  • Patent number: 8902717
    Abstract: A clock assembly containing a specialized clockwork. The clockwork contains a hub of three concentric posts upon which are mounted the second hand, minute hand, and hour hand of the clock. The post that connects to the second hand is the widest and shortest post on the hub. Consequently, when a second hand is connected to this outer-most post, the second hand can rotate under the minute hand and the hour hand closest to the clock face. By positioning the second hand post on the exterior of the hub, a 1:1 ratio can be maintained between the rotations of the clock motor and the rotations of the second hand post. This enables the full power of the motor to be transferred to the second hand post. Accordingly, the clockwork is capable of move, large, heavy, and unbalanced second hands.

    Abstract: An analog display includes a dial and a movable EL pointer positioned adjacent the dial for indicating a measured value. The pointer is an elongated EL lamp having a conductive pin extending through one end of the lamp and about which the lamp pivots. The pin is mechanically secured to the lamp and is electrically connected to the front electrode of the lamp. A hole larger than cross-sectional diameter of the pin is formed in the rear electrode and in the phosphor layer to prevent the pin from shorting the front electrode to the rear electrode. A conductive spring rests on the pin to provide electrical power to the front electrode. Power is supplied to the rear electrode either through a conductive ferrule attached to the rear electrode or through a resilient wiper. The wiper can be attached to the pointer or to the face of the dial. For plural pointers, concentric conductive pins are used with a sliding contact for the rear electrodes.

  • Patent number: 5280461
    Abstract: A timepiece is provided in the form of a body having a face which displays a sinusoidal path of multiples of twelve wavelengths within a circular periphery, and concentric rings on the face which intersect the path. An arm rotates about the center of the face a rate of one revolution per every twelve hours. A time-indicating pointer, mounted for guided longitudinal movement with respect to the arm, reciprocates with respect to the arm at one cycle per hour. The combined rotation of the arm and reciprocation of the pointer cause the pointer to follow the sinusoidal path, such that the pointer indicates hours by its circumferential position relative to the crests of the wavelengths and indicates minutes by its radial position relative to the concentric rings.

  • Patent number: 5105398
    Abstract: A three-handed clock has a single movement to rotationally drive the second, minute and hour hands. The rotary output of the movement is transmitted directly to the second hand and is transmitted through a transmission belt to the minute and hour hands. The use of the transmission belt eliminates the need for a gear train to drive the minute and hour hands thereby providing greater design flexibility and ease of assembly and maintenance.

  • Patent number: 5025429
    Abstract: A timepiece has rotatable hour, minute and second hands each carrying an energizeable element. Electric power is supplied to the elements carried by the hour and minute hands through sliding contacts and is supplied to the element carried by the second hand through electromagnetically coupled coils. The drive torque applied to the hour and minute hands is greater than that applied to the second hand and easily overcomes the frictional drag associated with the sliding contacts. The lower drive torque applied to the second hand may not be sufficient to overcome the frictional drag associated with sliding contacts and to avoid this problem, electromagnetically coupled coils instead of sliding contacts are used to supply electric power to the element carried by the second hand.
