Abstract
Abstract A first tide wheel is fixed to the hour hand tube of a conventional clock movement, below the fit-up cover. A first idler pinion fixed to a shaft journalled in the fit-up cover engages the first tide wheel. The pinion shaft has a second idler pinion above the fit-up cover, which engages a second tide wheel on a tide wheel bushing rotatably carried on the hour hand tube. The tide hand is frictionally carried on the tide wheel bushing so that it can be slipped for setting to correct indication. A dial is provided, on which the tide hand indicates the hours to or from high tide, low tide and mid tide.

Claim 5
Dependent Claim
117 words
In conjunction with a 12-hour clock movement fit-up having a fit-up cover plate, and wherein the hour hand is mounted on an hour tube extending through the fit-up cover plate, the improvement consisting of an 86 tooth wheel fixed to the hour tube, an 89 tooth wheel on a bushing rotatably carried on said hour tube, a pinion shaft carried by said fit-up cover plate, a pair of pinions of like numbers of teeth, corotating on said pinion shaft and each respectively engaging one of said wheels, an indicating hand on said bushing, rotating with said 89 tooth wheel, and a dial whereon said hand indicates stages of tide, said dial bearing indicia for one tide cycle.
Claim 6
Dependent Claim
117 words
In conjunction with a 12-hour clock movement fit-up having a fit-up cover plate, and wherein the hour hand is mounted on an hour tube extending through the fit-up cover plate, the improvement consisting of an 86 tooth wheel fixed to the hour tube, an 89 tooth wheel on a bushing rotatably carried on said hour tube, a pinion shaft carried by said fit-up cover plate, a pair of pinions of like numbers of teeth, corotating on said pinion shaft and each respectively engaging one of said wheels, an indicating hand on said bushing, rotating with said 89 tooth wheel, and a dial whereon said hand indicates stages of tide, said dial bearing indicia for one tide cycle.
Claim 7
Dependent Claim
54 words
The invention as defined in claim 4, wherein said 86 tooth wheel is mounted on said hour tube beneath said fit-up cover plate and engages a first pinion on a shaft extending through said fit-up cover plate, said shaft carrying a second pinion above said fit-up cover plate which engages said 89 tooth wheel.
Claim 8
Dependent Claim
48 words
The invention as defined in claim 4, wherein said dial carries conventional 12 hour clock markings, a minute tube extends through said hour tube and carries a minute hand, and said hour tube carries an hour hand, said hour and minute hands indicating solar time on said dial.
Claim 9
Dependent Claim
25 words
