Abstract
Abstract The hour hand shaft of a clockwork has a first gear rotatably mounted thereon by a slip clutch. A second gear and a tide hand are secured on a bushing freely rotatable on the shaft. The second gear is connected to the first gear by a connecting gear. The second gear has a greater number of teeth than the first gear and the teeth are in selected number so that the tide hand will operate at a slower speed to proportion the rise and fall of the tides with the hours of the day. The connecting gear has a stem for rotatably adjusting the tide hand.

Claim 1
Independent Claim
181 words
A clockwork comprising a. a casing having a front face with time indications and tide indications, b. a driven hour hand shaft journaled in said casing and having an hour hand thereon movable around said face, c. a first gear rotatable on said shaft, d. a slip clutch connected between said first gear and said shaft arranged to normally drive said gear with said shaft but allowing adjustable rotation relative thereto, e. a second gear secured on said shaft for rotation therewith, f. a tide hand secured to said second gear and movable around said face, g. a connecting gear in common mesh with said first and second gears for connecting said gears in unitary rotation, h.
