Long period pendulum apparatus

A miniaturized operating grandfather style clock including an oscillating pendulum visible through a transparent front panel having an overall length from a pivot point to a lower and as short as 3 inches, comprising:

• a concentrated mass blob located spaced slightly from the lower end of the pendulum,
• permanent magnet means affixed to a rear surface of said blob;
• and
• magnetic field pulse generating means mounted adjacent the path of pendulum oscillation for providing periodic pulses of impetus to the magnet means and blob maintaining continuous pendulum oscillation of a period exceeding one (1) second including,
• first and second permanent magnets carried by the blob in spaced apart relation along the oscillation path with opposite polarity arrangement;
• first and second coil windings located adjacent the oscillation path such that the blob and permanent magnets move therepast at a relatively close spacing;
• an electric current pulse generating circuit having an input connected to the first coil winding, an RC time delay circuit, and an output connected to the second coil winding.

An authentic miniaturized clock, comprising:

• a housing for upright resting location on a ground plane having a generally transparent front panel;
• clockwork means in the upper part of the housing;
• a pendulum stem having one end portion pivotally mounted adjacent the clockwork means for hanging disposition and pivotal oscillation along a predetermined path;
• a centralized-mass blob secured to the stem adjacent the stem lower end;
• magnetically responsive means affixed to said blob including first and second permanent magnets secured to the blob in spaced apart relation so that as the blob moves along the predetermined path the permanent magnets move along said path one after the other;
• means located along the predetermined path of oscillation for generating magnetic pulses that cyclically drive the magnetically responsive means along said path at intervals exceeding about 1 second including first and second helically wound coils coaxially arranged such that as the first permanent magnet moves in a first direction past the first wound coil a signal is induced in said first coil which in turn produces a time delayed electric current pulse in the second wound coil driving the second magnet in the first direction, said time delay corresponding to an oscillating period exceeding about 1 second.
