<p>Technological utilisation of the force of gravity is proposed for driving a dynamo e.g. in apartments or private houses. A falling pendulum mechanism carries an end-weight(s) of calculated mass, e.g. centrifugal or flywheel mass working via a toothed-wheel ratchet, the pendulum receiving a small mechanical or electrical impulse at the correct turning moment. The ratchet has specially shaped teeth with lubrication facilities. The pendulum is fitted with an upper-mounted locking bolt which is pressed by a weak spring against the specially shaped teeth of the ratchet.</p> |
