Horloge à bille

Fan of VC but not only i am very proud to post some infos about a special clock (not VC unfortunately) but having some technical interests. Enjoy !!.


This clock has been invented by William Congreve in 1808 and after an article talking of that type of clock in the years 1970, some of them have been made at this time mostly by english watchmakers.


Description :

Metal (movement and structure) : Brass

High : 46 cm

Width : 33 cm

Depth : 32 cm

 Basis : mahogany


How it works :

It is easy to understand but not to translate in english. I try !!.

The fuse mecanical movement is setted horizontally at the top of the clock and allow the force to run it.

3 dials indicate the hours, minutes and seconds (this last one indicate only 15, 30, 45 and 60 seconds but 15 and 45 indication are unusefull).

A inclined plane under the movement is used to run a steel ball along the digged furrows.

The inclinated plane is linked to the mecanism by a stalk.

The ball is set on one side of the plane and runs as the plane is inclinated.

After 30 seconds of run it knock the end stalk that using the mecanism force lift up or down the plane and move the second hand from 0 to 30 (or 30 to 60).

The ball is so ready to start in the reverse way and strike again after 30 seconds the opposite stalk.
And so on ...


Follow the ball !!

Ball is reday to hurt the stalk that will change the inclination of the plane.

The inclination plane has changed the ball restart a travel.

Funny is not it ??

NB : the timing is not easy ar the only way is to increase or decrease the speed is to change the inclination of the plane.



its what they call a perpetual movement right? (nt)
