Mechanical heterodyne oscillator

Claim 1

APPARATUS FOR ACTUATING PILES COMPRISING A HOUSING COUPLED TO THE END OF A PILE, A SOURCE OF ALTERNATING IMPULSES IN SAID HOUSING, SAID SOURCE BEING BALANCED WITH RESPECT TO THE AXIS OF THE PILE AND ADAPTED TO GENERATE ALTERNATING LINEAR IMPULSES DIRECTED AXIALLY OF THE PILE, A HEAVY METAL BLOCK IN SAID HOUSING EXTENDING FROM THE TOP TO THE BOTTOM THEREOF, SAID BLOCK HAVING PAIRS OF SPACED CIRCULAR RECESES IN OPPOSITE SIDES THEREOF, SAID RECESSED BEING VERTICALLY AND HORIZONTALLY ALIGNED, PLATELIKE MEMBERS ROTATABLY MOUNTED IN SAID RECESSES, SAID PLATE-LIKE MEMBERS CARRYING UNBALANCED BALL WEIGHTS CLOSURE PLATES SECURING SAID PLATE-LIKE MEMBERS IN SAID RECESSES, THE MOUNTIGN OF SAID PLATE-LIKE MEMBERS INCLUDING OPPOSED SHAFTS JOURNALLED IN THE BLOCK AND IN THE CLOSURE PLATES, AND ROTATABLE ABOUT AXES EXTENDING PERPEDICULAR TO THE AXIS OF HE PILE, WITH THE MEMBERS SPACED AT SUBSTANTIALLY THE SAME DISTANCE FROM THE AXIS OF THE PILE ON OPPOSITE SIDES THEREOF, THE CENTER OF GRAVITY OF EACH PLATE-LIKE MEMBER BEING ECCENTRIC TO THE AXIS OF ROTATION THEREOF, AND MEANS FOR ROTATING THE PLATE-LIKE MEMBERS ABOUT THEIR AXES IN UNISON IN OPPOSITE DIRECTIONS, WITH THE CENTER OF GRAVITY OF THE PAIR OF PLATE LIKE MEMBERS IN PHASE WITH EACH OTHER.
