Method of assembling and forming transformer cores with the use of an assembly box

Claim 1

THE METHOD OF FORMING A SUBSTANTIALLY RECTANGULAR TRANSFORMER CORE HAVING A SUBSTANTIALLY RECTANGULAR WINDOW FROM A PLURALITY OF INTERNESTABLE CIRCULAR WOUND TRANSFORMER CORE SECTIONS EACH HAVING A CIRCULAR CENTRAL WINDOW AND BEING BUILT UP OF LAYERS OF MAGNETIC CORE STRIP MATERIAL, COMPRISING THE STEPS OF, AT AN ASSEMBLY STATION LATERALLY COMPRESSING THE CORE SECTION OF LARGEST DIAMETER FROM DIAMETRICALLY OPPOSITE SIDES SO THAT IT BECOMES OVOID IN SHAPE AND THEN PLACING THE COMPRESSED CORE SECTION WITH ITS SHORTER LATERAL DIMENSION BETWEEN A PAIR OF RIGID FORMING PLATES WHICH ARE MAINTAINED BY SPACING MEANS IN PARALLEL SPACED RELATION TO ONE ANOTHER AT A SEPARATION EQUAL TO THE AFORESAID SHORTER LATERAL DIMENSION OF SAID CORE SECTION SAID FORMING PLATES HAVING FREE UPPER AND LOWER EDGES, INTERNESTING WITHIN THE LARGEST DIAMETER CORE SECTION THE CORE SECTIONS OF SUCCESSIVELY SMALLER DIAMETER BY ALSO LATERALLY COMPRESSING EACH SUCH SECTION IN TURN AND SLIPPING IT INTO THE SECTION OF NEXT LARGER SIZE UNTIL THE COMPLETE UNFORMED CORE IS BUILT UP BETWEEN THE SAID PAIR OF RIGID FORMING PLATES, TRANSFERRING THE UNFORMED CORE ASSEMBLY TO A FORMING STATION, SUBJECTING THE SAID FORMING PLATES TO A PAIR OF COLINEAR FORCES DIRECTED TOWARD ONE ANOTHER TO RENDER THE CORE MORE OVOID IN SHAPE AND RELEASING SAID PLATES FROM SAID SPACING MEANS; REMOVING SAID SPACING MEANS FROM THE VICINITY OF SAID CORE AND RELEASED PLATES AND PLACING A FORMING MANDREL HAVING AT LEAST ONE PAIR OF SPACED APART PARALLEL SIDES WITHIN THE WINDOW OF THE CORE SO THAT THE PARALLEL
