Lockable adjustment means for self-converging adjustable yoke assembly

摘要

A self-converging adjustable yoke assembly comprises a lightweight plastic liner, sandwiched between saddle type horizontal coils and toroidal type vertical coils, with an attached rear for clamping the assembly on the neck of a picture tube. The periphery of the liner has three symmetrically mounted adjustment means each comprising a support base cemented to the yoke liner and to the horizontal windings, an adjustment screw having a hexagonal ball head and a locking cap. The adjustment screws engage the funnel of the picture tube for adjusting yoke tilt about the tube axis. The locking caps releasably secure the adjustment screws in position.
