  • Patent number: 7505372
    Abstract: An electronically controlled water clock designed to visually display the passage of hours, minutes and seconds by the gravitationally induced flowing away of liquid material inside transparent vessels, with each unit of time displayed in a separate vessel. Each vessel consists of an upper and lower chamber and an air tube connects the 2 chambers to equalize air pressure between them and to serve as an overflow drain for the upper chamber. The bottom end of the upper chamber has a small drain tube through which the liquid drains out. The front of the upper chamber is inscribed with a uniform scale and its interior shape is such that the upper surface of the liquid drops in equal vertical intervals over equal time spans throughout the entire time required to drain the upper chamber from the top to the bottom end of the scale.

  • Patent number: 5850373
    Abstract: A transmission mechanism for a magnet-bearing ornament, in which a clock main spring barrel serves to provide power required by the ornament to show a dynamic scene. The clock main spring barrel has a second wheel to replace a conventional second hand. The second wheel has a large number of teeth provided along its circumferential surface and meshes with a small driven gear to cause the latter to rotate at a high speed. The small driven gear may then cause a magnet-bearing member to coaxially rotate with it via a rotating shaft of the gear connected to the magnet-bearing member. Alternatively, the small driven gear is provided with a major rotational disc having magnets attached thereto. When the small driven gear rotates, the major rotational disc rotates synchronously to magnetically rotate the magnet-bearing member behind a background board of the ornament disposed between the clock main spring barrel and a front showing space.

  • Patent number: 4469447
    Abstract: An ornamental clock operates while submerged in a body of water, the clock having a clock face and relatively movable hands and a mechanism for moving the hands. Air bubble receivers are each mounted for movement between a first position to entrap air bubbles and a second position to release air bubbles into the water. Spaced ports deliver air into the water below each bubble receiver. Accumulation of bubbles alternately in each receiver produce buoyant forces which act through linkage to drive the clock mechanism. Apparatus is provided to deliver air alternately into the ports.

  • Patent number: 4455094
    Abstract: Apparatus is provided for moving an object in an oscillatory manner and in an arcuate path through the use of a fluid. The apparatus basically includes a hollow member or elongate tube having a curved portion and means for supplying fluid in pulses or at an increasing rate and then at a decreasing rate of flow to the tube on one side of the curved portion. The change in velocity of the fluid and the rate of change cause the movement of the tube due to inertia and, to a lesser extent, friction of the moving fluid within the tube. The density of the fluid also has a substantial effect on the movement of the tube, although gas alone will cause movement. The object to be moved is engagable by the tube and is usually supported by it. The object moved by the tube and fluid can take many forms, including signs, ornaments, figures, chimes, and clock dials.

  • Patent number: 4436434
    Abstract: A pneumatic timer has a bellows with a space inside it joined up with the outside atmosphere by way of an adjustable choke. For starting a timing operation, the bellows is compressed by a pneumatic actuator which is then automatically moved back so that the bellows' speed of motion back into its starting position is controlled by the choke adjustment. The end position of stretching of the bellows is sensed by a sensing unit. This sensing unit may furthermore be moved for adjustment in the axial direction of the bellows.

  • Patent number: 4372688
    Abstract: A liquid operated clock employs buckets pivoted to arms of a carrier rotating at constant speed. The buckets are sequentially moved below the surface of a liquid reservoir to fill the buckets, elevate them and cause them to discharge into a receiver. After a predetermined number of buckets of liquid have accumulated within the receiver, it is suddenly drained by a siphon tube back into the liquid reservoir. The change in weight of the receiver between full and empty conditions operates through a ratchet mechanism to drive the input shaft of a clock mechanism in an intermittent fashion. Cam and follower means control filling and dumping of the buckets.

  • Patent number: 4315327
    Abstract: An apparatus for connection to a periodic, pulsed air supply for providing an indication of time based on receipt of the air pulses comprises a rotor having an externally visible pointer. The rotor is mounted in a cylindrical housing and includes a first section which moves axially of the housing under the force of an air pulse. Teeth are formed on the rotor first section which coact with stationary teeth mounted on the housing interior to force the rotor first section to rotate a predetermined amount. This rotation is transmitted to a second axially stationary rotor section by a keyed connection between the rotor sections. The axially movable section is forced to its original position by a spring mounted in the housing.

  • Patent number: 4262348
    Abstract: This liquid clock has a lower liquid reservoir and an upper-liquid reservoir connected by an overflow to the lower reservoir. A plurality of timekeeping reservoirs are positioned to allow liquid in them to stand at the same level as in the upper reservoir. Each of the timekeeping reservoirs has a liquid exit orifice which connects to one of a plurality of timekeeping tubes, each having timekeeping related indicia on it. A means is provided for dropping a liquid displacement member in each of the timekeeping reservoirs at predetermined time intervals, thus displacing liquid into the timekeeping tubes. A means for withdrawing the liquid displacement members from the timekeeping reservoirs does so between the predetermined time intervals. A pump supplies liquid to the upper reservoir from the lower liquid reservoir to maintain the level of liquid in the upper reservoir at the level of the overflow. Means is further provided for periodically emptying the timekeeping tubes at time related intervals.
