Abstract
This disclosure depicts getter support means for use in television cathode ray tubes. A getter support means is structured so as to be retained in the tube by the outward, self-retaining pressure of an expansible member on the inner surface of the neck adjacent to the junction of the neck and the funnel of the tube envelope. Support for the getter assembly is provided by attachment to the expansible member.
