Rocking mechanism

A rocking mechanism comprising:

• an unbalancing weight mounted on a driven wheel driven by a motor, a cam mounted on the wheel for controlling the action of a first switch connecting the motor to a battery, a second horizontal sensing switch connected in parallel with the first switch, all mounted in a frame which allows it to rock three-dimensionally, the relation of the cam to the weight being such that the whole system is in balance when the first switch is open thus bringing the horizontal sensing switch to a horizontal position at which time it will close to energize the motor which rotates the wheel together with its weight, which both unbalances the system causing it to rock from the horizontal to open the second horizontal sensing switch and also closes the first switch due to the action of the cam wherefore the motor will continue to drive until the weight has returned to its balanced position and the first switch is opened by the cam, at which time, due to the inertia of the total system, the rocking motion will continue for some time depending on friction, distribution of weight and restoring force.

A rocking mechanism comprising:

• an unbalancing weight mounted on a driven wheel driven by a spring motor, a linkage stop operatively connected to the wheel for controlling the action of an oscillating escapement operatively connected to the motor, and an actuating pin selectively engageable by the linkage stop, all mounted in a frame which allows it to rock three-dimensionally, whereby when the linkage stop is in a first position it interferes with the oscillating escapement and prevents the spring motor from unwinding, at which time the unbalancing weight is in a balanced position, with the distribution of weight within the frame being such that the pin actuation comes into contact with the linkage stop, forcing the linkage stop to move out of interference with the oscillating escapement and allowing the spring motor to unwind, whereupon the unbalancing weight and the linkage stop will make one revolution and come to rest as before wherein the linkage stop interferes with the oscillating escapement, with the revolution of the unbalancing weight setting the arrangement rocking, with rocking continuing until the motion subsides enough for the actuating pin to be again moved.
