Abstract
A device for thumping and flushing a kinescope funnel includes a lift member which moves horizontally to engage the funnel and then vertically to raise the funnel to a thump position. A means for centering and orienting the neck moves in unison with the lift member. A thumper is arranged to thump the funnel in the thump position. A probe vertically moves to enter the funnel through the neck and inject a flushing fluid into the funnel while thumping occurs.
