Definitions

  • ABSTRACT 22 i Oct 10 1973 A first tide wheel is fixed to the hour hand tube of a conventional clock movement, below the fit-up cover. [211 405,133 A first idler pinion fixed to a shaft journalled in the fitup cover engages the first tide wheel.
  • the pinion shaft 52 U.S. Cl. 58/3; 58/126 R has a Second idler Pinion above the P eever, which 51 Int.
  • the present invention utilizes a conventional clock movement. Such movements are widely available, and may be obtained in the form known as a fit-up, with a housing which provides dust protection.
  • a rigid front plate, through which the tubes and shaft for the hands extend, provides a surface for attachment to a dial plate, and thus for mounting the fit-up in a clock case.
  • the present invention can be implemented in conjunction with such a fit-up by very simple means, involving no rework of moving parts of the existing mechanism.
  • a first tide wheel is fixed to the hour tube, and through pinions on an idler shaft, drives a second tide wheel on a bushing which carries a tide hand.
  • This hand by its position with reference to an appropriate dial, indicates the stage of the tide cycle.
  • the dial may also carry the conventional clock figures, on which the time of day is shown by the ordinary hour and minute hands.
  • FIG. 3 shows the front view of dial suitable for a 24-hour movement, a tide hand to hour hand ratio is approximately 1.9326.
  • FIG. 1 illustrates a way in which the invention may be embodied in an otherwise conventional clock mechanism.
  • the fit-up only a portion of which is illustrated, has a dust housing enclosing a mechanism, not shown, which may be spring wound, synchronous motor driven, battery powered, or any other type which has an hour wheel 12 fixed to an hour tube 14 and rotating once in 12 hours or once in 24 hours.
  • a first tide wheel 16 is fixed to the hour tube 14,. preferably being mounted thereon by a bushing 18.
  • the wheel 16 is engaged by a pinion 20 on an idler shaft 22 journalled in the fit-up cover plate 24.
  • the shaft 22 On the opposite side of the plate, the shaft 22 carries a pinion 26, which engages a second tide wheel 28, the latter being fixed to a tide wheel bushing which is freely rotatable around the hour tube 14.
  • the clock may be provided with a conventional dial ring 32, mounted on the housing 10 and/or the fit-up cover plate 24, and carrying the dial 34.
  • the entire assembly is mounted in a clock case 11.
  • The'tide wheel bushing 30 extends through the dial, and carries the tide hand 36 on the face side of the dial.
  • the tide hand should be mounted in a way which permits it to be easily set, and there are various well known ways of doing this.
  • the drawing shows the hand mounted on a bushing 38 which is freely rotatable on the bushing 30, being held thereon by a retaining ring 40 press fitted on the end of bushing 30.
  • a helical spring 42 bears against a shoulder 45 on the bushing 30, and against a washer 44 freely movable on the bushing 30. This has the result of pressing the mounting bushing 38 against the retaining ring 40, so that the tide hand normally moves with the tide wheel bushing 30, but can be easily adjusted with reference thereto for setting purposes.
  • the gear ratios should be such as to provide the necessary relation in the rate of movement of the hands. If one tide cycle is shown on the dial, the tide hand should rotate in about 12 hours, 25% minutes. With a 12-hour movement a practical arrangement is obtained when the wheel 16 is provided with 86 teeth and the wheel 28 with 89 teeth. Where the idler pinions 20 and 26 have identical numbers of teeth, this gives a tide hand to hour hand ratio of 0.96629, and hence a rotation time for the tide hand of about 12 hours 25 minutes and 7 seconds.
  • the 86-tooth wheel 16 will have a pitch diameter of 1.3437 inches, the 89-tooth wheel 28 a pitch diameter of 1.3555 inches; the pinion 20 will have 30 teeth and a pitch diameter of 0.46875 inch, and the pinion 26, 30 teeth and a pitch diameter of 0.4569 inch. All of these can be made with 64 pitch tooling.
  • a tide hand to hour hand ratio of approximately 1.9326 is provided by appropriate gearing in a similar way.
  • FIG. 2 The face of a dial 34 for the clock with a l2-hour movement is illustrated in FIG. 2.
  • the conventional hour and minute hands, indicating a time of 10:05, are shown pointing to the usual indicia 46 on the outer periphery of the dial.
  • Markings 48 for the high tide, low tide and mid tide points are provided in the central area of the dial, and the shorter tide hand 36 shows the status of the tide cycle as about 3 /2 hours past high tide.
  • a dial 34A for a 24-hour movement is illustrated in FIG. 3.
  • mechanism for indicating the stage of tide cycles comprising a first gear wheel fixed on said hour tube beneath said cover plate, a second gear wheel rotatably carried .on said hour tube above said cover plate, a pinion shaft journaled in said cover plate, a first pinion on said shaft engaging said first wheel, a second pinion on said shaft engaging said second wheel, an indicating hand fixed with reference to and rotating with said second wheel, and a dial whereon said hand indicates stages of tide.
  • a timepiece utilizing a clockwork fit-up having a 24-hour tube, and including a first gear wheel fixed to said tube, a second gear wheel rotatably carried on said tube, a pair of pinions corotatably mounted and each respectively engaging one of said wheels, the rotation rate of said second wheel being substantially 1.9326 times that of said tube,'an indicator corotating with said second wheel, and a dial bearing indicia for two complete tide cycles, whereon said indicator denotes the tide'stage.
