loss in a normal pendulum. The low-displacement pendulum also eliminates errors caused by variations in barometric pressure. In addition, it can be easily thermally compensated without the use of special materials, such as Invar.

  • Patent number: 6036358
    Abstract: A system and method are provided for calculating the period of a mechanical clock while minimizing the effects of extraneous noise. The method of the invention senses three sounds from the clock and calculates the period of the clock based on those three sounds. The method defines a blanking period between the first and the second sounds and the second and the third sounds. During this blanking period, the method ignores all sound to prevent such sound from being mistaken for sounds from the clock. The method also defines an expected time interval between sounds from the clock. The system senses the beats of a mechanical clock while minimizing noise. The system includes a pick-up device, an amplifier coupled to the pick-up device, and a microcontroller configured to control the gain of the amplifier so that the expected time delay interval becomes approximately equal to the actual time interval, thereby minimizing noise.

  • Patent number: 5886956
    Abstract: When front and rear pendulum arms are swung together under the action of a clock movement, the front pendulum arm can swing behind an article supported on a pin because a slit formed in the front pendulum arm allows the front pendulum arm to pass by the article supporting pin. The slit in the front pendulum arm is camouflaged not to exist by camouflaging patterns.Therefore, although the article is supported on the pin with a space from the back board, the front pendulum arm can swing behind the article. The slit is camouflaged not to exist, so that the article will seem as if it supported itself or were floating in the air.Since the front pendulum arm can swing behind the article, the illusion of the floating article in the air is further enhanced.

  • Patent number: 4395137
    Abstract: A method and apparatus for accurately controlling a timekeeping apparatus utilizing a relatively heavy free pendulum or other harmonic structure carrying a permanent magnet, and a powered harmonic structure carrying a ferromagnetic element. The magnet is positioned on its carrier in a manner to effect energy transfer between the pendulums or structures during intermittent periods of magnetic attraction as the two structures oscillate. The free structure governs the speed of oscillation of the powered structure to maintain accurate control over the latter and energy transferred from the powered structure to the free structure maintains continued oscillation of the governing, free structure.
