Abstract: A pendulum-regulated clock. The clock has a movement at the bottom of a multi-rod pendulum. In an embodiment, a first pendulum rod and a second pendulum rod are provided. The clock provides swinging motion by imparting an oscillating torque to one or more of the pendulum rods. In an embodiment, a dual escapement mechanism may be provided. A dual escapement mechanism may synchronize the dual escapements via differential adjustment, to uniformly power pendulum rods during both directions of swing.

Abstract: A pendulum box for a clock pendulum box includes a tumbler seat, a pendulum mover pivotally mounted on the tumbler seat, and a pendulum rod mounted on the pendulum mover and having a portion secured in the pendulum mover to move therewith. Thus, the pendulum rod is combined with the pendulum mover closely, so that the pendulum rod is moved with the pendulum mover synchronously. In addition, the pendulum rod is combined with the pendulum mover rigidly and stably, thereby preventing the pendulum rod from producing vibration or sway during movement.

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.

Abstract: A pendulum device comprises a pendulum rod, a support member for rockably supporting the pendulum rod to permit the pendulum rod to swing freely within a normal swinging angle, and a locking mechanism mounted on the support member for relative movement between first and second positions. The locking mechanism is operative in the first position to lock the pendulum rod from swinging freely and is operative in the second position to enable the pendulum rod to swing freely within the normal swinging angle.

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.

Abstract: A pendulum stem (16) not more than 4 inches in length has one end portion swingably connected to a pivot arrangement (18) and a concentrated mass (22) slidably located on the other end portion. Permanent magnets (56,58) secured to the mass (22) move past a pair of wire coils (60,62) during swinging movement of the stem and mass to induce a signal in the one coil (60). The signal actuates a circuit (66) to form a pulse that is applied to the other coil (62) at an appropriate later time to create a magnetic pulse driving the mass (22) and stem (16) along its swing path. The described pendulum drive applied to a miniature clock provides a slow-swinging pendulum having a period closely approximating that of a grandfather clock many feet in height.

Abstract: A structure of clock comprises a main body having a clock mechanism on upper portion, a battery and circuit chamber on medial portion, a pendulum chamber on lower portion and an oscilatory control device on the top thereof. The pendulum has a tubular member at the top having a pair of corresponding right triangular recesses formed at two ends respectively, which are made in registry with the right triangular support members on the oscilatory control device. Because the right triangular support members are sizely smaller than that of the right triangular recesses, it is characterized in that when the triangular recesses suspend from the triangular support members, the oscilatory span of the pendulum is restricted by the oscilatory device.

Abstract: A structure of an ultrathin clock comprises generally a roughly rectangular housing having partitioned into a first chamber on upper portion for disposing a clockwork mechanism and a dial, a second chamber on median portion for disposing a set of electric circuit and batteries, and a third chamber on the lower portion for pivoting a pendulum therein and a cover which is snap fitted to the third chamber for securing the pendulum. The pendulum has a magnet on the upper end directly under an electric coil inside the second chamber so as to actuate the pendulum to swing laterally upon the variations of the electromagnetic field between the coil and the magnet. This invention has been characterized in the thickness of the housing which is greatly thiner than that of the prior art.

A memory circuit stores a data table on the basis on which the operation timing of the stepping motor is determined. A control circuit controls the application of actuation pulses to the stepping motor on the basis of the data stored in the memory circuit. The data table is made up of numeric values representative of the inter-pulse spacing of the actuation pulses, the inter-pulse spacing being selected such that the rotational speed of the rotary decorative member varies in conformity with a sine curve or the rotation angle of the decorative rotary member varies in conformity with a secant function.

Abstract: In a clock provided with a mechanical drive for the going train and having one or more striking mechanisms controlled by the going train, the motion regulator of the going train comprises a quartz-controlled stepping mechanism whose arbor is in drive connection with the wheelwork of the going train via an escapement. The connection insures that each step of its arbor releases the going train subject to the torque of the mechanical drive for a defined angle. Thereby it becomes possible to use for the going train a commercial, i.e. low-torque, quartz controlled stepping mechanism and yet to have available the torques required for the control of one or more striking mechanisms. It is of advantage if, between the arbor of the stepping mechanism and the wheelwork of the going train gear, elements in the form of a pallet controlled by a cam plate or in the form of a worm wheel engagement are provided, which gear elements remain in self-lock but are releasable from the self-lock by the arbor.

Abstract: A rotary pendulum without time-keeping function, comprising an inertial body suspended from a clockwork housing of a preferably electronically driven timepiece through the intermediary of an elongate torsion spring, is periodically accelerated by the impact between a vane on the spring and radial camming teeth of an impeller wheel frictionally entrained on a horizontal seconds shaft of the timepiece via a spiral spring anchored to that shaft. The vane, near the upper end of the torsion spring, oscillates only through a half-cycle limited on the return swing by an abutment on the clockwork housing. The inertial body is secured to a latch member at the lower end of the torsion with the aid of a coupling ring on which a drag ring is rotatably mounted, the latter carrying a radial fin engageable with a fixed stop pin as well as with a peripheral lug on the coupling ring whereby the body can turn through almost two full revolutions before being positively arrested.

Abstract: A simulated pendulum clock has a pendulum which rocks to and fro for decorative purposes only thereby simulating a pendulum clock of the type having a rocking pendulum for timekeeping purposes. A transmission wheel is rotationally driven by the timepiece movement of the clock and a friction clutch mechanism transmits the rotational movement of the transmission wheel to a rotating member whenever the load on the rotating member is less than a predetermined value and otherwise enables slipping of the transmission wheel relative to the rotating member. A toothed escape wheel is coaxially mounted with the rotating member and is connected thereto through a coil spring which applies a rotating torque to the escape wheel. The teeth of the escape wheel coact with a pair of pallet pins of a pallet which is mounted to undergo rocking movement in response to alternative engagement and disengagement of the pallet pins with the escape wheel teeth.
