Linear electric motor

9. A LINEAR ELECTRIC MOTOR FOR PROVIDING INCREMENTAL LINEAR MOVEMENT COMPRISING A FRAME, FIRST STATOR MEANS MOUNTED ON SAID FRAME AND INCLUDING AT LEAST TWO ADJACENT POLE PIECES, WINDING MEANS WHICH UPON ENERGIZATION MAGNETIZES SAID POLE PIECES, A FIRST PLUNGER MOUNTED ON SAID FRAME FOR LINEAR MOVEMENT RELATIVE TO SAID FIRST STATOR MEANS ALONG A LINEAR PATH, SECOND STATOR MEANS MOUNTED ON SAID FIRST PLUNGER FOR MOVEMENT THEREWITH AND INCLUDING AT LEAST TWO ADJACENT SECOND POLE PIECES, SECOND WINDING MEANS WHICH UPON ENERGIZATION MAGNETIZES SAID SECOND POLE PIECES, A SECOND PLUNGER MOUNTED ON SAID FRAME FOR LINEAR MOVEMENT RELATIVE TO SECOND STATOR MEANS ALONG A LINEAR PATH, SAID LINEAR PATHS BEING PARALLEL, EACH OF SAID PLUNGERS HAVING SURFACE FORMED WITH TEETH EXTENDING TRANSVERSELY TO ITS PATH OF MOVEMENT AND HAVING A CONSTANT TOOTH PITCH WITH THE TOOTH PITCH OF THE FIRST PLUNGER BEING DIFFERENT FROM THE SECOND PLUNGER, EACH OF SAID PLUNGERS BEING ELONGATE AND HAVING A PERMANENT MAGNET POLARIZED TRANSVERSELY WITH AN END MEMBER EXTENDING ALONG EACH SIDE OF THE MAGNET, SAID TEETH BEING FORMED IN SAID END MEMBERS WITH THE TEETH OF ONE END MEMBER BEING LONGITUDINALLY DISPLACED ONE HALF A PLUNGER TOOTH PITCH THE OTHER END MEMBER, SAID POLE PIECES OF EACH STATOR MEANS HAVING A SURFACE PARALLELING SAID PATH AND HAVING EQUALLY SPACED TEETH FORMED IN SAID SURFACE, SAID POLE PIECES OF EACH STATOR MEANS BEING DIFFERENTIALLY DISPOSED ALONG ITS PATH A FRACTION OF THE TOOTH PITCH OF ITS PLUNGER, AND CONTROL MEANS FOR CHANGING THE ENERGIZATION OF THE WINDING MEANS TO PRODUCE A LINEAR MOVEMENT OF THE SECOND PLUNGER WHICH IS A FRACTION OF ITS TOOTH PITCH AND A LINEAR MOVEMENT OF THE FIRST PLUNGER WHICH IS A FRACTION OF ITS TOOTH PITCH WHEREBY THE ALGEBRAIC SUM OF THE TWO MOVEMENTS OF THE FIRST AND SECOND PLUNGERS IS THE OUTPUT MOVEMENT OF THE MOTOR.
