Electromagnetic pickup for electrical musical instruments

Claim 1

AN ELECTRICAL MUSICAL INSTRUMENT OF THE GUITAR TYPE, WHICH COMPRISES A BODY HAVING A FACE, A PLURALITY OF MAGNETIZABLE STRINGS MOUNTED IN TENSIONED RELATIONSHIP OVER SAID FACE AND DISPOSED GENERALLY PARALLEL TO EACH OTHER, SAID STRINGS LYING GENERALLY IN A COMMON PLANE WHICH IS GENERALLY PARALLEL TO SAID FACE AND SPACED THEREABOVE, AN ELECTROMAGNETIC PICKUP MOUNTED ON SAID BODY BENEATH SAID STRINGS, SAID PICKUP MOUNTED ON SAID BODY BENEATH GATED PERMANENT MAGNET ELEMENTS EACH OF WHICH IS DISPOSED GENERALLY PERPENDICULAR TO SAID PLANE OF SAID STRINGS AND IS BENEATH ONE OF SAID STRINGS, SAID PERMANENT MAGNET ELEMENTS BEING DISPOSED IN A ROW GENERALLY PARALLEL TO EACH OTHER AND IN SPACED RELATIONSHIP RELATIVE TO EACH OTHER, SAID PERMANENT MAGNET ELEMENTS ALL HAVING THEIR NORTH POLES ADJACENT SAID PLANE OF SAID STRINGS, A GENERALLY CHANNEL-SHAPED MAGNETIZABLE ELEMENT MOUNTED AROUND SAID PERMANENT MAGNET ELEMENTS, SAID CHANNEL ELEMENT HAVING A WEB DISPOSED ADJACENT THE SOUTH POLES OF SAID PARMANENT MAGNET ELEMENTS, SAID CHANNEL ELEMENT HAVING SIDE FLANGES DISPOSED ON OPPOSITE SIDES OF SAID PERMANENT MAGNET ELEMENTS IN SPACED RELATIONSHIP THEREFROM AND EXTENDING UPWARDLY TO EDGES WHICH ARE GENERALLY FLUSH WITH SAID NORTH POLES, SAID EDGES OF SAID SIDE FLANGES AND SAID NORTH POLES BEING SPACED DISTANCES FROM EACH OTHER AND FROM SAID PLANE OF SAID STRINGS WHICH ARE SUCH THAT LINES OF FORCE FROM SAID NORTH POLES WILL PASS LONGITUDINALLY THROUGH SUBSTANTIAL PORTIONS OF THE STRINGS ABOVE SAID NORTH POLES AND WILL THEN PASS DOWNWARDLY TO SAID EDGES AND THENCE TO SAID SOUTH POLES AND RESPECOF SAID FLANGES BEING SHAPED AS TEETH, THERE BEING ONLY TWO TEETH OPPOSITE EACH OF SAID NORTH POLES AND REPECTIVELY PROVIDED ON THE FLANGES ON OPPOSITE SIDES OF SAID MAGNET ELEMENTS, SAID TWO TEETH AND THE ASSOCIATED NORTH POLE THEREBETWEEN BEING DIRECTLY BENEATH ONE OF SAID STRINGS, AND COIL MEANS MOUNTED AROUND ALL OF SAID PERMANENT MAGNET ELEMENTS AND ADAPTED TO GENERATE ELECTRIC SIGNALS CORRESPONDING TO THE VARIATIONS IN THE MAGNETIC FIELD OF SAID PERMANENT MAGNET ELEMENTS CAUSED BY VIBRATIONS OF SAID STRINGS.
