ABSTRACT OF THE DISCLOSURE This disclosure depicts and describes a unitized, in-line electron gun for television cathode ray tubes having a bead-type structure for mechanically supporting, spacing, and aligning gun components. This disclosure is particularly directed to an improved structure which promotes a greater stability of electrode support with a reduced tendency toward bead fracture. The electrodes being supported as a coherent unit in spaced tandem succession along the gun's central axis by claws on the electrodes embedded in two elongated axially oriented structural beads positioned on opposite sides of the electrodes. One of the electrodes has on each side thereof a pair of widely spaced, relatively narrow claws integrally formed with the electrode, and lying respectively in planes transverse to the gun axis, with the claws embedded at widely spaced points on the glass bead to enhance the lateral stability of the electrodes.
