  • Patent number: 4006301
    Abstract: This disclosure depicts a novel yoke adjusting apparatus for tilting a yoke relative to a central axis of a color television picture tube having a funnel with a flared portion and a neck containing an inline electron gun assembly. The yoke adjusting apparatus is illustrated as comprising; a circumferential support about the neck of the funnel and attached to the flared portion, a tilt adjusting means carried by the circumferential support for selectably positioning the yoke, a locking means for locking the tilt adjusting means in any selected position, and a manually operable means for releasing the locking means to free the tilt adjusting means and thereby enable it to be retracted and the yoke readjusted. The apparatus provides for simplicity and economy in readjusting the yoke at a later point in time after the initial adjustment.
