Deflection yoke adjustment apparatus

A deflection yoke adjustment apparatus, for use with a television display system comprising a color television kinescope including a neck having a longitudinal axis and incorporating means disposed within said kinescope neck for producing three electron beams, and a deflection yoke comprising horizontal deflection coils for deflecting said electron beams in horizontal directions orthogonal to said longitudinal axis and vertical deflection coils for deflecting said electron beams in vertical directions orthogonal to said longitudinal axis;

• said deflection yoke adjustment apparatus comprising:
• a support structure receiving said kinescope and incorporating electrical means for energizing said kinescope;
• a horizontal deflection coil holder for supporting said horizontal deflection coils, said holder having a side surface, a trio of rear surfaces, and a pair of bottom surfaces;
• a plurality of moveable positioning rods coupled to respective ones of said surfaces of said holder for supporting said holder in such manner as to dispose said horizontal deflection coils in a location encircling said kinescope neck, with said side surface disposed at one side of said longitudinal axis, with two of said rear surfaces respectively disposed on opposite sides of said longitudinal axis, with the remaining one of said rear surfaces vertically displaced with respect to said longitudinal axis, and with said pair of bottom surfaces, respectively disposed on opposite sides of said longitudinal axis;
• said plurality of moveable positioning rods including:
• a first positioning rod extending substantially parallel to said directions of horizontal deflection and coupled at one end thereof to said side surface;
• second, third and fourth positioning rods, each extending substantially parallel to said longitudinal axis, with each of said second and third rods respectively coupled at one end thereof to a respective one of said two rear surfaces, and with said fourth rod coupled at one end thereof to said remaining rear surface;
• and
• fifth and sixth positioning rods, each extending substantially parallel to said directions of vertical deflection, with said fifth rod coupled at one end thereof to one of said pair of bottom surfaces, and with said sixth rod coupled at one end thereof to the other of said pair of bottom surfaces;
• and
• a plurality of selectively operable actuating means mounted on said support structure for adjusting the orientation of said horizontal deflection coils with respect to said kinescope neck, each of said actuating means being coupled to the remaining end of a respectively different one of said plurality of positioning rods, with the actuating means coupled to said first positioning rod causing movement of said first rod in a direction substantially parallel to said directions of horizontal deflection when selectively operated, with the respective actuating means coupled to said second, third and fourth positioning rods causing movement of the respectively associated rod in a direction substantially parallel to said longitudinal axis when selectively operated, and with the respective actuating means coupled to said fifth and sixth rods causing movement of the respectively associated rod in a direction substantially parallel to said directions of vertical deflection when selectively operated.
