"Moonlight" clock:

Movements of the Sun and the Moon over the horizon

Mechanical clock showing the apparent movements of the Sun and the Moon

Installation and use

Installation:

Install the shelf in the place you have chosen ( you must'n move it together with the clock ) but carry it gently.

Put the clock on the shelf ( with must be stable ). Hang the two weights to their own hooks. Hang the long pendulum and push it gently.

Check the horizontality of the clock in order two obtain a regular tic-tac.

Winding of the weights:

Once a weeck, you have to take up the chain above the weight and pull down the other end of the chain. Then it's going to work for about one week.

Too fast or to slow:

If it works too fast, lengthen the pendulum ( unscrew the nut under the weight of the pendulum ),

and if it works too slow, screw the nut.

Finalization of the time:

You have to turn the hands of the Sun and the Moon with the chain without end you must move gently on the left and down, and stop when the hour is right. When the Sun appears at East, on the horizon, the disc which seams the night-sky, turns and shows the blue-sky. When the Sun disappears at 6 PM, the same disc turns and shows the night-sky with stars.

Phases of the Moon:

Unlock the hand of the Moon by unscrewing carefully the central nut which prolongs the axel of the hands, and hold at its end, but not by the Moon itself. Bring the Moon ( black) in front of the Sun, on the ''New Moon'' day ( see the calendar ) . Then close the nut.

The little sphere, half black, half white, turns on itself automatically, and shows its phases ( quarters ) according to the position of its hand in relation with the hand of the Sun : black at the ''new-moon'' when it is in front of the Sun and white at the ''full-moon'' when the hand of the Moon is in the continuation of the hand of the Sun.

Maintenance:

Put once a year a drop of vaseline oil to each end of horizontal axels, on some teeth of the wheels and at every place where there is a friction between the metallic pieces.
