K'Nex Clock Escapement

A gravity powered pendulum escapement(clock mechanism), created with K'nex:

This mechanism used a chain with a weight at the end to drive a "ratchet" style clock escapement. The swinging element as connected to a pendulum controls the rate at which a toothed wheel is allowed to spin as the chain pulls across.

My apologies for the extremely poor images. These images where grabbed from a video tape (before I had access to a proper megapixel digital camera).
