A clock pendulum and movement have been designed which are never actually connected either mechanically, electrically, or magnetically, yet the movement drives the pendulum and the pendulum controls the movement. The usual “escapement” has been eliminated.

The clock has been made and tested; first in the form of a regulator, and then in the form of a heavy turret clock with triple worm gearing to the hands.

The power is derived from an electric motor in continuous motion; this raises a gravity arm which, in descending, drives the pendulum with a constant force. The motor also drives the clock hands, makes contacts to drive other dials, and may drive telescopes, chronograph drums, etc. After acting on the pendulum the gravity arm is arrested by a stop, and electric power passes to the motor while arm and stop are in contact. Current is interrupted when the motion of the motor raises the gravity arm. The speed of the motor is governed by the time of contact, but the motion of the motor is maintained between the periods of contact by a reduced current and by kinetic energy. Application has been made for a patent.
